等がある。2. Description of the Related Art Conventionally, a tube container has been used as a container for taking out a fixed amount of contents from a viscous substance such as a paste toothpaste. As such a tube container, for example, a laminated tube container that uses a body part in which both ends are adhered by winding a laminated film, an extruded tube container that uses a cylindrical body made by extruding a resin into a cylinder, or a mouth part and a tubular part. There is a blow tube container or the like for integrally molding the body part of

器の内容物に制限があった。Of the above-mentioned three types of tube containers, in the case of the extruded tube container and the blow tube container, the material used for the body is limited to resin. When a resin is used as a raw material, a laminate using a resin having the gas barrier property is used to protect the contents. Usually, a laminated body of this type is a multi-layered body having five or more layers, and it is difficult to extrude the laminated body at the same time to form a uniform diameter and thickness. Further, in order to obtain a laminate that can be extruded, there is a limitation in the selection of the resin, and it is difficult to obtain sufficient gas barrier properties and adhesive strength between resin layers. Therefore, the contents of these containers are limited. was there.

いる。On the other hand, in the laminated tube container, the film material can be freely selected according to the contents.
In particular, an aluminum foil having excellent gas barrier properties and moisture resistance can be used in the laminated film, so that the contents can be effectively protected. Further, since the laminated film firmly laminated with the adhesive is wound and used as the cylindrical body, the adhesive strength between the layers is also good. Therefore, the laminated tube container is generally widely used for various contents.
