Abstract

A reclosable bag having a bag interior and a bag opening, the bag interior comprising: a sealing section; an air-flow section configured to permit air flow through the air-flow section; and an air access interface positioned between the air-flow section and the sealing section, and configured to permit fluid communication therebetween; the bag further comprising: an openable closure configured and positioned to open and close the bag opening, the sealing section being positioned between the closure and the air-flow section; and a valve configured and positioned to permit air to be removed from the bag interior through the valve so as to create a negative pressure in the bag interior relative to an exterior of the bag; the sealing section being configured such that, when there is the negative pressure and the closure is closed, air is blocked from leaking from the exterior through the closure and sealing section to the air-flow section.

Claims

exact text as granted — not AI-modified
1 . A reclosable bag having a bag interior and a bag opening, the bag interior comprising: 
 (a) a sealing section;    (b) an air-flow section configured to permit air flow through said air-flow section; and    (c) an air access interface positioned between the air-flow section and the sealing section, and configured to permit fluid communication therebetween; 
 the bag further comprising:  
   (i) an openable closure configured and positioned to open and close the bag opening, the sealing section being positioned between the closure and the air-flow section; and    (ii) a valve configured and positioned to permit air to be removed from the bag interior through the valve so as to create a negative pressure in the bag interior relative to an exterior of the bag; 
 the sealing section being configured such that, when there is said negative pressure and the closure is closed, air is blocked from leaking from said exterior through said closure and sealing section to the air-flow section.  
   
     
     
         2 . The reclosable bag according to  claim 1 , 
 wherein said sealing section has a length comprising the minimum distance between said closure and said air-flow section,    and wherein said length is selected to prevent air flow from said exterior through said closure and sealing section to said air-flow section when said closure is closed and said bag interior has a negative air pressure.    
     
     
         3 . The reclosable bag according to  claim 2 , wherein said length of said sealing section is at least 1⅛ inches.  
     
     
         4 . The reclosable bag according to  claim 2 , wherein said length of said sealing section is at least 1¼ inches.  
     
     
         5 . The reclosable bag according to  claim 2 , wherein said length of said sealing section is at least 1½ inches.  
     
     
         6 . The reclosable bag according to  claim 2 , wherein said length of said sealing section is at least 1¾ inches.  
     
     
         7 . The reclosable bag according to  claim 2 , wherein said length of said sealing section is at least 2 inches.  
     
     
         8 . The reclosable bag according to  claim 2 , wherein said length of said sealing section is at least 2¼ inches.  
     
     
         9 . The reclosable bag according to  claim 2 , wherein said length of said sealing section is at least 2½ inches.  
     
     
         10 . The reclosable bag according to  claim 2 , wherein said length of said sealing section is at least 2¾ inches.  
     
     
         11 . The reclosable bag according to  claim 2 , wherein said length of said sealing section is at least 3 inches.  
     
     
         12 . The reclosable bag according to  claim 2 , wherein said length of said sealing section is at least 3¼ inches.  
     
     
         13 . The reclosable bag according to  claim 1 , wherein said sealing section comprises opposing panes closed along at least one side, and said valve is positioned between said panes on said at least one closed side.  
     
     
         14 . The reclosable bag according to  claim 13 , wherein said valve is positioned in fluid communication with said sealing section adjacent to said air access interface.  
     
     
         15 . The reclosable bag according to  claim 14 , wherein said valve is positioned within ½ inch of said air access interface.  
     
     
         16 . The reclosable bag according to  claim 1 , wherein said air-flow section is defined by opposing air-flow panes sized and shaped so that when said air-flow panes are in contact, channels are available to permit air flow through said air-flow section.  
     
     
         17 . The reclosable bag according to  claim 16 , wherein at least one of said panes has a surface defining one or more raised ribs.  
     
     
         18 . The reclosable bag according to  claim 17 , wherein said air-flow section comprises a ribbed pane and an opposing flat pane.  
     
     
         19 . The reclosable bag according to  claim 16 , wherein said air-flow section comprises opposing rectangular panes, said opposing panes being closed on three sides and open on one side, said open side comprising said air access interface.  
     
     
         20 . The reclosable bag according to  claim 1 , wherein said sealing section comprises opposing sealing section panes sized and shaped so that when said panes are in contact, passage of air through said sealing section is blocked.  
     
     
         21 . The reclosable bag according to  claim 20 , wherein said opposing panes each have a flat surface.  
     
     
         22 . The reclosable bag according to  claim 20 , wherein said sealing section comprises opposing rectangular panes, said opposing panes being open on two opposing sides and closed on another two opposing sides, wherein one of said open sides is attached to said air access interface and the other of said open sides defines said bag opening.  
     
     
         23 . The reclosable bag according to  claim 1 , wherein said closure comprises a zipper having opposed interlocking features, and said zipper is attached to said sealing section at said opposing end of said sealing section.  
     
     
         24 . The reclosable bag according to  claim 1 , wherein said closure comprises a zipper having opposed interlocking features, and said zipper further includes an extended portion comprising said sealing section.
