Description

[Detailed Description of the Invention] ν Field of Application The present invention provides a novel structure of a vacuum double bottle used as an inner bottle for magic bottles, etc., and a WA manufacturing method for the new vacuum double bottle. It concerns a method for

Conventional technology The vacuum double bottle commonly used in the past has an outer cap,
It consists of an inner pin housed in an outer nuclear bottle, and the outer pin and inner bottle are integrally joined at the periphery of the upper opening, and the inner surface of the outer bottle and the outer surface of the inner bottle are plated with silver. , and the gap between the outer pin and the inner bottle is maintained in a vacuum.

Therefore, when manufacturing this vacuum double bottle, after forming a double bottle with an outer pin and an inner bottle, a vacuum is applied to the outer bottle in order to create a vacuum between the outer pin and the inner bottle of the double bottle. An exhaust pipe is attached, and the air in the gap between the outer pin and the inner bottle is evacuated from the exhaust pipe to create a vacuum in the gap and then melt-sealed to maintain the vacuum. The exhaust pipe is usually provided at the bottom of the vacuum double bottle.

Various methods have been adopted to manufacture this vacuum double bottle, but for example, in a vacuum double bottle, there is a surplus at the end of the upper opening of the inner bottle. An inner bottle valve with an extended part is blown, and the excess part of the silver-white bottle valve is cut off to form an inner pin.Meanwhile, the excess part is removed at the end of the upper opening of the outer bottle in the vacuum double bottle. An extended-shaped outer bottle valve is blown, a glass thin tube is welded to the center of the bottom of the outer bottle valve, and this is communicated with the outer bottle valve to form an exhaust pipe, and the surplus of the outer bottle valve is The upper half and lower half of the outer bottle are formed by cutting out the body and the upper half of the outer bottle.The inner bottle is placed inside the lower half of the outer bottle, and the upper half of the outer bottle is placed on top of the inner bottle. The upper and lower halves of the bottle are welded together, and the outer pin and the upper opening of the inner bottle are welded and joined together, and then the plating liquid is poured from the exhaust pipe into the space between the outer pin and the inner bottle. A method is adopted in which the inner surface of the outer pin and the outer surface of the inner bottle are injected with silver plating, and then the air in the gap between the outer pin and the inner bottle is exhausted from the exhaust pipe, and the exhaust pipe is melt-sealed.

Note that the surplus parts of the outer bottle valve and inner bottle valve in the above explanation are completely unnecessary parts for vacuum double bottles, but are essential parts for manufacturing each valve, and these valves are normally used. Supplied with attached. Therefore, also in this specification, the valve is described as having a redundant portion.

Further, in this specification, a product having these surplus portions is referred to as a "bulb", and a product with the surplus portion removed is referred to as a "bottle".

Problems to be Solved by the Invention However, in the vacuum double bottle as described above, an exhaust pipe is protruded from the bottom of the vacuum double bottle, and the height of the vacuum double bottle is increased by the length of the exhaust pipe. becomes higher. The length of the exhaust pipe is usually about 2.5 to 3 cm, and several centimeters of space is required at the bottom of a liquid container such as a magic bottle just to accommodate this exhaust pipe.

Therefore, the space for this exhaust pipe is completely meaningless space for the magic bottle's function as a liquid container, and it is necessary to remove the exhaust pipe from the bottom of the vacuum double bottle. For example, the magic bottle can be made smaller by a few CIs without changing its content, making it extremely compact.

Similarly, with the outer bottle valve 10a tilted upright, the stopper 45 is fitted into the opening, the exhaust pipe installation position is heated, air is blown into the outer bottle valve 10a from the air supply pipe 46, and the heated portion is heated. You can make a hole by blowing it out.

In this invention, after cutting the outer bottle valve 10a at its neck 4a and body 2a, the outer bottle 1a is cut off.
It is also possible to drill holes in the shoulder 3a of the upper half of the body.

