Description

Spraying device, method and adapter

The present invention relates to spraying devices, particularly refillable bottle spraying devices, which are refillable or refillable. In particular, the present invention relates to a spray bottle having a chemical container and a refillable container for water or solvent associated with the bottle spray so that it can be The spray bottle can be refilled by adding water or solvent to the refillable container.

Additionally, the present invention relates to bottles and spray devices for use with the refillable spray devices of the present invention.

Spray bottles are known for spraying chemicals (eg, water, detergents, soaps, insecticides, hairspray, etc.). Products that were previously contained and sprayed in aerosols are now being converted to spray bottles due to regulations to limit the amount of volatile organic carbons (VOCs) released into the atmosphere.

Bottlers typically buy empty plastic bottles and spray heads separately to package their products. Bottlers then refill, install, seal and label the finished spray bottles for distribution to retailers. The consumer buys a filled spray bottle at a point of sale and then uses the chemical contents of the spray bottle. Most consumers throw away the spray bottle once the contents of the spray bottle are used up once. However, spray bottles are still perfectly usable for filling and spraying chemicals, since plastic bottles are inherently chemically resistant and the spray tip remains fully functional after the contents of the bottle have been used. Conventional point-of-sale squirt bottles can be refilled several times with chemical concentrate and water (ie, at least 10, possibly 100 times and still be fully functional). As a result, consumers discard large quantities of reusable products (ie, empty spray bottles) that have a high use value.

In an era where there are many regulations to control pollution, and consumers and industry are aware of the need to conserve resources and reduce pitfill waste, it is desirable to promote the reuse of products that still have value in use, rather than simply discarding them that are no longer useful. value product. Many bottlers now sell concentrates in containers of various sizes to allow consumers to fill point-of-sale squirt bottles with the specific concentrate. However, it is clear that many consumers are reluctant to use this method due to the somewhat inconvenient process step of refilling the spray bottle. Specifically, there is some inconvenience in removing the spray head, opening the chemical concentrate container, pouring the chemical concentrate into an empty spray bottle, adding water, and reinstalling the spray head on the bottle. And, since consumers lack the experience and knowledge of the chemists working for bottlers to mix and dilute liquids, they are obviously reluctant to fill spray bottles. In addition, due to splashing of chemical concentrate when pouring it from one container into another, spillage, occasional tipping of a bottle being filled due to instability of an unfilled bottle, and other possible Unforeseen accidents make refilling often a messy job, causing great inconvenience to consumers.

What's more, it is quite dangerous for consumers who are not aware of the strong chemical nature of chemical concentrates to transport and handle containers of comparable size (eg: pints, quarts, gallons, liters) containing chemical concentrates . Specifically, spilled chemical concentrates can damage household items such as floors, carpets, kitchen and bathroom coverings, shelving, and other items that may come into contact with the chemical concentrates. Not only that, occasional contact with chemical concentrates may cause tissue burns and other injuries, thereby posing a great threat to human health.

Not least, chemical concentrates also pose a danger to children who may accidentally swallow them and become poisoned.

The main idea of the present invention is to provide a refillable spraying device, in particular a spraying bottle having at least one chemical supply to allow the spraying bottle to be refilled at least once. Chemicals can be gaseous, liquid, semi-solid or solid. Specifically, the liquid chemical formulation may be a single-phase mixture, a two-phase mixture, a suspension, or any other chemical agent that is characterized as a liquid. Semi-solid chemical preparations may be in the form of suspensions, pastes, solid particles suspended in liquids but still exhibit some liquid characteristics, and solid ones may be in the form of powders, granules, flakes or other solid matter forms.

The chemical formulation is preferably a chemical concentrate so as to be easily diluted with a solvent, in particular ordinary water. Preferably, the chemicals are diluted immediately, however, chemicals that take 24 hours or more to dissolve may be suitable for some applications.

The preferred embodiment of the present invention involves the spray bottle itself connected to a portion of chemical formulation. Rather, the chemical is stored in a manner that is directly connected to the inside or outside of the spray bottle. However, the scope of the present invention is broad enough to include a chemical formulation and bottle spray device assembled together (ie, directly connected) for sale at a point of sale. In one embodiment of the present invention, the consumer will buy a package that includes a supply of chemicals and a spray bottle, and after returning home, the consumer can take the spray bottle that has been filled by the bottler from the bottle. Remove from the packaging and store the chemical portion of the packaging separate from the spray bottle at home. The stored chemical formulation can be used to refill the spray bottle once the user has used up the original contents of the spray bottle.

A preferred embodiment of the present invention stores at least one dose of chemical formulation directly or indirectly inside or outside the spray bottle. In the case of an indirect connection to the spray bottle, mechanical fasteners such as plastic straps are used to attach the external chemical container to the spray bottle. In the case of a direct connection, the chemical container is directly internally or externally connected to the spray bottle. The preferred embodiment of the present invention stores at least one portion of the chemical formulation within the spray bottle, particularly within the bottle portion, so that any inadvertent splashes or spills can be accommodated during the life of the spray bottle. leakage. The advantages of these preferred embodiments are ease of handling, refilling, protection of household items from chemical agents and, most importantly, protection of children from inadvertent ingestion. This is especially important since the chemical concentrates sold by bottlers at the point of sale are much more potent than the diluted chemical formulations.

The preferred embodiment of the present invention also utilizes an existing bottle spray assembly comprising a plastic bottle, plastic spray tip and plastic conduit. In order to facilitate the application of the products of the present invention, and due to the large volume of sales and consumption, it is quite important to utilize readily available and relatively low cost standard components. Therefore, there is a great need for a chemical container for adding chemical agents.

The preferred refill chemical container is an insert that fits into the bottle portion of the bottle spray device. Such inserts can be manufactured in high volumes at very low cost, yet provide all the good features necessary for a safe and reliable product. In particular, such inserts can be made with one or more chambers or cells that contain the chemical and can be accessed in a number of ways. For example, the container is sealed with a membrane which can be pierced with a tool, in particular the tip of a catheter. Alternatively, the wall of the chemical container is designed or made into such a shape that once an external force acts on the chemical container, the container is easy to break. Adding lines of weakness, thinning the sidewalls, and other methods of locally reducing the strength of chemical container sections can all be used in the present invention.

In addition, one or more components (eg, bottle body, spray head, conduit) of an existing spray bottle can also be modified to become a chemical container. For example, modify the bottom or side wall of the bottle, mold the chemical container on the bottom, one side wall or multiple side walls of the bottle body, the spray head part can also be provided with the chemical container, and/or the conduit can be provided with the refill type chemical container, or mold the sidewall of the conduit with the chemical container.

