Film bag

Abstract

A film bag has a front and back panel and an inner cover patch therebetween. A continuous frame weld secures the inner cover patch to the inner face of the front panel. A first cut or weakening line in the front panel within an area bounded by the frame weld defines all but one side of a flap hinged at the one side to the front panel. A reclosable fastener is between the front face of the patch and the inner face of front panel, and a direct attachment between the fastener and the hinge is between the front face of the flap to the inner face of the front panel. A second cut or weakening line is formed in the inner cover patch between the direct attachment to the flap and the recloseable fastener.

What is claimed is: 
     
         1 . A film bag comprising:
 a front panel and a back panel having confronting inner faces and outer face forming an outer surface of the film bag;   an inner cover patch between the front and back panels and having a front face confronting the back face of the front panel;   a continuous frame weld securing the inner cover patch to the inner face of the front panel;   a first cut or weakening line in the front panel within an area bounded by the frame weld defining all but one side of a flap connected unitarily as a hinge at the one side to the front panel;   a reclosable fastener between the front face of the patch and the inner face of front panel;   a direct attachment between the fastener and the hinge directly connecting the front face of the flap to the inner face of the front panel; and   a second cut or weakening line formed in the inner cover patch between the direct attachment to the flap and the recloseable fastener, whereby outward pivoting of the flap of the front panel about the hinge separates the reclosable fastener and pulls out a portion of the patch between the second line and the attachment.   
     
     
         2 . The film bag defined in  claim 1 , wherein the reclosable fastener is formed by a hook and loop fastener. 
     
     
         3 . The film bag defined in  claim 1 , wherein the reclosable fastener is formed by interlocking profile strips. 
     
     
         4 . The film bag defined in  claim 1 , wherein the reclosable fastener is a strip fastener extending between opposite sides of the flap. 
     
     
         5 . The film bag defined in  claim 1 , wherein the front panel and the back panel have weldable inner faces and that the bag is held together by thermal welds. 
     
     
         6 . The film bag defined in  claim 5 , wherein the front face of the inner cover patch is weldable and the frame weld or the direct attachment between flap and inner cover patch are formed thermally. 
     
     
         7 . The film bag defined in  claim 1 , wherein the frame weld or the direct attachment between the flap and the inner cover patch are formed by an adhesive. 
     
     
         8 . The film bag defined in  claim 1 , further comprising:
 side gussets provided between the front panel and the back panel.   
     
     
         9 . The film bag defined in  claim 1 , wherein the flap has a grip tab at a side opposite the one side of the hinge. 
     
     
         10 . The film bag defined in  claim 9 , wherein the grip tab of the flap is defined by a full cut whereas the rest of the flap is defined by a weakening line. 
     
     
         11 . The film bag defined in  claim 1 , wherein at least one of the weakening lines is formed by a perforation, a score or a laser score. 
     
     
         12 . The film bag defined in  claim 1 , wherein the second cut or weakening line provided on the inner cover patch forms an inner flap surrounding the direct attachment and offset inwardly from the frame weld.
