調理用密封容器に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sealed container for food, and more particularly to a sealed container for microwave cooking that opens automatically when heated in a microwave oven. It is something.
昨今、手間がかからないことなどから容器のまま電子レ

すようにしたものである。However, if the food was heated in a microwave oven without opening the lid, the pressure inside the container would increase and the container would burst, causing the food to scatter inside the microwave. Japanese Patent Application Laid-open No. 6169576 and U.S. Patent No. 4,210.67 address this problem.
Publication No. 4 is known. This device attaches a conductive member to a resin lid, converts the energy absorbed by the conductive member into heat, and automatically makes a hole in the lid to release the pressure inside.

すかしなければならなかった。(Problems to be solved by the invention) On the other hand, food products tend to deteriorate when exposed to oxygen or light, and resin sheet materials alone are not strong enough, so a thin aluminum film is laminated on lids, etc. This is how aluminum is laminated onto the lid.
The above purpose is distantly related, as it prevents the transmission of oxygen and light and also increases the intensity.
A method such as the Makki opening means in which an absorbing material that absorbs microwaves is provided on the surface of only a resin sheet material such as plastic cannot be used because aluminum adds conductivity. was there. This is the same when metal is vapor-deposited on a resin sheet, and containers made of laminated metal members must be made by drilling holes in the container or removing the lid before heating in a microwave oven. I had to.

That is, slits were provided in a metallic member such as aluminum foil used for the exterior material, and the thermoplastic resin coated in the slits was melted by microwaves from a microwave oven.

われている。1 and 2 show a first embodiment of a container according to the present invention. This container 1 consists of a cup-shaped plastic storage container 2 and a lid 4 attached to this storage container 2, and food is stored inside the storage container 2. The lid 4 is made of a laminated material in which a thermoplastic plastic sheet 6 and a thin aluminum film 8 are laminated, and is removably fixed tightly to the flange portion 9 of the container 2 by heat sealing. The thermoplastic sheet 6 is a film made of polyethylene terephthalate, generates heat by microwaves from a microwave oven, and melts itself due to the heat. 11118 is integrally adhered to this thermoplastic sheet 6, and a slit 10 is formed in the inside thereof. The slit 10 is a notch with a width of about 1 mm and a length of about 50 mm,
This part is covered only with the thermoplastic sheet 6.

品質を低下させることなく食品を加熱できる。Therefore, when the container 1 is heated in a microwave oven, the food inside is heated, and the microwaves absorbed by the thin film 8 are concentrated in the slit 10, causing the thermoplastic sheet 6 to generate heat. Then, when the temperature of the thermoplastic sheet 6 reaches the melting temperature, the container 1 is opened. Therefore, if the thickness of the thermoplastic sheet 6 and the shape of the slit 10 are appropriately selected so that the thermoplastic sheet 6 melts faster than the boiling of water in the food, the internal pressure of the container 1 can be adjusted appropriately. This allows the steam to escape and prevents damage to the container 1, and also prevents the release of a large amount of steam, unlike when heating with the lid removed.
Food can be heated without reducing quality.

When the slit 10 is provided in this manner, the slit 10 portion is melted by heating in a microwave oven, allowing the internal pressure inside the container 1 to escape, and a cut is formed along the slit 10. Therefore, the container 1 is heated so that the contents can be removed as soon as the food is heated.

ト１０により離れ容器１を開口できる。FIG. 4 shows a third embodiment of the container 1. In this example, the thin film 8 is provided on the body 3 of the container 2, and the slit 10 is provided along the body 3. This slit 10 is
It is formed around almost the entire circumference of the storage container 2, and is located at a higher position than the liquid level of the contents in the storage container 2, that is, the food. According to this example, when heated in a microwave oven, the slit 10 portion melts, allowing internal pressure to escape, and the upper part of the storage container 2 is separated from the lid 4 by the slit 10, allowing the container 1 to be opened.

溶融開口させることができる。Further, the lid 4 may be formed from a metal plate instead of a resin laminated on a metal foil such as aluminum. An example of this is shown in FIG. This is a lid 4 that has been previously formed from a metal plate using a press or the like, and is attached to the mouth of a plastic storage container 2 by caulking or the like.
This lid 4 is usually a lid that can be opened by using a can opener or by pulling it open along a cut groove formed around the can opener. The container 1 shown in the figure has such a lid 4 provided with a slit 10, and this slit 1o covered with a thermoplastic plastic sheet 6. In this case as well, the microwave energy can be concentrated in the slit 10 portion, and the thermoplastic sheet 6 can be melted and opened during food heating in the microwave oven.

are provided, and the protrusions 20 are butted against each other. In this way, the degree of concentration of microwaves is increased in areas where the interval is narrow, and the melting rate can be partially increased even when the microwave energy is weak or when a member that does not easily generate heat is attached. Therefore, if the protrusion 20 is provided in the slit 10 along the joint 12 between the container 2 and the lid 4 as shown in FIGS. The container 1 generates heat and opens, and the pressure inside the container 1 is released through this opening, and the entire slit 1o melts after a predetermined period of time has elapsed, that is, when the heating of the food product is finished. Then, the container 1 can be prevented from bursting with minimal release of steam, and the lid 4 can be opened automatically. Also, the protrusion 2
The number 0 is not limited to -, but may be provided in a large number.

In this case, the resin selected for the thermoplastic sheet does not generate heat in the microwave.
Alternatively, even if the amount of heat generated is very small and is not sufficient to melt, a material that easily generates heat by microwaves may be provided close to or connected to the slit 10.

Therefore, even if a container uses a metallic member as its exterior material, when it is heated in a microwave oven, the microwave energy will be concentrated in the slit, and the thermal energy will melt the thermoplastic resin and cause the container to explode before it ruptures. The pressure inside the container can be released. Therefore, food can be heated in the microwave in the container without removing the lid or making holes before heating. Furthermore, if a slit is provided along the joint between the lid and the container body, the container can be opened by creating a cut along the slit. Furthermore, when the width of the slit is changed, melting of the thermoplastic resin can be partially accelerated.
