Patent Application
20080011779
The present invention is directed to dispensers, in particular dispenser for storing and selectively dispensing one or more products.
The use of spray bottles for dispensing chemical reagents (e.g., water, cleaners, soaps, insecticides, hair spray, etc.) are well known. Due to regulations limiting the amount of volatile organic carbons (VOC.) released in the atmosphere, products originally contained and dispensed through aerosols are currently being replaced with spray bottles.
Bottlers of chemical reagents typically market their products by purchasing separately empty plastic container bottles and spray heads. The bottlers then fill, assemble, and label the completed spray bottle packages for delivery to retailers. Consumers purchase the filled spray bottles at the point-of-sale, and then use the chemical contents of the spray bottle. Most consumers dispose of the spray bottle upon the one time use of the contents of the spray bottles. However, the spray bottles are still fully functional with respect to containing and dispensing chemical reagents, since the plastic bottles are substantially chemically resistant and the spray heads remain fully functional after using the contents. Conventional point-of-sale type spray bottles can be recharged numerous times with chemical concentrate and water (i.e., at least 10 times, possibly 100 times while maintaining full operation). Thus, consumers dispose of large quantities of reusable product (i.e, empty spray bottles) having high utility value.
In today's environment of numerous regulations to control pollution, and consumer and industrial awareness for conserving resources and reducing landfill waste, it is highly desirable to promote the reuse of products that maintain their utility, and dispose of only products that no longer have any utility. Many bottlers are currently selling concentrate in various sized containers to allow consumers to recharge point-of-sale type spray bottles with their particular concentrates. However, many consumers are unwilling to adopt such methods apparently due to some inconvenience in the steps involved with the recharging process of the spray bottles. In particular, there is some inconvenience in removing the spray head, opening the chemical concentrate container, pouring the chemical concentrate into the empty spray bottle, adding water, and reattaching the spray head to the bottle. Further, consumers apparently lack interest in recharging spray bottles due to some reluctance based on their inexperience and knowledge in mixing and diluting liquids, which is done by processing chemists for the bottlers. In addition, recharging is usually a messy undertaking due to spillage of chemical concentrate while pouring from one container to the other, overfilling, accidentally knocking over the bottle being filled due to its instability when unfilled, and other undesirable mishaps that can occur, that provide substantial inconveniences.
Importantly, sizeable containers (e.g., pint, quart, gallon, liter sizes) of chemical concentrate can be significantly hazardous to transport and handle by consumers unaware of the potent chemical properties of the chemical concentrates. Specifically, chemical spills of concentrate can damage items around the home including flooring, carpeting, counter top in kitchens and bathrooms, shelves, and other items the chemical concentrate could potentially come into contact with. Further, chemical concentrate can impose a significantly greater health risk to persons coming into accidental contact therewith potentially causing tissue burns and other damages.
Most importantly, chemical concentrate imposes a great risk to children who may accidentally ingest the chemical concentrate and become poisoned. Chemical concentrate greatly increases the chance of permanent injury or death in this regard to children versus current diluted chemical reagents contained in point-of-sale type spray bottles.
The dispensers, container, lids and seals according to the present invention, in particular the cartridges or inserts, can serve as packaging for many types of products. These dispensers provide the advantage of storing and dispensing multiple similar products or multiple different products. There advantages will be described herein below.
A first object of the present invention is to provide a rechargeable dispenser, in particular a spray bottle dispenser having one or more chemical concentrate reservoirs associated with the spray bottle dispenser.
A second object of the present invention is to provide a rechargeable dispenser, in particular a spray bottle dispenser having one or more chemical concentrate reservoirs disposed with the spray bottle dispenser.
A third object of the present invention is to provide a rechargeable dispenser, in particular a spray bottle having one or more chemical concentrate reservoirs disposed within the spray bottle dispenser, and accessible by bursting.
A fourth object of the present invention is to provide a rechargeable dispenser, in particular a spray bottle having one or more chemical concentrate reservoirs disposed within the spray bottle dispenser, and accessible by puncturing.
These and other objects can be achieved by the rechargeable dispenser, in particular the spray bottle dispenser according to the present invention.
The main concept according to the present invention is to provide a rechargeable dispenser, in particular a spray bottle dispenser package having at least one supply of chemical to allow the spray bottle dispenser to be recharged at least one time. The chemical can be in the form of a gas, liquid, semi-solid or solid. Specifically, the chemical liquid can be a one phase mixture, a two phase mixture, a dispersion or any other chemical reagent having liquid characteristics. The chemical semi-solid can be in the form of a slurry, paste, solid dispersed in a liquid that still exhibits some liquid type characteristics, and the solid can be in the form of a powder, granules, tablet or other solid material form.
The chemical is preferably a concentrated chemical that is readily diluted with a solvent, in particular plain water. Preferably, the chemical can be immediately diluted, however, a chemical substance that can go into solution over a 24 hour or longer period of time can potentially be suitable for some applications.
The preferred embodiments of the present invention involve associating at least one quantity of chemical with the spray bottle dispenser itself. Specifically, the chemical is stored in some manner, and connected directly internally or externally to the spray bottle dispenser. However, the present invention is broader in scope to include packaging the chemical and spray bottle dispenser together (i.e., connected indirectly) to be marketed at the point-of-sale. In this embodiment of the invention, a consumer would purchase the package containing a supply of chemical and the spray bottle dispenser, separate at home the spray bottle dispenser that has been filled by the bottler from the package and store the chemical portion of the package separate from the spray bottle dispenser in the household. The user would then retrieve the stored chemical upon consuming the initial contents of the spray bottle dispenser for purposes of recharging tle spray bottle dispenser.
The preferred embodiments of the invention store the at least one quantity of chemical directly or indirectly inside or outside the spray bottle dispenser. In the case of an indirect connection to the spray bottle dispenser, a mechanical fastener such as a plastic strip connects an external chemical reservoir to the spray bottle dispenser. In the case of a direct connection, the chemical reservoir is directly connected internally or externally to the spray bottle dispenser. The most preferred embodiments store the at least one quantity of chemical inside the spray bottle dispenser, particularly the bottle portion, to fully contain any inadvertent spills or leakage of chemical through the life of the spray bottle dispenser. These most preferred embodiments provide substantial advantages for handling, recharging and protecting household items from contact with chemical, and most importantly to prevent accidental ingestion by children. This particular point is especially important due to the much greater potency of chemical concentrate versus diluted chemical reagents currently being sold by bottlers at point-of-sale.
