Further, the radiation shield member transport container 1 of the present embodiment is a container in which the radiation shield member 100 as shown in FIG. 12 in which a syringe filled with a radioactive drug solution is inserted is housed inside the outer container 2. The radiation shield member 100 to be housed has been conventionally sold including a syringe and the like, and the one end side of the radiation shield member 100, from which the plunger 101 connected to the gasket in the syringe is projected, has a syringe shaft. Two wing-shaped holding members 102, 102 are formed that are orthogonal to the direction and extend in the diametrical direction of the syringe and face each other. It should be noted that when the radiation shield member 100 is stored in the radiation shield member transport container 1, the illustrated one is the plunger 101 and the injection needle portion 10 shown in FIG.
Although 3 is not attached, a radiation shield member with a plunger may be stored, in which case,
It goes without saying that the lid body is made according to the length and shape of the plunger.

As shown in FIGS. 2 and 7, an annular ridge 4 is formed on the outer peripheral surface of the outer container 2 at the open end thereof, as shown in FIGS. On the other hand, an annular groove 5 that engages with the annular protruding portion 4 is formed on the inner peripheral surface of the lid body 3 corresponding to the annular protruding portion 4 over the entire circumference thereof. The lid 3 is
By engaging the annular protrusion 4 and the annular groove 5, it is possible to attach / detach to / from the outer container 2 while maintaining hermeticity by a so-called snap-on method. Further, on the outer peripheral surface at the open end of the outer container 2, a mountain-shaped guide protrusion 8 having two sliding slopes 8a, 8a is disclosed, for example, as disclosed in Japanese Utility Model Laid-Open No. 55-170262. At regular intervals in the direction, in the present embodiment, it is formed at four places at 90 ° center angles.

Further, as shown in FIG. 7, a retaining ring groove 6 for mounting a retaining ring 12, which will be described later, is formed on the entire inner peripheral surface of the outer container 2 at the open end thereof. Furthermore, at one location on the bottom of the outer container 2, two plate members 7 are erected in parallel at a predetermined interval along the inner peripheral surface from the bottom plate 2a.

In such an outer container 2, as shown in FIGS. 8 to 10, a radiation shield container 9 having a cup shape is mainly shown.
Is installed. The radiation shield container 9 is made of, for example, a lead material, and shields the radiation emitted from the radioactive solution in the syringe housed in the outer container 2 and transmitted through the radiation shield member 100, and is substantially in the outer container 2. It has an outer diameter enough to contact the peripheral surface. When the radiation shielding container 9 is mounted in the outer container 2, the end surface 9a of the opening of the radiation shielding container 9 is slightly smaller than the end surface 2b of the opening of the outer container 2 as shown in FIG. Enter the bottom side of. As will be described later in detail, the retaining ring 12 is attached to the step portion between the end face 2b and the end face 9a, and the retaining ring 12 is attached to the outer container 2 to prevent the radiation shielded container 9 from falling out of the outer container 2. .

When the outer container 2 is cylindrical as in the present embodiment, the above-mentioned plate material 7 is press-fitted in order to prevent the radiation shield container 9 from rotating in the outer container 2 in the circumferential direction. Thus, the groove portion 10 having a width dimension slightly smaller than the distance between the two plate members 7 is formed in the bottom portion of the radiation shielding container 9. The groove 10 may not be formed if the outer container 2 is not cylindrical.

Further, on the end face 9a of the radiation shielding container 9,
When the radiation shield member 100 is housed in the radiation shielding container 9, the recess 11 into which the wing-shaped holding member 102 that is a part of the radiation shield member 100 is fitted is formed. The concave portion 11 has the same depth dimension as the plate thickness dimension of the wing-shaped holding member 102, and is in contact with the end surface 9a.
It has the same planar shape as the second part. Therefore, the radiation shield member 100 is fixed in position inside the radiation shielding container 9 by fitting the wing-shaped holding member 102 into the recess 11. By providing the concave portion 11 that functions as a position fixing portion in this way, the shielding container 9 and the radiation shield member 10 are provided.
Even if there is a slight gap between the radiation syringe member 100 and the shielding container 9, the radiation shield member 100 accidentally collides with the inner wall of the shielding container 9 and the blunt glass of the radiation shielding member 100 is determined. It is possible to prevent the product from being damaged and the syringe from cracking. As the position fixing portion of the wing-shaped holding member 102, the above-mentioned concave portion 11 is adopted in this embodiment, but it is not limited to the concave shape, and it is erected on the end surface 9a as shown in FIGS. It may be a protrusion 411 that can contact the outer peripheral surface of the wing-shaped holding member 102.

The holding ring 12 is an annular member having a through hole in the central portion as shown mainly in FIGS. 5 to 7, and is fitted to the inner peripheral surface of the outer container 2 as shown in FIG. And the holding ring 12 from the tubular portion 12b.

It has a limiting part 12c.
In addition, an annular protrusion 12d that engages with the retaining ring groove 6 formed on the inner peripheral surface of the outer container 2 is formed on the entire outer peripheral surface of the cylindrical portion 12b that contacts the inner peripheral surface of the outer container 2. To be done. In consideration of the case where the retaining ring 12 is removed from the outer container 2, the protrusion 12d preferably has a semicircular cross section as shown in the drawing. Such a retaining ring 12 has the tubular portion 12 b fitted to the inner peripheral surface of the outer container 2 and has the protrusion 1
By engaging 2d with the retaining ring groove 6, the outer container 2
Is attached to the opening of the. It should be noted that the protruding portion 12e protruding from the tubular portion 12b in the outer peripheral direction of the retaining ring 12 has an outer container 2
Abutting on the end surface 2b.

