Description

試験管のような円筒容器は垂直に立てた状態で保管したり移動したりする必要があり、そのために、例えば特許文献1や特許文献2に記載されるような専用のスタンドが用いられている。また、化学実験等において試験管内に貯留した溶液の容量を計量することが必要な場合には、別途、ピペット等を用いて試験管内の溶液を取り出して計量するか、当初から計量目盛り付き試験管をスタンドに垂直に立てた状態で、溶液を貯留することが行われる。さらに、試験管内の溶液の性状あるいは反応等をスタンドに垂直に立てた静置の状態で観察する場合は、肉眼的に、またはルーペを用いて観察している。   A cylindrical container such as a test tube needs to be stored or moved in a vertically standing state. For this purpose, a dedicated stand as described in, for example, Patent Document 1 or Patent Document 2 is used. . In addition, when it is necessary to measure the volume of the solution stored in the test tube in a chemical experiment, etc., the solution in the test tube is taken out and measured separately using a pipette or the like, or a test tube with a measuring scale from the beginning. The solution is stored in a state where the stand is vertically set on the stand. Furthermore, when observing the property or reaction of the solution in the test tube in a standing state standing vertically to the stand, the observation is made visually or with a loupe.

計量コップに規定量の液体を注入できるようにしたスタンド兼計量具が特許文献3に記載されている。これは、スタンドの水平な主体部に計量コップを静置できる凹陥部を設けておき、該凹陥部に計量コップを置き、凹陥部の上周縁位置まで液体を注入すれば、規定量だけの溶液を計量できるというものである。   Patent Document 3 describes a stand / metering device that can inject a specified amount of liquid into a measuring cup. This is because if a concave part where the measuring cup can be placed still is provided in the horizontal main part of the stand, the measuring cup is placed in the concave part and the liquid is injected up to the upper peripheral position of the concave part, a solution of a prescribed amount can be obtained. Can be measured.

上記のように、従来の試験管スタンドは、もっぱら試験管を垂直に立てた姿勢で安定的に保持・保管することを目的としており、試験管内に貯留した溶液の計量または溶液の観察については、格別の配慮がなされていないので、計量を必要とするときには、ピペットや計量目盛り付き試験管等の別個な手段を必要とする。特許文献3に記載のスタンド兼計量具は、計量コップの保持と収容する溶液の計量を同時に行えるものであるが、予め規定した1つの液量を計量するだけのものであり、化学実験等において逐次貯留されていく溶液の液量変化や性状等を経時的に観察することはできない。また、いずれのものも、精緻に観察しようとすると、ルーペのような拡大手段が必要となる。   As described above, the conventional test tube stand is intended to stably hold and store the test tube in a vertically upright posture. Since no special consideration has been given, when measuring is required, separate means such as a pipette or a measuring tube with a measuring scale are required. The stand and measuring instrument described in Patent Document 3 can hold the measuring cup and measure the solution to be stored at the same time, but only measures a predetermined amount of liquid. It is impossible to observe the change in liquid volume, the properties, etc. of the sequentially stored solution over time. In addition, in order to observe precisely any of them, a magnifying means such as a loupe is required.

本発明は、上記のような事情に鑑みてなされたものであり、容器に貯留される溶液等の容量や性状を拡大した状態で随時計量および観察することができるスタンドを兼ねた計量具を提供することを目的とする。   The present invention has been made in view of the circumstances as described above, and provides a measuring instrument that also serves as a watch and a stand that can be observed in a state where the volume and properties of a solution or the like stored in a container are enlarged. The purpose is to do.

本発明によるスタンド兼計量具は、全体が透明な円筒体本体と、該円筒体本体の中央に形成された縦穴と、該縦穴の内面に形成された目盛りとを有することを特徴とする。   A stand and measuring instrument according to the present invention is characterized by having a cylindrical body that is entirely transparent, a vertical hole formed in the center of the cylindrical body, and a scale formed on the inner surface of the vertical hole.

本発明によるスタンド兼計量具において、円筒体本体は中央に縦穴を有しており、使用時に、そこに、計量すべき溶液を貯留する貯留容器が安定的に差し込まれる。すなわち、円筒体本体および縦穴は貯留容器に対するスタンドとして機能する。また、円筒体本体は全体が透明であり、レンズ現象を奏するので、縦穴に挿入した貯留容器および貯留された溶液に対して、側面視では拡大鏡として機能する。そのために、見る者は溶液等に対する精緻な観察が可能となる。また、縦穴には目盛りが付されており、その目盛りを読むことにより、貯留容器に貯留される溶液等の容量を随時計量することができる。すなわち、円筒体本体は拡大鏡付きの計量具としても機能する。   In the stand / metering device according to the present invention, the cylindrical body has a vertical hole in the center, and a storage container for storing a solution to be weighed is stably inserted into the cylinder body in use. That is, the cylindrical body and the vertical hole function as a stand for the storage container. Further, since the entire cylindrical body is transparent and exhibits a lens phenomenon, it functions as a magnifying glass in a side view with respect to the storage container inserted in the vertical hole and the stored solution. Therefore, the viewer can observe the solution or the like precisely. Moreover, the vertical hole is provided with a scale, and by reading the scale, the volume of the solution or the like stored in the storage container can be adjusted as needed. That is, the cylindrical body also functions as a measuring instrument with a magnifying glass.