The most preferred embodiments also utilize conventional spray bottle dispenser components including plastic bottles, plastic spray heads, and plastic downtubes. In order to promote products incorporating the present invention, it is particularly important to utilize the standard components that are readily available and relatively inexpensive due to the large quantities sold and consumed. Thus, an add-on chemical reservoir for storing the chemical is highly desirable.
The most preferred add-on type chemical reservoir is an insert received within the bottle portion of the spray bottle dispenser. This type of insert can be manufactured extremely cheaply in high volume while providing all the performance characteristics necessary for a safe and reliable product. Specifically, the insert can be made with one or more chambers or cells containing chemical that can be accessed in various ways. For example, the reservoir can be sealed with membranes that can be punctured with an instrument, in particular the tip of the downtube. Alternatively, the walls of the chemical reservoir can be designed or configured so as to be readily bursted upon application of external pressure to the chemical reservoir. Adding lines of weaknesses, thinning of walls and other means for locally weakening a portion of the chemical reservoir can be implemented for use in the present invention.
Alternatively, one or more of the components of the conventional spray bottle dispenser (e.g., bottle portion, spray head portion, downtube) can be modified to provide the chemical reservoir. For example, the walls or bottom of the bottle portion can be modified, by molding a chemical reservoir in one or more sides or bottom of the bottle portion, the spray head portion can be provided with a chemical reservoir, and/or the downtube can be provided with an add-on chemical reservoir or the walls of the downtube can be molded to provide a chemical reservoir. However, all of these approaches will initially be substantially greater in cost due to the modification of conventional components not necessitated by the use of an insert according to the present invention.
The insert according to the present invention can take on many different forms and configurations. A first preferred embodiment of the insert is defined by a cylinder having one or more chambers or cells disposed therein. The interior of the cylinder can be provided with one or more bisecting walls to define the chambers along the length thereof. A plastic cylinder having one or more bisecting walls can be easily extruded in plastic. The top and bottom of the one or more chambers of the insert are sealed by upper and lower sealing membranes. The membranes can be films, foils, composites of films and foils, or any other suitable composite that is both chemically resistant and subject to being punctured readily by an instrument, in particular, the tip of the downtube, or can be made to burst.
The upper and lower sealing membranes can be connected to the insert by bonding, adhesive bonding, thermal bonding, sonic welding, or suitable methods for forming a liquid tight seal (e.g., hermetic seal).
This embodiment of the insert can be marketed inside a filled spray bottle dispenser at point-of-sale. The downtube extends through an open chamber of this insert down into the lower portion of the bottle portion to access premixed chemical reagent added by the bottler during manufacture. After consumption of the chemical reagent, a user unscrews the spray head and lifts the downtube from the bottle portion. The insert is rotated so that one chemical reservoir is now positioned where the open chamber was previously positioned (i.e., now registered for being punctured by the downtube). The user then forces the tip of the downtube through the upper sealing membrane, down through the chamber, and then punctures the lower sealing membrane. Water can be added through the open chamber of the insert before or after the step of accessing the chemical reservoir by puncturing with the downtube. This configuration allows the chemical to be always stored within the confines of the spray bottle dispenser, and minimizes the steps needed for recharging the spray bottle dispenser.
The consumer will experience little inconvenience in removing the spray head and downtube from the bottle portion, rotating the insert, puncturing the chemical reservoir, adding water through the open chamber of the insert, and reassembling the spray head portion to the bottle portion. Further, the chemical concentrate stored within the insert is extremely safe for handling and preventing accidental consumption by children (i.e., a child would have to successfully unscrew the spray head portion from the bottle portion, fully remove the downtube from the bottle portion, and successfully puncture the insert). Further, even in the event of puncture of the insert by a child, the access opening through the upper sealing membrane would be sufficiently small to substantially limit spilling and containing most chemical from being easily ingested by a child. Thus, the present invention provides substantial safeguards over current methods of selling large quantities of chemical concentrate at the point-of-sale, and subsequently having the consumer handle and mix the chemical concentrate in his or her home.
This particular insert can have one, two, three, four or more separate chambers or cells. For example, in the case of four cells, one cell would be an open cell through which the downtube is initially placed by the bottler during assembly when the spray bottle dispenser is provided with an initial charge of diluted chemical. Thus, in this example, there remains three cells that can be utilized as three separate chemical reservoirs. This four cell configuration would allow the user to initially consume the premixed diluted chemical reagents of the spray bottle dispenser, and then recharge the spray bottle dispenser three more times prior to consuming all the chemical contained in the spray bottle dispenser. If the consumer then disposed of the spray bottle dispenser at that point, this would provide a three time improvement over the current practice of consumers utilizing a spray bottle dispenser one time prior to disposal. Thus, the consumption of spray bottle dispensers could be reduced three-fold (i.e., one fourth the waste) if fully implements.
However, this invention can even provide for an even greater improvement over the current practices by consumers. Specifically, this insert can also be sold at the point-of-sale as a separate item that could be added to a conventional point-of-sale type spray bottle dispensers having no inserts after the initial consumption of the contents, or for use with spray bottle dispensers having inserts according to the present invention after the complete chemical consumption of the inserts initially sold with the units.
This new system would greatly decrease the shipping weight and costs associated therewith, decrease retail shelf space for marketing the product, and most importantly greatly decrease the consumption and waste of plastic material. Specifically, the volume of plastic needed to make the four chamber insert described above would be a small fraction compared with the weight of four conventional spray bottle dispensers based on equal amounts of useable diluted chemical reagent.
Further, conventional spray bottle dispensers are substantially much greater in cost to produce relative to the insert according to the present invention, and would conserve significant labor and other direct and indirect costs associated with the production of conventional spray bottle dispenser components versus the insert according to the present invention. Further, the insert according to the present invention can readily be recycled, and could potentially be refilled if an adequate system were developed to reprocess such inserts, however, more than likely the inserts would be disposed of by consumers based on convenience factors.
A second embodiment of an insert according to the present invention involves forming a strip of chemical reservoirs that can be disposed within the bottle portion of the spray bottle dispenser. The strip of chemical reservoirs can be made at high speed, and would most likely be made in a continuous strip and cut to length when completed for insulation in each spray bottle dispenser. The strip type insert can be manufactured by a high speed molding technique such as vacuum forming the chemical reservoirs from a plastic strip, filling the chemical reservoirs with chemical, and sealing the chemical reservoirs. This completed strip is then cut to length based on the number of reservoirs to be added to the spray bottle dispenser, and is preferably attached by adhesive or other technique to the inside surface of the bottle portion. The chemical reservoirs made of the plastic strip are made in such a manner that the chemical reservoirs can be punctured by an instrument, in particular, the tip of the downtube, or can be made to burst by adding external pressure to the chemical reservoir. A user can burst one or more (i.e. one, two, three, etc.) of the chemical reservoirs to specifically tailor the concentration of the diluted chemical reagent. Thus, the present invention allows the consumer some latitude in selecting concentration levels currently unavailable with conventional spray bottle dispensers.
