Description

liquid container

technical field

The present invention relates to the invention of the liquid container, specifically relates to the invention of the liquid container such as the cleaning liquid container of filling cleaning liquid used in medical institutions such as hospitals, health care stations.

Background technique

In medical institutions such as hospitals and health care stations, cleaning solutions such as physiological saline, water for injection, distilled water, and disinfectant for cleaning surgical instruments and sick parts of patients are used. Such cleaning liquids are sealed in bag-type and bottle-type cleaning liquid containers, and two forms of small-diameter openings and large-diameter openings are generally used.

Among these two types, the small-diameter open container is suitable for fine cleaning such as cleaning of small wounds of patients, partial cleaning of wounds, or partial cleaning of medical instruments, and is also suitable for cases where blowing and wiping are necessary.

In addition, the large-diameter container is suitable for cases where a large amount of cleaning fluid is required each time, for example, for cleaning the entire wound part of a patient and the entire medical instrument.

However, with such a conventional cleaning solution container, two types must be stored according to the usage, which not only requires a large storage space, but also requires separate inventory management, which is very troublesome.

For this reason, the scheme of the container for cleaning has been proposed. On the cover of the opening part of the sealed container main body, the sealing film part is connected and set through a large-caliber cutting part, and a pull ring for cutting and unsealing is set at the sealing film part, and the sealing film part is set at the same time. The film part is provided with a twisted part protruding upward, and the twisted part can be twisted to form a small-diameter opening part by twisting and pulling off the part (refer to Registered Utility Model No. 3009864).

The cover of the cleaning container can utilize the stretching of the pull ring due to twisting and taking off the part, and the opening part of any one of the small-diameter opening and the large-diameter opening can be selected to be formed. One kind of cleaning container is enough for storage. Inventory management is easy while reducing storage space.

But because the size (inner diameter of the ring) of the pull ring (stretch ring) of the described cleaning container is fixed, it is very difficult for people whose fingers are not suitable in size to use it. The pull tab is pulled up from a narrow space, and the operability is poor. In addition, both the pull ring and the detachment part shrink in diameter during molding, and it is difficult to mold, so it cannot be said to be easy to mold.

Therefore, one of the main objects of the present invention is to provide a liquid container having a simplified structure, easy molding, and easy operation of forming an opening.

Another main object of the present invention is to provide an easy-to-handle liquid container in which small-diameter and large-diameter opening portions are selectively formed.

Contents of the invention

The liquid container provided by the present invention is characterized in that it is composed of a container body with an opening and containing liquid, and a cover that seals the container body. The cover can be installed around the opening of the container body, and the cover with the first opening The main body, the cavity, and the flange that connects the lower end of the cavity with the first opening of the cover body through the first connecting part, and the first connecting part is weakened by applying force to the cavity , can be disconnected.

That is, the liquid container of the present invention has a very simple structure and the first opening can be formed by simple operations because the first connecting portion is weakened and can be disconnected by applying a force to the cavity. In detail, for example, the cover can be obtained by one injection molding of 3 molds consisting of a pair of left and right outer molds and an inner mold pressed in from the bottom, without shrinkage, and easy mold ejection. In addition, since the opening (first opening portion) can be formed by laterally pulling down instead of stretching operation (pull), for example, by applying force to the cavity, the operation is simple.

The cavity and the flange of the present invention have reinforcing ribs integrally formed therewith, and the reinforcing ribs extend from the lower part of the circumferential surface of the cavity along the upper surface of the flange to the vicinity of the first connecting part (weakened part) with the cover main body It is beneficial to apply a force to the cavity, for example, to use a lateral pull-down operation to disconnect the first connection between the flange and the cover body, so that even if the diameter of the first opening is large, the force of the lateral pull-down cavity is along the It is suitable because the reinforcing rib is transferred to the corresponding part of the first connecting part in a concentrated manner, and the first opening part can be easily opened.

The cavity of the liquid container of the present invention has a second opening whose diameter is smaller than the first opening of the cover main body at the top, and the cavity main body that connects the periphery of the lower end with the first opening part of the cover main body through the flange, and passes through the second opening of the cover main body. 2. The top part of the connection part and the 2nd opening part are integrally formed; the 2nd connection part is weakened by applying force to the top part and can be disconnected, while the 1st connection part is weakened by at least applying force to the cavity body, That is, applying force to both the main body and the top of the cavity, or only applying force to the cavity can be disconnected, and a small-diameter opening (second opening) can be formed by applying force to the top, and a small-diameter opening (second opening) can be formed by applying force to the main body of the cavity. Large-diameter opening portion (first opening portion) and liquid container, especially cap, are easy to form, because it is possible to use injection molding method without difficult die-cutting.

