Description

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

A portable thermos bottle is made of metal, generally made of stainless steel, with the outer body of the vacuum double bottle exposed and omitted, and a shoulder body A and a top B attached to the top as shown in Fig. 4. A bottom body C is attached to the lower end, and a support rod D ₁ for the strap is placed opposite the shoulder body A.
A support rod D ₂ is provided in a protruding manner, and a support rod D ₃ is made to project from the _bottom body C directly below one of the support rods D 2 so that it can be hung both vertically and horizontally.

The bottom body of this kind of thermos bottle does not support the inner bottle like the inner bottle made of glass, but on the contrary, it supports the vacuum double bottle and supports the exhaust chip formed at the bottom of the vacuum double bottle. It has functions such as protection and stability when placed.

Therefore, the bottom body is usually simply force-fitted or glued onto the vacuum double bottle. However, if the saucer-shaped bottom body is simply force-fitted,
There is a possibility that it may rotate accidentally or fall off due to impact, and those that use adhesive have the disadvantage of poor assembly workability.

In addition, since the support rod for the strap protrudes from the bottom body, it has the disadvantage that it can easily be damaged by hitting other objects when dropped or hung in a vertical position, and can easily catch on clothing.

In view of these points, the present invention has a bottom body with a double-fitting type inside and outside, which prevents the bottom body from moving or falling off, and also includes a support for the lanyard in a recess made in a part of the bottom body. The above-mentioned drawbacks have been solved by providing a rod so that it does not protrude outside the vessel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The portable thermos bottle of the present invention will be described below with reference to the accompanying drawings, which are examples thereof.

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.
At the same time as screwing the cap 4 onto the vacuum double bottle 1.
A bottom body 5 is fitted to the lower end of the holder.

As shown in FIGS. 2 and 3, this bottom body 5 is composed of an inner base body 6 and an outer base body 7, and the inner base body 6 protrudes downward from the outer wall 1a of the metal vacuum double bottle. The outer sole body 7 is fitted onto the inner surface of the short cylindrical portion 8 formed in this manner, and the outer sole body 7 is fitted onto the outer surface of the short cylindrical portion 8 to form a double inner and outer structure. In other words, the short cylindrical portion 8 is sandwiched between the inner sole body 6 and the outer sole body 7. .

The inner bottom body 6 has a substantially funnel shape as a whole, and the tip 1b of the vacuum double bottle 1 is located in the center. Also,
A support rod 9 for a lanyard is provided protruding downward from the funnel-shaped slope.

On the other hand, a recess 10 is formed in the outer sole 7 by recessing a portion corresponding to the support rod 9 of the inner sole, and the support rod is inserted through a window hole 12 formed in the top wall 11 of the recess. 9 projects into the recess 10.

The support rod 9 is composed of a pair of left and right leg rods 9a and a pin 9b, and the leg rods 9a fit into grooves 14 carved in the side wall 13 of the recess 10, so that the two are firmly fixed. It is set as.

Further, an annular protrusion 15 is formed on the short cylinder part 8 of the vacuum double bottle 1, and a concave line 16 is provided on the inner surface of the outer bottom body 7.
The fitting is made tighter.

In addition, in the drawings, reference numeral 17 denotes a notch provided at the top of the inner bottom body 6, which fits into a convex portion (not shown) formed around the bottom of the vacuum double bottle to prevent rotation; is a cylindrical bottle holder located at the center of the outer bottom body and protruding upward. This bottle receiver 18 is fitted into the squeeze tube 19 of the inner bottom body 6 and is placed close to the bottom surface of the vacuum double bottle 1, so that when a thermos bottle is dropped, for example, the bottom body is subjected to impact deformation. It is designed to support the bottom of a double vacuum bottle in case of a vacuum bottle.

According to the portable thermos bottle of the present invention, the bottom body can be easily assembled by simply fitting the inner and outer bottom bodies in sequence. Furthermore, after assembly, the short cylindrical part of the vacuum double bottle is sandwiched between the inner and outer bottom bodies, so if it is dropped or bumped, for example, the bottom body will receive an impactful unidirectional force. There is no fear that the bottom body will fall off due to deformation even if the bottom body acts.

In addition, the support rod for the lanyard on the bottom body used for horizontal hanging is located in a recess in the bottom body and does not protrude outside the vessel, making it not only aesthetically pleasing but also easy to carry. It will not get in the way or be damaged by bumping into it. In particular, if the leg rods are fitted into the outer sole body as in the embodiment, it is extremely durable.

Furthermore, since the bottom body is fitted into the short cylindrical part of the vacuum double-bottomed bottle both inside and outside, water will not enter the bottom body, making it sanitary and less likely to malfunction. I can do it.
