Abstract
Description
本発明は、食品試料の検査で検体を入れる試験管、バイアル、チューブ等の試料管を支持する試料管の支持具に関する。 The present invention relates to a sample tube support that supports a sample tube such as a test tube, a vial, or a tube into which a specimen is put in a food sample inspection.
従来、試験管などの薬用瓶を立てた状態で保持させる薬用瓶立てが知られている。
この薬用瓶立ては、包装箱の上面の保持板に薬用瓶を嵌合して起立状態に保持する嵌込孔を備え、この嵌込孔には保持板を放射状に切り込んだ切り込み片が設けられている。薬用瓶を嵌込孔に嵌め込むと、前記切り込み片がそれぞれ内側へ湾曲して瓶を外周から保持し、薬用瓶は、箱の底面との間で起立状態に保持される（特許文献１参照）。
Conventionally, a medicinal bottle stand that holds a medicinal bottle such as a test tube in an upright state is known.
This medicinal bottle stand is provided with a fitting hole for fitting the medicinal bottle to the holding plate on the upper surface of the packaging box and holding it in an upright state, and this fitting hole is provided with cut pieces obtained by radially cutting the holding plate. ing. When the medicinal bottle is fitted into the fitting hole, the cut pieces are curved inward to hold the bottle from the outer periphery, and the medicinal bottle is held in an upright state with the bottom surface of the box (see Patent Document 1). ).
しかしながら、上記従来の薬用瓶立ては、嵌込孔に嵌め込んだ薬用瓶と切り込み片との間に隙間がなく、嵌込孔から引き抜かれる薬用瓶には切り込み片から大きな抵抗がかかり、一方の手で薬用瓶を抜きながら他方の手で包装箱を押さえる必要があるなど、薬用瓶のスムースな抜取りができない。
本発明は、このような点に鑑みて、試料管の底面より大径な留め部に係止する貫通孔を板部材に穿設することで、試料管底部と板部材との隙間を確保して試料管の抜取りを容易にすると同時に、板部材を所定の板厚に形成して、貫通孔内で試料管が底面接地した姿勢から傾いても、試料管の底面縁が貫通孔内に当接して引っかかり、起立状態を保持できる試料管の支持具を提供することを目的とする。
However, the conventional medicinal bottle stand has no gap between the medicinal bottle fitted in the fitting hole and the cut piece, and the medicinal bottle pulled out from the fitting hole is subjected to great resistance from the cut piece. It is necessary to hold the packaging box with the other hand while pulling out the medicinal bottle by hand.
In view of such a point, the present invention secures a gap between the bottom of the sample tube and the plate member by drilling a through hole in the plate member that is locked to a fastening portion having a diameter larger than the bottom surface of the sample tube. This makes it easy to remove the sample tube, and at the same time, even if the plate member is formed to a predetermined plate thickness and the sample tube is tilted from the bottom-grounded position in the through-hole, the bottom edge of the sample tube contacts the through-hole. It is an object of the present invention to provide a sample tube support that can be caught in contact with and kept in an upright state.
本発明における課題解決のための具体的手段は、次の通りである。
第１に、接地底面４ａで自立可能で且つこの接地底面４ａより大径な留め部４ｂを高さ方向の中途部に備えた断面円形の試料管４を支持する試料管の支持具であって、
板部材２に前記試料管４の起立姿勢を支持する円形の貫通孔３が所定間隔ごとに複数穿設されていて、この貫通孔３に接地底面４ａ側から挿入された試料管４の留め部４ｂを貫通孔３の内周部で係止し、
前記板部材２は、前記貫通孔３内で試料管４が接地底面４ａ縁を支点Ｏとして傾いた場合にこの支点Ｏとは反対側の試料管４の接地底面４ａ縁が持ち上がって貫通孔３の内周壁に当接可能な板厚Ｗに形成されていることを特徴とする。
Specific means for solving the problems in the present invention are as follows.
First, there is provided a sample tube support that supports a sample tube 4 having a circular cross section, which can be self-supported on the ground bottom surface 4a and has a fastening portion 4b having a diameter larger than that of the ground bottom surface 4a in the middle of the height direction. ,
A plurality of circular through holes 3 for supporting the standing posture of the sample tube 4 are formed in the plate member 2 at predetermined intervals, and a fastening portion of the sample tube 4 inserted into the through hole 3 from the ground bottom surface 4a side. 4b is locked by the inner peripheral part of the through-hole 3,
In the plate member 2, when the sample tube 4 is inclined in the through hole 3 with the edge of the grounding bottom surface 4 a as a fulcrum O, the edge of the grounding bottom surface 4 a of the sample tube 4 on the side opposite to the fulcrum O is lifted. It is formed in the board thickness W which can contact | abut to the inner peripheral wall of this.
第２に、前記板部材２は、ウォーターバス５内で水浴可能な形状に且つ水に浮く素材で形成されていることを特徴とする。
第３に、前記貫通孔３は、前記板部材２の表面２ａ側に露出した孔径Ｓ１と裏面２ｂ側に露出した孔径Ｓ２とが同じ又は異なるように形成されていることを特徴とする。
第４に、前記板部材２は、前記試料管４の内底面４ｃを斜め上方から視認可能な板厚Ｗに形成されていることを特徴とする。
Second, the plate member 2 is formed in a shape that can be bathed in the water bath 5 and made of a material that floats on water.
Thirdly, the through hole 3 is formed such that the hole diameter S1 exposed on the front surface 2a side of the plate member 2 and the hole diameter S2 exposed on the back surface 2b side are the same or different.
