When a plurality of syringe barrels are stored in a syringe barrel container for transport, etc., if the syringe barrel is swung due to vibration, inclination, or sudden movement, collision between the syringe barrel and the lower end of the inner wall of the receiver barrel may occur. By rubbing, the outer peripheral surface of the syringe barrel is damaged. Scratches and shavings are generated due to the scratches, and it may be difficult to maintain cleanliness by clinging to the syringe barrel due to static electricity, or the appearance may become dirty. Moreover, although it is an unused syringe barrel, it may be misidentified whether it is an old product which has been used or has expired.

The present invention has been made in order to solve the above-described problems, and even when a plurality of empty syringes for filling a medicine are suspended in a receiving container of a plate body in a storage container, It is an object of the present invention to provide a syringe barrel container in which the outer peripheral surface of the tube is hardly damaged.

The syringe barrel storage container made to achieve the above object is a syringe barrel storage container for storing a plurality of drug filling syringes having a cap at the distal end and a flange at the proximal end, A container main body having a bottom at the lower end, a peripheral wall portion extending around the bottom and extending toward the upper end, an opening surrounded by the upper end of the peripheral wall portion, and a shelf provided on the peripheral wall portion, A plurality of cylindrical receiving tubes, which are placed on the shelf, can be removably inserted into the syringe barrel, and can be suspended and suspended by locking the flange, are arranged through. And a plurality of enclosures into which the cap is inserted when the syringe barrel is suspended from the receptacle tube, and is provided at a position facing each of the plurality of receptacle tubes at the bottom. Space and volume surrounded by the cap, the enclosure and the bottom A communication passage communicating with the space outside the enclosure in the body, and the syringe barrel suspended from the receptacle is inclined with respect to the axis of the receptacle so that the cap and the enclosure are in contact with each other. When contacted, the syringe barrel and the lower end of the inner wall of the receiving barrel do not come into contact with each other.

The enclosure has a cylindrical shape protruding from the bottom toward the upper end side, and when the cap is inserted into the enclosure, there is a slit extending from the upper end of the enclosure to at least the lower end side of the end of the cap. At least one may be formed in the enclosure, and the slit may function as the communication path.

The slit is preferably formed from the upper end to the lower end of the enclosure.

The enclosure may include at least three ribs protruding from the bottom toward the upper end, and a gap between adjacent ribs may function as the communication path.

The upper end of the enclosure is provided with a guide portion that has an inclined surface in which the distance from the central axis of the receiving cylinder facing the enclosure gradually increases toward the upper end, and guides the cap into the enclosure. It is preferable.

It is preferable that the container main body is sealed by inserting the syringe barrel into each of the receptacles and covering the opening with a protective film or a protective lid.

The syringe barrel is preferably made of plastic, particularly preferably a cyclic olefin homopolymer or a cyclic olefin copolymer.

Hereinafter, modes for carrying out the present invention will be described in detail, but the scope of the present invention is not limited to these modes.

<First Embodiment>
A first embodiment of the syringe barrel container according to the present invention is shown in FIG. FIG. 1 is a perspective view of a syringe barrel container 10. The syringe barrel storage container 10 includes a box-shaped container body 12 having an open upper surface and a nesting plate 16 having an outer dimension smaller than the inner dimension of the opening. The container main body 12 has a bottom at the lower end, a peripheral wall that extends around the bottom and extends toward the upper end, an opening 19 surrounded by the upper end of the peripheral wall, and a shelf 14 provided around the peripheral wall. And have. The area of the bottom surface is narrower and narrower than the area of the opening surface of the opening 19. The syringe barrel container 10 has a nesting plate 16 mounted on a shelf 14 of a container body 12. A plurality of cylindrical receiving cylinders 18 are arranged in the nest plate 16 so as to penetrate therethrough. The two notches 15 provided at the edge of the nesting plate 16 are used to hold the nesting plate 16 by hooking them with fingers or hooks when the nesting plate 16 is inserted into and removed from the container body 12.

