Abstract

The present invention aims at providing a sealing zipper which, with a relatively simple structure, also ensures absolute fluid tightness even in the region of the slider of the zipper. A pair of zipper support strips (2, 3) of the sealed zipper (1) are further provided with a flexible cover at the connected end portion above the guide edge (14), the size of which is limited to make the slider (10) smoothly Elastomer that is guided and has the necessary compressive force to ensure a seal. And, on the side away from the joint ends of the above-mentioned zipper support tapes (2, 3) away from the coupler row (4, 5), due to the formation of a suitable size, elastic, engaged in the slider (10 ) is a U-shaped elastic cam (21) on the underside of the upper plate (12), so the slider (10) can slide smoothly at the connected ends of the support belts (2, 3), and can ensure an absolutely reliable seal sex.

Description

technical field

[0001] The present invention relates to a sealing zipper having a pair of sealing zipper support strips comprising in each case a base strip with a soft covering of elastomer, thermoplastic or the like, which covers the Cover at least one surface, and in each case, sew a continuous row of coupling elements to the support strip at a position transversely offset relative to the longitudinal edges of the support strip, such that the opposite edges of the soft cover are along the longitudinal The planes touch each other, and the longitudinal plane intersects the zipper at the central axis of the zipper and is at right angles to the main plane of the zipper, but the opposite edge protrudes above said longitudinal plane to such an extent that when the coupler row is disengaged and When the coupler row is engaged, the opposite edge is bent away from the side carrying the coupler row and extends approximately at right angles to the main plane of the zipper, protruding ...
