Description

本発明は、吊下用部材を備えた医療用液体収納用容器体およびそれを用いた薬剤充填済み医療用容器に関する。 The present invention relates to a medical liquid storage container body provided with a hanging member and a drug-filled medical container using the same.

吊り下げ用の吊り具が上部に取り付けられた医療用容器が、いくつか提案されている。例えば、特許３５９４２８０号公報（特許文献１）に「吊具付容器の製造方法」が開示されている。
特許文献１の吊具付容器は、容器本体（１）と吊り具（２）を備える。容器本体は、底面（１５）の外周側には、リブとして機能する折返し部（１５Ｃ）が設けられている。吊り具（２）は、図４に示す様に、底面（１５）の凹没部分にほぼ嵌合する形状になされている。具体的には、吊り具（２）は、外郭を略矩形の平面形状になされた帯状の枠部（２１）と、枠部（２１）の１組の対角を連結する帯状の連結部（２２）と、連結部（２２）の中央（枠部（２１）の中心）に位置し且つ円盤状になされた固定部（２３）とから構成される。 Several medical containers have been proposed with a hanging device attached to the top. For example, Japanese Patent No. 3594280 (Patent Document 1) discloses "a method for manufacturing a container with a hanging tool".
The container with a hanger of Patent Document 1 includes a container body (1) and a hanger (2). The container body is provided with a folded portion (15C) that functions as a rib on the outer peripheral side of the bottom surface (15). As shown in FIG. 4, the hanger (2) has a shape that substantially fits into the recessed portion of the bottom surface (15). Specifically, the hanger (2) has a strip-shaped connecting portion (21) having a substantially rectangular planar shape and a strip-shaped connecting portion (21) connecting a pair of diagonals of the frame portion (21). 22) and a fixed portion (23) located at the center of the connecting portion (22) (center of the frame portion (21)) and formed in a disk shape.

吊り具（２）の連結部（２２）の基端部分であって、容器本体（１）の底面（１５）に対峙する枠部（２１）の表面には、連結部（２２）の側縁に沿って枠部（２１）を対称に折り曲げるための各一対の溝（２１ｅ）が設けられる。斯かる溝（２１ｅ）を利用し、枠部（２１）の隣接する２辺を１組として各組ごとに三角形状に折り曲げられることにより、吊り具（２）は、容器本体（１）の底面（１５）から突出する吊り下げ手段として機能する。すなわち、図３及び図４に示す容器を吊り下げる場合は、容器本体（１）の底面（１５）に取り付けられた吊り具（２）の枠部（２１）を折り曲げることにより、底面（１５）から突出する略三角形状の１組のベルトを形成する。従って、図６に示す様に、折り曲げた吊り具（２）をフック等に掛止することにより、容器本体（１１）を転倒状態で吊り下げることができるものとなっている。 The side edge of the connecting portion (22) is on the surface of the frame portion (21) which is the base end portion of the connecting portion (22) of the hanging tool (2) and faces the bottom surface (15) of the container body (1). Each pair of grooves (21e) for symmetrically bending the frame portion (21) is provided along the above. By using such a groove (21e) and bending each group into a triangular shape with two adjacent sides of the frame portion (21) as one set, the hanger (2) can be formed on the bottom surface of the container body (1). It functions as a hanging means protruding from (15). That is, when suspending the container shown in FIGS. 3 and 4, the bottom surface (15) is formed by bending the frame portion (21) of the suspending tool (2) attached to the bottom surface (15) of the container body (1). A set of substantially triangular belts protruding from the belt is formed. Therefore, as shown in FIG. 6, the container body (11) can be hung in an overturned state by hooking the bent hanger (2) on a hook or the like.

また、吊り下げ用の吊り具が上部に取り付けられた医療用容器としては、実公平６−５７９２（特許文献２）に開示されているものがある。
特許文献２に開示されている吊具付き輸液ボトルは、プラスチック製の輸液ボトル１と、ボトル１の底面に取り付けられた吊具を備える。ボトル底面は、周囲の接地面４よりもややくぼんだ状態となっている。吊具は、ボトル底面の中心に中央の溶着部５によって溶着されている。 Further, as a medical container to which a hanging tool for hanging is attached to the upper part, there is one disclosed in Jitsufuku 6-5792 (Patent Document 2).
The infusion bottle with a hanger disclosed in Patent Document 2 includes a plastic infusion bottle 1 and a hanger attached to the bottom surface of the bottle 1. The bottom surface of the bottle is slightly recessed from the surrounding ground plane 4. The hanger is welded to the center of the bottom surface of the bottle by the central welding portion 5.

