Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This is the U.S. National Stage of International Application
No. PCT/CN2018/081111 filed on Mar. 29, 2018, which in turn claims
the benefit of Chinese Application No. 201720332454.8, filed on
Mar. 30, 2017 all of which are incorporated herein by reference in
their entirety.
BACKGROUND OF THE INVENTION
[0002] The disclosure relates to a zipper, and in particular, to a
water-resistant zipper.
[0003] A water-resistant zipper is popular since liquid can be
prevented from passing through the zipper and the water-resistant
zipper plays a water-resistant sealing role. The water-resistant
zipper mainly relies on a water-resistant layer disposed on a base
tape to achieve the water-resistant sealing effect. In general,
zipper teeth are first connected to a base tape during processing
of the water-resistant zipper, and then the base tape is provided
with a water-resistant layer. When the water-resistant zipper is
processed using this method, it is difficult for the
water-resistant layer to completely cover the base tape due to the
influence of the installed zipper teeth. Especially due to gaps
between the zipper teeth on the base tape, it is difficult for the
water-resistant layer to cover the base tapes at these gaps, so
that the water-resistant effect of the zipper is poor, and it is
also troublesome to process the water-resistant layer.

BRIEF DESCRIPTION OF THE DRAWINGS
[0017] The disclosure will be further described below in
conjunction with accompanying drawings and embodiments.
[0018] FIG. 1 is a schematic diagram of an overall structure of the
disclosure;
[0019] FIG. 2 is a schematic diagram of a cross section of the
disclosure;
[0020] FIG. 3 is a schematic structural diagram of zipper teeth of
the disclosure; and
[0021] FIG. 4 is a schematic diagram of a cross section of another
embodiment of the disclosure.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0022] Referring to FIGS. 1 to 4, the disclosure relates to a
water-resistant zipper including two zipper tapes 2 and two groups
of zipper teeth 1 respectively disposed on the two zipper tapes 2.
The zipper tape 2 includes a base tape 21 and a water-resistant
layer 22 covering the base tape 21; that is, the zipper teeth 1 are
located on the water-resistant layer 22. For the water-resistant
zipper of the disclosure, the water-resistant layer 22 is first
disposed on the base tape 21 during processing, and then the zipper
teeth 1 are disposed on the water-resistant layer 22. The
arrangement of the water-resistant layer 22 is not affected by the
zipper teeth 1, and the water-resistant layer 22 can easily cover
the whole base tape 21. The water-resistant zipper of the
disclosure is simple to process and good in water-resistant
effect.
[0023] Ends of the two zipper tapes 2 are connected together. The
ends of the two zipper tapes 2 can be sewn together by means of a
sewing machine and the joint is covered with a sealant, or the ends
of the two zipper tapes 2 can be connected by injection molding, so
that the end of the zipper can be well sealed to prevent liquid
from passing through the end of the zipper.
[0024] The end of the zipper tape 2 has an accommodating cavity 23
for accommodating a zipper slider. When the zipper slider is
mounted on the zipper and the zipper slider is moved to the end of
the zipper tape 2, the zipper slider is located in the
accommodating cavity 23. There is no gap between the zipper slider
and the zipper tape 2 to ensure the water-resistant sealing effect,
and the zipper is simple in structure and attractive in
appearance.
[0025] A mounting groove in communication with front and rear end
faces of the zipper tooth 1 is formed on the inner side of the
zipper tooth 1, and the inner sides of the zipper tapes 2 extend
into the mounting grooves so that after the zipper teeth 1 on the
two zipper tapes 2 mesh with each other, the inner sides of the two
zipper tape 2 can be closely attached together to form a combined
sealing layer that prevents liquid from passing through the
zipper.
[0026] In the disclosure, the zipper teeth 1 are formed on the
zipper tape 2 by injection molding. The zipper tape 2 has a
longitudinal fixed through hole, and the fixed through hole is
filled with melt when the zipper tooth 1 is formed by injection
molding, so that the finally shaped zipper tooth 1 has a
reinforcing portion filling the fixed through hole 12. The
reinforcing portion 12 can make the connection between the zipper
teeth 1 and the zipper tape 2 stronger. Preferably, the fixed
through hole is in a diamond shape or a square shape, that is, the
cross section of the reinforcing portion 12 is also in a diamond
shape or a square shape. Compared with the circular fixed through
hole, the diamond or square fixed through hole can avoid the
torsion motion of the zipper tooth 1 relative to the zipper tape 2,
which greatly enhances the bonding force between the zipper tooth 1
and the zipper tape 2, and moreover, the separation of the
water-resistant layer 22 from the base tape 21 caused by the
torsion of the zipper tooth 1 can be avoided, the compactness of
the water-resistant layer 22 and the base tape 21 combined with
each other is enhanced, and the original air tightness of the
disclosure is improved simply and effectively.
[0027] The zipper tooth 1 is provided with a boss 11, and the boss
11 abuts against the zipper tape 2. The boss 11 can increase the
contact area between the zipper tooth 1 and the zipper tape 2,
making the connection between the zipper tooth 1 and the zipper
tape 2 stronger. In addition, the boss 11 also has a limiting
function. After the zipper teeth 1 on the two zipper tapes 2 mesh
with each other, the boss 11 on one zipper tape 2 abuts against the
zipper teeth 1 on the other zipper tape 2, thereby limiting the
longitudinal relative movement of the two groups of zipper teeth 1
on the two zipper tapes 2.
[0028] The surface of the water-resistant layer 22 is coated with a
fluorescent layer or a reflective layer. In this way, the zipper is
more striking and attractive at night, enhancing the roles of
warning and decoration, helping users to understand the opening and
closing of the zipper, and helping users to find the zipper in the
dark.
[0029] Further, referring to FIG. 4, in another embodiment of the
disclosure, the inner side of the zipper tape 2 is provided with an
elastic tape edge 3, and the elastic tape edge 3 itself is
elastically deformable, so that the two zipper tapes 2 can be
closely attached to avoid the existence of gaps between the two
zipper tapes 2 and further improve the water-resistant sealing
effect. The elastic tape edge 3 and the water-resistant layer 22
are made of different colors or materials to make the zipper tape 2
more attractive.
[0030] The above embodiments are merely preferred embodiments of
the disclosure, and other embodiments of the disclosure are
possible. Equivalent variations or substitutions may be made by
those skilled in the art without departing from the principle of
the disclosure, and such equivalent variations or substitutions
fall within the scope set by the claims of the present
application.
[0031] It is understood that while certain aspects of the disclosed
subject matter have been shown and described, the disclosed subject
matter is not limited thereto and encompasses various other
embodiments and aspects. No specific limitation with respect to the
specific embodiments disclosed herein is intended or should be
inferred. Modifications may be made to the disclosed subject matter
as set forth in the following claims.