1 is inserted into the cylindrical receiving cylinder 18 shown in FIG. 1 so as to be detachable as shown in FIG. The barrel of the syringe cylinder 26 has a smaller diameter than the hollow cylinder of the receiving cylinder 18. The proximal end portion of the syringe barrel 26 has an opened proximal end opening, and a flange 30 is provided on the outer periphery of the proximal end opening. The flange 30 is locked to the upper end of the receiving tube 18. Thereby, the syringe barrel 26 is suspended from the receiving barrel 18. The flange 30 may be provided at the proximal end portion of the syringe barrel 26 on the distal end side with respect to the proximal end opening portion of the syringe barrel 26.

A reduced diameter cylinder tip 29 is provided at the tip of the injection cylinder 26, and a needle tube as an injection needle is fixed. The needle tube is covered with a cap 28 made of an elastic material such as isoprene rubber, and the needle tip of the needle tube is sealed with the cap 28. The cap 28 protects the needle tube while preventing leakage of the medicine filled in the syringe barrel 26 from the needle tip. When the tip of the syringe barrel 26 has a so-called luer shape or cartridge shape without an injection needle, an elastic cap or a plastic cap with an elastic packing inside is attached to the tip of the syringe barrel 26. The drug outlet is sealed.

The syringe barrel 26 with the flange 30 locked to the upper end of the receptacle 18 is inserted into the enclosure 17 of the bottom portion 12a of the container body 12 by inserting the cap 28 at the tip thereof into the lower end of the inner wall of the receptacle 18. It is positioned at a predetermined position without contact. The enclosure 17 is provided on the bottom portion 12a of the container body 12 so as to face each of the plurality of receiving cylinders 18, and has a cylindrical shape protruding from the bottom portion 12a toward the upper end side. At least one slit 17c is formed from the lower end to the lower end. The inner diameter of the enclosure 17 is slightly larger than the outer diameter of the cap 28 so that the cap 28 can be inserted into the enclosure 17. As shown in FIG. 3, the syringe barrel 26 in which the distal end portion of the cap 28 is inserted into the enclosure 17 is a predetermined position in the syringe barrel container 10, that is, the syringe barrel 26 suspended and suspended from the receptacle barrel 18. When the cap 28 and the enclosure 17 are inclining with respect to the 18 axis, the syringe barrel 26 and the lower end portion of the inner wall of the receiving barrel 18 are positioned so as not to abut. For this reason, even if stress in the swinging direction acts on the syringe barrel 26, the syringe barrel 26 hardly swings, and contact between the syringe barrel 26 and the lower end portion of the inner wall of the receiving barrel 18 can be prevented. Thereby, it can prevent that the outer peripheral surface of the injection cylinder 26 inclined with respect to the axis | shaft of the receiving cylinder 18 collides and / or scratches with the lower end part of the inner wall of the receiving cylinder 18 and is damaged. Note that a plurality of slits 17c may be formed around the central axis of the receiving cylinder 18, for example, three at regular intervals.

On the other hand, when the enclosure 17 is not provided on the bottom surface of the bottom 12a of the container body 12 so as to face the receiving cylinder 18, the syringe cylinder 26 is likely to swing around the flange 30 as a fulcrum. The syringe barrel 26 tilted with respect to the axis of the receiving barrel 18 due to swinging may be damaged by collision and / or rubbing with the lower end portion of the inner wall of the receiving barrel 18.

