Problems solved by technology

[0002] Such a zipper forms the subject of the applicant's earlier filed application 19924539.8-26, in which the disadvantages of conventional zippers are overcome and, despite a simpler construction, perfectly seals even under pressure Liquids and gases, and last longer
However, in said early zippers, it was not entirely guaranteed that when the zipper slider was moved to close the zipper, the zipper slider would also hold the last coupler of the row of couplers in a position ensuring an airtight fluid seal

Embodiment Construction

[0018] In the conventional method, the zipper 1 shown in the drawings has two zipper support strips 2, 3 to which the coupler rows 4, 5 are sewn. The support strips 2 , 3 each comprise a textile base strip 6 , for example formed of a polymer or some other plastic. However, it is also possible for the base strip 6 to be formed from cotton threads.

[0019] Each base strip 6 has a soft elastomer covering on the side facing away from the coupler rows 4,5. However, this term includes elastomers, while thermoplastics can also be used to coat the base strip 6 .

[0020] The overlay cannot be seen in the attached drawings. Details regarding the soft cover layer and its position relative to the end surface of the base strip 6, which completely covers the base strip, can be seen from the applicant's earlier filed application 19924539.8-26. These and other purposes of the earlier filed application are to sew the continuous row of coupling elements 4,5 to the zipper support strips 2,3...

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 ...