Fourthly, the plate member 2 is characterized in that the inner bottom surface 4c of the sample tube 4 is formed to have a plate thickness W that can be seen obliquely from above.
これらの特徴により、試料管４の底面４ａより大径な留め部４ｂに係止する貫通孔３を板部材２に設けることで、貫通孔３の孔径Ｓは底面４ａより大径で且つ留め部４ｂより小径となって、試料管４底部と板部材２との隙間ｄを確保でき、片手での試料管４の引抜きが可能となるなど試料管４の抜取り容易化を図ると同時に、板部材２の板厚Ｗを、貫通孔３内の試料管４が底面４ａ縁を支点Ｏに傾くと支点Ｏ反対側の試料管４の底面４ａ縁が持ち上がって貫通孔３の内周壁に当接して引っかかり可能に形成することで、底面４ａで接地した姿勢（底面接地姿勢Ｔ）の試料管４が、斜めに傾いても起立状態を保持できる。 Due to these features, by providing the plate member 2 with the through hole 3 that engages with the fastening portion 4b having a larger diameter than the bottom surface 4a of the sample tube 4, the hole diameter S of the through hole 3 is larger than the bottom surface 4a and the fastening portion. The diameter of the sample tube 4 is smaller than that of the plate member 4 so that a gap d between the bottom of the sample tube 4 and the plate member 2 can be secured, and the sample tube 4 can be pulled out with one hand. When the sample tube 4 in the through hole 3 tilts the edge of the bottom surface 4a toward the fulcrum O, the bottom surface 4a edge of the sample tube 4 on the opposite side of the fulcrum O is lifted and abuts against the inner peripheral wall of the through hole 3. By being able to be caught, the sample tube 4 in a posture (bottom surface grounding posture T) grounded on the bottom surface 4a can maintain an upright state even when tilted obliquely.
さらに、円形の貫通孔３を所定間隔で複数穿設することで、断面円形の試料管４は傾いた起立姿勢（傾斜起立姿勢Ｋ）を維持したまま貫通孔３の周縁上を転がり（鉛直軸Ｊ回り
に首振り状に回転し）、試料管４に対し貫通孔３の周方向に沿って力がかかっても、この力を試料管４が首振り回転して逃がすことができ、ある試料管４が傾いて隣接する試料管４に当たっても、当てられた試料管４自体も首振り回転が可能であるため、各試料管４の起立状態（底面接地姿勢Ｔ及び傾斜起立姿勢Ｋ）が確実に保たれる。
Further, by making a plurality of circular through holes 3 at predetermined intervals, the sample tube 4 having a circular cross section rolls on the periphery of the through hole 3 while maintaining the tilted standing posture (tilted standing posture K) (vertical axis). Even if a force is applied to the sample tube 4 along the circumferential direction of the through-hole 3, the sample tube 4 can be swung to release the force. Even when the tube 4 tilts and hits the adjacent sample tube 4, the applied sample tube 4 itself can also swing and rotate, so that each sample tube 4 is in an upright state (bottom surface contact posture T and inclined upright posture K). To be kept.
好ましくは、板部材２をウォーターバス５内で水浴可能な形状に且つ水に浮く発泡プラスチック等の素材で形成してもよく、ウォーターバス５内の水面に浮かべた板部材２の貫通孔３に試料管４を留め部４ｂまで挿入して、水面上に試料管４を所定長さ露出させた状態を保持しながら、水面下を所定温度に保温できる。
さらには、貫通孔３の孔径Ｓを表裏面２ａ、２ｂで同じにすれば、製造の容易化が図られ、板部材２の表裏面２ａ、２ｂで孔径Ｓが異なる貫通孔３を穿設すれば、試料管４を板部材２の表面２ａから挿入した場合と、裏面２ｂから挿入した場合とで、貫通孔３の内周部と留め部４ｂとの係止位置が変わり、テーパ状の試料管４の場合には挿入深さを変えることができ、例えば、ウォーターバス５内の水浴時に水面上に露出する所定長さ等を選択可能となる。なお、貫通孔３の内周部とは、貫通孔３の内周壁及び表裏面２ａ、２ｂ側の内周縁を合わせた部分をいう。
Preferably, the plate member 2 may be formed in a shape that can be bathed in the water bath 5 and made of a material such as foamed plastic that floats on the water, and is formed in the through-hole 3 of the plate member 2 floating on the water surface in the water bath 5. The sample tube 4 can be inserted up to the retaining portion 4b to keep the surface below the water surface at a predetermined temperature while maintaining the state where the sample tube 4 is exposed for a predetermined length on the water surface.
Furthermore, if the hole diameter S of the through hole 3 is the same on the front and back surfaces 2a and 2b, the manufacturing is facilitated, and the through hole 3 having a different hole diameter S is formed on the front and back surfaces 2a and 2b of the plate member 2. For example, when the sample tube 4 is inserted from the front surface 2a of the plate member 2 and when it is inserted from the back surface 2b, the locking position of the inner peripheral portion of the through hole 3 and the fastening portion 4b changes, and the tapered sample is changed. In the case of the tube 4, the insertion depth can be changed. For example, a predetermined length exposed on the surface of the water in the water bath 5 can be selected. In addition, the inner peripheral part of the through-hole 3 means the part which match | combined the inner peripheral wall of the through-hole 3, and the inner peripheral edge of the front and back surfaces 2a and 2b side.
また、板部材２の板厚Ｗを、試料管４の内底面４ｃを斜め上方から視認可能に形成することも好適であって、起立状態の試料管４内の検体の量や色チェック等の状態確認ができる。 It is also preferable to form the plate thickness W of the plate member 2 so that the inner bottom surface 4c of the sample tube 4 can be viewed from obliquely above, such as checking the amount and color of the sample in the sample tube 4 in the standing state. You can check the status.
