The contact members 17 and 17' on the drive circuit 14B side are connected to the main body I of the exterior case 1.
Both ICs are provided across the upper rim of the bottle C and the rim of the medium bottle 2.

The insert is held in a gasket 2a sandwiched between the lower opening 1' that connects the outer case 1 and the mouth edge of the medium bottle 2 in a state facing the opening 2A, and the outer case 1 and the medium bottle 2 are The space between them is used as a facility space, and the electric wires 16, 16' led out from the drive circuit 14B are crimped and connected.

The contact members 18, 18' on the electrodes 14A, 14A' side are attached to the plug 3 in such a manner that they come into contact with and separate from the contact members 17, 17' on the drive circuit 14B side when the plug 3 is opened or opened.

19 in the figure is a power supply battery.

4 to 6 show different embodiments, and the other embodiment shown in FIG. 4 is one in which the other electrode 14A' is attached to the outer periphery of the medium bottle 2. In the other embodiment shown, the other electrode 14A' is provided inside the liquid pumping pipe 5, and the sixth electrode 14A' is
In another embodiment shown in the figure, the liquid lift pipe 5 is constructed by connecting two stainless steel semi-cylindrical bodies 5A, 5A' in a cylindrical shape with insulating synthetic resins 5B, 5B, and one semi-cylindrical body One electrode 14A is also used in the body 5A, and the other semi-cylindrical body 5A'
The other electrode 14A' is also used.

Reference numeral 20 in FIG. 5 is an insulating spacer that maintains the distance between the electrodes 14A, 14A'.

Furthermore, in the above embodiment, the capacitance type detection device 14 was explained, but the detection device 14 to which the present invention is applied detects the liquid level step by step using a plurality of electrodes 14A of different lengths. It may be a so-called conductivity type detection device,
In addition, it may be provided in a portion of the exterior case 1 or the top cover 4 other than the locations shown in the embodiment.

Further, the display device 15 may be one that displays information step by step as in the embodiment, or one that displays analog or digital information.

Examples of the power source battery 19 include primary batteries, secondary batteries, and solar cells such as dry batteries, mercury batteries, silver batteries, lithium batteries, alkaline batteries, etc., and examples of the power source include external power sources such as general household power sources. It may be.

The liquid lift pipe 5 may be made of stainless steel, iron, aluminum, or synthetic resin.

In addition to the thermos shown in the examples, the present invention also applies to liquid containers configured to take out the liquid in the container by pumping air with an electric pump, and liquid containers configured to take out the liquid in the container by using an electric screw. It can be applied to containers, etc.

In summary, in the liquid container with a liquid level detection and display device according to the present invention, the contact member 17 on the drive unit 14B side is provided across the mouth edge of the container 2 and the upper mouth edge of the outer case main body IC. It is characterized in that it is interposed between the lower opening 1' which connects both 2.1C and the mouth edge of the container 2.

Therefore, according to the present invention, the lower mouth 1' and the container 2 are connected.
Since the contact member 17 is mounted by effectively utilizing the connecting means between the lower mouth 1' and the edge of the container 20, such as by fixing and holding the contact member 17 by the 0 edge, the contact member 17 can be mounted without any structure. The contact member 17 can be mounted reliably and strongly.

Moreover, since the contact member 17 can face the space between the container 2 and the outer case 1, the contact member 17
The electric wire 16 that connects the drive unit 14B to the drive unit 14B can be disposed in the space between the container 2 and the outer case 1, thereby making it possible to perform wiring processing advantageously.