The slit 17 c formed in the enclosure 17 functions as a communication path that communicates the space surrounded by the cap 28, the enclosure 17, and the bottom 12 a and the space outside the enclosure 17 in the container body 12. When the cap 28 is inserted into the enclosure 17, the air in the enclosure 17 is pushed out of the enclosure 17 through the slit 17 c that is a communication path. For this reason, it is possible to prevent the cap 28 from being difficult to insert into the enclosure 17 due to the air in the enclosure 17. Further, as will be described later, when the syringe barrel container 10 containing a plurality of syringe barrels 26 is autoclaved or ethylene oxide sterilized, the sterilized gas passes through the slit 17c, which is a communication path, through the cap 28, the enclosure 17, and the bottom 12a. Since it can penetrate into the space surrounded by, the space can be sterilized reliably. In the case of autoclave sterilization, the condensed water accumulated in the enclosure 17 easily evaporates through the slit 17c, which is a communication path. In the case of ethylene oxide gas sterilization, the cap 28, the enclosure 17 and the bottom 12a are surrounded by the sterilization. The ethylene oxide gas remaining in the space can easily escape to the outside through the slit 17c which is a communication path. Further, since the slit 17c is formed from the upper end to the lower end of the enclosure 17, in the case of autoclave sterilization, the condensed water accumulated in the enclosure 17 passes through the slit 17c and spreads over the entire bottom portion 12a of the container body 12 and easily evaporates. .

Further, a tapered surface 17e is formed at the upper end portion of the enclosure 17 as shown in FIGS. The tapered surface 17 e is an inclined surface in which the distance from the central axis of the receiving cylinder 18 facing the enclosure 17 gradually increases toward the upper end side, and is a guide portion that guides the cap 28 into the enclosure 17. Thereby, the cap 28 can be reliably inserted into the enclosure 17.

The syringe barrel storage container 10 shown in FIG. 1 is manufactured and used as follows. After the nesting plate 16 is placed on the shelf 14 on the inner wall surface of the container body 12 to form the syringe barrel container 10, as shown in FIG. The syringe barrel 26 in which the needle tip of the needle tube fixed to the diameter tube tip 29 is sealed is inserted. At this time, the cap 28 can be inserted into the enclosure 17 without being obstructed by the air in the enclosure 17 by the slit 17c functioning as a communication path. Thereafter, the syringe barrel container 10 is covered and sealed with a protective film 48 (see FIG. 3) or a protective lid made of resin (not shown), and the autoclave sterilization, ethylene oxide gas sterilization, It is subjected to either γ-ray sterilization or electron beam sterilization. The sterilized syringe barrel container 10 is packed in a sealed state with a protective film or a protective lid made of resin, and is supplied for transportation.

The syringe barrel 26 with the flange 30 locked to the upper end of the receiving barrel 18 is positioned at a predetermined position in the syringe barrel container 10 by inserting the cap 28 into the enclosure 17 of the bottom 12a of the container body 12. Yes. As a result, even when stress is applied to the syringe barrel 26 inserted into the receiving barrel 18 in the swinging direction during packing or transportation, the syringe barrel 26 hardly swings, and the syringe barrel 26 and the inner wall of the receiving barrel 18 It is possible to prevent contact with the lower end of the syringe barrel 18, and to prevent the outer peripheral surface of the syringe barrel 26 from being damaged by collision with the lower end of the inner wall of the receiving barrel 18 or scratching.

After the sterilized and sealed syringe barrel container 10 is transported to the factory for filling the syringe barrel 26 with the medicine, the protective film or the lid covering the opening 19 of the container body 12 is removed in the clean room. When filling the syringe 26 with a medicine, for example, the syringe barrel container 10 containing the syringe barrel 26 is placed at a predetermined position of a medicine filling device (not shown), The syringe 26 is filled with a predetermined amount of a desired medicine from the nozzle. Next, after the syringe barrel 26 locked to the upper end of the receiving barrel 18 of the nesting plate 16 is taken out from the syringe barrel storage container 10, a pusher is inserted to obtain a prefilled syringe. The prefilled syringe is sterilized as necessary, individually inserted and sealed in a packaging bag, transported to a medical site, and provided to a user such as a doctor.

