Bag, has flange provided on external face of one of sheets near hold zone of slider and presented in form of strip constituting over-thickness, thickness and width that are sufficient for locally modifying deformability of bag

摘要

The bag (1) has two parallel sheets (12, 13) for forming main walls, and male and female sections (2, 3) that are fixed on the sheets, respectively. A slider (5) activates the sections for closing and opening the sections. A flange (6) is provided on an external face of one of the sheets near a hold zone of the slider and parallel to a displacement direction of the slider. The flange made of a deformable rubber base material is presented in the form of a strip constituting an over-thickness, a thickness and a width that are sufficient for locally modifying deformability of the bag.
