PROBLEM TO BE SOLVED: To determine freely and easily the size of a hole and the number of holes according to the discharging state of contents and prevent permeation of the contents through a container before a lid is unsealed and damage of the container during the unsealing, by making a discharging hole into a thin inside sheet member covering an opening or into inside and outside sheet members. SOLUTION: An opening part is made in the inclined face of the upper part of a gable top container produced from a base material B, and an inside sheet member 5 with a discharging hole 6, consisting of a group of a large number of small holes, made through it is welded to the internal face of the opening part. And an inside sheet member 7, annular body, having a hole 8 smaller than the opening part is welded to the side face of the peripheral edge of the opening part and to the surface of the inside sheet member 5 and, further, a lid 3 is welded to the peripheral edge of an outside sheet member 7 so as to be freely peelable. Because the end face of the opening of the container is protected with the inside and outside sheet members 5 and 7, respectively, contents are prevented from permeating through the container. Also, even when the lid 3 is unsealed, the vicinity of the discharging hole 6 is not damaged because the lid 3 is not welded to the part having the discharging hole 6. |
