An object of the present invention is to provide a syringe barrel container in which the outer peripheral surface of the syringe barrel is not easily damaged by a ring.

In order to achieve the above object, a syringe barrel container has a cylindrical barrel, a flange provided on the outer periphery of the barrel, and a cap attached to the tip of the barrel. A syringe barrel container for storing a plurality of syringes for filling a medicine provided with a contact portion on a side surface of the flange, the bottom of the syringe barrel being continuous with the bottom at the lower end and the periphery of the bottom toward the upper end. A container body having a peripheral wall portion that extends and a shelf provided on the peripheral wall portion; and the injection that is mounted on the shelf, is removably inserted into the syringe barrel, and locks the flange. A plurality of receiving tubes through which a tube can be suspended and suspended, and a nesting plate arranged at intervals, the receiving tube having a cylindrical shape with an upper end and a lower end opened, and the flange at the upper end A locking part that can be locked is formed, and its inner diameter is equal to the outer diameter of the body part. Is larger than the locking portion of the upper end of the receiving tube main body and protrudes to the upper end side from the portion other than the locking portion, and can contact the contact portion when the flange is locked to the locking portion. When the syringe barrel is suspended from the receiving tube, the protruding portion abuts against the contact portion, thereby restricting the rotation of the syringe barrel with respect to the receiving tube. Is.

The receiving tube has a recessed portion in which a part of the protruding portion is cut out from an inner peripheral edge to an outer peripheral edge of the receiving tube main body, and when the injection tube is suspended from the receiving tube, the recessed portion It is preferable that a part of the side surface of the flange is exposed.

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.

FIG. 1 and FIG. 2 show an example of a syringe barrel storage container 10 according to the present invention. FIG. 1 is a perspective view of the syringe barrel container 10, and FIG. 2 is a plan view of the 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, extends toward the upper end, an opening surrounded by the upper end of the peripheral wall, and a shelf 14 that is provided around the peripheral wall. Have The area of the bottom surface is narrower and narrower than the area of the opening surface of the opening. 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 whose upper ends and lower ends are opened through the nesting plate 16 and are arranged in a plurality of rows at intervals. When a plurality of receiving cylinders 18 are arranged without a gap, there is almost no gap between the flanges 30 of the injection cylinders 26 inserted into the adjacent receiving cylinders 18 as will be described later, and the flange 30 is hooked to perform injection. It becomes difficult to take out the tube 26. The

notches

15 and 15 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.

The receiving cylinder 18 shown in FIGS. 1 and 2 has a cylindrical hollow portion 27 of a cylindrical injection cylinder 26 in which the diameter of a hollow cylinder 18e (see FIG. 4A) of the receiving cylinder main body 18a is filled with a medicine. As shown in FIG. 3, the syringe barrel 26 is removably inserted. Here, for example, if the diameter of the hollow cylinder 18e is partially reduced so that the injection cylinder 26 inserted into the receiving cylinder 18 can be gripped, it becomes difficult to take out the injection cylinder 26 inserted into the receiving cylinder main body 18a. Further, when the syringe barrel 26 is taken out, the outer peripheral surface of the syringe barrel 26 may be easily damaged. As shown in FIG. 4A, the syringe barrel 26 is formed with a flange 30 having a contact portion on the outer peripheral portion of the proximal end of the body portion 27. The outer shape of the flange 30 viewed from the base end is a shape in which a part of a circular shape is cut out at two places, and each cut-out surface 30a is a contact portion. The two notch surfaces 30a are formed at positions facing each other across the base end opening at the base end of the body portion 27, particularly at positions facing each other across the center of the base end opening. The flange 30 may be formed between the distal end and the proximal end of the barrel portion 27 of the syringe barrel 26. In this case, the two notch surfaces 30a of the flange 30 are formed at positions facing each other with the body portion 27 interposed therebetween, particularly at positions facing each other with the center axis of the body portion 27 of the syringe barrel 26 interposed therebetween. The diameter of the arc portion of the flange 30 is the same as the outer diameter of the receiving tube main body 18a. The syringe barrel 26 is a left-right control.

