Description

DILUTION SYSTEM FOR FILLING SPRAYING BOTTLES FIELD OF THE INVENTION This invention relates to an apparatus for diluting a liquid concentrate with a diluent to form a liquid dilute use solution. The invention also relates to a station comprising one or more such apparatuses, each apparatus dedicated to a single liquid concentrate and to a diluted use solution. Together with the apparatus, the liquid concentrate is packed in a container adapted for use in the apparatus. The container has closing means that can be opened through opening means in the appliance, when inserted in a tank of the appliance. The invention also relates to the concentrate container which, after being emptied, can be used as a container for diluted use solution. The concentrate container may comprise closure means to prevent spillage of the concentrate from the container during storage, shipping, etc. The closure means may comprise a flexible closure band or a rigid closure device. Each use solution container comprises a unique matching surface that permits the use of the container only with an appliance container having a matching surface that coincides with the matched surface of the container. The dilution apparatus is adapted for use with aqueous dispersions, aqueous reduction concentrates, or aqueous-alcoholic concentrates, which can typically be diluted with service water to dilute useful solutions in typical institutional or industrial applications. The invention also relates to methods for using the apparatus.

BACKGROUND OF THE INVENTION The dilution apparatus that uses a vacuum cleaner to dilute a liquid concentrate with a liquid diluent to form a solution of use, has been used for many years. The first of such systems was loose pipe assemblies, for a particular purpose, connections, vacuum cleaner, etc. The typical dilution station of the prior art comprises a large reservoir of a concentrate container which is large in volume when compared to a use solution container. The concentrate container typically contains more than 5 liters of concentrate, while the container for the diluted use solution is typically relatively small, typically from 500 milliliters to about 3 liters. The concentrate container may comprise a plastic loading container of 5 to 10 liters, a drum of 208.12 liters or a container of similar volume. The solution container for typical use is a bucket, bucket for mopping, spray bottle, etc. Said dilution apparatus is operated by passing service water or other aqueous stream through the aspirator containing a venturi tube. The venturi tube expels the liquid concentrate from the volume to contact the stream of aqueous diluent, mixes the diluent and the concentrate forming a use solution, which is then transferred to a container of use solution. The configuration of said dilution apparatus has taken an enormous variety of modalities. In the past, a large number of types of concentrate containers, transfer mechanisms, aspirating control means, use solution containers and various combinations of these elements have been tried. A prior art dilution station is the DEMA mixing center dilution system which is designed to a concentrate of bucket container proportion typically of 18.92 liters to a mop bucket. In this application, the mop bucket is a substantially different container than the concentrate container. Twichell et al., Patent of E. U.A. No. 1, 691, 171, teaches an assortment device for a soda fountain. The dispenser includes a container with a ladle or bucket to empty the syrup to carbonated water. The resulting soda is released through a spout and into the glass or jar of users. Muller and others, patent of E. U.A. No. 3, 443, 726 shows a mixing and assortment container in which a first container of smaller concentrate, after coinciding with a dilution container, opens the concentrate for the liquid towards the container of use solution. The concentrate is assorted to a diluent present in the container. The matching containers are stirred to mix the diluted use solution. Crumby, patent of E. U.A. 4, 741, 368, shows returnable containers for liquid chemicals having a concentrate drum source, an intermediate container and supply means to a spray applicator. Bavaveas, patent of E. U.A. No. 4,950,083, teaches a package adapted for the use solution, made of a liquid concentrate. The package contains means to measure the concentrate to enter the container for dilution. Schmidt, patent of E. U.A. No. 4,874, 1 13, shows a dispensing station for two or more cosmetic dispensers. Each dispenser having a container with a removable top for the introduction of liquid cosmetic material. These dispensers do not dilute a concentrate, but supply a pre-made lotion or gel. Bally, patent of E. U.A. No. 5, 037,003 teaches a dilution station having a large concentrate container and dilution means in a frame containing an apparatus that prevents the undesired operation of dilution valves. Conté, patent of E. U.A. No. 5,351, 892, shows a multipurpose unitary jet and dilution, which directs a concentrate selected from a charge to a spray head. The device allows the selection of one of many specific concentrates for the assortment. Spriggs et al., Patent of E. U.A. No. 5,259,557, shows a system of proportion and assortment of solution that can dilute a product from a container of liquid concentrate to a smaller separate tank or to a bucket of molasses or another bucket. The manually operated aspirator can have an individual dilution ratio. The diluted material stored in an intermediate container can be supplied to use bottles equipped with spray heads. Dyer, WO 94/24040, teaches a gravity feed assortment system, in which fluid is dispensed from a bottle to a spout assembly. A valve on the bottle can be moved from an open position to a closed position to allow fluid assortment. In large part, the prior art dilution systems involve relatively large containers for concentrate, when compared to diluted use solution containers that require different sized containers for the concentrate and diluted use solution. The prior art discloses systems comprising a concentrate container that is different from a use solution container. These systems require a great invention of different containers. Furthermore, the prior art systems do not ensure the introduction of the appropriate concentrate into the concentrate container, where multiple concentrate containers are used by a dilution station.

