(57) [Summary] [Purpose] To provide a vacuum container for sample storage, such as a sample for an electron microscope, which can be easily prevented from oxidation and can be carried. [Structure] A sample 9 taken out from an electron microscope is put in a container 1 by opening a lid 2, the lid 2 is closed, and a vacuum container for sample storage is set in a leaked camera chamber 10 of the electron microscope. Next, the evacuation of the camera room 10 is started. As the degree of vacuum in the camera chamber 10 increases, the pressure difference inside and outside the container increases. Therefore, the stopper 5 is pushed from below, and when the pushing force exceeds the pushing force of the spring 4 by the spring 4, the stopper 5 rises. Therefore, a gap is created between the stopper 5 and the lid 2, and the inside of the container is evacuated by the opening O. When the pressure difference between the inside and the outside of the container disappears, the force of the spring 4 pushes down the stopper 5 again. next,
The camera chamber 10 is leaked, the camera chamber 10 is opened, and the vacuum container for sample storage is taken out. Even if the vacuum container for sample storage is exposed to the atmosphere, the inside of the container is vacuum-sealed by the O-rings 6 and 7, so that the sample 9 is stored in vacuum and oxidation is prevented.

【実施例】 図1は本考案の一実施例の断面図を示したものである。図において 、1は試料を入れるための気密を維持し得る容器、2は開口部Oを有する蓋であ る。3は開口Pを有するバネ当てで、このバネ当て3にはバネ4の一端が固定さ れている。5はバネ4の他端が固定された弁体となる栓で、この栓5はバネ4の 力で蓋2に押し当てられている。6,7はOリング、8は容器内部に大気を導く 際に栓5を開けるためのテコ体、9は試料である。Embodiment FIG. 1 is a sectional view showing an embodiment of the present invention. In the figure, 1 is a container capable of maintaining airtightness for containing a sample, and 2 is a lid having an opening O. Reference numeral 3 is a spring pad having an opening P, and one end of a spring 4 is fixed to the spring pad 3. Reference numeral 5 denotes a stopper that serves as a valve body to which the other end of the spring 4 is fixed. The stopper 5 is pressed against the lid 2 by the force of the spring 4. Reference numerals 6 and 7 are O-rings, 8 is a lever body for opening the stopper 5 when introducing the atmosphere into the container, and 9 is a sample.

【0007】 以下、図1に示した試料保存用真空容器へ電子顕微鏡用試料を保存する場合に ついて詳細に説明する。Hereinafter, the case of storing an electron microscope sample in the sample storage vacuum container shown in FIG. 1 will be described in detail.

【0008】 先ず、電子顕微鏡から取り出した試料9を蓋2を開けて容器1の中に入れる。 次に、蓋2を閉め、試料保存用真空容器を例えば電子顕微鏡のリークされたカメ ラ室10にセットする(図2参照)。カメラ室10への試料保存用真空容器のセ ットが終了すると、カメラ室10の真空引きを始める。カメラ室10の真空度が 上がるに従い、容器内外の圧力差は大きくなっていく。この為、栓5は下から押 され、この押す力がバネ4が栓5を押す力を越えたとき、栓5は上がる(図3参 照)。この為、栓5と蓋2の間に隙間ができ、開孔部Oにより容器内が真空に引 かれる。そして、容器内外の圧力差が無くなるとバネ4の力で栓5は再び押し下 げられる(図4参照)。次に、カメラ室10をリークしてカメラ室10を開け試 料保存用真空容器を取り出す。試料保存用真空容器を大気に晒してもOリング6 ,7により容器中は真空シールされるので、試料9は真空中に保存され酸化は防 止される。また、試料を容器から取り出す場合は、テコ体8で容器中をリークし 、蓋2を開ける。First, the sample 2 taken out from the electron microscope is put into the container 1 with the lid 2 opened. Next, the lid 2 is closed, and the vacuum container for sample storage is set in, for example, the leaked camera chamber 10 of the electron microscope (see FIG. 2). When the setting of the vacuum container for storing the sample in the camera chamber 10 is completed, the vacuuming of the camera chamber 10 is started. As the degree of vacuum in the camera chamber 10 increases, the pressure difference inside and outside the container increases. Therefore, the stopper 5 is pushed from below, and when the pushing force exceeds the pushing force of the spring 4 by the spring 4, the stopper 5 rises (see FIG. 3). Therefore, a gap is created between the stopper 5 and the lid 2, and the inside of the container is evacuated by the opening O. When the pressure difference between the inside and the outside of the container disappears, the stopper 5 pushes the plug 5 down again (see FIG. 4). Next, the camera room 10 is leaked, the camera room 10 is opened, and the vacuum container for storing the sample is taken out. Even if the vacuum container for sample storage is exposed to the atmosphere, the inside of the container is vacuum-sealed by the O-rings 6 and 7, so that the sample 9 is stored in vacuum and oxidation is prevented. When the sample is taken out from the container, the lever 8 is used to leak the inside of the container and the lid 2 is opened.

【0009】 尚、本考案は上記実施例に限定されない。上記実施例ではバネを設けたが、バ ネを設けずに重力により栓を蓋の開口にしてもよい。また、上記実施例では蓋を 設けたが、蓋に設けた開口より少し大きい開口を容器に設け、この開口を試料の 出し入れに兼用してもよい。The present invention is not limited to the above embodiment. Although the spring is provided in the above-mentioned embodiment, the stopper may be opened by gravity without using the bane. Further, although the lid is provided in the above embodiment, an opening slightly larger than the opening provided in the lid may be provided in the container, and this opening may also be used for loading and unloading the sample.

【0010】 また、上記実施例では、試料保存用真空容器を電子顕微鏡のカメラ室にセット したが、走査電子顕微鏡用試料を入れた容器であればこの走査電子顕微鏡の試料 室に、また、真空蒸着装置やイオンコーティング装置で用いられる材料を入れた 容器であればこれらの装置の排気室にセットすればよい。Further, in the above-mentioned embodiment, the vacuum container for sample storage is set in the camera room of the electron microscope. However, if the container for the sample for the scanning electron microscope is placed in the sample room of the scanning electron microscope, A container containing materials used in a vapor deposition device or an ion coating device may be set in the exhaust chamber of these devices.

【0011】[0011]

【考案の効果】 本考案の電子顕微鏡用試料などの試料保存用真空容器は、容器 を真空中に配置した際に容器内外の圧力差により駆動されて容器に設けられた開 口を開くように移動する弁体を有しているので、この容器を排気およびリーク手 段を有するチャンバーの中に入れるだけで容器内を真空にでき、この容器をチャ ンバーから取り出しても前記弁体により容器内は真空に保たれるので試料の酸化 を防止できる。この為、真空デシケーター装置やビニール特殊包装装置は不要で ある。また、本考案の試料保存用真空容器は小型なので持ち運びができる。EFFECTS OF THE INVENTION The vacuum container for storing a sample such as a sample for an electron microscope of the present invention is configured so that when the container is placed in a vacuum, the opening provided in the container is opened by being driven by the pressure difference between the inside and the outside of the container. Since it has a moving valve element, the inside of the container can be evacuated simply by putting it in a chamber that has exhaust and leak means. Is kept in a vacuum, preventing oxidation of the sample. Therefore, no vacuum desiccator device or vinyl special packaging device is required. Also, the vacuum container for sample storage of the present invention is small, so it can be carried.
