This container can be used for analysis, testing, experiments, etc. in fields such as medical treatment, biochemistry, molecular biology, etc., and recording the specific information and related information of the sample in the container on the RFID tag Can do.

  It is known to record the specific information and related information of the sample in the container on the IC chip sealed in the container body (Patent Document 1). In Patent Document 1, the IC chip is embedded in the container body. Specifically, when the container body is molded, an IC chip is embedded in the container body.

  In the sample storage minitube of Patent Document 2, a spindle-shaped connection recess is provided at the lower end of the tube body (container body), and an IC tag storage section (tag holder) in which an IC tag is incorporated in the connection recess is provided. It is detachably engaged and connected. The tag holder is a resin molded product that is integrally provided with a disc-shaped base and a spindle-shaped connecting protrusion that protrudes from the upper surface of the base, and is provided on the lower surface of the base so as to open downward.

JP 2001-340426 A (paragraph number 0011, FIG. 1) Japanese Patent Laying-Open No. 2005-257573 (paragraph number 0044, FIG. 4)

  According to the form of Patent Document 1 in which an IC chip is sealed at the bottom of the container body, a larger amount of data can be stored in the IC chip, and further, data rewriting and new data can be added easily. . However, in Patent Document 1, the IC chip is embedded in the bottom wall of the container body, and it is not planned to separate and collect the IC chip from the container body. For this reason, there is a waste of resources that the IC chip is also discarded at the time of disposal of the container body.

  In that respect, in Patent Document 2, since the tag holder is configured to be detachable from the container body, an IC tag or the like included in the tag holder can be reused. That is, according to the form of Patent Document 2, the tag holder can be separated and collected when the container main body is discarded, and the tag holder and the IC tag included in the tag holder can be reused.

  However, in Patent Document 2, the tag holder is composed of a disk-shaped base portion and a spindle-shaped connecting protrusion projecting on the upper surface of the base portion. Therefore, when receiving a large external force such as centrifugal force, The tag holder may rotate along the inner surface of the connection recess. For this reason, due to such rotation, the connecting convex portion is worn and the mounting force with respect to the container main body is reduced, and as a result, the tag holder may be carelessly separated / dropped from the container main body. That is, in the form of Patent Document 2, there is a problem in that wear of the connecting convex portion due to the rotation of the tag holder occurs, the mounting force on the container body is easily reduced, and the number of reuse of the tag holder is reduced. .

  The object of the present invention is to wear the tag holder due to the rotation of the tag holder even when subjected to external force such as centrifugal force in a container with an RFID tag in which the tag holder is configured to be detachable from the container body. Therefore, it is possible to maintain the mounting force of the tag holder on the container body over a long period of time, and therefore to provide a container with an RFID tag that can increase the number of times the tag holder is reused.

  A container with an RFID tag according to the present invention is disposed inside a container main body 1 made of a plastic molded product, a tag holder 3 detachably attached to a connecting portion 13 at the bottom of the container main body 1, and the tag holder 3. An RFID tag 4 is provided. The tag holder 3 is made of a hollow container-like plastic molded product integrally provided with a bottom wall 21 and a peripheral wall 22. Between the connecting portion 13 of the container body 1 and the peripheral wall 22 of the tag holder 3, a press-fit groove 31 and a press-fit projection 32 are provided to press-fit and hold the tag holder 3 in a mounted state. A rotation restricting structure that engages with each other to restrict the rotation of the tag holder 3 is provided at the press-fitting engagement portion between the connecting portion 13 and the peripheral wall 22.

  A press-fitting groove 31 is formed in the inner surface of the peripheral wall 22 to be recessed, and a press-fitting projection 32 is formed to bulge out on the peripheral surface of the connecting portion 13.

  The rotation restricting structure includes a plurality of restricting ribs 14 projecting from the peripheral surface of the connecting portion 13 and a plurality of slits 25 formed on the peripheral wall 22 corresponding to the restricting ribs 14 and opened at the upper ends.

  Facing the base end of the press-fitting protrusion 32 of the connecting portion 13, the downwardly tapered tapered cylindrical portion 12 is formed. In a state where the tag holder 3 is press-fitted and attached to the connecting portion 13, an operation space S for removing and operating the tag holder 3 is secured between the tapered tube portion 12 and the opening end surface of the tag holder 3.

  Each of the press fitting groove 31 and the press fitting protrusion 32 is formed in a partial spherical shape. The regulating rib 14 and the slit 25 are arranged in a cross shape.

  On the upper side of the connecting portion 13 in the container main body 1, a main body cylinder portion 11 for storing contents is provided. The entire tag holder 3 attached to the connecting portion 13 is set to be inside the outline of the main body cylinder portion 11 in plan view. The outer surface of the bottom wall 21 of the tag holder 3 is formed as a flat surface.

  The tag holder 3 is molded with a polyamide resin containing a glass filler.

  Each regulating rib 14 is formed to the lower end of the connecting portion 13.

  In the present invention, since the tag holder 3 is detachably attached to the connecting portion 13 at the lower part of the container body 1, the tag holder 3 can be detached from the container body 1 and reused. Consumption costs can be reduced. In addition, since the RFID tag 4 is arranged inside the tag holder 3, the RFID tag 4 is not exposed, and therefore durability during use of the RFID tag 4 can be improved. In addition, a press-fit groove 31 and a press-fit projection 32 that hold the tag holder 3 in a press-fitting engagement with each other between the connecting portion 13 of the container body 1 and the peripheral wall 22 of the tag holder 3. Since the tag holder 3 is provided, the tag holder 3 can be firmly attached to the container body 1. Therefore, the tag holder 3 and the RFID tag 4 are inadvertently separated from the container body 1 in a situation where the container with the RFID tag is rotated at a high speed by the centrifuge and a large centrifugal force acts on the tag holder 3. Can be prevented. This means that if the container with an RFID tag according to the present invention is used, a centrifugal separation process can be performed at a higher rotational speed than before, and the process can be completed in a short time.

