Abstract
The present disclosure relates to a container for retort food and, more specifically, to a container for retort food, which includes: a ridge portion having a closed curve shape to surround a tray part; and an exhaust hole surrounded by the ridge portion, so that the container enables a lid film to be automatically peeled off from the ridge portion by means of a steam pressure generated in a food during heating to exhaust steam and can be used for retort food which is stored at room temperature.
Claims4
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.