この溶着部５は円板状のものであり、その一端にボトル底面の長辺方向に延びる一対の短片６、６を備えている。そしてこれらの短片６、６の先端からボトル中心を越えて反対側に延びる一対のアーム７、７が形成されている。アーム７、７はボトル底面１の短辺方向に延びている。そして、アーム７、７の先端どうしを結ぶように、環状の把手部８が一体に形成されている。この把手部８はボトル中心を再度反対方向に越えて中央の溶着部１及び短片６、６の外側をまわるように形成されている。なお折曲部９、１０の間の部分はやや薄肉に形成され、変形し易くなっている。 The welded portion 5 has a disk shape, and has a pair of short pieces 6 and 6 extending in the long side direction of the bottom surface of the bottle at one end thereof. A pair of arms 7 and 7 extending from the tips of these short pieces 6 and 6 beyond the center of the bottle to the opposite side are formed. The arms 7 and 7 extend in the direction of the short side of the bottom surface 1 of the bottle. An annular handle portion 8 is integrally formed so as to connect the tips of the arms 7 and 7. The handle portion 8 is formed so as to cross the center of the bottle again in the opposite direction and go around the outer side of the central welded portion 1 and the short pieces 6 and 6. The portion between the bent portions 9 and 10 is formed to be slightly thin and easily deformed.

特許３５９４２８０号公報Japanese Patent No. 3594280 実公平６−５７９２号公報Jitsufuku No. 6-5792

特許文献１のものでは、図３及び図４に示す容器を吊り下げる場合は、容器本体（１）の底面（１５）に取り付けられた吊り具（２）の枠部（２１）を折り曲げることにより、底面（１５）から突出する略三角形状の１組のベルトを形成することが必要である。しかし、容器本体の上部に近接する吊り具（２）の枠部（２１）を折り曲げることは困難であり、場合によっては、吊り具（２）の枠部と容器本体との間に平板状のものを挿入して、引き起こす必要がある。また、吊り具（２）が、容器本体（１）の底面（１５）の凹没部分にほぼ嵌合する形状のため、折り曲げた吊り具（２）の一部が底面（１５）の折返し部（１５Ｃ）に引っ掛かり、吊下部材を基点として吊具付容器を回動させ難い恐れがある。
また、特許文献１のものでは、吊り具（２）の枠部（２１）を折り曲げ後、折り曲げ形状の維持が十分ではなく、折り曲げ前形状に戻りやすく、スタンドへの懸架作業が容易ではなく、また、吊り具（２）の枠部（２１）の懸架時の耐久性にも問題があった。 In Patent Document 1, when the container shown in FIGS. 3 and 4 is hung, the frame portion (21) of the hanger (2) attached to the bottom surface (15) of the container body (1) is bent. , It is necessary to form a set of substantially triangular belts protruding from the bottom surface (15). However, it is difficult to bend the frame portion (21) of the hanging tool (2) close to the upper part of the container body, and in some cases, a flat plate shape is formed between the frame portion of the hanging tool (2) and the container body. You need to insert something and provoke it. Further, since the hanger (2) has a shape that substantially fits into the recessed portion of the bottom surface (15) of the container body (1), a part of the bent hanger (2) is a folded portion of the bottom surface (15). It may be caught in (15C) and it may be difficult to rotate the container with the hanging tool with the hanging member as a base point.
Further, in Patent Document 1, after bending the frame portion (21) of the hanging tool (2), the bent shape is not sufficiently maintained, the shape before bending is easily returned, and the suspension work on the stand is not easy. In addition, there is also a problem in the durability of the frame portion (21) of the hanging tool (2) when suspended.

また、特許文献２の吊具付輸液ボトルにおける吊具のように、吊具自体は、ボトルの底面に固定されるものであるため、大きいものとすることができず、また、環状の把手部およびアーム部を変形させて、吊下可能部を形成する必要があるため、それらは比較的細い構成部材により形成されている。そして、輸液ボトルは、スタンドの上部に、ねじで固定された懸垂棒に吊り下げて使用される。このため、環状把手部の上端部に輸液ボトルの全荷重が付与される。
そして、特許文献２のものでも、アーム部は、変形後、変形形状の維持が難しく、変形前形状に戻りやすく、スタンドへの懸架作業が容易ではなく、また、アーム部の懸架時の耐久性にも問題があった。 Further, unlike the hanger in the infusion bottle with a hanger of Patent Document 2, the hanger itself is fixed to the bottom surface of the bottle, so that it cannot be made large, and the annular handle portion. And because it is necessary to deform the arm portion to form a suspendable portion, they are formed of relatively thin components. Then, the infusion bottle is used by hanging it on a suspension rod fixed with a screw at the upper part of the stand. Therefore, the full load of the infusion bottle is applied to the upper end of the annular handle.
Further, even in Patent Document 2, it is difficult to maintain the deformed shape of the arm portion after deformation, it is easy to return to the shape before deformation, it is not easy to suspend the arm portion to the stand, and the durability of the arm portion when suspended. There was also a problem.

