Description

DETAILED DESCRIPTION OF THE INVENTION The present 'Jt' J, I relates to a method for manufacturing a two-day vacuum double bottle in which reeds are used as an inner bottle for 9 liters, and in particular, the upper part is used as an ice jar, etc. The present invention relates to a method for manufacturing a double-breasted vacuum bottle of the wide-mouth bottle type, the opening of which has the same diameter as the body.

The vacuum double bottle used as the inner bottle of the conventional 'E11') bottle was provided with an injection spout only at the top. However, the requirement has come to include a 9-inch bottle that is injected from the top and dispensed from the bottom, and a 1-9 bottle that is equipped with a full liquid volume meter. :il 1
．． 'Double-ended vacuum double-bottle bottles with one bottle have become more and more necessary.

For example, Japanese Patent Publication No. 8B-5340 discloses a method for manufacturing double-sided vacuum bottles with openings at the top and bottom, as described in 1'1 below.
Is there a method shown in which two cylinders, the inner and outer cylinders that have been fully reduced in diameter are superimposed, and the upper and lower ends are welded to make them double-tight? It has the disadvantage that it cannot be made sufficiently small in diameter compared to 1. Also, Publication No. 87-1194 discloses a method of forming an inner bottle and an outer bottle by welding the large diameter ends of bottle bodies made of 1φ and blown so that one side has the same diameter as the body and the other side has a smaller diameter. has been done. However, in method C, because two separately blown bottle bodies are butted together, it is extremely difficult to match them accurately due to distortion of the bottle body, unevenness of the diameter, unevenness of the wall thickness, etc. It is. Furthermore, Japanese Patent Publication No. Sho 50-25391 discloses a method for manufacturing double-ended double-ended vacuum bottles, but in the double-ended vacuum bottles obtained by this method, the bottom part is a single glass tube. Therefore, the protection as a vacuum double pin '9. ')J's results are not sufficient. In addition, in these conventional methods, the shape of the bottle body, which is the material for the inner bottle and the outer bottle, is different from that of a general vacuum double-bottle bottle, so a special shaped bottle body is blown in advance. Moreover, since the manufacturing process was different from the manufacturing process for general vacuum two-car bottles, it was impossible to put it on a normal manufacturing line, and a significant increase in costs was unavoidable.

This book was developed in view of the above circumstances, and uses valves that are commonly used in the past.
“Slight changes to k 7Jl] by adding up and down υ
It is the sole object of this invention to provide a method for manufacturing double-ended vacuum bottles with J neck ligatures. The double bottle 1 consists of an inner bottle la and an outer bottle 1b, and has a cylindrical body 2, and an upper opening 8 at the upper end of the body 2.
is open. On the other hand, a bottom part 4 is formed in the lower part of the body part 2, and a lower eye tube 5 is protruded from the center of the bottom part 4, and the lower eye tube 5 is connected to a lower mouth part 6 which communicates with the inside of the vacuum double bottle l. is open. The inner bottle llL and the outer bottle 1b are spaced apart from each other by a slight gap 7'fr: body part 2a+2J bottom part 4a+4.
biI&'Hini lower mouth inner g5a and lower mouth outer tube 5b are form 5!
, and l1lThi E52 &, 2 b (D upper end and lower end of inner W51L and lower ITJ outer g5 b are joined at joints 8 and 9. lO is outer bottle l
This is an exhaust pipe provided at a position R9 of the bottom 4b of the exhaust pipe, and after exhausting the air in the gap 7, it is sealed by melting, and the inside of the gap 7 is maintained in a vacuum.

No. 21 No. 1 shows an example of the method of the present invention step by step. First, the most important process is the inner bottle (ii)
ii Shows Ll degree. In this process, the inner bottle valve lla'i is shown. The inner bottle valve IIIL is the inner bottle valve IIIL.
It consists of a body part 2a and a bottom part 5a, and a surplus part 12 extends from the upper part of the body part 21L. Note that this surplus portion 12 is completely unnecessary for the inner bottle 1a, but it is an indispensable portion when blowing the inner bottle la into a 5Y shape.
It is molded integrally with the inner bottle Ia. This also applies to the surplus portion of the outer bottle described here.

