Configuring bag closures

Abstract

A reclosable bag has a body with opposite faces having side edges and defining an interior. The bag also has a reclosable hook-and-loop fastener strip secured to one of the bag faces. The fastener strip may form a reclosable face closure for accessing the bag interior through a face of the bag. In some cases the closure strip extends around one or more of the edges of the bag to form a pour spout side opening or to define a hinge as in a flip top box.

What is claimed is:  
     
         1 . A bag having a body with opposite faces having side edges and defining an interior, the bag comprising 
 a reclosable fastener strip secured to one of the bag faces and extending around one of the edges of the bag to form a reclosable bag closure for accessing the bag interior.    
     
     
         2 . The bag of  claim 1  wherein the fastener strip is secured to an inside surface of the bag.  
     
     
         3 . The bag of  claim 2  wherein the bag body has a frangible tear line for accessing the fastener strip.  
     
     
         4 . The bag of  claim 1  wherein the fastener strip includes a loop component with a band of hook-engageable loops, and a mating hook component with a band of hooks.  
     
     
         5 . The bag of  claim 4  wherein the hooks are integrally molded along an edge of the hook component.  
     
     
         6 . The bag of  claim 1  wherein the fastener strip comprises two mating components, both secured to an inside surface of a face of the bag.  
     
     
         7 . The bag of  claim 1  wherein the bag body comprises film, and wherein the fastener strip is welded to the film.  
     
     
         8 . The bag of  claim 1  wherein the fastener strip extends across an entire front face of the bag and around opposite edges of the bag.  
     
     
         9 . The bag of  claim 1  wherein the closure extends from a front face of the bag around one side edge of the bag to a back face of the bag to form a pour spout for pouring bag contents from a bag opening at the edge of the bag.  
     
     
         10 . The bag of any of  claim 1  wherein ends of the closure are loose from each other.  
     
     
         11 . A method of making a reclosable bag having a body with opposite faces having side edges and defining an interior, the method comprising forming the bag on a bag making machine from a roll of film having pre-applied closure strips arranged so as to extend around one of the edges of the bag to form a reclosable bag closure for accessing the bag interior.  
     
     
         12 . The method of  claim 11  wherein the fastener strip is secured to an inside surface of the bag.  
     
     
         13 . The method of  claim 12  wherein the bag body has a frangible tear line for accessing the fastener strip.  
     
     
         14 . The method of  claim 1  wherein the fastener strip includes a loop component with a band of hook-engageable loops, and a mating hook component with a band of hooks.  
     
     
         15 . The method of  claim 14  wherein the hooks are integrally molded along an edge of the hook component.  
     
     
         16 . The method of  claim 11  wherein the fastener strip comprises two mating components, both secured to an inside surface of a face of the bag.  
     
     
         17 . The method of  claim 11  wherein the bag body comprises film, and wherein the fastener strip is welded to the film.  
     
     
         18 . The method of  claim 11  wherein the fastener strip extends across an entire front face of the bag and around opposite edges of the bag.  
     
     
         19 . The method of  claim 11  wherein the closure extends from a front face of the bag around one side edge of the bag to a back face of the bag to form a pour spout for pouring bag contents from a bag opening at the edge of the bag.  
     
     
         20 . The method of  claim 11  wherein ends of the closure are loose from each other.  
     
     
         21 . A bag having a body with opposite faces having side edges and defining an interior, the bag comprising a reclosable fastener strip secured to the bag body and arranged to form a reclosable face closure for accessing the bag interior through a face of the bag, the fastener strip including a loop component with a band of hook-engageable loops, and a mating hook component with a band of hooks.  
     
     
         22 . The bag of  claim 21  wherein the fastener strip is secured to an inside surface of a front face of the bag.  
     
     
         23 . The bag of  claim 22  wherein the bag body has a frangible tear line for accessing the fastener strip.  
     
     
         24 . The bag of  claim 21  wherein the hooks are integrally molded along an edge of the hook component.  
     
     
         25 . The bag of  claim 21  wherein the bag body comprises film, and wherein the fastener strip is welded to the film.  
     
     
         26 . A method of making a reclosable bag having a body with opposite faces having side edges and defining an interior, the method comprising forming the bag on a bag making machine from a roll of film having a pre-applied closure strip arranged to form a reclosable face closure for accessing the bag interior through a face of the formed bag, the fastener strip including a loop component with a band of hook-engageable loops, and a mating hook component with a band of hooks.
