Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a liquid container such as a thermos flask that has an inner container housed inside an exterior body.

(Prior Art) FIG. 5 shows a general bottom structure of a conventional liquid container such as a thermos flask. In this conventional liquid container, the outer case 54 of the exterior body 52 is formed of an opaque material such as a sheet metal. In addition, the inner container 53 has a bottom member 5.
By screwing the internally threaded member 57 into the case 5, the internally threaded member 57 is tightened and attached to the lower surface (not shown) of the upper part of the exterior body.

However, in this conventional liquid container, the exterior body 5
Since the inner container 53 housed in the inner container 53 cannot be seen from the outside, it is difficult to confirm whether the inner container 53 is held in a normal posture when assembling the inner container 53 (pushing it up with the internal screw member 57). Therefore, there was a possibility that the inner container 53 would be fixed while being shifted in the horizontal direction as shown by the chain line 53'. or,
In this conventional liquid container, the inner container 53 is attached to the outer case 52 by screwing the internal thread member 57, so special work ( (Insertion work for internally threaded parts) is required. Furthermore, during assembly, the inner container 53 is inserted into the outer case 52 from the bottom side, but at this time, the outer case 52 is usually placed on a workbench in an inverted position. If the assembly work is performed with the exterior body 52 placed on the workbench in an inverted position, the top surface of the exterior body 52 (the top surface in the upright position) will rub against the top surface of the workbench, which will be easily visible from the outside. There was a problem that the top surface of the exterior body was easily scratched.

(Purpose of the invention) In view of the above-mentioned problems of conventional liquid containers, the present invention is designed to make it possible to see through the inner container housed inside the outer case from the outside, and to simplify the installation work of the inner container. The object of the present invention is to provide a liquid container with a high temperature.

(Means for Achieving the Object) The present invention provides a liquid container in which an inner container is housed inside an outer case, in which the outer case is formed into a cylindrical body having a bottom and an upper opening larger than the body diameter of the inner container.

It is characterized in that the annular member is pressed against the lower surface of the inner container by the coil spring via the inner peripheral edge on the upper end side of the annular member.

(Function) According to the liquid container of the present invention, during assembly,
The inner container can be housed inside the bottomed cylinder while it is placed in an upright position on the workbench. or,
Since the inner container is supported in an upwardly biased state by a coil spring, the inner container can be held by simply assembling the shoulder member to the bottomed cylinder. In addition, even if there is a slight dimensional error in the vertical direction of the inner container or the outer case, the dimensional error can be absorbed by the coil spring. Furthermore, by forming the bottomed cylindrical body of the exterior body from a transparent material, the state (posture) of the inner container can be seen through from the outside; Even if the coil spring is used as a coil spring, the coil spring cannot be seen from the outside due to the annular member for concealment. Furthermore, since the annular member for blindfolding is provided with its upper inner peripheral edge pressed against the bottom surface of the inner container by a coil spring, the annular member is prevented from shifting within the bottomed cylinder, and the annular member is There will be no gap between the upper end of the member and the bottom of the inner container.

By pressing the inner circumferential edge 22a on the upper end side of the annular member 22 against the bottom surface of the inner container with the coil spring 10 in this way, it is possible to prevent the annular member 22 from being misaligned, and the upper end of the annular member 22 and the bottom surface of the inner container can be prevented from shifting. There will be no gap between the two.

Further, in the liquid container of the first embodiment, the shoulder member 6 is attached to the upper part of the body 4 of the bottomed cylinder 2A by screw connection. That is, by forming a male thread 24 on the outer surface of the upper part of the body part 4 and forming a female thread 25 on the inner surface of the lower part of the outer circumferential wall 16 of the shoulder member 6, both screws 24 and 25 are screwed together and tightened. Both members (body part 4 and shoulder member 6) are fixed to each other. Incidentally, when the shoulder member 6 is screwed onto the body section 4, the coil spring 10 is in an appropriately compressed state. Note that the reference numeral 26 indicates the outer peripheral wall 16 of the shoulder member 6.
This is a ring made of a band-shaped metal plate wrapped around the outer surface, and the handle 12 is fixed to the ring 26. It should be noted that the handle 12 of this first embodiment is in the form of a vertically elongated bar whose upper end is bent into an inverted U shape.

To explain how to assemble the liquid container of the first embodiment, first place the bottomed cylinder 2A on a workbench in an upright position, and then
The bottom plate 21, the coil spring 10, and the annular member 22 are sequentially installed on the bottom 5 of the body 4 through the upper opening 4a of the body 4, and then the inner container 3 is placed through the upper opening 4a of the body 4.

Therefore, the number of steps for assembling the liquid container main body 1 can be reduced, and the liquid container When assembling the main body 1, the state (posture) of the inner container 3 can be seen from the outside, and when the liquid container is used, the state (for example, damage) of the inner container 3 can be checked from the outside of the body 4. Further, even if the inside of the exterior body 2 is made to be visible through the body 4, the coil spring 10, cap 13, etc. are covered by the annular member 22 for concealment, so that they cannot be seen from the outside. The effect of disappearing is obtained.

(Effect of idea) The liquid container of the present invention has the following effects.

(1) Since the body 4 of the exterior body 2 is made of a transparent material, the condition of the inner container 3 can be seen directly from the outside of the body 4, and therefore the contents can be checked when the inner container 3 is assembled. Since the posture (inclination) of the container 3 can be adjusted while viewing from the outside of the body 4, the assembly work can be easily performed. Furthermore, even if, for example, the support member supporting the inner container 3 loosens and the inner container 3 is tilted during use, or if the inner container 3 is damaged, this can be easily detected from the outside of the body 4. can do.

(2) Since the inner container 3 is supported in an upwardly biased state by the coil spring 10, special work is required to support the inner container 3 within the exterior body 2 (conventionally, the inner container 3 is This eliminates the need for tightening with other members, and reduces assembly man-hours.

(3) Since the inner container 3 is supported by biasing with the coil spring 10, the outer body 2 or the inner container 3
Furthermore, even if there is a slight manufacturing dimensional error in the vertical direction, the dimensional error can be absorbed by the coil spring 10.

(4) The exterior body 2 is constructed by attaching a shoulder member 6 to the top of the bottomed cylinder 2A, and when assembling the inner container 3, the bottomed cylinder 2A is placed in an upright position on a workbench. Since it can be carried out by placing it on the body, the top surface of the exterior body, which is easily visible from the outside during assembly, will not rub against the workbench, and the top surface of the exterior body will not be scratched by sliding contact with the workbench (the bottom surface of the exterior body will not be scratched). There is a risk of contact with the workbench, but the bottom surface of the exterior body is difficult to see from the outside).

(5) Since the cover member 22 is provided at the bottom of the bottomed cylindrical body 2A, even if the interior of the exterior body can be seen through the body 4,
The coil spring 10 will not become invisible from the outside and will not look bad.