As the material of the nesting plate 16 including the container body 12 and the receiving cylinder 18, plastic, for example, polyolefin resin such as polyethylene, polypropylene, and cyclic polyolefin; polystyrene; polycarbonate; polyester such as polyethylene terephthalate; polyamide can be used. In particular, when sterilization is performed by an autoclave, it is preferable to use polypropylene, polycarbonate, or the like, which is a plastic having high heat resistance, as the material of the nesting plate 16 including the container body 12 and the receiving cylinder 18.

Also, as the material of the syringe barrel 26, plastic as described above can be used in addition to glass. As the plastic used for the syringe barrel 26, a cyclic olefin homopolymer or a cyclic olefin copolymer is used which is transparent so that the chemical liquid filled therein can be visually confirmed from the outside and has little interaction with the chemical liquid. It is preferable. Here, when the syringe barrel 26 is made of plastic, the outer peripheral surface of the syringe barrel 26 is likely to be damaged due to a collision with the lower end portion of the inner wall of the receiving barrel 18 and / or rubbing, as compared with a case of glass. For this reason, it is more important to prevent the cap 28 inserted in the enclosure 17 from abutting the syringe barrel 26 with the flange 30 locked to the upper end of the barrel 18 and the lower end portion of the inner wall of the barrel 18. Become. In particular, when the material of the syringe barrel 26 is a cyclic olefin homopolymer or a cyclic olefin copolymer, scratches on the outer peripheral surface of the syringe barrel 26 are conspicuous, thereby preventing contact between the syringe barrel 26 and the lower end portion of the inner wall of the receiving barrel 18. It becomes even more important.

When the syringe barrel container 10 containing a plurality of syringe barrels 26 is autoclaved or ethylene oxide gas sterilized, the protective film 48 is sterilized paper or resin having water vapor or ethylene oxide gas permeability and fine particle impermeability. A non-woven fabric made of resin or a resin sheet provided with a sterilized paper and a non-woven fabric made of resin is used. The fine particles mentioned here refer to bacteria, bacteria, and the like. In addition, when the syringe barrel container 10 containing a plurality of syringe barrels 26 is γ-ray sterilized or electron beam sterilized, a resin film can be used as the protective film 48 in addition to sterilized paper and resin nonwoven fabric. Further, the protective film 48 may be a bag-like one that covers the entire syringe barrel storage container 10. In addition, as a thing which covers the opening part 19 of the container main body 12, resin-made protective lids (not shown) may be sufficient.

The syringe barrel storage container 10 of the present embodiment has been described above. In the present embodiment, the enclosure 17 has a cylindrical shape. However, the enclosure is not limited thereto, and the enclosure may be a polygonal cylinder into which the cap 28 can be inserted. In the present embodiment, the slit 17c that functions as the communication path is formed from the upper end to the lower end of the enclosure 17, but the slit 17c that functions as the communication path is a cap inserted at least from the upper end of the enclosure. What is necessary is just to be formed so that it may extend from the front-end | tip of 28 to the lower end side. As a result, when the cap 28 is inserted into the enclosure, the air in the enclosure is pushed out of the enclosure through the slit 17c, which is a communication path, so that the cap 28 can be enclosed without being obstructed by the air in the enclosure. Can be inserted. Further, when the syringe barrel container 10 containing a plurality of syringe barrels 26 is autoclaved or ethylene oxide sterilized, it can enter the space surrounded by the cap 28, the enclosure and the bottom portion 12a through the slit 17c which is a communication path. Therefore, the space can be reliably sterilized. In this embodiment, one slit 17c functioning as a communication path is formed. However, a plurality of slits 17c may be formed, and the interval between them is equal around the central axis of the enclosure 17. There may also be unequal intervals.

Second Embodiment
FIG. 4 shows a second embodiment of the syringe barrel container according to the present invention. FIG. 4 is a cross-sectional view of the second embodiment in a state where the syringe barrel 26 is housed. Hereinafter, although the syringe barrel storage container 10 of the present embodiment will be described, differences from the syringe barrel storage container 10 of the first embodiment will be mainly described, and description of similar matters will be omitted. The syringe barrel storage container 10 of the present embodiment is the same as the syringe barrel storage container 10 of the first embodiment except that the shape of the enclosure 17 is different.

