Description

本発明は、複数の容器本体が一列に連なって設けられた密閉式の連結容器（いわゆる多連ＰＣＲチューブ）の各キャップを一度に開放するキャップ開放装置に関し、特に滅菌器に用いて好適である。また、本発明は、このキャップ開放装置に用いられる連設容器に関する。 The present invention relates to a cap opening device for opening each cap of a closed type connecting container (so-called multiple PCR tube) in which a plurality of container bodies are provided in a row, and is particularly suitable for use in a sterilizer. .. The present invention also relates to a continuous container used in this cap opening device.

多連ＰＣＲチューブは、複数個（例えば８個や１２個）の同一形状のキャップ付き容器本体が一列に連なって設けられたチューブであり、生化学分野の実験や研究において用いられる。ＰＣＲチューブは、容器本体内のサンプルの蒸発やサンプルへの異物混入等を防ぐためにキャップによって密閉されるが、一つ一つのキャップを手で開け閉めしたのでは作業効率が悪い。そこで、全てのキャップを一度に着脱できる装置（着脱具）が提案されている。例えば特許文献１には、ＰＣＲチューブをセットする基体と、基体に対してスライドさせることで基体に保持されたＰＣＲチューブのキャップを一度に開放させる蓋体とから構成された着脱具が開示されている。 The multiple PCR tube is a tube in which a plurality of (for example, 8 or 12) capped container bodies having the same shape are provided in a row, and is used in experiments and research in the field of biochemistry. The PCR tube is sealed with a cap to prevent evaporation of the sample in the container body and contamination of the sample with foreign matter, but if each cap is opened and closed by hand, the work efficiency is poor. Therefore, a device (detachment tool) that allows all caps to be attached and detached at once has been proposed. For example, Patent Document 1 discloses a detachable tool composed of a substrate on which a PCR tube is set and a lid that opens the cap of the PCR tube held on the substrate at once by sliding it with respect to the substrate. There is.

しかしながら、上記の特許文献１の着脱具は小型化しにくいという課題があり、狭い作業スペースで用いることが困難である。また、この着脱具を用いる場合には、基体を置くための机や作業台が必要となり、この点からも作業環境が制限される。なお、これらの課題はＰＣＲチューブのキャップを開放する場合に限って生じる課題ではなく、一列に連設された容器本体と、各容器本体に連結されたキャップとを有する連設容器の全てのキャップを一度に開放する場合に共通の課題である。 However, the above-mentioned attachment / detachment tool of Patent Document 1 has a problem that it is difficult to miniaturize it, and it is difficult to use it in a narrow work space. Further, when this attachment / detachment tool is used, a desk or a work table on which the substrate is placed is required, which also limits the work environment. It should be noted that these problems are not problems that occur only when the caps of the PCR tubes are opened, and all the caps of the continuous container having the container bodies connected in a row and the caps connected to each container body. This is a common issue when opening all at once.

［１．構成］
図１（ａ）〜（ｄ）は、本実施形態に係るキャップ開放装置に用いられる連設容器１を示す模式図である。本実施形態のキャップ開放装置は、図１（ａ）及び（ｂ）に示すような、一列に連設された容器本体２と、各容器本体２と連結されたキャップ４とを有する連設容器１の全てのキャップ４を一度に開放する装置である。本実施形態では、連設容器１として、同一形状の８つのチューブ（容器本体２及びキャップ４）が一連に設けられた市販の８連キャップ付きＰＣＲチューブを例示する。以下、ＰＣＲチューブに符号１を示す。 [1. composition]
1 (a) to 1 (d) are schematic views showing a continuous container 1 used in the cap opening device according to the present embodiment. The cap opening device of the present embodiment is a continuous container having a container main body 2 connected in a row and a cap 4 connected to each container main body 2 as shown in FIGS. 1A and 1B. It is a device that opens all the caps 4 of 1 at once. In the present embodiment, as the continuous container 1, a commercially available PCR tube with an 8-unit cap provided with eight tubes (container body 2 and cap 4) having the same shape in a series is exemplified. Hereinafter, reference numeral 1 is shown on the PCR tube.

図１（ａ）〜（ｄ）に示すように、本実施形態の容器本体２は円形の開口２ａを有し、径方向の寸法よりも深さ方向の寸法が長い細長形状に形成され、先端（容器の底）に向かって縮径されている。各容器本体２は、開口２ａの周囲の縁部（以下「開口縁部２ｅ」という）が他の部位よりも高強度に（例えば肉厚に）形成されている。８つの容器本体２は径方向に一列に並んで設けられ、隣接する容器本体２の開口縁部２ｅ同士が接続部２ｃによって連結されている。なお、以下の説明では、容器本体２が一列に並んだ方向を「列設方向Ｌ１」と呼ぶ。 As shown in FIGS. 1A to 1D, the container body 2 of the present embodiment has a circular opening 2a, is formed in an elongated shape having a depth dimension longer than a radial dimension, and a tip. The diameter is reduced toward (the bottom of the container). In each container body 2, the peripheral edge portion (hereinafter referred to as “opening edge portion 2e”) around the opening 2a is formed to have higher strength (for example, thicker) than other portions. The eight container main bodies 2 are provided side by side in a radial direction, and the opening edge portions 2e of the adjacent container main bodies 2 are connected to each other by the connecting portion 2c. In the following description, the direction in which the container bodies 2 are arranged in a row is referred to as "rowing direction L1".

