ABSTRACT:
A spill-resistant container of deformable polymeric material is disclosed. The container includes a lid mountable in the container. A characterizing feature of the device resides in the provision of portions of the container surrounding the lid being inwardly deflectible into overlapping relation of the lid responsive to lateral, inwardly directed forces applied thereagainst. The invention includes a method of forming the container which involves applying a heat-sealable, heat-shrinkable membrane to portions of the container outwardly of the lid and thereafter causing the membrane to shrink, thus to deflect portions of the container into upwardly lapping relation of portions of the lid.