上記のように、本発明によるスタンド兼計量具は、それ単独で、スタンドと拡大鏡付き計量具としての双方の機能を奏することができ、実用上高い利便性を備える。   As described above, the stand and measuring instrument according to the present invention can function as both a stand and a measuring instrument with a magnifying glass by itself, and has practically high convenience.

本発明において、円筒体本体を構成する材料は透明な材料であればよく、透明なガラス材料、透明な樹脂材料等が用いられる。透明なガラス材料としては、耐熱ガラス、硼珪酸ガラス等を例として挙げることができ、透明な樹脂材料としては、アクリル樹脂等を例として挙げることができる。素材が軽量物でありスタンドとして所要の安定性が得られない場合には、円筒体本体の底面に金属板のような加重材を取り付けてもよい。   In the present invention, the material constituting the cylindrical body may be a transparent material, and a transparent glass material, a transparent resin material, or the like is used. Examples of the transparent glass material include heat-resistant glass and borosilicate glass, and examples of the transparent resin material include acrylic resin. In the case where the material is light and the required stability cannot be obtained as a stand, a weight material such as a metal plate may be attached to the bottom surface of the cylindrical body.

円筒体本体の中央に形成される縦穴の直径は、貯留容器を安定的に支持できるよう、使用する貯留容器の直径に応じて適宜設定する。円筒体本体の高さと縦穴の深さも、使用する貯留容器の高さと、そこにどの程度の量の溶液を貯留するかを考慮して適宜設定する。縦穴の内面に形成する目盛りは、どの程度の精緻さで溶液の容量を計測するかに応じて適宜設定すればよい。   The diameter of the vertical hole formed in the center of the cylindrical body is appropriately set according to the diameter of the storage container to be used so that the storage container can be stably supported. The height of the cylindrical body and the depth of the vertical hole are also set as appropriate in consideration of the height of the storage container to be used and how much solution is stored therein. The scale formed on the inner surface of the vertical hole may be set as appropriate depending on how precise the volume of the solution is to be measured.

本発明によるスタンド兼計量具が対象とする前記貯留容器は、それが透明な容器であることを条件に特に制限はなく、化学実験等で使用される試験管は最も好適であるが、調剤や料理の材料等を収容する貯留容器であってもよい。   The storage container targeted by the stand and measuring instrument according to the present invention is not particularly limited as long as it is a transparent container, and test tubes used in chemical experiments are most suitable. It may be a storage container for storing cooking ingredients and the like.

本発明によるスタンド兼計量具は、試験管内に貯留する溶液等に対して、それ単独で、スタンドと拡大鏡付き計量具としての双方の機能を奏することができ、実用上高い利便性を備える。   The stand / metering device according to the present invention can perform both functions as a stand and a measuring device with a magnifying glass alone with respect to a solution or the like stored in a test tube, and has practically high convenience.

以下、添付の図面を参照しながら、本発明を実施の形態に基づき説明する。図1は本発明によるスタンド兼計量具の一例を貯留容器の一例と共に示す斜視図であり、図2は本発明によるスタンド兼計量具の1つの具体的な使用例を示す斜視図である。   Hereinafter, the present invention will be described based on embodiments with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of a stand / metering tool according to the present invention together with an example of a storage container, and FIG. 2 is a perspective view showing one specific use example of the stand / metering tool according to the present invention.

図1に示す例において、本発明によるスタンド兼計量具Aは透明なアクリル樹脂で作られた円筒体本体1を有し、該円筒体本体1の中央部には断面円形である縦穴2が形成され、縦穴2の内周面には目盛り3が形成されている。Bは貯留容器の一例であり、計量しようとする溶液Cを貯留するための透明な試験管である。この試験管Bを垂直に立てた状態で静置できるように、縦穴2の直径と深さが設定されている。   In the example shown in FIG. 1, a stand / meter A according to the present invention has a cylindrical body 1 made of a transparent acrylic resin, and a vertical hole 2 having a circular cross section is formed at the center of the cylindrical body 1. A scale 3 is formed on the inner peripheral surface of the vertical hole 2. B is an example of a storage container, and is a transparent test tube for storing the solution C to be weighed. The diameter and depth of the vertical hole 2 are set so that the test tube B can be left standing in a vertical state.