In a third embodiment, a plurality of separate cylindrical chemical reservoirs can be added to the inside of the bottom portion. The cylinder chemical reservoirs are provided with upper sealing membrane that can be punctured by an instrument, in particular the tip of the downtube. The cylinder reservoirs can be separate units or connected together by a strip, or by some other manner. The cylindrical chemical reservoirs are preferably located at the bottom wall of the bottom portion to allow easy access by the tip of the downtube during a puncturing operation.
In a fourth embodiment, cylindrical chemical reservoirs bridge the side walls of the bottle portion. The cylinder reservoirs are made so they can be burst by simply pressing together the walls at the location of the particular cylinder reservoir.
In a fifth embodiment, separate donut-shaped chemical reservoirs are added to a conventional downtube. The donut-shaped reservoirs can be made so as to be punctured or burst for chemical access. Alternatively, one or more small holes through the inner surface of the donut-shaped reservoirs can be provided and sealed by the downtube itself (adhesive can also be provided to insure adequate sealing). In this type of arrangement, the chemical inside the donut-shaped reservoir can be accessed by simply pulling the donut-shaped chemical reservoir off the downtube exposing the opening through the inner wall of the donut-shaped reservoir. The donut-shaped reservoir can be removed by unscrewing the spray head portion from the bottle portion, lifting the downtube until the lowermost donut-shaped reservoir is located at or near the opening of the bottle portion, holding the donut-shaped reservoir by the fingertips of one hand at the opening to the bottle portion, and then lifting with the other hand the downtube so as to detach the donut-shaped reservoir from the downtube, and then allowing the donut-shaped reservoir to drop into the bottle. Water is added before or after to dilute the concentrate to form the diluted chemical reagent.
In a sixth embodiment, an insert is provided with a plurality of reservoirs in a stepped and stacked array. The top reservoir is thinner and deeper compared with a bottom reservoir that is wider and shallower. One or more reservoirs having dimensions in between that of the top and bottom reservoirs can be provided therebetween. This stepped and stacked arrangement allows easy access to any of the chemical reservoirs by an instrument, in particular the tip of the downtube for puncturing a membrane sealing each reservoir.
In a seventh embodiment, a plurality of reservoirs are provided in an insert and a stacked arrangement. Each reservoir is sealed at the top and bottom with a sealing membrane. A person using a spray bottle dispenser containing this insert initially punctures the upper and lower sealing membrane of the upper reservoir during a first recharging operation, punctures the upper and lower sealing membranes of the middle reservoir to access chemical in the middle reservoir during a second recharging operation, and does the same to the third chemical reservoir in the third recharging operation.

The containers and dispensers according to the present invention can be unitized with substances or products in various physical states including gas, liquid, solid (e.g. pills, packets), paste, slurries, unsaturated solutions, super saturated solutions, multi-phase substances, combinations of these physical states mixed, blended, reacted, dispersed, or associated in some manner), and other types of suitable physical states.
The containers and dispensers according to the present invention are particularly suitable for containing, storing, mixing, blending, reacting, dispersing, or otherwise associating one or more substances or products. The dispenser according to the present invention is particularly suitable for containing, storing, mixing, blending, reacting, and/or dispersing at least one concentrated substance or product with at least one diluent (e.g. water, solvent, premixed reagent, diluted reagent, etc.). In this manner, one or more charges of concentrate substance(s) or product(s) can be diluted and dispensed from the dispenser according to the present invention. In some preferred embodiments, multiple charges of concentrated substance or product can be associated with the dispenser, preferably stored within the dispenser, and then simultaneously or selectively utilized to charge or recharge the dispenser.
An object of the present invention is to provide an improved container.
A second object of the present invention is to provide an improved container having multiple compartments and/or reservoirs in combination with a seal connected to the container for sealing the compartments and at least one closure connected to the container.
The present invention is directed to a container configured for containing product. The container includes multiple compartments that can be configured to be simultaneously accessed or selectively accessed. A seal is connected to the container for sealing the compartments, and a closure is connected to the container. Preferably, the closure covers and protects the seal.
The seal can be defined by a single piece configured to be selectively separated into separate seal portions. For example, a single seal can be provided with lines of perforation and/or lines of weakness to allow tearing between adjacent sealed portions. The sealed portions can be provided with separate pull tabs to allow the seal to be separated into separate sealed portions. Alternatively, the seal can be defined by separate sealed portions that are applied to the container as separate portions and/or separated from each other due to a cutting operation (e.g. for example by use of a dye).
In a preferred embodiment, a removable cap (e.g. screw off or snap cap) is used to cover and protect the seal connected to the container for sealing the separate compartments of the container. The separate seal portions, as an option, can be each provided with a separate pull tab. The separate sections of the seal, for example, can be selectively removed by a user gripping the pull tab and removing that particular section.
The seal can be a washer, membrane, wall portion, separate container, bag, wrap, foil, matrix, composite material, or any device configured to provide additional packaging to prevent leakage, provide an air tight environment to promote freshness and shelf life and stability of the substance(s) or product(s).
The dispenser or container according to the present invention, can be a stand alone dispenser or container, or preferably is utilized as an insert within another container, in particular for use as a rechargeable dispenser. A user can selectively access substance or product contained within one of the compartments of the container to be added to another container, and for example, be mixed with a diluent such as water. In some embodiments, the insert can remain within another container while accessing the separate compartments, and in other embodiments the insert is removed from another container, one of the seals is selectively accessed and the contents poured into another container, and then the container is reinstalled into another container. In this manner, a user can selectively access product stored for later use in another container.
The dispensers according to the present invention can be utilized as stand alone type containers or packages for storing and dispensing a wide variety of products. In preferred embodiments, the dispensers according to the present invention utilize multiple chambers or reservoirs, which preferably are selectively accessible so that product from one chamber can be removed while products in other chambers can continue to be stored as the one product is dispensed. Alternatively, two or more products can be dispensed simultaneously in some embodiments with or without selective access to additional products.
The products to be stored and dispensed with the dispensers according to the present invention include chemicals, pharmaceuticals, beverages, food, candy, utilitarian objects such as matches, toothpicks, pins, needles, hairpins, paperclips, and potentially thousands of other products. The products can be liquid, fluid, gas, solid, powder, slurry, paste, gel, or a wide variety of other types of products. Preferably, the products are flowable such as liquids, powders and/or particulates to facilitate dispensing of these types of products.
