Abstract

A container for food includes a bottom portion having a circular shape; a wall portion including a first wall portion formed continuously from the bottom portion and formed with a curved surface and an inclined surface inclined relative to the bottom portion, and a second wall portion formed continuously from the first wall portion and extending in a direction orthogonal to a surface direction of the bottom portion, the wall portion including an opening formed in a rectangular shape on one side and in a semielliptical shape on another side; and a flange portion formed continuously from the second wall portion.

What is claimed is: 
     
         1 . A container for food, comprising:
 a bottom portion having a circular shape;   a wall portion including a first wall portion formed continuously from the bottom portion and formed with a curved surface and an inclined surface inclined relative to the bottom portion, and a second wall portion formed continuously from the first wall portion and including at least a surface extending in a direction orthogonal to a surface direction of the bottom portion, the wall portion including an opening formed in a rectangular shape on one side and in a semielliptical shape on another side; and   a flange portion formed continuously from the second wall portion.   
     
     
         2 . The container for food according to  claim 1 , wherein the first wall portion on the rectangular shape side forms a gentler inclined angle relative to the bottom portion than that of the first wall portion on the semielliptical shape side. 
     
     
         3 . The container for food according to  claim 1 , wherein the second wall portion includes a first surface portion formed at upper end of the first wall portion and extending in the surface direction of the bottom portion, and a second surface portion extending in a direction orthogonal to the surface direction of the bottom portion and including an upper end at which the flange portion is formed; and
 the flange portion extends in the surface direction of the bottom portion.   
     
     
         4 . The container for food according to  claim 1 , further comprising a lid fixed to the flange portion and sealing the opening of the wall portion. 
     
     
         5 . The container for food according to  claim 2 , further comprising a lid fixed to the flange portion and sealing the opening of the wall portion. 
     
     
         6 . The container for food according to  claim 3 , further comprising a lid fixed to the flange portion and sealing the opening of the wall portion.
