FIELD OF THE INVENTION
The present invention relates generally to a zipper, and more particularly to a pull tab of the zipper.
BACKGROUND OF THE INVENTION
As illustrated in
FIGS. 1-3
, a prior art zipper
10
comprises a chain
11
, a slide
12
, and a pull tab
13
. The pull tab
13
is fastened at one end with the slide
12
by a fastening piece
121
. As the pull tab
13
is pulled, the slide
12
moves to join or separate two adjoining edges of the chain
11
. The fastening piece
121
is vulnerable to damage, as shown in FIG.
2
. The damage may be caused by impact or a prolonged use of the zipper
10
. In addition, the pull tab
13
is provided at one end with a fastening ring
131
for fastening the pull tab
13
with the fastening piece
121
. The fastening ring
131
of the pull tab
13
is also vulnerable to damage, as shown in FIG.
3
. It is readily apparent that the prior art zipper
10
has an inherent structural deficiency, which accounts for its short service life span. In addition, the prior art zipper
10
is often used in a luggage such that the slide
12
and the pull tab
13
are provided with a pigment coating in harmony with that of the luggage. The pigment coating of the slide
12
is susceptible to being scratched by the pull tab
13
.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a zipper with a pull tab which is free of the deficiencies of the prior art zipper described above.
The foregoing objective of the present invention is attained by a zipper pull tab comprising a main body and a fastening member which is pliable. The main body is provided at the fastening end with a retaining projection. The fastening member is provided at the free end with a retaining slot engageable with the retaining projection of the main body. In light of pliability of the fastening member, the fastening member is bent to enable the retaining slot to retain therein the retaining projection, thereby forming a receiving space in which the fastening end of a zipper slide is received.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.
