<p><P>PROBLEM TO BE SOLVED: To provide a plastic zipper and a bag with plastic zipper, which carries accuracy, certainty, lightness, easiness, high sealing performance and pressure tightness of zipper closing operation and to satisfy simpleness of the zipper structure, reasonable manufacturability and low cost. <P>SOLUTION: When a male member 21 and a female member 41 are butted each other and an inductive end 28 and hook front surfaces 46a and 46b contact relatively, the inductive end 28 and the hook front surfaces 46a and 46b turn into linear contact state and the hook front surfaces 26a and 26b and 46a and 46b of both turn into non-contact state. When the inductive end 28 intervenes between both separated ends 49a and 49b and the hook front surfaces 26a and 26b and both separated ends 49a and 49b contact relatively, the hook front surfaces 26a and 26b and both separated ends 49a and 49b turn into the linear contact state. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
