Slider capable of minimizing scratching on zipper, zipper using the slider, and commercial product using the zipper

Abstract

A slider capable of minimizing scratching on zipper, which includes a top side plate, a bottom side plate opposing the top side plate, and a link part connecting the top side plate and the bottom side plate, the bottom side plate having two side walls extending from two side edges thereof, the top side plate having a top inner surface and a top outer surface, the bottom side plate having a bottom inner surface and a bottom outer surface, and an internal passage being formed by the top inner surface, the bottom inner surface, the side walls and the link part; and the slider being characterized in that a pair of parallel longitudinal grooves are formed in the top inner surface and/or the bottom inner surface during a molding process to accommodate at least a part of a set of border lines of a combination mold.

What is claimed is: 
     
         1 . A slider capable of minimizing scratching on a zipper, comprising:
 a top side plate, a bottom side plate opposing the top side plate, and a link part connecting the top side plate and the bottom side plate, the bottom side plate having two side walls extending from two side edges thereof, the top side plate having a top inner surface and a top outer surface, the bottom side plate having a bottom inner surface and a bottom outer surface, and an internal passage being formed by the top inner surface, the bottom inner surface, the side walls and the link part; and the slider being characterized in that:   a pair of parallel longitudinal grooves are formed in the top inner surface and/or the bottom inner surface during a molding process to accommodate at least a part of a set of border lines of a combination mold to contain a leaked amount of a molten raw material from the border lines, so that the slider can minimize scratching on the zipper.   
     
     
         2 . The slider capable of minimizing scratching on a zipper as disclosed in  claim 1 , further comprising at least one pull handle disposed on the top outer surface and/or the bottom outer surface. 
     
     
         3 . The slider capable of minimizing scratching on a zipper as disclosed in  claim 1 , wherein each of the top inner surface and the bottom inner surface has a set of border line marks, the set of border line marks including a pair of longitudinal border line marks, a front transverse border line mark connected to each of the longitudinal border line marks, and a rear transverse border line mark connected to each of the longitudinal border line marks. 
     
     
         4 . The slider capable of minimizing scratching on a zipper as disclosed in  claim 1 , wherein a pair of top stop receiving parts are formed on the front end of the top inner surface and/or that bottom inner surface to receive a pair of top stops of the zipper, and each of the grooves is partly disposed in one of the top stop receiving parts. 
     
     
         5 . The slider capable of minimizing scratching on a zipper as disclosed in  claim 1 , wherein the grooves each have a different width and depth. 
     
     
         6 . The slider capable of minimizing scratching on a zipper as disclosed in  claim 1 , wherein the slider is selected from the group consisting of a pinless slider, a spring-loaded pinned slider, a press-fastened pinned slider, a spring-loaded pinned slider, a spring-loaded pinned slider for invisible zippers, and a pinless slider for invisible zippers. 
     
     
         7 . The slider capable of minimizing scratching on a zipper as disclosed in  claim 1 , wherein the slider is an alloy metal slider or a plastic slider. 
     
     
         8 . The slider capable of minimizing scratching on a zipper as disclosed in  claim 1 , wherein intersections of both the front end transverse border line mark and the rear end transverse border line mark with each of the longitudinal border line marks are shaped with a beveled or rounded corner. 
     
     
         9 . A zipper including the slider as disclosed in  claim 1 . 
     
     
         10 . A commercial product having the zipper as disclosed in  claim 9  to offer a zipping operation. 
     
     
         11 . The commercial product as disclosed in  claim 10 , being selected from a group consisting of an article of clothes, an article carrier and a camping gear.
