<P>PROBLEM TO BE SOLVED: To provide a paper container for a liquid with a spout, which makes no leakage of stored contents occur from a heat molten portion of the spout constituting a plug and produces a small amount of adsorption substances derived from the stored contents. <P>SOLUTION: This is a paper container for liquid with a spout, in which the spout composed of a cap and the spout of PE material is installed in the main body of the paper container comprised of laminated material having at least a paper layer, an outer resin layer, and a sealant layer. The sealant layer has a side in contact with the stored contents made of cyclic olefin resin, and a sealed part for heat melting operation that is cooperatively arranged at one end of a hollow tubular part of the spout, and the inner surface of the main body of the paper container for a liquid, are heat melted in such a way that the polyethylene resin layer of an adhering film and the seal part face each other through an adhering film made of multi-layer co-extrusion film having the cyclic olefin resin layer and the polyethylene resin layer on each of the outer sides, and that the cyclic olefin resin layer and the inner surface of the main body of the paper container for a liquid face each other. <P>COPYRIGHT: (C)2009,JPO&INPIT |