However, these means are significantly more expensive due to the modification of existing components, whereas the insert according to the invention does not require modification of existing components.

The inserts of the present invention can take different forms and configurations. A first preferred embodiment of the insert consists of a cylinder within which one or more chambers or cells are located. The interior of the cylinder may be provided with one or more dividing walls, thereby forming a number of chambers along the length of the cylinder. Plastic cartridges with one or more dividing walls are easily extruded from plastic. The top and bottom of one or more chambers of the insert are sealed with upper and lower sealing films, respectively. The film may be plastic foil, metal foil, a composite of plastic foil and metal foil, or other suitable material that is both chemically resistant and easily punctured by a tool, particularly the end of a catheter, or burstable. compound.

The upper and lower sealing films are attached to the insert by bonding, gluing, thermal bonding, ultrasonic welding, or other suitable means capable of forming a fluid-tight seal.

The insert in this embodiment can be sold in a filled spray bottle at the point of sale. A conduit passes through an open chamber of the insert into the lower portion of the bottle to reach the pre-mixed chemicals added by the bottler at the time of manufacture. After the user has consumed the chemical, the spray head is unscrewed and the catheter is lifted from the bottle. The inserter is rotated so that a chemical container is now located where the previously opened chamber was located (ie, aligned to be pierced by the catheter). The user then forces the catheter through the upper sealing membrane, sequentially through the chamber, and punctures the lower sealing membrane. Water is added to the open chamber of the insert either before or after the step of piercing with the catheter to the chemical container. This configuration allows the chemical to remain stored within the spray bottle, simplifying the steps required to refill the spray bottle.

The consumer has no trouble removing the spray head and tube from the bottle, turning the insert, puncturing the chemical container, adding water through the open chamber of the insert, and reinstalling the spray head portion on the bottle. In addition, the chemical concentrate stored in the insert is relatively safe to handle and prevents accidental misuse by children (i.e., children must be able to unscrew the spray tip portion from the bottle, remove the catheter from the bottle, and successfully puncture the spray head). broken insert) and, in the event of a child piercing the insert, the opening through the upper sealing film is small enough that substantially most of the chemical does not splash out, thereby preventing the child from easily ingesting the chemical . Thus, the present invention provides a measure of substantial safety to the current manner in which point-of-sale outlets sell large quantities of chemical concentrates, thus allowing consumers to handle and mix chemical concentrates at home.

A particular insert may have one, two, three, four or more mutually independent chambers or units. For example, if there are four units, one of which is the open unit, and when initially filling the injection device with diluted chemical, the bottler will first pass the conduit through the open unit during installation. Thus, in this embodiment, the remaining three units serve as three separate chemical containers. This four-unit configuration allows the user to first consume the pre-mixed chemical in the spray bottle and then refill the spray bottle at least three times to consume all of the chemical in the spray bottle. If the consumer disposes of the spray bottle at this time, the utilization rate of the spray bottle is at least three times higher than that of the current spray bottle which is only used once before being discarded. Thus, if fully utilized, the consumption of the spray bottle is reduced by a factor of 3 (ie 1/4 waste).

Not only that, the present invention can even bring more convenience to consumers. Specifically, the insert is also available as a single piece at the point of sale, and it can be added to the spray bottle without the insert after consuming the contents of an existing point-of-sale bottle spray device. It can also be used with the bottle spray device of the present invention having an insert on the device, or after the insert sold with the bottle spray device has been exhausted.

This new device will significantly reduce the shipping weight and costs associated with it, reduce the retail shelf footprint where the product is sold, and especially reduce the consumption and waste of plastic. Specifically, the amount of plastic required to manufacture the four-chamber insert described above is comparable to the amount of plastic required to manufacture four existing bottle spray devices, given the same amount of dilute chemicals available. Than is very little. Furthermore, when the chemical agent is completely consumed, the insert is of little use compared to an empty existing spray bottle, which can be reused several times. Moreover, the production costs of existing bottle spray devices are significantly higher relative to the production costs of the inserts of the present invention, and the inserts of the present invention are compared with existing bottle spray devices to significantly save labor and others. Associated direct and indirect costs. Furthermore, if an entire system were established to reprocess the inserts of the present invention, such inserts could be easily recycled and possibly refilled, but, for reasons of convenience, there is a high probability that such inserts would be discarded by consumers .

The insert of the second embodiment of the present invention involves forming a strip of chemical containers that can be located within the body of a bottle spray device. The strip of chemical containers can be produced at high speed, most likely as a continuous strip, which can then be cut to length and distributed in isolation from each other in each injection unit. The strip-like insert can be manufactured using high speed molding techniques such as vacuum forming plastic strips into chemical containers, filling the chemical containers with chemicals, and sealing the chemical containers. The prepared strips are cut to length according to the number of containers to be attached to the bottle spraying device, and then attached to the inner surface of the bottle by bonding or other techniques. Chemical containers made of plastic strips are made to be punctured by a tool, in particular the end of a catheter, or ruptured by means of an external force applied to the chemical container. A user may burst one or more (ie, one, two, three, etc.) chemical containers to prepare a diluted chemical formulation having a specific concentration. Therefore, the idea of the present invention can allow the consumer to freely choose the concentration, which is not available in the current bottle spray devices.

In a third embodiment of the present invention, a plurality of cylindrical chemical containers spaced apart from each other are attached inside the bottom. A cylindrical chemical container is provided with an upper sealing membrane which can be pierced by a tool, in particular by the end of a conduit. The cylindrical container is divided into a number of individual units, or connected together by straps, or connected together by other means. The cylindrical chemical container is preferably positioned on the bottom wall of the base so that the end of the conduit is easily accessible when piercing the container.

In a fourth embodiment of the invention, the cylindrical chemical container is bridged to the side wall of the bottle. Cylindrical containers are made to rupture by simply squeezing against the side walls at specific points of the container.

In a fifth embodiment of the present invention, separate annular chemical containers are added to the existing conduit. The circular chemical container is made to be punctured or broken to obtain the chemical formulation. Alternatively, one or more apertures may be provided in the inner surface of the annular container and the conduits themselves may be used to seal these apertures (gluing may also be used to ensure a complete seal). In this structure, the annular container can be simply pulled away from the conduit, thereby exposing the opening on the inner wall of the annular container, and the chemical agent in the annular container can be obtained. It is also possible to unscrew the nozzle part from the bottle and lift the catheter until the bottom ring container is at or close to the mouth of the bottle. At this time, pinch the ring container at the mouth of the bottle with the fingers of one hand and lift the catheter with the other hand. To disengage the ring-shaped container from the conduit, and then let go so that the ring-shaped container falls into the bottle, so that the ring-shaped container can be removed. Before or after this, water is added to dilute the concentrate to form a diluted chemical formulation.

