Definitions
- prior aerosol type dispensers generally were operable only in an upright condition, otherwise premature exhaustion of the dispensing medium would result with a substantial loss of usable product which would remain indispensable in the container due to loss of dispensing pressure.
- Prior dispensers also had other deficiencies such as temperature sensitivity, non-uniform dispensing pressure, limited shelf-life, unreliability, difficulty of manufacture and relatively high cost of manufacture.
- the present invention provides a dispensing mechanism which overcomes the above-mentioned deficiencies of the prior art devices and provides additional novel features and advantages, and a wider range of uses, than were possible with devices used heretofore.
- a pressurized dispensing container containing an expansible bag capable of being inflated to force out the product disposed in the container externally of the bag.
- the bag is divided into a plurality of expansible chambers or compartments serially arranged and separated from each other by disruptable transverse partitions which are attached at each end on the bag wall and extend across the bag. These partitions separate the bag into a series of individual compartments which contain one component of a two-component gas generating mixture.
- One compartment begins to generate pressure gas after a predetermined period of time through addition of a delaying agent to the one gas generating component.
- the present invention overcomes the above- mentioned deficiencies and provides a dispensing container with novel features and advantages and a wider range of uses than the devices of the prior art.
- Expulsion means for developing and maintaining relatively constant gaseous dispensing pressure in a container from which a product is to be dispensed, comprising an enclosed, fluid impermeable flexible plastic pouch disposed within the container, and having a pair of facing wall members.
- a plurality of pocket members are disposed within the pouch in spaced relation to one another and affixed to the interior of one of said wall members.
- a closure member is associated with the interior of the other wall member and releasably closes each of said pocket members.
- Each pocket member contains a first component, e.g., sodium bicarbonate, of a two-component carbon dioxide gas generation mixture.
- the second component e.g., citric acid solution
- the second component e.g., citric acid solution
- Starting delay means e.g., a rupturable or dissolvable capsule containing sodium bicarbonate and/or lithium carbonate is disposed within the pouch in contact with the second component for causing the initial generation of carbon dioxide gas after a prescribed period of time and each pocket member is sequentially severable from the closure member to thereby empty its contents into admixture with the second component to generate more gas as the pouch expands due to the dispensing of the product from the container.
- Container 10 has a cylindrical body or sidewall 11, inwardly dished bottom 12 and bell- shaped top 13 in which is mounted a conventional spring loaded aerosol spray valve assembly 14.
- Container 10 and its component parts just described can be fabricated from any suitable material such as thin gauge aluminum or other metal, or even plastic depending on the product to be dispensed and any governing safety specifications that might be involved.
- Valve assembly 14 is also of conventional design having plunger and spray head 15 carrying spray orifice 16, suitably constructed of plastic, and internal parts (not shown) such as a spring, ball valve and mounting ring 17 and bottom intake member 18 which may be of metal and/or plastic consistent with the previously mentioned requirements.

Also affixed to inner surface 24 of sidewall 11 and extending longitudinally there along is a perforate tube member 25 having a plurality of holes 26 at spaced positions around and along said tube member 25.
- the function of barrier member 22 and tube member 25 is to insure trouble-free operation of the dispenser and prevent expulsion assembly 20, as it expands in the manner to be described, from blocking off or plugging the interior of the container either laterally/circumferentially or plug- 'ging off the valve bottom intake member 18.
- Expulsion assembly as shown is disposed within container 10 without being attached or anchored to container 10, although it may, if desired be so connected.
- Assembly 20 is comprised of generally rectangular envelope, bag or pouch 27 which is constructed of a flexible, fluid impermeable plastic such as, for example, polyethylene or polypropylene and may be fabricated from a sheet of plastic by folding it into overlaid halves which are then sealed or adhered by suitable means along their respective contacting side forming a first wall member 27a and a second wall member 27b of the pouch 27.

Description
- For a long time there has been a need for a pressure generating system for use in product dispensing containers that is isolated from, and is not dispensed with, the product. This need has been partially due to environmental considerations but also for safety precautions, avoidance of product contamination or dilution as well as skin toxicity and/or irritation.
- Furthermore, prior aerosol type dispensers generally were operable only in an upright condition, otherwise premature exhaustion of the dispensing medium would result with a substantial loss of usable product which would remain indispensable in the container due to loss of dispensing pressure.
- Prior dispensers also had other deficiencies such as temperature sensitivity, non-uniform dispensing pressure, limited shelf-life, unreliability, difficulty of manufacture and relatively high cost of manufacture.
- The present invention provides a dispensing mechanism which overcomes the above-mentioned deficiencies of the prior art devices and provides additional novel features and advantages, and a wider range of uses, than were possible with devices used heretofore.
- In the U.S. patent No. 3,178,236 there is described a pressurized dispensing container containing an expansible bag capable of being inflated to force out the product disposed in the container externally of the bag. The bag is divided into a plurality of expansible chambers or compartments serially arranged and separated from each other by disruptable transverse partitions which are attached at each end on the bag wall and extend across the bag. These partitions separate the bag into a series of individual compartments which contain one component of a two-component gas generating mixture. One compartment begins to generate pressure gas after a predetermined period of time through addition of a delaying agent to the one gas generating component. Expansion of that compartment disrupts the associated partition releasing a further portion of the one gas generating component to generate more gas and maintain the pressure within the container. In this way, one partition after the other is disrupted until the bag is fully inflated and substantially all of the product is displaced out of the container.
- However, this method of pressurization of a container has a serious drawback. It is very difficult to fabricate the expansible bag with its compartments and transverse partitions, even if the partitions are in the form of adhered portions of the sidewalls of the bag as suggested in a further embodiment. Thus, the problem raised to provide an improved dispensing container with a bag or pouch which can be produced easierly and more efficiently.
- The present invention overcomes the above- mentioned deficiencies and provides a dispensing container with novel features and advantages and a wider range of uses than the devices of the prior art.
- Expulsion means for developing and maintaining relatively constant gaseous dispensing pressure in a container from which a product is to be dispensed, comprising an enclosed, fluid impermeable flexible plastic pouch disposed within the container, and having a pair of facing wall members. A plurality of pocket members are disposed within the pouch in spaced relation to one another and affixed to the interior of one of said wall members. A closure member is associated with the interior of the other wall member and releasably closes each of said pocket members. Each pocket member contains a first component, e.g., sodium bicarbonate, of a two-component carbon dioxide gas generation mixture. The second component, e.g., citric acid solution, of said two-component carbon dioxide gas generation mixture is disposed within the pouch and externally of said enclosed pocket members. Starting delay means, e.g., a rupturable or dissolvable capsule containing sodium bicarbonate and/or lithium carbonate is disposed within the pouch in contact with the second component for causing the initial generation of carbon dioxide gas after a prescribed period of time and each pocket member is sequentially severable from the closure member to thereby empty its contents into admixture with the second component to generate more gas as the pouch expands due to the dispensing of the product from the container.