Accordingly, there is a substantial need for a new versatile dilution apparatus and new dilution stations having one or more dilution apparatuses. These stations will ideally allow the reuse of the concentrate container as a diluted use solution container, reduce container stocks, reduce accidental mixing of concentrates, ensure proper dilution and filling of use solution containers and can easily be operated by maintenance personnel.

BRIEF DISCUSSION OF THE INVENTION The invention resides in a dilution apparatus and a dilution station comprising one or more of the dilution apparatuses optionally combined with other useful features. The dilution apparatus is configured to dilute a liquid concentrate, commonly an aqueous liquid concentrate with a liquid diluent such as service water, deionized water, soft water, hot water and other aqueous streams to form a solution of use. The diluent passes through a vacuum cleaner that contains an inlet for the liquid concentrate and a separate inlet for the liquid diluent. The aspirator also contains an outlet for the solution of use formed by the action of the venturi tube of the aspirator together with the diluent and the concentrate. The liquid concentrate is maintained within a reservoir that has a sufficient volume to allow convenient operation. The reservoir contains a liquid concentrate outlet that is directed, in fluid communication, to the intake of the aspirator for the liquid concentrate. The reservoir also contains media to open a container of liquid concentrate. The reservoir is formed and configured to allow the insertion of the concentrate container. The reservoir is preferably formed and configured to coincide with the concentrate container, so that other containers can not be inserted in such a way that the container opening means can actively open the container. The container of liquid concentrate is closed by means of closure. The closure means may comprise a flexible closure band or rigid cylindrical closure equipment. Both the equipment and the flexible band are designed to allow easy puncture of the band to allow drainage or transfer of concentrate material to the reservoir. The closing device has an easy opening accessory. Preferably, the liquid concentrate container is inserted into the tank in an arrangement, so that, after opening, the concentrate flows into the tank. The mechanical force involved in inserting the container drives the container against the means to open the container resulting in opening equipment. The liquid concentrate is transferred from the open container through the opening equipment, to the tank. When a volume of diluted use solution is desired, a mechanical, electrical or hydraulic controller is activated, so that a measured volume of diluent passes through the aspirator venturi tube by passing or extracting an appropriate amount of diluent and liquid concentrate from the deposit, mixing the concentrate with the diluent. The resulting use solution is collected in a container of use solution placed in a container port. The use solution container and the concentrate container, used together with the dilution apparatus, are substantially identical. The equipment is preferably configured so that the concentrate container, when empty, can be inserted into a filling station in the dilution apparatus without physical modification of the container or interference with the dilution station. Alternatively, if desired, the equipment can be removed from the concentrate container before use. The container for the diluted solution can also be returned to a concentrate source, fill with concentrate and equip with a new equipment, resulting in the creation of a new concentrate container. In a preferred mode of operation of the dilution apparatus of the invention, the dilution apparatus comprises a container port or container filling station for use solution comprising a defined space in the apparatus. The defined space, preferably depressed, is configured to allow the insertion of a use solution container. The space is configured to support the use solution container and maintain its position during filling. As such, the space comprises a base portion and wall portions that are configured to surround and contain the use solution container. Substantially increased dimensions of the use solution container could prevent insertion of the container to the filling station. Said filling station may have the outlet of the aspirator positioned near the upper portion of the use solution container. The suction outlet can contain a flexible filling tube that allows the insertion of the filling tube into the container before the installation of the container in the filling station.

