Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cooking container. In particular, the present invention relates to a cooking container equipped with a lid having a vacuum pressure valve for making the interior airtight and suitable for cooking cooked rice.

[0002]

[Prior art]

 Conventionally, utility model registration No. 1638461 (name of device: rice cooker with floating lid) and No. 1760479 (stopper of rice cooker) have been disclosed as cooking containers and lids for kettle rice cookers and the like. .

The sealing of these rice cooking containers and the lid is performed by forming the opening edge of the container relatively wide, forming a recess, and loading an annular packing at the bottom thereof, and then loading the packing from the top with the edge of the lid. It was pressed down and closed, and four removable metal fittings were used to snap and close at four points.

The conventional sealing of the container and the lid is configured to be guaranteed and maintained by the packing and the stopper, but it is possible to cook twelve or twenty cooking containers at the same time as in the case of commercial kettle cooking. However, when cooking a large number of foods at the same time, the packing comes off when attaching or cleaning the lid, and it takes time to re-attach it.

Further, since the conventional cooking container is mainly intended for cooking rice, the shape of the lid does not anticipate a cooking form in which a large amount of water is ejected, and it is premised on Japanese rice. It was a dedicated structure for cooking rice. However, due to the distribution of foreign rice and the diversification of food types, the usage patterns of cooking containers for this type of business have diversified, and the development of cooking containers that meet such demands has been awaited.

[0006]

[Problems to be solved by the device]

 The first problem to be solved by the present invention is to provide a cooking container that can cook delicious rice or the like in a short cooking time. The second is to provide a cooking container that can handle many types of cooking by having a structure in which the boiling liquid due to boiling can be slightly out of the container. Third, make sure that the packing does not come off easily when the lid is attached to the container, when the lid is opened, or during routine cleaning. Fourth, the problem is that the packing can be removed for cleaning. Fifthly, the packing is provided on the lid side instead of the container as in the conventional case. If this is on the lid side, it is not necessary to remove the packing from the kettle for fast food such as cooking rice in a container and setting the container as it is on the kettle base (makeup base) and then serving it on the table. As a result, it is possible to save a lot of labor and keep the provided container clean. Sixth, the problem is to maintain the airtightness even if packing is provided on the lid side. Seventhly, the subject is to attach a stopper to the lid to prevent the stopper from being lost and to facilitate the attachment and detachment.

[0007]

[Means for Solving the Problems]

 The present invention addresses the above-described problems, and provides a cooking container that includes a lid having a packing and a container, and that can shorten cooking time such as cooking rice and perform delicious cooking. This cooking requires pressure on the food and sufficient steam space. Here, the present invention forms a raised portion in the center of the top plate, equips a pressure valve having a vacuum maintaining mechanism with a recessed part in the center, and an annular convex part on the outer peripheral edge of the top plate. A concave part that serves as a tray for boiling water is formed on the outside of the annular convex part, and a hanging edge is connected to the outside of the annular convex part.An annular packing is attached to the top surface of the inside of the annular convex part. A cooking container characterized in that it comprises a lid provided with a retaining member on which a ring is suspended, and a container having an outer peripheral surface provided with a brim for hanging the ring of the retaining member.

With this configuration, for example, when cooking cooked rice in this cooking container, pressure is applied in a sufficient steam space to cook rice for a short time, and after completion of cooking, the container becomes a vacuum container like canned food, By releasing the vacuum state, the stopper can be removed and the lid side can be opened until the packing is provided, so that the cooked rice can be provided without impairing the flavor. Further, for example, in the case of rapid boiling of oden or the like, steam or boiling water by boiling is collected in an annular recess on the upper surface of the lid. Since it is a cooking container that can be applied to the evaporation of water and cooking that causes spillage, there is a possibility that spillage may occur frequently.For example, boil and cook each container as in a small pot of oden, and then provide it to the table It can also be used for mass cooking of fast food.

Since the packing that seals the lid and the container is attached to the back of the lid so that it cannot be easily removed, there is no risk of loss and the packing is not on the container side, so There is no need to remove the packing when taking it out, and by wiping the opening quickly, it can be provided as a clean, clean container. That is, the container itself provided to the customer is easily maintained clean. Also, since the lid has four stoppers attached to it, the stopper can be attached and detached without loss as compared with the conventional configuration in which the stoppers are separated and independent. Becomes extremely easy.
