Description

Anti-seepage zippers with continuous fastening elements for clothing, carrying devices or camping purposes products

This case relates to an anti-seepage zipper, especially an anti-seepage zipper with continuous fastening elements.

According to the conventional anti-seepage zipper with continuous fastening elements, a central gap is filled with an anti-seepage cover formed by an elastic colloid, so that the anti-seepage zipper has an anti-seepage function. Since the pair of support tapes of the anti-leakage zipper are made of warp and weft yarns interwoven up and down, the flatness of the inner sides A of the pair of support tapes will affect the smoothness of the appearance of the anti-seepage cover.

As shown in Figure 1, it shows the interweaving diagram of warp yarn B and weft yarn C (marked as diagonal lines) on the inner side A. From Figure 1, it can be observed that the innermost warp yarn B presents up and down waves on the inner side A. shape, and each trough, that is, the innermost warp yarn B is in a sinking position, and a concave gap D appears on the inner side A at this position; because the thickness of each support tape is made up of interwoven warp yarns and weft yarns, Therefore, the depth of the concave notch D is approximately half the thickness of each supporting cloth tape. Therefore, when the elastic colloid is injected into the central gap to form the anti-seepage covering body E, as long as the thickness of the anti-seepage covering body E is greater than the thickness of each supporting cloth tape, Half of the supporting cloth tape, the anti-seepage covering body E will inevitably pass through the concave gap D and cross the sunken innermost warp B to both sides or ooze out to the top surface of the pair of supporting cloth tapes, so that The anti-seepage covering body E creates uneven edges on the top surface of the support tape.

As shown in Figure 2, it shows a top view of each support tape. From the figure, it can be observed that the inflection point of the weft yarn C on the inner side covers the innermost warp yarn B, so each weft yarn C is on each support tape. A protruding point F is generated on the inner side A, so that the horizontal protruding point F appears on the boundary between the top surface of each support cloth belt and the inner side. The concave notch D combined with the protruding point F further highlights the uneven edges of the anti-seepage covering body E.

As shown in Figure 3, it shows a top view of the anti-seepage covering body E with a shaded part. The protruding points on both sides of the anti-seepage covering body E are the positions of the concave notches D, and the recessed parts are the Waiting for sudden change The location of point F, and the aforementioned defects lead to poor glue injection yield and poor appearance, can be called a flaw in the ointment.

The main purpose of this case is to provide an anti-leakage zipper with a continuous fastening element. Each inner surface of a pair of supporting cloth straps has a straight upright surface, and has a straight imaginary surface with the top surface of the pair of supporting cloth straps. The boundary line enables an anti-seepage covering body to be confined within a central gap of the pair of supporting fabric strips, and has a neat linear appearance.

In order to achieve the aforementioned purpose, the technical means adopted in this case is to provide an anti-seepage zipper with a continuous fastening element, which includes a pair of support tapes made of interwoven warp yarns and weft threads. Each of the pair of support tapes has a There is a top surface, a bottom surface and an inner side, and a central gap is formed between the pair of opposite inner sides of the pair of supporting cloth straps. A plurality of continuous patterns arranged in a row are sewn on an inner edge of each bottom surface. Fastening element; and an elastic colloid that fills at least the central gap to form an anti-seepage covering body, and divides the anti-seepage covering body in the central gap so that the anti-seepage zipper has an opening and closing function; characterized in that: The inner side of each support cloth tape is a continuous loop structure made of weft yarn crocheting, so that the anti-seepage covering body is limited within the pair of inner sides, and the anti-seepage covering is filled in the central gap. The imaginary boundary between the body and each medial surface has the appearance of a straight line.

In one embodiment, the weft yarns of the continuous loop weave of each support tape have an extra yarn woven together to increase the thickness of the inner side.

In one embodiment, it further includes an anti-seepage adhesive layer, which is disposed on the top surface of the pair of support cloth tapes and the anti-seepage covering body, so that the pair of support cloth tapes have an anti-seepage function.
