Description

[Detailed description of the invention] The present invention is an air pot configured to have an air pump installed inside the top lid, pressurize the air pump with a pressurizing body, and pour out the liquid inside the heat-insulating container to the outside through the pouring pipe. , relates to an air pot that can prevent liquid from pouring out when not in use, and aims to provide an air pot that not only allows reliable pouring and pouring prevention operations but also is easy to handle and convenient. It is.

An embodiment of the present invention will be described below in detail with reference to the drawings.

In the old drawing, 1 is an air pot, and a mechanical air pump 3 is installed inside the upper lid 2, and a pressurizing body 5 for operating the air pump 3 is slidably provided in a through hole 4 formed in the upper lid 2. By pressurizing the air pump 3 with the pressurizing body 5 and blowing air into the heat insulating container 6, the liquid in the heat insulating container 16 is forced to be sent to the outside through the pouring pipe 7.

A flange 8 is provided protruding from the lower outer periphery of the pressurizing body 5.

On the other hand, on the inner periphery 9 of the upper lid 2, a plurality of restraining pieces 11, 11, .

This restraining piece 11. It is formed to have vertical dimensions corresponding to the moving distance of the pressurizing body 5.

A stopper piece 11 is provided on the outer peripheral edge of the flange 8 only at a certain rotational position.
Notches 12, 12 that allow downward movement of the flange 8 in accordance with
...... is established.

A rotating ring 14 is provided on the upper surface side of the flange 8 and can be rotated by being supported by the tongue pieces 13, 13, .

The rotating ring 14 has an operating piece 15 protruding from the upper surface of one side of the upper lid 2.
It is made to protrude outside through the long hole 16.

Further, on the lower surface of the rotating ring 14, a short locking piece 17.17 is provided.
A long locking piece 18.18 is provided protrudingly, and both locking pieces 1
7 and 18 are inserted into engagement holes 19 and 20 formed in the flange 8.

Furthermore, a pair of recesses 21.2 are provided on the inner circumferential surface 28 of the rotating ring 14.
2 are provided at appropriate intervals in the circumferential direction.

A recess 22 is formed on the outer peripheral surface 24 of the cylindrical portion 23 on the outer periphery of the through hole 4 of the upper lid 2.
A protrusion 25 is provided which engages with one of the four parts 22.
When the notch 12 and the stopper piece 11 are engaged with each other, the notch 12 and the stopper piece 11 correspond to each other, and when the protrusion 25 is engaged with the other recess 21, the notch 12 is located at a position moved laterally from the upper part of the stopper piece 11. ing.

An exit mark 26 and a stop mark 27 are written on the top surface of the rotating ring 14, and when the rotating ring 14 is in the position where pouring is possible, the exit mark 26 appears in the elongated hole 16, and vice versa. The stop mark 27 is configured to appear in the elongated hole 16 in a position where dispensing is not possible.

The operation of the air pot configured as above will be explained.

First, when pouring out the liquid in the heat-insulating container 6, press the operation piece 15.
If the rotating ring 14 is slid in the direction of the arrow When the ring 22 engages with the protrusion 25, there is no resistance, and it can be felt by hand that the rotating ring 14 is located at the desired position.

At the same time, a mark 26 appears in the elongated hole 16 and can be visually confirmed.

The rotating ring 14 is held at that position and does not move unless an external force is applied to the operating piece 15.

In this state, the notch 12 of the flange 8 is connected to the stopper piece 11.
Since it corresponds to the upper surface, the pressurizing body 5 can be moved downward. Therefore, when the pressurizing body 5 is pressed and moved downward, the air pump 3 is activated and the liquid in the heat insulating container 6 is poured out. It can be pumped to the outside through pipe 7.

And if you do not use air pot 1, operate the operation piece 15.
When the rotating ring 14 is slid in the direction of the arrow Y, the inner circumferential surface 28 of the rotating ring 14 comes into contact with the protrusion 25 of the upper cover 2, giving an appropriate resistance and rotating while preventing rattling. When 21 and the protrusion engage, there is no resistance,
It can be seen that the rotation ring 14 is located at the desired position.

At the same time, a stop mark 27 is formed in the elongated hole 16 and can be visually confirmed.

The rotating ring 14 is held at that position and does not move unless an external force is applied to the operating piece 15.

In this state, the notch 12 of the flange 8 is connected to the stopper piece 11.
Since the pressurizing body 5 is located laterally away from the upper surface, the pressurizing body 5 is caught in the stopper piece 11 and is prevented from moving downward, so that the pressurizing body 5
Even if you press , the liquid in the heat-insulating container 6 cannot be poured out.

As shown in the embodiments above, according to the air pot of the present invention, since the protrusion and the retaining part are provided on the circumferential surfaces of the pressurizing body and the upper lid, it is possible to not only prevent the rotating ring from rattling, but also prevent the rotating ring from shaking. The moving ring can be held in a predetermined position, allowing reliable pouring and pouring prevention operations.

Moreover, the stop position of the rotary ring for preventing or allowing the downward movement of the pressurizing body can be clearly grasped just by the touch of the hand, and there is no twisting and turning at the stop position, and furthermore, it is easy and convenient to handle.