そこで、本発明では、熱可塑性樹脂製容器本体と、容器本体の上部に、回動可能に取り付けられた吊下用部材とを備え、吊下用部材の一部を起立させることにより、輸液用スタンドに吊り下げ可能となる医療用液体収納用容器体であって、吊下用部材の起立のための折り曲げ操作が容易であり、折り曲げ操作後の折り曲げ状態維持も良好であり、かつ、スタンドへの懸架時において十分な耐久性を有し、かつ、良好に回動可能である医療用液体収納用容器体およびそれを用いた薬剤充填済み医療用容器を提供するものである。 Therefore, in the present invention, a container body made of thermoplastic resin and a hanging member rotatably attached to the upper part of the container body are provided, and a part of the hanging member is erected to be used for infusion. It is a medical liquid storage container that can be hung on a stand, and it is easy to bend the hanging member for standing up, it is good to maintain the bent state after the bending operation, and it goes to the stand. It is an object of the present invention to provide a medical liquid storage container body which has sufficient durability and is satisfactorily rotatable when suspended, and a drug-filled medical container using the same.

The base portion 41 has a plate shape having a central portion 44 having a through hole 45 through which the pin-shaped protrusion 23 of the container body 2 penetrates and two side end portions located on both sides of the central portion 44. ..

懸架部４２は、ベース部４１の一方の側端部に始端を有し、他方の側端部に終端を有するＵ字状のものとなっており、かつ、始端および終端のそれぞれに設けられた折り曲げ可能な２つの折り曲げ部４３ａ，４３ｂを有し、２つの折り曲げ部４３ａ，４３ｂを介してベース部４１の側端部と連結している。吊下用部材４は、２つの折り曲げ部４３ａ，４３ｂで屈曲させることにより、懸架部４２を上方に向かって起立可能である。これにより、懸架部４２内に吊下部１４が形成されるものとなっている。懸架部４２は、懸架部として機能する。 The suspension portion 42 has a U-shape having a start end at one side end of the base portion 41 and an end at the other side end, and is provided at each of the start end and the end. It has two foldable portions 43a and 43b, and is connected to the side end portion of the base portion 41 via the two foldable portions 43a and 43b. By bending the suspension member 4 at the two bent portions 43a and 43b, the suspension portion 42 can be erected upward. As a result, the suspension portion 14 is formed in the suspension portion 42. The suspension portion 42 functions as a suspension portion.

この実施例では、吊下用部材４は、熱可塑性樹脂を用いて射出成形により作成されている。そして、発明者が検討したところ、吊下用部材４の物性が、高圧蒸気滅菌（例えば、温度条件１１５℃）の前後において相違することを知見した。この要因は、明確ではないが、上記の高圧蒸気滅菌後において、ポリエチレンは硬くなり、ポリプロピレンは柔らかくなる傾向があることを本願発明者が知見した。
そして、本発明において用いる吊下用部材４は、１１５℃の高圧蒸気滅菌後における、引張降伏応力が２５ＭＰａ以上、破断伸度が１００％以上である。このため、十分な強度と伸度を備えるため、スタンド懸架時において、薬液が融点された容器本体を十分に保持可能である。 In this embodiment, the hanging member 4 is made by injection molding using a thermoplastic resin. Then, as a result of examination by the inventor, it was found that the physical properties of the hanging member 4 differ before and after high-pressure steam sterilization (for example, temperature condition 115 ° C.). Although this factor is not clear, the inventor of the present application has found that polyethylene tends to be hard and polypropylene tends to be soft after the above-mentioned high-pressure steam sterilization.
The suspension member 4 used in the present invention has a tensile yield stress of 25 MPa or more and a breaking elongation of 100% or more after high-pressure steam sterilization at 115 ° C. Therefore, since it has sufficient strength and elongation, it is possible to sufficiently hold the container body in which the chemical solution has a melting point when the stand is suspended.

さらに、吊下用部材４は、１１５℃高圧蒸気滅菌後における、引張降伏応力が２５ＭＰａ以上、破断伸度が１００％以上であり、かつ、折り曲げ部４３において、ベース部４１の下面と懸架部４２の上面間の角度が１５０度となるように押圧して折り曲げ、押圧解除１分後のベース部４１と懸架部４２間の上記角度が、６０度以上を維持するものであることが好ましい。 Further, the suspension member 4 has a tensile yield stress of 25 MPa or more and a breaking elongation of 100% or more after high-pressure steam sterilization at 115 ° C., and in the bent portion 43, the lower surface of the base portion 41 and the suspension portion 42. It is preferable that the angle between the upper surfaces of the base portion 41 and the suspension portion 42 is maintained at 60 degrees or more after 1 minute of pressing and bending so that the angle between the upper surfaces thereof is 150 degrees.

そして、吊下用部材は、上記の高圧蒸気滅菌後における引張降伏応力が３０ＭＰａ以上であり、破断伸度が２００％以上であることが好ましい。また、高圧蒸気滅菌後における引張降伏応力が５０ＭＰａ以下であり、破断伸度が３００％以下であることが好ましい。 The suspension member preferably has a tensile yield stress of 30 MPa or more and a breaking elongation of 200% or more after the above-mentioned high-pressure steam sterilization. Further, it is preferable that the tensile yield stress after high-pressure steam sterilization is 50 MPa or less and the elongation at break is 300% or less.