In this specification, a product with an integrally attached surplus part is called a "valve", and a product with the surplus part separated is called a "bottle". Therefore, this inner bottle] Kurubutt
ai, t, is exactly the same as the inner bottle pulp used in the production of conventional wide-mouth vacuum double bottles.

First, in process B, the inner bottle valve 11! Bottom part 4a of L
At the center of the lower opening ``#51L'' (r) is welded and the lower U inner tube 5ai is communicated with the inner bottle pulp lla.

Note that this step B can be performed in the same way as the step of attaching the exhaust pipe to the outer cap of a conventional vacuum double bottle. Next, in step C, the inner bottle valve 11
! Place the upper part of the body 2a of L in a predetermined position and cutter 1.
3, remove the excess portion 12'i and make the inner bottle IIL:
([- is formed.Next, in the step 1j (a plurality of asbestos spacers 14' (r) (usually 3 places) are adhered to the part 4a. This completes the inner bottle preparation process,
The inner bottle la is completed. In addition, this inner bottle preparation process A-
The order of the individual steps within D is not particularly limited, and may be rearranged as appropriate.

Next, HH indicates the outer bottle preparation process. E indicates the outer bottle valve 1lb, which is slightly louder than the inner bottle valve 112L. A surplus portion 12 extends from the upper portion of the body portion 2b. This outer bottle valve Ilb is exactly the same as the outer bottle valve used in the production of ordinary wide-mouth daily strain vacuum double bottles. Facing it, first go down to the center of the Jjishu S4b and weld the bottom outer tube 5b (A): Y) bottle valve t.
tb. This process is performed in the lower mouth of the inner bottle valve IIIL mentioned above. This can be done in the same way as installing g5a. Next, in step O, the exhaust pipe 10 is welded to the eccentric position of the bottom portion 4b, and the exhaust pipe 10 is communicated with the outer bottle valve Llb. Next, in work 8H, the upper part of the body 2b is k 7? The cutter 13 is used to cut the excess portion 122. (The outer bottle 1b is removed and the outer bottle 1b is formed. With this, the outer bottle preparation process is completed and the outer bottle 1b is completed.

In this outer bottle preparation process R-H, the order of the individual processes is not limited (i'J, etc.) and can be changed. For example, after cutting the body part 2b, It is also possible to attach the pipe 5b and the exhaust pipe 10'i.
This is No. i1. However, if the entire large-diameter body is IJJfOr, the cut part is extremely soft and easily deformed, so the valve is difficult to handle and is likely to be damaged or the cut part deformed. Preferably, the turning process is performed in line 9 at the end of the outer shell preparation step IC-H. In this respect, the bp is exactly the same in the inner bottle preparation steps A to D. Further, the exhaust pipe IO may be provided at an angle with respect to the center 4Q;1 of the outer bottle valve 1b as shown in the direction, but it is preferable to provide it parallel to this. This facilitates the operation 1'F in the subsequent process, but if it is mounted perpendicularly to the surface of the bottom 4b of the outer bottle valve Ilb by tilting it, the strength of the joint will be increased.

Inner bottle? 1. The Hachibi process Mo D and the outer bottle preparation process E-H have no relation to each other and are performed completely separately and in parallel. And the internal pressure obtained by these steps
a and outer bottle lb are the outer bottle Ib in the setting process.
Inner bottles 1a'6'' are housed in the inner bottle and are combined and assembled. At this time, it is better to turn the inner bottles la and outer bottles Ib upside down. That is, first, turn the inner bottles 1&k (411 upright and turn them upside down). Support the bottom part 4a from 1 and set it, and insert the nuclear bottle 1a.
At the same time, the lower inner tube 5a is inserted into the lower outer tube 5b. Then it is an outer bottle)
is supported on the inner bottle via the asbestos spacer 14.