As shown in FIG. 4, the syringe barrel storage container 10 of the present embodiment is provided on the bottom 12a of the container body 12 so as to face each of the plurality of receiving cylinders 18, and from the bottom 12a toward the upper end side. It has a protruding cylindrical enclosure 17. Unlike the enclosure 17 of the first embodiment, the enclosure 17 is not formed with a slit 17 c, but its inner diameter is sufficiently larger than the outer diameter of the cap 28 of the syringe barrel 26. For this reason, the distal end portion of the cap 28 of the injection cylinder 26 inserted into the receiving cylinder 18 can be reliably inserted into the enclosure 17. Further, the difference between the inner diameter of the enclosure 17 and the outer diameter of the cap 28 is smaller than the difference between the inner diameter of the receiving cylinder 18 and the outer diameter of the injection cylinder 26. Therefore, even if the syringe barrel 26 suspended from the receptacle 18 is inclined in the direction of the arrow G shown by the two-dot chain line in FIG. The cap 28 and the enclosure 17 abut before the lower end of the inner wall 18 abuts. That is, when the syringe barrel 26 suspended from the receptacle 18 is tilted with respect to the axis of the receptacle 18 and the cap 28 and the enclosure 17 come into contact with each other, the syringe 26 and the lower end portion of the inner wall of the receptacle 18 Does not come into contact. Further, even when the syringe barrel 26 slides in the direction of the arrow H indicated by the two-dot chain line in FIG. 4 and the slide syringe barrel 26 ″ contacts the inner wall surface of the receiving barrel 18, the cap 28 is also attached to the inner wall surface of the enclosure 17. In this state, the syringe barrel 26 ″ is not inclined in the direction of the arrow I shown by the two-dot chain line in FIG. As described above, when the difference between the inner diameter of the enclosure 17 and the outer diameter of the cap 28 is equal to or smaller than the difference between the inner diameter of the receiving cylinder 18 and the outer diameter of the injection cylinder 26, the inclination is made with respect to the axis of the receiving cylinder 18. The syringe barrel 26 and the lower end portion of the inner wall of the receiving barrel 18 do not come into contact with each other. Thereby, it can prevent that the outer peripheral surface of the injection cylinder 26 inclined with respect to the axis | shaft of the receiving cylinder 18 collides and / or scratches with the lower end part of the inner wall of the receiving cylinder 18 and is damaged.

Since the inner diameter of the enclosure 17 is sufficiently larger than the outer diameter of the cap 28, a gap 17 d is formed between the enclosure 17 and the cap 28. The gap 17d functions as a communication path that communicates the space surrounded by the cap 28, the enclosure 17, and the bottom 12a with the space outside the enclosure 17 in the container body 12. When the cap 28 is inserted into the enclosure 17, the air in the enclosure 17 is pushed out of the enclosure 17 through the gap 17 d that is a communication path. For this reason, it is possible to prevent the cap 28 from being difficult to insert into the enclosure 17 due to the air in the enclosure 17. Further, when the syringe barrel container 10 containing a plurality of syringe barrels 26 is autoclave sterilized or ethylene oxide sterilized, the sterilization gas is surrounded by the cap 28, the enclosure 17 and the bottom portion 12a through the gap 17d which is a communication path. Since it can penetrate into the space, the space can be surely sterilized. In the case of autoclave sterilization, the condensed water accumulated in the enclosure 17 easily evaporates through the gap 17d which is a communication path. In the case of ethylene oxide gas sterilization, the cap 28, the enclosure 17 and the bottom 12a are surrounded by the sterilization. The ethylene oxide gas remaining in the space can easily escape to the outside through the gap 17d which is a communication path.