Figure 1 shows the liquid concentrate container and the use solution container which are substantially identical. Figure 2 is a top view of the equipment used to seal the container for the liquid concentrate. The opening is defined by a hinge area and a fracture zone is shown to open the container of liquid concentrate. The fracture zone, when perforated through means to open the equipment, in the reservoir of the apparatus, leaves an opening that allows the concentrate to flow to the reservoir from the container.

The matching surface is adapted to the shape of the appropriate concentrate container, and contains a perforating device that opens the equipment to ensure that the concentrate is transferred from the concentrate container to the reservoir. Figure 6 is a view of a double function dilute use concentrate / container container. Fig. 7 is a general side view of a dilution apparatus substantially identical to Fig. 1, except that the apparatus of Fig. 7 uses a hydraulic-magnetic switch to operate the vacuum cleaner 15. Fig. 8 is a cross-sectional view of an embodiment of a matching lid, bottle and equipment of the concentrate / dilution use container of the invention. The equipment contains a venturi tube comprising a hole and a flexible hydrophobic band. The bottle and the equipment are closed with a ventilated lid that has a ventilation that allows trapped vapors or gas to leave the container without developing an undesirable pressure.

DETAILED DISCUSSION OF THE INVENTION The apparatus of the invention for diluting a concentrate to a diluted liquid use solution contains a vacuum cleaner. The aspirators contain a venturi device driven by water pressure to eject a concentrate. The venturi device comprises a nozzle opening associated with a concentrate solution body. The speed of the diluent through the nozzle causes a reduction in pressure, ejecting the concentrate towards the vacuum cleaner, generally causing a mixture of the concentrate and diluent typically at a fixed ratio depending on the pressure, pipe sizes and length. Once diluted and mixed, the diluted use solution leaves the vacuum cleaner through an outlet for the diluted use solution. The output is in liquid communication with the use solution container. The aspirator is typically sized and adapted to the diluent pressure ranging from about 69 to about 414 KPa. Preferably, service water is available in most municipalities at a pressure of approximately 138 to 276 KPa. The apparatus of this invention works best at said pressure. However, the apparatus can be adapted for a variety of water pressures. The apparatus is preferably assembled using components that allow a flow of diluent through the apparatus of about 3 to 20 liters per minute. Typical operation of the dilation apparatus typically results in the creation of more than about 3 to 20 liters per minute of diluted use solution per minute. The concentrate materials of the invention include general purpose cleaning and sterilization materials, coating compositions, and other useful institutional or industrial liquid concentrates. Such materials include window cleaners, hand soap, hard surface cleaners, floor cleaners, sink cleaners, tile cleaners, drain cleaners and drain openers, glass cleaners, cleaners for food preparation units, sterilizers , disinfectants, aqueous coating compositions, concentrates that are reduced with water, floor finishes that are reduced with water, aqueous wax dispersions, air fresheners, odor counteractants, and other similar concentrates that can be formed as an aqueous solution, an aqueous alcohol solution, an aqueous dispersion, an aqueous reduction solution or dispersion, etc. The liquid concentrate materials useful for dilution to a diluted use solution typically comprise aqueous solutions, aqueous suspensions, aqueous reduction concentrates, aqueous alcohol concentrates, etc. , of chemical products for cleaning or sterilization. The concentrate may contain from about 20 to 90% by weight of active cleaning materials. The typical viscosity of liquid concentrates typically varies from about 1 to 400 cP. Chemical systems may comprise a surfactant-based cleaner, an antimicrobial, a floor finish, etc. The cleaner can be a generally neutral system, an acid-based system containing compatible surfactant, cosolvents and other additives or alkaline systems containing a source of alkalinity, compatible surfactants, co-solvents, etc. Generally, neutral surfactant-based systems are commonly based on an aqueous or aqueous / alcoholic solvent system and can use a variety of surfactants, thickeners, builders, builders, dyes, fragrances, etc. , to form the compositions of the invention.

