For convenience of explaining the present invention, the dimensions of the liquid container (ampoule 1, vial 2) are defined as follows, and details will be described later.
That is, the maximum diameter of the liquid containers 1 and 2 is D1, and the maximum diameter of the lids 5 and 8 positioned above the necks 4 and 7 of the liquid containers 1 and 2 is D2. The minimum diameter of the neck portions 4 and 7 is D3, and in particular, the length from the innermost constricted portion 7A of the neck portion 7 of the liquid container (vial 2) to the outermost protruding portion 8A of the lid portion 8 positioned above the neck portion 7. This is D4.

Next, FIG. 8 is a perspective view of the medicine packaging container 11, in which a plurality of ampoules 1 or vials 2 are accommodated in the packaging container 11, and a barcode label 12 is attached to the outer wall surface thereof.
As shown in FIG. 8, in a medicine management system using a conventional barcode (barcode label 12), it is possible to display the barcode by simply pasting the barcode label 12 on the packing container 11. Since the amount of information is limited, there is a problem that a barcode or the like is not given to each medicine.
That is, in a hospital or the like, after unpacking the packaging container 11 sent from the manufacturer or wholesaler, necessary data for each drug, that is, the liquid container (ampoule 1, vial 2) is input manually. Is the current situation.
Therefore, there is a problem that an input error or the like may occur as well as troublesome data input (see Patent Document 1).

On the other hand, FIG. 9 is an explanatory plan view of an RFID (Radio Frequency Identification) tag 13, in which an IC chip 15 and an antenna 16 are provided on a film substrate 14 to enable wireless data communication, and from a barcode Since there is an advantage that there is a large amount of stored information, it is desirable to attach it to individual liquid containers (ampoules 1, vials 2) and use them for drug management.
However, the RFID tag 13 may interfere with data communication with the antenna of the reader / writer (not shown) in the management system due to a phenomenon such as absorption of electromagnetic waves in the vicinity of moisture and other liquids. There is no problem.
Furthermore, there is a problem that the efficiency of the data communication depends on the relative positional relationship between the antenna and the attitude of the RFID tag 13.
That is, the merchandise management system can be operated efficiently and stably by attaching RFID tags 13 to each of liquids or merchandise containers (ampoules 1 and vials 2) containing liquid medicines and other liquids, in particular. There is a problem that is difficult.

An RFID tag holder that enables appropriate and stable data communication with a liquid merchandise management system and its mounting method have been realized.

Next, the RFID tag holder 20 and its mounting method according to the first embodiment of the present invention will be described with reference to FIGS. However, the same parts as those in FIGS. 7 to 9 are denoted by the same reference numerals, and detailed description thereof will be omitted.
FIG. 1 is a plan view of an RFID tag holder 20, and the RFID tag holder 20 holds the RFID tag 13 (FIG. 9) attached to the liquid container (ampule 1, vial 2, FIG. 7). In addition, it enables data communication of information regarding the liquid contained in the liquid containers 1 and 2, and includes a closed arc-shaped main body 21, an inward protruding piece 22, and an RFID tag holding piece 23.
As a liquid container, the case of the vial 2 shown in FIG.

The closed arc-shaped main body 21 has a thin plate shape in which the inner peripheral portion 21A has an arc shape that can face the neck portion 7 of the vial 2 and the outer peripheral portion 21B has a rectangular shape (for example, a square shape), but no external force is applied. Then, this is comprised from the elastic synthetic resin material which has the rigidity which maintains original shape, and the penetration hole 24 which can penetrate the neck part 7 of the vial 2 is formed in the inner peripheral part 21A.
The inner peripheral portion 21A and the outer peripheral portion 21B can have any shape, for example, the inner peripheral portion 21A can be elliptical, depending on the shape of the vial 2 and the parallel form of the plurality of vials 2 in the packed state or reading state. The outer peripheral portion 21B can be formed in an arc shape or other arbitrary shape similar to the inner peripheral portion 21A.

The inward protruding piece 22 includes a base end portion 22A located at an arbitrary position in the inner peripheral portion 21A of the closed arc-shaped main body 21, and a free end portion 22B protruding inward of the insertion hole 24 from the base end portion 22A. The free end 22B can face the neck 7 of the vial 2.
The inward projecting piece 22 is desirably formed integrally with the closed arc-shaped main body 21 and the RFID tag holding piece 23. However, at least this may be formed of an elastic member so that the base end 22A can be elastically deformed. desirable.
The inward projecting piece 22 is formed with a tapered notch 25 and a slit 26 from its distal end toward the base end 22A of the inner peripheral portion 21A of the closed arc-shaped main body 21 from the free end 22B, The pair of left and right inwardly projecting pieces 22C can be elastically deformed in the length direction and the width direction (directions away from each other) with the slit 26 as a boundary.