Further, a tapered surface 17e is formed at the upper end of the enclosure 17 as shown in FIG. The tapered surface 17 e is an inclined surface in which the distance from the central axis of the receiving cylinder 18 facing the enclosure 17 gradually increases toward the upper end side, and is a guide portion that guides the cap 28 into the enclosure 17. Thereby, the cap 28 can be reliably inserted into the enclosure 17.

The syringe barrel storage container 10 of the present embodiment has been described above. In the present embodiment, the enclosure 17 has a cylindrical shape. However, as in the first embodiment, the enclosure may have a polygonal cylindrical shape into which the cap 28 can be inserted. Moreover, you may provide the slit 17c which functions as a communicating path similar to 1st Embodiment in the enclosure 17. FIG. Thus, when the cap 28 is inserted into the enclosure 17, the air in the enclosure 17 is pushed out of the enclosure 17 through the slit 17c as well as the gap 17d, and is not obstructed by the air in the enclosure 17. The cap 28 can be inserted into the enclosure 17 more reliably. Further, when the syringe barrel container 10 containing a plurality of syringe barrels 26 is autoclave sterilized or ethylene oxide sterilized, the sterilizing gas is surrounded not only by the gap 17d but also by the cap 28 and the bottom 12a through the slit 17c. Since it can penetrate into the space, the space can be sterilized more reliably. In the case of autoclave sterilization, the condensed water accumulated in the enclosure 17 evaporates not only through the gap 17d but also through the slit 17c, so that it is easier to evaporate. In the case of ethylene oxide gas sterilization, the cap 28 and the enclosure 17 Since the ethylene oxide gas remaining in the space surrounded by the bottom portion 12a escapes not only through the gap 17d but also through the slit 17c, it is easier to escape to the outside.

<Third Embodiment>
A third embodiment of the syringe barrel container 10 according to the present invention is shown in FIGS. FIG. 5 is a cross-sectional view of the third embodiment in a state where the syringe barrel 26 is housed. 6 and 7 are cross-sectional views of a modification of the third embodiment in a state where the syringe barrel 26 is housed. FIG. 8 is a perspective view (a) and a cross-sectional view (b) of the enclosure 17 in a modification according to the third embodiment. Hereinafter, although the syringe barrel storage container 10 of the present embodiment will be described, differences from the syringe barrel storage container 10 of the first embodiment will be mainly described, and description of similar matters will be omitted. The syringe barrel storage container 10 of the present embodiment is the same as the syringe barrel storage container 10 of the first embodiment except that the shape of the enclosure 17 is different.

As shown in FIG. 5, the syringe barrel storage container 10 of the present embodiment is provided on the bottom 12a of the container body 12 so as to face each of the receiving cylinders 18 and protrudes from the bottom 12a toward the upper end side. A cylindrical enclosure 17 is provided, and each enclosure 17 is formed with at least one slit 17c from its upper end to its lower end. The inner diameter of the enclosure 17 is sufficiently larger than the outer diameter of the cap 28 of the syringe barrel 26. For this reason, a gap 17 d is formed between the enclosure 17 and the cap 28, and the distal end portion of the cap 28 of the injection cylinder 26 inserted into the receiving cylinder 18 can be reliably inserted into the enclosure 17. However, the inner diameter of the enclosure 17 is such that the injection cylinder 26 comes into contact with the lower end portion of the inner wall of the receiving cylinder 18 when the injection cylinder 26 is inclined with respect to the axis of the receiving cylinder 18 and the cap 28 contacts the enclosure 17. It is necessary to be within the range where Specifically, it is necessary to satisfy Equation 1 below. As shown by the two-dot chain line in FIG. 5, when the syringe barrel 26 is tilted to the maximum with respect to the axis of the receiving barrel 18 to an inclination angle α, the formula 1 is injected into the lower end portion of the inner wall of the receiving barrel 18. It is determined on the assumption that the cap 26 is in contact with the enclosure 17 at the same time as the tube 26 contacts. When the syringe barrel 26 swings the most and the syringe barrel 26 collides with the lower end portion of the inner wall of the receiving barrel 18, the possibility of damage to the outer peripheral surface of the syringe barrel 26 is greatest. When the inner diameter of the enclosure 17 satisfies Equation 1, the cap 28 and the enclosure 17 come into contact with each other when the syringe barrel 26 swings the most, and the syringe barrel 26 collides with the lower end portion of the inner wall of the receiving barrel 18. Can be prevented. Thereby, the outer peripheral surface of the syringe barrel 26 can be hardly damaged. In Formula 1, A: outer diameter of the injection cylinder 26, B: inner diameter of the receiving cylinder 18, C: height of the receiving cylinder 18, D: outer diameter of the portion that contacts the enclosure 17 of the cap 28, E: of the enclosure 17 Inner diameter, F: The length from the tip of the receiving tube 18 to the point of contact with the enclosure 17 of the cap 28.

