[2. Action, effect]
Here, a procedure for opening the cap 4 of the PCR tube 1 by the above-described cap opening device will be described. First, the PCR tube 1 is set to the first part 10 while inserting the tip of each protrusion 12 of the first part 10 into the space 6 of the PCR tube 1. At this time, the main body connecting portion 3 is placed (contact arrangement) on one end face 12 a of the protrusion 12, and the cap connecting portion 5 is placed (contact arrangement) on the other end face 12 b of the protrusion 12.

  Next, the second part 20 is combined so as to sandwich the PCR tube 1 with the first part 10. At this time, by inserting the cylindrical portion 23 of the second part 20 into the pin 13 of the first part 10, the two parts 10 and 20 are aligned. As a result, as shown in FIGS. 4 (a), (b) and 5 (b), the holes 22 are positioned directly above the respective protrusions 12. As shown in FIG. Then, as shown by a white arrow in FIG. 5A, the two parts 10 and 20 are approached so as to sandwich the PCR tube 1. Here, since the two parts 10 and 20 can be moved only in the second direction L2 by the pin 13 and the cylindrical portion 23, the PCR tube 1 can be easily inserted without any positional deviation. .

  When force is applied to the base portion 11 and the pressing portion 21 so that the distance between the first component 10 and the second component 20 (the distance in the second direction L2) becomes short, the main body connecting portion 3 becomes one of the protrusions 12 The end face 12a is pushed toward the pedestal 11, and the cap connector 5 pushes the other end face 12b of the projection 12 toward the pedestal 11. Thereby, as shown by a thick arrow in FIG. 5A, the main body connecting portion 3 and the cap connecting portion 5 receive the reaction force from each of the two end faces 12a and 12b of the protrusion 12, and the two connecting portions The distance between 3 and 5 can be expanded.

  That is, by sandwiching the PCR tube 1 with the two parts 10 and 20, the projection 12 separates the main body connecting portion 3 and the cap connecting portion 5 from each other, so that the container main body 2 and the cap 4 are separated. As shown in b) all caps 4 are released at one time. The opened container body 2 is received by the concave surface of the reinforcing portion 14.

  Therefore, according to the above-described cap opening device, all the caps 4 can be easily opened at one time, and work efficiency can be enhanced. In addition, because of its compact configuration, it is possible to work on the palm or finger. In other words, the cap 4 of the PCR tube 1 can be opened even in a place where there is no desk or work bench, so that it can be used regardless of the working environment. Therefore, for example, when sterilizing the used PCR tube 1 with a sterilizer, put a hand inside the sterilizer pot (chamber) and perform an operation of opening the cap 4 of the PCR tube 1 in the pot. Can.

  Further, since the projection 12 described above is formed in a plate-like isosceles triangle, when a force is applied so as to sandwich the PCR tube 1 between the pedestal 11 and the pressing portion 21, the main body connecting portion 3 and the cap The connecting portion 5 can be pushed more evenly by the protrusion 12. For this reason, the cap 4 is easily released, and the working efficiency can be enhanced.

  Further, in the cap opening device described above, one of the two joint portions 13 and 23 is provided as the pin 13 and the other is provided as the cylindrical portion 23 having the through hole 23a. Therefore, the two components 10 and 20 can be aligned simply by inserting the pin 13 into the cylindrical portion 23. In addition, since the two parts 10 and 20 can not move in any direction other than the axial direction (second direction L2) of the pin 13 (the movement direction is restricted), the PCR tube 1 can be easily pinched by the two parts 10 and 20 Can improve work efficiency.

  The pedestal surface 11a and the pressing surface 21a described above are formed in a rectangular shape congruent with each other, the protrusion 12 and the hole 22 are juxtaposed on one long side, and two mating portions on the other long side 13,23 are provided. Therefore, while the PCR tube 1 is set to the protrusion 12 positioned on one long side, the position of the pressing portion 21 with respect to the pedestal 11 is set by the two joining portions 13 and 23 positioned on the other long side. Can be adjusted. Thereby, the workability can be improved.

  As shown in FIG. 4 (b), the above-described protrusion 12 is formed so that the tip thereof exceeds the imaginary straight line K, so the PCR tube 1 is stably set to the first component 10. it can. Thereby, the workability can be improved.