本発明に係る試料管の支持具によれば、試料管の底面より大径の留め部に係止可能な貫通孔が形成された板部材を、所定の板厚に形成することで、試料管の底部と貫通孔との隙間を形成できると同時に、試料管が傾いても底面縁が貫通孔内に引っかかって起立状態を保持できる。 According to the sample tube support according to the present invention, the plate member in which the through-hole that can be locked to the fastening portion having a diameter larger than the bottom surface of the sample tube is formed to have a predetermined plate thickness. A gap between the bottom and the through hole can be formed, and at the same time, even if the sample tube is tilted, the bottom edge is caught in the through hole and the standing state can be maintained.
以下、本発明の実施の形態を図面に基づいて説明する。
図１〜３には、本発明の第１実施形態に係る試料管の支持具１が示されている。
この支持具１は、接地底面４ａで自立する試料管４を支持する略矩形状の板部材２であって、この板部材２に、前記試料管４の起立状態を支持する貫通孔３が設けられている。
図２、４に示す如く、前記試料管４は、接地底面４ａを有した断面円形の管状の試験管であって、接地底面４ａから上方に向かって大径となるテーパ状に形成されている。試験管４は、上端が開口しており、この開口を塞ぐキャップ４ｄが試験管４の上端部に着脱自在に螺合している。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show a sample tube support 1 according to a first embodiment of the present invention.
The support 1 is a substantially rectangular plate member 2 that supports the sample tube 4 that is self-supporting on the ground bottom surface 4a. The plate member 2 is provided with a through hole 3 that supports the standing state of the sample tube 4. It has been.
As shown in FIGS. 2 and 4, the sample tube 4 is a tubular test tube having a circular cross section with a ground bottom surface 4a, and is formed in a tapered shape having a large diameter upward from the ground bottom surface 4a. . The upper end of the test tube 4 is open, and a cap 4d that closes the opening is detachably screwed to the upper end of the test tube 4.
図２の一部断面図に示すように、試験管４は、内底面４ｃを上面とする丸底部分４ｅを有し、この丸底部分４ｅから下方に起立壁４ｆが延出して上げ底状に形成されている。この起立壁４ｆの下端面４ａは、断面円環状の一様な面に形成されていて、上述した接地底面４ａを構成している。
試験管４は、接地底面４ａの直径（底径）Ｌが約１６．３ｍｍで、接地底面４ａから高さ約８８ｍｍの位置の直径が約１８ｍｍである。つまり、試験管４の外周面は、上方にいくほど大径となるテーパ面であり、外周面のテーパ角βは、tanβ＝1.7/88を解いて、βは約１．１度となる。
As shown in the partial sectional view of FIG. 2, the test tube 4 has a round bottom portion 4e having an inner bottom surface 4c as an upper surface, and a standing wall 4f extends downward from the round bottom portion 4e to form a raised bottom. Is formed. The lower end surface 4a of the standing wall 4f is formed in a uniform surface having an annular cross section, and constitutes the above-described ground contact bottom surface 4a.
The test tube 4 has a diameter (bottom diameter) L of the ground contact bottom surface 4a of about 16.3 mm, and a diameter at a height of about 88 mm from the ground contact bottom surface 4a is about 18 mm. That is, the outer peripheral surface of the test tube 4 is a tapered surface having a larger diameter as it goes upward, and the taper angle β of the outer peripheral surface solves tan β = 1.7 / 88, and β is about 1.1 degrees.
試験管４のテーパ面部分の上縁（底面４ａから高さ約８８ｍｍの位置）には、外方へ張り出すフランジを有しており、このフランジより上方の外周面に上述の螺合部分が形成さ
れている。
なお、試験管４の底径Ｌや、高さ、テーパ角β等は、上述した値に限らず、自立可能な接地底面４ａを有しているならば、テーパ状の試験管４でも、テーパのない試験管４の中途部にリブ（後述する留め部４ｂ）を設けたものでもよく、キャップ４ｄも螺合式でなく、ゴム栓、アルミキャップなどであってもよい。
At the upper edge of the tapered surface portion of the test tube 4 (position of about 88 mm in height from the bottom surface 4a), a flange projecting outward is provided, and the above-described screwed portion is formed on the outer peripheral surface above the flange. Is formed.
Note that the bottom diameter L, height, taper angle β, etc. of the test tube 4 are not limited to the above-described values, and the tapered test tube 4 can be tapered as long as it has a self-standing grounding bottom surface 4a. A rib (a fastening portion 4b to be described later) may be provided in the middle of the test tube 4 without the cap, and the cap 4d may be a rubber plug, an aluminum cap, or the like instead of being screwed.
また、試験管４は、内容量を表す目盛りが１ｃｃ刻みで記されている（図４参照）が、必須ではない。
図２、３に示すように、前記板部材２は、平面視で長方形で発泡スチロール製の板であって、縦約２００ｍｍ、横約１１０ｍｍ、板厚Ｗ１０ｍｍに形成されている。
板部材２には、上述の貫通孔３が複数（本実施形態では縦５×横３＝１５個）穿設され、貫通孔３の直径（孔径）Ｓは、約１７．５ｍｍであって、上述の試験管４の高さ方向の中途部（接地底面４ａから約６０ｍｍ）と同径に形成されている。
Further, the test tube 4 has a scale indicating the internal capacity in 1 cc increments (see FIG. 4), but is not essential.
