Pouch for food

Abstract

The present disclosure relates to a pouch for food. More particularly, it relates to a pouch for food, which is used to heat food by placing it in a microwave oven while storing the food and can properly exhaust vapor generated during the cooking process, thereby improving the texture and taste of food and reducing the manufacturing cost.

1 . A pouch for food, which comprises a sheet forming an inner space with its edges fused; a perforated line formed on the sheet; a first exhaust unit positioned in a central region of the sheet and comprising a plurality of first exhaust holes; and a second exhaust unit positioned in a peripheral region of the sheet as spaced apart from the first exhaust unit and comprising a plurality of second exhaust holes, wherein the plurality of second exhaust holes are arranged perpendicular to the perforated line. 
     
     
         2 . The pouch for food of  claim 1 , wherein the first exhaust holes and the second exhaust holes are each holes that pass through the sheet. 
     
     
         3 . The pouch for food of  claim 1 , wherein the first exhaust holes are arranged in a direction parallel to the perforated line and a direction perpendicular to the perforated line, respectively. 
     
     
         4 . The pouch for food of  claim 3 , wherein the number of the first exhaust holes arranged in the direction perpendicular to the perforated line is greater than the number of the first exhaust holes arranged in the direction parallel to the perforated line. 
     
     
         5 . The pouch for food of  claim 1 , wherein the number of the first exhaust holes is 6 to 9. 
     
     
         6 . The pouch for food of  claim 1 , wherein the second exhaust unit is positioned on the left and right sides of the first exhaust unit, respectively. 
     
     
         7 . The pouch for food of  claim 6 , wherein the second exhaust unit positioned on the left side of the first exhaust unit and the second exhaust unit positioned on the right side comprise the same number of the second exhaust holes. 
     
     
         8 . The pouch for food of  claim 1 , wherein the total number of the plurality of second exhaust holes is 12 to 14. 
     
     
         9 . The pouch for food of  claim 1 , wherein the total number of the plurality of first exhaust holes and the plurality of second exhaust holes is 20 to 22. 
     
     
         10 . The pouch for food of  claim 1 , wherein the sheet does not comprise other penetrating holes than the first exhaust holes and the second exhaust holes. 
     
     
         11 . The pouch for food of  claim 1 , wherein the first exhaust holes are formed on the front side of the pouch for food, and the second exhaust holes are formed on the rear side of the pouch for food. 
     
     
         12 . The pouch for food of  claim 1 , wherein the number of the plurality of first exhaust holes is smaller than the number of the plurality of second exhaust holes. 
     
     
         13 . The pouch for food of  claim 1 , wherein the first exhaust holes and the second exhaust holes have sizes different from each other. 
     
     
         14 . The pouch for food of  claim 1 , wherein the width of the second exhaust hole is greater than the width of the first exhaust hole. 
     
     
         15 . The pouch for food of  claim 14 , wherein the ratio of the width of the second exhaust hole to the width of the first exhaust hole is 1.3 to 2.5. 
     
     
         16 . The pouch for food of  claim 1 , wherein the spacing between the plurality of second exhaust holes is greater than the spacing between the plurality of first exhaust holes. 
     
     
         17 . The pouch for food of  claim 1 , wherein the depth of the perforated line is 8 μm to 10 μm. 
     
     
         18 . The pouch for food of  claim 1 , wherein the tensile strength at break of the perforated line is 30 N to 50 N. 
     
     
         19 . The pouch for food of  claim 1 , wherein the sheet has a laminated structure of a polyethylene film and a polyethylene terephthalate film. 
     
     
         20 . The pouch for food of  claim 19 , wherein the polyethylene film is positioned adjacent to the inner space, and the perforated line is formed only on the polyethylene terephthalate film.
