【発明の詳細な説明】
〈産業上の利用分野〉
本発明は、保温・保冷に用いる真空二重容器、いわゆる
魔法瓶と総称されるものに関するものである。 主とし

に限定されるものでは無い。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to vacuum double containers used for heat/cold preservation, generally referred to as so-called thermos flasks. Although it is mainly used at home on a daily basis, there are no particular limitations on where it is used or what it is used for.
〈従来の技術〉
従来用いられている真空二重容器、いわゆる魔法瓶はガ

を構成し、然る後二重壁内の空気を抜いて真空二重容器
、即ち魔法瓶としたものである。<Prior art> Conventionally used vacuum double containers, so-called thermos flasks, are made by processing glass or stainless steel to form a double container, and then the air inside the double wall is removed to create a vacuum double container. , that is, a thermos flask.
〈発明が解決しようとする問題点〉

コスト高であった。<Problems to be Solved by the Invention> When these conventional products are made of glass, they are easily broken and there are inherent limitations in shaping, and when made of stainless steel, they are extremely expensive.
そこで、本発明者は割れに＜＜、造形が自由で、コスト
の安い真空二重層を開発したのである。Therefore, the inventors of the present invention have developed a vacuum double layer that is free from cracks, can be shaped freely, and is inexpensive.
く問題を解決するための手段〉
その解決手段は、主としてプラスチックを以て二重容器
を形成し、それに排気機構を備え、二重壁内の空気を排
気機構によって排気して真空に成る様にしたものである
。The solution is to form a double container mainly made of plastic, equip it with an exhaust mechanism, and create a vacuum by evacuating the air inside the double wall with the exhaust mechanism. It is.
〈作用〉
プラスチックは比較的に造形が自由で、しかもコストが
低いと言う利点が有る。 その反面、現在の処、「空気

う真空二重容器にとって好ましからざる欠点がある。<Function> Plastics have the advantage of being relatively flexible in shaping and low cost. On the other hand, the current vacuum double container has disadvantages such as ``1, which allows air to pass through it and has poor gas barrier properties,'' which is undesirable.
しかしながら現在、魔法瓶の実用保温・保冷時間はせい
ぽい８時間未満である。 と、言う事は逆に言えば８時
間程、真空を保っておれば真空二重容器としての役目を
果たす事が出来るのである。However, currently, the practical heat/cold retention time of a thermos flask is less than 8 hours. In other words, if the vacuum is maintained for about 8 hours, it can function as a vacuum double container.
然らば、プラスデックで形成しても本発明のごとく真空
二重容器に排気機構を備え、ニュ重壁内を随時真空に出

ある。Therefore, even if the container is made of plus deck, it can be put to practical use if the vacuum double container is equipped with an exhaust mechanism and the inside of the double wall can be evacuated at any time as in the present invention.

術によって、容易に製造する事が出来る１、 そして、
プラスチ・ツクの内、比較的ガスバリヤ−特性の良い（

、電動を問わず利用する事が出来る。<Effects of the Invention> Such a vacuum double container equipped with an exhaust mechanism mainly made of plastic deck can be easily manufactured using general molding machines, processing machines, and manufacturing techniques1.
Among plastics, it has relatively good gas barrier properties (
For example, if a material such as nylon, polyester, acrylic, or vinylidene chloride is molded singly or in multiple layers, it is easy to maintain the vacuum for 8 hours. In other words, at the start of each use, the exhaust mechanism creates a vacuum inside the double wall, providing practical heat retention and
Even if the degree of vacuum decreases after 8 hours of cold storage time, the vacuum can be restored the next time it is used. The exhaust mechanism can be used either manually or electrically.
プラスチックで形成すると言う事は、コストが低い事と
、自由な造形、即ちガラス・ステンレススチールに対し

が出来るのである〈実施例〉
図面に従い実施の態様を説明する。The fact that it is made of plastic means that the cost is low and that it can be shaped freely, that is, the size and shape can be arbitrarily selected to a degree that is incomparable to glass and stainless steel. (Example) Embodiments will be described according to the drawings.

It consists of And these are mainly formed with plus decks.

が出来るのである。In such a case, 1) After 8 hours, which is the normal practical heat retention time, the degree of vacuum gradually decreases due to the air permeability of plastic (air comes in) and the heat retention ability decreases. However, there is no problem at all in practical use. Moreover, the next time you use it, you can operate the exhaust pump again to evacuate the air inside the double wall and create a vacuum, so you can use it repeatedly.
