发明名称 Plastic containers and covers
摘要 An improved plastic container and cover with three connections for sealing the cover to the container. The top end of the container has an annular flange on the inner side of its sidewall forming a slot. The cover has two walls extending downward from its outer lip. The walls mate with the slot and the inner portion of the flange so as to form a straight-sided capped container. Slots may be provided in the outer edge of the cover to allow the cover to be pried off the container.
