Claims (15)

A laminated structure for producing a deformable article container comprising an aluminum foil, a film of an ethylene copolymer having a side chain carboxylic acid or ester group in a molecule, and at least one molecular layer of a chromium chromium complex salt primer therebetween. The copolymer of claim 1 wherein the copolymer is poly (ethylene / acrylic acid), poly (ethylene / methacrylic acid), poly (ethylene / methylacrylate), poly (ethylene / methyl methacrylate), poly (ethylene / vinyl acetate) And ionomers. The structure of claim 1 further comprising a film of synthetic resin in addition to the side of the foil opposite the side to which the primer layer is applied. At least one side of the aluminum foil substrate is coated with at least one molecular layer of polyacrylic acid chromium complex primer in the form of an alcoholic aqueous solution, and the coated substrate is heated to form an ethylene copolymer (side chain carboxylic acid or ester group in the molecule). And extrusion-coating the film, and cooling the laminated sheet, the method for producing a laminated structure for producing a deteriorated article container. The process of claim 4 wherein the copolymer is selected from poly (ethylene / acrylic acid) and ionomer resins. The method of claim 5 wherein the copolymer is poly (ethylene / acrylic acid) and the copolymer is withdrawn from the extrusion die at a melting temperature of about 550-600 ° F. 7. The method of claim 6, wherein the melting temperature is about 575 to 590 ° F. 9. Consisting of an aluminum foil having a copolymer film placed on the side where the contents of the container contact, a film of ethylene copolymer having side chain carboxylic acid or ester groups, and at least one molecular layer of chromium acrylate complex primer between them Container for deteriorated article made of a laminated structure for producing a deformable article container, characterized in that. Consisting of an aluminum foil having a copolymer film placed on the side where the contents of the container contact, a film of ethylene copolymer having side chain carboxylic acid or ester groups, and at least one molecular layer of chromium acrylate complex primer between them A package comprising a deteriorated content consisting of a deformable article container made of a laminated structure for producing a deformable article container. 10. The package of Claim 9, wherein the content is a toothpaste containing fluoride tooth decay inhibitor. The container of claim 10, wherein the laminate structure is formed in a tubular shape and further comprises a head portion firmly attached to one end of the tubular structure. 12. The container of claim 11, wherein the head is made of high density polyethylene. At least one molecular layer of chromium chromium acrylate complex primer in the form of an alcoholic aqueous solution is coated on at least one side of the aluminum foil substrate, and the coated substrate is heated to almost dry the primer, and at least one primer coated ethylene copolymer ( Extrusion coating the film of the side chain containing a carboxylic acid or ester group in the molecule, and cooling the laminate to prepare a laminate structure, which is then formed into the form of a container in which the polymer film is located on the inner surface of the container. Method for producing a container for an article. 14. The method of claim 13, further comprising forming the laminate structure in the form of a tube, and joining the head to one end of the formed tubular structure and having a melting temperature of about 575 to 590 ° F. 15. The method of claim 14, wherein the head is made of high density polyethylene. ※ Note: The disclosure is based on the initial application.
