[Structure] A branch pipe 13 is provided above the water level pipe 11, the branch pipe 13 is communicated with the inside of a container such as a bottle 1, and the upper end of the water level pipe 11 is exposed to a container outer body such as a shoulder body 3, The cap 19 was fitted on the exposed end.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid container having a water level tube such as an air pot or an electric pot.

[0002]

[Prior Art]

 In a liquid container such as an air pot or an electric pot, a water level pipe communicating with the bottom of the container is generally provided in order to display the amount of liquid inside. The upper end of this water level pipe is bent to communicate with the container.

[0003]

[Problems to be solved by the device]

 Since the liquid contained in the container passes through the inside of the water level pipe, if the liquid is barley tea, coffee, etc., the stains from those liquids will adhere, and the transparency of the water level pipe will gradually decrease, and the position of the liquid Is often difficult to see from the outside.

However, in the conventional air pot and the like, there is a problem that the inside of the water level tube cannot be easily cleaned because the upper end of the water level tube is bent and communicates with the upper end of the container.

Therefore, an object of this invention is to provide a liquid container in which the water level pipe can be easily cleaned.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a liquid container having a water level pipe communicating with the bottom of the container, in which a branch pipe communicating with the inside of the container is provided above the water level pipe, and the upper end of the above water level pipe is provided. Alternatively, the cylindrical portion of the container exterior body connected to the water level pipe is exposed to the outside of the container exterior body, and the exposed end is capped.

[0007]

[Action]

 In the above liquid container, the air and liquid inside the water level pipe escape to the inside of the container through the branch pipe, so that the same water level display as in the conventional case can be displayed. When cleaning the inside of the water level tube, remove the top of the water level tube that is exposed to the outside of the exterior body or the cap of the tubular part of the exterior body, and insert a brush from the top end to perform cleaning.

【Example】

 The embodiment shown in FIG. 1 is for an air pot. A pumping pipe 2 is inserted into the upper end opening of the inner bottle 1 of the air pot, and the pumping pipe 2 is provided in a shoulder body 3 which constitutes a part of an external body of the air pot, and a communication passage 4 and a discharge pipe 4 '. Through the discharge port 5. Further, an air hole 9 is provided in the lower plate 8 of the bellows pump 7 housed inside the lid 6, and communicates with the inside of the inside bottle 1.

A lower end of a water level pipe 11 is connected to the bottom of the middle bottle 1 via a joint tube 10. The water level pipe 11 is composed of a main body 12, a branch pipe 13 and an auxiliary pipe 14.

The main body 12 of the water level pipe 11 is a straight transparent pipe, which is vertically attached along the inner surface of a transparent panel 16 (see FIG. 5) provided on the body 15 of the air pot, and is branched at the upper end thereof. The pipe 13 is connected. The upper end of the branch pipe 13 communicates with a part of the communication passage 4 described above. The auxiliary pipe 14 is connected on the same axis as the main body 12 at the connecting portion of the branch pipe 13.

The main body 12 of the water level pipe 11 and the auxiliary pipe 14 may be integrally formed.

As shown in FIG. 2, a receiving collar 17 is integrally provided on the outer peripheral surface of the upper end portion of the auxiliary pipe 14, and the receiving collar 17 is fitted to the lower end of the peripheral wall of the hole 18 formed in the shoulder body 3. The upper end of the auxiliary tube 14 is opened into the hole 18, and the rubber cap 19 (in the case of FIG. 2) or the screw cap 20 (in the case of FIG. 3) is fitted into the open end.

The auxiliary tube 14 may be installed inside the shoulder body 3 as shown in FIG. 4, and may be connected to the tubular portion 21 provided on the shoulder body 3 via a packing 22. In this case, the cap 19 or 20 is fitted to the open end of the tubular portion 21.

The water level tube 11 and the panel 16 covering the water level tube 11 are usually provided in the center of the front of the air pot, but since the discharge port 5 is provided in the upper part of the center of the front of the air pot, The water level tube 11 and the panel 16 are provided at positions displaced from the center to one side as shown in FIG.

When the water level pipe 11 and the panel 16 are provided in the center of the front, the position of the discharge pipe 4 ′ is shifted as shown in FIG. So that it is connected to the discharge port 5 in the section.

Since the air pot of the embodiment is as described above, when the bellows pump 7 is operated, the internal pressure of the middle bottle 1 rises and the air is discharged through the pumping pipe 2, the communication passage 4 and the discharge pipe 4 ′. The liquid is discharged from the outlet 5. At this time, the liquid flows through the main body 12 of the water level pipe 11 and the branch pipe 13, but does not flow because the upper end of the auxiliary pipe 14 is closed by the cap 19 or 20. When the operation of the bellows pump 7 is stopped, the pressure in the middle bottle 1 is lowered, so that the flow in the water level pipe 11 is also stopped, and the water level at the same height as the water level in the middle bottle 1 appears in the main body 12.

When cleaning the water level tube 11, the cap 19 or 20 is removed, and a brush is inserted from the upper end of the auxiliary tube 14 to clean the inside of the main body 12.

[0018]

[Effect of the device]

 As described above, according to the present invention, the branch pipe is provided above the water level pipe, and the branch pipe communicates with the inside of the container to allow the flow of air and liquid. It is possible. Also, since the upper end of the water level pipe or the cylindrical part of the container outer body connected to the water level pipe is exposed on the container outer body, and the exposed end is capped, remove the cap and brush the water level pipe from outside the outer body. By inserting, the water level pipe can be easily cleaned.