Preferably, the dispensers according to the present invention include a multiple-chamber component made as a single piece or integral unit. For example, this component is made as a single piece plastic injection molded article to reduce assembly and the cost of making such an article in high volume. More preferred embodiments of the dispensers according to the present invention include a multiple chamber component or container having a depth greater than a width thereof. In some of these more preferred embodiments, the height is significantly greater than the width of this particular component. In a most preferred embodiment thereof, the component has multiple chambers accessible from the top of the container, and is split into multiple chambers by one or more partitioning or dividing wall portions of the container. A particularly preferred embodiment utilizes a substantially cylinder or cup-shaped outer wall portion having one or more dividing wall portions to provide equally sized and shaped multiple compartments accessible from the top of the container. Preferably, this type of container includes an upper lip portion for a variety of various applications and combinations with closures. This particular embodiment allows for the use of a substantially cylindrical shaped closure (e.g. snap cap, threaded cap, lid, etc.), which allows for a tight and evenly distributed seal around the perimeter thereof with the cylindrical or cup-shaped container.
In some embodiments of the containers according to the present invention, the top wall portions and/or bottom wall portions can provide access to the multiple compartments or chambers within the container. In some applications, these wall portions are defined by sealing membranes (e.g. heat sealed and/or inductive sealed to the plastic injection molded container), or are openable, breakable or frangible wall portions of the plastic injection molded container itself. In some preferred embodiments, the membranes are provided with an additional protective seal or cap so as to prevent damage or inadvertent opening of the container during shipping, handling and/or storing. Thus, in some preferred embodiments, the product is doubly, triply or even more packaged to prevent leakage, decomposition of the products, oxidation, protection of the product to provide long shelf life and stability of the product contained therein.
In some of the most preferred embodiments, the multiple chamber or compartment container is configured as a cartridge or insert for use in a dispensing container or package. In this manner, the cartridge containing product, after its contents have been consumed, can be replaced with another cartridge or insert within the same dispensing container or package to allow recharging or reuse of the original dispenser. In this manner, it is desirable that the cartridge is somewhat disposable and the remaining portions of the dispenser are more permanent for reuse to significantly reduce the waste of plastic material and the cost of using the same or similar products repeatedly. In some specialized packaging or containers or dispensers according to the present invention, the cartridge or insert in the dispenser are mixed together with other products contained within the cartridge or insert, and/or added to the dispenser itself. For example, the cartridge or insert can contain a concentrated beverage liquid or powder that can be mixed with water within the dispenser for making a diluted ready-to-use product.
The multiple chamber dispenser according to the present invention has many advantages of providing the same product, slightly different product and/or different products within the chambers or compartments thereof. For example, the compartments can all contain the same color and same flavored product. Another example utilizes the same product (e.g. liquid or powder beverage concentrate) having different colors and different flavors in the various compartments or chambers of the dispenser. As a further example, a beverage concentrated liquid or powder having a particular flavor can be stored in one chamber, a candy such as M&M Minis can be stored in another chamber, pretzel sticks can be stored in a further chamber and nuts and/or raisins can be stored in an additional chamber within the same dispenser.
In another embodiment, M&M Minis are packaged in the dispenser so that one color is in one compartment and another color is in another compartment and so forth. Another example utilizes Runts having yellow bananas in one storage compartment, orange colored oranges stored in another compartment, green colored limes stored in a further compartment and so forth. As a further example, one colored Nerds is stored in one compartment, another colored Nerds is stored in an another compartment and so forth. As an even further embodiment, one color and flavored Pop Rocks is stored in one compartment, another color and flavored Pop Rocks is stored in another compartment and so forth. In other embodiments, M&Ms are stored in one compartment, Runts are stored in another compartment and Nerds are stored in a further compartment and so forth. Thus, the dispensers according to the present invention allow for the selective dispensing of different flavors, different colors, different candy products, and possibly a candy product in combination with one or more toys to be dispensed from the container thereof. The multiple chamber component can be made of clear plastic or natural (e.g. natural polyethylene or natural polypropylene) and configured to allow a user to see the various colored and/or types of products stored therein.
In regards to beverage products, the multiple chamber container or dispenser according to the present invention can be utilized to store and dispense ready-to-use products and/or concentrated products. For example, the multiple chamber container can utilize the same color and same flavor product and/or can contain various colored and flavored products (e.g. variety pack). The container can also contain beverage product in one compartment and food product (e.g. pretzel sticks) in another compartment, a candy product (e.g. M&M Minis) in a further compartment and so forth. Thus, the dispenser according to the present invention can selectively store and dispense numerous same products, similar products and/or different products.
The spray bottle dispenser according to the present invention includes one or more reservoirs containing chemical or chemicals (i.e., chemical reservoirs).
The chemical reservoir can be a separate unit indirectly associated with the spray bottle dispenser by packaging, or directly associated to the spray bottle dispenser by connection to the spray bottle dispenser externally or internally. Preferred embodiments contain the one or more chemical reservoirs internally, most preferably contained inside the bottle portion to fully contain an inadvertent chemical spill or release from the one or more chemical reservoirs.
In the case of an external connection with the spray bottle dispenser, the chemical reservoir can be connected by a separate piece mechanical fastener such as a plastic tab or strip connector connecting the chemical reservoir to the bottle portion, spray head portion, or connected to both the bottle portions and spray head portions of the spray bottle dispenser.
Alternatively, the chemical reservoir can be formed as an integral portion of the bottle portion, spray head portion, and/or downtube. In the integral embodiments, the chemical reservoir can be connected by adhesive, plastic welding, plastic forming (e.g., molding), or by other means to directly integrate the reservoir into the spray bottle dispenser components.
In a preferred embodiment, the spray bottle dispenser is provided with one or more separate chemical reservoirs to allow the spray bottle dispenser to be recharged one or more time. In a most preferred embodiments, the spray bottle dispenser is provided with one or more chemical reservoirs to allow the user to access more than one chemical reservoirs during a single recharge to increase (e.g., double, triple, quadruple, etc.) the chemical concentration of the recharging mixture in the particular recharging operation.
The chemical reservoirs can be identical units to simplify and reduce costs of manufacturing, or alternatively, can be different size, shape and/or configuration of chemical reservoirs. For example, both internally and externally connected chemical reservoirs can be applied, and/or integral and separate type chemical reservoirs can be combined.
The one or more chemical reservoirs of the spray bottle dispenser contain chemical or chemicals. Specifically, the reservoir can be filled or partially filled with only a single chemical compound, a one phase mixture of chemicals, a two phase mixture of chemicals, a dispersion, or any other liquid type chemical(s). Alternatively, the chemical(s) can be in the form of a solid such as a tablet, powder, or granules, or semi-solid such as a thick slurry. In any event, the reservoir should contain a chemical reagent that is readily diluted or dissolvable with a solvent, particularly plain water.
