A container and lid of molded plastic material having a fastener structure integral with the container and lid to connect the lid onto the container. The fastener comprises two complementary series of element, one projecting axially upwardly on the wall of the container, the other downwardly on the rim of the lid, interengage when the cover is pressed down. The elements having head portions wider than the base portions, so that when interengaged, they may not be separated without stressing or distorting the material.

A container and lid of molded plastic material having a fastener structure integral with said container and lid to connect said lid onto said container, in which said lid has a peripheral channel facing the top edge of the wall of said container with the top edge of said wall in said channel, two peripheral series of similar complementary elements integral with the top edge of said wall and in said channel, each element being wider at its extremity in the peripheral direction than at its base adjacent its supporting member, so that the spaces between the elements are wider adjacent each of said members and are complementary to the elements, so that the interdigitated elements interlock against separation, the material of the members being sufficiently pliable for insertion and removal of at least one element from one series into space between elements of the other series when all remaining elements are interengaged, said elements of said two series having laterally inclined interengaging surfaces which act to apply force between said members radially of said container, said container and lid having continuous peripheral abutting surfaces and said laterally inclined surfaces on said elements applying force between said lid and container to press said abutting surfaces together tightly and seal said container.
