High strength slider end stop

Abstract

A zipper for a reclosable bag is disclosed, wherein the end stops of the zipper are formed with a dot of hot glue or adhesive. These end stops are designed to limit the range of travel of the slider and prevent the slider from being removed from the zipper. Additionally, a vertical wall facing the slider is formed to prevent the slider from riding over the end stop.

1 . A zipper for a reclosable bag including: 
 a first profile;    a second profile;    a slider which, when moved in a first direction along said first and second profiles, separates said first profile from said second profile and, when moved in a second direction opposite to said first direction, interlocks said first profile to said second profile;    end stops for restricting movement of said slider, said end stops formed on said first profile by depositing glue on said first profile, said end stops having a wall substantially perpendicular to said first and second profiles facing said slider.    
   
   
       2 . The zipper of  claim 1  wherein each of said end stops is formed from a dot of hot glue.  
   
   
       3 . The zipper of  claim 2  wherein said end stops are formed proximate to ends of said first profile.  
   
   
       4 . The zipper of  claim 2  wherein said end stops are formed proximate to ends of said first profile and said second profile.  
   
   
       5 . The zipper of  claim 4  wherein said walls are formed by a reciprocating blunt end.  
   
   
       6 . The zipper of  claim 5  wherein said reciprocating blunt end includes a stick resistant surface.  
   
   
       7 . The zipper of  claim 6  wherein said stick resistant surface includes polytetrafluoroethylene.  
   
   
       8 . The zipper of  claim 1  wherein said walls are formed by a blade.  
   
   
       9 . The zipper of  claim 1  wherein said walls are formed by a grinding element.  
   
   
       10 . The zipper of  claim 1  wherein a gas stream is impinged against said end stops to form said walls.  
   
   
       11 . The zipper of  claim 1  wherein said endstops are formed on top of said first profile.  
   
   
       12 . A zipper for a reclosable bag including: 
 a first profile;    a second profile;    a slider which, when moved in a first direction along said first and second profiles, separates said first profile from said second profile and, when moved in a second direction opposite to said first direction, interlocks said first profile to said second profile;    end stops formed from glue for restricting movement of said slider, said end stops having a wall facing said slider.    
   
   
       13 . The zipper of  claim 12  wherein each of said end stops is formed from a dot of hot glue.  
   
   
       14 . The zipper of  claim 13  wherein said end stops are formed proximate to ends of said first profile.  
   
   
       15 . The zipper of  claim 13  wherein said end stops are formed proximate to ends of said first profile and said second profile.  
   
   
       16 . The zipper of  claim 15  wherein said walls are formed by a reciprocating blunt end.  
   
   
       17 . The zipper of  claim 12  wherein said walls are formed by a blade.  
   
   
       18 . The zipper of  claim 12  wherein said walls are formed by a grinding element.  
   
   
       19 . The zipper of  claim 12  wherein a gas stream is impinged against said end stops to form said walls.  
   
   
       20 . The zipper of  claim 12  wherein said end stops are formed on top of said zipper.
