PAPER CONTAINER, PAPER CUP, AND METHOD FOR MANUFACTURING BOTH PAPER CONTAINER AND PAPER CUP

摘要

PROBLEM TO BE SOLVED: To provide a paper container, a paper cup and a method for manufacturing the paper container and the paper cup not producing any trouble at a covering of a paper end surface but producing a barrier characteristic showing a neat outer finished appearance. SOLUTION: This paper container is constituted such that one end edge (11) of a barrel blank at a barrel laminated portion (15) is formed in such a way that at least a thermoplastic resin layer (2) at the inner surface sticks out of a paper substrate (1) by a predetermined width to form an end edge protection resin layer (4). The end edge protection resin layer is folded back near the end part of the paper substrate. The end surface (5) of the paper substrate is covered and closely contacted with the inner surface of the other end edge (12) of the barrel blank to form a barrel laminated portion (15).