The receiving tube 18 protrudes to the upper end side from a portion other than the engaging portion at the upper end of the receiving tube main body 18a, and a receiving portion that locks the flange 30 at the upper end. And a projecting portion capable of coming into contact with the cut-out surface 30a, which is a contact portion of the flange 30, when 30 is locked. The protruding portion may be formed so as to surround the entire periphery of the locking portion. However, like the receiving tube 18 shown in FIG. 3, a part of the protruding portion extends from the inner peripheral edge to the outer peripheral edge of the receiving tube main body 18a. It is preferable that a recess 18d is formed by cutting out the recess. In the receiving cylinder 18 shown in FIG. 3, a pair of recesses 18d are formed at positions facing each other across the cylindrical hollow 18e of the receiving cylinder main body 18a. As a result, the protrusions become a pair of protrusions 18b formed at positions facing each other across the hollow cylinder 18e of the receiving cylinder main body 18a. The flat bottom of the recess 18d extends from the inner periphery to the outer periphery of the receiving tube main body 18a, and constitutes a part of the locking portion that locks the flange 30. In addition, the inner wall surface of the recess 18 d is a step surface 18 c of the protruding portion 18 b located outside the locking portion of the flange 30. The step surface 18c is a contact surface that contacts the notch surface 30a of the flange 30 that is locked to the locking portion at the bottom of the recess 18d. The pair of protrusions 18b are formed at positions where the stepped surfaces 18c face each of the cutout surfaces 30a of the flange 30 locked by the locking portions via a narrow gap. The protruding length of the pair of protruding portions 18 b is equal to the thickness of the flange 30. Each projecting portion 18b is formed at the upper end of the receiving barrel body 18a in a left-right contrast, and the flange 30 of the syringe barrel 26 can be inserted without distinguishing between the left and right in combination with the left-right contrast. . In the present embodiment, the locking portion of the receiving tube main body 18a is composed of the bottom of the recess 18d, which is the upper end of the receiving tube main body 18a, and the step surface 18c of the protruding portion 18b and the upper end opening of the receiving tube main body 18a. However, the locking portion may be configured only from the bottom of the recess 18d. In this case, the stepped surface 18c of the protruding portion 18b is continuous with the inner wall of the receiving tube main body 18a, or the upper end of the receiving tube main body 18a between the stepped surface 18c of the protruding portion 18b and the upper end opening of the receiving tube main body 18a. However, it is depressed on the lower end side from the bottom of the recess 18d.

Since the receiving cylinder 18 shown in FIG. 3 has a recess 18d in which a part of the protruding portion is cut out from the inner peripheral edge to the outer peripheral edge of the receiving cylinder main body 18a, the injection cylinder 26 is inserted into the receiving cylinder 18 and received. When the flange 30 is locked to the locking portion of the cylinder body 18a, a part of the side surface of the flange 30 is exposed from between the pair of protruding portions 18b as shown in FIG. That is, when the syringe barrel 26 is inserted and the flange 30 is locked to the locking portion of the receiving tube main body 18a, a part of the side surface of the flange 30 is exposed by the recess 18d. By holding the exposed surface of the flange 30 and pulling out the syringe barrel 26, the syringe barrel 26 can be easily removed from the barrel 18.

A reduced diameter cylinder tip 29 is provided at the distal end of the body 27 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 is attached to the distal end portion of the cylindrical body portion 27 and protects the needle tube while preventing leakage of the medicine filled in the syringe barrel 26 from the needle tip. When the distal end portion of the body portion 27 is a so-called luer shape or cartridge shape without an injection needle, the distal end of the body portion 27 is formed by an elastic cap or a plastic cap with an elastic body packing inside. The drug outlet is sealed.

