Zip lock closure

Abstract

A one-way, zip-locking closure for bag-type containers that include slider zipper arrangements. The locking mechanism includes a series of registration structures that is provided along one side of the mouth of the containers and a catch mechanism that is provided within the slider. The catch mechanism engages the series of registration structures as the slider is moved to close the mouth of the container, and thereby prevents movement of the slider in the opposite direction.

1 - 15 . (canceled)  
   
   
       16 . A bag-type container having a mouth defined by opposed side panels, said bag-type container comprising: 
 cooperating coupling structures on inner surfaces of the opposed side panels adjacent the mouth;    a slider coupled to the cooperating coupling structures for closing the mouth of the bag-type containing when slid in a first direction between a first position to a second position; and    a series of projecting structures provided along at least one side of the bag-type container near the mouth and spaced away from an upper top edge of the bag-type container.    
   
   
       17 . A bag-type container according to  claim 16 , wherein a series of projecting structures is spaced away from a top edge of the cooperating coupling structures.  
   
   
       18 . A bag-type container according to  claim 16 , wherein a series of projecting structures is provided along both sides of the bag-type container near the mouth.  
   
   
       19 . A bag-type container according to  claim 16 , wherein the projecting structures are substantially parallel to one another and to side edges of the bag-type container.  
   
   
       20 . A bag-type container according to  claim 17 , wherein the projecting structures are substantially parallel to one another and to side edges of the bag-type container.  
   
   
       21 . A bag-type container according to  claim 16 , wherein the series of projecting structures extend across the entire width of the bag-type container.  
   
   
       22 . A bag-type container according to claim  1   16 , wherein the slider extends over the series of projecting structures.  
   
   
       23 . A bag-type container according to  claim 16 , wherein the slider is provided with a structure that abuts the series of projecting structures.
