Description
とくに、本発明では、飲食品用包装袋の液体注出ノズルの基端辺においてベースフィルム層を挟んで積層される、それぞれのシーラント層を、ベースフィルム層縁から食み出させて相互に融着接合させることにより、その融着接合がいつの時点で行われても、軟質包装袋本体に一体的に融着接合されて軟質包装袋の一部をなす、その液体注出ノズルの、接着剤層およびアンカーコート層等の袋内包装物との接触のおそれを確実に取り除くことができるので、その袋内被包装物が飲食物であっても、常に十分な安全性、衛生性等を確保することができる。
図1は、この発明に係る液体注出ノズルの実施形態を示す図であり、図1(b)は、図1(a)に示すノズル側面図のb−b線に沿う拡大断面図である。
なお、図中斜線を施して示す部分は、表裏二枚の積層フィルムもしくは、中央部で二つに折り返してなる一枚の積層フィルムの、ノズルの基端辺となる部分を除く周縁部に設けた融着接合部1を示し、この融着接合部1は、先端融着部2を、破断もしくは切断除去することにより、融着接合部1によって、その内側に区画形成された注出流路3の先端に注出口を形成することができる。
