【考案の詳細な説明】 (イ)産業上の利用分野 本考案は，湿式化学分析をはじめとする種々の化学分野
に用いられるメスフラスコの固定器具に関するものであ
る。[Detailed Description of the Invention] (a) Field of Industrial Use The present invention relates to a fixture for a measuring flask used in various chemical fields including wet chemical analysis.
(ロ)従来技術 湿式化学分析をはじめとする溶液化学の分野において用
いられるガラス器具の中で，メスフラスコは定容量測定
のためには欠くことの出来ない器具であり，常に大量に
使用されている。(B) Prior art Among the glass instruments used in the field of solution chemistry including wet chemical analysis, the volumetric flask is an indispensable instrument for constant volume measurement, and is always used in large quantities. There is.
しかしながら，その形状は第３図に示すように，定量精
度を高めるために細長い首部４を持っている。この為，
一般には第４図に示すような二重構造を持つ受け皿５な
どが用いられている。なお，１は受け皿の開口部を示
す。However, as shown in FIG. 3, its shape has an elongated neck portion 4 in order to enhance the accuracy of quantification. Therefore,
Generally, a tray 5 having a double structure as shown in FIG. 4 is used. In addition, 1 shows the opening of the tray.
(ハ)考案が解決しようとする問題点 第３図の形状は，頭部が重くなり，非常にバランスが悪
くなっている。特に，溶液を満たさないときは，非常に
倒れ易い。(C) Problems to be solved by the device The shape of Fig. 3 has a heavy head and is extremely unbalanced. Especially when the solution is not filled, it easily falls.
しかし，第４図は上部の開口部１がメスフラスコの最大
径に合わせて造られており，完全に固定することが出来
ない。更に，複数の設置部を持つため，メスフラスコの
使用本数に対する柔軟性にかけている。However, in FIG. 4, the upper opening 1 is made to fit the maximum diameter of the volumetric flask and cannot be completely fixed. Furthermore, because it has multiple installation parts, it is not flexible enough for the number of volumetric flasks used.
(ニ)問題点を解決するための手段 本考案の固定器具は，メスフラスコの側面及び下部をゴ
ムで支えることを特徴とする。(D) Means for solving the problem The fixing device of the present invention is characterized in that the side surface and the lower portion of the volumetric flask are supported by rubber.
(ホ)作用 本考案は，メスフラスコの圧入時に発生する真空層によ
り二重に固定作用が働き，離脱時は，メスフラスコを傾
けるだけで，これを簡単におこなう。(E) Action In the present invention, the vacuum layer generated at the time of press-fitting the volumetric flask has a double fixing action, and at the time of detachment, this can be easily done by tilting the volumetric flask.
(ヘ)実施例 本考案の一実施例を図面に基づいて説明する。(F) Embodiment An embodiment of the present invention will be described with reference to the drawings.
第１図における２は，メスフラスコ下部に設置された弾
性部材（例えばゴム製）の固定器具である。2 in FIG. 1 is a fixing device for an elastic member (for example, made of rubber) installed at the bottom of the volumetric flask.
このゴム製の固定器具にメスフラスコを垂直に押し込
む。固定器具の垂直壁部分３をメスフラスコの最大径を
持つ部分６より高くすると，ゴムの弾性により強く固定
される。Push the volumetric flask vertically into this rubber fixture. When the vertical wall portion 3 of the fixing device is made higher than the portion 6 having the maximum diameter of the volumetric flask, it is strongly fixed due to the elasticity of rubber.
また，メスフラスコの底面と固定器具とにより囲まれる
部分の空気が押し出され，ゴムに特有の弾性によりこの
部分は減圧状態となり，上部からの大気圧の作用により
さらにメスフラスコを強く固定することが出来る。In addition, the air in the part surrounded by the bottom of the volumetric flask and the fixture is pushed out, and this part is in a decompressed state due to the elasticity peculiar to rubber, and the volumetric flask can be further strongly fixed by the action of atmospheric pressure from above. I can.
離脱は，メスフラスコの側面が球面及び底面が平面とい
う構造により，メスフラスコを固定器具に対し４５度程
傾斜させる（第２図）と，減圧部が簡単に大気に開放さ
れ，また，ゴムの弾性がメスフラスコの球部分を押し出
すように作用するため，簡単に離脱出来る。なお，垂直
壁部分３としては，図示のようにその断面が上方の肉厚
を薄く形成しておけば，メスフラスコの固定器具に対す
る固定，離脱操作が簡単に行える。To separate the structure, the side surface of the volumetric flask is a spherical surface and the bottom surface is a flat surface. When the volumetric flask is tilted about 45 degrees with respect to the fixture (Fig. 2), the decompression unit is easily opened to the atmosphere and the rubber The elasticity acts to push out the spherical portion of the volumetric flask, so it can be easily removed. As shown in the figure, if the vertical wall portion 3 is formed so that its cross-section has a thin upper wall, the operation of fixing and removing the measuring flask from the fixing device can be easily performed.
(ト)効果 本考案により，メスフラスコを一本ずつ固定することが
可能となり，転倒などの事故を防ぐとともに，メスフラ
スコ個々の使用のため設置効率の向上を図る事ができ
る。また，材料としてゴムを利用しているため，極めて
経済的である。(G) Effect The present invention makes it possible to fix volumetric flasks one by one, prevent accidents such as tipping over, and improve the installation efficiency because individual volumetric flasks are used. Moreover, since rubber is used as a material, it is extremely economical.
さらに，固定器具の重量が不足し，より安定化が要求さ
れる場合は，ゴムの底部に鉛などの錘を埋め込んでもよ
い。Further, when the weight of the fixing device is insufficient and more stabilization is required, a weight such as lead may be embedded in the bottom of the rubber.
第１図は，本考案の一実施例を示し，メスフスコを固定
した状態であり，第２図は，離脱を示す。 第３図は，メスフラスコの形状を示し，第４図は，従来
技術の受け皿の一実施例である。 ２ ゴム製固定器具FIG. 1 shows an embodiment of the present invention, in which the Mesfusco is fixed, and FIG. 2 shows detachment. FIG. 3 shows the shape of a volumetric flask, and FIG. 4 shows an embodiment of a conventional receiving tray. 2 rubber fixtures
