Description

[Detailed Description of the Invention] The present invention relates to the structure of the bottom body of a portable thermos bottle, particularly a metal thermos bottle.

Portable thermos bottles are made of metal, generally made of stainless steel, with the outer body of the vacuum double bottle exposed and omitted, and the shoulder body A and the top B attached to the top, as shown in Figure 5, and the lower end. The bottom body C is attached to the shoulder body A, and the supporting rod D ₁ for the strap is attached to the opposite position of the shoulder body A.
There is one _in which a support rod D ₂ is provided protrudingly, and a support rod D ₃ is made to project from the bottom body C directly below one support rod D 2 so that it can be hung both vertically and horizontally.

This type of thermos bottle has a support rod for the hanging string that protrudes from the bottom, so it has the disadvantage that it can easily get damaged by hitting other objects or catch on clothes when dropped or hung vertically. It was hot. In addition, since the support rods protrude from three sides, the design does not necessarily have a smooth design.

In view of these points, the present invention is to form a recess by recessing a part of the bottom body attached to the lower end of a metal vacuum double bottle, and to drill a through hole in the top wall of the recess. In addition, the above-mentioned drawbacks are solved by storing and fixing an auxiliary tool having a support rod for a lanyard protruding inside the bottom body, and having the support rod protrude into the recess from the through hole.

Hereinafter, the portable thermos bottle of the present invention will be described based on the attached drawings, which are examples.

The portable thermos bottle shown in FIG. 1 has a shoulder body 3 having a protruding support rod 2 for a carrying string with a roll pin attached to the top of a metal vacuum double bottle 1. 4 is screwed on, and a bottom body 5 is fixed to the lower end of the double vacuum bottle 1.

In order to fix the bottom body 5, the outer wall of a metal vacuum double bottle is fitted into a short cylindrical part 6 formed by projecting downward, and is fixed with screws 7.

For example, a saucer-shaped bottom body 5 integrally molded from a synthetic resin material is partially recessed from the lower end to form a recess 8, and a through hole 9 is bored in the top wall 8a of the recess 8. Furthermore, a groove 12 is cut into the side wall 8b.

An auxiliary tool 10 is stored and fixed in the bottom body 5 to form a support rod for the strap.

That is, the support rod 11 is vertically provided from the substrate 10a, which is shaped to fit closely along the inner wall surface of the recess 8, and the support rod 11 is fixed by protruding into the recess 8 of the bottom body 5 from the through hole 9. . The support rod 11 for the lanyard is formed into a substantially U-shape by installing a pin 11b on a pair of left and right leg pieces 11a, 11a, but it is also possible to bend a single metal wire into a U-shape. The auxiliary tool 10 can be fixed to the bottom body 5 by screwing or gluing, but the upper end 10b of the auxiliary tool 10 should be brought into contact with the bottom wall of the double vacuum bottle 1, and the lower end should be fixed to the bottom of the vacuum bottle 1. By engaging with a part of the body 5, it is possible to eliminate the possibility of accidental movement simply by assembling.

Furthermore, if the leg piece 11a of the support rod 11 is fitted into the groove 12 carved in the side wall 8b of the recess 8, the fixation of the auxiliary tool 10 can be further strengthened, and the support rod Even if an impact force is applied, there is no possibility that the leg pieces will wobble or break, making it stronger.

In other drawings, 13 is a chip for exhausting the vacuum double bottle, 14 is a protrusion formed on the short cylindrical portion 6 of the vacuum double bottle to strengthen the fitting of the bottom body 5, and 15 is a screw 7. The head of the screw 7, which is a base for screwing the screw 7 and is exposed on the bottom body, is covered with a fitting member 16.

In metal double vacuum bottles, the tip 13 for evacuation is located in the center of the bottom as shown in Figures 2 and 3, and in the periphery as shown in Figure 4. However, as can be seen from FIGS. 3 and 4, it goes without saying that the present invention can be applied to both types.

According to the portable thermos bottle of the present invention, since it can be carried in a horizontal position, the support rod for the carrying string formed on one of the lower ends does not protrude outside the bottle, and is located within the recess in the bottom body, so when carrying it, Alternatively, the possibility that the support rod will be damaged by hitting a rock or the like when dropped can be reduced as much as possible, and it will not get caught on clothes when carried.

Moreover, it can be designed to have a clean appearance.

Furthermore, in manufacturing the portable thermos bottle of the present invention, there is no need to incorporate support rods into the large bottom body, and it is efficient to simply assemble a separately manufactured auxiliary tool equipped with a support rod at a predetermined position on the bottom body. can be manufactured.

In particular, if the upper end of the auxiliary tool is regulated by the bottom wall of the double vacuum bottle and the lower end is regulated by the bottom body as in the example, the manufacturing process for fixing the auxiliary tool is simple and durable. I can do it.