Next, the set inner bottle la and outer bottle it) move to the welding process J-M at this step 1\. First, in step J, the bodies 2a, 2b of the inner bottle la and the outer bottle lb)
: The ends (lower ends in an inverted state) are completely heated and softened, bent in a direction toward each other, and temporarily welded. Next, in step K, while pressing the temporarily welded part against the mold 15, a small amount of air is pressurized into the l'Lfl gap 7K between the inner bottle Ia and the outer bottle lb, and the upper ends of the bodies 2a+2b of the inner bottles Ha and lb are sealed. Complete welding is performed and the joint 8 is molded. Next, in a step, the inner lower opening W5a and the lower outer outer W5b are welded again at their tips to form nine joints. Note that the order of welding the joints 8!9 is not limited to the above order, but may be reversed.

Through the above process, we have an inner bottle la and an outer bottle lb as shown in M! 77I:! A double bottle with 3.6 openings at the top and bottom, in which the gap 7 is sealed except for the exhaust pipe IO, is obtained.

The following is a glass plate that has been slowly cooled according to the usual method to remove distortion of the glass.
Plating solution is injected from the exhaust pipe IO to fully plate the outer surface of inner bottle l & and the inner surface of outer bottle lb, and after removing the plating solution, the inner bottle L is washed with water and dried.
11 between a and outer bottle lb? , j Exhaust the air in 7 to create a gap? The inside is evacuated and the bottle is evacuated and sealed to obtain a vacuum double bottle 1 as shown in the fused seal.

The method of the present invention is limited to the method of the above-mentioned embodiment.
j can. For example, in "Jitsuiyo", the upper ends of the bodies 2a+2b of the inner bottle la and the outer cover lb are bent and welded by a welder Yanagi, but either the inner bottle 1a or the outer cover Ib or both are bent. It is also possible to bend the upper end of the body part in the 11h1 process to form the entire flange, and then weld this in the welding process to form 8 joints.
oJ is Noh. Furthermore, in the actual btu example, d, and A
The size of the gap 7 between y l a and the outer bottle Ik) is regulated with an asbestos spacer 14 according to the standard method, or the gap 7 is controlled by setting the positional relationship between the lower inner pipe 5a and the lower outer pipe 5b. As a result, there is no need to use an asbestos spacer in this combination, and it is possible to obtain a two-day vacuum knee bottle with extremely excellent heat retention ability.

In addition, in FIG. 2, the valve 11a in each process,
Although llb, bottles la, and lbi are all written upward, this does not necessarily indicate the orientation of the valve or bottle in the process. Therefore, in each step, the workpiece may be processed upside down or laid down on its side, if necessary. For example, as described above, it is preferable to perform the sectional process and welding process J-M in an inverted state as shown in row 9, and furthermore, it is preferable to perform the process in the exhaust pipe installation and process Gz in an inclined state.

In the present invention, the valves 111L and 111b, which are the materials of the inner bottle 1a and the outer bottle 1b, can be used as bulbs for manufacturing vacuum double bottles of the one-mouth wide-mouth bottle type commonly used in the past. Since a special type of valve is not used, it can be manufactured at a lower cost than the conventionally known two-day vacuum double bottle. In addition, in the manufacturing process 17, only the steps of attaching the lower inner tube 5a and the lower outer tube 5b and welding the two are added to the normal vacuum double bottle manufacturing process. These processes are 7111■ processes that are similar to the normal exhaust gas mounting process and mouth welding process, and do not require any particularly complicated processes, and only require slight modifications to the processing equipment as necessary. Therefore, according to the present invention, the cost can be significantly reduced compared to the known method.

Also, both days vacuum double bottle l manufactured by the method of unexploded 9J
Since a lower opening pipe 5 is formed in the bottom part 4, a separate appropriate pipe can be connected here, and the content liquid can be poured out through the chain pipe, and a branch pipe can also be connected. By connecting it to the Keliquid Co., Ltd., the amount of liquid inside can be visually checked from the outside. Moreover, this double vacuum bottle 1 has a lower opening tube 5 (11) of a vacuum double bottle, so it has excellent heat retention ability.

Furthermore, in the present invention, a separate -FLJ inner tube 5a and a lower mouth outer tube 5b2 are attached to the inner portions 4a and 4b of the bottle 1a+1b, so the diameters of the H fire tubes 5a and 5b can be changed freely. The diameter of the EJ is determined by making it thicker than the diameter of the EJ. Therefore, the pipes connected thereto should be made as small as possible to minimize heat leakage.
