Description
BACKGROUND OF THE INVENTION
[0001] (a) Technical Field of the Invention
[0002] The present invention relates to a decorative zipper tab
construction with an elastic string of high tension, particularly
to one comprising an elastic element which, by way of an extrusion
of the holding base, can be firmly covered inside of the decorative
tab and thereby lasting the life of use of the zipper. In addition,
the user may draw the zipper smoothly by simply pulling the
decorative tab.
[0003] (b) Description of the Prior Art
[0004] Conventional zipper tab decorative structure as disclosed in
R.O.C. Patent No. 340313 comprises an upper cover, a lower cover,
and a strip conjuncted to and in-between said covers. The upper
cover has a shape corresponding to that of the lower cover, while
corresponding depressions and extrusions are properly distributed
on the upper and lower covers. Said prior art is characterized in
that: Supersonic welded plastic bars extrude from the center of the
three edges of a cover, while a groove is provided at a portion
adjacent to the end of each of the two covers for receiving the
blunt head of a strip. A plurality of awl-shape pins are provided
inside of one cover adjacent to the front end, whereas
corresponding cushions are provided on another cover such that the
blunt head of the strip, which is cut by way of heat scissors, can
be received in the groove in-between the two covers. Said two
covers are further processed by supersonic welder to integrally
conjunct with each other and be sealed to fasten after being
pierced into the zipper tab to form a zipper tab stamped with the
trademark.
[0005] Although the above-mentioned zipper tab decorative structure
can be seamed with the zipper tab and stamped with the trademark
for advertisement purposes, said zipper tab decorative structure
can be dismantled from the zipper tab after being conjunct
therewith. In such a case, when the user inadvertently tear the
decorative structure apart from the zipper tab, the zipper tab
would never be used again. Accordingly, the utility of the
conventional zipper tab decorative structure is very limited.
SUMMARY OF THE INVENTION
[0006] The primary object of the invention is to provide a
decorative zipper tab construction with an elastic string of high
tension which, by way of the extrusion of the holding base, can be
firmly covered inside of the decorative tab and thereby lasting the
life of use of the zipper.
[0007] Another object of the invention is to provide an improved
decorative zipper tab construction, which comprises a holding base
having an extrusion on the top, an elastic element mounted on the
extrusion of the holding base. A locking device is provided at one
end of the elastic element for holing both ends of the elastic
string and making the string become a closed ring. The locking
device mounted on the elastic element can be alternatively fastened
by a string, adhesive or pin.
[0008] A decorative tab is disposed on the outer of the holding
base for covering the holding base the elastic element by way of
the extrusion of the holding base. Accordingly, the elastic element
can be firmly covered inside of the decorative tab and thereby
lasting the life of use of the zipper. In addition, the user may
draw the zipper smoothly by simply pulling the decorative tab.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] Referring to FIGS. 1, 2 and 3, the present invention is a
decorative zipper tab construction with an elastic string of high
tension, which comprises a holding base 1, an elastic element 2 and
a decorative tab 3. The elastic element 2, by way of the holding
base 1, can be filmy covered inside of the decorative tab 3. While
the elastic element 2 with high tension can bear the pulling force,
the life of use of the zipper tab can be lasted. In addition, the
user may draw the zipper smoothly by simply pulling the decorative
tab.
[0015] An extrusion 11 is provided at the center of the holding
base 1 mentioned above.
[0016] The elastic element 2 can be an elastic string, and one end
thereof is provided with a locking device 21, which has a holder
211 at each side for fastening to one end of the elastic element 2.
Stopped at the edge of the locking device 21, the elastic element 2
can be mounted on the extrusion 11 of the holding base 1.
[0017] The decorative tab 3 is disposed on the outer of the holding
base 1, such that the extrusion 11 of the holding base I and the
locking device 21 of the elastic element 2 can be firmly covered in
the decorative tab 3. The surface of the decorative tab 3 can be
imprinted with scripts or trademark 31 when required. Accordingly
to the above mentioned, an improved zipper tab is formed.
[0018] Referring to FIGS. 4 and 5, the decorative tab 3 is formed
after making a mold 4, which has an upper mold 41 and a lower mold
42 respectively having a receiving portion 411, 421. A graphic
portion 43 is provided on the inner surface of the upper mold 41,
while a sprue 44 passing through to the receiving portion 411, 421
is provided on one end of the mold 4. To cover the extrusion 11 of
the holding base 1 and the locking device 21 of the elastic element
2 via the decorative tab 3, the holding base 1 is disposed in the
receiving portion 421 of the lower mold 42, and then the locking
device 21 of the elastic element 2 is mounted on the extrusion 11
of the holding base 1, such that the elastic element 2 can be
stopped at the edge of the locking device 21 and fastened at the
extrusion 11. After the upper mold 41 and the lower mold 42 are
combined together, an appropriate plastic material is injected
through the sprue 44 to the mold. A decorative tab 3 is formed
after separating the upper mold 41 from the lower mold 42. Thereby,
the extrusion 11 of the holding base 1 and the locking device 21 of
the elastic element 2 can be covered inside of the decorative tab
3. In addition, required scripts or trademark 31 can be formed on
the surface of the decorative tab 3 via the graphic portion 43.
[0019] After the present invention is mounted on a zipper tab (not
shown) for use, the user can simply draw the decorative tab 3 to
move the elastic element 2, and the zipper tab as well. Meanwhile,
as the elastic element 2 is fastened to the extrusion 11 by the
edge of the locking device 21, it can be firmly covered inside of
the decorative tab 3 without departing from the elastic element 2
due to the pulling force of the user, thereby lasting the life of
use of the decorative tab. In addition, the user may draw the
zipper smoothly by simply pulling the decorative tab.
[0020] As the elastic element 2 covered by the decorative tab 3 can
be an elastic string, when pulling the string, the combination
portion A will become narrowed. However, due to the provision of
the locking device 21 and the extrusion 11 inside of the decorative
tab 3, the sting with high tension would not fall out.
[0021] Concluded the above, the present invention primarily relates
to an elastic string which is combined to a locking device at the
end thereof and fastened to an extrusion of a precasted holding
base. After secondly injecting plastic material to form a
decorative tab 3 to firmly and integrally combine with the holding
base, the scripts or trademark can be imprinted on the surface of
the decorative tab as desired. The invention may serve the purposes
of utility, decoration and advertisement.
[0022] The above descriptions are of exemplary embodiments only,
and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