A preferred embodiment of a spray bottle dispenser 10 according to the present invention is shown in
The spray bottle dispenser 10 is fitted with an insert 20 having three separate chambers 22, 24 and 26. In the embodiment of the insert 20 as shown in
The chambers 22, 24 and 26 are used for storing a predetermined quantity of liquid concentrate in each chamber. The chambers 24 and 26 are sealed at the top by an upper sealing membrane 32 and the bottom of the chambers 24 and 26 are sealed by lower sealing membrane 34 as shown in
The insert 20 is preferably made of suitable plastic material, and the upper sealing membrane 32 and lower sealing membrane 34 are preferably made of suitable plastic film, metal foil, or other suitable single or composite layer. The membranes should be chemically resistant to the contents and suitable for making a liquid tight seal with the insert. The upper sealing membrane 32 and lower sealing membrane 34 can be attached to the insert 20 by various means. For example, the membranes 32 and 34 can be attached by bonding, adhesive bonding, thermal welding, sonic welding, or by any suitable conventional means for providing a liquid tight seal (e.g., hermetic seal) of the chambers 22, 24 and 26.
Various other inserts having suitable configurations can be substituted for the insert 20 shown in
The insert 20 can be made by a variety of different techniques, however, injection molding or extruding techniques are the most suitable methods of manufacture.
The insert 20 can be marketed inside the bottle at the point-of-sale, and/or can be marketed as a separate unit that can be inserted into a conventional spray bottle.
In the case of the insert being marketed inside the bottle, all three (3) chambers 22, 24 and 26 can initially be chemical reservoirs. The bottle is filled with water or other suitable diluting liquid and the top sealing membrane 32 and bottom sealing membrane 34 sealing the chamber 22 can be punctured by the tip of the downtube 18 during insertion of the downtube into the bottle portion prior to securely fastening the spray head to the bottle portion to complete the packaging assembly.
Alternatively, the chamber 22 may be open (i.e., devoid of any liquid concentrate, as discussed above) and the bottle is initially filled with proper concentration diluted chemical reagent liquid ready to be marketed with the downtube 18 passed through the open chamber 22 during assembly. In the embodiment having three (3) chambers as shown in
A second embodiment of a spray bottle 100 according to the present invention as shown in
In this second embodiment, a strip 110 having a plurality of chemical reservoirs 112 containing liquid concentrate is provided in the bottle portion 104. The strip 110 is attached to an inside surface of one wall of the bottle portion 104. The specific location of the strip 110 can be changed from that shown in
The strip 110 is preferably made in an infinite length, and then cut to length for the particular application. Thus, different size bottles could potentially have more or less number of individual chemical reservoirs 112. Further, making the strip 112 in an infinite manner would allow for high speed production of the strip 110 for high speed insertion during bottling. In the embodiment shown in
In this third embodiment, a plurality of chemical reservoirs 210 are provided at the bottom of the bottle portion 204. The chemical reservoirs 210 can be individual chemical reservoirs, or alternatively, can be connected together by mechanical coupler in some manner. In any event, the chemical reservoirs 210 must be configured in such a manner so that they can be passed through the open mouth of the bottle portion 204.
A detailed cross-sectional view of one of the chemical reservoirs 210 is shown in
In use, the spray bottle dispenser 200 is filled by the bottler with diluted chemical reagent. The four (4) chemical reservoirs 210 are each at least partially filled with a chemical concentrate. Thus, this particular configuration allows for four (4) recharging operations. Each recharging operation begins with unscrewing the threaded coupler of the spray head portion 202 from the spray bottle 204, and slightly lifting the spray head portion 202 upwardly until the tip of the downtube 208 clears the upper surfaces of the reservoirs 210. The user then forces the tip of the downtube 208 through the metal foil 214 of one of the reservoirs 210 causing it to be punctured. The bottle portion 204 is filled with water either before or after the step of accessing one of the chemical reservoirs 210.
A fourth embodiment of a spray bottle dispenser 300 according to the present invention is shown in FIGS. 12 to 14. The spray bottle dispenser 300 comprises a spray head portion 302 and a bottle portion 304. The spray head portion 302 includes a threaded coupler 306 for connecting the spray head portion 302 to a threaded neck of the bottle portion 304. A downtube 308 is connected to the spray head portion 302, and extends down to the bottom portion of the bottle portion 304.
In this fourth embodiment, strips 310 and 312 connect together a plurality of chemical reservoirs 314. Five (5) reservoirs are shown in
The reservoir 314 is provided with lines of weakness 316 as shown in
The strips 310 and 312 are preferably secured to the walls of the bottle portion 304. For example, the strips 310 and 312 can be adhered with adhesive, or connected by sonic welding or thermal welding. The strip 310 and chemical reservoirs can be molded from plastic.
In this particular embodiment, the spray bottle dispenser 300 is recharged by bursting one or more of the reservoirs 314. The more reservoirs 314 that are burst, the stronger in concentration the resulting diluted chemical reagent will be. A solvent such as water can be added before or after the bursting operation. The spray bottle dispensers are preferably filled with diluted chemical reagent by the bottler containing the plurality of reservoirs 314 to allow numerous recharging operations.
A fifth embodiment of a spray bottle dispenser 400 according to the present invention is shown in FIGS. 15 to 17. The spray bottle dispenser 400 comprises a spray head portion 402 and a bottle portion 404. The spray head portion 402 includes a threaded coupler 406 for connecting the spray head portion 402 to a threaded neck of the bottle portion 404. A downtube 408 is connected to the spray head portion 402, and extends down to the bottom portion of the bottle portion 404.
In this fifth embodiment, a plurality of donut-shaped chemical reservoirs 410 are provided on the downtube 408. Specifically, the donut-shaped chemical reservoirs 410 each have a center hole 412 through which the downtube 408 passes. The chemical reservoirs 410 are provided with a metal foil 414 for sealing an upper end of the chemical reservoir 410 for containing the chemical reagent liquid L, as shown in
In use, the spray bottle dispenser 400 is initially filled by the bottler with dilute chemical reagent and sold at the point-of-sale. After the initial consumption of the diluted chemical reagent, a user unscrews the spray head portion 402 from the body portion 404 and lifts the downtube 408 from the bottle portion 404. The user then grips the lowermost reservoir 410 and simply pulls it off the end of the downtube 408, and then punctures the metal foil 414 with an instrument, in particular the tip of the downtube 408. The punctured reservoir 410 is dropped into the bottle portion 410. A solvent such as water is added to the bottle portion 404 before or after the step of puncturing the reservoir 410. The spray bottle dispenser 400 is then reassembled by screwing the spray head portion 402 onto the bottle portion 404.
