Abstract
A single-piece, molded plastic closure is disclosed and is constructed and arranged for assembly into a container lid opening. The closure includes an annular side wall having a lid engaging portion and an end panel. The end panel is configured with an annular recessed section and an annular frustoconical section which surrounds the annular recessed section. When a vacuum is applied to the surface of the lid for movement of the container the lid may bow and affect the degree of engagement between the closure and the lid opening. The addition of the end panel offsets the effect of the vacuum and enhances the degree of engagement between the closure and the opening so as to prevent dislodgement of the closure during vacuum head movement of the container.