８つのキャップ４のそれぞれは、各容器本体２と一体に設けられる。具体的には、容器本体２の開口縁部２ｅとキャップ４とが帯状の連結部６によって連結されている。連結部６は、開口縁部２ｅから、列設方向Ｌ１に対して４５度方向に延設されるとともに折り返されており、キャップ４の密閉状態では屈曲された状態となる。なお、連結部６の折り返し線６ｅは連結部６の延設方向に直交する。 Each of the eight caps 4 is provided integrally with each container body 2. Specifically, the opening edge portion 2e of the container body 2 and the cap 4 are connected by a strip-shaped connecting portion 6. The connecting portion 6 extends from the opening edge portion 2e in the direction of 45 degrees with respect to the row arrangement direction L1 and is folded back, and is in a bent state when the cap 4 is sealed. The folding line 6e of the connecting portion 6 is orthogonal to the extending direction of the connecting portion 6.

キャップ４は、開口２ａを閉鎖する平面状の蓋部４ａと、開口２ａの内側に入り込んで密閉する筒部４ｂとを有する。蓋部４ａは、開口縁部２ｅよりも径方向外側に広がったフランジ部４ｆを有する。本実施形態のフランジ部４ｆは、開口縁部２ｅよりも径方向外側に突出した先細形状に形成され、容器本体２の径方向中心を挟んで連結部６の反対側に配置される。なお、本実施形態のキャップ４の蓋部４ａは、図１（ｂ）に示すように、連結部６とフランジ部４ｆとを繋ぐ仮想線Ｂに対して左右対称形状に形成されている。ＰＣＲチューブ１は、連結部６が支点となり、後述する押圧部２３が力点となって、作用点であるフランジ部４ｆを押すことでキャップ４が開放される。 The cap 4 has a flat lid portion 4a that closes the opening 2a, and a tubular portion 4b that enters and seals inside the opening 2a. The lid portion 4a has a flange portion 4f that extends radially outward from the opening edge portion 2e. The flange portion 4f of the present embodiment is formed in a tapered shape protruding radially outward from the opening edge portion 2e, and is arranged on the opposite side of the connecting portion 6 with the radial center of the container body 2 interposed therebetween. As shown in FIG. 1B, the lid portion 4a of the cap 4 of the present embodiment is formed in a symmetrical shape with respect to the virtual line B connecting the connecting portion 6 and the flange portion 4f. In the PCR tube 1, the connecting portion 6 serves as a fulcrum, the pressing portion 23 described later serves as a force point, and the cap 4 is opened by pushing the flange portion 4f, which is the point of action.

キャップ開放装置は、図４（ａ）及び（ｂ）に示すように、容器本体２の列設方向Ｌ１に直交する方向から８つの容器本体２を挟んで組み合わされる第一部品１０及び第二部品２０を備える。以下、これら二つの部品１０，２０を組み合わせる方向（すなわち、列設方向Ｌ１に直交する方向）を「合わせ方向Ｌ２」と呼ぶ。図２及び図３に示すように、二つの部品１０，２０はいずれも略直方体形状の外形を有し、長手方向が列設方向Ｌ１に相当し、高さ方向が合わせ方向Ｌ２に相当する。なお、列設方向Ｌ１及び合わせ方向Ｌ２のいずれにも直交する方向（直方体形状の短手方向）は、後述する突出方向Ｌ３に相当する。第一部品１０と第二部品２０とは、列設方向Ｌ１及び突出方向Ｌ３のそれぞれに延びる四辺で囲まれた面同士を対向させて組み合わされる。以下、これらの面をそれぞれ第一対向面１１，第二対向面２１と呼ぶ。 As shown in FIGS. 4A and 4B, the cap opening device includes the first component 10 and the second component that are combined with the eight container bodies 2 sandwiched from the direction orthogonal to the rowing direction L1 of the container body 2. 20 is provided. Hereinafter, the direction in which these two parts 10 and 20 are combined (that is, the direction orthogonal to the rowing direction L1) is referred to as "alignment direction L2". As shown in FIGS. 2 and 3, both of the two parts 10 and 20 have a substantially rectangular parallelepiped outer shape, the longitudinal direction corresponds to the rowing direction L1, and the height direction corresponds to the alignment direction L2. The direction orthogonal to both the rowing direction L1 and the alignment direction L2 (the lateral direction of the rectangular parallelepiped shape) corresponds to the protruding direction L3 described later. The first component 10 and the second component 20 are combined so that the surfaces surrounded by the four sides extending in the rowing direction L1 and the projecting direction L3 face each other. Hereinafter, these surfaces will be referred to as a first facing surface 11 and a second facing surface 21, respectively.

図２に示すように、第一部品１０は、第二部品２０と対向する第一対向面１１に凹設された所定数の第一凹部１２と、第一対向面１１における第一凹部１２の一側（図中左側）に凹設された溝部１３とを有する。第一凹部１２は、突出方向Ｌ３に延設された断面半円形状の窪みであり、本実施形態では容器本体２の個数と同じ数だけ設けられる。すなわち、本実施形態では、「所定数」が８である場合を例示する。 As shown in FIG. 2, the first component 10 includes a predetermined number of first recesses 12 recessed in the first facing surface 11 facing the second component 20, and a first recess 12 in the first facing surface 11. It has a groove portion 13 recessed on one side (left side in the drawing). The first recess 12 is a recess having a semicircular cross section extending in the protruding direction L3, and is provided in the same number as the number of the container main body 2 in the present embodiment. That is, in the present embodiment, the case where the "predetermined number" is 8 is illustrated.

