Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a pump-filled liquid container with a liquid volume display tube for externally displaying the liquid inside the inner container.

(Prior art) In a conventional pump filling type liquid container with a liquid volume display tube, the liquid injection pipe for guiding the liquid to be dispensed and the liquid volume display tube for displaying the liquid volume in the inner container are separate. As a result, the number of parts increases and the structure becomes complicated.

In addition, in conventional pump-type liquid containers with a liquid volume display tube, the liquid volume display tube was interposed between the container case and the inner container, so the area where the liquid volume display tube was installed was relatively dark. It becomes difficult to see the height of the liquid level in the liquid level display tube, and the angle range in which the liquid level display tube can be seen from outside the container case becomes narrow, and the liquid level display tube is located between the container case and the inner container. When the liquid container is interposed, it is necessary to increase the outer diameter of the container case relative to the outer diameter of the inner container, resulting in a problem that the entire liquid container becomes larger.

Furthermore, a pump-filling type liquid container in which a liquid volume display tube also serves as a liquid filling pipe has been known. However, since the liquid volume display tube is located outside the inner container, its heat retention ability is low, and the temperature of the liquid inside the liquid volume display tube (liquid injection pipe) drops in a short period of time. There was a problem in that the temperature of the liquid inside the injection pipe was poured out, and the temperature of the entire liquid poured out became low.

(Purpose of the invention) In view of the above-mentioned problems of the conventional pump injection type liquid container with a liquid volume display tube, the present invention has been developed to simplify the configuration, make the liquid volume display part easy to see, and to An object of the present invention is to provide a pump-filling type liquid container that can be made compact and further prevent the temperature of the liquid in a liquid volume display tube (liquid filling tube) located outside the inner container from decreasing. It is.

(Means for Achieving the Object) The pump injection type liquid container of the present invention houses an inner container having a lower opening in a container case, and further has a pump device for blowing pressurized air into the inner container. A liquid filling tube having a transparent tube portion serving as a liquid level display portion in the inner container is communicated with the lower opening, and when liquid is poured out, the liquid in the inner container is directed upward from the lower opening side through the transparent tube portion. The transparent tube part of the liquid injection tube is installed in a state facing the outside of the container case, and the outer side of the transparent tube part is covered with a cover member, and the liquid injection tube is The device is characterized in that a heater for heating the liquid in the liquid injection pipe is provided at the lower end position and outside the portion located inside the container case.

(Function) The present invention provides the following effects. That is, (1) the liquid injection tube has a transparent tube section that serves as a liquid level display section in the inner container, so the liquid injection tube can also be used as a liquid level display tube; (2) the transparent tube section can be used as a liquid level display section; Since it faces the outside of the body case, light from the outside can easily illuminate the part where the transparent tube part is installed, making the part where the transparent tube part is installed brighter, and the range of angles in which the transparent tube part can be seen from outside the body case. (3) Since the transparent tube part faces the outside of the container case, the gap between the outer surface of the inner container and the inner surface of the container case can be reduced, making it possible to make the entire liquid container more compact. (4) If the transparent tube part faces the outside of the container case, the liquid flowing into the transparent tube part will be easily cooled down in a relatively short time. Since the heater is provided outside the part located inside the outer case, the liquid inside the liquid injection tube can be heated, and even if the liquid injection tube is outside the inner container, the temperature of the liquid inside the liquid does not drop. The following effects can be obtained.

(Embodiment) Hereinafter, the pump injection type liquid container of the present invention will be explained based on the illustrated embodiment. The pump injection type liquid container of the embodiment shown in FIG. a liquid container main body 1 which houses a liquid container 5 and further has a dish-shaped shoulder member 6 placed on the upper part of the container case 4;
It has a lid body 2 that houses a bellows-type pump device 9 therein.

The lid body 2 is pivotally attached to the upper part of the liquid container body 1 by a hinge.

The inner container 5 has a vacuum double wall with relatively large-diameter openings 18 and 19 formed in its upper and lower parts, respectively, and the lower opening 19 is hermetically sealed with a bottom plug member 20.

A liquid supply port 7 communicating with the upper opening 18 of the inner container 5 is formed approximately in the center of the shoulder member 6 .

A plug 8 is integrally formed at the bottom of the pump device 9 housed in the lid 2, and the plug 8 closes the liquid supply port 7 when the lid 2 is closed. Note that when the container is closed, the pump device 9 and the inside of the inner container 5 are communicated with each other.