Wherein, for the first connecting part, it is said that the first connecting part can be broken by applying force to the cavity to make it weak, which means that in the state of holding the cover main body, the first connecting part can be disconnected by applying a force relative to the cavity, so that the For openings with desired diameters, the mechanical strength of other parts is weakened by thinning the wall of the first connecting part, or making a V-shaped cross-sectional groove, sewing machine needle-shaped cutting line, etc. In addition, for the second connecting part, the so-called weakening of the second connecting part by applying a force to the top can be broken, which means that the second connecting part can be disconnected by applying a force relative to the top, such as using Turning off the operation of the rotational force around the shaft can form an opening with a desired diameter, which is the same as the above case, and weakens the mechanical strength. Butterfly wing shape can be exemplified as the top that is suitable for applying such a rotating force around the axis, so that the opening direction of the butterfly wing is at a right angle to the transverse direction of the cavity. In addition, the thickness of the second connecting portion is preferably the same as or smaller than that of the first connecting portion. Of course, both the first connection part and the second connection part need to have the force that is received when the liquid container is usually used (usually when it is subjected to pressure or impact or contact during proper production, placement, handover, etc.) mechanical strength. In addition, when stacking and transporting trucks and other vehicles, it is presumed that there is a possibility that an unnecessary opening will be formed on the cover due to an unpredictable force. It will affect the inner cover.

The cover body is installed on the circumference of the opening part of the container body, specifically, the lower end circumference surface of the cover is welded or bonded to the upper end circumference surface of the opening part of the container body, or when the opening of the container body protrudes in a cylindrical shape, Embedding the main body of the cap on the outside or inside of the opening, that is, by embedding, fusion welding, or bonding, the main body of the cap is easily mounted on the opening of the container main body.

From another point of view, the liquid container that the present invention can provide is characterized in that it is composed of a container body with an opening, a liquid contained in the container body, and a cover that seals the opening of the container body, and the cover can be installed in the container body opening. surrounding, and consists of the main body of the cover with the first opening, the cavity, and the flange that connects the lower end of the cavity with the first opening of the cover main body through the first connecting part, and through the cavity The application of force weakens this first connecting portion, allowing it to be disconnected.

From another point of view, the feature of the liquid container that the present invention can provide is: a liquid container cover for sealing the opening part of the liquid container body, this cover can be installed around the opening part of the container body, and the cover with the first opening The main body, the cavity, and the flange that connects the lower end of the cavity with the first opening of the cover body through the first connecting part, and the first connecting part is weakened by applying force to the cavity , can be disconnected. A general-purpose cap can be used to seal the opening portion of the container main body in various forms (for example, liquid containers of different capacities).

Detailed ways

The present invention will be described in detail below in conjunction with various implementations shown in the figures. However, the present invention is not limited thereto.

Fig. 1 is a front view showing an embodiment of a liquid container of the present invention, Fig. 2 is an enlarged sectional view of main parts of Fig. 1 , Fig. 3 is an enlarged sectional view of main parts different from Fig. 2 , and Fig. 4 shows a state where a cover is removed Fig. 5 is a perspective view of the main part of Fig. 4 from the direction of arrow A in Fig. 4, Fig. 6 is a top view of Fig. 5, and Fig. 7 is a front view of the cover cover in Fig. 1 .

At first in Fig. 1～3, as the cleaning solution bottle 1 of liquid container, mainly by the bottle main body 2 that is housed as the physiological saline of cleaning solution or water for injection (omitted in the figure), be fixed on this bottle main body opening part 3 and seal the opening The cover 4 of part 3 and the cover cover 5 of another part that can be assembled and disassembled with this cover constitute.

The bottle body 2 is a box-shaped bottle (container) obtained by blow molding of polypropylene resin. After injecting physiological saline or water for injection (approximately 100 ml) from its opening 3, the cap 4 described later is bonded to the opening. The upper peripheral surface of the part 3 is integrally sealed with its lower peripheral surface, that is, the lower flange 6 .

The cover 4 is integrally formed by blow molding of polypropylene resin (for example, thickness: average 1.0 mm). Especially in FIGS. The cavity 8 formed on this cover main body and the flange 9 that makes the outer peripheral edge below the cavity and the first opening portion 19 of the cover main body 7 integrally constitute. The first opening 19 of 7 is small, the second opening 20 is small, and the peripheral edge of the lower end is connected with the first opening 19 of the cover main body 7 through the flange 9. The main body 8a of the cavity is formed on this cavity main body. The top portion 8b on the upper portion of the second opening 20 is formed. In addition, a matching bar-shaped protrusion 17 is formed on the inner circumferential surface of the cover housing 5, and a groove 18 is formed on the outer circumferential surface of the cover main body 7. .

