Description

[Detailed explanation of the invention] This invention is a heat-retaining pot, more specifically, it has a removable cap with a double structure inside and outside, and by pushing down the outer cap, a water inlet appears and the water inlet is opened, allowing hot water to flow inside the medium bottle. This relates to a heat-retaining pot that can be filled with water.

There are various types of heat-retaining pots available on the market, such as a bushing type that uses the air force of a pump, or a sealed type that allows water to be poured in by loosening the stopper. Not only is it unsightly because the tip protrudes outward from the main body, but also, with screw-type closures, it is difficult to distinguish between the sealed state when the cap is tightened and the state where water can be poured when the screw is loosened. This has the disadvantage of handling, as it is often left unattended with the stopper loosened.

When not in use, the water inlet is covered by the outer cap and the water inlet passage is kept closed. When the outer cap is pushed down and set, the water inlet is opened and the water inlet appears, allowing hot water to be poured immediately. The present invention provides a heat-retaining pot with a unique structure in which, when the outer cap that has been pushed down further is restored upward, the water inlet passage is closed and at the same time the water inlet is hidden by the outer cap.

The drawings showing the embodiments of the present invention will be explained below.
As shown in FIG. 1, the heat-retaining pot of the present invention consists of a main body 1, a detachable cap main body 2, and a handle 3, and its appearance resembles that of a portable water bottle.

However, as shown in FIGS. 2 and 3, the cap main body 2 includes an inner cap 4 that is removably fitted to the upper part of the pot main body 1, and an outer cap that is attached to the inner cap 4 so as to be movable up and down. 5 and a valve body 6 for opening and closing the injection channel of the inner cap 4, which will be described later.

The inner cap 4 includes an annular fitting peripheral wall part 9 that is screwed into a screw part 8 provided on the upper side surface of the outer case 7 of the pot body 1, and an outer case 7 that presses and seals the mouth edge of the medium bottle 10. a close contact portion 13 that presses against the opening edge 11 of the container via a sealing material 12, a cylindrical portion 14 directed toward the inside of the medium bottle 10, and a water inlet opened at a position substantially flush with the outer peripheral surface of the peripheral wall portion 9. 15, and a tunnel-shaped water injection channel 16 formed between the cylindrical portion 14 and the water injection port 15.
The upper peripheral wall 17 of No. 6 has a structure that projects upward.

On the other hand, the outer cap 5 includes a cylindrical portion 18 and an upper surface portion 19 that substantially cover the outer circumference and upper surface portion of the inner cap 4, and the upper surface portion 19 is provided with the injection channel 16. It has an opening 20 through which the upper peripheral wall 17 can pass.

Further, the above-described valve body 6 passes through a valve seat portion 21 having a size that can close the lower end opening of the cylindrical portion 14 of the above-described inner cap 4 and a through hole 22 provided in the upper portion of the cylindrical portion 14. The attachment that reaches the back surface of the outer cap 5 consists of a shaft portion 23, and in this embodiment, the shaft portion 23 has a cylindrical shape and is attached to a cylindrical portion 24 hanging down at the center position of the back surface of the outer cap 5. As shown in FIG. 3, it is integrally fixed to the inner center of the outer cap 5 by a threaded rod 25, and by attaching the valve body 6 to the outer cap 5, the inner cap 4 and the outer cap 5 are inseparable from each other, and the outer cap 5 is set so as to be able to be pushed down with respect to the inner cap 4, and the upper peripheral wall 17 of the injection channel 16 of the inner cap 4 fits into the opening 20 of the outer cap 5. Outer cap 5 and inner cap 4 depending on the
and can be rotated as one unit.

The through hole 2 of the cylindrical portion 14 of the inner cap 4 described above
2 is present on the upper surface and the cylindrical portion 24 of the outer cap 5.
A compression spring 26 is interposed between the inner surface where the outer cap 5 and the valve body 6 are present, and the outer cap 5 and the valve body 6 are always urged upward with respect to the inner cap 4. The portion 21 is the cylindrical portion 14 of the inner cap 4
The opening 27 is closed.

