Abstract
A cap structure for a zipper includes a cap and a resilient tab. The cap has a containing groove formed on the bottom surface thereof. At least one lug is disposed on the bottom surface of the containing groove. The bottom of the concave portion is lower than the top of the lug. Two sides of the cap each have a side wall. Each of the side walls has a recess opening that communicates with the containing groove. The resilient tap is disposed within the containing groove and the resilient tap abuts against the limiting portions. One end of the resilient tap has an aperture that corresponds to the lug. Therefore, the resilient tap and cap are combined to form the cap structure. Because the space for the resilient tap to bend is bigger, the force for pulling the slide of the zipper is smaller.

The slide of the zipper structure includes a zipper slide, a pull tab, a hook, a resilient tap, and a cap. The top of the slide of the zipper has two holding bases. A hole of the pull tab is looped around one of the holding bases of the zipper slide. The hook is disposed movably inside of the zipper slide. The resilient tap is disposed on the slide of the zipper and attached to the top of the hook. Furthermore, the cap is covered on the pull tab to lock the resilient tap inside the cap. The top of the pull to passes through a concave portion of the cap.
- When a user wants to close or separate the interlocking teeth of the zipper tape, the user needs to pull the pull tab so that the hook pulls the resilient tap. Therefore, a blocking portion of the hook is removed from the interlocking teeth of the zipper tape. The pull tap pulls the slide of the zipper structure to close or separate the interlocking teeth of the zipper tape.
- However, when a manufacturer has to assemble the resilient tap with the zipper slide, and then cover the cap on the slide of the zipper to assemble the zipper slide. The assembly of the slide of the zipper is complex and inconvenient. Moreover, a user must use a large force to pull the pull tab to bend the resilient tab. The pulling of the pull tab is difficult.
- It is an object of the present invention to provide a cap structure for a zipper. The cap and the resilient tap are combined previously for assembling the slide of the zipper easier. The resilient tap has an aperture, and the cap has a concave. Therefore, the resilience of the resilient tap is increased, the resilient tap has more space to allow for bending, and the force required to pull the slide of the zipper is less.

In this embodiment, the two limitingportions 152 are disposed in a diagonal position. However, the position of thelimiting portions 152 is not limited. The two limitingportions 152 are disposed in opposite positions. - The
resilient tap 20 is made of resilient metal material. The opposite ends of theresilient tap 20 each have anaperture 21. Theapertures 21 correspond to thelugs 13. Theapertures 21 pass through a top and a bottom of theresilient tap 20 to increase the resilience theresilient tap 20. In this embodiment, the receivingportions 21 are apertures. However, the receivingportions 21 can be groove and pass through the surfaces of the opposite ends respectively, as shown inFIG. 6 . The middle of theresilient tap 20 is bent downwardly to form acontact portion 22. - When assembling the
cap structure 1 of the present invention, theresilient tap 20 is disposed within the containinggroove 12. The surface of theresilient tap 20 abuts against the limitingportion 152 to prevent theresilient tap 20 dropping out of the containinggroove 12 of thecap 10. Therefore, theresilient tap 20 is assembled with thecap 10. - Please refer to
FIG. 5 . When theresilient tap 20 is bended by a force, thelugs 13 respectively pass through the receivingportions 21 to protrude out of theresilient tap 20. Because the bottom of the concave portion 14 (please refer toFIG. 2 ) is lower than the top of thelugs 13, the two ends of theresilient tap 20 can contact the bottom of the containinggroove 12. - Please refer to
FIGS. 7 to 9 . Thecap structure 1 of the present invention can be assembled to a slide of asemi-finished zipper 2 to form a zipper slide. The slide of thesemi-finished zipper 2 includes a zipper slide, apull tab 40, and ahook 50. - The opposite ends of the top surface of the slide of the
zipper 30 have afirst holding base 31 and asecond holding base 32 respectively. Thefirst holding base 31 and thesecond holding base 32 each have afirst recess 311 and asecond recess 321. Between thefirst holding base 31 and second holdingbase 32 there is acavity 33. The bottom surface of thecavity 33 has ahook hole 34. The slide of thezipper 30 has a slidinggroove 35. The slidinggroove 35 passes through the two ends of the slide of thezipper 30 and communicates with thehook hole 34. - One end of the
pull tab 40 has ahole 41. Thepull tab 40 has aterminal portion 42 at the end near thehole 41. - One end of the
hook 50 has afront portion 51, and a second end of thehook 50 has aback portion 52. Between thefront portion 51 and theback portion 52, thehook 50 has a concave curvedmiddle portion 53. Themiddle portion 53 has a blockingportion 54. - When a manufacturer wants to assemble the slide of the zipper structure, the manufacturer can follow the steps as described below. First, the
terminal portion 42 of thepull tab 40 is disposed in thecavity 33 of the zipper-slide 30, and thehole 41 of thepull tab 40 is put around thefirst holding base 31 or thesecond holding base 32. - Next, the
hook 50 is attached on thefirst holding base 31 and thesecond holding base 32. Thefront portion 51 of thehook 50 is disposed in thefirst recess 311 of thefirst holding base 31. Theback portion 52 of thehook 50 is attached to the bottom of thesecond holding base 321 of thesecond holding base 32. Themiddle portion 53 of thehook 50 is attached to theterminal portion 42 of thepull tab 40. The blockingportion 54 ofhook 50 is disposed in the slidinggroove 35 of the slide of thezipper 30 via thehook hole 34 between thefirst holding base 31 and second holdingbase 32. Therefore, the slide of thesemi-finished zipper 2 is completed. - Please refer to
FIG. 9 . Thecap structure 1 of the present invention can be covered on the slide of thesemi-finished zipper 2. Thehook 50 and thefirst holding base 31 and thesecond holding base 32 of the slide of thezipper 30 are disposed within thecap 10. Theterminal portion 42 of thepull tab 40 passes through the tworecess openings 151 of thecap 10. Thecontact portion 22 of theresilient tap 20 attaches to thehook 50 to form a slide of the zipper structure. The slide of the zipper structure is hooked via a blockingportion 54 hooked in interlocking teeth of a zipper tape (not shown in the figure). Therefore, the slide of the zipper structure is stuck when thepull tab 40 is not being pulled. - When the
pull tab 40 is pulled, thehook 50, which is attached to theterminal portion 42 of thepull tab 40, pushes theresilient tap 20 upwardly. At the same time, the blockingportion 54 is pulled out of the interlocking teeth of the zipper tapes. Therefore, thepull tab 40 can pull the slide of the zipper structure moving along the zipper tapes for closing or separating the zipper tapes. - When the
pull tab 40 is released, thehook 50, which is attached to theterminal portion 42 of thepull tab 40, releases the force of pushing theresilient tap 20. Therefore, the blockingportion 54 of thehook 50 hooks the interlocking teeth of the zipper tapes, and the zipper tapes are locked. - In conclusion, the limiting
portion 152 of thecap 10 installs thecap 10 in theresilient tap 20 to combine theresilient tap 20 andcap 10 to thecap structure 1. When a manufacturer assembles the zipper slide, the manufacturer just assembles thecap structure 1 on the slide of thezipper 30. Therefore, the assembly of a slide of the zipper is simpler. - Moreover, the two ends of the
resilient tap 20 have the receivingportion 21 to increase the resilience of theresilient tap 20. The inside of thecap 10 has theconcave portion 14 for theresilient tap 20 to allow bend. Therefore, a user just uses a small force to push thepull tab 40 to bend theresilient tap 20 and pull up the hook moving. Furthermore, the slide of the zipper is moved easier. - The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
