A flexible closed plastic pouch forming an expulsion means for supplying dispensing pressure, holding a product, closed by an aerosol valve. A plurality of pocket members disposed at spaced positions within said pouch with their openings facing the interior of the pouch. Each pocket member having an extension of a predetermined length attached at its end to the interior of first of two facing wall members of the pouch. Each pocket member enclosing a predetermined quantity of first component of a two-component gas generation system and being releasably closed by one of a plurality of closure members, each of said closure members having an extension of a predetermined length attached at its end to the interior of the second of the two facing walls of the pouch. The pouch contains a second component of said two-component gas generation system and a starting means encapsulated within a delay means or device to initially generate a predetermined quantity of pressurizing gas after a delay of a predetermined period of time. The pressurizing gas inflates and expands the pouch within the container under pressure. Due to the dispensing of the product, the pouch expands further and causes sequential separation of the pocket members from their closure members and serial opening of each pocket member to add predetermined quantities of aliquot of the first component to the second component and further generate additional quantities of pressurizing gas. The internal pressure within the container is maintained substantially within a range of predetermined maximum and minimum pressure levels until dispensing the product from the container is complete, at which time, the walls of the pouch substantially lining the interior of the container. A device inside the container prevent the pouch from expanding before the product is filled into the container.

Ready to fill pressurized dispenser and method

A flexible closed plastic pouch disposable within a container holding a product for supplying dispensing pressure therein. A plurality of pocket members disposed at spaced positions within said pouch with their openings facing the interior of the pouch. Each pocket member having an extension of a predetermined length attached at its end to the interior of first of two facing wall members of the pouch. Each pocket member enclosing a predetermined quantity of first component of a two-component gas generation system and being releasably closed by one of a plurality of closure members, each of said closure members having an extension of a predetermined length attached at its end to the interior of the second of the two facing walls of the pouch. The pouch contains a second component of said two-component gas generation system and a starting component encapsulated within a delay device to initially generate a predetermined quantity of pressurizing gas after a delay of a predetermined period of time. The pressurizing gas inflates and expands the pouch within the container under pressure. Due to the dispensing of the product, the pouch expands further and causes sequential separation of the pocket members from their closure members and serial opening of each pocket member to add predetermined quantities of aliquot of the first component to the second component and further generate additional quantities of pressurizing gas.

Regulated pressurized dispenser and method

A flexible closed plastic pouch disposable within a product container for supplying dispensing pressure therein. A plurality of pocket members disposed at spaced positions within said pouch with their openings facing the interior of the pouch. Each pocket member having an extension of a predetermined length attached at its end to the interior of first of two facing wall members of the pouch. Each pocket member enclosing a predetermined quantity of first component of a two-component gas generation system and being releasably closed by one of a plurality of closure members, each of said closure members having an extension of a predetermined length attached at its end to the interior of the second of the two facing walls of the pouch. The pouch contains a second component of said two-component gas generation system and a starting device encapsulated within a delay device to intially generate a predetermined quantity of pressurizing gas after a delay of predetermined period of time. The pressurizing gas inflates and expands the pouch within the container under pressure. Due to the dispensing of the product, the pouch expands further and causes sequential separation of the pocket members from their closure members and serial opening of each pocket member to add predetermined quantities of aliquot of the first component to the second component and further generate additional quantities of pressurizing gas. The internal pressure within the container is maintained substantially within a range of predetermined maximum and minimum pressure levels until dispensing the product from the container is completed.

A flexible enclosed plastic bag disposable in a product container for supplying dispensing pressure therein. The bag contains an envelope having its outer sides permanently attached to the respective inside walls of the bag. One of the sides of the envelope has one of a two component gas generating system disposed in a plurality of aligned pocket members formed therein with their openings facing the other side of the envelope, the latter being releasably adhered to the first mentioned side to enclose one component in the pockets. The bag contains the second component and a starting means to initially generate gas and expand the bag and develop product dispensing pressure within the container. As the product is dispensed, expansion of the bag causes sequential separation of the sides of the envelope and serial opening of the pockets to add aliquots of the first component to the second component and further generate gas and maintain said pressure in the container until substantially all of the product is dispensed from the container. The radio-activity at the surface of said dispenser and of its component parts and accessories as well as that of the product discharged therefrom does not exceed 0.1 milliroentgen per hour at the time of manufacturing.

Pressure generating apparatus and method

A packaging device consisting of at least one enclosure containing the product and at least one flowable material of predetermined quantity, closed by at least one airtight closure, at least one portion of the walls of said enclosure and closure is flexible. In the event the product is tampered with through an opening in the walls of said packaging device, the package will manifest evidence which will alert the consumer of the possibility that the product may have been tampered with. Statements for identifying evidence of tampering with the package and cautioning the purchaser against utilizing the contents therein appear on said package.

Tamper resistant packaging device and closure

An inner enclosure of a predetermined size, design and construction loaded with a product and pressurized with a flowable material before said inner enclosure is closed, said inner enclosure is enclosed within a flexible outer enclosure, and said outer enclosure is closed after its internal pressure is reduced below that of the surrounding atmospheric pressure. In the event the product is tampered with through apertures in the walls of the package, the package will manifest evidence which will alert the consumer of the possibility that the product may have been tampered with.