Another embodiment of a donut-shaped chemical reservoir 410′ is shown in
A sixth embodiment of a spray bottle dispenser utilizes insert 500 as shown in FIGS. 18 to 21. The insert 500 comprises a cylinder portion 502 having a lip portion 504, a connector portion 506 connecting the cylinder portion 502 to an upper reservoir 508, a connector portion 510 connecting the upper reservoir 508 to a middle reservoir 512, and a connector portion 514 connecting the middle reservoir 512 to the lower reservoir 516. A downtube 518 is shown passing through the hollow cylinder portion 502, however, is not connected to the insert 500.
The reservoirs 508, 512 and 516 are in a stacked and stepped arrangement. The upper reservoir 508 is thinner in width and deeper in depth compared with the lower reservoir 516. The middle reservoir 512 has dimensions between those of the upper reservoir 508 and lower reservoir 516. This stepped and stacked arrangement allows access by an instrument to puncture sealing membranes (not shown) sealing each reservoir 508, 512, 516 while the insert remains in the bottle portion of the spray bottle dispenser.
A seventh embodiment of a spray bottle dispenser having an insert 600 is shown in
In use, the spray bottle dispensers are filled with diluted chemical reagent initially by the bottler, and the downtube is passed only through the cylinder portion 602. After consumption of the initial diluted chemical reagent, the user withdraws the downtube above the level of the upper reservoir 612, and forces the tip of the downtube through the upper metal foil 520 and lower metal foil 622 of the reservoir 510 releasing the chemical concentrate liquid into the bottle portion. A solvent such as water is added before or after the step of accessing the chemical concentrate liquid. After puncturing the metal foil 520 and 622, the downtube is lifted upwardly and then passed between the cylinder portion 602 and the side of the reservoir 610. Alternatively, the downtube can be threaded through the reservoir 610 and down along the side of the middle reservoir 614 so as not to puncture the chemical reservoir 614. The connector portion 608, 612 and 616 are substantially flexible enough to act as hinges to move the lower reservoirs out of the way so as not to be punctured by the downtube during the insertion operation of the downtube.
In an alternative embodiment, only the upper portion of each reservoir is provided with a membrane that can be punctured with the bottoms being molded portions of the reservoirs, and not readily subject to being punctured.
In an eighth embodiment, a mechanical coupler 700 is connected to an insert 702. The insert 702 is identical to the insert shown in
This arrangement provides four (4) portion 710 to allow water poured through the center of the mechanical coupler 700 to pass through and out the ports 710 into the bottle portion when recharging the spray bottle dispenser with this arrangement.
This arrangement allows the insert 702 to be extruded continuously, since no lip need be molded in the insert 702. The insert 702 is provided with upper and lower sealing membranes (not shown) and then attached to the mechanical coupler 700 during assembly. Thus, the insert 702 can be cut from a continuous length of material extruded at high speed, filled with chemical concentrate, sealed with the sealing membranes at both ends, and then assembled with the mechanical coupler 700 to finish complete assembly.
A preferred spray bottle dispenser 800 is shown in
An insert 816 disposed within the assembled spray bottle dispenser 800, as shown in
The bayonet device 818, washer 824 and insert 816 are all slidable along the downtube 804 to allow assembly of the spray bottle dispenser 800. Preferably, the through hole in the washer 820 is held fairly tightly (e.g., slight interference fit) on the downtube 804 so that it can be positioned at an upper portion of the downtube 804, and will not slip easily from this position once assembled. The through holes in the washer 824 and insert 816 can be slightly oversized to facilitate easy assembly and venting of air from the spray head 802 into the spray bottle 808.
The spray bottle dispenser 800 is assembled by inserting the downtube 804 into the spray head 802, and then sliding in the bayonet device 818, washer 824 and insert 816 onto the downtube 804. This subassembly shown in
The details of the insert 816 are shown in
The reservoirs 826a, 826b, 826c, 826d, are defined by different wall portions of the insert 816. Specifically, the insert 816 includes an outer cylindrical portion 816a divided into four (4) sections by ribs 816b connecting to an inner cylindrical portion 816c. The upper ends of the reservoirs 826a, 826b, 826c, 826d are open while the lower ends of the reservoirs are closed by a bottom wall portion 816d, as shown in
The upper ends of the reservoirs 826a, 826b, 826c, 826d are sealed by a sealing membrane 828, as shown in
The bottom of each reservoir 826a, 826b, 826c, 826d are formed closed, and are defined by bottom wall portion 816d integrally molded as part of the insert 816, as shown in
The insert 816 shown in
In the alternative embodiment shown in
An embodiment of the bayonet device 818 is shown in
In an alternate embodiment shown in
In this embodiment, the washer portion 820′ can be made of different material from the bayonet portion 822′, for example, the washer portion 820′ can be made of injection molded plastic material while the bayonet portion 822′ can be made of a composite fiberglass material to provide additional strength and sharpness of the tip 822a′. Alternatively, the bayonet portion 822′ can be made from extruded plastic material. In the situation of the bayonet portion 822′ being extruded, the entire length of the bayonet portion 822′ can be fluted or serrated to provide a plurality of peripheral grooves along the length thereof to facilitate drainage of chemical concentrate (i.e., prevent sealing) between the tip 822a′ and the bottom wall portion 816d of one of the reservoirs 826a, 826b, 826c, 826d.
Various tip designs of the bayonet 822 are shown in
The venting arrangement of a conventional spray head and spray bottle should be maintained with use of the insert 816 according to the present invention. Specifically, a conventional spray head vents air back into the spray bottle to compensate for liquid being withdrawn from the spray bottle during use. Otherwise, as the spray bottle is evacuated, a vacuum condition will be created therein making suction of the liquid through the downtube more difficult or impossible.
The conventional spray head is provided with an air passageway to vent air in an upper neck portion of the spray bottle. The insert according to the present invention could potentially interfere with venting when used with a conventional spray head and conventional spray bottle, since the insert is essentially a plug in the upper neck portion of the spray bottle.