第一凹部１２は、容器本体２の略半分（容器本体２の接続部２ｃよりも連結部６側の部分）を収容（嵌合）して、容器本体２の列設方向Ｌ１への動きを規制する機能を持つ。第一凹部１２の一側は開放されており、他側（図中右側）は閉鎖されている。この一側には、容器本体２の開口縁部２ｅが接触配置される。すなわち、ＰＣＲチューブ１の容器本体２は、一側にキャップ４が位置する姿勢で第一凹部１２に収容される。これにより、キャップ４は一側（図２中の左側）に向かって開放される。 The first recess 12 accommodates (fits) approximately half of the container body 2 (the portion of the container body 2 on the connecting portion 6 side of the connecting portion 2c), and moves the container body 2 in the rowing direction L1. It has a function to regulate. One side of the first recess 12 is open, and the other side (right side in the figure) is closed. The opening edge 2e of the container body 2 is contact-arranged on this one side. That is, the container body 2 of the PCR tube 1 is housed in the first recess 12 in a posture in which the cap 4 is located on one side. As a result, the cap 4 is opened toward one side (left side in FIG. 2).

本実施形態の溝部１３は、列設方向Ｌ１に一直線状に延設された断面コ字状の窪みであり、屈曲状態の連結部６が収容される。溝部１３は、列設方向Ｌ１に延設された対向する二つの壁部１３ａ，１３ｂを有する。図２，図４（ａ）及び（ｂ）に示すように、二つの壁部１３ａ，１３ｂのうち、キャップ４の開放側に位置する一方の壁部１３ａ（図２中左端の壁部、以下「第一壁部１３ａ」という）の高さは、第一凹部１２側に位置する他方の壁部１３ｂ（以下「第二壁部１３ｂ」という）の高さよりも低く形成される。第二壁部１３ｂには、第一凹部１２と連続する半円形状の窪みが形成されており、容器本体２が第一凹部１２に収容された状態で連結部６が接触配置される。 The groove portion 13 of the present embodiment is a recess having a U-shaped cross section extending in a straight line in the rowing direction L1, and accommodates the connecting portion 6 in a bent state. The groove portion 13 has two facing wall portions 13a and 13b extending in the rowing direction L1. As shown in FIGS. 2 and 4 (a) and 4 (b), of the two wall portions 13a and 13b, one wall portion 13a located on the open side of the cap 4 (the leftmost wall portion in FIG. 2, hereinafter The height of the "first wall portion 13a") is formed to be lower than the height of the other wall portion 13b (hereinafter referred to as the "second wall portion 13b") located on the first recess 12 side. A semicircular recess continuous with the first recess 12 is formed in the second wall portion 13b, and the connecting portion 6 is contact-arranged in a state where the container body 2 is housed in the first recess 12.

本実施形態第一壁部１３ａの高さは、容器本体２が第一凹部１２に収容された状態で連結部６と接する位置において他の位置よりも高く形成されている。以下、第一壁部１３ａのうち、その高さが他部よりも高く形成された部位（第一壁部１３ａのうち連結部６と接する部位）を山部１３ｃと呼ぶ。本実施形態の山部１３ｃ（突出部）は、図４（ｂ）に示すように、キャップ開放装置をキャップ４側から見たときに（以下「正面視で」という）、連結部６の略全体と重なるようになっている。具体的には、溝部１３に連結部６が収容された状態をキャップ４側から見たときに、山部１３ｃにおける連結部６と重なる辺１３ｅが、連結部６の折り返し線６ｅと平行になるように形成されている。本実施形態では、山部１３ｃが正面視で直角三角形状となっている。 The height of the first wall portion 13a of the present embodiment is formed higher than the other positions at the position where the container body 2 is in contact with the connecting portion 6 while being housed in the first recess 12. Hereinafter, the portion of the first wall portion 13a formed to be higher than the other portions (the portion of the first wall portion 13a in contact with the connecting portion 6) is referred to as a mountain portion 13c. As shown in FIG. 4B, the mountain portion 13c (protruding portion) of the present embodiment is an abbreviation for the connecting portion 6 when the cap opening device is viewed from the cap 4 side (hereinafter referred to as “front view”). It overlaps with the whole. Specifically, when the state in which the connecting portion 6 is housed in the groove portion 13 is viewed from the cap 4 side, the side 13e overlapping the connecting portion 6 in the mountain portion 13c becomes parallel to the folding line 6e of the connecting portion 6. It is formed like this. In the present embodiment, the mountain portion 13c has a right-angled triangular shape when viewed from the front.

