Description

[Detailed Description of the Invention] The present invention relates to a stainless steel charm bottle.

Conventional magic bottles contain a medium bottle made of a vacuum double bottle made of glass, and have the disadvantage that if the magic bottle is dropped, the medium bottle easily breaks.

Therefore, a stainless steel magic bottle is provided in which the outer case and the inner bottle are made of stainless steel, and the space between them is sealed to form a vacuum chamber, thereby preventing the inner bottle from being damaged. There is.

By the way, even in the stainless steel magic bottle mentioned above,
Since the middle bottle is only welded at the exterior and mouth, the middle bottle becomes cantilevered, so that if the magic bottle is dropped horizontally with the middle bottle filled with water, the shoulder of the exterior will fall. There was a problem that the inner bottle could hit the inner surface of the outer case due to plastic deformation or the welded part of the mouth part to come off.

This invention was created in view of the above problems, and it is a stainless steel magic bottle that regulates the horizontal displacement of the medium bottle, greatly improves its strength against drop impact, and prevents the drop in heat retention performance. The purpose is to provide.

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

The drawing shows a stainless steel magic bottle according to the present invention,
1 is a stainless steel body plate that makes up the body of the exterior, 2 is a stainless steel shoulder plate that makes up the shoulder, 3 is a stainless steel medium bottle with argon welded to the shoulder plate 2 and the mouth, and 4 is an internally insulated bottle. A stopper body houses a material 5, 6 is a cap, and 7 is an outer lid.

A plurality of protrusions 1a are provided on the inner surface of the lower part of the body plate 1 by press working, and these protrusions 1a are attached to the inner surface of the middle bottle 3.
The outer surface of the lower part faces the outer surface of the lower part with a predetermined gap δ.

This gap δ is determined so that when the medium bottle 3 is displaced in the left-right (horizontal) direction, the distortion of the mouth of the medium bottle 3 or the shoulder plate 2 is within the elastic limit.

Therefore, when hot water is contained in the medium bottle 3, the heat is not conducted to the protruding portion 1a due to the gap δ, and a decrease in heat retention performance can be minimized.

The lower end of the body plate 1 is bent outward, and the lower end and the upper end of a stainless steel bottom plate 8 constituting the bottom of the exterior are argon welded.

A tip tube 9 made of a steel pipe is fixed to the central lower surface of the bottom plate 8, and a bottom cover 10 made of synthetic resin is fitted around the bottom plate 8.

The tip tube 9 communicates the outside air with the vacuum chamber 11 formed between the body plate 1, the inner bottle 3, and the bottom plate 8, and is crimped and cut after the air removal from the vacuum chamber 11 is completed. It is sealed.

In this type of magic bottle, when the medium bottle 3 is dropped with water filled, it tends to be particularly vulnerable to horizontal drops.

In other words, since the medium bottle 3 is in a so-called cantilevered state with respect to the exterior, a large bending stress acts on the mouth of the medium bottle 3 and the shoulder plate 2, which may cause the welded part of the mouth of the medium bottle 3 to come off or cause the shoulder plate to break off. This is because the plate 2 is easily plastically deformed.

By the way, in the present invention, since the protruding part 1a is provided on the inner surface of the body plate 1, the inner bottle 3 is supported at both ends in an elastically deformed state by the welded mouth part and the protruding part 1a. , the lateral wobbling of the medium bottle 3 is minimized, and there is no fear that the welded portion will come off or the shoulder plate 2 will be deformed.

In the above embodiment, a plurality of protrusions 1a were provided by press working on the inner surface of the shell plate 1 constituting the body of the exterior, but an annular protrusion was provided on the entire circumference of the inner surface of the shell plate 1. Good too.

As is clear from the above explanation, according to the present invention, a protrusion that protrudes in the direction of the medium bottle is provided on the body of the exterior, and this protrusion restricts the displacement of the medium bottle to a predetermined amount or less. Therefore, even if a horizontal drop impact is applied to the magic bottle filled with water, the deformation of the mouth and shoulder of the medium bottle can be kept within the elastic limit.

In addition, in normal conditions, a predetermined gap is provided between the protrusion and the body of the inner bottle or outer package, so that heat conduction is prevented and there is no fear that the heat retention performance will deteriorate.

Furthermore, in this type of magic book, atmospheric pressure is applied to the exterior, and when an external force acts on the exterior, it creates a large impact with the addition of the atmospheric pressure, but a protrusion is formed on the body and the exterior Because it is reinforced, it can withstand large impact forces.

This reinforcing effect is greater when the protrusion is annular.

In addition, since the outer packaging is generally made of a thicker material than the medium bottle from the viewpoint of strength, there is no risk of breakage during the formation of the protrusion, and the processability is good.

In addition, since the medium bottle does not have any protruding parts, the inner surface is smooth and easy to clean, and the fluid does not accumulate locally and there is no risk of corrosion. can be easily processed even when puffing or plating.

As described above, in the present invention, since the protrusion is simply formed on the body without providing any separate parts, it is possible to reduce the cost and obtain many of the advantages described above.