The insert 816, bayonet device 818 and washer 824 can all be designed to facilitate venting, however, it has been found during experimental use that even small micro cracks through or between these components is satisfactory for venting the spray bottle without purposely designing venting features in these components. For example, the through hole 828 in the insert 816, shown in
The insert 816 can be provided with additional modifications and designs for use in various applications and with various conventional and non-conventional spray head and spray bottle components. The insert 816″ shown in
Alternatively, the insert 816 shown in
The insert 816 according to the present invention can be manufactured, marketed and sold as a separate product unit as opposed to an entire spray dispensing apparatus 800 of the type shown in
When the insert 816 is manufactured, marketed and sold as a separate stand alone unit, any leakage from the insert will be exterior to the insert. For instance, the sealing membrane 828 in some embodiments (e.g., metal foil) is somewhat susceptible to easy puncture or damage which could cause inadvertent spillage or contamination. Further, any leakage from the insert of the chemical concentrate could cause damage to packaging or damage to other commercial or other household products and/or facilities storing such an insert. Most important, any spillage could be a personal hazard, in particular to children, who could inadvertently come into contact with or even ingest chemical concentrate causing serious injury or potentially death. Thus, it is preferred to provide an additional sealing or protecting means to an upper portion of the insert or encompassing the entire insert, particularly for consumer use. For example, the insert can be blister packed or packaged in a manner so that the insert is fully encompassed by sealed packaging. Alternatively, only the upper portion of the insert 816 is further protected. For example, as shown in
As shown in
A preferred embodiment of the present invention is directed to a spray dispensing apparatus having an insert and the insert itself. The insert is provided with at least one reservoir for containing chemical concentrate. In a preferred embodiment, the insert is provided with multiple reservoirs for containing separate charges of chemical concentrate.
In the preferred embodiment having multiple separate reservoirs, the insert according to the present invention can be provided with chemical concentrate of the same concentration or chemical concentrate of different concentrations. Further, different chemical compositions can be contained in the separate reservoirs for providing various chemical mixtures. In a preferred embodiment, two or more different reactive chemicals are stored in separate reservoirs that can be both ruptured to allow mixing of these chemicals with or without water initially to form a reactive chemical mixture. Storage of chemicals in this manner ensures freshly reacted chemicals having the highest level of activities. Performance chemicals ranging from applications for personal care, surface cleaners, disinfectants, insecticides and other known classes of chemical compounds that can be formed by mixing two or more different charges of chemicals together can be dispensed with the spray dispensing apparatus and insert according to the present invention.
Other configurations of the spray bottle dispenser are shown in
A cap device 900 can be used with a one-neck spray bottle or multiple-neck spray bottle to provide at least one dose or charge of chemical concentrate into the spray bottle. As shown in
The bottom end of the upper cap portion 902 is provided with a sealing membrane 906 to seal the lower ends of the reservoirs 904a, 904b. The lower cap portion 904 is provided with a frangible bottom wall portion 904a provided with a peripheral groove 904b to provide a breakable wall portion.
The bottom wall portion 904a is provided with protrusions 904c, preferably sharpened, which will puncture and rupture the sealing membrane 906 when the upper cap portion 902 is further driven downwardly into the lower cap portion 904. Upon further driving the upper cap portion 902 downwardly into the lower cap portion 904, the lower edge of the upper cap portion 902 will cause the bottom wall portion 904a to break away and release the chemicals into a spray bottle to which the cap 900 is applied. A center rib 908 separates the one reservoir 904a from the other reservoir 904b.
The cap 900 is inserted into a neck portion of a spray bottle. Specifically, the lower cap portion 904 is received in the neck portion with the upper flange 904a resting on the upper edge of the neck portion of the spray bottle. The inner threads 902a of the upper cap portion 902 engage with the external threads of the neck portion of the spray bottle to force the upper cap portion 902 downwardly into the lower cap portion 904. The sealing membrane 906 is forced into the protrusions 904c causing the two reservoirs 904a and 904b to rupture releasing chemical. As the upper cap portion 902 is further rotated, the lower edge of the upper cap portion 902 is rammed into the frangible bottom wall portion 904a of the lower cap portion 904 causing it to break and release chemical into the spray bottle.
Another embodiment of a cap device 900′ is shown in
In an alternative embodiment shown in
An alternative to the bayonet device 818 is shown in
The bayonet portion 1002 is designed or configured to compromise the bottom of the cartridge 816 in a manner to puncture at least one reservoir of the cartridge 816. Alternatively, multiple bayonet portions 1002 can be provided extending upwardly from bottom wall portion 1000d at different locations (e.g. at 180 degrees, 90 degrees) to simultaneously puncturing two (2), three (3), four (4) or more reservoirs of the cartridge 816. Alternatively, the multiple bayonet portions 1002 can have different heights to selectively puncture one reservoir by forcing the cartridge 816 into the cartridge receiver 1000 to a first extent, and then puncture another reservoir at a time interval later to puncture a second reservoir by forcing the cartridge 816 further into the cartridge receiver 1000 to a second extent.
The method of puncturing the bottom of the cartridge 816 must be sufficient to cause adequate release (e.g. drainage) of the cartridge. In the case of a liquid, the puncture must allow some venting of the puncture reservoir of the cartridge 816. This can be accomplished by providing the bayonet portion 1002 with various tip designs (See FIGS. 36 to 39), slightly rotating (e.g. back-and-forth) the cartridge 816 in the cartridge receiver 1000 to increase the size of the puncture hole, and/or providing a through hole in the bayonet portion 1002. In different embodiments of the cartridge 816, puncturing occurs through a foil, film or other type of end seal of the cartridge 816, or through the plastic molded bottom of the cartridge 816. In a further alternative, the bayonet portion 1002 may be a separate piece (e.g. made of metal to further facilitate cutting or puncturing) rather than the integral molded bayonet portion 1002 shown in
The cartridge receiver 1000 can be provided in the neck portion of a single neck bottle. In a multiple neck bottle, one or more cartridge receivers 1000 can be provided in one or more neck portions. In the embodiment shown in
In another embodiment, the cartridge receiver 1000 is provided through a wall portion of the bottle 808, as shown in
The cartridge 816A shown in
The upper end of the cartridge 816B is provided with a sealing membrane 828 while the lower end of the cartridge 816B has an integrally molded bottom portion. In the embodiment shown in
In a further embodiment shown in
In an even further embodiment shown in
The cartridge and cartridge receiver can be configured to provide a key arrangement. Specifically, the cartridge and cartridge receiver can be keyed in such a manner so that only a specific configuration of a cartridge can be fit into a specific configuration of a cartridge receiver. The key arrangement can be utilized, for example, to allow only one type of chemical to be used in one type of bottle (e.g. color coded bottles and cartridges to indicate type of chemical and/or cleaning use). The key arrangement can also be utilized for marketing purposes to eliminate competitors from using bottles and/or cartridges providing an exclusive product or product lines. The keying arrangement can be utilized with different size and/or shape cartridges and/or cartridge receivers or neck portions to provide the same effect or other related effects.
