ための内面テープである。 The easy-to-open metal lid 1 (hereinafter referred to as the metal lid) shown in FIGS. 1 and 2 has a teardrop opening on the panel portion 2 that serves as a spout for pouring out the liquid content 3, a drinking spout, or a slot for inserting a straw. A shaped opening 4 is formed, and a piece of tape 5 is releasably adhered to the outer surface of the panel portion 2 so as to cover the opening 4. Note that 5x is tape piece 5
This is the glued part, and 5y is the knob.
The adhesion is performed by thermal adhesion (thermal adhesion of a thermoplastic film forming the inner surface layer of the tape piece 5 or adhesion using a hot melt adhesive), adhesive, or the like. Reference numeral 6 denotes an inner surface tape for protecting the end surface 4a of the opening 4 where the metal is exposed by blocking it from the liquid content 3.

る。 Next, a specific example will be explained with reference to FIG. 3, which is an enlarged view of the vicinity of the opening 4. The panel part 2 is made of a metal plate such as a tin-plated steel plate or stain-free steel, and the inner surface is coated with a protective coating 7, and the outer surface is also coated with a primer layer as required.
It is covered with a baked paint film, a printed film, etc. (not shown). The tape piece 5 is composed of, from the inner side, an adhesive layer 5a, a plastic film layer 5b (for example, made of polyethylene terephthalate), a vapor-deposited aluminum layer 5c, and a coating film 5d.

されて、開口が行なわれる。 The inner surface tape 6 has a plastic film layer 6a.
(made of polyethylene, for example) and an adhesive layer 6b, and is adhered (adhesive) to the inner surface 2a of the panel section 2 around the opening 4, and the opening 4
It is recessed inward and is adhered (adhesive) to almost the entire surface of the tape piece 5 above the opening 4 except for the peripheral edge. The end surface 4a is covered with the inner surface tape 6 and the tape piece 5, leaving a slight gap 8 (exaggeratedly drawn in FIG. 3, but actually very small). , even when the gap 8 remains like this, it is called covered).
When opening the opening, when the knob 5y is pulled up, the inner peripheral edge of the opening 4 of the inner surface tape 6 is torn, and the inner surface tape portion within the opening 4 is removed together with the tape piece 5, thereby completing the opening.

る。 However, in the past, these adhesives were bonded in air, so air, that is, oxygen and moisture, remained in the gap 8. Therefore, when the panel part 2 is made of a metal plate based on steel, the edge surface The exposed steel of 4a is generated during long-term storage (for example, one year) of the container 9 (that is, filled with the liquid content 3 and sealed with the metal lid 1 forming a double seam 10). When the tape is opened, reddish-brown rust adheres to the tape piece 5 and the inner tape 6, and the end surface 4a becomes rust-colored, resulting in problems such as lowering the product value.

方法を提供するものである。 In order to achieve the above object, the present invention includes an opening formed in a panel part, a piece of tape removably adhered to the outer surface of the panel part covering the opening, and a tape piece around the opening part of the panel part. In the method for producing an easy-to-open metal lid in which a plastic film is adhered to the inner surface of the opening, and the end face of the opening is covered with the tape piece and/or the plastic film, the tape covers the end face. The present invention provides a method for manufacturing an easy-to-open metal lid, characterized in that the adhesive piece or the plastic film is bonded in a nitrogen gas atmosphere.
以下本発明について説明する。 The present invention will be explained below.

It is heat-sealed so as to cover 4a. Further, the tape piece 25 has an inner layer 25a made of a plastic film (for example, made of nylon 12), an intermediate layer 25b made of a vapor-deposited aluminum layer, and an outer layer 25c made of a paint film.
is heat-sealed to the outer surface of the panel portion 22 and the outer portion 26a of the plastic film 26. Note that 27 is a primer layer (for example, made of phenol-epoxy paint).
この場合は、プラスチツクフイルム２６は概ね

なる。 In this case, the plastic film 26 can cover the end surface 24a without leaving any gaps, but in some places there may be slight gaps 28 due to wrinkles.
occurs. Therefore, in this case as well, by bonding the plastic film 26 in a nitrogen gas atmosphere, the gap 28 is filled with nitrogen gas, making it difficult for the end surface 24a in the gap 28 to rust.

３４ａが発錆し難くなる。 FIG. 6 shows the vicinity of the opening 34 of the metal lid, where the tape piece 35 is recessed and adhered to the inner surface tape 36 within the opening 34 of the panel section 32, and is not shown. However, the layer configurations of the tape piece 35 and the inner surface tape 36 are similar to those of the tape piece 5 and the inner surface tape 6 shown in FIG. 3, respectively.
Also in this case, by adhering the tape pieces 35 in a nitrogen gas atmosphere, the gap 38 is filled with nitrogen gas, so that the end face 34a in the gap 38 is less likely to rust.
