Title:
FLEXIBLE TUBE SHEET, AND METHOD FOR MANUFACTURING A TUBE BODY
Document Type and Number:
WIPO Patent Application WO/2010/107270
Kind Code:
A3
Abstract:
The present invention relates to a flexible tube sheet constituted by aluminum foil and plastic materials and used as a tubular container for containing cosmetics, medicine, toothpaste or the like, and also relates to a method for manufacturing a tube body. The flexible tube sheet of the present invention comprises: an inner thermally bonded layer forming an inner surface of a tube and an outer thermally bonded layer forming an outer surface of the tube; a gas cutoff layer for preventing the penetration of gas through the tube; and a bonding layer for bonding the inner and outer thermally bonded layers and the gas cutoff layer, wherein said gas cutoff layer is constituted by aluminum foil and a reinforcement layer formed by laminating plastic films onto both sides of the aluminum foil. The tube body of the present invention, formed by bonding the laminate sheet into a circle, prevents the deformation of the roundness thereof caused by variations in the outside temperature, thereby suppressing defects in products caused by the production environment, and specifically, differences in temperature.
