Description

[Detailed Description of the Invention] The present invention relates to an air pot of a type in which an air pump is disposed inside an upper lid that opens and closes in a chime pattern, and the pump discharges liquid to the outside.

Conventionally, as shown in Fig. 1, in this type of air pot, a medium bottle 1 for storing liquid such as hot water is housed in a main unit 2, and upper lids 3 connected in a numbered manner to the main unit 2 are opened and closed. An air pump 4 is mounted inside the upper lid 3 to form a lid unit 5.

When the lid unit 5 is closed, the ventilation tube 7 of the air pump 4 comes into close contact with the air blowing hole 6a of the inner stopper 6, so that the air pump 4 is brought into communication with the inner bottle 1. When the air pump 4 is pressed, the air inside the medium bottle 1 is compressed and the liquid 1a is poured out through the liquid pumping pipe 8 and the liquid pouring pipe 9.

However, when pouring liquid into the inner bottle 1, the inner stopper 6
The liquid pumping tube 8 and the liquid pouring tube 9, which are integrally arranged with the inner stopper, must be taken out from the inner bottle 1, which is inconvenient for use. Since it is wet, the location is a problem in terms of cleanliness or dirt. Further, there is a drawback that the liquid pumping tube 8 of the inner stopper 6 may be damaged by falling from a high place.

In view of the above-mentioned drawbacks, the present invention provides an air pot that allows liquid to be injected into a medium bottle by simply opening the lid unit without taking out the inner stopper or liquid spouting tube from the medium bottle.

An embodiment of the present invention will be described below with reference to FIG. In FIG. 2, the same parts as in FIG. 1 are denoted by the same reference numerals, and the explanation thereof will be omitted.

The air pump 4 installed inside the lid unit 5 is integrally provided with an inner plug portion 10, and an air blowing hole 10a of the inner plug portion 10 is communicated with a ventilation cylinder (not shown) of the air pump 4. ing.

An inner cavity 10b is formed in the inner plug part 10 and is continuous with the air blowing hole 10a, and an inlet part 9a of the liquid spouting tube 9 is inserted therethrough.

Further, a sealing plug 11 made of a heat-resistant elastic material such as silicone rubber is fitted into the inner plug portion 10 located on the opening side of the inlet portion 9a and the inner cavity 10b. This sealing stopper 11 fits into the bottle mouth 1b of the medium bottle 1.

The inlet portion 9a of the liquid pouring pipe 9 and the liquid pumping pipe 8
A bellows-shaped bent portion 12 made of a heat-resistant soft material is provided between the upper end of the holder and the upper end of the holder.

This bent portion 12 may be a simple tube.

In the above configuration, when the lid unit 5 is opened by rotating the lid unit 5 by a predetermined angle using the numbered part 13 as a fulcrum, the sealing plug 11 fitted into the inner plug part 10 provided inside the lid unit 5 simultaneously opens the inner bottle. 1, and the liquid pumping tube 8 along with the liquid spouting tube 9 is removed from the bent portion 1.
2. At this time, the lower end of the liquid pumping tube 8 is inside the medium bottle 1, but the outer diameter of this tube is sufficiently smaller than the inner diameter of the bottle mouth 1b, so when pouring the liquid into the medium bottle 1 from the bottle mouth 1b, It does not interfere in any way.

Next, when the lid unit 5 is closed, the liquid pumping tube 8 and the liquid pouring tube 9 gradually become straight, and the sealing stopper 1
1 is fitted into the bottle mouth 1b and sealed.

Thereafter, by pressing down the lid 13, the air pump is contracted and the pressurized air is passed from the cylinder through the air blowing hole 10a and the inner cavity 10b of the inner stopper 10 to the inner bottle 1.
The liquid 1a in the bottle is forced out of the bottle through a liquid pumping pipe 8 and a liquid pouring pipe 9.

The length of the liquid pumping tube 8 is such that when the lid unit is closed, the distance to its lower end is slightly longer than the distance to the bottom surface 1c of the medium bottle 1, and this longer length is absorbed by the elasticity of the bent portion 12. By doing so, there is no danger of the pumping pipe 8 pendulum-like swinging within the medium bottle 1 and destroying the medium bottle 1. In addition, a recess may be provided in the bottom surface 1c, or a permanent magnet may be placed in the medium bottle to connect the liquid pumping tube 8.
Shaking may be prevented by attaching a magnetic material to the lower end of the member.

As is clear from the above-mentioned embodiments, this device allows liquid to be injected simply by opening the lid unit, and furthermore, the liquid pumping pipe acts as a surcharge when liquid is injected, and the liquid flows through the pumping pipe. In addition to being easy and convenient to pour into the bottle, there is no need to take out the inner stopper, liquid pumping tube, or liquid dispensing tube, so there is no need to worry about where to place it, it is clean, and there is no risk of damage from falling. Nor.

Claims (1)

[Scope of utility model registration request] A top cover with a built-in air pump is attached to the main unit housing the medium bottle so as to be openable and closable, and a liquid pumping pipe and liquid pumping pipe are inserted into the medium bottle by the pump operation of the air pump. In an air pot configured to discharge liquid to the outside through a liquid spouting pipe communicating with the pipe, an inner plug part that holds the liquid spouting pipe and has a sealing plug is integrally attached to the upper lid. An air pot characterized in that the liquid pumping tube is connected to the liquid pouring tube via a bendable bending part.