These materials can be used in combination with compatible surface-active agent systems, thickeners, builders, dyes, co-solvents, well-known, etc. , to form a fully functional material. Alkaline systems are commonly aqueous or aqueous solvent systems combined with a source of alkalinity. Highly alkaline and moderately alkaline sources can be used. Useful alkaline sources include metal alkalis, organic bases, ammonium hydrates, amines, carbonates, salts, volatile amines, etc. Highly alkaline sources include sodium hydroxide, potassium hydroxide, etc. , providing a high concentration of hydroxide (OH ") in aqueous solution The neutral, acidic or basic composition of the invention also generally comprises a surfactant agent.The surfactant may include any constituent or constituents, including compounds, polymers and products of reaction that can alter the surface tension in the resulting compositions, helps to remove dirt and suspension by emulsifying dirt and allowing removal through subsequent washing or rinsing.Any number of surfactants can be used including organic surfactants such as anionic surfactants, cationic surfactants, nonionic surfactants, amphoteric agents and mixtures thereof Anionic surfactants such as alkylsulphates and sulphonates, alkyl ether sulphates and sulphonates, alkyl aryl sulphates and sulfone can be used in the concentrate of the invention. coughs, aryl sulfates and sulfonates, and sulfated fatty acid esters, among others. Nonionic surfactants, which have generally been found to be useful in certain optional formulas of the invention, are those comprising portions of ethylene oxide, portions of propylene oxide, as well as mixtures thereof. These nonionic surfactants have been found to have a stable pH in acidic, neutral and alkaline environments, as well as providing the necessary cleaning and the efficiency of soil suspension. A surfactant agent particularly useful in these systems includes the amine oxide surfactants. Useful amine oxide surfactants have the formula: (R2) I (R3) N? O (R i) wherein Rt is a C8-C20 alkyl or a C8-C20 alkylamido-C2-C5 alkyl group , and R2 and R3 are individually lower alkyl of C? -C4 or hydroxy-lower alkyl of C? -C. The composition may also include an improver. The improvers are materials, which improve the detergent effect of the cleaning solutions and can be either organic or non-organic in the composition. Breeders can also exhibit water conditioning properties, and in some cases, act as chelators and sequestrants.

TABLE Vil Concentrated Floor Cleaner with Extra Strength Ammonia FORMU LA: TABLE VIII Concentrated Glass Cleaner without Ammonia FORMULA: The tank for the liquid concentrate is in fluid communication with the concentrate inlet in the vacuum cleaner. The reservoir comprises means for maintaining a sufficient volume of liquid concentrate to allow convenient operation of the apparatus. Typically, the maximum holding capacity of the tank is approximately 750 milliliters to 4 liters. The deposit can be made from a variety of useful materials including thermoplastic materials, reinforced thermoplastic materials, heat setting materials, structural metals, glass, fiberglass, etc. Preferred deposits comprise a matching surface adapted to the shape or configuration of the liquid concentrate container. In addition, the reservoir contains means for opening the container of liquid concentrate having an openable device closure in the container. The matching surface, for the concentrate container, used in the tank, is formed and configured to, (1) support the concentrate container in a position to allow the concentrate to be transferred, drained or passed from the container to the tank or be transferred to the tank, (2) ensure that the appropriate container and concentrate is inserted into the apparatus for dilution, and (3) efficiently open the closure equipment to promote rapid transfer of the concentrate from the container to the tank. The apparatus is typically adapted and configured to dilute a variety of liquid concentrates to useful dilute use concentrations. Cross-contamination of each appliance deposit, within an appropriate concentrate, should be avoided. Acid cleaners can make basic cleaners do not work well. In addition, the addition of a chlorine source to an acid can release inappropriate toxic fumes. A variety of other inappropriate interactions may occur, ultimately resulting in a use solution that is not appropriate for its intended purpose. In order to avoid any cross-contamination of the inappropriate concentrate use solution, each concentrate container is formed and configured to allow insertion of the contain only in an appropriate reservoir containing a surface that matches only the appropriate container. Preferred matching surfaces comprise an indentation on the concentrate container and comprise a form of complementary deposit. The indentation is done on a non-symmetric concentrate container. The concentrate container can be inserted in an individual configuration to an individual tank. The matching reservoir surface is formed to conform itself to the total shape of the container. The interaction between the matching surface in the bottle and the indentation and the form of complementary deposit ensures that only a specific concentrate container can be inserted into the tank. The matching surfaces positioned such that the concentrate container, after insertion into the tank, is in a position such that the contents of the container are easily transferred to the tank. In a preferred embodiment of the invention, the reservoir also contains