  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to the following embodiment at all, In the range of the objective of this invention, it can add and change suitably.

[Test container]
As illustrated in FIG. 1, the test container 1 according to this embodiment includes a container body 4 having an opening 3 at one end and a lid 2 that closes the opening 3, and the lid 2 and the container The body 4 can be attached to and detached from each other by a screw lid mechanism, and the lid 2 has a distance from the center of rotation C to the outer periphery of the lid when viewed from the direction of the central axis of rotation of the screw lid mechanism. It has a configuration in which a finger hook portion 7 having a long part 5 and a part 6 having a short distance and having a surface connecting the part 6 having a short distance and the part 5 having a long distance is provided. In this embodiment, viewing from the direction of the central axis of rotation of the screw lid mechanism means that the direction of extension of the central axis of rotation is aligned with the direction of the line of sight from the extension of the central axis of rotation of the screw lid mechanism. Is shown. That is, it can be paraphrased as a case of observing from the direction opposite to the upper surface of the lid 2.

  In the present embodiment, the screw lid mechanism is a mechanism that works for opening and closing, usually called a “screw lid”, a “screw cap”, or the like. That is, the container body 4 is provided with a spiral projection along the outer peripheral surface of the opening 3, and the inner surface of the lid 2 is spirally fitted to the spiral projection provided along the outer peripheral surface of the opening 3. This means a mechanism for opening and closing the opening 3 of the container main body 4 by providing a groove and rotating the lid 2.

  The center of rotation C of the screw lid mechanism means the position on the axis of rotation when the lid 2 is rotated to open and close the opening 3 of the container body 4 in the above-described screw lid mechanism. Yes. When viewed from the direction of the central axis of rotation of the screw lid mechanism of the lid 2, it may be said that the intersection of the central axis of rotation and the upper surface of the lid 2. Accordingly, when viewed from the direction of the central axis of rotation of the screw lid mechanism of the lid 2, when the lid is opened / closed, the screw 2 rotates about the center C of rotation of the screw lid mechanism.

  In addition, when different contents are used in a plurality of test containers 1 at the same time, contamination of the contents may occur due to a wrong combination of the lid 2 and the container body 4. In order to prevent the lid 2 and the container main body 4 from being mixed, at least a part of the container main body 4 and at least a part of the lid 2 are colored in advance, or the same place where the lid 2 and the container main body 4 are easy to see. A number may be engraved.

  Further, the lid 2 and the container main body 4 are connected so that the lid 2 is rotatable, so that contamination of contents due to a wrong combination of the lid 2 and the container main body 4 can be prevented.

  As a use of the test container in the present embodiment, it can be used for mixing, diluting, stirring, centrifuging, and storing liquids, reagents, specimens, and the like during a biochemical test. More specifically, the test container 1 is used as a test tube, a microtube, a cryopreservation tube, or a centrifuge tube that is a container for centrifugation.

[Container body]
As illustrated in FIG. 1, the container body 4 according to the present embodiment is a mechanism having an opening 3 at one end.

  That is, the container body 4 has a shape as a container having a storage portion for storing a liquid, a reagent, a sample, and the like when used for mixing, diluting, stirring, centrifuging, and storing a liquid, a reagent, a sample, and the like. doing. An opening 3 for taking in and out liquids, reagents, specimens and the like is provided in the upper part of the storage unit. Along the outer peripheral surface of the opening 3 of the container main body 4, a spiral protrusion is provided for the purpose of enabling fitting with the lid 2 described later, and forms a part of the screw lid mechanism.

  Although the internal shape which forms the accommodating part of the container main body 4 is not restrict | limited in particular, When using as a test tube, a microtube, a cryopreservation tube, and a centrifuge tube, it is preferable that it is a cylindrical shape. An opening 3 for taking in and out liquids, reagents, specimens and the like is provided in the upper part of the storage unit. The bottom part of the storage part is closed to form a closed bottom part 8.

  By making the internal shape cylindrical, the contents can be smoothly rotated during stirring, mixing, and centrifugation, and the test container 1 in which stirring, mixing, and centrifugation efficiently proceed can be obtained. Moreover, the residue of the contents can be minimized when the contents are taken out.

  The closed bottom 8 is preferably a closed bottom 8 having a diameter smaller than the diameter of the cylinder, particularly when used as a centrifuge tube. As a typical example of such a shape, it is suitable that the closed bottom portion 8 has a shape called a conical type or a round type. By setting it as such a shape, collection | recovery of a sediment becomes easy.

  The external shape of the container body 4 is not particularly limited except that a spiral protrusion is provided along the outer peripheral surface of the opening 3 of the container body 4. Often, products with an emphasis on cost are cylindrical with a uniform thickness along the internal shape.

