Conventionally, a ring having a planar shape as shown in Fig. 4 has been used along the inner edge of the container flange as one of devices for obtaining a package for retort food, etc., which is made by sealing a plastic container with a flange and a lid. A device for heat sealing with a heating plate 1 is employed. However, in the case of retort food packaging, the seal strength from the inside of the container A is legally required to be 2.3 kg/15 cm width, so if the planar shape 2 as shown in Figure 4 is used, the seal strength can be high, but when opened from the outside. There was a problem in that the lid material broke and was not easy to open.

As a result of various studies to solve these problems, we developed a ring-shaped heat-sealed package that improves the sealing performance from the inside and is easier to open from the outside by heat-sealing the container with the flange and the lid material in a ring shape. They came up with the idea of the shape of the board.

This invention consists of a container A having a flange portion and a lid material B.
In a ring-shaped heat sealing device, the ring part has a flat part 3 along the inner edge of the flange part, and the outside of the flat part has a shape that is less susceptible to pressure than the tapered part 4. The present invention relates to a sealing device.

Polypropylene having a flange portion 5 as in 1;
Saponified polypropylene/ethylene vinyl acetate copolymer/polypropylene, polypropylene/pynylidene chloride/polypropylene, etc. Plastic container A with PET/Al/sealing material layer, polypropylene/vinylidene chloride/sealing material layer, polypropylene/ethylene vinyl acetate copolymer Lid material B such as saponified material/sealant layer etc.
In order to obtain a package that is heat-sealed and has a peel strength of 2.3 kg/15 cm width or more from the contents side and is easy to open from the outside as shown in FIG. Flat part 3 with a width of 1.0 to 3 mm
By using the sealing device 1, which has a ring shape with a depth of 6 and a tapered part 4 of 0.3 to 3.0 mm, which is less susceptible to pressure than the flat part 3, and a ring shape of 0.1 to 1.0 mm, it is easy to prepare the intended retort packaging. It becomes possible to obtain Here, the depth 6 of the ring shape, the width of the flat part 3, the shape of the tapered part 4, etc. can be changed depending on the materials of the container A and the lid material B. Here, in the case of the ring shape 1 which does not have a flat part as shown in Fig. 5, the entire pressure is applied to the ring tip 7, so the sealing material layer of the lid material A is easily cut, and the sealing strength from the contents side is extremely poor. Become.