In a sixth embodiment of the invention, the insert is provided with a set of containers arranged in a ladder. Vessels at the top are narrower and deeper than those at the bottom that are wider and shallower. The size of one or more containers located between the top and bottom containers is between the dimensions of the top and bottom containers. This ladder-like structure makes it easy for tools, particularly the ends of the conduits, to approach any one of the chemical containers so as to pierce the sealing film on each container.

In a seventh embodiment of the present invention, a plurality of containers are arranged in the insert and distributed in layers. The top and bottom of each container are sealed with an airtight film. A person using a bottle-shaped spray device comprising such an insert first punctures the upper and lower sealing membranes of the upper container during the first refilling process, and during the second refilling process, in order to obtain The chemical agent pierces the upper and lower sealing films of the intermediate container, and similarly, in the third filling process, pierces the third chemical container.

Another mode of the invention focuses on utilizing a liquid chemical concentrate as the preferred source of chemical concentrate. The preferred embodiment of this mode involves a refillable bottle spray device having a liquid chemical concentrate container for holding a liquid chemical concentrate that can be filled or refilled one or more times irrigation. In a preferred embodiment of the present invention, the liquid chemical concentrate container is located within the spray bottle, wherein the liquid chemical concentrate is safely and securely stored. Furthermore, in a preferred embodiment of the present invention, the size and configuration of the liquid chemical container are selected so as to obtain a predetermined concentration of the liquid chemical concentrate so that the spray bottle can be refilled at least once, preferably one to ten times, It may also be up to 100 times. Additionally, in embodiments of the present invention, the spray bottle is provided with another opening (e.g., a second neck with a sealing cap) so that diluents such as water can be added to the spray bottle instead of from the spray bottle. The bottle spray device can be refilled by removing the spray head from the bottle. This structure allows the user to simply add water to the spray bottle to refill it without adding liquid chemical concentrate after the user has consumed the water in the spray bottle (i.e., a full charge), because The concentration of chemical concentrate in the liquid chemical concentrate container is high enough that the spray bottle can be replenished with water one or more times.

The preferred embodiment of this mode of spray bottle is also designed so that the liquid chemical concentrate container contains only enough chemical concentrate to fill the spray bottle once. In the embodiment of this chemical product, no water is added in the spray bottle when it is shipped and sold at the point of sale, thereby greatly reducing the shipping weight of the chemical product of the spray device with a spray head. Consumers add water to the spray bottle after purchasing it, but also consume the liquid chemical concentrate after using up the added water. Additionally, the liquid chemical concentrate container may also contain additional liquid chemical concentrate to allow more than one addition of water to the spray bottle. However, such one or more fillings are permitted since the spray bottle is initially shipped without water in it.

The liquid chemical and solvent containers can be arranged in many different ways. These containers may be separate, attached to each other or not, may also be interconnected containers, may also be one container inside another container, or may be other types of structures. Having a self-contained liquid chemical container within an existing container, such as an existing spray bottle, is highly desirable because there is no need to modify or modify the molds of existing liquid containers and they can be used directly in the present invention . Instead, a key aspect of the present invention is the development of a drop-in liquid chemical concentrate container that fits into existing containers such as spray bottles. Furthermore, it is also highly desirable to be able to still use existing spray heads in spraying devices, thus avoiding the development and manufacture of new and modified spray heads. The adapter of the present invention allows the self-contained liquid chemical container to be fitted to an existing spray head and allows the self-contained liquid chemical container to be placed in an existing spray bottle.

The adapter structure of the present invention utilizes a conduit inserted into a spray bottle and a conduit inserted into a liquid chemical container. The adapter includes a mixing chamber where the liquid chemical concentrate and water are mixed before reaching the active spray head. In addition, the adapter of the present invention is uniquely shaped to minimize the space required to store liquid within the spray bottle. The adapter is located in the normally air-occupied space of the spray bottle (ie, the neck or upper portion of the bottle), and its structure is easily moldable, low cost in mass production, and requires little assembly. This unique structure should minimize the difficulty of retrofitting existing production lines or bottlers.

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

The bottle spray device of the present invention includes one or more containers for holding chemicals or reagents (ie, chemical containers).

The chemical container may be a self-contained unit in indirect communication with the bottle spraying unit through encapsulation, or directly in communication with the bottle spraying unit through an external or internal connection to the bottle spraying unit. A preferred embodiment includes one or more internal chemical containers, preferably located within the bottle, so that accidental splashing or leakage of chemical agents from the one or more chemical containers is completely prevented.

In the case of an external connection to the bottle spray unit, mechanical fasteners such as plastic joints or plastic strip connectors can be used to attach the chemical container to the bottle or spray head portion, or Connect, and connect with its nozzle part.

Alternatively, the chemical container may also be formed as an integral part of the bottle, spray head section and/or conduit. In an integral embodiment, the chemical container may be incorporated directly into the assembly of the bottle spray device using adhesives, plastic welding, plastic forming processes (eg, molding), or by other means.

In a preferred embodiment, the spray bottle is provided with one or more separate chemical containers so that the spray bottle can be refilled one or more times. In a most preferred embodiment of the present invention, the bottle spray device is equipped with one or more chemical containers so that the user can use more than one chemical container in one refill operation, thus by specific refilling, i.e. The concentration of the chemical agent in the mixture can be increased (eg, 2-fold, 3-fold, 4-fold, etc.).

These chemical containers can be the same device to simplify the manufacturing process and reduce manufacturing costs, or conversely they can be chemical containers of different sizes, shapes and/or configurations. For example, both internally connected chemical containers and externally connected chemical containers can be used, and/or these chemical containers can be integrated or independent of each other.

The one or more chemical containers of the spray bottle can hold a chemical or multiple chemicals. In particular, the container may be filled or partially filled with a single compound, or a single-phase or two-phase chemical mixture, suspension, or other type of liquid chemical formulation. In addition, the chemical formulation may be a solid substance in the form of flakes, powders, granules, or a semi-solid form such as a suspension. In general, the container should contain a chemical that is easily diluted or dissolved with a solvent, specifically plain water.

