Corner open type zipper pack

Abstract

The present invention relates to a corner open type zipper pack ( 1 ) capable of achieving an automatic fabrication in which an opening part formed of a synthetic resin zipper ( 2 ) is formed at a corner of a pack formed of a synthetic resin seat source material. The synthetic resin zipper is thermally adhered only at one side of each of the female zipper and the male zipper with a thermal adhering wing, wherein the female and male zippers are arranged in an inner direction of the zipper pack, and the thermal adhering wing is arranged in a direction of the corner portion of the opening part for thereby achieving a thermal adhering structure, so that an automatic fabrication is obtained.

1 . A zipper pack in which the upper, lower, left and right edge portions of the surface and back surface formed of a synthetic resin seat source material are sealed by a thermal adhering method, and a synthetic resin zipper formed of female and male zippers is thermally adhered at a slanted angle to an inner side of an opening part of the corner portion of one side of upper end, an improved corner open type zipper pack comprising: 
 a synthetic resin zipper being thermally adhered only at one side of each of the female zipper and the male zipper with a thermal adhering wing, wherein said female and male zippers are arranged in an inner direction of the zipper pack, and said thermal adhering wing is arranged in a direction of the corner portion of the opening part for thereby achieving a thermal adhering structure, so that an automatic fabrication is obtained.