As shown in
The dispenser according to the present invention is particularly suitable for storing multiple separate quantities of substances, in particular concentrated substances. The substance or concentrated substances can be provided in various forms including pills, tablets, wafers, vials, balls (e.g. like paint balls), separate containers, bubble packs, blister packs, test tubes, and other forms or containers. The substance or concentrated substance can be solids, liquids, gases, solutions, powders, micro encapsulate substances, slurries, pastes, multi-phase mixtures or solutions, granules and other phases and/or states.
As shown in
The cartridge 1102 is provided with an upper seal 1106 to seal the contents of the cartridge from air, moisture and contamination during storage, shipment and use. Alternatively, or in addition, a removable cap seal is provided for sealing the opening into the cartridge 1102. The seal can be made from a variety of materials including foils, films, multi-layer films, papers, cardboards, laminations, composite materials, and other suitable materials. The tablets 1104 are shown stacked in contact with each other, however, the tablets 1104 can optionally be individually wrapped or package to further preserve the tablets and prevent the tablets from sticking together for some applications of various chemical compositions. Further, the tablets 1104 can be replaced by thinner wafers of a more concentrated chemical substance to increase the number of separate charges contained in the cartridge 1102 to provide a greater number of recharges of the spray bottle dispenser.
A desiccator 1108 may also be supplied to maintain a moisture free environment within the cartridge 1102. The desiccator 1108 can be a separate unit, or can be incorporated into a cap seal for the cartridge 1102. The desiccator 1108 is shown at the top of the cartridge 1102, however, it can be located at other positions inside the desiccator, and other separated desiccators can be added to effectively maintain a moisture free environment inside the cartridge 1102.
A user operates the spray bottle dispenser by removing the cap 814 and film 1106 (partially or fully), and then removing one or more tablets 1104 from the cartridge 1102. The user can decide to use one, two or more tablets to selectively vary the concentration of working mixture desired depending on various applications. For example, for a glass cleaner one tablet is used in making the solution while in the case of a surface cleaner two tablets are used in making the solution. The one or more tablets 1104 can be removed by tilting the spray bottle 808, or in the case of a removable cartridge configuration, the cartridge 1102 can be removed from the second neck portion 812 and then tilted itself. After removing one or more tablets 1104, the cartridge 1102 is sealed by the cap 114, or in addition, a seal (e.g. sticky back foil or film) or sealing device (e.g. cap or cork) can be utilized to ensure a good seal. The tablets can be added through the first neck portion 810 (i.e. after removal of spray head 802) and/or through the second neck portion along with diluent such as water depending on whether the cartridge 1102 is removable or non-removable from the second neck portion 810.
In another embodiment of a cartridge 1202, as shown in
Another embodiment of the container 1204′, as shown in
During use, the container 1204′ can be loaded through the first neck portion 810 or second neck portion 812 of the spray bottle 808. When a diluent such as water is added to the spray bottle 808, before or after loading the container 1204′ into the spray bottle 808, the diluent enters into the container 1204′ through the screen portions 1204c′ and 1204d′ to dissolve the chemical concentrate 1204e′.
The cartridge system according to the present invention can be utilized to charge and recharge numerous types of containers and dispensers.
As shown in
The container 1300 is provided with a cartridge 1306. The cartridge 1306 is the same or similar to the cartridge embodiments shown in
A particularly suitable embodiment of a cartridge system according to the present invention for charging and recharging containers and dispensers is shown in
The cartridge 1306 shown in
The bottom wall 1308a of the cartridge receiver 1308 is provided with a “reverse” oriented bayonet 1308b and a through hole 1308c. In addition, a seal 1308d (e.g. foam, paper, card board, film, composite layer) is provided in the bottom of the cartridge receiver 1308.
The through hole 1308c in the bottom wall 1308d of the cartridge receiver 1308, for example, can have the shape of a secant, as shown in
The bayonet 1308b is located in the remaining one-eighth (⅛) portion of the same quadrant portion as the opening 1308c, which is aligned with one of the four quadrant reservoirs of the cartridge 1308. The remaining three (3) quadrant portions of the bottom wall 1308a are closed (i.e. not open) so as to provide a second seal by means of the seal 1308d located in the bottom of the cartridge receiver 1308. Specifically, the seal 1308d biases against the seal 1310 of the cartridge 1306 when the cartridge 1306 is fully inserted into the cartridge receiver 1308. The seal 1308d provides a second seal, but also forces against the existing seal 1310 to maintain the integrity of seal 1310 with the edge and reservoir landings existing at the one end of the cartridge 1306. This arrangement, allows the cartridge 1306 to be maintained in the orientation shown in
The cartridge 1306 is provided with an upper flange 1306a having four (4) indents 1306b at a lower edge thereof to provide fingernail or thumb nail gripping points to facilitate removal of the cartridge 1306 from the cartridge receiver 1308. In addition or alternatively, the length of the cartridge 1306 and the length of the cartridge receiver 1308 can be selected so that the upper flange 1306a of the cartridge 1306 is slightly separated from the upper flange 1308e of the cartridge receiver 1308 (See
In an embodiment of the container 1300 utilizing both the cartridge 1306 and cartridge receiver 1308, the container 1300 is filled or refilled by removing cap 1304 and cartridge 1306, if one is already installed. A diluent such a water is poured through the cartridge receiver 1308 into the container 1300. Specifically, the diluent such as water passes through the through hole 1308c in the bottom wall 1308a of the cartridge receiver 1308. The existing cartridge 1306 or a new cartridge 1306 is fitted into the cartridge receiver 1308. When the cartridge 1306 is forced downwardly within the cartridge receiver 1308, the bayonet 1308b punctures the foil or film seal 1310 of one of the quadrant reservoirs. The user can slightly rotate the cartridge 1306 back-and-forth to increase the size of the puncture hole through the foil or film seal 1310 to ensure adequate drainage of the contents of the quadrant reservoir into the container 1300 to then mix with the diluent such as water. The solution can be agitated, for example, by shaking the container 1300.
The solution can be poured from the container 1300 for use by either removing the cartridge 1306 or removing the assembly of cartridge 1306 and cartridge receiver 1308. Alternatively, one quadrant of the cartridge 1306′ can be provided with a dummy reservoir and molded as a quadrant-shaped through passageway 1306c′ open on both ends, as shown in
In a one (1) reservoir cartridge system, the cartridge is removed from the cartridge receiver after the contents are drained to allow solution to be pour from the bottle through the cartridge receiver. In other alternative arrangement, both ends of the cartridge are provided with foil or film seals, which would allow one or more through passageways to be formed through the cartridge by breaking and removing the seal portions for each end for one or more reservoirs.