A preferred embodiment of the bottle spray device 10 of the present invention is shown in Figures 1-5. The spray bottle comprises a spray head portion 12 which includes an internally threaded connector 16 which is threaded onto an externally threaded neck of the bottle body 14 . A conduit 18 is connected to the spray head portion 12 and inserted into the bottom of the bottle 14 .

Arranged on the spray bottle 10 is an insert 20 with three chambers 22 , 24 , 26 spaced apart from one another. In the embodiment of the insert 20 shown in FIG. 2 , the insert has a flange 28 on the upper portion of the insert 20 . The diameter of the flange 28 is larger than the inner diameter of the threaded neck 30 of the bottle 14, as shown in FIG. As such, the flange 28 functions to suspend the insert 20 within the bottle 14 .

Chambers 22, 24, 26 are respectively used to store predetermined quantities of liquid chemical concentrates. The tops of the chambers 24, 26 are sealed with an upper sealing membrane 32 and the bottoms of the chambers 24, 26 are sealed with a lower sealing membrane 34, as shown in FIG. Chamber 22 is open (ie, not covered by sealing membranes 32, 34) to accommodate conduit 18 and also to facilitate the addition of a solvent, such as water, into bottle 14 through the insert.

Insert 20 is preferably made of a suitable plastic material, and upper sealing film 32 and lower sealing film 34 are preferably made of suitable plastic film, foil, or other suitable single or composite layers. The membrane should be chemically resistant to the contents and be able to form a fluid-tight seal with the insert. Upper sealing film 32 and lower sealing film 34 can be attached to insert 20 in a variety of ways. For example, membranes 32, 34 may be attached to the insert by bonding, gluing, heat welding, ultrasonic welding, or other suitable methods known in the art to liquid-tight (ie, seal) chambers 22, 24, and 26.

The insert 20 shown in Figure 1 may be replaced by a variety of other inserts of suitable construction. For example, Figure 6A shows an insert 20' with 5 chambers, which has an open central chamber 36 and four chemical chambers 37, 38, 39 and 40; 41, 42, 43, 44 inserts 20″. In addition, the length of the insert relative to the length of the bottle 14 may vary according to the concentration of the concentrate used in the insert. Specifically, the higher the concentration of the concentrate, the The smaller the volume of the chamber requiring the insert, the correspondingly less length of the insert is required.

The insert 20 can be manufactured by various processes, however, injection molding or extrusion molding processes are the most suitable manufacturing methods.

The insert 20 can be sold in a bottle at the point of sale, or it can be sold separately to be inserted into an existing spray bottle.

When the insert is sold resting in a bottle, its three chambers 22, 24, 26 are initially chemical containers. Water or other suitable liquid diluents are filled in the bottle, and the upper sealing film 32 and the lower sealing film 34 of the sealing chamber 22 are punctured with the end of the conduit 18, and the conduit is inserted in the bottle, then, the shower head is tightly Install it on the bottle body to complete the packaging process. Alternatively, the chamber 22 may be open (that is, there is no liquid concentrate mentioned above in the chamber 22), and the diluted chemical preparation of the appropriate concentration is pre-filled in the bottle. When assembling, the conduit 18 is passed into the open chamber. Room 22, sold with bottle. In the three-chambered embodiment shown in FIG. 3, chambers 24 and 26 are sequentially pierced by the consumer and the two additional concentrates contained in chambers 24, 26 are dispensed into the bottle. Water can be added to the bottle 14 through the empty chamber 22 before or after the step of administering the medicament by the consumer.

The strip 110 is attached to the inner surface of a wall of the bottle body 104 . The specific location of the strip 110 can be changed from that shown in FIG. 7 to other locations on the sidewall and/or bottom of the bottle body 104 . Each chemical container 112 is configured so that when the surface of the container 112 is poked with the end of the conduit 108, the container 112 can rupture, or when the outer wall of the bottle 104 is pinched, one or more chemical containers 112 can be crushed. For example, the chemical container 112 can also be made with one or more weakening lines on its wall, as shown in FIGS. 8 and 9 .

The strip 110 is preferably made very long, and then cut to the required length during specific use. Thus, different sized bottles may have correspondingly more or fewer individual chemical containers 112 . In addition, making the strip 110 very long can also increase the productivity of the strip 110, thereby increasing the productivity of bottling. In the embodiment shown in FIG. 8 , the strip 110 is provided with an adhesive layer 116 for adhering a sealing layer 118 to the back of the strip 110 . Another layer of adhesive connects the strip 110 to the wall of the bottle body 104 .

A third embodiment of a spray bottle 200 of the present invention is shown in FIGS. 10 and 11 . The bottle spray device 200 includes a spray head portion 202 and a bottle body 204 .

The container 210 is at least partially filled with a liquid chemical concentrate L.

In use, the bottle spray device 200 is filled with diluted chemical reagents by a bottler. Each of the four chemical containers 210 is at least partially filled with a chemical concentrate. Therefore, this particular configuration allows for four refills. Each time the filling operation is carried out, the threaded connector of the spray head portion 202 is first unscrewed from the spray bottle 204, and then the spray head portion 202 is lifted slightly until the end of the conduit 208 leaves the upper surface of the container 210. The user then forces the end of catheter 208 through one of containers 210, puncturing the container. Water may be added to the bottles 204 either before or after opening one of the chemical containers 210 .

A fourth embodiment of the bottle spray device 300 of the present invention is shown in FIGS. 12 to 14 . The bottle spray device 300 includes a spray head portion 302 and a bottle body 304 . The spray head portion 302 includes a threaded connector 306 that connects the spray head portion 302 to a threaded neck of a bottle 304 . A conduit 308 is connected to the spray head portion 302 and inserted into the bottom of the bottle 304 .

In a fourth embodiment, straps 310 and 312 connect a number of chemical containers 314 together. Five containers are used in Figure 12, however, more or fewer containers may be used.

As shown in FIGS. 13 and 14 , lines of weakness 316 are provided on the container 314 . These lines of weakness allow the container to rupture if a force is applied to the container. For example, pinching the sidewall of the bottle body 304 at a certain location on a chemical container 314 ruptures the container.

The straps 310 and 312 are preferably secured to the inner wall of the bottle body 304 . For example, strips 310 and 312 may be bonded with an adhesive, or joined by ultrasonic or thermal welding. The strip 310 and chemical container can be molded from plastic.

