CLOSURE LID FOR OPEN MOUTH CONTAINERS

摘要

A closure lid for a container having an opening is provided to be directly sealed to the wall of the container as the lid is easily inserted into or removed from the container. A closure lid is combined with the inner surface of a container wall in a direction of the periphery to seal up the container. The lid is composed of a lower sealing panel(18) and an upper control panel(20). The lower panel has a sealing unit continued in a direction of the periphery with facing upward. The upper panel is protruded upward and provided with a peripheral pressure edge formed in the sealing unit or the same space of the sealing unit. The pressure edge of the upper panel is selectively moved upward and joined with the sealing unit to move the sealing unit to the outer side so that the sealing unit is sealed together with the container wall. The convex upper panel is bent downward for the lower panel between an upper position where the pressure edge and the sealing unit are combined minimally, and a curved lower sealing position. The pressure edge moves outward to seal and join the sealing unit with the container wall by moving the sealing unit outward and releases the upper panel at the sealing position.