As shown in FIGS. 2 and 3, the plate member 2 is a plate made of styrene foam having a rectangular shape in plan view, and is formed to have a length of about 200 mm, a width of about 110 mm, and a plate thickness W of 10 mm.
The plate member 2 has a plurality of the above-described through holes 3 (vertical 5 × 3 = 15 in this embodiment), and the diameter (hole diameter) S of the through hole 3 is about 17.5 mm. The test tube 4 is formed to have the same diameter as the middle portion in the height direction (about 60 mm from the ground contact bottom surface 4a).
貫通孔３の穿設方向は板部材２の厚み方向に沿っていて、厚み方向の切削や型抜きだけで、板部材２の表面２ａ側に露出した孔径Ｓ１と、裏面２ｂ側に露出した孔径Ｓ２とが同径となるように形成可能であるため、製造が容易となる。また、各貫通孔３は、所定間隔（中心間の距離が約３０ｍｍ）ごとに設けられており、縦横に隣接する貫通孔３間の距離は約１２．５ｍｍである。 The through-hole 3 is formed in the direction of the thickness of the plate member 2, and the hole diameter S1 exposed on the surface 2a side of the plate member 2 and the hole diameter exposed on the back surface 2b side only by cutting or die cutting in the thickness direction. Since it can form so that S2 may become the same diameter, manufacture becomes easy. Moreover, each through-hole 3 is provided for every predetermined space | interval (distance between centers is about 30 mm), and the distance between the through-holes 3 adjacent to the length and width is about 12.5 mm.
なお、板部材２の一端部（一端縁から約６０ｍｍの部分）は、貫通孔３が形成されておらず、この部分を把持部としたり、板部材２の表面２ａに記入スペース１１を設けてもよい。また、板部材２の形状、貫通孔３の孔径Ｓや間隔は、上述した値に限定されず、支持する試験管４に応じて、適宜変更可能である。
特に、板部材２の板厚Ｗは、試験管４の底径Ｌや重心Ｇの位置によって、約１０ｍｍに限らない（以下、図１及び使用態様参照）。
Note that one end of the plate member 2 (a portion about 60 mm from one end edge) is not formed with the through-hole 3, and this portion is used as a gripping portion or an entry space 11 is provided on the surface 2a of the plate member 2. Also good. Moreover, the shape of the plate member 2, the hole diameter S of the through-hole 3, and the space | interval are not limited to the value mentioned above, It can change suitably according to the test tube 4 to support.
In particular, the plate thickness W of the plate member 2 is not limited to about 10 mm depending on the position of the bottom diameter L and the center of gravity G of the test tube 4 (see FIG. 1 and the usage mode below).
図１〜５に示した支持具１の使用態様を説明する。
図１（ａ）に示す如く、地面に置いた板部材２の貫通孔３内で試験管４を自立させる（底面４ａで接地した姿勢であり、以下、底面接地姿勢Ｔとする）と、孔径Ｓ＞底径Ｌであるため、試験管４の底部と貫通孔３の内周壁との間で、隙間ｄ（約０．６ｍｍ）が確保できる。
The usage mode of the support 1 shown in FIGS.
As shown in FIG. 1 (a), when the test tube 4 is self-supported in the through-hole 3 of the plate member 2 placed on the ground (which is a posture grounded on the bottom surface 4a, hereinafter referred to as a bottom surface grounding posture T), the hole diameter Since S> bottom diameter L, a gap d (about 0.6 mm) can be secured between the bottom of the test tube 4 and the inner peripheral wall of the through hole 3.
この隙間ｄがあるため、起立した試験管４を抜き取る際には、片手で上方へ引き抜くだけでよく、抜取り作業が非常にスムースとなる。
図２中の仮想線で示すように、貫通孔３内の試験管４に対し、手の接触や揺れなど横方向の力が加わると、試験管４は、底面接地姿勢Ｔから底面４ａ縁を支点Ｏとして傾いていく。この傾きにつれて、底面接地姿勢Ｔ時には接地底面４ａの中心の略鉛直上方にある重心Ｇも、試験管４が傾く側へ移動していく。
Since there is this gap d, when the test tube 4 standing up is pulled out, it is only necessary to pull it up with one hand, and the pulling out operation becomes very smooth.
As shown by phantom lines in FIG. 2, when a lateral force such as hand contact or shaking is applied to the test tube 4 in the through hole 3, the test tube 4 moves from the bottom surface contact posture T to the bottom surface 4 a edge. It tilts as fulcrum O. In accordance with this inclination, the center of gravity G located substantially vertically above the center of the ground contact bottom surface 4a also moves to the side on which the test tube 4 tilts during the bottom surface contact posture T.
しかし、試験管４が傾けば、支点Ｏとなった底面４ａ縁とは反対側の底面４ａ縁が持ち上がることとなり、その反対側の底面４ａ縁は貫通孔３の内周壁に当接して（ここを当接点Ａとする）引っかかる（図１（ｂ）参照）。
よって、板部材２の板厚Ｗを、貫通孔３内で試験管４が傾いた場合に持ち上がる底面４ａ縁が貫通孔３の内周壁に当接可能に形成すれば、板部材２は、貫通孔３内で試験管４が傾いても起立状態を支持できる。
However, if the test tube 4 is tilted, the bottom surface 4a edge opposite to the bottom surface 4a edge serving as the fulcrum O is lifted, and the bottom surface 4a edge opposite to the bottom surface 4a is in contact with the inner peripheral wall of the through hole 3 (here (Refer to FIG. 1B).