そして、吊下用部材４は、上記の高圧蒸気滅菌後において、折り曲げ部４３ａ，４３ｂにて、ベース部４１の下面と懸架部４２の上面間の角度が１５０度となるように押圧して折り曲げ、押圧解除１分後のベース部４１と懸架部４２間の上記角度が、６０度以上維持するものとなっている。このため、折り曲げ操作後において、懸架部４２は、ベース部４１に対して所定角度折れ曲がった状態を保持すので、懸架部４２内により形成された吊下部１４をスタンドに懸架する作業が容易である。 Then, after the above-mentioned high-pressure steam sterilization, the suspension member 4 is bent by pressing the bent portions 43a and 43b so that the angle between the lower surface of the base portion 41 and the upper surface of the suspension portion 42 is 150 degrees. The angle between the base portion 41 and the suspension portion 42 one minute after the pressing is released is maintained at 60 degrees or more. Therefore, after the bending operation, the suspension portion 42 keeps the state of being bent at a predetermined angle with respect to the base portion 41, so that the work of suspending the suspension lower portion 14 formed in the suspension portion 42 on the stand is easy. ..

特に、吊下用部材４は、上記の高圧蒸気滅菌後において、押圧解除３分後のベース部４１と懸架部４２間の上記角度が、６０度以上維持するものが好ましい。さらには、押圧解除５分後のベース部４１と懸架部４２間の上記角度が、６０度以上を維持するものが好ましい。
さらに、この実施例の吊下用部材４は、貫通孔保有部４４の端部に、凹部６７が設けられており、この凹部６７の中心には、ゲート跡を有している。 In particular, the suspension member 4 preferably maintains the angle between the base portion 41 and the suspension portion 42 at 60 degrees or more after 3 minutes from the release of pressing after the above-mentioned high-pressure steam sterilization. Further, it is preferable that the angle between the base portion 41 and the suspension portion 42 5 minutes after the release of pressing is maintained at 60 degrees or more.
Further, the hanging member 4 of this embodiment is provided with a recess 67 at the end of the through hole holding portion 44, and has a gate mark at the center of the recess 67.

さらに、この実施例の医療用液体収納用容器体１では、図５に示すように、吊下用部材４が最も下方に位置した状態（言い換えれば、吊下用部材４が最も容器本体２の上面に近接する状態）においても、折り曲げ部４３（４３ａ，４３ｂ）で屈曲させる前の状態において、吊下用部材４の懸架部４２の下面と容器本体２の上面との間に隙間１５を有するものとなっている。 Further, in the medical liquid storage container 1 of this embodiment, as shown in FIG. 5, the suspension member 4 is located at the lowest position (in other words, the suspension member 4 is the most container body 2). Even in the state of being close to the upper surface), there is a gap 15 between the lower surface of the suspension portion 42 of the hanging member 4 and the upper surface of the container body 2 in the state before being bent by the bent portions 43 (43a, 43b). It has become a thing.

このため、懸架部４２の端部に指先を引掛けやすくなり、懸架部４２の起立操作が容易になる。なお、この隙間１５は、折り曲げ部４３（４３ａ，４３ｂ）を屈曲させる前の状態において、吊下用部材４の懸架部４２の少なくともベース部４１側と反対側の端部の下面と容器本体２の上部２６との間に形成されていればよい。また、この隙間１５は、折り曲げ部４３（４３ａ，４３ｂ）で屈曲させる前の状態において、懸架部４２の下面全体と容器本体２の上部２６との間に形成されていることが好ましい。 Therefore, it becomes easy to hook the fingertip on the end portion of the suspension portion 42, and the standing operation of the suspension portion 42 becomes easy. In addition, this gap 15 is the lower surface of the end portion of the suspension portion 42 of the suspension member 4 at least on the side opposite to the base portion 41 side and the container body 2 in the state before the bent portions 43 (43a, 43b) are bent. It suffices if it is formed between the upper part 26 of the. Further, it is preferable that the gap 15 is formed between the entire lower surface of the suspension portion 42 and the upper portion 26 of the container body 2 in a state before being bent by the bent portions 43 (43a, 43b).

また、この実施例の医療用液体収納用容器体１では、図１および図５に示すように、折り曲げ部４３（４３ａ，４３ｂ）で屈曲させる前の状態において、吊下用部材４の懸架部４２の下面と容器本体２の上面との間の隙間１５は、懸架部４２の端部に向かって、具体的には、懸架部４２のベース部４１側と反対側の端部に向かって徐々に広がるものとなっている。よって、懸架部４２の起立操作時に上方に押される端部は、特に広い隙間を有しており、起立操作がさらに容易なものとなっている。 Further, in the medical liquid storage container 1 of this embodiment, as shown in FIGS. 1 and 5, the suspension portion of the suspension member 4 is in a state before being bent by the bent portions 43 (43a, 43b). The gap 15 between the lower surface of the suspension portion 42 and the upper surface of the container body 2 gradually approaches the end portion of the suspension portion 42, specifically, the end portion of the suspension portion 42 opposite to the base portion 41 side. It has become widespread. Therefore, the end portion pushed upward during the standing operation of the suspension portion 42 has a particularly wide gap, which makes the standing operation easier.