The RFID tag holding piece 23 is formed on the outer peripheral portion 21B of the closed arc-shaped main body 21, and a tag base 27 for attaching the RFID tag 13 is provided on the tip end side.
Further, the RFID tag holding piece 23 has a length that allows the RFID tag 13 to be separated from the vial 2 by a predetermined interval, and has a shape that maintains the RRID tag 13 in a predetermined posture.
That is, in the illustrated example, the RFID tag holding piece 23 is positioned in the same plane as the plane to which the closed arc-shaped main body 21 and the inward protruding piece 22 belong in a state where no external force is applied.

Next, the length from the base end portion 22A of the inward protruding piece 22 to the inner peripheral portion 21A along the length direction of the inward protruding piece 22 in the inner peripheral portion 21A of the closed arc-shaped main body 21 is defined as L1.
When the inward protruding piece 22 is bent, the length from the projection end 22BB to the plane of the inner peripheral portion 21A of the free end 22B to the inner peripheral portion 21A along the length direction of the inward protruding piece 22 is L2. And
When the length from the free end portion 22B of the inward projecting piece 22 to the inner peripheral portion 21A of the closed arc-shaped main body 21 is L3, L3 <L2 <L1.

Further, D2 <L2 <D1 in relation to the maximum diameter D1 of the vial 2 already described in FIG. 7 and the maximum diameter D2 of the lid portion 8 located above the neck portion 7 of the vial 2.
That is, in order for the RFID tag holder 20 to be attached to and held by the vial 2, the length L 2 needs to be at least between the maximum diameter D 1 of the vial 2 and the maximum diameter D 2 of the lid portion 8.

More specifically, the minimum diameter D3 at the neck portion 7 of the vial 2 and the length D4 from the innermost constricted portion 7A at the neck portion 7 of the vial 2 to the outermost protruding portion 8A at the lid portion 8 located above the neck portion 7 are as follows. Relatedly, D3 <D4 <L2.
That is, when the RFID tag holder 20 is attached to the neck portion or the lid portion 8 of the vial 2 with an inclination, the length l2 of the vial 2 is It must be at least greater than the length D4 associated with the lid 8.
In addition, since D3 <D4, the RFID tag holder 20 is securely attached to the constricted portion of the neck 7.
Therefore, the RFID tag holder 20 can be attached and held even if the shape and size of the container body 6, the neck portion 7, and the lid portion 8 of the vial 2 are different.

In the RFID tag holder 20 having such a configuration, the insertion hole 24 of the RFID tag holder 20 can be inserted and attached to the neck portion 7 of the vial 2.
That is, FIG. 2 is a side view for explaining a state in which the RFID tag holder 20 is attached to the vial 2. First, as indicated by a virtual line in the drawing, the insertion hole 24 of the closed arc-shaped main body 21 is inserted into the insertion hole 24. The neck portion 7 is inserted to engage the inner peripheral portion 21A with the neck portion 7 (innermost constricted portion 7A).
Further, in the state where the RFID tag holder 20 is pulled forward so as to engage with the innermost constricted portion 7A in the neck portion 7, the inner peripheral portion 21A engaged with the innermost constricted portion 7A is a base point. As the RFID tag holder 20 is rotated downward in the figure, the inwardly projecting piece 22 is brought into contact with the lid portion 8 (the outermost projecting portion 8A) located at the upper portion of the neck portion 7 Let me know. Since the slit 26 is formed in the central portion of the inward projecting piece 22, the pair of left and right inward projecting pieces 22C are elastically deformed so as to be separated from each other, and the entire inner projecting piece 22 can be easily and easily deformed. It can be reasonable.

The RFID tag holder 20 is attached to the vial 2 so as to return to the original posture by the elasticity beyond the neck portion 7 from the lid portion 8 so as to face or engage the neck portion 7.

    FIG. 3 is a side view showing a front posture of the RFID tag holder 20 in a state in which the RFID tag holder 20 is attached to the vial 2, and as will be apparent with reference to FIG. The upper RFID tag 13 is located at a predetermined distance from the liquid medicine in the vial 2.

