Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a liquid container in which the amount of liquid in the inner container is visually checked from the front of the outer case.

[Conventional technology]

Conventionally, liquid containers in which the liquid level inside the inner container is visually checked from the front of the outer case are equipped with an inner container made of aluminum material and formed into a cylindrical shape with a bottom, and through holes are bored at the top and bottom of the front of the inner container. At the same time, an elongated transparent hollow glass tube is provided, and the upper and lower ends of this glass tube are communicated with the through holes at the front upper and lower ends of the inner container via rubber seals, and the glass tube of the outer case surrounding the inner container is connected to the inner container. In this type of liquid container, the front surface corresponding to the position was cut and a transparent plate was placed over the cut part (for example, as shown in Japanese Utility Model Application Publication No. 57-99537).
The inner container, the glass tube that displays the liquid level in the inner container, and the rubber seal that connects the through hole of the inner container and the top and bottom ends of the glass tube are made of different materials and are separate parts, making it a complex and complex structure with many parts. The structure is complicated to install, and if the inner container is molded from synthetic resin material, it is difficult to seal it with the glass tube that displays the liquid volume, so the product cost is low because it is molded from expensive aluminum material. I was unable to measure it.

[Purpose of invention]

The present invention was developed in view of the above points, and it has an extremely simple structure, is easy to assemble, and can be manufactured at low cost.The present invention also has a highly durable liquid level display section, is safe, and can be used for many years. Therefore, it is an object of the present invention to provide a liquid container for keeping heat and cold that is easy to see.

[Structure of the idea]

In order to achieve the above-mentioned purpose, in the liquid container for heat/cold storage of the present invention, a heat insulating material is provided between the side periphery and the bottom of the outer case and the inner container, respectively, and the inner container is made of a transparent material. It is made of synthetic resin, and a part of the circumference of the inner container is recessed inward to form a recessed space, with the upper end attached to the upper front end of the inner container and the lower end attached to the lower front end of the inner container. An internal hollow branch pipe is provided integrally with the inner container, communicating with the inner space of the inner container, and positioning the front wall at a position substantially equivalent to the original side circumferential surface of the inner container. 〓 formed between the back wall of the branch canal and the front wall of the inner vessel.
A clear plate is provided in between, and the front surface of the outer case is cut vertically along the branch pipe, so that the liquid level in the inner container can be visually checked from the front surface of the outer case through the branch pipe.

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings.

The liquid container 1 includes an inner container 2 having a cylindrical shape with a bottom, an outer case 3 surrounding the inner container, a shoulder member 4 coupled to the upper end of the outer case, a bottom member 5 coupled to the lower end of the outer case, and an upper end of the shoulder member. It is composed of a middle sleeve 6 that is detachably attached toward the mouth of the inner container.

The inner container 2 is formed into a bottomed cylindrical shape from a synthetic resin material such as transparent plastic, and has a hollow branch pipe 7 integrally molded in the front part. That is, Fig. 2,
As shown in FIG. 3, the inner container 2 has a flat front wall 2b connected in a straight line between both end points 2a, 2a having a circumference shorter than half the circumference of the inner container 2. A recessed space 2A is formed by forming all the parts except for. Therefore, the cross-sectional shape of the inner container at this portion is tunnel-like. Then, between the upper and lower ends, an internally hollow branch pipe 7 is integrally blow-molded with the inner container 2 with its upper and lower ends communicating with the internal space of the inner container 2, and The front wall 7a of the tube 7 is located on the original circumferential surface of the inner container 2, and a gap 8 with both left and right ends open is formed between the back wall 7b and the front wall 2b of the inner container 2. ing.

9 is a clear plate that connects the flat front wall 2b of the inner container 2 and the branch pipe 7.
In the space 8 formed between the back wall 7b of the
It is stretched over the back wall 7b of the branch pipe 7 and functions to clearly display the liquid level inside the branch pipe.

Further, on the front side of the upper end of the inner container 2, a mouth 2C having a screw 2B provided on the outer periphery is provided.

The exterior case 3 is formed by bending a thin iron plate into a cylindrical shape, and the upper and lower ends of this cylindrical shape are bent inward. The outer case 3 surrounding the inner container 2 is cut at the front surface corresponding to the branch pipe position of the inner container so that the branch pipe 7 can be seen through from the front surface of the outer case, and a transparent plate is provided with a window frame 10 at this cut portion. 11 is installed.

The shoulder member 4 covers the upper end of the inner container, has an opening communicating with the mouth of the inner container, has an annular fitting groove at the lower end of the outer peripheral wall, and has a bent portion of the upper end of the outer case inserted into the annular fitting groove. are force-fitted and connected.
Reference numeral 12 denotes a ring body that connects the mouth of the inner container and the opening of the shoulder member. Reference numeral 13 denotes a handle integrally molded on the rear part of the shoulder member, and the lower end of the handle is screwed to the lower end of the rear surface of the outer case. Reference numeral 14 designates a handle pivotally supported on the left and right side walls of the shoulder member. be. The bottom member 5 covers the bottom of the inner container, and has a fitting groove provided at the upper end of the outer circumferential wall, into which the bent portion of the lower end of the outer case is forcibly fitted and connected. As shown in FIG. 2, the inner pin 6 is removably screwed into the mouth of the inner container 2 from the upper end of the ring body 12.
Reference numeral 15 is a tip, and reference numeral 16 is a heat insulating material such as polystyrene foam, which is interposed between the side periphery and the bottom of the outer case 3 and the inner container 2, respectively, as shown in FIG.

[Effect of idea]

According to the present invention, a vertically long branch pipe is provided in front of the inner container, and this branch pipe is integrally molded with the inner container from a transparent synthetic resin material, so the structure is simple and the number of assembly parts is extremely small. Furthermore, there is no need to assemble a mechanism for displaying the amount of liquid, making it possible to significantly reduce product costs. Moreover, the present invention is particularly advantageous in that the inner container and the branch pipe are integrally formed, and the branch pipe is positioned at approximately the same position as the side circumferential surface of the inner container and is integrally formed with the inner container. By the way, it keeps you warm.
By effectively utilizing the gap between the inner container and the outer case for loading insulation material for cold storage, the branch pipes are completely inside the outer case and do not protrude outward. Because of this structure, there is no chance of the branch pipe colliding with other objects and being damaged, dramatically increasing durability and safety. This effectively prevents the risk of the liquid level being stuck and making it impossible to clearly see the liquid level, allowing the clear plate to function effectively, and making it possible to clearly see the liquid level for many years. Moreover, we have now been able to provide a liquid container with high practical value that has heat and cold insulation effects.