本実施形態のキャップ開放装置は、第二壁部１３ｂよりも高さ寸法が小さい第一壁部１３ａが、部分的に高くなるように形成されている。このため、第一凹部１２に容器本体２が収容された状態では、正面視で、キャップ４の蓋部４ａと第一壁部１３ａとが重ならず、溝部１３に収容された連結部６と第一壁部１３ａ（山部１３ｃ）とが重なる。これにより、連結部６を支点としてキャップ４が開放されるときに、支点（連結部６）が確実に支持されるとともに蓋部４ａが開放されやすくなる。 The cap opening device of the present embodiment is formed so that the first wall portion 13a, which has a smaller height dimension than the second wall portion 13b, is partially raised. Therefore, in the state where the container body 2 is housed in the first recess 12, the lid portion 4a of the cap 4 and the first wall portion 13a do not overlap with each other in the front view, and the connecting portion 6 housed in the groove portion 13 It overlaps with the first wall portion 13a (mountain portion 13c). As a result, when the cap 4 is opened with the connecting portion 6 as a fulcrum, the fulcrum (connecting portion 6) is surely supported and the lid portion 4a is easily opened.

図３に示すように、第二部品２０は、第一部品１０と対向する第二対向面２１に凹設された所定数の第二凹部２２と、第二凹部２２の一側（図中左側）であって第二対向面２２の法線方向（すなわち合わせ方向Ｌ２）及び列設方向Ｌ１のいずれにも直交する方向に突設された所定数の押圧部２３とを有する。なお、押圧部２３が突設された方向を「突出方向Ｌ３」という。第二凹部２２及び押圧部２３の各個数は、第一凹部１２の個数と同一であり、本実施形態ではＰＣＲチューブ１の容器本体２の個数と同じ数（すなわち８つ）とされる。 As shown in FIG. 3, the second component 20 has a predetermined number of second recesses 22 recessed in the second facing surface 21 facing the first component 10 and one side of the second recess 22 (left side in the drawing). ), And has a predetermined number of pressing portions 23 projecting in a direction orthogonal to both the normal direction of the second facing surface 22 (that is, the alignment direction L2) and the rowing direction L1. The direction in which the pressing portion 23 is projected is referred to as "protruding direction L3". The number of each of the second recess 22 and the pressing portion 23 is the same as the number of the first recess 12, and in this embodiment, the number is the same as the number of the container body 2 of the PCR tube 1 (that is, eight).

第二凹部２２は、第一凹部１２と同様、突出方向Ｌ３に延設された断面半円形状の窪みであり、容器本体２の略半分（容器本体２の接続部２ｃよりもフランジ部４ｆ側の部分）を収容（嵌合）して容器本体２の列設方向Ｌ１への動きを規制する機能を持つ。第二凹部２２の一側は開放されており、他側（図中右側）は閉鎖されている。この一側に押圧部２３が設けられる。すなわち、第一部品１０と第二部品２０とが容器本体２を挟んで組み合わされた状態（以下「組合せ状態」という）で、溝部１３と押圧部２３とが突出方向Ｌ３において同一側（キャップ４側）に位置する。 Like the first recess 12, the second recess 22 is a recess having a semicircular cross section extending in the protruding direction L3, and is approximately half of the container body 2 (flange portion 4f side of the connecting portion 2c of the container body 2). It has a function of accommodating (fitting) the container body 2 and restricting the movement of the container body 2 in the rowing direction L1. One side of the second recess 22 is open, and the other side (right side in the figure) is closed. A pressing portion 23 is provided on this one side. That is, in a state where the first component 10 and the second component 20 are combined with the container body 2 sandwiched between them (hereinafter referred to as "combination state"), the groove portion 13 and the pressing portion 23 are on the same side (cap 4) in the protruding direction L3. Located on the side).

図３，図４（ａ）及び（ｂ）に示すように、押圧部２３は、キャップ４のフランジ部４ｆを押す力点となる部位である。本実施形態の押圧部２３は、正面視でホームベースのような形状に形成されており、その端面が平面状とされてフランジ部４ｆと面接触する。押圧部２３は、図４（ａ）及び（ｂ）に示すように、組合せ状態をキャップ４側から見たときに、フランジ部４ｆと重なる辺２３ｅが仮想線Ｂに対して直交するように形成されている。これにより、押圧部２３とフランジ部４ｆとの重なる面積が大きくなる。 As shown in FIGS. 3 and 4 (a) and 4 (b), the pressing portion 23 is a portion serving as a force point for pushing the flange portion 4f of the cap 4. The pressing portion 23 of the present embodiment is formed in a shape like a home base when viewed from the front, and its end surface is made flat so as to come into surface contact with the flange portion 4f. As shown in FIGS. 4A and 4B, the pressing portion 23 is formed so that the side 23e overlapping the flange portion 4f is orthogonal to the virtual line B when the combined state is viewed from the cap 4 side. Has been done. As a result, the area where the pressing portion 23 and the flange portion 4f overlap increases.

ＰＣＲチューブ１は、第一部品１０の溝部１３に全ての連結部６が収容されるとともに第一凹部１２に容器本体２の略半分が収容され、第二凹部２２に容器本体２の残り半分が収容されるように第二部品２０が組み合わされる。このとき、押圧部２３が、合わせ方向Ｌ２において容器本体２と重なるように（すなわち、押圧部２３がキャップ４から容器本体２側に離されて）、第二部品２０が組み合わされる。このように、第一部品１０と第二部品２０とで容器本体２を挟んだ状態（組合せ状態）で、第一部品１０と第二部品２０とが突出方向Ｌ３に相対的にスライドされると、押圧部２３はキャップ４のフランジ部４ｆを押圧する。 In the PCR tube 1, all the connecting portions 6 are housed in the groove 13 of the first component 10, about half of the container body 2 is housed in the first recess 12, and the other half of the container body 2 is housed in the second recess 22. The second component 20 is combined so that it is accommodated. At this time, the second component 20 is combined so that the pressing portion 23 overlaps the container main body 2 in the alignment direction L2 (that is, the pressing portion 23 is separated from the cap 4 toward the container main body 2). In this way, when the container body 2 is sandwiched between the first component 10 and the second component 20 (combination state), the first component 10 and the second component 20 are relatively slid in the protruding direction L3. , The pressing portion 23 presses the flange portion 4f of the cap 4.

