〔産業上の利用分野〕
本発明は輸液用容器に関する。詳しくは点滴液等の収容
に用いる輸液用容器に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a container for infusion. More specifically, the present invention relates to an infusion container used for storing intravenous fluids and the like.
従来、点滴液等を収容した医療用の輸液用容器としては
■ガラス製又は合成樹脂製のビンを用い、点滴液が減る
にしたがいビン内へ空気が入るよう口栓に空気孔を設け
たもの及び■柔軟な合成樹脂製の容器を用い、点滴液の
減少に従い容器の形状が変形していくものが知られてい
る。Conventionally, medical infusion containers containing intravenous fluids, etc. have been made of glass or synthetic resin bottles, with air holes in the spout to allow air to enter the bottle as the intravenous fluid decreases. and (2) It is known that a container made of flexible synthetic resin is used, and the shape of the container changes as the amount of intravenous fluid decreases.
しかしながら、上記■のビンを用いる場合には病院内の
空気が点滴液の中に混入することとなり、院内感染の問
題があり、まだ上記■の容器を用いる場合には、点滴液
の減少に従って容器の形状が変形する際に、変形の仕方
によっては容器内部の点滴液が完全に出ないという問題
があり、さらに完全に出だとしても、その形状変形の仕
方に規則性がなく、点滴液の流出速度が容器毎に異なる
という問題もある。However, when using the bottle mentioned in (■) above, the air inside the hospital will get mixed into the intravenous fluid, causing the problem of in-hospital infection. When the shape of the container changes, there is a problem that depending on the way the container is deformed, the intravenous fluid inside the container may not come out completely, and even if it does come out completely, there is no regularity in the way the shape deforms, and the intravenous fluid may not come out completely. Another problem is that the outflow rate varies from container to container.
本発明者等は上記した従来の輸液用容器の問題点を解消
し、輸液用容器から点滴液等が流出するに従い容器形状
が常に一定の形状に安定して変形し、点滴液等を一定の
割合で、かつ、完全に流出させることができる輸液用容
器を提供するべく、鋭意検討を重ねた結果、容器胴部の
横断面形状を特殊の形状とすることにより、目的が達成
し得ることを見出し、本発明を完成するに至った。The present inventors have solved the problems of the conventional infusion containers described above, and the shape of the container is always stably deformed into a constant shape as the intravenous solution flows out from the infusion container, and the intravenous solution can be kept in a constant state. In order to provide an infusion container that can drain fluids at a relatively high rate and completely, we have conducted extensive studies and discovered that this goal can be achieved by making the cross-sectional shape of the container body into a special shape. This discovery led to the completion of the present invention.
すなわち、本発明の要旨は吹込成形によって形成された
４状の容器であって、胴部の横断面形状を略三角形とす
ることによって３本の稜線を形成し、該稜線を容器の縦
方向に傾斜させたことを特徴とする輸液用容器に存する
。That is, the gist of the present invention is a four-shaped container formed by blow molding, in which the cross-sectional shape of the body is approximately triangular to form three ridgelines, and the ridgelines are formed in the longitudinal direction of the container. The present invention relates to an infusion container characterized by being tilted.
以下、図面を用いて本発明の容器の一例につき説明する
。An example of the container of the present invention will be described below with reference to the drawings.
第１図は、本発明の容器の側面図、第一図は第１図に示
した容器の底面図である。FIG. 1 is a side view of the container of the present invention, and FIG. 1 is a bottom view of the container shown in FIG.
図中／は輸液用容器、λは口部、３は胴部、＆ 、 ＜
７’、 Ｋ”は稜線をそれぞれ示す。In the figure / is an infusion container, λ is the mouth, 3 is the body, & , <
7' and K'' indicate ridge lines, respectively.
図示した輸液容器／は、吹込成形によって作成されたも
ので、容器上部は周面にフランジを有する口部２とされ
ている。The illustrated infusion container/is made by blow molding, and the upper part of the container has a mouth portion 2 having a flange on the circumferential surface.
口部コの基部よりなめらかな曲面の肩部が形成され、こ
の肩部は容器／の胴部３に至る。A smoothly curved shoulder is formed from the base of the opening, and this shoulder extends to the body 3 of the container.
胴部３は、その横断面形状が略三角形をしており、これ
によって形成される稜線は縦方向に傾斜されている。The body portion 3 has a substantially triangular cross-sectional shape, and the ridgeline formed thereby is inclined in the vertical direction.
すなわち、略三角形の断面があたかも縦方向にずれなが
ら回転したような形状となっている。In other words, the shape is as if the substantially triangular cross section has been rotated while shifting in the vertical direction.