Therefore, if the thickness W of the plate member 2 is formed so that the edge of the bottom surface 4a that lifts when the test tube 4 is tilted in the through hole 3 can be brought into contact with the inner peripheral wall of the through hole 3, the plate member 2 is penetrated. Even when the test tube 4 is inclined in the hole 3, the standing state can be supported.
なお、傾いて起立した姿勢（傾斜起立姿勢Ｋ）をとった試験管４は、支点Ｏと、当接点Ａと、支持点Ｂ（試験管４の外周面と貫通孔３の内周上縁との接触点）の３点で支持されている。
一方、板厚Ｗが薄すぎても、底面４ａ縁は貫通孔３へ引っかかることができないため、板部材２は、所定の板厚Ｗが必要である。
It should be noted that the test tube 4 taking an inclined and standing posture (tilted standing posture K) has a fulcrum O, a contact point A, and a support point B (the outer peripheral surface of the test tube 4 and the inner peripheral upper edge of the through hole 3). Are supported at three points.
On the other hand, even if the plate thickness W is too thin, the edge of the bottom surface 4a cannot be caught in the through-hole 3, so that the plate member 2 needs a predetermined plate thickness W.
すなわち、試験管４が貫通孔３内で任意の角度θで傾いたとしても、支点Ｏ反対側の試験管４の底面４ａ縁が、板部材２の上面と同じ高さ又は低い位置にくれば、底面４ａ縁の貫通孔３への引っかかりは確保されることとなる。
なお図１（ｃ）は、試験管４の底部角を側面視で直角に近似し、且つ貫通孔３の内周壁を側面視で鉛直面に近似した場合において、底径Ｌの試験管４が、孔径Ｓの貫通孔３の中
で最も傾いた（つまり、支点Ｏ反対側の試験管４の底面４ａ縁が最も持ち上がった）状態を示しており、このときの板厚Ｗは、Ｌ√(Ｓ2−Ｌ2)/Ｓの値と等しくなる（三角形の相似関係より）。
That is, even if the test tube 4 is inclined at an arbitrary angle θ in the through hole 3, if the edge of the bottom surface 4 a of the test tube 4 on the side opposite to the fulcrum O is at the same height or lower position as the upper surface of the plate member 2. The catch of the edge of the bottom surface 4a to the through hole 3 is ensured.
FIG. 1C shows that the bottom tube L of the test tube 4 is approximated to a right angle in a side view and the inner peripheral wall of the through hole 3 is approximated to a vertical surface in a side view. In the through hole 3 having the hole diameter S, the most inclined state (that is, the edge of the bottom surface 4a of the test tube 4 on the side opposite to the fulcrum O is raised most), the thickness W at this time is L√ ( It becomes equal to the value of S 2 −L 2 ) / S (from the similarity of triangles).
よってこの場合には、板部材２の板厚Ｗを、Ｌ√(Ｓ2−Ｌ2)/Ｓよりも厚く形成すれば、底面４ａ縁の貫通孔３への引っかかりが確保され、貫通孔３内で試験管４は、底面接地姿勢Ｔから傾斜起立姿勢Ｋへ姿勢変更可能となる。
図２中の矢印Ｘで示す如く、隣接する試験管４同士が同じ向きに傾けば、傾斜起立姿勢Ｋでの傾きは略等しいため、互いに接触することはない。
Therefore, in this case, if the plate thickness W of the plate member 2 is formed to be thicker than L√ (S 2 −L 2 ) / S, the bottom surface 4 a edge is secured to the through hole 3, and the through hole 3 The posture of the test tube 4 can be changed from the bottom surface contact posture T to the inclined standing posture K.
If the adjacent test tubes 4 are tilted in the same direction as indicated by an arrow X in FIG. 2, the tilts in the tilted standing posture K are substantially equal, and thus do not contact each other.
また、図２中の矢印Ｙのように、試験管４の断面形状、貫通孔３はそれぞれ円形であるため、試験管４は傾斜起立姿勢Ｋを維持したまま貫通孔３の周縁上を転がって、側面視で鉛直軸Ｊ回りに首振り状に回転可能となっている（図３中矢印Ｙも参照）。
したがって、試験管４に対し貫通孔３の周方向に沿って力がかかっても、この力を試験管４が首振り回転して逃がすことができる。
Also, as shown by the arrow Y in FIG. 2, the cross-sectional shape of the test tube 4 and the through hole 3 are each circular, so that the test tube 4 rolls on the periphery of the through hole 3 while maintaining the inclined standing posture K. In a side view, it can be swung around the vertical axis J (see also arrow Y in FIG. 3).
Therefore, even if a force is applied to the test tube 4 along the circumferential direction of the through-hole 3, the test tube 4 can be swung to escape the force.
また、図３中の矢印Ｚで示すように、ある試験管４が傾いて隣接する試験管４に当たっても、当てられた試験管４自体も鉛直軸Ｊ回りの首振り回転ができるため、各試験管４は、互いに当たった衝撃を逃がすように動けて、各試験管４の起立状態は、底面接地姿勢Ｔ及び傾斜起立姿勢Ｋのいずれかで確実に保たれる。
なお、各貫通孔３同士は、中心間の距離が約３０ｍｍとなる間隔で設けられていたが、試験管４の抜取り等に支障がない範囲で、さらに間隔を狭めて貫通孔３を板部材２に設けることも可能である。
Further, as shown by an arrow Z in FIG. 3, even when a certain test tube 4 tilts and hits an adjacent test tube 4, the applied test tube 4 itself can swing and rotate about the vertical axis J. The tubes 4 can move so as to release the impacts that hit each other, and the standing state of each test tube 4 is reliably maintained in either the bottom surface contact posture T or the inclined standing posture K.