In this embodiment, the spray bottle 300 can be refilled by rupturing one or more containers 314 . The more containers 314 that are broken, the higher the concentration of diluted chemical that is obtained. Solvents such as water can be added before or after breaking the container. The spray bottle is preferably filled with diluted chemical by a bottler, and it contains a plurality of containers 314 so that it can be refilled multiple times.

A fifth embodiment of the bottle spray device 400 of the present invention is shown in FIGS. 15 to 17 . The bottle spray device 400 includes a spray head portion 402 and a bottle body 404 . The spray head portion 402 includes a threaded connector 406 that connects the spray head portion 402 to a bottle 404 with a threaded neck. A conduit 408 is connected to the spray head portion 402 and inserted into the bottom of the bottle 404 .

In the fifth embodiment, a plurality of annular chemical containers 410 are provided on the conduit 408 . Specifically, each annular container 410 has a central hole 412 through which the conduit 408 passes. The chemical container 410 is provided with a metal sheet 414 for sealing the upper end of the chemical container 410 containing the liquid chemical agent L, as shown in FIGS. 16 and 17 .

Typically, the spray bottle 40 is initially filled with diluted chemical formulation by the bottler and sold at the point of sale. After the user has consumed the initial diluted chemical, the spray head portion 402 can be unscrewed from the bottle body 404 and the conduit 408 can be lifted out of the bottle 404 . The user then grabs the lowermost container 410 and simply pulls it off the end of the conduit 408 before piercing the foil 414 with the tool, specifically the end of the conduit 408 . The pierced container 410 is dropped into the bottle body 410 . A solvent such as water may be added to bottle 404 before or after the step of piercing container 40 . Then, the spray head part 402 is screwed on the bottle body 404 again, and the bottle-shaped spray device 400 is reassembled.

Figure 17B shows yet another embodiment of an annular chemical container 410'. The top end of the chemical container 410' is sealed to form an annular chamber 416 containing the liquid chemical concentrate L. One or more small holes 418 are provided on the inner wall of the through hole 412', so that the chemical agent can escape through the small holes. The outer surface of the catheter seals the aperture 418 as the catheter passes through the central bore 412'. In addition, applying a layer of adhesive or sealant between the annular container and the conduit can further ensure that the hole 418 is sealed.

An insert 500 is used in a sixth embodiment of the bottle spraying device of the present invention, as shown in FIGS. 18 to 21 . The insert 500 comprises a cylindrical portion 502 with a lip 504, a connecting portion 506 connecting the cylindrical portion 502 to an upper container 508, a connecting portion 510 connecting the upper container 508 to an intermediate container 512, and a connecting middle The connecting portion 514 of the container 512 and the lower container 516 . Conduit 518 passes through hollow barrel portion 502 as shown, but is not connected to insert 500 .

The containers 508, 512, 516 are arranged in a stepped layer. The upper container 508 is narrower in width and deeper in depth than the lower container 516 . The intermediate container 512 is intermediate in size between the upper container 508 and the lower container 516 . This stepped layer structure allows the sealing film (not shown) sealing each container 508, 512, 516 to be poked with a tool while the insert remains in the bottle of the bottle spray device.

A seventh embodiment of a bottle spray device with an insert 600 according to the present invention is shown in FIGS. 22 and 23 . The insert 600 comprises a cylindrical portion 602 with a lip 604, a connecting portion 608 connecting the cylindrical portion 602 to an upper container 610, a connecting portion 612 connecting the upper container 610 to an intermediate container 614, and a connecting portion 612 connecting the intermediate container and the connecting portion 616 of the lower container 618. Each container is open at the top and bottom and is sealed with an upper foil 620 and a lower foil 622, respectively.

In use, the spray bottle is filled with diluted chemical reagent by the bottler, and the conduit passes through the barrel portion 602 only. After the user consumes the initially filled diluted chemical reagent, the catheter is drawn onto the upper container 610, and the catheter is forced through the upper foil 620 and the lower foil 622 of the container 610, and the chemically concentrated liquid is put into the bottle. middle. A solvent such as water is added to the bottle either before or after the chemically concentrated liquid is obtained. After piercing the foils 620 and 622, the catheter is lifted up and inserted between the cylindrical portion 602 and the side wall of the container 610. Alternatively, the conduit may be threaded into the container 610 , down the outside wall of the intermediate container 614 so as not to puncture the chemical container 614 . Connecting portions 608, 612, and 616 are flexible enough to act as hinges so that the lower container can be kept clear of the lower container when the catheter is inserted, preventing the lower container from being punctured.

In another embodiment, only the upper portion of each container is provided with a pierceable membrane, and the bottom of each container is molded with the container so that it is not easily punctured.

In the eighth embodiment, a mechanical connector 700 is connected to an insert 702 . The insert 702 is similar to that shown in FIG. 2 but without the lip 28 . The mechanical connector 700 includes a lip 704 and a connecting portion 706 that connects together four standoffs 708 (only two are shown in FIGS. 24 and 25 ). The connection portion 706 is connected to the upper portion of the insert 702 by press fit, adhesive, ultrasonic welding, heat welding or other suitable connection methods.

This structure is provided with four openings 710 so that when refilling a bottle spray device of this structure water flows through the openings 710 into the bottle through the central part of the mechanical connector 700 .

This configuration allows the insert 702 to be continuously extruded since no lip needs to be molded into the insert 702 . The insert 702 is provided with upper and lower sealing membranes (not shown), which are then attached to the mechanical connector 700 during assembly. Thus, the insert 702 can be cut from a long material extruded at high speed, filled with chemical concentrate, sealed at both ends with a sealing film, and then fitted with the mechanical connector 700 to complete the complete assembly.

The spraying device in the form of a bottle in the following embodiments has a chemical container and a solvent (for example, a solvent such as water) container connected to the spraying device. Solvent containers are refillable, chemical containers are refillable or non-fillable, the choice is yours. In a preferred embodiment, both the chemical container and the solvent container are located within the spray bottle.

As shown in FIG. 26, the sparging device 800 has a separate refillable solvent container 802 and a refillable chemical concentrate container 804. This configuration can be used with pump sprayers and/or pressure spray devices (ie, push button sprayers).

The refillable solvent container 802 is provided with a resealable closure such as a screw cap 806 for prefilling or refilling of solvent A. The refillable chemical container 804 is provided with a resealable closure such as a screw cap 808 for prefilling or refilling of the chemical concentrate B. Screw caps 806 and 808 can be replaced with other types of resealable closures known in the art.