  The external shape of the container body 4 may be uneven so as to improve the fit when the test container 1 is held and can be gripped stably. Further, a minute unevenness for preventing slipping is provided on a part or the whole of the outer shape of the container body 4 so that the container body 4 rotates with the lid 2 in the hand when the lid 2 is opened and closed, or the opening and closing is not hindered. The external shape of the container body 4 may be a polygonal column shape except for the portion where the screw mechanism is formed.

  Moreover, the external shape of the container main body 4 may be a self-supporting type with the external shape as a foot, as in the closed bottom portion 8 in FIG. It may be formed.

  The material forming the container body 4 is not particularly limited. In the case where the container body 4 also functions as a centrifuge tube, the material forming the container body 4 only needs to be rigid enough not to be deformed by the centrifugal force generated by the rotation of the centrifuge, and may be plastic, glass, or glass. Ceramics or the like is used. Usually, it is a plastic molded article using polypropylene, polystyrene, polycarbonate, polyethylene terephthalate or the like. Among these, it is preferable that the container body 4 is formed of a transparent material in that the inside of the container body 4 can be observed.

  The capacity of the container body 4 in this embodiment is about 2 to 1000 ml in practical use.

  In the case of a capacity of 35 ml, the dimensions of the container body 4 are preferably 75 mm in height, 27 mm in inner diameter, and 1 mm in thickness, because the container body 4 has such rigidity as not to be deformed by the centrifugal force generated by the rotation of the centrifuge.

  In the manufacturing method of the container body 4, the raw material resin in a pellet state is put into an injection molding machine, and the raw material resin is melted in the injection molding machine. And this molten resin is filled in a metal mold | die, and the container main body 4 can be formed by the injection molding method. In terms of reducing production efficiency and adhesion of foreign matters (endotoxin, DNA degrading enzyme, etc.) during production, it is preferable for a biochemical container to shorten the production process and omit the assembly process as much as possible.

[lid]
The lid 2 according to the present embodiment is detachable from the container body 4 by a screw lid mechanism and closes the opening 3. The lid 2 has a portion 5 having a long distance from the center C of rotation to the outer periphery of the lid 2 when viewed from the direction of the central axis of rotation of the screw lid mechanism, and a portion 6 having a short distance. A finger hook 7 having a surface connecting the part 6 with the short distance and the part 5 with the long distance is provided.

  That is, the lid 2 in the present embodiment is provided with a spiral groove on the inner surface so as to be able to be fitted with a spiral protrusion provided along the outer peripheral surface of the opening 3, and by rotating the lid, the container body 4 A screw lid mechanism for opening and closing the opening 3 is formed. That is, it has a function as a screw cap or a screw cap for the container body 4 in general terms.

  Furthermore, as illustrated in FIGS. 2, 3, and 4, the appearance of the lid 2 is such that the distance from the center of rotation C to the outer periphery of the lid is long when viewed from the direction of the central axis of rotation of the screw lid mechanism. 5 and a portion 6 having a short distance from the rotation center C of the screw lid mechanism to the outer periphery of the lid when viewed from the direction of the central axis of rotation of the screw lid mechanism. Further, when viewed from the direction of the central axis of rotation of the screw lid mechanism, a portion 5 (hereinafter referred to as a long distance portion 5) having a long distance from the rotation center C of the screw lid mechanism to the outer periphery of the lid, and the screw lid mechanism When viewed from the direction of the central axis of rotation, the finger-holding portion 7 is provided with a surface that connects a portion 6 (hereinafter referred to as the short-distance portion 6) having a short distance from the rotation center C to the outer periphery of the lid. .

In other words, if the distance from the rotation center C of the screw lid mechanism to the long distance portion 5 is Rb, and the distance from the rotation center C of the screw lid mechanism to the short distance portion 6 is Rs,
Rb> Rs
The distance Rb from the rotation center C of the screw lid mechanism to the long distance portion 5 and the distance Rs from the rotation center C of the screw lid mechanism to the short distance portion 6 are sufficiently large when opening and closing. It is desirable that the finger-hanging portion 7 has a difference that can be formed.

  Further, the larger the difference between the distance Rb from the rotation center C of the screw lid mechanism to the long distance portion 5 and the distance Rs from the rotation center C of the screw lid mechanism to the short distance portion 6, the less force is required for opening and closing. .

  That is, the screw lid which is a commercially available product, that is, a screw having the same distance Rb from the rotation center C to the long distance portion 5 and the distance Rs from the rotation center C to the short distance portion 6 of the screw lid mechanism. Even if the lid is applied with a finger when the lid 2 is opened / closed, the pressing force of the finger passes through the central axis of rotation of the screw lid mechanism, so it does not act as a force for opening / closing the lid, and the lid is rotated separately. It is necessary to apply power to make it happen. Therefore, when opening and closing the lid 2 with one hand, it is an extremely difficult operation of holding and rotating the lid 2 while holding the container body 4.