When the syringe barrel 26 is tilted from the maximum tilted position with respect to the axis of the receiving barrel 18 to the opposite side where the central axis of the receiving barrel 18 is the target point, the receiving barrel 18 The hung syringe barrel 26 swings most greatly. When the syringe barrel 26 swings the most and the syringe barrel 26 collides with the lower end portion of the inner wall of the receiving barrel 18, the possibility of damage to the outer peripheral surface of the syringe barrel 26 is greatest. When the inner diameter of the enclosure 17 satisfies the above Equation 1, when the syringe barrel 26 swings the most, the cap 28 and the inner wall of the enclosure 17 come into contact with each other, and the lower end portion of the inner wall of the syringe barrel 26 and the receiving barrel 18 And can prevent collisions. Thereby, the outer peripheral surface of the syringe barrel 26 can be hardly damaged.

The slit 17c formed in the enclosure 17 and the gap 17d between the enclosure 17 and the cap 28 are a space surrounded by the cap 28, the enclosure 17 and the bottom 12a, and a space outside the enclosure 17 in the container body 12. It functions as a communication path that communicates. When the cap 28 is inserted into the enclosure 17, the air in the enclosure 17 is pushed out of the enclosure 17 through the slit 17 c and the gap 17 d which are communication paths. For this reason, it is possible to prevent the cap 28 from being difficult to insert into the enclosure 17 due to the air in the enclosure 17. Further, when the syringe barrel container 10 containing a plurality of syringe barrels 26 is autoclaved or ethylene oxide sterilized, the sterilizing gas passes through the slit 17c and the gap 17d, which are communication paths, into the cap 28, the enclosure 17, and the bottom portion 12a. Since it can penetrate into the enclosed space, the space can be sterilized reliably. In the case of autoclave sterilization, the condensed water accumulated in the enclosure 17 is likely to evaporate through the slit 17c and the gap 17d which are communication paths. In the case of ethylene oxide gas sterilization, the cap 28, the enclosure 17 and the bottom 12a are sterilized after sterilization. The ethylene oxide gas remaining in the enclosed space can easily escape to the outside through the slit 17c and the gap 17d which are communication paths. Further, since the slit 17c is formed from the upper end to the lower end of the enclosure 17, in the case of autoclave sterilization, the condensed water accumulated in the enclosure 17 passes through the slit 17c and spreads over the entire bottom portion 12a of the container body 12 and easily evaporates. .

