Abstract
Abstract A collapsible container primarily useful as a wastebasket can be constructed utilizing a flexible, tubular vertically oriented peripheral wall reinforced by vertically extending stiffeners and a rigid bottom fitting within the peripheral wall in order to hold it in a normal open configuration. The bottom wall is capable of being positioned in and of being removed from the peripheral wall. In the absence of the bottom wall in the peripheral wall the peripheral wall may be collapsed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
278 words
A collapsible structure having a vertically oriented peripheral wall and a bottom wall closing off the interior of the bottom of said peripheral wall the improvement which comprises: said peripheral wall being an endless wall formed of a flexible material which is sufficiently flexible so that said peripheral wall can be manipulated between a normal configuration in which the interior is opened up to as great an extent as possible and a collapsed, substantially flat configuration in which the interior of said peripheral wall is closed off, a plurality of vertically extending closely spaced, substantially parallel stiffeners located adjacent to one another on the exterior of said peripheral wall and attached to said peripheral wall, said stiffeners being spaced from one another only to a sufficient extent so as to permit said peripheral wall to be deformed from said normal to said collapsed configuration, and a plurality of supports located on the interior of said peripheral wall adjacent to the bottom thereof, said supports being spaced from one another so as to be capable of holding said bottom wall so that it is horizontally oriented and so as to be incapable of interfering with the manipulation of said peripheral wall between said normal and said collapsed configurations when said bottom wall is not located on said supports, said bottom wall fitting against said supports within said peripheral wall when in a normal position so as to reinforce said peripheral wall against being manipulated from a normal to a collapsed configuration, said bottom wall being capable of being removed from said supports so as to permit said peripheral wall to be manipulated from said normal to said collapsed configuration.
Claim 2
Dependent Claim
278 words
A collapsible structure having a vertically oriented peripheral wall and a bottom wall closing off the interior of the bottom of said peripheral wall the improvement which comprises: said peripheral wall being an endless wall formed of a flexible material which is sufficiently flexible so that said peripheral wall can be manipulated between a normal configuration in which the interior is opened up to as great an extent as possible and a collapsed, substantially flat configuration in which the interior of said peripheral wall is closed off, a plurality of vertically extending closely spaced, substantially parallel stiffeners located adjacent to one another on the exterior of said peripheral wall and attached to said peripheral wall, said stiffeners being spaced from one another only to a sufficient extent so as to permit said peripheral wall to be deformed from said normal to said collapsed configuration, and a plurality of supports located on the interior of said peripheral wall adjacent to the bottom thereof, said supports being spaced from one another so as to be capable of holding said bottom wall so that it is horizontally oriented and so as to be incapable of interfering with the manipulation of said peripheral wall between said normal and said collapsed configurations when said bottom wall is not located on said supports, said bottom wall fitting against said supports within said peripheral wall when in a normal position so as to reinforce said peripheral wall against being manipulated from a normal to a collapsed configuration, said bottom wall being capable of being removed from said supports so as to permit said peripheral wall to be manipulated from said normal to said collapsed configuration.
Claim 3
Dependent Claim
34 words
A collapsible structure as claimed in claim 1 wherein: said structure is a container, said peripheral wall is capable of being manipulated so as to be cylindrical when it is in a normal configuration.
Claim 4
Dependent Claim
41 words
A collapsible container as claimed in claim 2 wherein: said stiffeners have a uniform cross sectional configuration throughout their lengths and extend from the top to the bottom of said collapsible container when said peripheral wall is in said normal configuration.
Claim 5
Dependent Claim
44 words
A collapsible container as claimed in claim 1 wherein: said stiffeners are shaped so as to overlay the spaces between said stiffeners along said peripheral wall so as to hide said peripheral wall from view when said peripheral wall is in said normal configuration.
Claim 6
Dependent Claim
36 words
A collapsible container as claimed in claim 3 wherein: said peripheral wall is of a resilient character and said bottom wall fits within said peripheral wall so as to be resiliently engaged with said peripheral wall.
Claim 7
Dependent Claim
35 words
A collapsible container as claimed in claim 2 including: a band of decorative strips corresponding to said stiffeners located adjacent the top of said peripheral wall and extending around the interior of said peripheral wall.
Claim 8
Dependent Claim
93 words
A collapsible structure as claimed in claim 1 wherein: said structure is a container, said peripheral wall is capable of being manipulated so as to be cylindrical when it is in a normal configuration, said stiffeners have a uniform cross sectional configuration throughout their lengths and extend from the top to the bottom of said collapsible container when said peripheral wall is in said normal configuration, said peripheral wall is of a resilient character and said bottom wall fits within said peripheral wall so as to be resiliently engaged with said peripheral wall.
Claim 9
Dependent Claim
44 words
A collapsible container as claimed in claim 7 wherein: said stiffeners are shaped so as to overlay the spaces between said stiffeners along said peripheral wall so as to hide said peripheral wall from view when said peripheral wall is in said normal configuration.

Claim 11
Dependent Claim
70 words
A collapsible container as claimed in claim 7 wherein: said stiffeners are shaped so as to overlay the spaces between said stiffeners along said peripheral wall so as to hide said peripheral wall from view when said peripheral wall is in said normal configuration, a band of decorative strips corresponding to said stiffeners located adjacent the top of said peripheral wall and extending around the interior of said peripheral wall.
Claim 12
Dependent Claim