さらに、この実施例の医療用液体収納用容器体１では、図５の状態において、吊下用部材４をピン状突起２３の上部（上端）方向に押し上げることにより、図１の状態となるまで、すなわち、吊下用部材４が膨出部２４の下面に当接するまで、容器本体２の上面より離間する方向に移動する。これにより、吊下用部材４の懸架部４２の下面と容器本体２の上面との間の隙間１５は、さらに広がるため、起立操作がさらに容易となり、かつ、吊下用部材４の回動が容易かつ確実なものとなっている。 Further, in the medical liquid storage container 1 of this embodiment, in the state of FIG. 5, the hanging member 4 is pushed up toward the upper part (upper end) of the pin-shaped protrusion 23 until the state of FIG. 1 is reached. That is, the hanging member 4 moves in a direction away from the upper surface of the container body 2 until it comes into contact with the lower surface of the bulging portion 24. As a result, the gap 15 between the lower surface of the suspension portion 42 of the suspension member 4 and the upper surface of the container body 2 is further widened, so that the standing operation becomes easier and the suspension member 4 can rotate. It is easy and reliable.

吊下用部材４は、図１ないし図４、図１３ないし図１５に示すように、容器本体２の上面に、回動可能に取り付けられている。
吊下用部材４は、図６ないし図１５に示すように、貫通孔４５を有するベース部４１、２つの折り曲げ部４３ａ，４３ｂ、各折り曲げ部４３ａ，４３ｂの先端と連結したＵ字状の懸架部４２を備えている。 As shown in FIGS. 1 to 4, 13 to 15, the hanging member 4 is rotatably attached to the upper surface of the container body 2.
As shown in FIGS. 6 to 15, the suspension member 4 is a U-shaped suspension connected to a base portion 41 having a through hole 45, two bent portions 43a and 43b, and the tips of the bent portions 43a and 43b. The part 42 is provided.

ベース部４１は、図８、図９、図１３および図１４に示すように、吊下用部材４の一端側を形成し、懸架部４２は、ベース部４１と向かい合い、吊下用部材の他端側を形成している。そして、２つの折り曲げ部４３ａ，４３ｂは、ベース部４１と懸架部４２間に存在するものとなっている。そして、２つの折り曲げ部４３ａ，４３ｂが屈曲する部分を結ぶ仮想線Ｘは、貫通孔４５の中心軸付近を通過するものとなっている。このようにすることにより、２つの屈曲部４３ｃと貫通孔４５の中心軸（言い換えれば、ピン状突起の中心軸）がほぼ直線上となるため、医療用液体収納用容器体１の吊り下げ状態がより安定したものとなる。 As shown in FIGS. 8, 9, 13, and 14, the base portion 41 forms one end side of the suspension member 4, and the suspension portion 42 faces the base portion 41 and other than the suspension member. It forms the end side. The two bent portions 43a and 43b exist between the base portion 41 and the suspension portion 42. The virtual line X connecting the bent portions of the two bent portions 43a and 43b passes near the central axis of the through hole 45. By doing so, the central axes of the two bent portions 43c and the through hole 45 (in other words, the central axes of the pin-shaped protrusions) are substantially linear, so that the medical liquid storage container 1 is suspended. Becomes more stable.

ベース部４１は、略矩形状の平板状のものとなっている。そして、この実施例の吊下用部材４は、図６、図７、図９および図１４に示すように、ベース部４１の下面４１ｂに下方（容器本体２の上面方向）に延びる下面突出部４６ａ，４６ｂを有している。図５に示すように、この下面突出部４６ａ，４６ｂを有することにより、吊下用部材４が最も容器本体２の上面に近接した状態においても、懸架部４２の下面と容器本体２の上面との間に隙間１５を有する。さらに、この実施例吊下用部材４では、図７、図９、図１０および図１２に示すように、下面突出部４６ａ，４６ｂ間に設けられた突出部６８を備えている。このため、ベース部４１の下面部はより安定したものとなっている。そして、この実施例の吊下用部材４では、ベース部４１の上面４１ａは、ほぼ平坦面となっている。そして、中央部４４（言い換えれば、貫通孔４５の周縁部）の上面は、ベース部４１の他の部分の上面４１ａより突出した肉厚部となっている。 The base portion 41 has a substantially rectangular flat plate shape. Then, as shown in FIGS. 6, 7, 9, and 14, the hanging member 4 of this embodiment has a lower surface protruding portion extending downward (toward the upper surface of the container body 2) from the lower surface 41b of the base portion 41. It has 46a and 46b. As shown in FIG. 5, by having the lower surface protruding portions 46a and 46b, even when the hanging member 4 is closest to the upper surface of the container body 2, the lower surface of the suspension portion 42 and the upper surface of the container body 2 There is a gap 15 between the two. Further, as shown in FIGS. 7, 9, 10 and 12, the suspension member 4 of the embodiment includes a protrusion 68 provided between the lower surface protrusions 46a and 46b. Therefore, the lower surface portion of the base portion 41 is more stable. In the hanging member 4 of this embodiment, the upper surface 41a of the base portion 41 is a substantially flat surface. The upper surface of the central portion 44 (in other words, the peripheral edge portion of the through hole 45) is a thick portion protruding from the upper surface 41a of the other portion of the base portion 41.