As shown in FIG. 4B, the flange 30 of the syringe barrel 26 is locked on the locking portion at the bottom of the concave portion 18d of the receiving barrel main body 18a. Each notch surface 30a, which is a contact portion of the locked flange 30, faces the stepped surface 18c of the projecting portion 18b facing each other through a narrow gap 34. The width of the gap 34 is such that at least a part of the notch surface 30a abuts on the stepped surface 18c, contacts the line, or contacts the surface due to vibration, inclination, or sudden movement of the syringe barrel container 10, and the syringe barrel 26 is excessive. It is narrow enough to prevent excessive rotation, swinging and lateral displacement. FIG. 4C shows a state in which a rotational stress is applied to the syringe barrel 26. In the syringe barrel 26 shown in FIG. 4C, rotational stress in the counterclockwise direction is applied due to vibration, inclination, and sudden movement during conveyance. The corner of each notch surface 30a that is the contact portion of the flange 30 linearly contacts the surface in the vicinity of the corner of the stepped surface 18c of the projecting portion 18b facing each other through the gap 34, and the syringe barrel 26 has an excessive amount. The rotation is blocked. Similarly, when rocking stress or lateral stress is applied to the syringe barrel 26, each notch surface 30a, which is a contact portion of the flange 30, is in contact with the stepped surface 18c of the projecting portion 18b facing the point contact / line contact or surface contact. Then, excessive swinging and lateral displacement of the syringe barrel 26 are prevented.

The syringe barrel storage container 10 shown in FIGS. 1 and 2 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 main body 12 to form the syringe barrel storage container 10, as shown in FIG. 3, each of the plurality of receiving tube main bodies 18 a of the nesting plate 16 has a reduced diameter cylinder tip. A syringe barrel 26 in which the needle tip of a needle tube fixed to 29 is sealed with a cap 28 is inserted. The syringe barrel container 10 is covered and sealed with a protective film 48 (see FIG. 9) or a protective lid made of resin (not shown), and autoclave sterilization, ethylene oxide gas sterilization, γ-ray sterilization. And sterilization such as 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.

Each notch surface that is a contact portion of the flange 30 of the syringe barrel 26 even when stress is exerted on the syringe barrel 26 inserted in the barrel main body 18a in the rotational direction, the swinging direction, or the lateral displacement direction during packing or transportation. 30a and the stepped surface 18c of the projecting portion 18b opposed thereto can abut against the excessive rotation, swinging, and lateral displacement of the syringe barrel 26. As a result, the syringe barrel 26 causes only minimal rotation, swinging, or lateral displacement within each gap 34, so that the outer peripheral surface of the syringe barrel 26 can be prevented from being damaged.

After the sterilized and sealed syringe barrel container 10 is transported to a factory that fills the syringe barrel with the medicine, the protective film or the lid covering the opening 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 tube body 18a of the nesting plate 16 is taken out from the syringe barrel 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 rubbing with the receiving barrel 18 as compared with the case of glass. For this reason, it is more important to prevent the syringe barrel 26 from excessively rotating due to the contact between each notch surface 30a that is a contact portion and the stepped surface 18c of the projecting portion 18b facing it. 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, and it is therefore more important to prevent excessive rotation of the syringe barrel 26.

