縦襞付き紙製容器及びその成型方法

Vertically creased paper container and molding method therefor

Abstract

【課題】 本発明は縦襞構造をしっかりと有し、厚手の紙のみならず極めて薄い薄手の紙にも縦襞構造を成型でき、更には成型上の歩留まりもよく簡単に成型可能な縦襞付き紙製容器の提供を課題とする。 特に、紙力例えば抗張力の小さい用紙を用いても縦襞付き紙製容器を簡単かつしっかりと成型可能とする容器及び成型方法の提供を課題とする。 【解決手段】 係る課題を解決するため予め紙製容器の開口部の縦襞分の折り込みの長さを略扇状の側筒用紙の上端辺部に有する側筒用紙と底面部とによって側壁が平面状の所定の開口口径よりも口径の大きい紙製容器を構成し、該開口口径が大きい紙製容器の側壁に縦襞を構成して所定の開口口径を有する縦襞付き紙製容器によって解決できる。 【選択図】 図1
<P>PROBLEM TO BE SOLVED: To provide a vertically creased paper container which has a firm vertical crease structure, allows molding of the vertical crease structure not only on a thick paper but also on an extremely thin paper, achieves fine yield in molding, and can be molded easily, and especially to allow easy molding of a firm vertically creased paper container even if a paper with a small strength, such as small tensile force, is used. <P>SOLUTION: An almost fan-shaped side cylinder paper has an upper end side having a length equal to that of the creased circumference of an opening of a paper container. This side cylinder paper is combined with a bottom portion to form a paper container which has a flat side wall and an opening bore larger than a given opening bore. Vertical creases are formed on the side wall of the paper container having the larger opening bore to form the vertically creased paper container with the given opening bore. <P>COPYRIGHT: (C)2007,JPO&INPIT