A delivery tube 810 extends from the solvent container 802 and a delivery tube 812 extends from the chemical concentrate container 804 , both tubes being connected to a mixing chamber 814 . Within mixing chamber 814, chemical concentrate B is diluted with solvent A to form an effective chemical solution having a predetermined concentration of active ingredient. Then, the active solution is sprayed from the spraying device. For example, an effective chemical solution may be drawn into the pump chamber 816 and then expelled from the spray head 818 .

In the embodiment shown in FIG. 26, the inlets of delivery tubes 810 and 812 are located at the bottom of solvent container 802 and chemical concentrate container 804, respectively, so that they substantially evacuate the respective containers. However, other suitable devices, including catheters and other delivery channel structures, discussed in detail below, may be used in place of the devices shown in the figures.

In another spray apparatus 900 shown in FIG. 27, a solvent container 902 and a chemical concentrate container 904 are directly connected. Specifically, the solvent container 902 is connected to the chemical concentrate container 904 by a plastic connection web 905 . For example, solvent container 902 and chemical concentrate container 904 may be blow molded in one plastic piece. Alternatively, individual containers may be made separate from each other and joined together by internal and/or other independent fasteners.

The refillable solvent container 902 is provided with a resealable closure, such as a screw cap, for prefilling or adding solvent A during refilling. The refillable chemical container 904 is provided with a resealable closure, such as a screw cap 908, for initial filling or for adding chemical concentrate B during refilling. Screw caps 906 and 908 may be replaced by other types of resealable closures known in the art.

Another spray device 1000 is shown having a solvent container 1002 and a chemical concentrate container 1004 . The refillable solvent container 1002 is provided with a resealable closure, such as a screw cap 1006, for initial addition or refilling of solvent A. The refillable chemical container 1004 is provided with a resealable closure, such as a screw cap 1008, for initial addition or refilling of concentrate B. Screw caps 1006 and 10008 may be replaced by other types of resealable closures known in the art.

A conduit 1010 rests within the solvent container 1002 and a conduit 1012 rests within the chemical concentrate container 1004 . Both conduits 1002 and 1004 are connected to a mixing chamber 1014 . In mixing chamber 1014, chemical concentrate B is diluted with solvent A to form an effective chemical solution having a predetermined concentration of active ingredient. Then, the effective chemical solution is sprayed from the spraying device. For example, the active chemical solution can be first drawn into the pump chamber 1016 and then sprayed out of the spray head 1018 .

In some cases, it may be desirable for neither the solvent container nor the chemical concentrate container to be provided with a resealable closure, as shown in Figure 29A. Example: Disposable spray units are marketed with reduced unit shipping weight per spray unit due to the use of chemical concentrates. Alternatively, as shown in Figure 29B, only the chemical concentrate container is not provided with a resealable closure. For example, due to the toxicity and corrosive nature of the chemical concentrate, it may be desirable to completely seal the chemical concentrate container in case children are poisoned or injured by chemical spills, but this structure still allows for one or several refills of the solvent container .

Preferably, however, as shown in Figure 29C, both the solvent container and the chemical concentrate container are provided with resealable closures so that the solvent and chemical concentrate can be initially filled or subsequently refilled, respectively. This arrangement allows the spraying device to be refilled many, many times with solvent and chemical concentrate, respectively, before it is finally discarded, and is of great use in the commercial cleaning field where large quantities of cleaning chemicals are consumed.

In embodiments using conduits (as shown in Figure 28), the solvent container and chemical concentrate container may be separate tanks from each other, as shown in Figure 30A. Alternatively, the solvent container and the chemical concentrate container may be interconnected tanks, as shown in Figure 30B. Additionally, the relative sizes of the solvent container and the chemical concentrate container may vary. For example, a separate smaller chemical concentrate container can be used in conjunction with a larger solvent container, as shown in Figure 30C, or a smaller chemical concentrate container can be connected to a larger solvent container, as shown in Figure 30C. 30D. There are certain benefits to using a smaller chemical concentrate container to reduce the weight of the spray unit and limit the amount of toxic and corrosive chemical concentrate that can be contained in the spray unit. The smaller chemical concentrate container and its concentration of chemical concentrate can be selected in advance so that the solvent container is used up once it is consumed, or only part of it is used at a time of solvent consumption and the solvent container can be added one or more times.

A preferred embodiment of the spraying device of the present invention includes placing a smaller chemical concentrate container within a larger solvent container. This structure is quite safe since the chemical concentrate is placed in both the chemical concentrate container and the solvent container. Thus, it is impossible for a child playing with the device to come into direct contact with the chemical concentrate without touching the solvent container. In addition, chemical concentrate containers can be made completely airtight and substantially impermeable (eg, hermetically sealed plastic containers). Additionally, any chemical concentrate that is accidentally spilled or leaked from the chemical concentrate container is contained within the solvent container.

In the embodiment shown in Figures 31A to 31D, the chemical concentrate container can be arranged in a variety of ways. For example, the chemical concentrate container may be a self-contained tank resting within another container forming the solvent container. Alternatively, the chemical concentrate container may share one or more side walls with the solvent container, being integral with the solvent container. In addition, the chemical concentrate container can be made of a flexible material (eg, a thin flexible plastic film material).

In an embodiment of the spray device using a pump device (ie, a pump spray head in the prior art), the liquid chemical concentrate is drawn into a conduit by suction generated by the pump device in the spray head. If the chemical concentrate is contained in a hard-walled or relatively rigid-walled chemical concentrate container, the chemical concentrate container must be vented in some way so that the liquid can be drawn into the conduit, or the chemical concentrate container must be able to is pressurized to force the liquid chemical concentrate up the conduit. If the container holding the chemical concentrate has one or more flexible flexible walls or membranes (that is, is in some way collapsible), then the liquid can be drawn into the conduit without opening the vent, chemical concentrate container Depressed so that the chemical concentrate can be removed from the container.

The chemical concentrate is preferably in liquid form so that a delivery line such as a catheter can be used to take the supply of chemical concentrate. In addition, chemical concentrates may also be stored in solid, granular, aggregate, latex, vapor, and other appropriate forms. In these embodiments, the spraying means must include some means for contacting the chemical concentrate with the solvent to form an effective diluted chemical solution. The means for bringing the concentrate into contact with the solvent may have continuous, selective or intermittent functions depending on the specific construction requirements. For example, one or more accessible holes may be provided in the chemical concentrate container, or a conduit may be used to fluidly connect the solvent container and the chemical concentrate container such that the solid chemical concentrate is in continuous contact with the liquid solvent.