図２及び図４（ａ）に示すように、本実施形態の第一部品１０は、最も外側に位置する二つの第一凹部１２の外側に、第一対向面１１よりも第二部品２０側に突出するように立設された一対のリブ１５を有する。すなわち、一対のリブ１５は、第一部品１０の列設方向Ｌ１の両側方のそれぞれに設けられ、左右対称形状（鏡面対称形状）に形成される。本実施形態の各リブ１５は、突出方向Ｌ３の寸法が列設方向Ｌ１の寸法（厚み）よりも大きい平板状である。各リブ１５は、正面視で、第一部品１０の列設方向Ｌ１の両側面１４の各下部から列設方向Ｌ１に延設されるとともに合わせ方向Ｌ２に屈曲形成されたＬ字状に形成される。各リブ１５の先端には、内側に向かって突出した爪部１６が設けられる。 As shown in FIGS. 2 and 4A, the first component 10 of the present embodiment is located outside the two outermost first recesses 12 and is closer to the second component 20 than the first facing surface 11. It has a pair of ribs 15 erected so as to project from. That is, the pair of ribs 15 are provided on both sides of the rowing direction L1 of the first component 10 and are formed in a symmetrical shape (mirror plane symmetrical shape). Each rib 15 of the present embodiment has a flat plate shape in which the dimension in the protruding direction L3 is larger than the dimension (thickness) in the rowing direction L1. Each rib 15 is formed in an L shape that extends from each lower portion of both side surfaces 14 of the rowing direction L1 of the first component 10 in the rowing direction L1 and is bent in the mating direction L2 when viewed from the front. NS. At the tip of each rib 15, a claw portion 16 projecting inward is provided.

また、第二部品２０は、第二対向面２１と直交するとともに突出方向Ｌ３に延在する二つの側面２４に形成された一対の段差部２６を有する。側面２４は、第二部品２０の列設方向Ｌ１の両側に位置する面であり、段差部２６は、側面２４の合わせ方向Ｌ２の中間部に設けられる。図４（ａ）及び（ｂ）に示すように、段差部２６は、第一部品１０及び第二部品２０の組合せ状態で爪部１６が引っ掛かる位置と形状とに形成される。爪部１６が段差部２６に引っ掛かることで、第一部品１０及び第二部品２０が相対的に突設方向Ｌ３以外には動かなくなるため、スライドしやすくなる。 Further, the second component 20 has a pair of stepped portions 26 formed on two side surfaces 24 which are orthogonal to the second facing surface 21 and extend in the projecting direction L3. The side surface 24 is a surface located on both sides of the second component 20 in the rowing direction L1, and the step portion 26 is provided in the middle portion of the side surface 24 in the alignment direction L2. As shown in FIGS. 4A and 4B, the step portion 26 is formed at a position and shape in which the claw portion 16 is hooked in the combined state of the first component 10 and the second component 20. When the claw portion 16 is caught on the stepped portion 26, the first component 10 and the second component 20 are relatively immobile except in the projecting direction L3, so that the sliding portion becomes easier to slide.

また、本実施形態の第一部品１０は、図２，図４（ａ）及び（ｂ）に示すように、第一対向面１１の他側（図中右側）の角部に突設された凸部１７（第一係合部）を有する。さらに、図３，図４（ａ）及び（ｂ）に示すように、第二部品２０には、この凸部１７と係合することでスライドをロックする切欠き部２７（第二係合部）が設けられる。切欠き部２７は、第二対向面２１の他側の縁部を切り欠いて形成される。なお、第一部品１０に切欠き部が設けられ、第二部品２０に凸部が設けられていてもよい。これら凸部１７及び切欠き部２７によりロック機構が形成される。 Further, as shown in FIGS. It has a convex portion 17 (first engaging portion). Further, as shown in FIGS. 3 and 4 (a) and 4 (b), the second component 20 has a notch 27 (second engaging portion) that locks the slide by engaging with the convex portion 17. ) Is provided. The notch 27 is formed by notching the other edge of the second facing surface 21. The first component 10 may be provided with a notch, and the second component 20 may be provided with a convex portion. A locking mechanism is formed by the convex portion 17 and the notch portion 27.

