られている。2. Description of the Related Art Generally, when food and drink are placed in a container and put in a distribution process such as sales, in order to prevent mischief with food and drink in the container, it is necessary to reseal the container once opened. Pilfer proofing means are provided so that it cannot. For example, the heat sealing method is a typical method. The heat-sealing method is used for many food packages because it has the characteristic that it does not require a special structure of the container itself.

融着させる方法である。シールヘッドは平坦な面を有す
るブロックであって、容器に冠した蓋体に所定圧力で押
圧して接触するように構成されている。This heat-sealing method is, for example, a synthetic resin-made drop lid-shaped device that is dropped into the opening of a cup-shaped container that contains food and drink, and its peripheral edge is placed on the peripheral edge of the top surface of the container. In this method, the lid (inner lid) is capped on the container, and the seal head of the heat sealer fuses the peripheral edge of the lid and the peripheral edge of the top surface of the container. The seal head is a block having a flat surface, and is configured to press a lid capped on the container with a predetermined pressure to come into contact therewith.

ことはできないから、悪戯をすることはできないという
ものである。Therefore, since the lid is integrally connected to the container, the lid must be peeled off from the container when the food or drink is taken out. However, once the lid is peeled off from the container, the lid cannot be brought into close contact with the container again, so that no mischief can be made.

There are many. In this case, a specific shape is applied to the peripheral portion of the top surface of the container, or an annular flange portion having a predetermined width is formed on the peripheral portion of the top surface, and the flange portion is given the specific shape. In such a case, the film sheet and the lid must be heat-sealed without destroying the shape of the peripheral portion of the top surface.

ないで残るため、これらの周縁部がめくれて剥がれ易く
なるという問題がある。Therefore, for example, when a bead is formed on the peripheral portion of the top surface of the container, in the conventional heat sealer, the end face of the seal head is flat, and therefore the cross-sectional shape of the bead is formed. However, the fusion-bonded portion between the lid and the peripheral portion of the top surface of the container becomes linear rather than planar, and the fusion-bonded portion may be insufficient to completely seal the container. Further, since the peripheral edge portion of the lid body and the peripheral edge portion of the film sheet remain without being adhered, there is a problem that these peripheral edge portions are turned over and easily peeled off.

変えただけでは、前記問題の充分な解決とはならない。Therefore, in such a case, it has been attempted to increase the area of the peripheral portion of the lid or the like so as to wrap around the peripheral portion of the top surface of the container to prevent the curling up. The area of the part does not change, and when the container has a circular shape, wrinkles occur and the appearance is deteriorated. Therefore, changing the shape of the container or lid does not sufficiently solve the above problem.