The flange 30 of the syringe barrel 26 shown in FIGS. 3 and 4 only needs to be non-circular, and each cut-out surface 30a shown in FIG. 5A is slightly curved, and each flange 30 shown in FIG. It may be a polygonal shape whose corners are chamfered into a curved surface, an elliptical shape shown in FIG. 5C, or a regular polygonal shape (regular hexagonal shape) shown in FIG. In this case, if a portion other than the portion having the longest distance from the central axis of the barrel portion 27 of the syringe barrel 26 to the outer edge of the flange 30 when viewed from the base end side is included, the contact portion is the flange portion. It may be provided anywhere on the outer edge. That is, the shape shown in FIG. 5A includes a slightly curved cut surface 30a, and the shape shown in FIGS. 5B and 5D includes at least one side of a polygon. Thus, if it is an elliptical shape shown in FIG.5 (c), the contact part should just be provided so that parts other than the vertex on the long axis of an ellipse may be included. For example, when a rotational stress in the clockwise direction acts on the syringe barrel 26 having the elliptical flange 30 shown in FIG. 5C, each notch surface 30a is like a flange 30 'indicated by a one-dot chain line. The abutting surface 18c of the projecting portion 18b facing each other is linearly contacted to prevent the syringe barrel 26 from excessively rotating. In this way, even when packing or transporting, even if stress is applied to the syringe barrel 26 inserted into the receiving barrel body 18a in the rotational direction, the swinging direction, or the lateral displacement direction, the contact portion of the flange 30 faces it. The syringe barrel 26 can be prevented from excessive rotation, swinging and lateral displacement by contacting the stepped surface 18c of the protruding portion 18b. In addition, the contact part as used in the field of this invention refers not only to the part which actually contacts the level | step difference surface 18c of the protrusion part 18b, but the part which opposes the level | step difference surface 18c among the side surfaces of the flange 30.

Further, as shown in FIG. 6, a part of the flange 30 may protrude outward from the receiving tube body 18a. The flange 30 in FIG. 6 has a long shape, and part of the end portion on the long axis side is protruding

portions

30c and 30c. The protruding

portions

30 c and 30 c can be used for holding one or more syringe barrels 26 when the syringe barrel 26 is inserted into and removed from the barrel 18. In addition, the

protrusion part

30c, 30c may be one.

The protrusion length of each protrusion 18b shown in FIG. 4 is equal to the thickness of the flange 30. However, even if the protrusion length of each protrusion 18b is longer than the thickness of the flange 30, as shown in FIG. Good. Thus, if the protrusion length of each protrusion part 18b is lengthened, each step surface 18c protrudes rather than the flange 30 when the flange 30 is latched by the recessed part 18d of the cylinder main body 18a. For this reason, even when an upward stress is applied to the syringe barrel 26 during transport or the like, the flange 30 is difficult to exceed each stepped surface 18c and is difficult to come off from the recess 18d.

3, 4, and 7, the upper end of the receiving tube main body 18 a is a flat surface on which a locking portion is formed, but the upper end of the receiving tube main body 18 a may be provided with unevenness. As a result, a gap is formed between the upper end of the receiving tube main body 18 a and the front end surface of the flange 30. When the syringe barrel container 10 containing the syringe barrel 26 is subjected to autoclave sterilization or ethylene oxide gas sterilization, the gap is formed between the inner wall surface of the hollow cylinder 18e of the receiving barrel body 18a and the outer circumferential surface of the syringe barrel 26. The high-temperature and high-pressure steam and ethylene oxide gas flow in and out. In addition, the recessed part 18d of the receiving cylinder 18 may be depressed in the lower end side rather than a latching part, without comprising a part of latching part. In this case, a locking portion is formed between the stepped surface 18c of the protruding portion 18b and the upper end opening of the receiving tube main body 18a, and a gap is formed between the recessed portion 18d and the front end surface of the flange 30.

4, two protrusions 18b are formed on the upper end of the cylinder main body 18a so as to face each other, but only one protrusion 18b may be formed as shown in FIG. That is, the recess 18d is formed by cutting out a part of the protruding portion so that only one protruding portion 18d remains from the inner peripheral edge to the outer peripheral edge of the receiving tube main body 18a. In this case, when the upper end of the receiving tube body 18a is viewed from the side surface of the injection tube 26, the shape of the upper end is L-shaped. The step surface 18c of this one projecting portion 18b stands vertically to the outside of the locking portion of the flange 30. Moreover, the flange 30 has one notch surface 30a. The notch surface 30a of the flange 30 locked to the locking portion of the receiving tube main body 18a faces the stepped surface 18c of the protruding portion 18b via a narrow gap 34. The width of the gap 34 is such that a part of the notch surface 30a of the flange 30 and a part of the stepped surface 18c of the protruding portion 18b are applied even when stress in the rotational direction, swinging direction, or lateral displacement direction acts on the syringe barrel 26. It is narrow enough to abut and prevent excessive rotation, swinging, or lateral displacement of the syringe barrel 26. Even in this case, when the injection cylinder 26 is inserted and the flange 30 is locked to the locking portion of the receiving cylinder main body 18a, a part of the side surface of the flange 30 is exposed by the recess 18d. By holding the exposed surface of the flange 30 and pulling out the syringe barrel 26, the syringe barrel 26 can be easily removed from the barrel 18. The flange 30 may have two notch surfaces 30a.