［２．作用，効果］
ここで、上述したキャップ開放装置によりＰＣＲチューブ１のキャップ４を開放する手順を説明する。まず、第一部品１０の溝部１３に屈曲状態の連結部６を収容しつつ、第一凹部１２に容器本体２の略半分を収容する。次に、第二凹部２２に容器本体２の残り半分が入るように、第二部品２０を第一部品１０に組み合わせる。このとき、図４（ｂ）及び図５（ａ）に示すように、押圧部２３がキャップ４のフランジ部４ｆに当接するように、第二部品２０を第一部品１０に対して突出方向Ｌ３にずらして組み合わせる。なお、この組合せ状態では、爪部１６が段差部２６に引っ掛かる。 [2. Action, effect]
Here, the procedure for opening the cap 4 of the PCR tube 1 by the cap opening device described above will be described. First, the groove 13 of the first component 10 accommodates the bent connecting portion 6, while the first recess 12 accommodates approximately half of the container body 2. Next, the second component 20 is combined with the first component 10 so that the other half of the container body 2 fits into the second recess 22. At this time, as shown in FIGS. 4B and 5A, the second component 20 is projected from the first component 10 in the protruding direction L3 so that the pressing portion 23 abuts on the flange portion 4f of the cap 4. Shift and combine. In this combined state, the claw portion 16 is caught by the step portion 26.

そして、爪部１６を段差部２６に沿わせて、図５（ａ）中に黒塗り矢印で示すように、第一部品１０と第二部品２０とを突出方向Ｌに相対的にスライドさせる。これにより、溝部１３内の連結部６が支点となり、押圧部２３（力点）がフランジ部４ｆ（作用点）を押圧するため、図５（ｂ）に示すように、全てのキャップ４が一斉に開放される。なお、凸部１７と切欠き部２７とが係合することで、第一部品１０と第二部品２０とのスライドがロックされるため、第一部品１０及び第二部品２０とＰＣＲチューブ１とは図５（ｂ）に示す状態で保持される。 Then, the claw portion 16 is slid along the step portion 26, and the first component 10 and the second component 20 are relatively slid in the protruding direction L as shown by the black-painted arrows in FIG. 5 (a). As a result, the connecting portion 6 in the groove portion 13 serves as a fulcrum, and the pressing portion 23 (force point) presses the flange portion 4f (action point). Therefore, as shown in FIG. 5 (b), all the caps 4 are simultaneously pressed. It will be released. By engaging the convex portion 17 and the notch portion 27, the slide between the first component 10 and the second component 20 is locked, so that the first component 10 and the second component 20 and the PCR tube 1 are used. Is held in the state shown in FIG. 5 (b).

したがって、上述したキャップ開放装置によれば、全てのキャップ４を一度に簡単に開けることができ、作業効率を高めることができる。また、コンパクトな構成であることから、手のひらや指の上で作業することができる。言い換えると、机や作業台等がない場所であってもＰＣＲチューブ１のキャップ４を開放できるため、作業環境を問わず使用することができる。このため、例えば使用済みのＰＣＲチューブ１を滅菌器で滅菌する場合に、滅菌器の釜（チャンバー）の内部に手を入れて、釜内でＰＣＲチューブ１のキャップ４を開放する作業を行うことができる。すなわち、上述したキャップ開放装置であれば、制限された空間での作業も可能となる。 Therefore, according to the cap opening device described above, all the caps 4 can be easily opened at one time, and the work efficiency can be improved. In addition, because of its compact structure, it is possible to work on the palm or fingers. In other words, since the cap 4 of the PCR tube 1 can be opened even in a place where there is no desk, work table, or the like, it can be used regardless of the work environment. Therefore, for example, when sterilizing a used PCR tube 1 with a sterilizer, the work of putting a hand inside the kettle (chamber) of the sterilizer and opening the cap 4 of the PCR tube 1 in the kettle is performed. Can be done. That is, with the cap opening device described above, it is possible to work in a limited space.

また、上述したキャップ開放装置によれば、連結部６が収容される一本の溝部１３が一直線状に設けられているため、第一部品１０の形状を簡素化できる。
さらに、溝部１３は、第一壁部１３ａの高さ寸法が第二壁部１３ｂの高さ寸法よりも小さく形成されているため、キャップ４の開放が第一壁部１３ａで妨げられない。一方で、第一壁部１３ａは、連結部６と接する位置では他の位置よりも高さ寸法が大きく形成されているため、キャップ４のフランジ部４ｆが押圧部２３で押されたときに、支点となる連結部６の動きを規制できる。これらによって、小さな力で簡単にキャップ４を開けることができる。 Further, according to the cap opening device described above, since one groove portion 13 in which the connecting portion 6 is housed is provided in a straight line, the shape of the first component 10 can be simplified.
Further, since the groove portion 13 is formed so that the height dimension of the first wall portion 13a is smaller than the height dimension of the second wall portion 13b, the opening of the cap 4 is not hindered by the first wall portion 13a. On the other hand, since the first wall portion 13a is formed to have a larger height dimension than the other positions at the position where it is in contact with the connecting portion 6, when the flange portion 4f of the cap 4 is pressed by the pressing portion 23, The movement of the connecting portion 6 serving as a fulcrum can be regulated. With these, the cap 4 can be easily opened with a small force.