Fig. 32 shows yet another embodiment of the spraying device of the present invention. Spray device 1100 includes a spray bottle 1102 having a neck 1104 and an optional neck 1106 . A resealable cap 1108 is attached to the neck 1106 for prior addition of solvent A or for refilling the sprayer 1102 . A pump sprayer 1110 is attached to the neck 1104 for spraying the effective mixture of solvent A and chemical concentrate B.

The spraying device 1100 includes an adapter 1112 having a plug-like member 1114 with a radially outwardly extending flange 1116 for suspending the adapter 1112 within a neck 1104 . The size of the plug-like member 1114 is slightly smaller than the inner dimension of the bottle neck 1104 so that the adapter 1112 can be easily disassembled, especially in the spray bottle 1102 without the optional neck 1106 and resealable cap 1108. In one embodiment, it is convenient to fill the spray bottle with solvent. Also, on the contrary, the size of the plug 1114 can be made slightly larger than the inner size of the diameter portion 1104, thereby preventing movement of the plug 1114, thereby preventing children from accessing the chemical concentrate B. In addition, the plug may be adhesively bonded or otherwise connected, for example, by welding or welding, so that the plug 1114 cannot be removed without destroying the plug 1114 and/or the spray bottle 1102 . In embodiments where the plug 1114 is directly attached to the spray bottle 1102, the flange 1116 can be eliminated because the flange 1116 is no longer required to suspend the plug 1114.

A plug-like extension 1118 extending downwards is disposed on the plug-like member 1114 . The plug-like extension 1118 is connected to a container 1120 containing the chemical concentrate B. For example, the plug-like extension and container 1120 may be connected by a press fit between the outer dimensions of the plug-like extension and the inner dimensions of the upper portion of the container 1120 . Alternatively, the container 1120 and the plug-like extension 1114 may be connected by other suitable methods, such as screwing, bonding, welding, welding, mechanical fasteners, etc., which provide detachable or non-detachable connections.

The more suitable shape of the container 1120 is a test tube-shaped container, as shown in FIG. 32, which has a cylindrical body with a semicircular end. The test tube container 1120 can be made of glass which has excellent chemical resistance, however, to prevent the container from being accidentally broken, a plastic container is more suitable. In addition, other suitable shapes and sizes can be used instead of the test tube-shaped container 1120 . The larger the container 1120, the more chemical concentrate can be stored in the spray device 1102, but encroaching on additional space for solvent A in the spray device 1102 of the same size.

Conduit 1122 rests within container 1120 so that chemical concentrate can be drawn through conduit 1122 into plug adapter 1112 to mix with solvent A. Additionally conduit 1124 is inserted into spray bottle 1102 so that solvent A can be drawn through conduit 1124 into plug adapter 112 to mix with chemical concentrate B.

The plug adapter 1112 has a tubular extension 1126 connected to the spray head 1110 . For example, the plug adapter can be a plastic injection molded part and the tubular extension 1126 can be shaped and sized as prior art conduits so that they can be inserted into the existing conduit interface of an existing spray head, and in addition Alternatively, other suitable plastic tubular delivery tube devices may be used to fluidly connect the adapter 1114 and the spray head 1110 instead of the aforementioned tubular extension.

The specific structure of the preferred adapter 1112 is shown in Figures 34 and 35 and described in detail below. Adapter 1112 is assembled from four separate components: an upper member 1128 , a lower member 1130 , a float 1132 and a float 1134 , the assembly of which is shown in FIG. 34 .

Upper member 1128 and lower member 1130 are preferably formed by plastic injection molding into the shape shown. The upper member 1130 includes a barrel portion 1132 connecting the upper flange portion 1116a and the lower disc portion 1136 . Tubular extension 1126 extends upwardly from lower disk portion 1136 to form fluid passage 1138 through upper member 1130 .

A tubular extension 1140 with a fluid passage 1142 is supported on the underside of the lower disk portion by a plurality of spaced support members 1146 . For example, the supports 1146 spaced apart from each other may be arranged 90° apart from each other to form four liquid passages or openings (eg, cage structures) therebetween. The lower portion of the tubular extension 1140 is provided with a funnel-shaped channel portion 1148 .

The lower member 1130 includes a barrel portion 1150 connecting an upper flange portion 1116 and a lower disc portion 1152 . The barrel 1150 is also provided with a lower flange portion 1154 having an upper surface portion 1154a against which the bottom of the upper member 1128 rests. Specifically, upper surface portion 1154a of lower flange portion 1154 acts as a stop to limit the extent to which upper member 1128 nests within lower member 1130 . In addition, a plug-shaped extension is provided at the bottom of the lower member for connecting with the above-mentioned container 1120 .

A mixing chamber MC is formed between the lower surface of the lower disc portion 1136 of the upper member 1128 and the upper surface 1152a of the lower disc portion 1152 of the lower member 1130 . The height of the lower flange portion 1154 of the lower member 1130 constitutes the height of the mixing chamber MC. Mixing chamber MC is fluidly connected to channels 1138 and 1142 of upper member 1128 .

The lower member 1130 is provided with a fluid channel 1156 comprising a lower channel portion 1156a, a funnel-shaped channel portion 1156b, and an upper channel portion 1156c. The lower channel portion 1156a is sized for a press fit connection with the upper portion of the conduit 1124 (as shown in FIG. 35). In addition, the upper channel portion 1156c can be made into a size that can accommodate the floating ball 1132, and the funnel-shaped channel portion 1156b upwardly supports the floating ball 1132 to form a one-way valve, so that only the liquid solvent A is allowed to flow upward along the conduit 1124 into the mixing chamber MC, The mixed liquid is not allowed to flow back into the spray bottle 1102 along the conduit 1124 through the one-way valve. Optionally, a spring 1132a can be used to bias the float 1132 against the surface of the funnel-shaped channel portion 1156b to further ensure that the mixed liquid does not leak from the mixing chamber MC into the conduit 1124 . One end of the spring 1132a presses against the curved surface of the floating ball 1132 , while the other end is located in an annular groove 1132b at the bottom of the barrel 1150 . This structure secures the end of spring 1132a to maintain its orientation during operation. Other types of springs or biasing devices may be substituted for the spring 1132b described above (eg, cantilever springs).

