PURPOSE: To prevent a closing element for connection from being damaged or twisted by enclosing a zipper in a thermoplastic film by providing at least one highly compressive member which can be engaged with one section of the other profile, on one or both profiles. CONSTITUTION: A highly compressive member comes into contact with a wedge-form highly compressive member(28) of a male type profile(12) located on the opposite side, when profiles are connected and pressed together. By the compressing action, a highly compressive member(30) located at the center of the male type profile(12), comes into contact with the internal surface of a base(22) of a female type profile. By the contact action, the tip ends(36 and 37) of male type connecting members(18 and 20) come into contact with the female type profile(14). Thus, the connecting members are prevented from being twisted or crushed by the highly compressive member, and the profiles can be sealed to a thermoplastic film in a manner to go across the width section of the bases of the profiles. |