従って、この略三角形の上部と底部はある角度で変位し
ている為容器胴部３が果たしてねじれを加えた形状とな
る。Therefore, since the top and bottom of this substantially triangular shape are displaced at a certain angle, the container body 3 has a twisted shape.
尚、該変位の角度（胴部３の上部から底部までのねじれ
の角度）は任意であるが、好ましくは３００〜９０°の
範囲である。The angle of displacement (the angle of twist from the top to the bottom of the trunk 3) is arbitrary, but is preferably in the range of 300 to 90 degrees.
図示した輸液容器／は、例えば、点滴液を収容し点滴の
際には、口部コを下にしてチューブにより点滴液を導く
、ここで点滴の進行によって輸液容器ｌの内圧が低くな
るに従い、輸液容器／は大気圧により除々に変形してゆ
く。The illustrated infusion container/contains, for example, an infusion solution, and during infusion, the infusion solution is guided through a tube with the mouth facing down.As the infusion progresses, the internal pressure of the infusion container l decreases. The infusion container gradually deforms due to atmospheric pressure.
変形は、輸液容器／の胴部３の断面形状が略三角形であ
シ、しかも図示するように胴部３が稜線を結ぶ直線より
外方に膨出している形状とされているから稜線ｕ４’、
ｌＩ”の間の側面部が内側に凹むように変形する。The deformation is because the cross-sectional shape of the body 3 of the infusion container is approximately triangular, and as shown in the figure, the body 3 bulges outward from the straight line connecting the ridge lines. ,
The side surface between 1I'' is deformed so as to be concave inward.
なお、この変形の際稜線が縦方向に傾斜しているので変
形に際し胴部３にねじれるような変形も加わり、変形す
なわち点滴液の流出を助ける。Note that during this deformation, since the ridge line is inclined in the vertical direction, a twisting deformation is also applied to the body 3 during the deformation, which helps the deformation, that is, the outflow of the intravenous liquid.
このように、内容液の流出に伴って生ずる容器／の変形
は、胴部３の側面部が凹むように変形することと、胴部
全体がねじれるように変形することの併合効果による。In this way, the deformation of the container caused by the outflow of the liquid content is due to the combined effects of the concave deformation of the side surface of the body 3 and the twisting deformation of the entire body.

に、その壁厚が充分に薄肉とされている。The infusion container of the present invention includes polypropylene, polyethylene,
It is molded by blow molding such as direct blow molding, trench blow molding, injection blow molding, etc. using a synthetic resin of PoIJ fg-hibinyl. It is desirable that this infusion container be as transparent as possible so that it can be visually confirmed that there are no impurities mixed in with the intravenous fluid, etc. in the container, and it also needs to be able to withstand heat sterilization up to about 720°C. be. For this reason, for example, a biaxially stretched blow bottle made of polypropylene is preferably used. In addition, when this infusion container is turned upside down and the intravenous fluid, etc. inside it spills out, the infusion container deforms by the same amount as the amount of the drip fluid, etc. that spilled out, even without air replacement, and the content decreases. As such, its wall thickness is sufficiently thin.
輸液用容器の壁厚は容器の容量、必要強度、材質等によ
って異なるが、例えばポリプロピレンを用いた場合には
通常３００〜４００μ程度の肉厚とするのが適当である
。The wall thickness of the infusion container varies depending on the container's capacity, required strength, material, etc., but when polypropylene is used, for example, it is usually appropriate to have a wall thickness of about 300 to 400 μm.
また、輸液用容器の変形すべき部分は該容器の胴部が主
であり、容器口部はむしろ点滴液等の充填、輸液用パイ
プの接続等の操作上から変形しないことが望ましく、す
なわち、輸液用容器の口部を肉厚とし、該容器の肩部、
胴部及び底部は肉薄とするような肉厚分布に変化を持た
せるような構造とするのが望ましい。In addition, the main part of the infusion container that should be deformed is the body of the container, and it is preferable that the opening of the container not be deformed from the viewpoint of operations such as filling with intravenous fluid, connecting an infusion pipe, etc. The mouth of the infusion container is made thick, and the shoulder part of the container,
It is desirable that the body and the bottom have a structure in which the wall thickness distribution varies, such as by making the body thin.
本発明の輸液用容器は合成樹脂製で薄肉とされた容器を
用いるものであるから透明性に優れ、不純物の発見が容
易に行なえ、容器の変形により内容物を滴下する方式な
ので滴下に際し空気置換が不要で院内感染の心配がなく
、さらに滴下速度が安定しており、且つ内容物を完全に
流出させることができる。The infusion container of the present invention uses a thin-walled container made of synthetic resin, so it has excellent transparency and impurities can be easily detected.Since the container is deformed, the contents are dripped, so air is replaced during dripping. There is no need to worry about in-hospital infection, and the dropping rate is stable, and the contents can be completely drained.
