本考案は、アルミ容器を成形加工するために用
いられる容器成形用シートに関する。[Detailed Description of the Invention] The present invention relates to a container forming sheet used for forming aluminum containers.
たとえば、アルミニウムは展性を有するからア
ルミニウム箔を材料とした包装容器が冷間成形法
で作られている。上記包装容器はアルミニウムの
具有する特性で防湿性、ガス遮断性に優れ、医薬

が、材料であるアルミニウム箔が薄いと、成形時
に割れが生じ易く、深絞り容器を作ることが難か
しく、またアルミニウム箔が厚いと容器としての
適当な剛性が得られず、しかもコスト高になつて
実用的ではない。 For example, since aluminum has malleability, packaging containers made of aluminum foil are made by cold forming. The above-mentioned packaging containers have excellent moisture-proofing and gas-barrier properties due to the properties of aluminum, and are suitable for enclosing pharmaceuticals and food products distributed at room temperature. However, if the aluminum foil used as the material is thin, cracks are likely to occur during molding. It is difficult to make deep-drawn containers, and if the aluminum foil is too thick, adequate rigidity for the container cannot be obtained, and the cost is high, making it impractical.

着剤とすると、深絞りすることができず、割れや
裂けが生じるという難点がある。 Therefore, an aluminum sheet was devised in which aluminum foil was joined with a stretched nylon film and an unstretched polyester film in the form of a sandwich, but with this aluminum sheet, the thickness of the aluminum foil could be made thinner, and the drawing depth could also be reduced per aluminum foil unit. However, external factors that occur in the stretched film during deep drawing, such as humidity and heat, can cause peeling between the aluminum foil and the stretched film, and in order to prevent such peeling, If the intervening adhesive is a hard adhesive with a large cohesive force, deep drawing cannot be performed, resulting in cracks and tears.
本考案は上記した点に鑑みてなされたもので、
未延伸フイルムと延伸フイルムの間にアルミニウ

を提供することを目的とする。 This idea was made in view of the above points,
A thermoadhesive resin film is bonded to the stretched film side surface of a laminate that has aluminum foil between an unstretched film and a stretched film, making it possible to form a deep-drawn container, and peeling between the stretched film and aluminum foil. It is an object of the present invention to provide a sheet for forming a container which prevents the occurrence of.
以下本考案の一実施例を図面につき説明する。 An embodiment of the present invention will be described below with reference to the drawings.
第１図において符号１は容器成形用シートであ
つて、その容器成形用シート１は、ナイロンまた

されている。 In FIG. 1, reference numeral 1 denotes a container-forming sheet, and the container-forming sheet 1 consists of an unstretched film 2 made of nylon or polypropylene with a thickness of about 60 μm, and a thick film 2 made of nylon or polypropylene with a thickness of about 60 μm. A thermoadhesive resin film 6 of polyvinyl chloride or polyethylene is pasted on the side where the stretched film 3 of a laminate 5 is formed by interposing an aluminum foil 4 of about 40 μm in thickness between stretched films 3 of about 20 μm in diameter. It is composed of a combination of

があり、延伸フイルムとアルミニウム箔の界面接
着強度の小さい接着剤を用いてもアルミニウム箔
と延伸フイルムの間で剥離が生じない。 When a drawn aluminum container is made using the container forming sheet 1, cold forming is carried out using normal male and female molds. It is arranged so that Therefore, since the stretched film, which has more elastic deformation, is located in the inner layer than the aluminum foil,
It is effective in assisting the stretching of aluminum foil during molding, and peeling does not occur between the aluminum foil and the stretched film even if an adhesive with low interfacial adhesion strength between the stretched film and the aluminum foil is used.
また延伸フイルムの内層に熱接着性樹脂フイル

ことによる熱封緘の困難性を解消し得ることにな
る。 Further, since the thermoadhesive resin film is provided as the inner layer of the stretched film, it is possible to solve the difficulty of heat sealing due to the high crystallinity of the stretched film.
以上述べたように本考案によれば、アルミニウ

る。 As described above, according to the present invention, since the stretched film and the thermoadhesive resin film are laminated on one side of the aluminum foil, the stretching of the aluminum foil during molding can be assisted by the stretched film. It is now possible to form the aluminum foil and the stretched film, and even if the adhesive between the aluminum foil and the stretched film is weak, peeling will not occur between them, and the difficulty of heat sealing the stretched film can be solved by using a thermoadhesive resin film. This has the effect that it can be resolved by
