Abstract

Abstract A food carrying and display system includes a plurality of containers having one top and supportable in vertical array by stacking means including a coaxially disposed adjustable-length elongate screw provision; each container has a rim and a central spacer protecting the rim from distortion, both of which optionally may be detachable for cleaning and for ease in manufacturing, by use of an extra spacer and a single elongate screw and the top as few as one container can be carried with the top protectively in place sealing it closed; special carrying and handling provisions include a ring nut at the top of the assembly and around each container at mid-height a safety flange.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 237 words
In an array formed of a plurality of containers held in vertically spaced relation by stacking means coaxial therewith and adjustable with respect thereto and a top for the uppermost container, the improvement comprising: a rim around each container; the stacking means including: said top and each container having a hole centrally therethrough, a spacer on each container around the hole, coupling means passing through each said spacer and hole, each rim comprising a circular member on the container and safety pickup means on each container comprising a planar flange on the circular member radially protrusive from an intermediate portion thereof, a first cleaning provision comprising means detachably holding each rim, the means detachably holding including an upstanding flange fixed around the perimeter of each container and having protrusion for fitting said rim and further including means locking the rim to the upstanding flange, a second cleaning provision comprising means detachably holding each spacer, the means detachably holding each spacer comprising a tubular core fixed as part of each container, each spacer and tubular core having mutually engaging convolutions, the coupling means comprising means for sealing the rims of said containers and top including means for compressing together the rims of said containers and top, and means for preventing distortion of the containers on said compressing together, comprising said spacers having height proportioned for limiting said compression of the rims by sharing the load of said compression.
Claim 2
Dependent Claim 237 words
In an array formed of a plurality of containers held in vertically spaced relation by stacking means coaxial therewith and adjustable with respect thereto and a top for the uppermost container, the improvement comprising: a rim around each container; the stacking means including: said top and each container having a hole centrally therethrough, a spacer on each container around the hole, coupling means passing through each said spacer and hole, each rim comprising a circular member on the container and safety pickup means on each container comprising a planar flange on the circular member radially protrusive from an intermediate portion thereof, a first cleaning provision comprising means detachably holding each rim, the means detachably holding including an upstanding flange fixed around the perimeter of each container and having protrusion for fitting said rim and further including means locking the rim to the upstanding flange, a second cleaning provision comprising means detachably holding each spacer, the means detachably holding each spacer comprising a tubular core fixed as part of each container, each spacer and tubular core having mutually engaging convolutions, the coupling means comprising means for sealing the rims of said containers and top including means for compressing together the rims of said containers and top, and means for preventing distortion of the containers on said compressing together, comprising said spacers having height proportioned for limiting said compression of the rims by sharing the load of said compression.