特に、この実施例の吊下用部材４では、下面突出部４６ａ，４６ｂは、ベース部４１の下面４１ｂかつ２つの角部からベース部４１の他端付近まで延びるものとなっている。また、下面突出部４６ａ，４６ｂは、連続するものであってもよい。なお、下面突出部としては、吊下用部材４の下面と容器本体２の上部２６間への板状体（例えば、スリットを有する側壁を備えた容器トレイのスリット部分の側壁）の進入が防止できるものであることが好ましい。例えば、ベース部４１の下面４１ｂの外縁に形成された連続しない複数のリブからなるものであってもよい。そして、この複数のリブにより構成する場合には、ベース部４１の他端付近に位置するリブと、各折り曲げ部４３ａ，４３ｂに近接するリブを備えることが好ましい。また、ベース部の下面全体を突出部としてもよい。 In particular, in the hanging member 4 of this embodiment, the lower surface protruding portions 46a and 46b extend from the lower surface 41b of the base portion 41 and the two corner portions to the vicinity of the other end of the base portion 41. Further, the lower surface protruding portions 46a and 46b may be continuous. The lower surface projecting portion prevents the plate-shaped body (for example, the side wall of the slit portion of the container tray having the side wall having the slit) from entering between the lower surface of the hanging member 4 and the upper portion 26 of the container body 2. It is preferable that the product can be used. For example, it may be composed of a plurality of discontinuous ribs formed on the outer edge of the lower surface 41b of the base portion 41. When it is composed of the plurality of ribs, it is preferable to include ribs located near the other end of the base portion 41 and ribs close to the bent portions 43a and 43b. Further, the entire lower surface of the base portion may be a protruding portion.

懸架部４２は、図８、図９、図１３、図１４および図１５に示すように、Ｕ字状に形成されており、２つの足部（基端部）は、後述する各折り曲げ部４３ａ，４３ｂの先端と連結している。この懸架部４２は、Ｕ字状の頭部（先端部）側をベース部方向に押し上げることにより、各折り曲げ部４３ａ，４３ｂが屈曲し、起立する。そして、起立した懸架部４２は、図１３および図１４に示すように、内部に広い開口部を有し、輸液容器ハンガーのフックに吊下可能な吊下部として機能する。 As shown in FIGS. 8, 9, 13, 14, and 15, the suspension portion 42 is formed in a U shape, and the two foot portions (base end portions) are each bent portion 43a described later. , 43b is connected to the tip. By pushing up the U-shaped head (tip portion) side toward the base portion of the suspension portion 42, the bent portions 43a and 43b are bent and stand up. Then, as shown in FIGS. 13 and 14, the upright suspension portion 42 has a wide opening inside and functions as a suspension portion that can be suspended from the hook of the infusion container hanger.

また、この実施例の吊下用部材４では、図６および図８に示すように、懸架部４２は、中央部４４と向かい合う周縁部、すなわち、ベース部４１側と反対側の端部が肉厚部となっている。このような肉厚部を設けることにより、懸架部４２の湾曲部の強度が高くなる。具体的には、吊下用部材４のスタンドへの吊下時に、懸架部４２のベース部４１側と反対側の端部が輸液容器ハンガーのフックに巻き付くように変形することが防止され、医療用液体収納用容器体１に鉛直方向下向きの荷重がかかった際に、吊下用部材４がより破損し難くなる。 Further, in the suspension member 4 of this embodiment, as shown in FIGS. 6 and 8, the suspension portion 42 has a peripheral portion facing the central portion 44, that is, an end portion on the opposite side to the base portion 41 side. It is a thick part. By providing such a thick portion, the strength of the curved portion of the suspension portion 42 is increased. Specifically, when the suspension member 4 is suspended from the stand, the end portion of the suspension portion 42 opposite to the base portion 41 side is prevented from being deformed so as to wrap around the hook of the infusion container hanger. When a load downward in the vertical direction is applied to the medical liquid storage container 1, the hanging member 4 is less likely to be damaged.

Then, in this embodiment, the thick portion is formed by the upper surface protruding portion 49 provided on the upper surface of the suspension portion 42. In other words, the upper surface protruding portion (thick portion) 49 forms a rib protruding upward in the state before the suspension portion 42 is erected. As shown in FIG. 11, the upper surface protruding portion 49 forming the thick portion is predetermined from the center of the curved portion (in other words, the end portion on the opposite side to the base portion 41 side) of the suspension portion 42 toward both side portions. It is formed to extend long.