  On the other hand, in the test container 1 according to the present embodiment, when the lid 2 is opened and closed, a finger is placed on the finger hook 7 and the finger hook 7 is pressed with the finger, whereby the finger hook 7 is set with the rotation axis of the screw lid mechanism as the rotation axis. Since the force applied to is applied off the central axis of rotation of the screw lid mechanism, the lid 2 works to open and close. Accordingly, when the lid 2 is opened and closed with one hand, the container body 4 is held and the finger hooking portion 7 of the lid 2 is pushed.

  Actually, the distance Rs from the rotation center C of the screw lid mechanism to the short distance portion 6 only needs to be a distance that can maintain the strength as the screw lid, and the minimum value thereof is the screw lid of the container body 4. The screw lid which is a current commercial product made according to the mechanism, that is, the distance Rb from the rotation center C of the screw lid mechanism to the long distance portion 5 and the rotation center C to the short distance portion 6 of the screw lid mechanism. The distance Rs may be equal to or larger than the outer diameter of the screw lid. However, if the distance Rs from the rotation center C of the screw lid mechanism to the short distance portion 6 becomes too long, the lid 2 becomes too large as the test container 1 and the test container 1 becomes unstable. Moreover, the storage area of the test container 1 when the lid is closed is not desirable.

  Accordingly, the distance Rs from the rotation center C of the screw lid mechanism to the short distance portion 6 is the screw lid which is a commercially available product made according to the screw lid mechanism of the container body 4, that is, the screw lid mechanism. It is preferable that the distance Rb from the center C to the long distance portion 5 and the distance Rs from the rotation center C to the short distance portion 6 of the screw lid mechanism are substantially equal to the outer diameter of the screw lid.

  The longer the distance Rb from the rotation center C of the screw lid mechanism to the long distance portion 5, the less force is required to open and close the lid 2. However, if the distance Rb is too long, the lid 2 will not be too large as the test container 1. A stable test container 1 is obtained. In addition, the storage area of the test container 1 when the lid 2 is attached is undesirably large. Also, considering the case of opening and closing the lid 2 with one hand, the distance that the finger can be hung is not so long. Therefore, even if the length is too long, the finger does not reach that point, so the range in which the effect of opening and closing with a weaker force can be obtained is limited.

  Therefore, the distance Rb from the rotation center C of the screw lid mechanism to the long distance portion 5 is about 1.4 to 2.0 times the distance Rs from the rotation center C to the short distance portion 6 of the screw lid mechanism. Is preferred.

  Having a surface connecting the short distance portion 6 and the long distance portion 5 indicates that the short distance portion 6 and the long distance portion 5 are continuously formed adjacent to each other. A part of the surface that extends from the short distance portion 6 to the long distance portion 5 is the finger hook portion 7. The finger-hanging portion 7 is a portion that applies force when the lid 2 of the test container 1 of the present embodiment is opened and closed. The applied force is naturally applied off the central axis of rotation of the screw cover mechanism by putting the finger on the finger-hanging portion 7 and pushing it, and the cover 2 can be opened and closed.

  The finger-hanging portion 7 does not necessarily require an area for receiving the entire finger, and it is sufficient that a force is applied by hooking a part of the finger. Therefore, the distance Rs from the center of rotation C of the screw lid mechanism to the short distance portion 6 and the distance Rb from the center of rotation C of the screw lid mechanism to the long distance portion 5 are about 3 mm. Moreover, it does not need to be provided in the whole outer peripheral height direction of the lid | cover 2, and may be provided only in a part of outer peripheral height direction of the lid | cover 2.

  By providing a plurality of the long distance part 5 and the short distance part 6 each, when the test container 1 is picked up, it is possible to hang a finger on the finger-holding part 7 without changing the holding container. It becomes possible to work on.

  When there are a plurality of the long distance portions 5 and the short distance portions 6, the distance Rb from the rotation center C of the screw lid mechanism to the long distance portion 5 or the short distance portion 6 from the rotation center C of the screw lid mechanism. It is not necessary for the distances Rs to be the same. However, considering the case where the test container 1 is used as a centrifuge tube or the case where it is a self-supporting type, it is preferable that the weight is balanced.

  Therefore, it is desirable that the distance Rb from the rotation center C of the screw lid mechanism to the long distance portion 5 and the distance Rs from the rotation center C of the screw lid mechanism to the short distance portion 6 have the same value. The shape of the lid as viewed from above is preferably line symmetric with respect to an axis of symmetry passing through the center of rotation C of the screw lid mechanism or point symmetric with respect to the center of rotation C of the screw lid mechanism. . By doing so, the center of rotation C and the center of gravity of the screw lid mechanism coincide with each other, and the test container 1 having a good weight balance is obtained.

