Claims

[Claims for Utility Model Registration] 1. A surface layer made of a polyolefin resin, an intermediate layer containing a gas barrier layer and a paper layer in a laminated structure, and a linear saturated polyester resin having a glass transition temperature of 40°C or higher. A blank board for a paper container for forming a paper container comprising a laminated sheet for a paper container comprising a back layer, and an inner peripheral surface layer of the container is comprised of the back layer of the laminated sheet. An opening for passing the pouring tool through the blank board is formed at a predetermined position, and the opening has a surface layer made of linear saturated polyester resin and a back layer made of polyolefin resin. an intervening member made of a laminated sheet comprising a laminated sheet and having an easy-to-break line formed at a position corresponding to the outline of the opening in the blank plate, is brought into contact with the blank plate so as to close the opening; and adhesion and fixation to the back layer of the blank board by welding ability between the back layer of the blank board and the surface layer of the intervening member at a portion along the periphery of the opening in the blank board. A blank board for a paper container, which is equipped with a pouring tool. 2. A laminated sheet for paper containers comprising a surface layer made of a polyolefin resin, an intermediate layer containing a gas barrier layer and a paper layer in the laminated structure, and a back layer made of an ethylene-vinyl alcohol copolymer resin. , a blank board for a paper container for forming a paper container in which the inner peripheral surface layer of the container is constituted by a back layer made of the laminated sheet, wherein a pouring tool is attached to the blank board at a predetermined position on the blank board; An opening is formed for insertion, and the opening is made of a laminated sheet comprising a surface layer made of an ethylene-vinyl alcohol copolymer resin and a back layer made of a polyolefin resin. An intervening member having an easy-to-break line formed at a position corresponding to the outline of the opening in the blank plate is brought into contact with the opening so as to close the opening, and Note that the portion along the periphery is bonded and fixed to the back layer of the blank board by the welding ability between the back layer of the blank board and the surface layer of the intervening member. A blank board for paper containers that is equipped with fittings.
