ものである。[Detailed explanation of the invention] (a) Industrial application field This invention is mainly used for mushrooms such as fresh shiitake mushrooms, vegetables, etc.
Accommodates, transports, stores, and stores fresh foods such as fruits.
The present invention relates to a device used to spread a film-like cover over the opening of a container for sale or the like after the contents have been contained therein.
(b) 従来の技術

れていた。(b) Prior art Containers used for the above purposes are usually vacuum-formed or pressure-formed thin plates made of hard polyvinyl chloride, polystyrene, etc., and their covers are made of wrapped soft polyvinyl chloride, polychlorinated polyvinyl chloride, etc. Vinylidene, polyethylene, etc. are used, but conventionally, in order to cover the opening of a container with these films, the main methods have been to glue them with an adhesive or to heat-melt and heat-seal them. I was worried.

ガス等に接触することが必要であり、従つて完全
固着した覆蓋でなく塵埃等の侵入は完全に防止し
つゝ簡単に開閉し得る覆蓋が要望される処であつ
た。 However, adhesion poses a risk of dust adhesion during work, which is not only unclean, but also causes hygiene problems due to the use of solvents. Furthermore, according to the heat sealing method, not only complicated equipment for heating and pressurizing, etc. and heat consumption required for melting become large, but also, as mentioned above, raw shiitake mushrooms stored in this container,
In order to maintain the freshness of raw vegetables, it is necessary to allow them to come into contact with oxygen, carbon oxide gas, etc. through slight air circulation, rather than storing them in a completely sealed container. There was a need for a cover that could be easily opened and closed while completely preventing this.
(c) 考案が解決しようとする問題点

である。(c) Problems that the invention aims to solve This invention solves the above-mentioned drawbacks of conventional container covers, spreads a wrap-like film uniformly over the opening of the container, and prevents dust, insects, etc. The purpose of this work is to provide a cover spreading device that prevents intrusion and that allows the cover to be opened or removed easily during storage or consumption of the contents without tearing the cover open. I have completed this.
(d) 問題点を解決する為の手段
前記ような、従来法の欠点を解するためになさ

状態で覆蓋となることが必要である。 1 is a film heater for heating the membrane-like film that serves as the cover and spreading it on the opening of the container, and is equipped with a heating device such as electric heating using nichrome wire or the like, and heating is performed on the entire surface of the plate. Although the heating temperature varies depending on the material of the film used, the film softens and is spread over the opening 511 of the container 5, and when cooled, it shrinks and becomes a cover while retaining tension. is necessary.
2は装置本体であつて、真空成形又は圧空成形
により成形された、ポリ塩化ビニール樹脂、ポリ
スチレン樹脂等の硬質薄板製容器5を開口部51
の鍔状平坦部が水平となるように保持し、本体底
部には減圧用の吸気孔4があつて、真空装置に連
結し、容器外周、特に開口部の周縁を減圧にす
る。 Reference numeral 2 denotes the main body of the apparatus, in which a container 5 made of a hard thin plate made of polyvinyl chloride resin, polystyrene resin, etc., molded by vacuum forming or pressure forming is inserted into an opening 51.
The flange-shaped flat part of the container is held horizontally, and the bottom of the main body has an intake hole 4 for reducing pressure, which is connected to a vacuum device to reduce the pressure around the outer periphery of the container, especially around the opening.
更に容器開口部の周縁の余剰のフイルムをトリ
ミングする為の溶断用熱線3を配設した構造より
なるものである。 Furthermore, the structure includes a fusing hot wire 3 for trimming excess film around the periphery of the opening of the container.
即ち、フイルムヒーター1により予熱された覆
蓋用フイルム5は、予熱展着板1に付着したまゝ
で、装置本体2に把持され内容物を収容した容器
6の開口部51の鍔状平坦部に展着される。 That is, the covering film 5 preheated by the film heater 1 remains attached to the preheating spreading plate 1 and is gripped by the main body 2 of the apparatus and is applied to the brim-like flat part of the opening 51 of the container 6 containing the contents. It will be deployed.
次にフイルム外周の余剰部は通電により加熱さ
れた溶断用熱線3により溶断されこの際にフイル
ム外周部は冷却収縮して、容器の開口部51に捲
着して覆蓋を完全にする。 Next, the excess portion of the outer periphery of the film is cut by the hot wire 3 heated by electricity, and at this time, the outer periphery of the film is cooled and shrinks, and is wrapped around the opening 51 of the container to complete the lid.
更にフイルムヒーター1を元状に戻すことによ
つて、予熱軟化したフイルムは、フイルム自体の
冷却による収縮に基づく張力と、外部の減圧によ
る吸引力とにより、容器開口部に張着する。 Further, by returning the film heater 1 to its original state, the preheated and softened film is stuck to the opening of the container by the tension caused by the shrinkage of the film itself as it cools and by the suction force caused by the external reduced pressure.
又、上記の装置には、フイルムヒーターの移動
及びフイルム、容器の仕込み等は手動、動力駆動
何れも可であつて、ヒイルムヒーターに温度調節

ある。尚、予熱用の熱源は電熱に限定されるもの
ではない。 In addition, the above-mentioned device can be operated manually or powered for moving the film heater and loading the film and containers, and is equipped with a temperature control device in the film heater, a pressure reduction control device in the main body of the device, and a heating wire for fusing. It is effective to automate each process by providing an energization adjustment device. Note that the heat source for preheating is not limited to electric heat.
(e) 作用
