Claims

[Claims for Utility Model Registration] 1. A polyolefin-based product that has a recessed portion and a flange extending from the periphery of the recessed portion, and an adhesive member is thermally bonded to the back surface of the recessed portion and the flange. A spout member integrally molded from resin is attached to an opening formed in a paper container, and a flange of the spout member is thermally bonded to the outer peripheral surface layer of the paper container. and a sealing member for closing the opening of the paper container is thermally bonded to an inner peripheral surface layer of the paper container, wherein the paper container is made of ethylene-vinyl By a laminated sheet for paper containers comprising an inner surface layer comprising an alcohol copolymer resin layer as the innermost surface layer, an intermediate layer comprising a paper composite base material layer, and an outer surface layer comprising a polyolefin resin, The inner surface layer of the laminated sheet is formed to serve as the inner surface layer of the container, and a portion of the concave portion of the spout member is removed by cutting out a portion of the concave portion. Equipped with easy-to-break grooves to form an opening for pouring.
Furthermore, the sealing member is composed of an unstretched sheet of ethylene-vinyl alcohol copolymer resin, and further, the adhesive member is composed of a polyolefin resin layer and an ethylene-vinyl alcohol copolymer resin layer. A paper container having a spout member, wherein the polyolefin resin layer is thermally bonded to the spout member, and the ethylene-vinyl alcohol copolymer resin layer is thermally bonded to the sealing member. . 2. The sealing member is composed of a laminated sheet consisting of an unstretched ethylene-vinyl alcohol copolymer resin layer/a gas barrier layer/an unstretched ethylene-vinyl alcohol copolymer resin layer, and The one unstretched ethylene-vinyl alcohol copolymer resin layer is in contact with the inner peripheral surface layer of the paper container and the adhesive member on the back surface of the concave portion of the spout member, and the sealing member is attached to the paper container. A paper container having a spout member according to claim 1, wherein the inner peripheral surface layer and the back surface of the concave portion of the spout member are thermally bonded. 3. The adhesive member is composed of a laminated sheet consisting of a polyolefin resin layer/gas barrier layer/unstretched ethylene-vinyl alcohol copolymer resin layer, and the polyolefin resin layer of the adhesive member is attached to the concave shape of the spout member. 2. A paper container having a spout member according to claim 1, wherein the unstretched ethylene-vinyl alcohol copolymer resin layer of the adhesive member is thermally bonded to the sealing member on the back surface of the paper container.