さらに、この実施例の吊下用部材４では、懸架部４２は、図８、図９に示すように、上面４１ａ側にＵ字状溝部５１が設けられており、下面側は、連続しないＵ字状の溝部６３が設けられている。下面４１ｂ側の溝部６３は、３つの溝部により構成されており、それらを繋ぐとＵ字状となる。そして、懸架部４２の頂点（ベース部４１側と反対側の端部）部分は、図１０に示すように、上記の肉厚部（上面突出部４９）、上面側のＵ字状溝部５１および下面側の溝部６３を有することにより、断面がＨ状形状を有するものとなっており、高い強度を有している。 Further, in the suspension member 4 of this embodiment, as shown in FIGS. 8 and 9, the suspension portion 42 is provided with a U-shaped groove portion 51 on the upper surface 41a side, and the lower surface side is a discontinuous U. A character-shaped groove 63 is provided. The groove 63 on the lower surface 41b side is composed of three grooves, and when they are connected, a U-shape is formed. Then, as shown in FIG. 10, the apex portion (the end portion on the side opposite to the base portion 41 side) of the suspension portion 42 includes the above-mentioned thick portion (upper surface protruding portion 49), the U-shaped groove portion 51 on the upper surface side, and the portion. By having the groove portion 63 on the lower surface side, the cross section has an H-shaped shape and has high strength.

吊下用部材４は、図８、図９、図１１、図１２、図１３および図１４に示すように、２つの折り曲げ部（言い換えれば、屈曲可能部、折曲可能部）４３ａ，４３ｂを備えている。折り曲げ部４３ａ，４３ｂは、ベース部４１の先端部の両側部より所定幅にて延びるものとなっている。そして、各折り曲げ部４３ａ，４３ｂは、図６、図１０および図１２に示すように、ベース部４１および懸架部４２に比べて薄肉部となっている。さらに、この実施例では、図６に示すように、各折り曲げ部４３ａ，４３ｂは、その中央部が、最も肉薄となっているため、折り曲げ部は、その中央部において図１３および図１４に示すように屈曲する。 As shown in FIGS. 8, 9, 12, 12, 13 and 14, the hanging member 4 has two bent portions (in other words, a bendable portion and a bendable portion) 43a and 43b. I have. The bent portions 43a and 43b extend by a predetermined width from both side portions of the tip portion of the base portion 41. As shown in FIGS. 6, 10 and 12, each of the bent portions 43a and 43b is a thin portion as compared with the base portion 41 and the suspension portion 42. Further, in this embodiment, as shown in FIG. 6, since the central portion of each of the bent portions 43a and 43b is the thinnest, the bent portion is shown in FIGS. 13 and 14 at the central portion thereof. Bend like.

吊下用部材４は、図８ないし図１５に示すように、ピン状突起２３の外径より若干大きい内径を有し、ピン状突起２３が貫通する貫通孔４５を有する中央部４４を備えている。中央部４４は、ベース部４１の一端より、懸架部４２方向に突出するものとなっている。中央部４４は、中央部に貫通孔４５を備えている。貫通孔４５は、ピン状突出部２３の外径より若干大きい内径を有している。また、中央部４４の上面は、平坦面となっている。 As shown in FIGS. 8 to 15, the suspension member 4 has an inner diameter slightly larger than the outer diameter of the pin-shaped protrusion 23, and includes a central portion 44 having a through hole 45 through which the pin-shaped protrusion 23 penetrates. There is. The central portion 44 projects from one end of the base portion 41 in the direction of the suspension portion 42. The central portion 44 is provided with a through hole 45 in the central portion. The through hole 45 has an inner diameter slightly larger than the outer diameter of the pin-shaped protrusion 23. The upper surface of the central portion 44 is a flat surface.

また、この実施例の吊下用部材４では、図８、図９、図１２に示すように、底面側に設けられた円弧状凹部４８を備えている。また、この円弧状凹部４８により、上面側に向かって拡径するテーパー部４７が形成されている。円弧状凹部４８は、貫通孔４５より若干離間し、かつ実質的に貫通孔４５と同心的となるように形成されている。このような円弧状凹部４８および筒状部４７を設けることにより、吊下用部材の側部への衝撃付与時、懸架部４２の起立操作時におけるピン状突起２３の破損を防止する。具体的には、円弧状凹部４８と貫通孔４５間の筒状部が、緩衝部として機能するため、吊下用部材に付与された力がピン状突起２３に伝達されることを抑制する。 Further, as shown in FIGS. 8, 9, and 12, the hanging member 4 of this embodiment is provided with an arcuate recess 48 provided on the bottom surface side. Further, the arcuate concave portion 48 forms a tapered portion 47 whose diameter increases toward the upper surface side. The arcuate recess 48 is formed so as to be slightly separated from the through hole 45 and substantially concentric with the through hole 45. By providing such an arcuate recess 48 and a tubular portion 47, it is possible to prevent the pin-shaped protrusion 23 from being damaged when an impact is applied to the side portion of the suspension member and when the suspension portion 42 is raised. Specifically, since the tubular portion between the arcuate concave portion 48 and the through hole 45 functions as a cushioning portion, the force applied to the hanging member is suppressed from being transmitted to the pin-shaped projection 23.

