ところで、上記の内瓶の製造方法A,B,Cには、各々次の
ような問題がある。By the way, each of the above-mentioned inner bottle manufacturing methods A, B, and C has the following problems.
すなわち、第４図に示した製造方法Ａでは、首部および
シール部の径と貯留胴部の径との比が大きくなると加工
が不可能になる。That is, in the manufacturing method A shown in FIG. 4, when the ratio of the diameter of the neck portion and the seal portion to the diameter of the storage barrel portion becomes large, processing becomes impossible.
また、第５図に示した製造方法Ｂでは、工程（ａ）の絞
り加工においてその絞り率に制限があるため、小径部の
径が大きく、またその高さが低いものしか得ることがで
きず、したがって首部の熱伝導を少なくするために同首
部の高さを高くすることが困難である。さらに、この製
造方法Ｂでは、加工の途中に焼鈍工程等を加えることに
より上記の問題を解決できるが、その場合には上記の熱
鈍工程等が加わることによりコストが上がる。Further, in the manufacturing method B shown in FIG. 5, since the drawing rate is limited in the drawing process in the step (a), only the small diameter portion having a large diameter and the height thereof being low can be obtained. Therefore, it is difficult to increase the height of the neck in order to reduce heat conduction in the neck. Further, in the manufacturing method B, the above problem can be solved by adding an annealing step or the like in the middle of processing, but in that case, the cost increases due to the addition of the thermal annealing step or the like.
また、第６図に示した製造方法Ｃでは、シール部に溶接
部分があるため第３図に示した栓部３のパッキン3aとの
密着性が十分でなく、このため内瓶４の貯留部８の内部
の気密が不十分になるという心配がある。さらに、この
製造方法では、工程（ｃ）の溶接を行う場合に溶接部分
の左右にそれぞれ適宜な長さの直管部が必要であり、こ
のためシール部が必要以上に長くなることがある。Further, in the manufacturing method C shown in FIG. 6, since there is a welded portion in the seal portion, the close contact with the packing 3a of the plug portion 3 shown in FIG. There is a concern that the airtightness inside 8 will be insufficient. Furthermore, in this manufacturing method, when performing the welding in the step (c), straight pipe portions of appropriate lengths are required on the left and right sides of the welded portion, and therefore the seal portion may become longer than necessary.
さらに、一般に魔法瓶の性能を左右するのは首部（口
部）よりの熱伝導に下る熱損失を如何にするかであり、
上記製造方法A,Bでは、首部およびシール部を一体に成
形しているため、首部の熱伝導を少なくするために同首
部の板厚を他の部分より薄くすることができず熱損失の
点で問題であった。Furthermore, it is generally the heat loss from the neck (mouth) that affects the performance of the thermos,
In the above manufacturing methods A and B, since the neck portion and the seal portion are integrally molded, the plate thickness of the neck portion cannot be made thinner than the other portions in order to reduce the heat conduction of the neck portion, and the point of heat loss. Was a problem.
そこで、この発明の内瓶の製造方法では、略円筒状の貯
留部と、この貯留部の上部開口部に位置する小径円筒状
の直筒部とを一体に形成し、次に上記直筒部の上端に同
直筒部と略同径の首部を突き合わせて溶接し、その後上
記直筒部に内方に突出する段部を形成し、さらに上記首
部の板厚を予め上記直筒部の板厚よりも薄くすることに
よって上記の問題点を解決するとともに作業性の改善を
図ったものである。Therefore, in the method for manufacturing an inner bottle of the present invention, a substantially cylindrical storage portion and a small-diameter cylindrical straight tubular portion located at the upper opening of the storage portion are integrally formed, and then the upper end of the straight tubular portion is formed. A neck portion having substantially the same diameter as that of the straight cylinder portion is butted and welded, and then a step portion projecting inward is formed in the straight cylinder portion, and the plate thickness of the neck portion is made thinner than the plate thickness of the straight cylinder portion in advance. By doing so, the above problems are solved and workability is improved.