By attaching the retaining ring 12 to the outer container 2 in this way, the shield container drop-off preventing portion 12a comes into contact with the end surface 9a of the opening of the radiation shield container 9, and the radiation shield container 9 drops from the outer container 2. And the shield member drop-off limiting portion 12c is fitted in each recess 11 of the radiation shielding container 9 as shown in FIG.
Since it extends so as to cover and contact 02, the shield member drop-off limiting portion 12c prevents the radiation shield member 100 from easily falling off the radiation shield container 9. In the figure, the shield container drop-off prevention portion 12a and the shield member drop-off limiting portion 12c are described as having the same plate thickness, but in reality, the shield container drop-off prevention portion 12a has a plate thickness of 0.5 mm, for example.

m, and the plate thickness of the shield member drop-off limiting portion 12c is extremely thin.

The lid 3 is, as shown in FIGS. 1 and 11,
The cup shape is attached to the open end of the outer container 2 to close the open end of the outer container 2. On the inner peripheral surface of the top of the lid body 3, a projection 3a having a substantially semi-elliptical cross section is formed over the entire circumference. Further, inside the lid body 3, a cup-shaped radiation shielding member 13 made of a lead material and having a protrusion 13a engaging with the protrusion 3a provided on the outer peripheral surface is held. That is, the projection 3a of the lid 3 and the projection 13a of the radiation shielding member 13 are engaged with each other while the top surface 13b of the radiation shielding member 13 is in contact with the top inner surface 3b of the lid 3, and the radiation inside the lid 3 is reduced. Shielding member 13
Is retained. Further, in order to further facilitate the separation of the radiation shielding member 13 from the lid body 3, an appropriate gap 16 is provided between the outer peripheral surface 13d of the radiation shielding member 13 and the inner peripheral surface 3c of the lid body 3. . The gap 16 also serves to give the lid 3 flexibility, and facilitates opening and closing of the lid 3. The radiation shield member 13 and the lid body 3 are separated from each other by, for example, placing a thumb of one hand inside the radiation shield member 13 and putting an index finger on the outer side surface of the lid body 3 to separate the radiation shield member 13 and the lid body 3. The radiation shield member 13 can be easily removed from the lid body 3 by pinching the gap so as to eliminate the gap therebetween.

Further, the inner peripheral surface 3c near the opening end of the lid 3 has two sliding slopes 17a, 17a corresponding to the above-mentioned guide projection 8 formed on the outer peripheral surface of the outer container 2. An inverted chevron-shaped lid-side guide protrusion 17 is formed. Guide protrusion 8

Is moved to the outside in the axial direction of the outer container 2 to separate the outer container 2 and the lid 3.

Further, the height dimension H2 of the radiation shielding member 13 is such that when the annular groove 5 formed in the lid 3 and the annular ridge 4 formed in the outer container 2 are engaged with each other, the height of the radiation shielding member 13 is reduced. The opening end surface 13c of the member 13 abuts on the shield container drop-off prevention portion 12a and the shield member drop-off limiting portion 12c of the retaining ring 12. Therefore, the shield container drop-off prevention unit 1
The wing-shaped holding members 102, 102 of the radiation shield member 100 are completely fixed by the radiation shield member 13 and the radiation shield container 9 by the force pressing in the axial direction via the 2a and the shield member drop-off limiting portion 12c.

An annular cut portion 13e is formed on the entire outer peripheral surface of the lid 3 corresponding to the annular groove 5 in the lid 3.
The wall thickness of the lid body 3 sandwiched between the annular groove 5 and the annular cutout portion 13e is very thin as compared with other portions of the lid body 3. In the lid body 3, the opening side of the lid body 3 with respect to the annular cut portion 13e is the sealing connection portion 14. The seal connecting portion 14 employs the technique of the seal connecting portion disclosed in Japanese Utility Model Publication No. 05-024078 filed by the present applicant. That is, by pulling the knob portion 15 with respect to the lid body 3 and rotating the lid body 3 around the lid body 3, the seal connecting portion 14 and the lid body 3 are separated by the notch 13 e, and the lid body 3 and the outer container 2 are separated. The lid 3 can be detached from the outer container 2 by releasing the seal. Such a seal connecting portion 14 can avoid the risk that the lid 3 is loosened with respect to the outer container 2 or the lid 3 is accidentally opened and closed with respect to the outer container 2 during transportation. By pulling the knob portion 15 provided on the portion 14, the sealing of the lid body 3 and the outer container 2 is released by the annular cut portion 13e, the lid body 3 can be removed from the outer container 2, and the sealing is performed once. When the connection part 14 is released, it also means that the radioactive solution is used.

In the radiation-shielding-member transport container 1 according to the present embodiment having the above-described structure, the radiation-shielding member 100 containing the syringe is held in each recess 11 provided on the end face 9a of the radiation-shielding container 9 in a wing-like shape.