特に、上述した第一壁部１３ａは、正面視で、山部１３ｃにおける連結部６と重なる辺１３ｅが連結部６の折り返し線６ｅと平行になるように形成されているため、連結部６と山部１３ｃとの重なる面積を大きくできる。これにより、フランジ部４ｆが押されたときに支点となる連結部６の動きをより規制できるため、キャップ４が開きやすくなる。
また、上述した押圧部２３は、正面視で、フランジ部４ｆと重なる辺２３ｅが仮想線Ｂと直交するように形成されているため、押圧部２３とフランジ部４ｆとの重なる面積を大きくでき、キャップが開きやすくなる。 In particular, the above-mentioned first wall portion 13a is formed so that the side 13e overlapping the connecting portion 6 in the mountain portion 13c is parallel to the folding line 6e of the connecting portion 6 in the front view. The area that overlaps with the mountain portion 13c can be increased. As a result, the movement of the connecting portion 6 serving as a fulcrum when the flange portion 4f is pushed can be further regulated, so that the cap 4 can be easily opened.
Further, since the above-mentioned pressing portion 23 is formed so that the side 23e overlapping the flange portion 4f is orthogonal to the virtual line B in the front view, the overlapping area between the pressing portion 23 and the flange portion 4f can be increased. The cap is easier to open.

上述したキャップ開放装置によれば、リブ１５の先端に設けられた爪部１６が、第二部品２０の側面２４に設けられた段差部２６に引っ掛けられるため、第一部品１０と第二部品２０とのスライドを案内することができる。これにより、キャップ４の開放作業がより簡単になる。
さらに、第一部品１０の凸部１７と第二部品２０の切欠き部２７とが係合することでスライドがロックされるため、キャップ４が所定角度だけ開いたところで第一部品１０と第二部品２０とがそれ以上スライドしなくなる。すなわち、キャップ４の開放度合いを凸部１７及び切欠き部２７で制限することができるため、容器本体２の内容物の漏出を抑制できる。また、凸部１７及び切欠き部２７により第一部品１０と第二部品２０とがロックされることで、キャップ４の開放状態を保つことができる。このため、例えばキャップ開放装置とともにＰＣＲチューブ１を滅菌にかける場合、キャップ４が滅菌途中で閉まることを防止できる。 According to the cap opening device described above, the claw portion 16 provided at the tip of the rib 15 is hooked on the stepped portion 26 provided on the side surface 24 of the second component 20, so that the first component 10 and the second component 20 are hooked. Can guide the slide with. This makes the opening work of the cap 4 easier.
Further, since the slide is locked by engaging the convex portion 17 of the first component 10 and the notched portion 27 of the second component 20, the first component 10 and the second component 10 and the second component 10 are opened when the cap 4 is opened by a predetermined angle. The part 20 does not slide any more. That is, since the degree of opening of the cap 4 can be limited by the convex portion 17 and the notch portion 27, leakage of the contents of the container body 2 can be suppressed. Further, the first component 10 and the second component 20 are locked by the convex portion 17 and the notch portion 27, so that the open state of the cap 4 can be maintained. Therefore, for example, when the PCR tube 1 is sterilized together with the cap opening device, it is possible to prevent the cap 4 from closing during sterilization.

また、上述したキャップ開放装置によれば、市販の８連キャップ付きＰＣＲチューブ１のキャップ４を簡単に開けることができる。なお、キャップ４のフランジ部４ｆが舌形状であるＰＣＲチューブ１であれば、より簡単に、より小さな力でキャップ４を開けることができる。
なお、上述したキャップ開放装置に用いられる連設容器１（例えばＰＣＲチューブ）であれば、作業環境を問わず、簡単に全てのキャップ４を開けることができる。 Further, according to the cap opening device described above, the cap 4 of the commercially available PCR tube 1 with an 8-unit cap can be easily opened. If the flange portion 4f of the cap 4 is a tongue-shaped PCR tube 1, the cap 4 can be opened more easily and with a smaller force.
If the continuous container 1 (for example, PCR tube) used in the cap opening device described above is used, all the caps 4 can be easily opened regardless of the working environment.

［３．その他］
上述したキャップ開放装置及び連設容器１の構成は一例であって、上述したものに限られない。例えば、上述した段差部２６の代わりに、爪部１６がスライドする溝が切ってあってもよい。また、リブ１５，爪部１６及び段差部２６を省略してもよい。上述したキャップ開放装置では、凸部１７及び切欠き部２７によりロック機構が形成されているが、これら以外の構成によってロック機構が形成されてもよい。ロック機構は少なくとも、二つの部品１０，２０のスライドを規制する（ロックする）構成であればよく、その位置や形状は特に限られない。 [3. others]
The configuration of the cap opening device and the continuous container 1 described above is an example, and is not limited to the above. For example, instead of the step portion 26 described above, a groove through which the claw portion 16 slides may be cut. Further, the rib 15, the claw portion 16, and the step portion 26 may be omitted. In the cap opening device described above, the lock mechanism is formed by the convex portion 17 and the notch portion 27, but the lock mechanism may be formed by a configuration other than these. The locking mechanism may have at least a configuration that regulates (locks) the slides of the two parts 10 and 20, and its position and shape are not particularly limited.

上述したキャップ開放装置では、キャップ４の連結部６が収容される溝部１３が一直線状に設けられる場合を例示したが、溝部の形状や個数はこれに限られない。例えば、溝部の個数を第一凹部１２の個数と同一とし、連結部６が位置する部分に凹設された所定数の溝部を並設してもよい。このような構成であっても、上述した実施形態と同様に、二つの部品１０，２０を相対的にスライドさせることでキャップ４を一度に開放できる。なお、溝部１３を構成する壁部１３ａ，１３ｂの高さ寸法やその形状は、連設容器に合わせて設定すればよい。 In the cap opening device described above, the case where the groove portion 13 in which the connecting portion 6 of the cap 4 is housed is provided in a straight line is illustrated, but the shape and the number of the groove portions are not limited to this. For example, the number of grooves may be the same as the number of first recesses 12, and a predetermined number of recessed grooves may be arranged side by side in the portion where the connecting portion 6 is located. Even with such a configuration, the cap 4 can be opened at once by relatively sliding the two parts 10 and 20 as in the above-described embodiment. The height dimensions and shapes of the wall portions 13a and 13b constituting the groove portion 13 may be set according to the continuous container.