ものである。FIG. 1 is a diagram showing a process chart of a method G for manufacturing an inner bottle of a metal thermos bottle according to the present invention. Hereinafter, the manufacturing method G will be described in detail with reference to FIG. In the following description, expressions such as “upper” and “lower” refer to “upper” and “lower” in the drawings.
（ａ）まず、板厚0.4mmのSUS304の素板に絞り加工を施
して、略半球面状の貯留部29と、その上部に位置し、か
つ上方に突出する有蓋円筒状で小径の直筒部30とからな
る椀状の一体成形物を成形する。(A) First, a 0.4 mm thick SUS304 base plate is subjected to a drawing process to form a substantially hemispherical storage portion 29, and a cylindrical cylindrical portion with a small diameter, which is located above the storage portion 29 and projects upward. A bowl-shaped integrally molded product composed of 30 and 30 is molded.
（ｂ）次に、上記直筒部30の上端部を切断して同直筒部
30の上部を開口する。(B) Next, the upper end of the straight tubular portion 30 is cut to cut the straight tubular portion.
Open the top of 30.
（ｃ）肉厚0.3mmのSUS304のパイプで上記直筒部の内径
と同一の内径を有するものを所定の長さに切断して首部
31とする。ここで、首部30を成形する場合には、他に例

よって成形してもよい。(C) A SUS304 pipe with a wall thickness of 0.3 mm, which has the same inner diameter as that of the straight cylindrical portion, is cut into a predetermined length and the neck portion is cut.
31. Here, when the neck portion 30 is formed, it may be formed by, for example, drawing a SUS304 blank plate having a plate thickness of 0.3 mm.
（ｄ）上記工程（ａ），（ｂ）で成形した貯留胴部29と

成形した首部31の下端を突き合わし、かつ第２図に示す
ように直筒部30の内壁面と首部31の内壁面とを面一に一
致させて溶接する。(D) The lower end of the neck portion 31 formed in the step (c) is butted against the upper end of the integrally formed product including the storage barrel portion 29 and the straight tube portion 30 formed in the steps (a) and (b), and As shown in FIG. 2, the inner wall surface of the straight tube portion 30 and the inner wall surface of the neck portion 31 are flush with each other and welded.
（ｅ）上記の溶接箇所の下部の直筒部30にスピニング加
工等を施すことによってシール部32を形成する。(E) The sealing portion 32 is formed by subjecting the straight cylindrical portion 30 below the welded portion to a spinning process or the like.
（ｆ）別に底部を略半径状に絞って成形した肉厚約0.4m
mの貯留底部33の上端を、上記貯留胴部29の下端に溶接
して一体にし、内瓶Ｈを形成する。(F) Separately, the bottom is squeezed into a substantially radial shape and the wall thickness is about 0.4 m
The upper end of the storage bottom portion 33 of m is welded to the lower end of the storage barrel portion 29 to be integrated with each other to form the inner bottle H.
このような内瓶の製造方法Ｇにあっては、首部およびシ

ることができる。In the method G for manufacturing such an inner bottle, processing is possible even if the ratio of the diameter of the neck portion and the seal portion to the diameter of the storage barrel portion is large, and the neck portion is manufactured to have an arbitrary height. Moreover, since the seal portion is not welded, a seal portion having a smooth inner surface can be obtained. Further, in the manufacturing method G, since the wall thickness of the neck is smaller than the wall thicknesses of the storage body and the seal portion, heat conduction in the neck portion can be suppressed to be low. Therefore, the strength of the storage body and the seal portion can be reduced. The heat retention effect of the thermos can be improved without dropping.

発生が全く無かった。In addition, a thermos bottle manufactured by using the inner bottle molded by the manufacturing method G and an inner bottle molded by the conventional manufacturing methods A, B, C in the same shape and the same size as the inner bottle manufactured by the above manufacturing method G. As a result of carrying out a practical test for one month with the thermos produced by using the thermos, no difference was found in the heat retaining effect between these thermos. After the practical test, the thermos was disassembled, the inner bottle was taken out, and the appearance was inspected. There were no abnormalities such as tears.

保温効果の向上を図ることができる。As described above, the method of manufacturing the inner bottle of the metal thermos bottle of the present invention integrally includes a substantially cylindrical storage barrel portion and a small-diameter cylindrical straight cylinder portion located at the upper opening of the storage barrel portion. Formed, and then the upper end of the straight cylindrical portion is welded by abutting a neck portion having substantially the same diameter as the straight cylindrical portion, and then a step portion projecting inward is formed in the straight cylindrical portion. It can be processed even if the ratio of the diameter of the neck and seal of the inner bottle to the diameter of the storage barrel is large, and the neck can be manufactured at any height, and welding at the seal does not occur. Since this is not done, it is possible to obtain a seal portion having a smooth inner surface.
Furthermore, in this method of manufacturing an inner bottle, the thickness of the neck portion is made thinner than the thickness of the storage body portion and the seal portion to improve the heat retaining effect of the thermos bottle without reducing the strength of the storage body portion and the seal portion. Can be planned.
