Japanese Unexamined Patent Publication No. 2011-56142

However, it may be difficult to attach the lid to the container in the correct positional relationship, such as when the lid is heavy.

Therefore, an object of the present invention is to provide a pot or the like in which a lid can be easily attached to a container in a correct positional relationship.

The pot according to the present invention includes a container having a container body and a lid having a lid body and attached to the upper part of the container. On the upper part of the container body, a lid receiving surface having an annular planar shape, an upper peripheral wall having a cylindrical shape extending upward from the inner peripheral portion of the upper surface of the lid receiving surface, and a plurality of protruding outwards in the radial direction from the outer wall of the upper peripheral wall. A first protruding piece of the above and a guide ring extending upward from the upper peripheral wall are provided. A plurality of second projecting pieces projecting inward in the radial direction are provided on the inner peripheral wall of the outer peripheral ring forming the outer periphery of the lower end of the lid body. The guide ring is used to keep the opening surface of the lid parallel to the opening surface of the container when attaching the lid to the container.

When the opening surface of the lid is inclined with respect to the opening surface of the container and the lid receiving surface, the inner wall of the lid comes into contact with the outer wall of the guide ring. Therefore, when the lid is attached to the container, the guide ring keeps the opening surface of the lid substantially parallel to the opening surface of the container.
That is, the guide ring maintains the lid directly above the container.
Therefore, even if it is hidden behind the lid and the positional relationship between the first protruding piece of the container and the second protruding piece of the lid is difficult to see, the lid is placed on the container in a state of being located directly above the container. It can be done easily.
That is, it is possible to make it difficult for the lid to be placed on the container in a state where the lid is displaced from directly above the container.
Even when the lid is heavy, the lid can be easily attached to the container in the correct positional relationship.

Preferably, the outer peripheral wall of the guide ring has a tapered shape such that the outer diameter of the lower part is large and the outer diameter of the upper part is small.

It can be easily aligned with the lid and the container through the tapered portion of the outer peripheral wall of the guide ring.

More preferably, the vertical length of the guide ring is longer than the vertical length of the upper end of the first protruding piece and the lid receiving surface.

While the lid passes through the long guide ring, the opening surface of the lid can be made parallel to the opening surface of the container as compared with the form in which the lid passes through the short guide ring.

More preferably, the inner peripheral wall of the guide ring has a tapered shape such that the inner diameter of the lower portion is small and the inner diameter of the upper portion is large. When the pot is heated, a part of the packing attached to the lid comes into contact with the inner peripheral wall.

Since the packing is brought into contact with the tapered portion of the inner peripheral wall of the guide ring, the packing can be reliably contacted at the time of heating as compared with the form in which the tapered portion is not provided, and the sealing can be ensured.

The pot container according to the present invention includes a container body. On the upper part of the container body, a lid receiving surface having an annular planar shape, an upper peripheral wall having a cylindrical shape extending upward from the inner peripheral portion of the upper surface of the lid receiving surface, and a plurality of protruding outwards in the radial direction from the outer wall of the upper peripheral wall. A first protruding piece of the above and a guide ring extending upward from the upper peripheral wall are provided. A second projecting piece projecting inward in the radial direction is provided on the inner peripheral wall of the outer peripheral ring forming the outer periphery of the lower end of the lid main body of the lid attached to the upper part of the container. The guide ring is used to keep the opening surface of the lid parallel to the opening surface of the container when attaching the lid to the container.

As described above, according to the present invention, it is possible to provide a pot or the like in which the lid can be easily attached to the container in the correct positional relationship.

(effect)
When the opening surface PL2 of the lid 30 is inclined with respect to the opening surface PL1 and the lid receiving surface 12 of the container 10, the inner wall of the lid 30 comes into contact with the outer wall of the guide ring 17. Therefore, when the lid 30 is attached to the container 10, the guide ring 17 maintains a state in which the opening surface PL2 of the lid 30 is substantially parallel to the opening surface PL1 (cover receiving surface 12) of the container 10.
That is, the guide ring 17 maintains a state in which the lid 30 is located directly above the container 10.
Therefore, the lid 30 is located directly above the container 10 even if it is hidden behind the lid 30 and the positional relationship between the first protruding piece 15 of the container 10 and the second protruding piece 33 of the lid 30 is difficult to see. In the state, it can be easily placed on the container 10.
That is, it is possible to make it difficult for the lid 30 to be placed on the container 10 in a state where the lid 30 is displaced from directly above the container 10.
Even when the lid is heavy, the lid 30 can be easily attached to the container 10 in the correct positional relationship.

If the lid 30 is placed on the container 10 in a state of being displaced from directly above the container 10, the lid 30 may be placed on the container 10 in a state of being tilted with respect to the container 10 (Fig.). 9).
In this case, some of the second protruding pieces 33 are located below the first protruding piece 15, and the second protruding piece 33 located below the first protruding piece 15 becomes the first protruding piece 15. It gets caught and the lid 30 is hard to come off from the container 10.
In the present embodiment, as shown in FIG. 9, the guide ring 17 makes it difficult for the lid 30 to be placed on the container 10 in a state of being tilted with respect to the container 10.

In the present embodiment, the pressure cooker 1 has been used to describe a pot in which the lid 30 can be easily attached to the container 10 in the correct positional relationship, but the pot is not limited to the pressure cooker in which cooking is performed in a high pressure state. It may be an ordinary pot.
