OG exemplary drawing
 
1. A container for retort food, the container comprising:
a tray part which has a predetermined area and a depth recessed in a downward direction and has a space open in an upward direction; and
a flange part which constitutes a periphery of an upper end of the tray part, wherein the flange part comprises
an outer flange area which constitutes an outer circumference of the container for retort food and
an inner flange area which divides the tray part across the container for retort food,
wherein the flange part comprises:
a ridge portion which is formed on the flange part, has a closed curve shape to surround the tray part, and protrudes in the upward direction; and
an exhaust hole which vertically passes through at least a portion of the flange part,
wherein the ridge portion comprises
an inner ridge formed on the inner flange area and
an outer ridge formed on the outer flange area and branching from the inner ridge,
wherein the exhaust hole is located in the inner flange area,
the inner ridge
has a branch ridge having a closed curve shape that branches with the exhaust hole therebetween, and
the exhaust hole is located within the closed curve shape formed by the branch ridge and an intermediate ridge which connects the branch ridge and the outer ridge, wherein the intermediate ridge comprises a first intermediate line and a second intermediate line which are disposed with the branch ridge therebetween and are respectively located on opposing sides of the branch ridge, and the branch ridge comprises a first branch line and a second branch line which are spaced apart from each other in a horizontal direction, wherein the first branch line and the second branch line have one end connected to an end of the first intermediate line and the other end connected to an end of the second intermediate line,
the first branch line and the second branch line form a closed curve shape and the exhaust hole is located in the closed curve shape, and
at least one of the first branch line and the second branch line comprises a first tip end protruding toward the tray part, wherein a radius of curvature of the intermediate ridge is greater than a radius of curvature of the outer ridge.
