[0001] APPARATUS FOR MANUFACTURING A PACKING PAUCH FOR MICORWAVE COOKERY FOOD [0002]

The present invention relates to a device for manufacturing a pouch for heating cooked food, and more particularly, to a device for manufacturing a pouch for heating cooked food, and more particularly, The present invention relates to a device for manufacturing a pouch for a cooked food food having a steam discharging structure which is easy to manufacture and whose size can be easily controlled.

As is well known, a cooked or semi-cooked food or the like is filled in a packaging bag, a packaging pack, a packaging material (hereinafter referred to as a packaging pouch) made of a heat-resistant plastic film and sealed and heated by a microwave oven Packaged foods that can be cooked are on the market.

If such a packaged food for heating cooking is heated by a microwave oven, there is a problem that the internal pressure rises due to the steam generated in the inside of the packaging pouch and ruptures the packaging pouch to scatter the contents or contaminate the interior of the microwave oven. For example, scissors or the like have been used to drill a small vent hole or the like in a packaging pouch in advance, or to cut a part of the pouch to prevent the internal pressure from rising to prevent rupture of the pouch. However, There is a problem that the steam cooking effect by the steam is reduced and the food inside the pouch is dried and deteriorates the food.

Thus, a number of patent documents have been searched for in Patent Documents which allow a part of the packaging pouch to be heat sealed to be in a state of easy peeling, and to be able to discharge steam when the internal pressure rises.

However, in most conventional technologies having a steam discharging function, it is necessary to precisely adjust the bonding width and the bonding strength of some of the heat-sealed portions in the peelable state according to the cooking pressure. However, since this can not be controlled, There is a problem that the pouch is ruptured by the steam pressure, and the heat-sealed portion of the line contact is peeled off prematurely by heat-sealing a portion of the peelable portion through a mold or the like to a portion of the semi- The steam is rapidly discharged through the portion where the steam is quickly released, so that the hard contents such as sweet potatoes and the like are not cooked.
