Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a container used for the production of heat-coagulable foods such as custard pudding and chawanmushi.

2. Description of the Related Art Conventionally, a container in which a food material is stored is stored in a tank, and a container for producing a heat-coagulable food by heating under pressure or cooling under reduced pressure does not have a lid at all or the entire opening is covered. What was covered with was used.

Problems to be solved by the invention If the container is processed without a lid, condensed water in the tank may fall into the container during cooling and the quality may deteriorate. If the temperature rises, the water vaporizes inside the container and the pressure inside the container also rises.However, the water vaporized inside the container condenses and drops during the cooling process, and it deforms depending on the strength of the container. There was a problem.

Means for Solving the Problems The container for thermocoagulable food according to the present invention is provided with a lid at the opening of the cup containing the material utilization, and the edge of the cup opening end is inserted and fitted around the outer periphery of the lid. In addition to the provision, a ventilation small hole is provided in the center of the lid, and an edge portion that is integral with the lid and is inclined downward in the outer peripheral direction is integrally formed with the lid at the peripheral portion of the small hole.

Action Put food material in a container with a small hole in the center of the lid as described above, and in the case of processing in the tank, first, when the temperature is raised by heating, the temperature inside the container as well as the inside of the container rises, and vapor from the food forms an air layer It rises and is discharged from the small hole in the center of the lid to the outside of the container, and the lid does not swell due to the pressure increase in the container. Further, it is possible to prevent dew condensation from dropping into food even when it is cooled under reduced pressure. By providing a small hole, it is possible to reduce the pressure difference between the inside and the outside of the container during cooling, and the small hole in the center of the lid has an edge portion that is inclined downward to the outer peripheral direction at the peripheral edge, so that the water condensed in the tank can be prevented. Even if it falls onto the container, it will flow along the inclined edge along the outer surface of the lid and will not enter the container.

Example 1 is a heat-resistant cup containing food 2, 3 is a plastic lid of cup 1, and has an edge 4 into which the open end of cup 1 is inserted and fitted. Reference numeral 5 denotes a ventilation small hole provided at the center of the lid 3, and an edge portion which is inclined downward in the outer peripheral direction is integrally formed on the peripheral edge of the small hole 5 on the upper surface side of the lid 3.
There is an air layer between the surface of the food 2 and the lid.

FIG. 2 shows a state in which a heat-coagulable food is manufactured using the container according to the present invention. A plurality of containers containing food are placed on the tray 6, and the plurality of trays 6 are placed on the carriage 7. It is built in the tank 8.

The cup is not limited to glass and may be one having heat resistance such as plastic or ceramic, and the lid may be formed of a light metal alloy such as stainless steel or aluminum, or a film.

When the pressure inside the tank 8 is increased, the temperature inside the cup 1 is also increased.
Steam vaporized from the food is discharged from the small hole 5 of the lid 3 to the outside of the cup 1. Therefore, the wall surface of the cup 1 and the lid 3 are not expanded during the heat treatment. Heat treatment is completed,
When cooling under reduced pressure, the lid 3 has a small hole, so that a vacuum phenomenon does not occur in the cup, and moreover, even if the dew condensation generated in the tank by cooling under reduced pressure drops onto the food container, Since the peripheral edge of the small hole 5 is inclined toward the outer peripheral direction, there is no possibility that dew condensation water flows on the upper surface of the lid and enters the cup. Further, since the pressure difference between the tank and the cup during food processing is small, it is possible to prevent deformation of the container and adsorption of the food surface and the lid during cooling.

After completion of food processing, the lid with small holes is often replaced with a lid such as a lid with a heat-shrinkable film for shipping and distribution, and after storage and management under certain conditions such as a refrigerator, after food processing The lid may not be replaced.

EFFECTS OF THE INVENTION Since the present invention has the above-described structure and operation, it is possible to prevent the quality of food from deteriorating without dropping water droplets and bubbles on the food and to obtain a product with a smooth and smooth surface. By providing a small hole in the lid, the pressure difference between the inside of the tank and the inside of the container during heating and cooling can be reduced, so the lid may be adsorbed on the food surface when the pressure inside the container changes. It is possible to prevent the container from being deformed.