The through-holes 3 are provided at intervals with a distance of about 30 mm between the centers. However, the through-holes 3 are made to be plate members by further reducing the intervals within a range that does not hinder the extraction of the test tube 4 or the like. 2 can also be provided.
貫通孔３内で試験管４を起立させた状態で、板部材２の前記一端部を把持して片手で持ち上げるだけで、試験管４は中途部（高さ方向の略中央部、又はその中央部より若干上側）までが貫通孔３に嵌る（このとき、前記隙間ｄはなくなる）こととなり、複数の試験管４を同時に簡単に持ち運ぶことができる。
なお、試験管４は、テーパ状の外周面が貫通孔３の内周部（厳密には、板部材２表面２ａ側の内周縁）に係止（当接）することで、高さ方向中途位置で留まっているといえ、この貫通孔３の内周部に係止した部分を、試験管４の留め部４ｂとする。
In a state where the test tube 4 is erected in the through-hole 3, the test tube 4 can be formed in the middle portion (approximately the center in the height direction or the center thereof) by simply holding the one end of the plate member 2 and lifting it with one hand. A portion slightly above the portion fits into the through-hole 3 (the gap d is eliminated at this time), and a plurality of test tubes 4 can be easily carried simultaneously.
The test tube 4 has a tapered outer peripheral surface that is engaged (contacted) with the inner peripheral portion of the through hole 3 (strictly, the inner peripheral edge on the surface 2a side of the plate member 2), so that the test tube 4 is halfway in the height direction. The portion locked to the inner peripheral portion of the through hole 3, which is said to remain at the position, is defined as a fastening portion 4 b of the test tube 4.
逆にいえば、このような留め部４ｂによって、貫通孔３に接地底面４ａ側から挿入された試料管４を係止するためには、貫通孔３の孔径Ｓは、接地底面４ａより大径で且つ留め部４ｂより小径でなくてはならない。なお、貫通孔３の孔径Ｓを接地底面４ａより大径となるように形成すれば、試験管４の底部と貫通孔３と間には隙間ｄができる。
図４に示す如く、複数の試験管４を所定温度で長時間保温する場合には、持ち運び状態の試験管の支持具１を、そのままウォーターバス５の容器５ａ内に入れれば、発泡スチロール製の板部材２が水面に浮くこととなり、簡単に保温作業に移れる。
Conversely, in order to lock the sample tube 4 inserted from the ground bottom surface 4a side into the through hole 3 by such a fastening portion 4b, the hole diameter S of the through hole 3 is larger than that of the ground bottom surface 4a. And it must be smaller in diameter than the fastening part 4b. In addition, if the hole diameter S of the through hole 3 is formed to be larger than the ground bottom surface 4 a, a gap d is formed between the bottom of the test tube 4 and the through hole 3.
As shown in FIG. 4, when a plurality of test tubes 4 are kept warm at a predetermined temperature for a long time, if the support 1 of the test tube in a portable state is placed in the container 5a of the water bath 5 as it is, a sheet made of polystyrene foam is used. The member 2 floats on the surface of the water, so that it is possible to easily move to the heat retaining work.
しかも、板部材２の貫通孔３に試験管４が中途部まで挿通していることから、試験管４のうち板部材２の表面２ａ（上面）から上の部分だけが、水面上から露出することとなり、試験管４上端と水面との距離を常に所定長さに保ち、水面等から試験管４内への雑菌混入を防止できる。
さらに、ウォーターバス５におけるサーモスタット５ｂの長時間使用によって、水Ｍが蒸発して容器５ａ内の水面が下がっても、図５に示す如く、容器５ａ内にあらかじめ十分な水量を入れておくことによって、水位が変化しても、水面上の露出距離は常に一定に保たれ、且つ水面下の試験管４底部と、容器５ａの内底面との距離が十分に確保されるため、随時水位を監視し、必要に応じて水Ｍを足す等の手間がかからず、保温作業の負担が非常に軽減される。
In addition, since the test tube 4 is inserted through the through hole 3 of the plate member 2 to the middle portion, only a portion of the test tube 4 above the surface 2a (upper surface) of the plate member 2 is exposed from the water surface. Thus, the distance between the upper end of the test tube 4 and the water surface is always kept at a predetermined length, and contamination with germs from the water surface or the like into the test tube 4 can be prevented.
Further, even if the water M evaporates and the water level in the container 5a falls due to long-time use of the thermostat 5b in the water bath 5, as shown in FIG. 5, a sufficient amount of water is put in the container 5a in advance. Even if the water level changes, the exposure distance on the water surface is always kept constant, and the distance between the bottom of the test tube 4 below the water surface and the inner bottom surface of the container 5a is sufficiently secured, so the water level is monitored at any time. However, it does not take time and effort to add water M as necessary, and the burden of heat insulation work is greatly reduced.
なお、ウォーターバス５の容器５ａの開口面に収まるように（つまり、ウォーターバス５内で水浴可能に）、板部材２の形状、大きさが構成されている。
図６は、本発明の第２実施形態に係る試料管の支持具１を示している。
第２実施形態と第１実施形態との相違点は、貫通孔３の孔径Ｓが板部材２の表面２ａ側に露出した孔径（表孔径）Ｓ１と、裏面２ｂ側に露出した孔径（裏孔径）Ｓ２とが異なるように形成されていることであり、以下に貫通孔３の変形例を２つ示す。
In addition, the shape and size of the plate member 2 are configured so as to fit in the opening surface of the container 5a of the water bath 5 (that is, capable of bathing in the water bath 5).
FIG. 6 shows a sample tube support 1 according to a second embodiment of the present invention.
