Abstract
Abstract A refreezable container for a cold storage structure which can be releasably secured to the lid of the structure is the subject of the present invention. The container comprises yieldable spaced apart sidewalls which form an enclosure for holding a refreezable liquid. A passageway through the enclosure and its sidewalls receives an elongated stud. The stud has a gripping surface at one end and is threaded on the other end. Along the length of the stud a lateral projection extends outwardly so that the combined dimension of the projection and the stud is greater than the corresponding dimension of the passageway. The yieldable passageway walls permit insertion of the stud which may then be turned to screw the threaded stud into a correspondingly threaded receptacle in the lid of the cold storage structure.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
179 words
Structure for presenting a cold storage area, said structure comprising: an open top body portion defining said area; a lid portion adapted to be received by said body portion to close said open top, said lid presenting an open cavity on the side of the lid facing said area, means for presenting an enclosure having spaced apart flexible sidewalls and adapted to receive a freezable liquid, said enclosure presenting means being adapted to be received in said cavity, means for defining a passageway through said sidewalls and a portion of said enclosure; a locking member received in said passageway; and means on said locking member for cooperating with the passageway defining means to prevent removal of said locking member from said passageway; means on said lid portion for cooperating with said locking member to releasably lock said enclosure presenting means to said lid portion, said locking member being accessible upon opening of said lid whereby a user of said structure may operate said member to release said enclosure presenting means for insertion of the latter into a freezer compartment.
Claim 2
Dependent Claim
179 words
Structure for presenting a cold storage area, said structure comprising: an open top body portion defining said area; a lid portion adapted to be received by said body portion to close said open top, said lid presenting an open cavity on the side of the lid facing said area, means for presenting an enclosure having spaced apart flexible sidewalls and adapted to receive a freezable liquid, said enclosure presenting means being adapted to be received in said cavity, means for defining a passageway through said sidewalls and a portion of said enclosure; a locking member received in said passageway; and means on said locking member for cooperating with the passageway defining means to prevent removal of said locking member from said passageway; means on said lid portion for cooperating with said locking member to releasably lock said enclosure presenting means to said lid portion, said locking member being accessible upon opening of said lid whereby a user of said structure may operate said member to release said enclosure presenting means for insertion of the latter into a freezer compartment.
Claim 3
Dependent Claim
39 words
The invention of claim 1, wherein said passageway defining means comprises a first recessed section in one of said sidewalls; a second recessed section in the other of said sidewalls and a tubular section extending between said recessed sections.
Claim 4
Dependent Claim
81 words
The invention of claim 1, wherein said locking means comprises an elongated stud having an enlarged head presenting a gripping surface and said means on the locking member comprises a projection extending laterally from it; said tubular section having a cross-sectional dimension larger than the corresponding dimension of said stud and smaller than the corresponding dimension of the stud plus the lateral projection, said tubular section being yieldable to an extent to permit insertion of the stud and the lateral projection.
Claim 5
Dependent Claim
39 words
