  The present invention relates to a lid that closes a container that contains food or the like, and more particularly, to a lid that closes a container in a sealed state so as to prevent leakage of the juice or the like contained in the container.

  Conventionally, as a container and a lid of this type, a synthetic resin sheet obtained by vacuum forming is often used. The lid of this container needs to be properly locked to the opening of the container so that when the food is stored in the container and the opening of the container is closed, the juice of the contents in the container does not leak out. There is. For this reason, the lid is locked to the container with a predetermined force when the container on which the fitting portion is formed is put on the container so as to be fitted to the opening end of the container. . A flat tab is formed on a part of the outer edge of the lid so that the lid can be easily removed against a predetermined force.

  The “container with a lid and its molding method” disclosed in Patent Document 1 includes a container body made of a foamed resin sheet in which a hollow portion is formed over the entire circumference in the vicinity of the mouth of the container inner surface. A resin-molded lid formed with an annular projecting portion that is elastically fitted to the hollow portion is internally fitted. Thus, the space between the inside and outside of the container can be completely blocked by the fitting between the overhanging portion and the recessed portion. And when the pressure, vibration, etc. of the vapor | steam generate | occur | produced by microwave oven heating are added, a lid | cover will remove | deviate and the juice in a container will not leak.

  In the “food fitting container” disclosed in Patent Document 2, at least a pair of fitting recesses facing the center in the opening surface of the main body is formed on the outer peripheral edge of the upper end of the container body, and the engagement with the fitting recesses In this way, a pair of protrusions are formed on the inner surface of the back surface of the lid body, and further, a slit opening is formed on the side surface of the lid body so that a fingertip can be inserted. With such a configuration, it is said that the lid can be easily detached with one hand without providing flange means protruding on the side surface of the main body, and has excellent sealing properties.

  The “container lid” disclosed in Patent Document 3 is a lid composed of a top plate portion and an outer peripheral portion that covers an openable container so that the container can be opened and closed. A tab that bulges outward is formed on the outer peripheral portion of the lid. The tab is formed of a front bulge portion and a rear bulge portion, and the front bulge portion and the rear bulge portion are connected by a bendable connecting portion. When the lid of this container covers a part or all of the lidded container using a heat shrink film, it can be handled without being bulky despite having an expansion tab. .