The flange 9 has a thin-walled head 10 (for example, a V-shaped section groove bottom thickness of about 0.4mm) that is connected to the first opening portion 19 of the cover main body 7 and forms a large-diameter opening, and the cavity 8 and the flange 9 have From a portion of the lower circumferential surface of the cavity 8 along the flange upper surface in a reflection direction to the rib 21 near the thin-walled head 10, only force is applied to the cavity 8, that is, when the thin-walled head is knocked down laterally, the thin-walled head The part 10 can be broken off (the thin-walled head part 10 cannot be broken even if the detachment part 13 described later is twisted), so that a large-diameter opening part (diameter: about 18mm) can be formed.

The top 8b has a thin-walled head 12 (for example, a V-shaped cross-sectional groove bottom thickness of about 0.4 mm) forming a small-diameter opening as a second connection portion on the second opening portion 20 of the cavity 8, and the thin-walled head portion Butterfly wing-shaped part 13, if force is applied to the part 13, that is, if it is twisted, only the thin-walled head 12 can be twisted off (the thin-walled head 10 is unscrewed), so that a small diameter can be formed. Opening part (diameter: about 6mm).

As mentioned above, if the cleaning liquid bottle 1 carries out the operation of knocking down the chamber body 8 horizontally, a large-diameter opening can be formed easily, and the cleaning liquid can be poured out from this large-diameter opening at once, which can provide protection for the entire wound part and the entire wound of the patient. Cleaning of medical equipment, etc. On the other hand, if the operation of taking off the part 13 is twisted, only the small-diameter opening can be formed, and the cleaning solution can be poured out a little from this small-diameter opening, so that the cleaning of the patient's small trauma part and part trauma part etc. can be provided.

The main reason is that the cleaning liquid bottle 1 can choose a small-caliber opening or a large-caliber opening according to needs, so that a bottle of one size can be used for two purposes, and only one kind of liquid container is enough for storage, which can reduce the storage space and at the same time Inventory management is easy, too.

The cleaning solution bottle 1, especially the cap 4 of the cleaning solution bottle can be formed (molded) by spray molding, so the forming is easy. For example, the cover can be obtained by injection molding of 3 molds consisting of a pair of outer molds on the left and right and an inner mold pressed in from the bottom. It does not require difficult mold ejection and is easy to form. In addition, for container bodies of other sizes (such as capacity 200ml, 500ml, 1000ml) openings can also use a universal cap. Have the cleaning solution bottle 1 to utilize the cavity 8 (the main body 8a of the cavity) of cover 4 and the operation method that takes off part 13 differently again, can make the 1st, the 2nd connecting part (thin-walled head 10, 12) Disconnection, since small-diameter openings and large-diameter openings can be selected, the operation is easy to distinguish.

Unlike the above-described embodiments, a liquid bag (bag) may be used in which the container body of the liquid container is made of a flexible sheet. In addition, like the above-described embodiment, the inner peripheral surface of the cover has protrusions or grooves, and the outer peripheral surface of the main body of the cover has protrusions or grooves that can be assembled and disassembled (hopefully can seal liquid) The matching groove or the matching protrusion can also be assembled and disassembled at the opening of the container body or near the opening. It is also possible to form a liquid-tight fit or a screw fit between the cover cover and the container main body or the cover main body. For example, it is also possible to form threads on the inner peripheral surface of the cover housing, and form thread grooves on the outer peripheral surface of the cover main body to cooperate with the threaded screws of the cover housing. The liquid contained in the liquid container can also be cleaning solutions such as distilled water, disinfectant (such as ethanol for disinfection), or neutral water or contact lens cleaning solutions.

There is not only one reinforcing rib arranged on the cavity body and the flange, but more than two. In the case where these ribs are provided in different directions, openings can be formed by applying force from various directions. For example, with the cavity as the center, in the case of a certain direction (0-degree direction) and a 90-degree direction (90-degree direction) with reinforcing ribs, it is possible to apply force (operation) from the 0-degree direction. The opening is formed, and the opening can also be formed when a force is applied (operated) from a 90-degree direction.

According to this invention, since the first connecting portion between the flange and the cover body is made into a fragile structure by applying force to the cavity, it can be disconnected, the structure is very simple, and the first opening can be formed by simple operations.

The cavity and the flange of the present invention have reinforcing ribs integrally formed therewith, and the reinforcing ribs extend from the lower peripheral surface of the cavity along the upper surface of the flange to the vicinity of the weakened part with the main body of the cover, which is beneficial to The first connecting part between the flange and the cover body is disconnected by applying force to the cavity, so that even if the diameter of the first opening increases, the force of laterally knocking down the cavity is concentrated and transmitted to the first connecting part along the rib It is easy to open the corresponding part of the first opening.
