Provided are a packaging container for a microwave oven that excels in the sealing performance between a container body and lid, and that at heating/cooking by a microwave oven, maintains the internal pressure of the container for a given period of time to thereby enhance the taste of contents through steaming effect, and that thereafter, can spontaneously open with certainty from a steam releasing seal part; and an efficient process for manufacturing the packaging container. In the packaging container for microwave oven having a lid heat-sealed to the periphery of a flange part of container body made of a synthetic resin so as to attain hermetic sealing, at least one steam releasing seal part with a weakened part is disposed inside the peripheral seal part of the flange part at a position separate from the peripheral seal part.

摘要:
A packaging container for cooking by an electronic oven having high sealability between a container body and a cover member and capable of being automatically and securely opened starting at a steam releasing seal part after taste of contents is improved by a steaming effect by holding a pressure in the packaging container for a specified time when the contents are heated and cooked by the electronic oven. The packaging container comprises a synthetic resin container body having a flange part and the cover member heat-sealed to the flange part of the container body. The cover member comprises (1) an upper member in which inner surfaces of resin films are positioned opposite to each other to form an abutted part, an unsealed part communicating with the inside of the container body is formed by heat-sealing a peripheral edge part of the abutted part excluding one side of the abutted part forming a base part, and the steam releasing seal part is formed at the abutted part and (2) a lower member which covers a lower surface of the upper member and in which a steam guide part communicating with the inside of the container body is formed at or near the base part of the abutted part.

It is known to apply a sealant to the inner surface of opening portions of a can end so as to reinforce the opening portions and to prevent the leakage of the contents. Devices were invented previously in order to achieve this purpose, but the efficiency of production with these devices is extremely low. The number of cans processed by such conventional devices is limited to about 75 per minute at most, and it is extremely difficult to raise the productivity beyond the limit. Because the sealant used is of very high viscosity, it is not easy to take out a small portion of it and coat it on the inside surface of the can end, and the operation is also time-consuming.The present invention has succeeded in taking out a small predetermined amount of such a high viscosity sealant always onto a stamping die, and this markedly increases the efficiency of production. While the conventional production results in the processing of about 75 pieces per minute, the present invention can increase it to about 300 per minute.

Provided is a package for cooking in a microwave oven, in which a synthetic resin container body having a flange part is filled with contents and a lid is heat-sealed to the flange part to seal the package hermetically. Independent concave parts sandwiching a heat-sealed part are provided in a part of the flange part on the inner and outer sides of the heat-sealed part to form, on the heat-sealed part, a projection part directed to the inner direction of the container and serving as a steam releasing part by automatically opening. The package is prevented from being broken or deformed by preventing the heat-sealed part from being peeled immediately after the contents are placed in the container body. When heating cooking is performed in a microwave oven, the package improves the taste of the contents by the steaming effect. The lid is sure to automatically open by the increase of the pressure in the container.

Stamping means in a single stroke initially passes upwardly through a pool of coating material to collect coating stuff on the face of the die element, then through a restricted opening formed integral with the coating material reservoir to remove excess coating stuff from the periphery of the die and finally into functional engagement with a substrate to simultaneously deform and coat the substrate.

An end face of an intermediate layer of a multilayer structure is stably covered by surface resin layers at a time of cutting the multilayer structure. A cutting method of the multilayer structure includes the steps of: compressing and deforming the multilayer structure, while extending respective layers of the multilayer structure to provide a thin thickness portion, so that an upper layer bites into a lower layer by pushing a push cutter, by a predetermined amount, into the multilayer structure supported by a cutter receiving portion, in a fused state of at least one of the resin layers forming the multilayer structure; and push-cutting the compressed thin thickness portion S till the push cutter abuts against the cutter receiving portion so as to converge an intermediate layer and surface resin layers of the multilayer structure to the abutting portion A of the push cutter and the cutter receiving portion.

There are disclosed a process and apparatus for producing sequentially a hermetically sealed container which comprise cutting a blank, forming a container body from the blank by a drawing method, filling a content in the container body and hermetically sealing the container body with a lid member, and devices for realizing these operations. The blank which is cut at a blanking station is placed on a movable die, and drawn to a container body at a drawing station. The container body engaged with the movable die is filled with a content at a filling station, and then hermetically sealed with a lid member at a sealing station. This process and apparatus are especially suitable for a blank made of a flexible material.