The difference between the second embodiment and the first embodiment is that the hole diameter S of the through hole 3 is exposed on the front surface 2a side of the plate member 2 (front hole diameter) S1 and the hole diameter exposed on the back surface 2b side (back hole diameter). ) S2 is formed differently, and two modifications of the through hole 3 are shown below.
図６（ａ）には、貫通孔３の変形例１が示されている。この貫通孔３は、板部材２の表面２ａから裏面２ｂに向かって小径となるテーパ状（貫通孔３の内周面がテーパ面）に形成されており、表孔径Ｓ１は裏孔径Ｓ２より大径となっている。
このテーパ状貫通孔３に、これと同じテーパ角βを有した上述のような試験管４を挿入すると、互いのテーパ面同士が面接触するため、持ち運び時や保温作業中などには、試験管４が板部材２にしっかり保持される。
FIG. 6A shows a first modification of the through hole 3. The through hole 3 is formed in a tapered shape (the inner peripheral surface of the through hole 3 is a tapered surface) having a smaller diameter from the front surface 2a to the back surface 2b of the plate member 2, and the front hole diameter S1 is larger than the back hole diameter S2. It is a diameter.
When the above-described test tube 4 having the same taper angle β is inserted into the tapered through-hole 3, the taper surfaces come into surface contact with each other. The tube 4 is firmly held by the plate member 2.
この場合、留め部４ｂは、試験管４における貫通孔３と面接触する部分となる。
なお、テーパ状貫通孔３及び試験管４のテーパ角βが異なる場合には、試験管４のテーパ面において、板部材２の貫通孔３における表面２ａ側の内周縁、又は裏面２ｂ側の内周縁のいずれか係止（当接）した部分が、試験管４の留め部４ｂとなる。
また図６（ａ）中の仮想線に示す如く、接地させた板部材２の貫通孔３内の試験管４は、底面接地姿勢Ｔをとったときには、貫通孔３の内周壁との間に隙間ｄが形成され、変形例１のテーパ状貫通孔３であっても、片手で試験管４を抜き取れる。
In this case, the fastening portion 4 b is a portion that makes surface contact with the through hole 3 in the test tube 4.
When the taper-shaped through hole 3 and the test tube 4 have different taper angles β, the inner surface of the through-hole 3 of the plate member 2 on the front surface 2a side or the inner surface on the back surface 2b side of the test tube 4 is tapered. The portion of the peripheral edge that is locked (contacted) becomes the fastening portion 4 b of the test tube 4.
6A, when the test tube 4 in the through hole 3 of the grounded plate member 2 takes the bottom surface grounding posture T, it is between the inner peripheral wall of the through hole 3. Even if the gap d is formed and the tapered through hole 3 of the first modification is used, the test tube 4 can be pulled out with one hand.
図６（ｂ）にて示された変形例２の貫通孔３は、軸方向の中途部で裏面２ｂ側が小径となる段部３ａを備えており、この場合も同様に、表孔径Ｓ１＞裏孔径Ｓ２となる。
なお図６（ｂ）に示された試験管４は、テーパ面によって留め部４ｂを構成するのではなく、直管（ストレート管）の高さ方向中途部に、フランジ状の膨出部４ｇが外周面にわたって突出形成させている。この膨出部４ｇは、貫通孔３の孔径Ｓ（Ｓ１及びＳ２）より大径に形成されていた場合には、貫通孔３の内周部（厳密には、板部材２表面２ａ側の内周縁）に係止する。よって、この膨出部４ｇが留め部４ｂとなる。
The through-hole 3 of the modified example 2 shown in FIG. 6B is provided with a step portion 3a having a small diameter on the back surface 2b side in the middle in the axial direction. The hole diameter is S2.
The test tube 4 shown in FIG. 6 (b) does not constitute the fastening portion 4b by a tapered surface, but a flange-like bulging portion 4g is formed in the middle in the height direction of the straight pipe (straight pipe). It protrudes over the outer peripheral surface. When the bulging portion 4g is formed to have a diameter larger than the diameter S (S1 and S2) of the through hole 3, the inner peripheral portion of the through hole 3 (strictly speaking, the inner side of the plate member 2 surface 2a side) To the periphery). Therefore, this bulging part 4g becomes the fastening part 4b.
この膨出部４ｇが、上述した段部３ａ付き貫通孔３（変形例２）内に挿入可能な直径に形成された際には、側面視において試験管４は貫通孔３の内周部（内周壁の孔軸方向の中途部）と上下２段で接触する（接触点Ｐをもつ）こととなる（図６（ｂ）中の仮想線参照）。このように上下に接触点Ｐをもつことで、接触点Ｐが１段の場合よりも斜めに倒れにくく、持ち運び時等に試験管４がより安定する。 When the bulging portion 4g is formed to have a diameter that can be inserted into the above-described through hole 3 with the stepped portion 3a (Modification 2), the test tube 4 has an inner peripheral portion (see FIG. It is in contact with the upper and lower two stages (having a contact point P) in the middle of the hole axial direction of the inner peripheral wall (see the phantom line in FIG. 6B). By having the contact points P above and below in this way, the contact point P is less likely to fall obliquely than when the contact point P is one stage, and the test tube 4 is more stable when carried.
