A composte container having an outer support and an inner liner surrounding the space within the container and top and bottom rigid gas impervious cover means adapted to be seamed onto the container for cooperating with said liner to seal the contents placed in the storage space within the structure, comprising a fibrous tubular member having a generally circular cross-section defined by exterior and interior walls and forming an open ended outer support member, a tubular shrinkable plastic barrier film inner liner fitted within the support member with a portion thereof extending beyond at least one of the ends of said tubular member, said liner being flexible and impervious to gas flow, said liner being sealed at one end and having said other open end extending from within the support member and beyond an open end of the support member to define the mouth of the tubular liner, a portion of the mouth of said liner that extends beyond the support member being folded over and around to overlap the exterior wall of the support member at said one end of said at least one of the ends of said support, the overlapped portion of the liner being heat shrunk to be wrinkle-free and tightly conforming to the exterior surface of the support member at said one end thereof, said heat shrunk overlapped portion of the mouth of the liner forming a plastic ring integral with that open end of the support member, said ring forming a smooth seat for cooperating with the top cover means seamed to the support member over said ring to seal the mouth of the liner, the bottom cover means being crimped to the other end of the support member, said plastic liner being supported within the fibrous member having a product stored within the liner which together with the cover means seamed to the support member over the ring forms a gastight impervious container enclosing the storage space for the product to protect such product when there is a difference in pressure between the storage space within the container and the pressure on the outside thereof.

A composte container having an outer support and an inner liner surrounding the space within the container and top and bottom rigid gas impervious cover means adapted to be seamed onto the container for cooperating with said liner to seal the contents placed in the storage space within the structure, comprising a fibrous tubular member having a generally circular cross-section defined by exterior and interior walls and forming an open ended outer support member, a tubular shrinkable plastic barrier film inner liner fitted within the support member with a portion thereof extending beyond at least one of the ends of said tubular member, said liner being flexible and impervious to gas flow, said liner being sealed at one end and having said other open end extending from within the support member and beyond an open end of the support member to define the mouth of the tubular liner, a portion of the mouth of said liner that extends beyond the support member being folded over and around to overlap the exterior wall of the support member at said one end of said at least one of the ends of said support, the overlapped portion of the liner being heat shrunk to be wrinkle-free and tightly conforming to the exterior surface of the support member at said one end thereof, said heat shrunk overlapped portion of the mouth of the liner forming a plastic ring integral with that open end of the support member, said ring forming a smooth seat for cooperating with the top cover means seamed to the support member over said ring to seal the mouth of the liner, the bottom cover means being crimped to the other end of the support member, said plastic liner being supported within the fibrous member having a product stored within the liner which together with the cover means seamed to the support member over the ring forms a gastight impervious container enclosing the storage space for the product to protect such product when there is a difference in pressure between the storage space within the container and the pressure on the outside thereof.
Claim 3
Dependent Claim
196 words
A container as in claim 1 wherein said plastic liner also includes another tubular plastic barrier seal liner element sealed at one end collapsed like an accordian within said support and having an open end extending beyond the other open end of the support member, said extending end of said another liner being folded over and around to overlap the exterior wall of the support member at said other end, the overlapped portion of said another liner being heat shrunk to be wrinkle-free and tightly conforming to the exterior surface at said other end of the support member to form a second plastic ring integral with that open end of the support member, said first tubular plastic barrier seal supporting a body of liquid therein, a bottom cover seamed to said second plastic ring, means to produce a body of compressed air within said collapsed another liner, nozzle means having a valve therein communicating with the body of liquid in said first tubular liner whereby the liquid may be dispensed through the nozzle when the valve is opened and the liquid is pushed from said liner as the compresed air in said another liner expands therein.
