Description

[Detailed description of the invention] This invention has an outlet for the liquid inside the pot on the peripheral wall of a tabletop thermos pot, and is designed to reliably prevent water leakage and to provide a simple and inexpensive overall structure. An embodiment of the present invention will be described below with reference to the drawings.A wide-mouthed cap 2 is removably attached to the top of a container 1 surrounded by a heat insulating material, and a cylinder is attached near the bottom of the peripheral wall of the container 1. A circular valve seat 6 is provided between the injection passage 4 in the passageway 3 leading into the container 1 and the discharge port 5 leading to the outside, and a circular valve seat 6 is provided between the injection passage 4 of the valve seat 6 and the A partition wall 7 is provided in the opposite extension direction, a cylindrical space 8 is formed outside the partition wall 7 of the water passage 3, and a disc-shaped push button 9 is movable in the space 8. The above push button 9 can be accommodated freely.
A shaft rod 10 protruding in the direction of the container 1 is provided through a hole bored in the partition wall 7 into a space communicating with the injection path 4 surrounded by the valve seat 6 and the outlet 5. A small diameter portion 11 is formed near the tip of the valve 13, and a valve 13 is fitted into the small diameter portion 11, and the valve 13 and the shaft rod 10 are fixed by a mounting portion 12 in which the tip of the small diameter portion 11 is melted and deformed by heat. The outer diameter of the valve 13 is made somewhat larger than the inner diameter of the valve seat 6, and
In the direction of the push button 9, the minimum diameter is smaller than the inner diameter of the valve seat 6, and the taper part 15 has a root diameter that almost matches the inner diameter of the valve seat 6. From this taper part 15 to the outer circumference of the valve 13, A close contact portion 14 is formed in close contact with the valve seat 6, and an outer circumferential wall 17 is inclined or curved in cross section so that the outer diameter in the push button 9 direction becomes gradually smaller in the space 8 in the push button 9 direction from the partition wall 7. The backing 16 has a pot in which the hole 19 of the backing 16 is brought into close contact with the outer periphery of the shaft rod 10, and a coil spring 20 is interposed between the inclined or curved outer peripheral wall 17 of the backing 16 and the push button 9. and implement the present invention.

18 in the figure is a wall surface that comes into close contact with the partition wall of the backing 16. Since this wall surface 18 is pressed against the partition wall 7 by the coil spring 20 and comes into close contact, there is a gap between the partition wall 7 and the backing 16. This reduces the chance of water leaking.

21 is a collar provided on the outer periphery of the water passage 3, which connects the water passage 3 to the container 1.
This is designed to stabilize the mounting position and mounting condition when mounted on the machine.

In addition, when implementing the present invention, the mounting portion 12 is the small diameter portion 1.
The tip of the valve 1 is not limited to one that can be deformed by heat, but a screw or the like having a seat larger than the diameter of the small diameter part 11 can be used to
3 may be fixed to the small diameter portion.

In the above embodiment, the outer circumferential wall of the backing 16 is inclined or curved so that the diameter becomes smaller in the direction of the push button 9, and the coil spring 20 is interposed between the outer circumferential wall 17 and the push button 9. 20 is backing 1
6 in the direction of the partition wall 7, the partition wall 7 and the wall surface 18 of the backing 16 are kept in close contact with each other at all times to prevent water leakage therebetween. Since the ends of the coil springs 20 are in contact with each other, the ends of the coil springs 20 and the outer peripheral wall 1 are in contact with each other.
7 and narrows the backing 16, the degree of close contact between the hole in the backing 16 and the outer periphery of the shaft rod 10 is improved, and water leakage therebetween can be prevented.

The present invention is as described above. Hot or cold liquid is stored in the container from the direction of the cap, and the liquid in the container is poured from the outlet by simply pressing the push button of the water passage and releasing the valve from the valve seat. The water passage portion has an extremely simple structure and can be provided at low cost since it can be formed of four members: the water passage, the push button, the shaft rod, the backing, and the coil spring.

In addition, the outer diameter of the valve is made somewhat larger than the valve seat, and the valve is provided with a part of the taper in the direction of the push button, and the root of the taper part has a diameter that almost matches the inner diameter of the valve seat. Therefore, when the valve seat is sealed with a valve, the outer periphery of the valve and the valve seat form a concentric circle, and the distance from the valve seat to the outer periphery of the valve is uniform, ensuring that water leaks are prevented with less force. This has the advantage that the fitting position of the valve does not easily change.
