Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a package consisting of a deep-drawn container and a lid.

(b) Prior art As a sealing method for a package c consisting of a deep-drawn container a and a lid b as shown in Figs. As described in ``Packaging Industry'' and shown in Figures 4 and 5, a seal part d where a container a and a lid b are sealed in a ring shape is formed in order to open the lid b. There are dot stickers f, solid stickers g, date stickers h, etc. as stickers for the tag part e.

However, in these methods of sealing the tag part e, as shown in FIG. When heating and sterilizing the container in a tank to improve its shelf life, there was a problem in that the heat caused the lid and the seal to adhere to each other, making it difficult to open the lid B from the container A.

(c) Problems to be solved by the invention The problem to be solved by the invention is to improve the sealing method between the container and the lid in a package to make the lid easier to open.

(d) Means for solving the problem The present invention provides a package consisting of a container having an edge and a lid tightly sealed around the container at the edge. A tag part is formed that protrudes outward from a sealing position between the container and the lid, a convex part is formed on the tag part that projects toward the lid at a position away from the sealing position, and the lid and the container are connected together. The container is configured such that a gap is formed between the lid and the container when the lid and the container are tightly sealed at the sealing position.

(e) Operation In the package having the above structure, packaging is completed by filling the container with the contents and then sealing the lid in an annular shape around the edge of the container.

After packaging is completed, the contents are heated and sterilized, but due to the heat at that time, the unsealed part is not adhered due to the convex part, and when the package is opened, the convex part formed on the edge of the container You can easily open the lid by pinching the floating edge of the lid and pulling up.

(F) Embodiments Examples of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a package according to the present invention, which includes a container 2, a lid 3, and an annular seal portion 4.

The container 2 is deep-drawn from resin or the like, and has an annular rim 21 around its upper part, and this rim has a further outwardly projecting part 22 (referred to as a tag part) 22 formed therein.

The tag part is formed by pressing the upper mold 6 against the lower mold 5 when molding the container 2 using a mold as shown in FIG. A convex portion 23 protruding from the upper surface of the edge portion is formed by the forming pin 7 . 8 is a compressed air inlet.

The lid 3 has a flat plate shape and has an outer shape that is almost the same as the upper surface of the container 2. The lid 3 has a lip portion 31 corresponding to the lip portion 21 of the container, and a tag portion 3 corresponding to the tag portion 22 of the container.
It is equipped with 2.

The annular seal portion 4 is heat-sealed in an annular shape by placing the lid 3 on the container 2 and using a sealing device (not shown). At this time, the tag portion 32 of the lid 3 is in a state of floating above the tag portion 22 of the container (FIG. 2) because of the convex portion 23 of the container (located outside the annular seal portion 4).

The package 1 having the above structure is placed in a heat sterilization tank (not shown) and heat sterilized, but the heat at this time causes the edge 31 of the lid to come into close contact with the edge of the container. However, since the tag part 32 of the lid is a convex part 23 of the container, it remains floating above the tag part 22 of the container, and when opening the container, the lid 3 can be easily opened by pinching and pulling up the tag part 32. can.

(g) Effects In the package according to the present invention, by forming a convex portion on the edge of the container, a gap is created between the tag portion of the container and the tag portion of the lid, making it easier to open the lid. There is an effect.