In addition, according to the present invention, the rotation restricting structure that engages each other and restricts the rotation of the tag holder 3 is provided between the connecting portion 13 of the container body 1 and the peripheral wall 22 of the tag holder 3. Further, it is possible to prevent the tag holder 3 from rotating with respect to the container body 1 during the centrifugation and the peripheral wall 22 and the connecting portion 13 from being worn. Therefore, it is possible to prevent the engagement force of the peripheral wall 22 with respect to the connecting portion 13 from being lowered and increase the number of times the tag holder 3 is reused.
In the present invention, since the tag holder 3 is a hollow container-shaped plastic molded product integrally provided with the bottom wall 21 and the peripheral wall 22, the weight of the tag holder 3 can be reduced. The centrifugal force acting on the tag holder 3 at the time of centrifugation is proportional to the mass of the tag holder 3. Therefore, the influence of the centrifugal force can be reduced by the amount that the tag holder 3 is lightened, and the tag holder 3 can be reliably prevented from being separated from the container body 1.

  Since the press-fitting groove 31 is formed in the peripheral wall 22 of the tag holder 3 and the press-fitting protrusion 32 is formed to bulge in the connecting portion 13 of the container body 1. The tag holder 3 can be further reduced in weight by the volume of the press-fit groove 31. Therefore, it is possible to reduce the influence of the centrifugal force and more reliably prevent the tag holder 3 from being separated from the container body 1 during the centrifugation.

  The rotation restricting structure can be composed of a plurality of restricting ribs 14 protruding from the peripheral surface of the connecting portion 13 and a plurality of slits 25 formed in the peripheral wall 22 corresponding to the restricting ribs 14. According to this, the rotation of the tag holder 3 can be reliably restricted by the engagement between the restriction rib 14 and the slit 25, and the rotation restriction structure is provided when the tag holder 3 is attached to and detached from the connecting portion 13. The tag holder 3 can be easily attached and detached without causing an obstacle. Furthermore, the weight of the tag holder 3 can be reduced as compared with the case where the regulation ribs 14 are provided on the peripheral wall 22, so that the influence of centrifugal force is reduced and the tag holder 3 is more reliably separated from the container body 1 during centrifugation. Can be prevented.

  A tapered tapered cylindrical portion 12 is formed so as to face the proximal end of the press fitting protrusion 32 of the connecting portion 13, and the tag holder 3 is removed between the tapered cylindrical portion 12 and the opening end surface of the tag holder 3. Therefore, it is possible to secure an operation space S for the purpose. According to this, since the tag holder 3 can be accurately removed from the connecting portion 13 by placing a fingertip or a detachable tool on the upper end of the peripheral wall 22 via the operation space S, the tag holder 3 can be removed during the removal operation. Damage can be reliably prevented. Therefore, it is possible to prevent the tag holder 3 from engaging with the connecting portion 13 from decreasing and to increase the number of times the tag holder 3 is reused.

  If each of the press fitting groove 31 and the press fitting protrusion 32 is formed in a partial spherical shape, stress does not concentrate at one place in the vertical direction of the connecting portion 13 and the peripheral wall 22, and the connecting portion 13 and the peripheral wall 22 are bent. Damage can be prevented. Further, since the regulating ribs 14 and the corresponding slits 25 are arranged in a cross shape, the peripheral wall 22 of the tag holder 3 is divided into four partial arc-shaped partial walls by the slits 25, and two slits 25 are provided. Compared to the case of three, the expansion deformation of the partial wall can be facilitated. Therefore, the attachment / detachment operation of the tag holder 3 with respect to the connection part 13 can be performed simply. After the tag holder 3 is formed, it can be easily released.

  When the entire tag holder 3 is within the outline of the main body cylinder portion 11 of the container body 1 in a plan view, the container with the RFID tag with the tag holder 3 attached to the connecting portion 13 is replaced with a tube rack or the like. Can be accommodated without any problem. If the outer surface of the bottom wall 21 of the tag holder 3 is formed as a flat surface, the RFID tag-equipped container with the tag holder 3 attached to the connecting portion 13 can be made to stand by a stable posture with the bottom wall 21 as a leg. It is possible to improve handling of the RFID tag-equipped container.

  When the tag holder 3 is molded from a polyamide resin containing a glass filler, the rigidity of the tag holder 3 can be increased, and the engaging force of the tag holder 3 with respect to the connecting portion 13 can be increased. It can be well prevented from separating. Further, by adjusting the content of the glass filler, the rigidity of the tag holder 3 can be adjusted, and the engagement force of the tag holder 3 can be set according to the required resistance against centrifugal force.

  If the regulation rib 14 is formed to the lower end of the connection part 13, the container main body 1 of the state which removed the tag holder 3 can be made to stand by making the connection part 13 and each regulation rib 14 into a leg body. Moreover, the attitude | position of the container main body 1 can be stabilized compared with the case where only the connection part 13 is used as a leg, and the handleability of the container with an RFID tag can be improved.