  Moreover, since the reinforcement part 14 which connects the base end parts of the adjacent projection part 12 in the 1st component 10 is provided, the rigidity of the projection part 12 can be improved. Furthermore, the upper surface of the reinforcing portion 14 is recessed, and also has a function of receiving the container body 2 when all the caps 4 are opened. In other words, the cap opening device can be made more compact by combining the function of increasing the rigidity of the protrusion 12 and the function of receiving the container main body 2 after the cap 4 is opened in one site of the reinforcing portion 14. Can be

If it is the connection container 1 (for example, PCR tube) used for the cap opening apparatus mentioned above, it will be easy to open all the caps 4 irrespective of a working environment.
Moreover, if it is the cap open apparatus mentioned above, the cap 4 of commercially available cap isolation | separation type 8-repeat PCR tube 1 can be opened easily. Since the main body connecting portion 3 is separated from the opening edge portion 2 e of the 8-tuple PCR tube 1, the tip end of the protrusion 12 can be inserted between the main body connecting portion 3 and the cap connecting portion 5. Furthermore, since the main body connecting portion 3 connects the thick annular portions 2c to each other, the strength is higher than the other portions, and the container main body 2 is deformed even when a force is applied when the cap 4 is opened. There is nothing to do. Therefore, the cap 4 can be opened more easily and with less force.

[3. Other]
The configurations of the cap opening device and the continuous container 1 described above are an example, and are not limited to those described above.
For example, the first mating portion 13 may be provided as a cylindrical portion having a through hole, and the second mating portion 23 may be provided as a pin. Even with such a configuration, it is possible to obtain the same effect as that of the above-described embodiment. In addition, the 1st matching part 13 and the 2nd matching part 23 should just be a shape and arrangement | positioning which can position mutually, and are not restricted to the structure mentioned above.

  The shapes of the pedestal 11, the protrusion 12, and the first reinforcing portion 14 of the first component 10 described above are merely examples, and may not be the shapes described above. For example, the pedestal surface may have a shape different from that of the pressing surface, and the protrusion may not have a plate shape or an isosceles triangle shape. At least the tip of the protrusion can enter the space 6 between the adjacent container bodies 2, and one of the two end faces approaching each other toward the tip contacts the body coupling portion 3, and the other is The shape may be any shape that can contact the cap connection portion 5. Further, the reinforcing portion connecting the base ends of the adjacent protrusions may not be provided with a concave surface, and a site for receiving the container main body 2 with the cap 4 opened may be separately provided. In addition, for example, the base end portion of the protrusion may be formed thick and the reinforcing portion may be omitted. Further, wall portions provided along the row direction L0 are provided at both ends in the first direction L1 of the first part, and the open cap 4 and container body 2 are received by the wall portions of both ends, the first part It may be configured to be secured within.

  The shapes of the pressing portion 21 and the hole 22 of the second component 20 described above are merely examples, and may not be the shapes described above. For example, the shape of the hole and the arrangement thereof may be set according to the shape and arrangement of the protrusion. Further, the pressing portion having the pressing surface is not a thin plate as described above, but is formed in a thick plate shape (rectangular shape), and has a curved surface shape that accommodates a half circumference of the container body 2 on the pressing surface of the pressing portion. A (R-shaped) recess may be provided. Even with such a shape, it is possible to obtain the same effects as those of the embodiment described above. Also, if the pedestal 11 of the first part 10 is made rectangular like the pressing part, and the pedestal surface of this pedestal is provided with a curved surface (R-shaped) recess for accommodating the remaining half circumference of the container main body 2 Instead of the concave surface of the reinforcing portion 14 described above, the container body 2 in which the cap 4 is opened can be received by the upper and lower two recesses. In this case, it is preferable to design the shape in consideration of the distance of movement when the cap 4 is opened.

  Although the number of each of the container main body 2 and the cap 4 is eight and the number of each of the protrusions 12 and the holes 22 (predetermined number) is nine in the embodiment described above, for example, the containers at both ends The protrusions 12 and the holes 22 located on the side of the main body 2 may be omitted, and seven protrusions 12 and seven holes 22 may be provided. In addition, if the number (predetermined number) of each of the protrusions 12 and the holes 22 is larger than the number of each of the container main body 2 and the cap 4, the caps 2 of the cap-separating 8-tuple PCR tube 1 are all opened at one time. can do.

  In the embodiment described above, the cap separation type 8-tuple PCR tube 1 is exemplified as the connection container, but the connection container used in the cap opening device is not limited to this. For example, the continuous container may be a commercially available 12-piece PCR tube of cap separation type, or may be a multiple PCR tube of cap separation type other than 8 or 12 pieces. Moreover, although the PCR tube 1 mentioned above has the cap connection part 5 which connects the outer surface of the cover part 4a by two plate-like site | parts, The flange part which encloses the outer surface of the cover part 4a in each cap The cap connection portion may be provided to connect adjacent flange portions. This enhances the rigidity of the cap connection.

  Further, the continuous container may not be a commercially available product.