means for opening a closure, such as a flexible closure band or rigid closure equipment in the concentrate container. If the container is formed and adapted to allow successful insertion of the container into the container, the closure equipment in the concentrate container is brought into contact with opening means. The opening means pierce a closing device in the concentrate container. The closure may comprise a flexible band or a rigid ind. The flexible band may comprise a flexible thermoplastic film, a sheet of metal, or a sheet of paper. A variety of thermoplastics such as the closure can be used, including polyethylene, polypropylene, polyethylene terephthalate or any other known useful film. The metal sheets that can be used include aluminum foil, metallized polyester, etc. The paper webs that may be used include typical cellulosic sheets, cellulosic sheets treated with a hydrophobic material such as silicone, thermoplastic coating materials, film or sheet laminates, etc. The closure equipment preferably comprises a circular or cylindrical insert. The insert fits in a sealed form in the opening of the concentrate container. The equipment typically contains a thermoplastic band seal. The thermoplastic band closure has an opening zone separated from the band through a fracture line defined by a hinge portion and a depressed, weak line. The perforating means easily drill any flexible band closure. The perforating means in the reservoir are brought into contact with and cause the opening zone in the equipment to separate from the band in the fracture line, which is then tilted from the opening over the hinge portion. The web is typically a thermoplastic web having a thickness of about 0.2 to 5 millimeters. The fracture line is typically a line defined in the band as a substantially thinner portion (i.e., approximately 0.1 to 0.5 millimeters) with a hinge portion. The fracture line is preferably formed in the circumference of the band within the equipment and encloses a sufficient opening to allow an effective and rapid transfer of the contents of the deposit. The opening comprises approximately 50% or more of the area of the thermoplastic band. The opening is further defined by a portion of the hinge defined in the fracture line, over which the material removed by the opening of the opening moves to open the thermoplastic band. If the fracture line is substantially less than 0.1 millimeters, the fracture line can be spilled inappropriately. If the fracture line is greater than about 0.5 millimeters or greater than about 50% of the thickness of the thermoplastic band, the opening zone can be difficult to pierce and remove from the equipment during opening. The preferred diameter of the equipment is approximately 10 to 50 millimeters. The thermoplastic band can be configured in a cylindrical insert portion having a height of approximately 10 to 60 thousand meters. The rigid thermoplastic band inside the equipment can be placed inside the equipment at a convenient location. The band can be placed on the outermost edge of the equipment, so close to the inner portion of the equipment bottle, or it can be placed on the extreme outer portion of the equipment when it is inserted into the bottle. The thermoplastic band is typically placed in some intermediate portion, between the ends of the equipment. Such a position is typically used to promote easy opening using the deposit openings. The preferred means for opening the concentrate container are preferably placed in the tank in such a position that the opening means comes into contact with the opening zone and causes the thermoplastic band to fail in the fracture line, allowing the removal of the material in the opening area towards the closure. By removing the material in the opening zone, it is meant that the material can be completely removed in the fracture line and separated from the equipment. Said opening protocol creates a circular portion of the closure band defined by the fracture zone that is completely removed from the equipment leaving an opening, through which the concentrate can pass. Alternatively, the term removal of the material may also connote the displacement of the material from the opening zone, while remaining attached to the equipment on a hinge portion. The opening means cause a failure in the fracture line comprising a circular arc substantially greater than 270 °, preferably greater than 300 ° from the fracture zone, leaving a hinge portion allowing the material to oscillate away from the opening zone , creating a passage for the flow of the concentrate. The diluted use solution is transferred from the suction outlet to the use solution container. The suction outlet can be placed in the opening of the container of the user solution. In said configuration, the solution of use leaves the opening near the neck of the bottle and then comes into contact with the bottom of the container. If foaming of the use solution is a problem, the bottom of the container or the product supply tube can be configured to minimize turbulence and foam generation. Alternatively, the suction outlet can be configured with a tube outlet, which transfers the user solution to the bottom of the use solution container. Said tube transfer configuration substantially reduces the likelihood of foam generation during filling operations. Once opened, the contents of the container can then be sufficient and quickly transferred to the container. The preferred configuration of the means for opening the concentrate container is an elongated member having a sharp edge portion and