A liquid injection pipe 10 for guiding the liquid W in the inner container 5 to the outside has a spout pipe 13 at the upper and lower ends of a vertically long transparent tube section 12 with joint pipes 14 and 15, respectively.
and the proximal side tube 11 are connected laterally. The liquid injection tube 10 is inserted into the inner container by passing the proximal end 11a of the proximal side tube 11 into the bottom plug member 20 provided in the lower opening 19 of the inner container with the transparent tube portion 12 oriented vertically on the outer side of the inner container 5. It is installed in such a way that it opens at the bottom of the inside. The transparent tube portion 12 and spout tube 13 of the liquid injection tube 10 are installed so as to project outward from a vertically long window hole 24 formed in the front surface of the container case 4. In this way, by installing the vertically elongated transparent tube portion 12 so as to face the outside of the container case 4, the gap between the outer surface of the inner container 5 and the inner surface of the container case 4 can be reduced. , the outer diameter of the container case 4 can be made smaller than the outer diameter of the inner container 5. In addition, when the transparent tube section 12 is installed outside the container case 4 in this way, a large amount of light from the outside irradiates the transparent tube section 12 installation part, making the transparent tube section 12 bright, and the liquid inside it becomes bright. The height of the transparent tube part 12 can be easily seen from a wide angle range outside the container case 4.
become visible. Further, a cover member 25 with a viewing window 26 is provided on the front surface of the container case 4 so as to cover the transparent tube part 12, and the height of the liquid inside the transparent tube part 12 can be visually observed through the viewing window 26. We are making it possible to do so.

Further, in this liquid container, a heater 23 for heating the liquid flowing into the liquid injection pipe 10 is provided at the lower end of the liquid injection pipe 10 and outside the portion located inside the container case 4. . In addition, like this liquid container, the transparent tube part 12 of the spouting tube 10 is attached to the container case 4.
If the transparent tube section 12 is installed so as to face the outside, the liquid inside the transparent tube section 12 will cool down more easily than when the transparent tube section 12 is installed with the heater 23 housed inside the container case 4. By providing this, the liquid in the transparent tube section 12 can be heated, and the problem that the liquid whose temperature has dropped at the beginning when pouring out the liquid is poured out can be solved.

Further, in the liquid container of this embodiment, an electric heater 21 is provided at the bottom of the inner container 5 (on the top surface of the bottom plug member 20), so that the liquid W in the inner container 5 can be boiled or kept warm. . Note that the lead wire 22 of the electric heater 21 passes through the bottom plug member 20 and is guided below the inner container 5.

In FIG. 1, reference numeral 27 denotes a pipe back plate provided on the back side of the transparent tube section 12.
is for making it easier to see the liquid level inside the transparent tube section 12. Reference numeral 28 denotes a bottom member of the liquid container main body 1, and 29 denotes an internally threaded member. By tightening the internally threaded member 29, the inner container 5 is inserted through the intermediate member 30.
is tightened between the internal threaded member 29 and the lower opening member 6.

In the pump injection type liquid container shown in FIG. 1, when liquid is not being poured, the amount of liquid in the inner container 5 can be detected by visually observing the liquid level in the transparent tube section 12 through the viewing window 26. When injecting liquid, when the pump device 9 is contracted, the pump device 9
Pressurized air from the inner container 5 causes the liquid W in the inner container 5 to be poured out from the lower opening 19 side, through a series of liquid injection pipes 10, and from the spout of the spout pipe 13 to the outside.

FIG. 2 shows a pump-filling type liquid container according to another embodiment of the present invention.
3 and a sideways liquid spouting pipe 34 are attached in a mutually communicating state. The cylindrical hole 35 and the upper end of the transparent tube part 12 are configured to communicate with each other via a communication hole 36 formed in the lower mouth member 6, and when pouring out liquid, the liquid pumping tube 33 side and the transparent tube The liquid W that has been pumped up separately on the side of the portion 12 joins together inside the liquid spouting pipe 34, and the merged liquid W is poured out from the spout 34a.

(Effects of the invention) Next, the effects of the invention will be explained. The pump injection type liquid container of the invention has the following effects.

(1) The liquid injection pipe 10 for guiding the liquid in the inner container 5 to the outside has a transparent tube part 12 that serves as a liquid level display part in the inner container 5. It can also be used as a display tube section, thereby reducing the number of parts and simplifying the configuration.

(2) Since the transparent tube part 12 faces the outside of the container case 4, the transparent tube part 12 can be installed more easily than in the conventional case where the transparent tube part is interposed between the container case and the inner container. A large amount of light from the outside is irradiated onto the part, and the part where the transparent tube part 12 is installed becomes brighter, and the angle range in which the transparent tube part 12 can be seen from the outside of the container case 4 becomes larger, so that the transparent tube part 12 It becomes easier to see the height of the liquid level inside.

(3) Since the transparent tube part 12 is installed so as to face the outside of the container case 4, the gap between the outer surface of the inner container 5 and the inner surface of the container case 4 can be reduced. Therefore, the entire liquid container can be made compact.

(4) Since the outside of the transparent tube section 12 is covered with the cover member 25, the transparent tube section 12 can be protected.

(5) Since the heater 23 is provided at the lower end of the liquid injection tube 10 and outside the portion located inside the outer case 4, the liquid in the liquid injection tube 10 is heated by the heater 23 and is always kept at a high temperature. Even if the transparent tube section 12 of the liquid injection tube 10 is located outside the container case 4 and the liquid inside the transparent tube section 12 is structured to cool easily, high-temperature liquid is always poured out. can do.