FIG. 4 is a side view showing a state in which a plurality of vials 2 each having an RFID tag holder 20 are placed on a reading table 29 in the medicine management system 28, and the RFID on the RFID tag holder 20 is shown. Since the tag 13 is separated from the liquid medicine in the vial 2 (container body 6) by a predetermined distance, the RFID tag 13 can reliably perform data communication with the reader / writer antenna 30 provided on the reading table 29. .
Further, by devising the mounting posture of the vial 2 of the RFID tag holder 20, the RFID tag 13 can be positioned in a posture suitable for this data communication. Specifically, by adjusting each dimension between the neck 7 of the vial 2 and the closed arc-shaped main body 21, the inward projecting piece 22, and the RFID tag holding piece 23 in the RFID tag holder 20, or each posture By adjusting so as to be inclined or twisted, the parallelism of the relative posture of the RFID tag 13 with respect to the reader / writer antenna 30 can be maintained as much as possible.
For example, as shown by a dotted line in FIG. 4, the RFID tag holding piece 23 is provided in a plane (a plane inclined slightly upward in the figure) different from the plane to which the closed arc-shaped main body 21 and the inward projecting piece 22 belong. The RFID tag 13 can take a relative posture that is more parallel to the reader / writer antenna 30.
Thus, when attaching the RFID tag holder 20 to liquid containers (ampoules 1 and vials 2) of different sizes, the parallelism between the reader / writer antenna 30 and the RFID tag 13 with a certain angle and interval is also provided. The communication performance of the RFID tag 13 is not impaired even if liquid is contained in the posture.

In the present invention, the inward projecting piece 22 and the RFID tag holding piece 23 can be provided at arbitrary relative positions around the closed arc-shaped main body 21.
That is, FIG. 5 is a plan view of the RFID tag holder 40 according to the second embodiment of the present invention. The RFID tag holder 40 is disposed around the closed arcuate main body 21 as opposed to the RFID tag holder 20. The inward protruding piece 22 and the RFID tag holding piece 23 are provided at positions opposite to each other (position shifted by 180 degrees).
As shown in the figure, the inwardly projecting piece 22 is provided at a position where the free end 22B of the inwardly projecting piece 22 faces the RFID tag holding piece 23 with the insertion hole 24 of the closed arc-shaped main body 21 therebetween.

FIG. 6 is a side view for explaining a state in which the RFID tag holder 40 is attached to the vial 2. First, as indicated by a virtual line in the drawing, the neck 7 of the vial 2 is inserted into the insertion hole 24 of the closed arc-shaped main body 21. And the free end portion 22B of the inward protruding portion 22 is engaged with the neck portion 7 (innermost constricted portion 7A).
Further, by rotating the RFID tag holder 40 downward in the drawing with the free end 22B engaged with the innermost constricted portion 7A in the neck 7 as a base point, the inner peripheral portion 21A of the closed arc-shaped main body 21 is moved. The inward projecting piece 22 is bent in contact with the lid portion 8 (the outermost projecting portion 8A) located at the upper portion of the neck portion 7.
Next, by rotating the entire RFID tag holder 40 in the direction of the container body 6 of the vial 2, the inward projecting piece 22 returns to its original posture due to its elasticity as shown by the solid line in FIG. The RFID tag holder 40 is attached to the vial 2 so as to face or engage with the vial 2.
Therefore, the inward projecting piece 22 in the insertion hole 24 of the closed arc-shaped main body 21 is engaged with the neck portion 7 of the vial 2, and the RFID tag 13 on the RFID tag holding piece 23 is predetermined from the liquid medicine in the vial 2. This position can be positioned at a position separated by an interval (position further away from the RFID tag holder 20 shown in FIG. 2), and is also suitable for the reader / writer antenna 30 of the medicine management system 28. This can be placed in a posture.

Thus, in the present invention, the RFID tag 13 can be disposed in an appropriate position and posture with respect to the liquid in the vial 2 (liquid container) and the reader / writer antenna 30 of the medicine management system 28. The shape and dimensions of the inward projecting piece 22 and the RFID tag holding piece 23 depend on the shape of the neck portion 7 of the vial 2 and the size of the inner peripheral portion 21A and the inward projecting piece 22 of the closed arc-shaped main body 21. The RFID tag 13 can be adjusted so that it can oppose or engage and can be separated from the liquid in the vial 2.
