Claims

[Claims for Utility Model Registration] (1) A container comprising an outer material, an intermediate material, and an inner material laminated and sealed to the opening edge of the container in a peripheral sealing area to close the opening end of the container. In the lid, the outer surface material has a contour capable of covering the entire surface of the opening edge of the container, and the inner surface material constitutes an annular body extending over the sealing area, and the inner peripheral edge is closer to the inner peripheral edge of the sealing area. is located near the center of the open end and is sealed to the back surface of the outer material by a tight seal part, and can be sealed to the open end of the container by an easy-to-open seal part in the seal area, and the intermediate The material is sandwiched between the inner surface material and the outer surface material with the outer peripheral edge located within the sealing area, and the outer surface of the inner surface material or the inner surface of the outer surface material is not sealed. Easy-to-open container lid. (2) The intermediate material covers the entire surface of the opening end closer to the center than the sealing area of the outer surface material, and is not sealed to the inner surface material. Openable container lid. (3) The easy-open container lid according to claim 1, wherein the intermediate member has an annular shape, and an inner peripheral edge thereof is located closer to the center of the opening end than an inner peripheral edge of the sealing area.
