Description

[Detailed explanation of the idea] The present invention relates to a pot with heat retention properties.

Generally, in conventional pots of this kind, the main body is integrally formed by arranging a bottomed inner cylinder and an outer cylinder coaxially, and filling a heat insulating material such as foamed polyurethane resin between these cylinders. The structure was such that hot water, cold water, etc. could be kept warm and sealed inside the inner cylinder. By the way, there is a limit to the heat retaining ability of the above-mentioned heat retaining structure, and the liquid in the pot usually reaches a temperature outside the usable range after about 5 to 10 hours. Therefore, in order to always store hot or cold water at a usable temperature in the pot, the liquid must be reheated (cooled) or discarded each time the pot's heat retention capacity lasts. It was necessary to add new hot or cold water.

However, as mentioned above, with conventional pots, it is necessary to transfer the liquid from the pot to another container in order to reheat (cool) it, which is complicated, and it is uneconomical to discard the liquid. There was a drawback.

The present invention was developed based on the above-mentioned circumstances, and its purpose is to provide a pot that allows the sealed liquid to be easily reheated or recooled without the need to transfer it to a separate container, and that also allows for smooth opening and closing operations. The goal is to provide a pot that can be used.

In order to achieve the above object, the present invention is characterized by the following structure. That is, it has a cylindrical heat-retaining container with a bottom and a spout on the top wall that can be opened and closed by a predetermined rotation operation, and is inserted into and removed from the hollow part of the heat-retaining container with the top wall exposed. The spout includes a hermetic container that can be inserted freely, and a rotation prevention means that prevents the hermetic container from rotating relative to the heat-insulating container, and the spout has a spout body and a spout body. A screw body is screwed into a screw hole drilled in the central axis of the screw body, a knob provided at one end of the screw body, and a small diameter portion formed at the other end of the screw body are engaged with each other while forming a gap. and a sealing member attached together.

Hereinafter, the present invention will be explained in detail based on an embodiment shown in the drawings.

FIG. 1 is a perspective view showing the overall structure of the pot of this embodiment. In the figure, 1 is a cylindrical heat-retaining container with a bottom, and 2 in the figure has a spout 3 on the upper wall that can be opened and closed by a predetermined rotational operation, and the upper wall is exposed. The airtight container is removably inserted into the hollow part of the heat insulation container. 4 in the figure is a lid that is removably attached to the opening of the heat insulation container 1 and covers the upper wall of the airtight container inserted into the heat insulation container 1. .

The detailed structure of the heat insulating container 1 is as shown in FIG. That is, the heat insulating container 1 is constructed by coaxially joining an outer body 5 having a cylindrical shape with a bottom and an inner body 6 having a cylindrical shape with a bottom, and filling the space between these bodies 5 and 6 with a heat insulating material 7. Forms a heat-insulating structure. Further, a stepped portion 8 is formed near the opening of the internal body 6 to increase the opening diameter. Projections 9 that protrude toward the center and extend in the axial direction are formed at several locations on the peripheral wall on the opening side of the stepped portion 8. In the figure, 10 is a shoulder strap, and 11 is a lid attachment part.

The detailed structure of the airtight container 2 is as shown in FIG. That is, the airtight container 2 has a removable top wall 13 attached to the opening of a container body 12 having a bottomed cylindrical shape to form a hermetic structure. Container body 12
is formed to have an outer diameter that allows it to be inserted into the hollow portion of the heat-insulating container 1. The upper wall 13 is the step part 8 of the heat-insulating container 1
It is formed with an outer diameter that allows it to be inserted into the opening side.
The upper wall 13 has a spout 3 having a configuration as shown in FIG.
is installed.

This spout 3 includes a spout body 15, a screw body 16,
A knob 1 provided at one end of this screw body 16
7, and a sealing member 18 attached to the other end of the screw body 16. The sealing member 18 and the threaded body 16 are attached to the small diameter portion 19 of the threaded body 16.
and the engagement hole 20 of the sealing member 18 are engaged with each other. In this attachment part, a predetermined gap is formed between the outer periphery of the small diameter part 19 and the inner periphery of the engagement hole 20, and the engagement between the stepped part 21 formed at the base end of the small diameter part 19 and the sealing member 18 is The opening peripheral portion 22 of the mating hole 20 comes into contact with and separates from the opening peripheral portion 22 of the matching hole 20. Therefore, this spout 3
When the sealing member 18 is moved up and down by rotating the knob 17 to open and close it, the opening and closing operations can be performed smoothly since a ventilation hole is formed by the gap.

A large number of protrusions 23 are continuously formed on the circumferential surface of the upper wall 13 at predetermined intervals. These protrusions 23 each protrude radially and extend in the axial direction, and the intervals between the protrusions are set to a size that allows the protrusions 9 formed on the inner periphery of the opening of the heat insulating container 1 to fit therein. There is.

Due to the projections 23 continuously formed on the circumferential surface of the upper wall 13 and the projections 9 formed on the inner periphery of the opening of the heat-insulating container 1, the airtight container 2 rotates relative to the heat-insulating container 1. A rotation prevention means is configured to prevent this from happening. That is, when the airtight container 2 is inserted into the hollow part of the heat-insulating container 1, the upper wall 1
The protrusions 23 of No. 3 and the protrusions 9 of the heat-insulating container 1 engage with each other to prevent the rotation. Since the pot of this embodiment is provided with such a rotation prevention means, the rotation operation for opening and closing the spout 14 can be performed accurately.

The pot configured as described above has the following effects.

Hot water, cold water, etc. sealed in the airtight container 2 are kept warm by the heat insulating container 1. After the duration of the heat retention performance of the heat insulation container 1 has elapsed, the hot or cold water, etc. in the airtight container 2 can be reheated (cold heating) easily by removing the airtight container 2 from the heat insulation container 1 and leaving the airtight container 2 as it is. .

Note that the present invention is not limited to the above-mentioned embodiment. Further, although the pot in the above embodiment is a portable pot with a shoulder strap 10 attached to the heat insulating container 1, the present invention can also be applied to a large pot used at home. Furthermore, the rotation prevention means for preventing the closed container from rotating relative to the heat-insulating container may be, for example, a structure in which the internal body of the heat-insulating container and the closed container are formed into corresponding square shapes. It goes without saying that various other modifications can be made without departing from the gist of the present invention.

As is clear from the above description, the present invention has the effect that the liquid sealed in the container can be easily reheated or recooled by removing the airtight container from the heat-insulating container and leaving the airtight container intact. play. In addition, when opening and closing the sealing member by moving the knob up and down by rotating the knob, a ventilation hole is formed by the gap between the small diameter part formed at the other end of the screw body and the sealing member. This has the effect that operations can be performed smoothly.