which extends toward the equipment. The opening means may have a variety of transverse shapes, including circular, triangular, rectangular, etc. In Figure 5 an angled shape of two its surfaces is shown. The preferred opening means contain a portion which ensures that the material removed from the opening zone rotates on a hinge portion and is placed away from the flow of the concentrate towards the reservoir. In certain configurations, the material removed from the opening zone may, under the influence of the concentrate flow, fall into the equipment partially or completely blocking the flow. The opening means configured to ensure that the opening of the container allows the rapid and complete transfer of the concentrate into the tank. The liquid concentrate kept inside the concentrate tank is in liquid communication with the concentrate inlet of the vacuum cleaner. The term "in fluid communication" indicates that the parts of the dilution apparatus are connected so that the liquid flows between the parts (eg, from the reservoir to the aspirator) with little pressure drop and in the absence of substantial leakage. Preferred liquid communication media include a flexible thermoplastic tubing, TYGON® tubing, rigid plastic PVC or CPVC tubing, or other suitable liquid conduit. The diameters of the pipe are important to ensure proper flow, and typically have an internal diameter of not less than 5 millimeters. The liquid media is selected with a minimum length to ensure a minimum pressure drop. The dilution ratio of the liquid concentrate to diluent is typically from about 0.1 to 40 parts of concentrate per 100 parts of diluent, preferably 0.25 30 parts of concentrate per 100 parts of diluent and most preferably about 0.5 to 25 parts of concentrate per 100 parts of diluent. The dilution ratio can be selected through an appropriate selection of suction pipe between the concentrate container and the vacuum cleaner. The control ratio on dilution can also be controlled by inserting a flow restriction device between the concentrate container and the concentrate inlet of the aspirator. Said flow limiterAlso known as a dosing tip or dosing valve, it can be inserted into the tank outlet or vacuum inlet or at any point between the tank and the vacuum cleaner on a transfer line. The diameter of the dosing tip to regulate the flow from the reservoir to the aspirator can be from about 0.25 to 4.75 millimeters and can be easily selected by measuring the dilution ratio as the size of the dosing tip varies from the smallest available diameter to the largest. The liquid diluent is commonly combined with the liquid concentrate in the vacuum cleaner to form the solution of use. The liquid diluent is commonly an aqueous liquid. Useful aqueous liquids include common service water (distributed by local municipal water facilities), soft water, hot water, deionized water, styled water, or other liquid streams commonly available in the institutional or industrial location. The typical liquid diluent is a liquid aqueous diluent comprising service water or hot service water. The plumbing regulation, in the United States, may, in certain circumstances, recommend or require that the flow of service water be interrupted by a vacuum rupture, if variations in water pressure in supply lines can cause withdrawal of the concentrate or diluted use solution to the service lines. When the apparatus of the invention is used in a dilution station containing one or more apparatuses of the invention, the aqueous diluent source can be a common manifold or a common liquid source of the diluent material. The flow of the aqueous diluent through the aspirator causes a reduction in the pressure that expels the concentrate into the diluent stream resulting in the production of the diluted use solution. The flow of the diluent through the aspirator is controlled to ensure that the appropriate volume of diluted use solution is prepared by the action of the aspirator. The flow of the diluent can be controlled in a number of ways. The flow of the diluent can be controlled by a simple hydraulic or electrically operated on / off switch, which is activated by an operator, who visually checks the appropriate fill volume. The switch is activated for a period sufficient to fill the container of solution of use with the solution of use properly diluted. The controller may also comprise a programmed time control device with inputs that result in an appropriate flow of diluent for a sufficient period of time to fill the container. In addition, the controller may have input means that transfer a signal derived from the container indicating the contents of the container to the controller. The input signal can be derived from a wide variety of sensing devices that can perceive the weight, volume, filling or other condition of the container in relation to the required contacts. Once full, the sensor sends signals to the controller to stop the flow. The controller can also be an energized control mechanism. This mechanism, once activated, will remain for a fixed period. Hydraulic timing controllers typically contain passages that, through viscosity and flow, control the time at which the hydraulic controller remains open. The apparatus of the invention typically includes a station for a use solution container positioned to receive the diluted use solution during the operation of the dilution mechanism. Said station is in fluid communication with the suction outlet. In a preferred mode of operation of the dilution apparatus of the invention, the dilution apparatus comprises a container