The lower member 1128 also has a tubular extension 1158 with a fluid passage 1160 therein. The liquid passage 1160 includes a lower liquid passage portion 1160a, a funnel-shaped liquid passage portion 1160b, and an upper liquid passage portion 1160c. Lower channel portion 1160a is sized to form a press fit connection with the upper portion of conduit 1112 (see FIG. 35). In addition, the upper channel portion 1160c is sized to accommodate the float 1134, and the funnel shaped channel portion 1160b supports the float 1134 upwardly, forming a one-way valve to allow only the chemical concentrate B to flow up the conduit into the mixing chamber. chamber MC without allowing the mixed liquid in the mixing chamber MC to flow down into the container 1120 through the conduit 1112 along the one-way valve. In addition, when the floating ball 1134 moves upwards, the funnel-shaped passage portion 1148 of the tubular extension 1140 covers the floating ball 1134 like a cup, and stops its upward movement, that is, constitutes a check valve with the opposite working direction of the lower one-way valve. to the valve.

The two one-way valves of tubular extension 1158 form a metering valve. Specifically, the height H over which the float 1134 travels forms a metering chamber C having a fixed volume for metering the amount of liquid chemical concentrate flowing into the mixing chamber MC. Additionally, the float ball 1134 is sized smaller than the inner diameter of the lower liquid passage 1160 so that liquid can flow around the ball 1134 during metering as discussed below.

In FIG. 35 , upper member 1128 is separated from lower member 1130 . In the assembled adapter 112, the upper member 1128 and the lower member 1130 are connected together. For example, flange portions 1116a and 1116b may be glued or welded together for assembly. In summary, there must be a tight connection between the upper member 1128 and the lower member 1130 in order to seal the mixing chamber MC.

The plug-shaped adapter 1112 must be provided with an air channel to connect the air space between the adapter 1112 and the spray head 1110 and the air space in the spray bottle 1102 and the container 1120, so that the air from the spray bottle 1102 and the container 1120 is respectively When liquid solvent A and liquid chemical concentrate B are drawn, air is added thereto to fill the lost liquid volume, however, if container 1120 is a container with flexible or relatively flexible walls, for example, a collapsible container (e.g., like balloon container), then there is no need for an air passage leading to the container 1120.

Air channels 1162 may be provided along the sidewall of the plug adapter 1112 . For example, a groove is formed along the side wall of the lower member 1130, and the flange 1116 has a hole communicating with the groove. This structure provides an air passage to the spray bottle 1102 . The groove can extend down the plug-type extension 1118 to provide an air passage to the container 1120 containing the chemical concentrate B.

In another embodiment, the one-way valve can also be removed or the position of the one-way valve can be changed to prevent contamination of the liquid solvent A and the liquid chemical concentrate B. For example, a single one-way valve can be provided in the liquid channel 1138, however, this structure still allows the working liquid in the mixing chamber MC to contact the liquid solvent A and the liquid chemical concentrate B. In addition, other suitable metering devices can also be designed and adopted instead of the above-mentioned illustrated structures.

Alternatively, a valve may be provided on the plug adapter 1112 for controlling (eg, opening and closing) the passage of fluid to or through the fluid passage 1138 . This further prevents misuse, and/or prevents leakage of mixed chemical liquid from mixing chamber MC.

In use, after the conduits 1112 and 1124 and the mixing chamber MC are installed, the spray head 1110 (see 32) is used to draw liquid upwards from the mixing chamber MC so that the liquid passes through the spaced-apart openings formed by the supports 1146 and enters the liquid upwardly. Channel 1138 supplies spray head 1110 with an effective liquid mixture of the appropriate concentration for the active ingredient.

When liquid is drawn from mixing chamber MC, float 1132, which constitutes a one-way valve, moves upwards, causing liquid solvent A to be drawn into mixing chamber MC through conduit 1124 and channel 1156. At the same time, the float 1134 constituting a metering valve moves upwards, so that the chemical concentrate on the float 1134 flows upwards into the mixing chamber MC. The floating ball 1134 moves upward, and the chemical concentrate located at the bottom of the floating ball 1134 is sucked up into the metering chamber along the conduit 1112 , and the above-mentioned action continues until the floating ball 1134 is blocked by the funnel-shaped liquid channel 1148 . At the end of each spray cycle (i.e., when the pump lever is fully retracted), the spray head releases the drawn liquid back into the mixing chamber MC, at which point the float 1134 moves downward due to gravity, allowing the liquid chemical concentrate to Flows on the outside of the float and refills the metering chamber during the next spray cycle.

The liquid solvent and liquid chemical concentrate entering the mixing chamber are completely free to mix before the liquid solvent A and liquid chemical concentrate B pass upward through the liquid channel 1138 into the spray head 1110 . In addition, because the inlet positions of the liquid solvent and the liquid chemical concentrate are not together, and because the cage structure of the support members 1146 spaced apart from each other in the mixing chamber MC separates the liquid openings into the liquid channel 1138 from each other, there is The stirring action enhances the mixing of liquids in the mixing chamber.

When sparging device 1100 is not used, it is impossible for active chemical reagents in the mixing chamber to flow down conduits 1124 and 1112 because floats 1132, 1134 respectively form one-way valves. This prevents solvent A in the spray bottle and chemical concentrate B in container 1120 from contaminating the active liquid from mixing chamber MC.

From time to time, the liquid chemical concentrate on the float 1134 in the metering chamber will somehow mix with the active liquid in the mixing chamber. However, after one or two sprays, the metering valve will supply only a fixed amount of liquid chemical concentrate to the mixing chamber as described above.

As shown in FIG. 38, another adapter 1200 converts an existing spray bottle with only one neck into a spray bottle with two necks. Specifically, adapter 1200 includes an adapter body having a fluid channel 1204 connected to a fluid channel 1206 . The adapter body 1202 has an internally threaded nut 1208 . The nut 1208 can be integrally formed with the adapter body 1202, or it can be a separate piece rotatably connected to the adapter body. The adapter body 1202 and nut 1208 may be connected in the same or similar manner as the threaded nut of an existing spray head and the body of an existing spray head so that they are relatively rotatable and sealed together. This configuration allows the adapter to be variably oriented relative to the spray bottle to which it is attached.

An internally threaded nut 1208 is attached to the externally threaded neck of an existing single-neck spray bottle. The main body 1202 of the adapter is provided with a first neck 1210 with external threads, which is used to connect with the nut with internal threads of the existing spray head. The adapter body 1202 also has a second externally threaded neck 1212 onto which a reusable internally threaded nut 1214 can be fitted. Additionally, the adapter body 1202 may also be provided with other types of secondary releasable closure means (eg, threaded plug, internally threaded neck, twist-to-open valve, shut-off stopcock, etc.).
