Description

The present invention relates to a retort pouch food product in which a retort food product is hermetically sealed in a pouch for retort (hereinafter abbreviated as “pouch”) formed by laminating a synthetic resin film having flexibility.

Conventionally, a plastic tray device and a retort container (hereinafter referred to as “container”) formed by heat-sealing a plastic sheet-like lid material on an outward flange formed in the upper surface opening of the tray device. A retort container food in which retort food such as cooked rice is hermetically contained in this container is known (refer to Patent Document 1).

To eat this retort container food, put the whole container in boiling water before cooking or use a microwave oven to warm it, then peel off the sheet-like lid and open it before eating the retort food. Will do.
At this time, since the lowermost end of the tray device is formed on the flat bottom surface, when eating directly from the tray device, stability when placing the retort container food on a table or placing it on the palm is good .

However, after the meal, it is difficult to fold the tray device to make it smaller or to roll it down to make it smaller, so that it becomes bulky as garbage.

Conventionally, a retort pouch food in which a retort food is hermetically sealed in a standing pouch for retort (hereinafter abbreviated as “standing pouch”) formed by bonding a flexible synthetic resin film into a bag shape is known. (See Patent Document 2).

To eat this retort pouch food, put the standing pouch in hot water before cooking or use a microwave oven to warm it, then open the top of the standing pouch and open it before eating the retort food. Will do.

Since this standing pouch is formed by attaching a flexible synthetic resin film into a bag shape, after taking out the retort food inside, it can be folded down or rolled down to make it smaller. Therefore, there is an advantage that it is not bulky as garbage.

However, since the bottom heat seal surface formed on the outer periphery of the bottom surface of the standing pouch is formed in a downward flange shape, this bottom heat seal surface becomes the lowermost end of the standing pouch, creating a space below the bottom surface. End up.
In this way, the film-like thin heat-sealed surface protrudes downward from the bottom surface, so it is self-supporting when the retort pouch food is placed on the table or held by hand and eats directly from the standing pouch. There was a problem that it became insufficient or unstable, making it difficult to eat.

The bottom surface of the conventional standing pouch is not a flat bottom surface but a curved bottom surface protruding downward.
If formed on the curved bottom surface in this way, the height of the food contained inside will vary, and in particular, when heating associated with the retort treatment, heat is not evenly applied to the raw material, and overheating or heating There was a problem that heating unevenness such as lack was likely to occur.