スタンド兼計量具Aの使用に際し、溶液Cを貯留する透明な試験管Bを縦穴2内に差し込む。その姿勢で試験管Bは垂直状態で静置され、円筒体本体1は試験管Bに対するスタンドとして機能する。また、円筒体本体1は透明であり、側面視でレンズ効果を奏する。そのために、円筒体本体1を側面から見ることにより、見る者は、試験管Bおよびそこに貯留されている溶液Cを拡大して見ることができる。また、縦穴2には目盛り3が付してあり、溶液の容量も正確に計量することができる。なお、図1で4は、縦穴2と目盛り3が拡大されて見える状態を模式的に示している。   When the stand / meter A is used, a transparent test tube B storing the solution C is inserted into the vertical hole 2. In this posture, the test tube B is allowed to stand in a vertical state, and the cylindrical body 1 functions as a stand for the test tube B. Moreover, the cylindrical body 1 is transparent and has a lens effect in a side view. Therefore, by viewing the cylindrical body 1 from the side, the viewer can enlarge and view the test tube B and the solution C stored therein. Further, the vertical hole 2 is provided with a scale 3, so that the volume of the solution can be accurately measured. In addition, 4 in FIG. 1 has shown typically the state which the vertical hole 2 and the scale 3 appear expanded.

図2は、図1に示すスタンド兼計量具Aを、例えば再公表特許WO01/067064公報に開示されるような、従来知られた実験動物の搾乳装置の一部に使用した場合を示している。図2において、Bは透明な試験管である集乳容器であり、密封栓11により密封された状態で、円筒体本体1の前記縦穴2に差し込まれている。   FIG. 2 shows a case where the stand / meter A shown in FIG. 1 is used in a part of a conventionally known experimental animal milking apparatus as disclosed in, for example, the republished patent WO01 / 067064. . In FIG. 2, B is a milk collection container which is a transparent test tube, and is inserted into the vertical hole 2 of the cylindrical body 1 while being sealed by a sealing plug 11.

密封栓11には第1のミルクチューブ12および第2のミルクチューブ13の一端が集乳容器B内に連通する状態で挿入されている。第1のミルクチューブ12の他端には、従来知られたティートカップ14が交換可能な状態で装着され、また、第2のミルクチューブ13の他端側は、反復して陰圧と大気圧を発生させる負圧源(不図示)に接続している。なお、この負圧源に係る構成は前記再公表特許WO01/067064公報に詳しく記載される。   One end of the first milk tube 12 and the second milk tube 13 is inserted into the sealing stopper 11 in a state of communicating with the milk collection container B. A conventionally known teat cup 14 is attached to the other end of the first milk tube 12 in a replaceable state, and the other end side of the second milk tube 13 is repeatedly subjected to negative pressure and atmospheric pressure. Is connected to a negative pressure source (not shown). The configuration relating to the negative pressure source is described in detail in the republished patent WO01 / 067064.

円筒体本体1には適宜の支持アーム15が取り付けてあり、該支持アーム15の先端には第1のミルクチューブ12のティートカップ14近傍がホルダー16を介して支持されている。   A suitable support arm 15 is attached to the cylindrical body 1, and the teat cup 14 vicinity of the first milk tube 12 is supported via a holder 16 at the tip of the support arm 15.

搾乳に当たり、搾乳しようとする実験動物(不図示)をスタンド兼計量具Aの近くに置き、実験者は、実験動物の乳頭位置にティートカップ14を移動させ、実験動物の乳頭に密着させる。そして、図示しない負圧源を駆動する。それにより、実験動物からの搾乳が開始する。搾乳された母乳は、ティートカップ14および第1のミルクチューブ12を通って、透明な集乳容器B内に集乳される。この装置において、スタンド兼計量具Aは前記のように拡大鏡としての機能を果たすので、実験者はスタンド兼計量具Aを側面視することにより、搾乳の過程を通して集乳容器B内の容量(搾乳量)および性状をはっきりと計量および観察することができる。なお、図2にも、縦穴2と目盛り3が拡大されて見える状態を模式的に符号4で示している。   In milking, an experimental animal (not shown) to be milked is placed near the stand / meter A, and the experimenter moves the teat cup 14 to the nipple position of the experimental animal and closely contacts the nipple of the experimental animal. Then, a negative pressure source (not shown) is driven. Thereby, milking from the experimental animal starts. Milked milk is collected in a transparent milk collection container B through the teat cup 14 and the first milk tube 12. In this apparatus, since the stand / metering tool A functions as a magnifying glass as described above, the experimenter looks at the stand / metering tool A from the side, so that the capacity in the milk collection container B (through the milking process) Milking amount) and properties can be clearly measured and observed. In FIG. 2 as well, a state in which the vertical hole 2 and the scale 3 appear to be enlarged is schematically indicated by reference numeral 4.