図６（ｃ）に示す如く、試験管４は、高さ方向の中途部から上部に向けて大径となる段部４ｈを備えていてもよく、大径部分が表孔径Ｓ１より大径の場合、段部４ｈは、板部材２の表面２ａ（貫通孔３の内周上縁周辺）に係止（面接触）する。よって、この段部４ｈが、貫通孔３の内周部に係止する留め部４ｂといえる。なお、図６（ｃ）では、変形例１であるテーパ状貫通孔３を用いている。 As shown in FIG. 6C, the test tube 4 may be provided with a stepped portion 4h having a large diameter from the midway portion in the height direction toward the upper portion, and the large diameter portion is larger in diameter than the surface hole diameter S1. In this case, the stepped portion 4h is engaged (surface contact) with the surface 2a of the plate member 2 (around the inner peripheral upper edge of the through hole 3). Therefore, it can be said that the stepped portion 4 h is a fastening portion 4 b that is locked to the inner peripheral portion of the through hole 3. In addition, in FIG.6 (c), the taper-shaped through-hole 3 which is the modification 1 is used.
さらには、テーパ状試験管４を、表孔径Ｓ１＞裏孔径Ｓ２である貫通孔３へ板部材２の裏面２ｂ側から挿入した場合には、表面２ａ側から挿入した場合よりも挿入深さが浅くなる。
また、図６（ｂ）中の仮想線で示すように、表面２ａ側から挿入した試験管４の留め部４ｂが貫通孔３内周の中途部で係止する場合には、裏面２ｂ側から挿入すると、貫通孔３の内周下縁で係止するため、挿入深さに違いがでる。
Furthermore, when the tapered test tube 4 is inserted from the back surface 2b side of the plate member 2 into the through-hole 3 where the front hole diameter S1> the back hole diameter S2, the insertion depth is greater than when inserted from the front surface 2a side. It becomes shallower.
6B, when the fastening portion 4b of the test tube 4 inserted from the front surface 2a side is locked in the middle portion of the through hole 3, the rear surface 2b side. When it is inserted, it is locked at the inner peripheral lower edge of the through hole 3, so that the insertion depth is different.
この挿入深さの違いを利用すれば、ウォーターバス５内の水浴時に水面上に露出する所定長さ等を選択可能となる。なお、板部材２の表裏は、記入スペース１１の有無で判断できる。なお、貫通孔３の孔径Ｓは、表孔径Ｓ１＜裏孔径Ｓ２であってもよい。
その他の構成は第１実施形態と同様である。
また、その他の実施形態として、板部材２の板厚Ｗを、試験管４の内底面４ｃを、例えば斜め約４５度上方（図２中の矢印Ｅ参照）から視認可能となるように形成してもよい。
By utilizing this difference in insertion depth, it is possible to select a predetermined length or the like that is exposed on the water surface when bathing in the water bath 5. In addition, the front and back of the plate member 2 can be determined by the presence or absence of the entry space 11. In addition, the hole diameter S of the through-hole 3 may be front hole diameter S1 <back hole diameter S2.
Other configurations are the same as those of the first embodiment.
As another embodiment, the thickness W of the plate member 2 is formed so that the inner bottom surface 4c of the test tube 4 is visible from, for example, about 45 degrees obliquely upward (see arrow E in FIG. 2). May be.
つまり、支持具１で起立した状態の試験管４内の検体を確認する場合、試験管４上部のキャップ４ｄをかわすために、試験管４の内底を斜め上方からのぞき込む必要がある。
斜め上方から内底面４ｃを視認可能な板厚Ｗの板部材２であれば、試験管４が貫通孔３内で起立状態であっても、試験管４の底部（もしくは下半分）が隠れることはなく、斜め上方から試験管４の内底面４ｃをのぞき込んで、検体の分量、有無や色チェック等の状態確認ができる。
That is, when confirming the specimen in the test tube 4 standing on the support 1, it is necessary to look into the inner bottom of the test tube 4 obliquely from above in order to dodge the cap 4d on the top of the test tube 4.
If the plate member 2 has a thickness W that allows the inner bottom surface 4 c to be viewed from obliquely above, the bottom (or lower half) of the test tube 4 is hidden even when the test tube 4 is standing in the through hole 3. No, it is possible to check the state of the sample, such as the amount, presence, color check, etc. by looking into the inner bottom surface 4c of the test tube 4 from diagonally above.
なお、視認角度は約４５度で十分といえるが、４５度より小さい角度で視認する場合は、視認角度４５度における板厚Ｗより、さらに薄くすればよい。
その他の構成は第１実施形態と同様である。
なお、本発明は前記実施形態における各部材の形状は、図１〜６に示すように構成することが最良である。しかし、前記実施形態に限定されるものではなく、部材、構成を種々変形したり、組み合わせを変更したりすることもできる。
In addition, although it can be said that the viewing angle is about 45 degrees, when viewing at an angle smaller than 45 degrees, it may be made thinner than the plate thickness W at the viewing angle of 45 degrees.
Other configurations are the same as those of the first embodiment.
In the present invention, the shape of each member in the embodiment is best configured as shown in FIGS. However, it is not limited to the said embodiment, A member, a structure can be variously deformed, and a combination can also be changed.
試料管４は、液状の検体を入れる試験管に限らず、バイアルや、チューブ等であってもよい。
板部材２は、発泡スチロール製でなくとも、発泡状又は多孔質状に成形されたポリウレタン、ポリオレフィン等の合成樹脂（プラスチック）等であればよく、さらには、木製など、水（保温作業で水浴時に用いる液体を含む）に浮く素材であればよい。
The sample tube 4 is not limited to a test tube into which a liquid specimen is placed, and may be a vial, a tube, or the like.
The plate member 2 is not necessarily made of polystyrene foam, but may be a synthetic resin (plastic) such as polyurethane or polyolefin molded into a foamed or porous shape. Any material can be used as long as it floats on the liquid (including the liquid used).