port or container filling station of use solution comprising a defined space in the apparatus. The defined space, preferably depressed, is configured to allow the insertion of a use solution container. The space is configured to support the use solution container and maintain its position during filling. As such, the space comprises a base portion and wall portions that are configured to surround and contain the use solution container. Substantially increased dimensions of the use solution container could prohibit the insertion of the container into the leaching station. Said filling station may have the suction outlet positioned near the upper portion of the use solution container. The suction outlet can contain a flexible filling tube that allows the insertion of the filling tube into the container before the installation of the container in the filling station. When a dilution station is used, having one or more dilution apparatuses, at least one apparatus contains a station for a use solution container. Another dilution apparatus can direct the flow of the diluted use solution to a container other than the container of the use solution. The diluted use solution may be directed through liquid communication means, typically a pipe or other conduit, to a bucket or any arbitrary container. The container for the liquid concentrate and the diluted use solution are substantially similar. By substantially similar, it is meant that the shape of the container allows double use (ie, as a concentrate container and as a container for diluted use solution). The container is configured to fix or coincide with both the concentrate tank and the filling station. The container can be sealed to prevent spillage of the container concentrate during shipping and storage, using closure means. The closure means may comprise a flexible band closure or rigid equipment, adapted to the opening of the container. Preferred flexible webs include thermoplastic films, metal foils and paper webs. A preferred equipment comprises a cylindrical equipment having a rigid thermoplastic band having an opening zone defined by an easily fractured fracture zone, which defines a circular opening. A hinged fracture piece is removed from the opening area. The equipment (see Figures 3, 4 and 8) is inserted into the bottleneck and couples, in sealed form, the inside of the bottleneck with the outside of the cylindrical equipment, in a preferred mode, the equipment can be ventilated. The equipment may have a vent opening in the thermoplastic band of the equipment preferably in the fracture zone. The vent can then be covered with sealing means that allow escape of gas or vapor from inside the container without allowing the liquid to leave the container. Typical mechanical valve means can be used. Alternatively, a hydrophobic membrane can be used to seal the ventilation. The container, sealed by the flexible band or equipment, may have a lid that is installed to further seal the container. Conventional lids can be used that provide an additional seal, avoiding the escape of any liquid or gas. Alternatively, a ventilated lid can be used. The ventilated covers comprise a construction of covers that have ventilation means. Useful ventilation means include an opening in the lid or a permeable liner, installed inside the lid. The opening of the lid can be covered with a hydrophobic film which acts to allow the vapor or gas from the container to escape from the lid, while retaining any liquid. A preferred alternative is a porous liner that allows the escape of gas or vapor. A variety of such linings are available in the market. Said liners comprise porous expanded thermoplastic materials, thermoplastic materials having wafer impressions on the surface of the thermoplastic, ventilation openings and other known means of ventilation. These covers are commonly used with the alternative of ventilated equipment. The preferred concentrate container can be inserted into the tank. The surface of the container coincides with the only shape or configuration of the internal surface of the tank, and when it is inserted it can be opened by the opening means in the tank causing the drainage or transfer of the contents of the container to the tank. Once empty, the container can then be placed in the filling station for the use solution container, and can be filled with the diluted use solution immediately after filling the tank or at any arbitrary time, afterwards. The shape and configuration of the use solution container and the concentrate container are similar, preferably identical. After the concentrate solution has been transferred to the tank, the container can be used with the equipment remaining in place. Optionally, the opening equipment can be removed from the neck of the container. A sprayer head or other spraying adapter mechanism can be inserted into the use solution container and can keep the equipment in an open position allowing the dilute use solution flow from the container. The container can have a liquid capacity of about 750 to 2000 milliliters, preferably 850 to 1000 milliliters. The container can also be adapted to the insertion of a spray head operated by manual compression of the trigger to supply the use solution to the cleaning site. This common container system, both for the liquid concentrate and for the use solution, can allow the recirculation of accumulated containers for the washing, filling and redistribution of containers. Preferably, the containers are made of common thermoplastics including polyethylene, polypropylene, polyester, PVC, PET, etc.

