Title:
EASY OPEN FLEXIBLE BAG
Document Type and Number:
Japanese Patent JPH0398848
Kind Code:
A
Abstract:

PURPOSE: To solve problems on storage, handling and disposal by partially separating a corner part of a flexible box from other parts, and removing a part corresponding to a gusset panel from a closed upper end of the flexible box.

CONSTITUTION: A continuous line of weakness is arranged in a perforation line 60 in a side panel 30 and a respective perpendicular extension part 43 of a back panel and a front panel of a flexible box, and perforation parts 65-68 are arranged in a panel which is not substantially subjected to the tension force. Thus, the perforation parts 65-68 can be broken by applying the force on the relatively low level. On the other hand, side panels 30, 31 are subjected to the tension force, and the perforations or other lines of weakness to be used in the panel are resistant against the tension force. Because a compressed flexible box 10 comprises two depositions, only a part of the upper deposition is exposed by a part of the continuous perforations 60 arranged in the side panel 30. Problems on storage, handling and disposal can be solved thereby.
