Storage bag

Abstract

A storage bag comprises a bag body including a first sheet and a second sheet attached to the first sheet to have an internal empty space, lips formed along an upper edge of the bag body, a fastener formed in the lips to open or close the internal empty space, and an air exhaustion means opening or closing an opening formed in at least one of the first sheet or the second sheet.

What is claimed is: 
     
         1 . A zipper bag, comprising:
 a first sheet and a second sheet attached at lower ends and two opposite side ends thereof, with an inlet formed at upper ends of the first sheet and the second sheet;   zipper sheets respectively attached onto inner surfaces of the upper ends of the first sheet and the second sheet; and   zippers respectively attached onto the zipper sheets to be fastened or unfastened, wherein an air exhausting means is formed in a surface of at least one of the first sheet and the second sheet to exhaust air from an inside of the zipper bag between the first sheet and the second sheet to an outside with the inside of the zipper bag sealed up.   
     
     
         2 . The zipper bag of  claim 1 , wherein the air exhaustion hole means includes:
 an air exhaustion hole formed in at least one sheet of the first sheet and the second sheet;   a first sheet zipper formed around the air exhaustion hole on an inner surface of the at least one sheet;   a second sheet zipper formed on an inner surface of the opposite sheet of the at least one sheet.   
     
     
         3 . The zipper bag of  claim 1 , wherein the air exhausting means includes:
 an air exhaustion hole formed in a surface of at least one of the first sheet and the second sheet;   a first zipper projecting from the surface around the air exhaustion hole; and   an air lock sheet including a second zipper that may be fastened onto or unfastened from the first zipper on an internal circumferential surface of the air lock sheet.   
     
     
         4 . The zipper bag of  claim 1 , wherein the air exhausting means is formed at an upper and right or left portion of the surface of at least one of the first sheet and the second sheet. 
     
     
         5 . The zipper bag of  claim 3 , wherein the first zipper and the second zipper are formed in two or more rows with a predetermined interval therebetween. 
     
     
         6 . The zipper bag of  claim 1 , wherein the air exhausting means is shaped as a circle or a polygon. 
     
     
         7 . The zipper bag of  claim 1 , wherein the air exhausting means includes an air exhaustion valve, and wherein the air exhaustion valve includes:
 a thermal fusion plate having an air exhaustion hole at a center thereof and attached onto a surface of at least one of the first sheet or the second sheet, an anti-stick part projecting from a surface of the thermal fusion plate to prevent the first sheet and the second sheet from sticking together upon air exhaustion, and a vacuum sucking part projecting to communicate with the air exhaustion hole on an opposite surface of the thermal fusion plate;   a packing inserted into the air exhaustion hole; and   a sealing member opening and closing the vacuum sucking part and including a coupling ring fitted over an outer circumferential surface of the vacuum sucking part to tightly contact the thermal fusion plate and a lower surface of a thermally fused portion of the first sheet, a lead inserted onto an inner circumferential surface of the vacuum sucking part, and a connecting band connecting the coupling ring with the lead.   
     
     
         8 . The zipper bag of  claim 7 , wherein the inner circumferential surface of the vacuum sucking part includes a first surface whose inner diameter decreases to the air exhaustion hole and a second surface connected with the first surface and having a constant inner diameter. 
     
     
         9 . The zipper bag of  claim 7 , wherein the packing includes:
 a tight seal plate covering an upper portion of the air exhaustion hole;   a jaw fastened to a lower portion of the air exhaustion hole; and   a connecting body connecting the tight seal plate with the jaw and inserted into the air exhaustion hole.   
     
     
         10 . A storage bag, comprising:
 a bag body including a first sheet and a second sheet attached to the first sheet to have an internal empty space, lips formed along an upper edge of the bag body;   a fastener formed in the lips to open or close the internal empty space; and   an air exhaustion means opening or closing an opening formed in at least one of the first sheet or the second sheet.   
     
     
         11 . The storage bag of  claim 10 , wherein the air exhaustion means includes a first engaging part formed around the opening and a cap including a second engaging part to open or close the opening, and wherein the first engaging part and the second engaging part fit together to close the opening. 
     
     
         12 . The storage bag of  claim 10 , wherein the air exhaustion means includes a first coupling member and a second coupling member with the opening disposed therebetween, and wherein the first coupling member includes a cap configured to detachably couple with the second coupling member to close the opening.
