Sealable product containment bag

Abstract

A sealable product containment bag structure is described that includes generally rectangular shaped front and rear panels and pleated generally rectangular side panels connected to the front and rear panels, the front, rear and side panels forming at one end thereof an open top for the bag structure and being folded together at the other end thereof to form a closed bottom. In one embodiment of the invention, adhesive strips are disposed in confronting relationship to each other on the inner surfaces of the front and rear panels near the open top end of the bag whereby the adhesive strips adhere to each other and to the inner surfaces of the side panels when the side panels are folded inwardly in a closed condition for the bag structure.

       8 . A sealable product containment bag structure comprising:
 (a) generally rectangular confronting front and rear panels, each of said front panel and said rear panel having an inner surface and an outer surface;   (b) pleated generally rectangular side panels interconnecting said front and rear panels, each of said side panels having an inner surface and an outer surface, said inner surfaces of said front, rear and side panels defining a generally rectangular volumetric shape;   (c) said front, rear and said side panels defining a top opening for the bag structure at a first end of said panels, said front, rear and side panels folded together at a second end of said panels to form a closed bottom for the bag structure;   (d) each of said side panels having pleats whereby said side panels are foldable inwardly between said front and rear panels in a closed condition for the bag structure;   (e) each of said front and rear panels including a marginal extension in the form of a closure flap at said first ends of said front and rear panels; and   (f) an adhesive strip disposed on the inner surface of at least one of said closure flaps along the width of said opening and in confronting relationship with the inner surface of the other said closure flap, whereby said closure flaps adhere to each other in said closed condition.   
   
   
       9 . The bag structure of  claim 8  wherein said adhesive strips comprise a pressure sensitive adhesive. 
   
   
       10 . The bag structure of  claim 9  wherein the said adhesive is selected to render said adhesive strips resealable. 
   
   
       11 . The bag structure of  claim 8  wherein said front, rear and side panels comprise a material selected from the group consisting of paper, cloth fabric and plastic. 
   
   
       12 . The bag structure of  claim 11  wherein said material is insulated. 
   
   
       13 . The bag structure of  claim 8  further comprising a handle attached to each of said front and rear panels. 
   
   
       14 . The bag structure of  claim 8  wherein front, rear and side panels are adhesively joined at said second ends of said panels to form said closed bottom for the bag structure. 
   
   
       15 . A sealable product containment bag structure comprising:
 (a) generally rectangular confronting front and rear panels, each of said front panel and said rear panel having an inner surface and an outer surface;   (b) pleated generally rectangular side panels interconnecting said front and rear panels, each of said side panels having an inner surface and an outer surface, said inner surfaces of said front, rear and side panels defining a generally rectangular volumetric shape;   (c) said front, rear and said side panels defining a top opening for the bag structure at a first end of said panels, said front, rear and side panels folded together at a second end of said panels to form a closed bottom for the bag structure;   (d) each of said side panels having pleats whereby said side panels are foldable inwardly between said front and rear panels in a closed condition for the bag structure;   (e) one of said front and rear panels including a marginal extension in the form of a closure flap at said first end of said one of said front and rear panels; and   (f) an adhesive strip disposed on the inner surface of said closure flap along the width of said opening, said closure flap foldable over said opening and sealable to the outer surface of the other of said front and rear panels in said closed condition.
