<p><P>PROBLEM TO BE SOLVED: To provide a paper-made liquid container, which has a peek-hole having a superior gas barrier property, and enables an easy check on the residual amount of a content by peeking in through the peek-hole. <P>SOLUTION: The paper-made liquid container is made of a laminated material (10) composed of a paper base material (11), at least a gas barrier layer (12) of an intermediate layer, and an inner layer (13) of a thermoplastic resin layer having heat weldability. The container comprises a trunk (2), a top (3), and a bottom (4). The peek-hole (5) is drilled in a side face of the trunk (2), and is covered entirely with an window film (20) from the liquid content side, where fine irregular patterns (25) are formed on the surface of the window film (20) that faces the liquid content side. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
