【考案の詳細な説明】
本考案は両口まほうびん、詳しくはガラス製内
瓶と外瓶とを口部と底部とで溶着し、内外瓶の間

るものである。[Detailed description of the invention] This invention is a double-ended magic bottle, more specifically, an inner bottle made of glass and an outer bottle are welded together at the mouth and the bottom, and the space between the inner and outer bottles is made into a vacuum chamber. This invention relates to a double-ended magic bottle having openings formed at the mouth and the bottom.
従来、両口まほうびんを製造する段階におい
て、口部と底部とを溶着し、これを空冷すると
き、口部あるいは底部の溶着箇所が割れるという
事故が多発しており、そのため一般に両口まほう

は、溶着時には内外瓶が1200℃程度の高温に熱せ
られ、内外瓶ともに膨張するが、これを空冷する
とき、表面積が大きくかつ冷えやすい外瓶の方が
内瓶より大きく収縮し、この収縮差が溶着箇所に
集中するからである。 Conventionally, during the manufacturing process of double-ended magic bottles, when the mouth and bottom were welded together and air-cooled, there were many accidents where the welded parts of the mouth or bottom broke, and as a result, it was common practice to Hobins are said to be lacking in mass production. The reason for this is that during welding, the inner and outer bottles are heated to a high temperature of about 1200℃, causing both the inner and outer bottles to expand. However, when they are air-cooled, the outer bottle, which has a larger surface area and is easier to cool, contracts more than the inner bottle. This is because the shrinkage difference is concentrated at the welding location.
また、内外瓶の間の空間を真空にするとき、真
空歪が内外瓶のアール部分に集中し、これが残留
歪となつてまほうびんの強度低下の原因ともなつ
ている。 Furthermore, when the space between the inner and outer bottles is evacuated, vacuum strain concentrates on the rounded portions of the inner and outer bottles, which becomes residual strain and causes a decrease in the strength of the magic bottle.
本考案はかかる従来の欠点に鑑みてなされたも
ので、製造段階における溶着箇所の割れを防止す
るとともに、真空歪を吸収して強度低下を防止し
た両口まほうびんを提供することを目的とする。 The present invention has been made in view of these conventional drawbacks, and the purpose is to provide a double-ended magic bottle that prevents cracking at the welded parts during the manufacturing stage and absorbs vacuum strain to prevent a decrease in strength. do.
以下、本考案を一実施例である添付図面にした
がつて説明する。 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.
図面は本考案にかかる両口まほうびんの一例を

ている。なお、９はチツプ管である。 The drawing shows an example of a double-ended magic bottle according to the present invention, 1 is an inner bottle made of glass, 2 is an outer bottle made of glass, and these inner and outer bottles are welded at a mouth part 3 and a bottom part 4, The space between is used as a vacuum chamber 5, and
Openings 6 and 7 are formed in the mouth portion 3 and the bottom portion 4, respectively. In the middle part of the side surface of the inner bottle 1, an uneven part 8 having a wave-shaped longitudinal section is continuously formed around the entire circumference. Note that 9 is a chip tube.

ほうびんを完成する。 The method for manufacturing the double-ended magic bottle having the above structure is almost the same as the conventional method. That is, the inner bottle 1 having openings at the mouth and the bottom is inserted from the mouth side of the outer bottle 2, and the inner bottle 1 and the outer bottle 2 are welded at the bottom, and the inner bottle 1 and the outer bottle 2 are welded together at the bottom. Weld while squeezing the opening. After the thus welded inner and outer bottles are air-cooled to 400°C to 500°C, they are placed in an annealing furnace and annealed. After that, plating liquid is poured into the tip tube 9 to plate the outer surface of the inner bottle 1 and the inner surface of the outer bottle 2, and the air between the inner and outer bottles is removed from the tip tube 9 to create a vacuum. By sealing 9, the double-ended magic bottle is completed.

しての機械的強度を向上させることができる。 Due to the difference in the amount of shrinkage between the inner and outer bottles during air cooling,
A large stress (compression on the inner bottle side, tension on the outer bottle side) occurs at the welded part of the mouth 3 or bottom 4, especially the welded part with a smaller cross-sectional area (bottom side in the drawing)
are prone to cracking and cracking. However, since the inner bottle 1 is provided with the uneven portion 8, the stress is absorbed by the cushioning properties of the uneven portion 8, and no cracks or cracks occur at the welded portion. Also,
When creating a vacuum between the inner and outer bottles, the rounded parts 10 and 11
Vacuum strain will be concentrated at , but this strain will also be absorbed by the uneven portion 8 and no residual strain will remain in the rounded portions 10 and 11. Therefore, the mechanical strength of the magic bottle as a whole can be improved.

よい。 In the above embodiment, the inner bottle is provided with an uneven portion, but the outer bottle or both the inner bottle and the outer bottle may be provided with an uneven portion. Further, the uneven portion may be continuous at one place or may be divided into two or more places, and the uneven portion may be provided not only in the middle part of the side surface but also in the vicinity of the mouth or the bottom, or in the rounded part. Further, the uneven portion is not limited to a bellows shape, but may be a spiral shape, and the wave shape may be any triangular wave, sine wave, or the like.
以上の説明で明らかなように、本考案によれ

されていた両口まほうびんを量産することが可能
となる。 As is clear from the above explanation, according to the present invention, at least one of the inner and outer bottles of the double-ended magic bottle is provided with an uneven part having a wave-like longitudinal section. The unevenness absorbs the difference in the amount of shrinkage between the bottle and the bottle, thereby preventing cracks and cracks at the welded area. Therefore, it becomes possible to mass-produce double-ended magic bottles, which were conventionally considered to be unsuitable for mass production.
また、上記凹凸部は、空気抜き取り時の真空歪
