Description

【発明の詳細な説明】 (産業上の利用分野) 本発明は、シュリンク包装用フィルムを用いたピロー
包装のトップシーラーに関するものである。
TECHNICAL FIELD The present invention relates to a top sealer for pillow packaging using a shrink packaging film.

(Prior Art) A pillow packaging method using a shrink packaging film is disclosed in Japanese Patent Application No. 1-2390 by the same applicant as the application.
Although disclosed in Japanese Patent No. 66 and Japanese Patent Application No. 1-317830, the purpose thereof is to provide a packaging method having an appearance similar to that of stretch packaging and having a high freshness retaining function.

(Problems to be solved by the invention) In the conventional top sealer for pillow packaging, the film is sandwiched between steel materials, but the film for shrink packaging is
It was apt to be deformed by heat, and pressure unevenness sometimes occurred on the sealing surface.

Also, the shape of the sealing surface is as shown in FIGS.
Although there are side seals, goose seals, and flat seals, a side seal that cuts off multiple layers of outside air is the most suitable in order to improve airtightness, but when a side seal is made using a shrink wrapping film, a steel material is used. When sandwiched between the sealers of each other, the mountain angles of the steel material of the side grain hit the film at right angles to the direction in which the film shrinks, and the film was melted, and it was unavoidable to use a mat seal or a flat seal.

In view of the above conventional drawbacks, it is an object of the present invention to provide a top sealer having a small seal pressure unevenness and a high sealing degree in a pillow package using a shrink wrapping film.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a sealing material of a sealer on the center seal side, which is made of an elastic material such as silicone rubber, among sealers that face each other with a sealed object. It is characterized in that the sealer on the other side is made of steel, and a compression spring and an air cylinder are provided on the steel sealer.

(Function) In the sealer configured as described above, since the elastic property such as silicon rubber is provided on the seal surface of the sealer on the center seal side and the sealer on the other side is made of steel, the film on the steel sealer side is Sealed in a flat state, heat transfer from the steel sealer can be evenly applied to the adhesive surface.

Moreover, since the steel sealer is provided with the compression spring and the air cylinder, momentary forced pressurization can be performed, pressure unevenness is reduced, and sealing is completed before the shrink film is fused.

On the contrary, if the center seal side is made of a steel sealer, the wall thickness of the center seal portion obstructs the passage of heat, which easily causes a sealing failure, and when the sealing takes time, the film is fused.

(実施例) 以下、図面に示す実施例により、本発明を詳細に説明
