Zipper

Abstract

A zipper includes male female teeth elements each having a split tube-like base fastened to a cylindrical flange at one side of a first zipper tape and a hollow receiving portion extending from the periphery of the respective split tube-like base and provided with a hook hole at an outer side, female teeth elements each having a split tube-like base fastened to the cylindrical flange of a second zipper tape and a hook strip extending from the periphery of the respective split tube-like base, and a slider body with a guide groove for guiding the hook strips of the male teeth elements into and out of the hook holes of the hollow receiving portions of the female teeth elements accurately without deviation.

1 . A zipper comprising two zipper tapes, said zipper tapes each having a cylindrical flange extending along the length thereof at one side, a plurality of male teeth elements mounted on the cylindrical flange of one of said zipper tapes and arranged in series, a plurality of female teeth elements mounted on the cylindrical flange of the other of said zipper tapes and arranged in series corresponding to said male teeth elements, and a slider body movable over said male teeth elements and said female teeth elements in reversed directions to lock and unlock said male teeth elements and said female teeth elements, wherein:
 said female teeth elements each comprise a split tube-like base fastened to the cylindrical flange of the associating zipper tape, a hollow receiving portion extending from the periphery of the split tube-like base of the respective female teeth element, and a hook hole on an outer side of said hollow receiving portion;   said male teeth elements each comprise a split tube-like base fastened to the cylindrical flange of the associating zipper tape, and a hook strip extending from the periphery of the split tube-like base of the respective male teeth element and guidable by said slider body into and out of the hook hole on the hollow receiving portion of the associating female teeth element.   
   
   
       2 . The zipper as claimed in  claim 1 , wherein said male teeth elements each comprise two clamping strips extending from the respective split tube-like base and respectively clamped on top and bottom surfaces of the associating zipper tape to affix the respective male teeth element to the associating zipper tape. 
   
   
       3 . The zipper as claimed in  claim 1 , wherein said male teeth elements each have at least one hole cut through the periphery of the respective split tube-like base. 
   
   
       4 . The zipper as claimed in  claim 1 , wherein the hook strip of each of said male teeth elements has a bend portion extending from the periphery of the split tube-like base and a hook portion extending from one end of said bend portion remote from the split tube-like base of the respective male teeth element. 
   
   
       5 . The zipper as claimed in  claim 1 , wherein said female teeth elements each comprise two clamping strips extending from the respective split tube-like base and respectively clamped on top and bottom surfaces of the associating zipper tape to affix the respective male teeth element to the associating zipper tape. 
   
   
       6 . The zipper as claimed in  claim 1 , wherein said female teeth elements each have at least one hole cut through the periphery of the respective split tube-like base. 
   
   
       7 . The zipper as claimed in  claim 1 , wherein said slider body comprises a guide groove for guiding the hook strip of each of said male teeth elements in and out of the hook holes of the associating female teeth elements. 
   
   
       8 . The zipper as claimed in  claim 1 , wherein said male teeth elements and said female teeth elements are independent elements separately fastened to said zipper tapes. 
   
   
       9 . The zipper as claimed in  claim 1 , wherein said male teeth elements are formed integrally in a single piece; said female teeth elements are formed integrally in a single piece. 
   
   
       10 . The zipper as claimed in  claim 1 , wherein said male teeth elements are integrally connected together before installation in the associating zipper tape; said female teeth elements are integrally connected together before installation in the associating zipper tape. 
   
   
       11 . The zipper as claimed in  claim 1 , wherein said male teeth elements are made in integrity from a metal plate by means of metal stamping; said female teeth elements are made in integrity from a metal plate by means of metal stamping. 
   
   
       12 . The zipper as claimed in  claim 1 , wherein the split tube-like bases of said male teeth elements and said female teeth elements are respectively tightly clamped on the cylindrical flanges of said zipper tapes. 
   
   
       13 . The zipper as claimed in  claim 1 , wherein the split tube-like bases of said female teeth elements cover the periphery of the cylindrical flange of the associating zipper tape such that said receiving portions of said female teeth elements are kept in an enclosed status relative to the cylindrical flange of the associating zipper tape. 
   
   
       14 . The zipper as claimed in  claim 1 , wherein said clamping strips of said male teeth elements and said female teeth elements each have a plurality of spurs protruded from an inner surface thereof and respectively engaged into said zipper tapes. 
   
   
       15 . The zipper as claimed in  claim 1 , wherein the split tube-like bases of said male teeth elements and said female teeth elements each have a plurality of spurs protruded from two ends thereof and respectively engaged into said zipper tapes.
