Abstract:
1. A stackable container assembly, comprising: a main body; an upstanding rim portion having an upper surface; and a flexible bottom portion, said flexible bottom portion having a lower surface comprising at least one support surface for supporting said container assembly on a horizontal surface, said lower surface further comprising at least one projection that is disposed radially inwardly from said support surface, and wherein said flexible bottom portion is configured so that said projection will flex downwardly into a position that is adjacent to an upstanding rim portion of an underlying container assembly when said container assembly is stacked on top of another container assembly; wherein said container assembly comprises a removable lid portion, and wherein said upstanding rim portion is located on said removable lid portion; and wherein said removable lid portion comprises a flexible diaphragm that is constructed and arranged to accommodate relative pressure changes between an interior of said container assembly and ambient conditions by flexing, whereby flexure of the rest of the container assembly as a result of such relative pressure changes is minimized.
