Water-tight zipper with two slides

Abstract

A water-tight zipper ( 2 ) has two slides ( 7, 8 ) and comprises two halves, each half comprising a zipper ribbon and zipper teeth which can be closed or separated by means of the slides. In the closed state of the zipper, the slides ( 7, 8 ) are sealingly arranged next to one another or lie next to one or more at least in part common sealing elements.

1 . A water-tight zipper ( 2 ) with two sliders ( 7 ,  8 ) consisting of two zipper halves that are each formed from a strip of tape and from teeth and are closed or separated by means of said sliders, characterized in that, in the closed condition of the zipper, said sliders ( 7 ,  8 ) fit sealingly against each other or against one or a plurality of sealing elements that are at least in parts common to both.  
   
   
       2 . The water-tight zipper as set forth in  claim 1 , characterized in that the two zipper halves comprise one or a plurality of sealing elements that are each solidly connected therewith.  
   
   
       3 . The water-tight zipper as set forth in  claim 2 , characterized in that the sealing element or elements comprise one or a plurality of sealing lips.  
   
   
       4 . The water-tight zipper as set forth in  claim 3 , characterized in that the sealing lip or lips are arranged parallel to the surface of the strips of tape and transverse to the longitudinal axis of the zipper.  
   
   
       5 . The water-tight zipper as set forth in  claim 3 , characterized in that the sealing lip or lips are connected to sealing lips of the zipper.  
   
   
       6 . The water-tight zipper as set forth in  claim 5 , characterized in that the sliders apply a pressure from the side and/or from the top to the sealing lips of the zipper in the region of their connection with the sealing lip or lips in the closed condition.  
   
   
       7 . The water-tight zipper as set forth  claim 1 , characterized in that, in the closed condition of the zipper, a sealing contact point ( 6 ) is interposed between the sliders ( 7 ,  8 ).  
   
   
       8 . The water-tight zipper as set forth in  claim 7 , characterized in that the sealing lips of the zipper are connected to the contact point ( 6 ).  
   
   
       9 . The water-tight zipper as set forth in  claim 7 , characterized in that, in the closed condition of the zipper, the sliders ( 7 ,  8 ) are clampingly engaged with the contact point.  
   
   
       10 . The water-tight zipper as set forth in  claim 7 , characterized in that the contact point ( 6 ) forms a raised portion.  
   
   
       11 . The water-tight zipper as set forth in  claim 10 , characterized in that the sliders ( 7 ,  8 ) comprise a contour ( 12 ) conforming to the raised portion, said contour being clamped or pressed to fit against said raised portion in the closed condition of the zipper.  
   
   
       12 . The water-tight zipper as set forth in  claim 1 , characterized in that a blocking device is provided for the closure position of the sliders.  
   
   
       13 . The water-tight zipper as set forth in  claim 12 , characterized in that the blocking device is a securing pin, a lock or a screw closure.  
   
   
       14 . The water-tight zipper as set forth in  claim 12 , characterized in that the blocking device consists of eccentric levers.  
   
   
       15 . The water-tight zipper as set forth in  claim 12 , characterized in that the blocking device is integrated into, or integral with, the pullers of the sliders.  
   
   
       16 . The water-tight zipper as set forth in  claim 1 , characterized in that the sealing element or elements are injection moulded or vulcanized thereon.  
   
   
       17 . The water-tight zipper as set forth in  claim 1 , characterized in that the strips of tape are joined together in the sealing region between the sliders.  
   
   
       18 . The water-tight zipper as set forth in  claim 17 , characterized in that the connection is obtained by welding.  
   
   
       19 . The water-tight zipper as set forth in  claim 17 , characterized in that the ends of the zipper halves are welded together with a cut piece of water-tight fabric ( 3 ).  
   
   
       20 . The water-tight zipper as set forth in  claim 1 , characterized in that the zipper is configured to be a ring closure.  
   
   
       21 . The water-tight zipper as set forth in  claim 1 , characterized in that there is provided at least one stopper device for the sliders.  
   
   
       22 . The water-tight zipper as set forth in  claim 21 , characterized in that the stopper device is sealingly disposed in a notch provided in the strips of tape.  
   
   
       23 . The water-tight zipper as set forth in  claim 22 , characterized in that the stopper device is disposed in the notch so as to be releasable through screwing or the like.  
   
   
       24 . The water-tight zipper as set forth in  claim 22 , characterized in that the notch serves for introducing the sliders.  
   
   
       25 . A container, bag or suitcase with a surrounding water-tight zipper as defined in  claim 1.