Furthermore, above the base of the handle 3 of the pot body 1, there is an outer cap 5 pushed down against the elasticity of the spring 26.
A locking member 28 is provided for holding the push-down position.

As shown in FIG. 3, the locking member 28 includes a hook body 31 whose base portion 29 is pivotally attached to the pot body 1 side and whose tip claw portion 30 is directed toward the cylindrical portion 18 of the outer cap 5;
It consists of a plate spring 32 for elastically urging the hook body 31 toward the cylindrical portion 18 side of the outer cap 5, and the outer cap 5 is changed from the unused state shown in FIG. 3 to the state shown in FIG. 4. When pressed down, the protrusion 33 provided on the cylindrical portion 18 of the outer cap 5 comes into contact with the tip claw portion 30 of the hook body 31, pushes the hook body 31 slightly outward, and passes through. After that, the hook body 31 is restored and its tip claw portion 30 is located above the protrusion 33, and the protrusion 3
The tip claw portion 30 of the hook body 31 engages with the top surface of the hook body 31 to maintain the pressed down position of the outer cap 5, and the engagement is released by rotating the hook body 31 outward with a fingertip. However, the structure is such that the outer cap 5 can be restored upward by the elasticity of the plate spring 32 described above.

However, the structure of the locking member 28 that performs the above-mentioned function is not particularly limited. For example, as shown in FIG. An upper slide piece 36 and a lower slide piece 37 each having a claw portion 35 at the tip are attached so as to be movable back and forth,
The sliding piece 36.3 is moved by the internal spring 38.
7 toward the cylindrical portion 18 of the outer cap 5,
The outer cap 5 may be engaged with the hole 39 when the outer cap 5 is pressed down.

As detailed above, in the heat retention pot of the present invention, the inner cap 4 having the water injection channel 16 communicating with the interior 910 inside the pot body 1 and the water injection port 15 facing the side is attached to and detachable from the top of the pot body 1. The inner cap 4 is provided with an opening/closing valve body 6 for the injection channel 16 of the inner cap 4 on the back surface, and the above-mentioned injection valve is provided on the upper surface portion 19. An outer cap 5 is provided with an opening 20 through which an upper circumferential wall portion 17 forming a water channel 16 can pass, and is elastically attached to the pot body 1 so as to be able to be pushed down. Since the locking member 28 is provided, when the outer cap 5 is pushed down during use, the outer cap 5 is held in the depressed position by the locking member 28, as shown in FIG. At the same time, the water inlet 15 appears and the water inlet 16 is opened.

Therefore, in this state, when the pot body 1 is tilted by the handle 3, the hot water in the medium bottle 10 can flow out through the water injection port 15 through the injection channel 16.

After pouring water, if the pot body 1 is placed and the locking member 28 is operated outward, the outer cap 5 returns to its upward movement, and the cylindrical portion 18 hides the water inlet 15, and the valve body 6 closes the inlet channel 16. The container is closed, and the flow between the medium bottle 10 and the outside air is cut off, thereby preventing a change in the temperature of the hot water inside the medium bottle 10 and preventing hot water from flowing out when the pot body is tipped over.

When the outer cap 5 is further pushed down for use, the upper circumferential wall portion 17 forming the water injection channel 16 protrudes from the upper surface of the outer cap 5 through the opening 20 on its surface, and water injection can be performed. It is extremely convenient to use because you can see at a glance if something is there or if you have forgotten to close it.

Moreover, since the water inlet 15 is completely closed by the outer cap 5 when not in use, there is no intrusion of insects, lumps, etc., and furthermore, when the outer cap 5 is in its original state,
As shown in Fig. 1, the outer cap 5 has a simple and unique appearance, as if fitted with a cap having approximately the same outer diameter as the pot body 1, and has an excellent aesthetic effect as a furniture item. It is suitable not only for keeping hot water warm in general households, but also as a pot for mixing Western liquor with water and hot water.