In the present embodiment, the flange 30 locked to the upper end of the receiving tube main body 18a is partially exposed from the gap between the protrusions 18b formed on the receiving tube main body 18a. The side surface has a plurality of notched surfaces 30a (for example, six side surfaces 30a are formed on the side surface, and the hexagonal flange 30 as viewed from the upper surface side). All may be surrounded by the protrusion 18b. In this case, the syringe barrel 26 can be taken out from the barrel body 18 a by lifting the syringe barrel 26 from the barrel body 18 a by gripping the distal end side of the syringe barrel 26 and gripping the flange 30.

As shown in FIG. 3, the syringe barrel 26 inserted into the receiving barrel body 18a has a smaller diameter than the cylindrical hollow 18e of the receiving barrel body 18a as shown in FIG. It is easy to swing back and forth with respect to the paper surface. In order to further prevent the syringe barrel 26 from swinging in the front-rear direction, a positioning plate 42 for positioning the syringe barrel 26 is provided between the nesting plate 16 and the bottom surface of the container body 12 as shown in FIG. It is preferable to arrange. The positioning plate 42 is disposed between the bottom surface of the container main body 12 by a support base 44 protruding from the lower surface of the positioning plate 42 at a predetermined interval, and a plurality of positioning holes 42a into which the tip ends of the caps 28 are inserted. It has been drilled. It is preferable that the positioning hole 42a is opened to the bottom of the syringe barrel 26 so that the outer wall of the syringe barrel 26 does not contact the inner wall of the receiving barrel body 18a. If the outer wall of the syringe barrel 26 and the inner wall of the receiving tube main body 18a do not contact each other, there may be play between the cap 28 and the positioning hole 42a.

Further, as shown in FIG. 10B, a positioning member composed of a plurality of positioning cylinders 46 may be erected on the bottom surface of the container body 12 by inserting the tip of the cap 28 and positioning. The positioning cylinder 46 has a slit 46a in the vertical direction. When the cap 28 is inserted into the positioning cylinder 46, the air in the positioning cylinder 46 is pushed out of the positioning cylinder 46 through the slit 46a, and the cap 28 is positioned without being obstructed by the air in the positioning cylinder 46. It can be inserted into the tube 46. When the syringe barrel container 10 containing a plurality of syringe barrels 26 is autoclaved or ethylene oxide sterilized, it enters the space surrounded by the cap 28, the positioning barrel 46 and the bottom surface of the container body 12 through the slit 46a. Therefore, the space can be surely sterilized. When the slit 46a is formed from the upper end to the lower end of the positioning cylinder 46, the condensed water accumulated in the positioning cylinder 46 spreads over the entire bottom surface of the container body 12 through the slit 46a and is easily evaporated during autoclave sterilization. . The positioning tube 46 is preferably open directly below the syringe barrel 26 so that the outer wall of the syringe barrel 26 does not contact the inner wall of the receiving barrel body 18a. If the outer wall of the syringe barrel 26 and the inner wall of the receiving barrel body 18a are not in contact with each other, there may be play between the cap 28 and the positioning barrel 46. The axial direction of 46 may be shifted. Instead of the positioning cylinder 46, the positioning member may be a recess or protruding enclosure on the bottom surface. The positioning member may be at least three rib pieces that come into contact with the tip of the cap 28.