  Further, fine protrusions and irregularities can be formed on the outer peripheral portion of the lid as a non-slip on the whole or a part thereof. In particular, it is preferable to form a non-slip on the finger-hanging portion 7 because it is easy to apply a force stably when the finger is hung.

  The material for producing the lid is not particularly limited. What is necessary is just to select suitably in light of the intended purpose of the test container 1. Moreover, you may combine a some material as needed, such as the inner side and outer peripheral part which a content contacts.

  When the test vessel 1 also functions as a centrifuge tube, the lid 2 only needs to be rigid enough not to be deformed by the centrifugal force generated by the rotation of the centrifuge, and plastic such as polyethylene, polypropylene, ABS resin, polycarbonate, etc. Consists of

  The size of the lid 2 of the test container 1 according to this embodiment may be appropriately determined according to the size of the opening 3 of the container body 1. As an example, in the case of a volume of 35 ml, the lid 2 has a cylindrical shape with a height of 10 mm, an inner diameter of 28 mm, and a short distance portion 6 having a thickness of 1 mm.

  The manufacturing method of the lid 2 of the test container 1 is similar to the molding method of the container body 4 described above, in which a raw material resin in a pellet state is charged into an injection molding machine, and the raw material resin is melted in the injection molding machine. And this molten resin is filled in a metal mold | die, and the lid | cover 2 can be formed by the injection molding method.

<First embodiment>
As a specific shape of the lid 2 of the first embodiment, as illustrated in FIGS. 1 and 2, the lid 2 has a square outer periphery when viewed from the central axis direction of the rotation of the screw lid mechanism of the lid 2. It may be. In this embodiment, there are four long distance portions 5 and six short distance portions 6 alternately, and the distance Rb from the rotation center C of the screw lid mechanism to the long distance portion 5 is the rotation center C of the screw lid mechanism. Is 1.4 times the distance Rs from the short distance portion 6 to the short distance portion 6.

  When the lid 2 is opened / closed, the lid 2 can be opened / closed by applying a force so that a finger is put on the finger-hanging portion 7 which is a surface of the long distance portion 5 and the short distance portion 6. It is not necessary to be aware of a difficult operation with one hand, such as holding the container body 4 of the test container 1 and holding the lid 2, and can be easily opened and closed.

  In addition, since the finger-pushing portion 7 is formed in four directions in each of the parts to be pushed when opening and the parts to be pushed when closing, the finger-holding part 7 can be placed at an appropriate position without being aware of the direction of holding. Since the finger-hanging portion 7 exists, it is possible to work efficiently.

<Second Embodiment>
As a specific shape of the lid 2 of the second embodiment, as illustrated in FIG. 3, the long distance portion 5 and the finger hook portion 7 may be provided in the form of a push plate in two symmetrical directions. In this embodiment, there are two long distance portions 5, and a portion excluding a portion necessary for forming the long distance portion 5 is a short distance portion 6.

  When the lid 2 is opened / closed, the lid 2 can be opened / closed by applying a force so that the finger-hanging portion 7 is pushed and pushed. It is not necessary to be aware of a difficult operation with one hand, such as holding the container body 4 of the test container 1 and holding the lid 2, and can be easily opened and closed.

  This embodiment is easy to apply even when the diameter of the test container 1 is short and thin. Further, in the embodiment, there are two long distance portions 5, and the finger-hanging portion 7, which is the surface of the long distance portion 5 and the short distance portion 6, is pressed in two directions each for a portion to be pressed when opening, However, the long distance portion 5 may be provided in any number of three and four locations.

  However, if the number increases too much, it is difficult to place a finger on the finger rest portion 7, so the long distance portion 5 has about 1 to 6 locations, that is, the finger rest portion 7 has 1 portion to be pressed when opening and 1 portion to be pressed when closing. It is preferable that six directions are formed from the direction.

  Since the long distance portion 5 and the finger hook portion 7 are formed in a plurality of directions, any finger hook portion 7 is present at an appropriate position without being aware of the orientation of the liquid handling. Therefore, it becomes possible to work efficiently.

As shown in FIG. 4, one of the modifications according to the present embodiment may be provided so that the part that forms the finger hook portion 7 can be removed. For example, it can be realized by making the finger-hanging part 7 removable from the lid 2.

  When the lid 2 is viewed from the direction of the central axis of rotation of the screw lid mechanism during storage, it is possible to reduce the area required for storage by removing a portion having a large distance from the rotation center C to the outer periphery of the lid. Become. When the test container 1 is used as a storage container, it is particularly effective when a space that can be stored, such as a thermostatic bath, is limited.

  Moreover, in the case of liquid handling, workability | operativity can be improved by attaching the finger hook part 7. FIG.
