Sealable Bag

Abstract

A sealable plastic bag has a first panel and a second panel. The first and second panels are joined to each other along three edges to define a bag interior and an opening permitting access to the bag interior. A resealable sealing structure extends continuously between the first and second side edges of at least one of the panels and is configured to repeatedly and nondestructively seal and unseal the first and second panels to close and open the bag interior. A secondary sealing structure extends continuously between the first and second side edges of both of the panels below the resealable sealing structure but spaced toward the top edges of the panels. The secondary sealing structure is also configured to repeatedly and nondestructively seal and unseal the first and second panels together to close and open the bag interior.

What is claimed is: 
     
         1 . A plastic bag comprising:
 a first panel having a bottom edge, first and second side edges, and a top edge;   a second panel having a bottom edge, first and second side edges, and a top edge, the first and second panels being joined to each other along the respective bottom edges and first and second side edges to define a bag interior, the first and second panels defining an opening between the respective top edges permitting access to the bag interior;   a resealable sealing structure extending continuously between the first and second side edges of at least one of the panels generally adjacent to the top edges of the panels, the resealable sealing structure being configured to repeatedly and nondestructively seal the first and second panels together to prevent access to the bag interior; and   a secondary sealing structure extending continuously between the first and second side edges of both of the panels at a location closer to the bottom edge than the resealable sealing structure, the secondary sealing structure being spaced from the resealable sealing structure a distance less than a distance between the secondary sealing structure and the bottom edges of the first and second panels, the secondary sealing structure being configured to selectively seal the first and second panels together to prevent access to the bag interior.   
     
     
         2 . The plastic bag of  claim 1 , wherein the resealable sealing structure comprises a zipper structure. 
     
     
         3 . The plastic bag of  claim 1 , wherein the resealable sealing structure comprises adhesive. 
     
     
         4 . The plastic bag of  claim 1 , wherein the secondary sealing structure comprises a pair of cling film strips. 
     
     
         5 . The plastic bag of  claim 4 , wherein each of the pair of cling film strips comprises metallocene linear low-density polyethylene. 
     
     
         6 . The plastic bag of  claim 1 , wherein the resealable sealing structure is a different color than the first and second panels. 
     
     
         7 . The plastic bag of  claim 1 , wherein the secondary sealing structure is a different color than the first and second panels. 
     
     
         8 . The plastic bag of  claim 1 , wherein the secondary sealing structure is a different color than the resealable sealing structure. 
     
     
         9 . The plastic bag of  claim 1 , further comprising an extruded rib extending continuously between the first and second side edges of at least one of the panels at a location closer to the top edge than the resealable sealing structure. 
     
     
         10 . A plastic bag comprising:
 a first panel having a bottom edge, first and second side edges, and a top edge;   a second panel having a bottom edge, first and second side edges, and a top edge, the first and second panels being joined at the respective bottom edges and first and second side edges to define a bag interior, the first and second panels defining an opening between the respective top edges permitting access to the bag interior;   an interlocking sealing structure extending continuously between the first and second side edges of both of the panels generally adjacent to the top edges of the panels, the interlocking sealing structure being configured to repeatedly and nondestructively seal and unseal the first and second panels to close and open the bag interior;   a first cling film strip extending continuously between the first and second side edges of the first panel at a location closer to the bottom edge than the interlocking sealing structure, the first cling film strip being spaced from the interlocking sealing structure a distance less than a distance between the first cling film strip and the bottom edges of the first and second panels; and   a second cling film strip extending continuously between the first and second side edges of the second panel at a location closer to the bottom edge than the interlocking sealing structure, the second cling film strip being spaced from the interlocking sealing structure a distance less than a distance between the second cling film strip and the bottom edges of the first and second panels, the first and second cling film strips being adapted to repeatedly and nondestructively seal and unseal with each other to close and open the bag interior.   
     
     
         11 . The plastic bag of  claim 10 , wherein the first and second cling film strips comprise metallocene linear low-density polyethylene. 
     
     
         12 . The plastic bag of  claim 10 , wherein the interlocking sealing structure is a different color than the first and second panels. 
     
     
         13 . The plastic bag of  claim 12 , wherein the first and second cling film strips are a different color than the first and second panels. 
     
     
         14 . The plastic bag of  claim 10 , wherein the first and second cling film strips are a different color than the interlocking sealing structure. 
     
     
         15 . The plastic bag of  claim 10 , wherein the first cling film strip is a different color than the second cling film strip to provide visual indication to a user when the first and second cling film strips are engaged. 
     
     
         16 . The plastic bag of  claim 10 , further comprising an extruded rib extending continuously between the first and second side edges of at least one of the panels at a location closer to the top edge than the interlocking sealing structure. 
     
     
         17 . The plastic bag of  claim 10 , wherein the first cling film strip is co-extruded with the first panel and the second cling film strip is co-extruded with the second panel.