そして、吊下用部材４は、図８ないし図１５に示すように、中央部４４と懸架部４２間に設けられた空隙部（吊下部）１４を備えている。この実施例の吊下用部材４では、中央部４４の先端と懸架部４２の先端部の内面間は、十分に離間しており、かなり広い空隙部１４となっている。さらに、この実施例の吊下用部材４は、空隙部１４と連続し、中央部４４と各折り曲げ部４３ａ，４３ｂ間に位置する２つのスリット部１４ａ，１４ｂを有している。中央部４４と各折り曲げ部４３ａ，４３ｂ間にスリット部１４ａ，１４ｂが設けられていることにより、言い換えれば、中央部４４と各折り曲げ部４３ａ，４３ｂが、スリット部１４ａ，１４ｂにより分断されていることにより、折り曲げ部における屈曲が容易かつ確実なものとなっている。そして、折り曲げ部４３ａ、４３ｂ間に、貫通孔保有部を有するため、吊り下げ状態が安定したものとなる。 Then, as shown in FIGS. 8 to 15, the suspension member 4 includes a gap portion (suspension lower portion) 14 provided between the central portion 44 and the suspension portion 42. In the suspension member 4 of this embodiment, the tip of the central portion 44 and the inner surface of the tip of the suspension portion 42 are sufficiently separated to form a fairly wide gap portion 14. Further, the hanging member 4 of this embodiment has two slit portions 14a and 14b that are continuous with the gap portion 14 and are located between the central portion 44 and the bent portions 43a and 43b. Since the slit portions 14a and 14b are provided between the central portion 44 and the bent portions 43a and 43b, in other words, the central portion 44 and the bent portions 43a and 43b are separated by the slit portions 14a and 14b. As a result, bending at the bent portion is easy and reliable. Further, since the through hole holding portion is provided between the bent portions 43a and 43b, the suspended state becomes stable.

さらに、この実施例の吊下用部材４では、図１３および図１４に示すように、折り曲げ部４３ａ，４３ｂにて屈曲させて、起立用操作部４２を起立させた状態における折り曲げ部４３ａ，４３ｂの屈曲部４３ｃを結ぶ仮想線Ｘ（図８および図１３）は、貫通孔４５の中心付近を通過するものとなっている。このようにすることにより、２つの屈曲部４３ｃと貫通孔４２の中心（言い換えれば、ピン状突起の中心）がほぼ直線上となるため、吊り下げ状態がより安定したものとなる。 Further, in the hanging member 4 of this embodiment, as shown in FIGS. 13 and 14, the bent portions 43a and 43b are bent at the bent portions 43a and 43b so that the standing operation portion 42 is erected. The virtual line X (FIGS. 8 and 13) connecting the bent portion 43c of the above passes through the vicinity of the center of the through hole 45. By doing so, the centers of the two bent portions 43c and the through holes 42 (in other words, the centers of the pin-shaped protrusions) are substantially on a straight line, so that the suspended state becomes more stable.

そして、この実施例の医療用液体収納用容器体１は、図１、図３、図４、図１３および図１４に示すように、吊下用部材４の全体は、容器本体２の上部２６よりも上方に位置している。そして。折り曲げ部４３（４３ａ，４３ｂ）で屈曲させる前の状態において、懸架部４２の少なくともベース部４１側と反対側の端部（言い換えれば、懸架部４２の湾曲部）の下面４１ｂと容器本体２の上部２６との間に隙間を有するものとなっている。 Then, as shown in FIGS. 1, 3, 4, 13, and 14, in the medical liquid storage container 1 of this embodiment, the entire suspension member 4 is the upper portion 26 of the container body 2. It is located above. And. In the state before bending by the bent portions 43 (43a, 43b), the lower surface 41b of the end portion (in other words, the curved portion of the suspension portion 42) opposite to at least the base portion 41 side of the suspension portion 42 and the container body 2 It has a gap between it and the upper portion 26.

また、貫通孔保有部４４は、ベース部４１の上面より若干突出した肉厚部となっている。そして、貫通孔保有部４４の端部は、吊下用部材４の一端（言い換えれば、ベース部４１のヒンジ部４３側と反対側の端部）の中央部付近まで延びている。このため、肉厚の貫通孔保有部４４は、貫通孔４５を含むベース部４１の中央部を補強している。また、貫通孔保有部４４は、上記の端部に向かって、幅が徐々に狭くなっている。そして、貫通孔保有部４４の端部には、凹部６７が設けられており、この凹部６７の中心には、ゲート跡を有している。 Further, the through hole holding portion 44 is a thick portion slightly protruding from the upper surface of the base portion 41. Then, the end portion of the through hole holding portion 44 extends to the vicinity of the central portion of one end of the hanging member 4 (in other words, the end portion of the base portion 41 opposite to the hinge portion 43 side). Therefore, the thick through-hole holding portion 44 reinforces the central portion of the base portion 41 including the through-hole 45. Further, the width of the through hole holding portion 44 gradually narrows toward the end portion. A recess 67 is provided at the end of the through hole holding portion 44, and a gate mark is provided at the center of the recess 67.
