AI Technical Summary

Benefits of technology

The invention is a waterproof fastener tape that has a cord and a fabric tape portion coated with a waterproof layer. This improves its ability to prevent water from penetrating it. Additionally, the tape does not deform, making it easier to form and position scoops accurately on it.

Problems solved by technology

The waterproof tape does not include a cord, therefore it is difficult to properly position the waterproof tape.
In addition, it is impossible to visually observe whether the edge of the waterproof tape in a mold cavity of a mold is in complete contact with the mold before formation of the scoops.
The installation of the scoops 73 is difficult, and the scoops 73 cannot be accurately aligned with each other along the scoop engagement portion.
Thus, the liquid-tight slide fastener 9 can only prevent the permeation of the water in a small rain or can only form a water-diverting effect.
The conventional liquid-tight slide fastener 9 cannot provide a proper liquid-tight effect.

first embodiment

[0035]FIGS. 5 and 6 show a waterproof fastener tape of a watertight slide fastener according to the invention. The waterproof fastener tape includes a fabric tape 1 and a waterproof layer 2. The surfaces of the fabric tape 1 are covered by the waterproof layer 2.

[0036]The fabric tape 1 is a tape formed by weaving or knitting fibers. The fabric tape 1 includes a first surface 1a and a second surface 1b. A cord portion 11 protrudes from the first surface 1a of the cord portion 11. The cord portion 11 is relatively adjacent to an inner edge 1c of the fabric tape 1. An extension portion 12 is formed between the cord portion 11 and the inner edge 1c. The second surface 1b is planar.

[0037]The waterproof layer 2 is formed by an elastomeric resin material. The first surface 1a, the second surface 1b, the cord portion 11, and the inner edge 1c and an outer edge 1d that are connected between the first surface 1a and the second surface 1b, are coated with the elastomeric resin material. Thus, ...

second embodiment

[0042]FIG. 11 shows a waterproof fastener tape of a watertight slide fastener according to the invention. The first surface 1a is provided with a first cord portion 11, and the second surface 1b may be provided with a second cord portion 11. The first and second cord portions 11 are aligned with each other. One of the first and second cord portions 11 can be placed in a cord-shaped groove of a lower mold that is used to form the scoops 4. Furthermore, since the through-holes 31 also extend through the waterproof fastener tape 3 and at least one portion of the first cord portion 11 and since the upper and lower portions of the scoops 4 are symmetrically positioned with respect to each other, each of the through-holes 31 is precisely located at the center of a corresponding scoop 4 without asymmetry between the upper and lower portions of the corresponding scoop 4. Advantageously, an improved waterproof effect is attained. Furthermore, since each of the through-holes 31 extends throug...

Abstract

A waterproof fastener tape of a watertight slide fastener includes a fabric tape and a waterproof layer. The fabric tape includes a first surface, a second surface, a first edge, a second edge, a first cord portion, and an extension portion. The first cord portion protrudes from the first surface. The first and second edges are connected between the first and second surfaces. The first cord portion is spaced from the first edge at a smaller distance than from the second edge. The extension portion extends between the first edge and the first cord portion. The second surface is planar. The waterproof layer covers the first surface, the second surface, the first cord portion, the first edge and the second edge.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The application claims the benefit of Taiwan application serial No. 106126591, filed on Aug. 7, 2017, and the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention generally relates to a waterproof fastener tape and a watertight slide fastener using the waterproof fastener tape and, more particularly, to a waterproof fastener tape that is formed by a tape having a cord in which the tape is provided with a waterproof layer and includes a plurality of scoops that can be conveniently and precisely attached thereto, as well as a watertight slide fastener including the waterproof fastener tape.2. Description of the Related Art[0003]A weaved or knitted fabric tape can be provided with a waterproof function by coating an elastomeric material therewith (such as rubber), as it has been adopted by the manufacturers for decades. FIG. 1 shows a waterproof slide fa...