! So this outer bottle 1a
The upper half 30 and lower half 31 and the inner bottle prepared in exactly the same manner as described in the inner bottle preparation step in the second invention are assembled in an assembly step. This assembly process is basically the same as that described in the second invention, but the outer bottle 1a
Since the exhaust pipe 9 is not provided in the hole, in the step of forming the joint 8 between the outer bottle 1a and the inner bottle 1b in step I, a suitable air blowing nozzle is fitted into the hole to blow air into the hole. It is necessary to mold the joint part 8.

A glass thin tube 15 is welded to the hole of the double bottle thus obtained to form an exhaust pipe 9.

To weld the glass capillary tube 15 to a double bottle, the double bottle is held in a rotating support W34 similar to that shown in FIG. While making the glass thin! F15 is brought into contact with the periphery of the hole, and the contact portion is heated by the burner nozzle 29 to weld.

Effect of time and light According to the vacuum double bottle of the present invention, since the exhaust pipe 9 is not provided protruding from the bottom of the vacuum double bottle, extra space is not required at the bottom of the vacuum double bottle in the magic bottle. First, it can be made into an extremely compact magic book with a low height without reducing the internal capacity. Further, according to the present invention, the exhaust pipe 9 is provided protruding from the shoulder 3 of the vacuum double bottle, but normally a magic bottle has a considerable space formed above the shoulder of the vacuum double bottle. Since the exhaust pipe 9 of the present invention is housed within that space, it has no effect on the shape or dimensions of the magic bottle.

In addition, in general, magic bottles are screwed onto the bottom of the vacuum double bottle to tighten the vacuum double bottle, and the vacuum double bottle is held between the top and bottom by the tightening body and the outer periphery of the upper opening. However, since the vacuum double bottle of the present invention has almost no distortion at the bottom, there is no risk of the vacuum double bottle being damaged by over-tightening the clamping body.

Further, according to the second to fifth inventions of the present application, the novel vacuum double bottle as described above can be manufactured. In addition, the valves used in these methods can be exactly the same as the valves conventionally used in the production of general vacuum double-bottomed bottles, and no special irregularly shaped valves are used. Moreover, the vacuum double bottle manufacturing process can be easily applied to a conventional vacuum double bottle manufacturing apparatus, thereby avoiding an increase in cost.

Furthermore, in the normal vacuum double bottle manufacturing process, the glass capillary tube 15 is welded while rotating the outer bottle valve tOa or the outer bottle 1a as described above, but the vacuum double bottle of the present invention has a shoulder part. Since the glass capillary tube 15 is welded to the glass tube 15, it is difficult to apply the conventional method as it is. In the methods of the inventions of the present application, this problem has been solved and the vacuum double bottle having the exhaust 79 on the shoulder 3 has been successfully manufactured at a cost of ¥FJm.

In the second invention, the air supply pipe 27 is connected to the outer bottle valve 10.
Inserted into a. To solve the problem that the outer bottle valve 10a cannot be rotated up to t, the burner nozzle 29 can be rotated by horizontally rotating the air pipe 27, and the outer bottle valve 10a can be rotated outward along the tip periphery of the glass capillary tube 15 without rotating the outer bottle valve 10a. The bottle bulb 10a can be heated and the glass capillary tube 15 can be properly welded and communicated with the outer bottle bulb 10a to form the exhaust pipe 9 at the shoulder.

Further, in the third invention, before welding the glass capillary tube 15 to the outer bottle bulb 10a and making it communicate, the body 2a and the neck 4a of the outer bottle bulb 10a are cut, and the upper half of the cut outer bottle 1a is Since the glass capillary tube 15 is welded to the part 30 and communicated with it, the operation is extremely simple, and almost all the equipment for manufacturing conventional vacuum double bottles can be used as is.

Furthermore, in the second invention, since the burner nozzle 29 is inserted into the outer bottle valve 10a, the inside of the outer bottle valve 10a tends to become deficient in oxygen, and it is necessary to supply air to the burner nozzle 29. However, the fourth invention According to , such problems do not occur because the heating is done from the outside.

Further, in the fifth invention, since the exhaust pipe 9 is not attached during the process of assembling the outer bottle 1a and the inner bottle 1b to form a double bottle, the exhaust pipe 9 does not get in the way during the assembly process. effective.