例えば、連設容器の連結部が、容器本体の開口縁部から、列設方向Ｌ１に対して９０度方向に延設されている場合、折り返し線は列設方向Ｌ１と平行となる。このため、第一壁部１３ａにおける連結部と重なる部位（上記の山部１３ｃに相当する突出部）を、正面視で矩形状となるように形成してもよい。なお、突出部（例えば上記の山部１３ｃ）における連結部６の重なる辺は、必ずしも連結部６の折り返し線６ｅと平行でなくてもよいが、突出部と連結部６との重なる面積が大きい方が好ましい。同様に、押圧部２３におけるフランジ部４ｆと重なる辺２３ｅが仮想線Ｂと直交していなくてもよいが、押圧部２３とフランジ部４ｆとの重なる面積が大きい方が好ましい。 For example, when the connecting portion of the continuous container extends in the direction of 90 degrees with respect to the rowing direction L1 from the opening edge of the container body, the folding line is parallel to the rowing direction L1. Therefore, the portion of the first wall portion 13a that overlaps with the connecting portion (the protruding portion corresponding to the mountain portion 13c) may be formed so as to have a rectangular shape when viewed from the front. The overlapping side of the connecting portion 6 in the protruding portion (for example, the mountain portion 13c described above) does not necessarily have to be parallel to the folding line 6e of the connecting portion 6, but the overlapping area between the protruding portion and the connecting portion 6 is large. Is preferable. Similarly, the side 23e of the pressing portion 23 that overlaps the flange portion 4f does not have to be orthogonal to the virtual line B, but it is preferable that the area where the pressing portion 23 and the flange portion 4f overlap is large.

また、上述した実施形態では、容器本体２の個数と、第一凹部１２，第二凹部２２及び押圧部２３の各個数がいずれも８つである場合を例示したが、後者の個数（所定数）が、前者の個数以上であればよい。例えば、第一凹部１２，第二凹部２２及び押圧部２３の個数（所定数）が１２であるキャップ開放装置を使って、上記の８連キャップ付きＰＣＲチューブ１のキャップ２を開放することもできる。 Further, in the above-described embodiment, the case where the number of the container main body 2 and the number of each of the first recess 12, the second recess 22, and the pressing portion 23 are all eight is illustrated, but the latter number (predetermined number) is illustrated. ) May be greater than or equal to the former number. For example, the cap 2 of the above-mentioned PCR tube 1 with an 8-unit cap can be opened by using a cap opening device in which the number (predetermined number) of the first recess 12, the second recess 22, and the pressing portion 23 is 12. ..

上述した実施形態では、連設容器として、８連キャップ付きＰＣＲチューブ１を例示したが、キャップ開放装置に用いられる連設容器はこれに限られない。例えば、連設容器が市販の１２連キャップ付きＰＣＲチューブでもよいし、８個や１２個以外の多連キャップ付きＰＣＲチューブであってもよい。 In the above-described embodiment, the PCR tube 1 with an 8-unit cap is exemplified as the continuous container, but the continuous container used for the cap opening device is not limited to this. For example, the continuous container may be a commercially available PCR tube with a 12-cap, or a PCR tube with a multi-cap other than 8 or 12.

また、連設容器が市販品でなくてもよい。連設容器は、一列に連設されるとともに、上記の第一部品１０及び第二部品２０に挟まれる複数の容器本体と、各容器本体と連結されるとともに容器本体の開口を塞ぐキャップと、容器本体の開口縁部からキャップに向かって帯状に延設されるとともに屈曲可能な連結部と、を備えたものであり、キャップが、容器本体の開口よりも径方向外側に突出したフランジ部を有しており、このフランジ部が、容器本体が第一部品１０と第二部品２０との間に挟まれた状態で、これらの部品１０，２０が押圧部２３の突出方向Ｌ３に相対的にスライドされたときに押圧部２３により押圧されるものであれば、上述した実施形態と同様に、キャップ開放装置を用いて全てのキャップを一度に開放することができる。例えば、複数の容器本体の形状が全て同一でなくてもよいし、複数のキャップの向きや形状が全て同一でなくてもよい。 Further, the continuous container does not have to be a commercially available product. The continuous containers are arranged in a row, and have a plurality of container bodies sandwiched between the first component 10 and the second component 20, and a cap that is connected to each container body and closes the opening of the container body. It is provided with a connecting portion that extends in a band shape from the opening edge of the container body toward the cap and is bendable, and the cap has a flange portion that protrudes radially outward from the opening of the container body. This flange portion has the container body sandwiched between the first component 10 and the second component 20, and these components 10 and 20 are relative to the protruding direction L3 of the pressing portion 23. As long as it is pressed by the pressing portion 23 when slid, all the caps can be opened at once by using the cap opening device as in the above-described embodiment. For example, the shapes of the plurality of container bodies may not all be the same, and the orientations and shapes of the plurality of caps may not all be the same.