Further, the nesting plate 16 may be a nesting plate 16 whose outer shape is smaller than the outer shape of the shelf 14 of the container body 12 as in the modification of the present embodiment shown in FIG. Thereby, it becomes easy to take in and out the nesting plate 16 placed on the shelf 14 of the container body 12 from the opening 19 of the container body 12. In this case, the syringe barrel container 10 is preferably provided with positioning means for preventing lateral displacement of the nesting plate 16 placed on the shelf 14. For example, as shown in FIG. 6, the positioning means is provided in a substantially rectangular nesting plate 16, two positioning holes 16 a provided on the diagonal line, and a shelf 14 so as to be fitted in each positioning hole. It consists of two protrusions 14a (in FIG. 6, one of the two positioning holes 16a is omitted and one of the two protrusions 14a is omitted). Since each protrusion is fitted in each positioning hole, the nesting plate 16 placed on the shelf 14 does not move sideways, and the positional deviation between the receiving cylinder 18 and the enclosure 17 facing each other can be prevented. Thereby, it is possible to prevent the syringe barrel 26 and the lower end portion of the inner wall of the receptacle tube 18 from coming into contact with each other due to the positional deviation between the receptacle tube 18 and the enclosure 17 facing each other. The protrusion 14a may protrude from the nesting plate 16 and the positioning hole 16a may be opened as a recess that does not penetrate the shelf 14.

Further, the positioning means may be a rib 12b formed on the peripheral wall portion of the container main body 12 from the shelf 14 toward the upper end as in a modification of the present embodiment shown in FIG. At least one rib 12b is provided on each of the four peripheral wall portions of the container body 12, and each rib 12b is opposed to each side surface of the substantially rectangular nested plate 16 placed on the shelf 14, The nesting plate 16 placed on the shelf 14 does not move sideways, and it is possible to prevent positional deviation between the receiving cylinder 18 and the enclosure 17 facing each other. Thereby, it is possible to prevent the syringe barrel 26 and the lower end portion of the inner wall of the receptacle tube 18 from coming into contact with each other due to the positional deviation between the receptacle tube 18 and the enclosure 17 facing each other.

Further, as shown in FIG. 8 (a), the enclosure 17 has rib pieces 17a made of a plurality of rectangular plates as shown in FIG. It may be arranged in a ring shape at a predetermined interval. In the present embodiment, four rib pieces 17a are arranged. The rib piece 17 a shown in FIG. 8A is disposed so that the surface in the thickness direction (thick side surface) faces the inside of the enclosure 17, and the thick side surface is a surface that contacts the cap 28. In this case, the inner diameter (E) of the enclosure 17 in Equation 1 is the same as that of the opposite receiving cylinder 18 when the cap 28 is in contact with both of the two adjacent rib pieces 17a (see the one-dot chain line in FIG. 8B). This is the diameter of a virtual circle (see the broken line in FIG. 8B) whose radius is the distance from the central axis to the outer peripheral surface of the cap 28 that is furthest away. When the inner diameter of the enclosure 17 satisfies Equation 1, the cap 28 and the enclosure 17 come into contact with each other when the syringe barrel 26 swings the most, and the syringe barrel 26 collides with the lower end portion of the inner wall of the receiving barrel 18. Can be prevented. Thereby, the outer peripheral surface of the syringe barrel 26 can be hardly damaged. Further, as shown in FIG. 8A, an inclined surface (tapered surface 17e) in which the distance from the central axis of the opposite receiving cylinder 18 gradually increases toward the upper end side at the upper end portion of the thick side surface of the rib piece 17a. Is formed. The tapered surface 17 e is a guide portion that guides the cap 28 into the enclosure 17, and the cap 28 can be reliably inserted into the enclosure 17 by the guide portion.

As mentioned above, although the syringe barrel container of the present invention has been described with respect to the illustrated embodiment, the present invention is not limited to this, and an arbitrary component may be added. Further, the syringe barrel container of the present invention may be a combination of any two or more configurations (features) of the above embodiments. For example, you may comprise the enclosure 17 of 1st Embodiment and 2nd Embodiment from the some rib piece 17a described in FIG. 8 of 3rd Embodiment. Moreover, you may change the nesting board 16 of 1st Embodiment and 2nd Embodiment into the nesting board 16 described in 3rd Embodiment. In this case, as in the third embodiment, it is preferable that the syringe barrel storage container is provided with positioning means for preventing the lateral displacement of the nesting plate 16 placed on the shelf 14. The enclosure may be a depression formed in the bottom 12a of the container body 12.
