Abstract
Abstract A container (20) made of a rigid tubular conformation, each end (21, 22) of which is flattened to produce and provide outwardly protruding edges (25). A transition portion (33) between the flattened end portion (22) and undeformed body portion has a sloped wall in which at least one access aperture (24) is formed. The aperture (24) is selectively closed by a plug, valve or cap adapted to be secured in a fluid-tight manner in this container (20). Hand hold apertures (e.g., 23) may be formed where the ends are sealed. Disposable or reusable bladders, bags and/or liners (58, 70) can be used with these containers, and can be extended out of the fitting (50, 72) and can be gathered together and sealed (59) to provide a sanitary and tamper-proof covering. The container (20) may be pressurized if desired. An expanding plug assembly (100) having a body (102) formed of a pair of resilient members (104, 106) separated by a thin plate or diaphragm (108) also forms a part of this invention.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
163 words
A plug assembly for sealing an aperture in a rigid member, said plug assembly including inner and outer rigid compression plates and a plug body between said plates, characterized in that said plug body includes a pair of resilient members and a separating member located between said resilient members, said resilient members being capable of expanding radially in a direction substantially perpendicular to the space between the inner and outer rigid compression plates when said inner and outer rigid compression plates are moved toward each other, said separating member including opposed substantially planar surface means frictionally engaging confronting substantially planar surfaces of the pair of resilient members for impeding radial expansion of the resilient members in the region of the separating member when said outer and inner compression plates are moved toward each other, and means for moving said inner and outer compression plates toward each other for causing maximum radial expansion of said resilient members in regions spaced from the confronting surfaces.
Claim 2
Dependent Claim
163 words
A plug assembly for sealing an aperture in a rigid member, said plug assembly including inner and outer rigid compression plates and a plug body between said plates, characterized in that said plug body includes a pair of resilient members and a separating member located between said resilient members, said resilient members being capable of expanding radially in a direction substantially perpendicular to the space between the inner and outer rigid compression plates when said inner and outer rigid compression plates are moved toward each other, said separating member including opposed substantially planar surface means frictionally engaging confronting substantially planar surfaces of the pair of resilient members for impeding radial expansion of the resilient members in the region of the separating member when said outer and inner compression plates are moved toward each other, and means for moving said inner and outer compression plates toward each other for causing maximum radial expansion of said resilient members in regions spaced from the confronting surfaces.
Claim 3
Dependent Claim
15 words
The plug assembly of claim 1 characterized in that said separating member is substantially non-compressable.
Claim 4
Dependent Claim
18 words
The plug assembly of claim 2 characterized in that said separating member is thinner than the resilient members.
Claim 5
Dependent Claim
38 words
The plug assembly of claim 1 characterized in that said resilient members and separating member are substantially circular in plan view and wherein the diameter of the resilient members is greater than the diameter of the separating member.
Claim 6
Dependent Claim
31 words
The plug assembly of claim 4 characterized in that the diameter of the separating member is approximately 25% smaller than the diameter of the resilient members, as measured in plan view.
Claim 7
Dependent Claim
21 words
The plug assembly of claim 1 characterized in that each of said resilient members is of the same material and dimensions.
Claim 8
Dependent Claim
70 words
The plug assembly of claim 1 wherein said pair of resilient members includes an outer resilient member adjacent the outer rigid compression plate, said outer rigid compression plate including a peripheral surface overlying side surfaces of said outer resilient member for engaging an outer surface of a container when said plug assembly is inserted into an aperture in said container, for aiding in positioning the plug assembly within said aperture.
Claim 9
Dependent Claim
278 words
The combination of a plug assembly and container, said container having a wall with an aperture extending therethrough, said wall having outer and inner surface regions adjacent said aperture, said plug assembly for sealing said aperture including inner and outer rigid compression plates and a plug body between said plates, said plug body including an outer resilient member adjacent the outer rigid compression plate and an inner resilient member adjacent the inner rigid compression plate and a separating member located between said outer and inner resilient members, said resilient members being movable radially in a direction substantially perpendicular to the spacing between the inner and outer rigid compression plates when the inner and outer rigid compression plates re moved toward each other, said separating member including opposed surface means frictionally engaging confronting surfaces of the outer and inner pair of resilient members for impeding radially expansion of the outer and inner resilient members in the region of the separating member when said outer and inner compression plates are moved toward each other, and means for moving said inner and outer compression plates toward each other for causing maximum radial expansion of the outer and inner resilient members in regions spaced from the confronting surfaces, said outer rigid compression plate having a peripheral surface overlying side surfaces of the outer resilient member, said plug assembly being located within the aperture with the peripheral surface of the outer rigid compression plate in engagement with the outer surface region of the container wall and with said outer and inner resilient members partially overlying the outer and inner surface regions, respectively, after said plug assembly has been actuated to seal said aperture.
Claim 10
Dependent Claim