The bottle filling system is operated by inserting the concentrate container 1 1 A into the tank 10 by transferring the contents of the concentrate 2 from the container 1 1 A to the storage container 12 through the action of the opening means. When the diluted use solution 5 is commanded by the controller 14, the solenoid valve 15 is driven allowing the diluent under pressure to pass through the aspirator 16 by ejecting the concentrate 2 in the aspirator 16 to mix with the aqueous diluent. The mixed concentrate 2 and the aqueous diluent form a diluted use solution within the 1 1 B diluent use solution container. When the concentrate container 1 1 A is empty, the container 1 1 A can be removed from the tank 10 and can be installed in the filling station 7, as a container of use solution 1 1 B in the vacuum cleaner 16 is Figure 2 is a plan view of a device 20 that can be inserted in a container for the liquid concentrate that allows easy opening of the equipment by means of bottle opening in the reservoir. concentrated. The equipment comprises a substantially cylindrical body 21 surrounding a circular band enclosure 22 enclosing the interior of the cylindrical member 21. The circular enclosure 22 contains a fracture line 23 in the closing band 22. The band 22 comprises an opening zone 25., a fracture line 23 and a band flange zone 27. The fracture line 23 is a depressed portion of the band adapted to fail when in contact with the opening means in the reservoir. The fracture line 23 comprises a substantially circular line. A portion of the circumference of the fracture line comprises a hinge portion 24. The hinge portion 24 is also a depressed area in the band 22. However, the hinge depression area is wider than the fracture line 23. When opened, the hinge area 24 keeps the enclosure 22 attached to the equipment to prevent plugging. The equipment also contains a flange 26 which engages, in sealed form, the concentrate container opening. Figure 3 shows a cross-section of the equipment of Figure 2 inserted in the neck of a concentrate container 30.

The equipment comprises a sealing band 47 comprising the fracture line 48, the opening area 47a, the band flange 47b, and a ventilation opening 45 sealed with a hydrophobic film 49. The sealing band 47, when opened fracturing the fracture zone 48 leaves a band flange 47b and an opening portion 47a, which is completely removed or on a hinge member of the opening. The sealing band 47 also comprises an opening 45 dimensioned to allow the escape of gases or vapors from the container. The opening 45 is sealed through the membrane 49. The membrane 49 is a hydrophobic membrane that can pass gas or vapor, but substantially retains the liquid. Figure 5 shows a cross-section of the matching surface and the portion of opening means of the reservoir (see Figure 1). Figure 5 generally shows the matching surface 50 shaped to adapt the shape or configuration of the concentrate container (see Figure 6). The matching surface has portions 57 adapted to the handle portion 51 to the neck portion of the bottle and 52 a body portion adapted to the body portion of the bottle. The matching surface 50 of the reservoir also comprises a drainage portion 53, through which the contents of the concentrate container are transferred to a reservoir container. Operably connected with the drainage portion 53 are the opening means 54 comprising a perforating end 55 and a tab 56. As the concentrate container is inserted into the matching surface 50, the equipment is brought into contact with the perforating means 55, which opens the equipment causing the concentrate to drain from the bottle through the drain portion 53 into the concentrate tank container (not shown). The tab portion 56 maintains the equipment opening area (not shown) positioned at an angle, so that the flow of the concentrate is not substantially reduced or interrupted during the transfer of the concentrate into the storage container.

Figure 7 is identical to Figure 1, except with respect to the control means operating the apparatus of the invention. In this embodiment, water flows from a common manifold 17 through a supply line 3 to a valve 15 controlled by a hydraulic on / off switch 74. Compression of switch 74 activates a flow of diluent through the vacuum cleaner 16 , ejecting concentrate 2 for the appropriate dilution. The dilution results in a use solution 5 which fills the use solution container 11 B. After the filling operations are completed, the switch 74 can be removed from its actuation position. Alternatively, switch 74 can be spring loaded. Once the pressure of the switch 74 is removed, the spring charging mechanism (not shown) returns to the switch to its position, preventing the flow of diluent. Figure 8 shows a cross-sectional view of a closure device 80 inserted in the neck 84 of a container 60 (see Figure 6). The container is closed with a lid 90. This configuration comprises a ventilated equipment and a ventilated lid.
