Description
【発明の詳細な説明】 〔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。TECHNICAL FIELD The present invention relates to an infusion container. Specifically, it relates to an infusion container used for containing an infusion solution or 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に口栓に空気孔を
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, a glass or synthetic resin bottle has been used as a medical infusion container containing a drip solution, etc., and an air hole is provided in a spout to allow air to enter the bottle as the drip solution decreases. Also, it is known that a flexible synthetic resin container is used, and the shape of the container is deformed as the amount of the drip solution is reduced.
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、また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、さらに完全に出たとしても、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 the above bottle is used, the air in the hospital is mixed into the drip solution, which causes a problem of nosocomial infection, and when the above container is used, the shape of the container decreases as the drip solution decreases. There is a problem that the drip solution inside the container does not completely come out when it is deformed, and even if it completely comes out, there is no regularity in the way the shape is deformed and the outflow rate of the drip solution However, there is also a problem that is different for each 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 above-mentioned problems of the conventional infusion container, and as the drip solution or the like flows out from the infusion container, the container shape is always stably deformed into a constant shape, and the drip solution or the like is kept constant. As a result of intensive studies to provide a container for infusion that can be completely and completely discharged, it is possible to achieve the object by making the cross-sectional shape of the container body a special shape. Heading out, the present invention has been completed.
すなわち、本発明の要旨は吹込成形によって形成され
た壜状の容器であって、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 bottle-shaped container formed by blow molding, wherein three ridge lines are formed by making the cross-sectional shape of the body part substantially triangular, and the ridge lines are formed in the longitudinal direction of the container. It exists in an infusion container characterized by being inclined.
以下、図面を用いて本発明の容器の一例について説明
する。Hereinafter, an example of the container of the present invention will be described with reference to the drawings.
第１図は、本発明の容器の側面図、第２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. 2 is a bottom view of the container shown in FIG.
図中１は輸液用容器、２は口部、３は胴部、4,4′,
4″は稜線をそれぞれ示す。In the figure, 1 is an infusion container, 2 is a mouth part, 3 is a body part, 4, 4 ',
4 ″ indicates ridgelines, respectively.
図示した輸液容器１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 1 is made by blow molding, and an upper portion of the container is a mouth portion 2 having a flange on its peripheral surface.
口部２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１の胴部３に至る。A smooth curved shoulder is formed from the base of the mouth 2,
This shoulder reaches the body 3 of the container 1.
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 3 has a substantially triangular cross-sectional shape, and the ridgeline formed by this 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。That is, the substantially triangular cross section has a shape as if it were rotated while being displaced in the vertical direction.
従つて、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 upper part and the bottom part 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30°〜90°の範
囲である。The angle of the displacement (the angle of twist from the top to the bottom of the body 3) is arbitrary, but is preferably in the range of 30 ° to 90 °.
図示した輸液容器１は、例えば、点滴液を収容し点滴
の際には、口部２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１の内圧が低く
なるに従い、輸液容器１は大気圧により除々に変形して
ゆく。The illustrated infusion container 1 contains, for example, an infusion solution and guides the infusion solution by a tube with the mouth portion 2 facing downward when the infusion is performed. The infusion container 1 is gradually deformed by the atmospheric pressure.
変形は、輸液容器１の胴部３の断面形状が略三角形で
あり、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4,4′,
4″の間の側面部が内側に凹むように変形する。The deformation is such that the body 3 of the infusion container 1 has a substantially triangular cross-sectional shape, and as shown in the figure, the body 3 bulges outward from the straight line connecting the ridges. ′,
The side part between 4 ″ is deformed so as to be recessed 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。In addition, since the ridge line is inclined in the vertical direction during this deformation, the body portion 3 is also twisted during the deformation, which helps the deformation, that is, the outflow of the drip solution.
このように、内容液の流出に伴って生ずる容器１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。As described above, the deformation of the container 1 caused by the outflow of the content liquid is due to the combined effect of the side surface of the body 3 being deformed so as to be recessed and the whole body being deformed so as to be twisted.

二軸延伸ブローボトル等が好適に使用される。また、こ
の輸液用容器は倒置して内容点滴液等を流出させた際、
空気置換を行なわずとも、輸液用容器が流出した点滴液
等の量と同じ量だけ変形して内容量が減少するように、
その壁厚が充分に薄肉とされている。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300〜600μ程
度の肉厚とするのが適当である。The infusion container of the present invention is formed by blow molding such as direct blow molding, stretch blow molding, injection blow molding using a synthetic resin such as polypropylene, polyethylene, polyvinyl chloride and the like. It is desirable that this infusion container be as transparent as possible so that it is possible to visually confirm that impurities, etc. are not mixed in the drip solution in the container, and it is also necessary to withstand heat sterilization up to about 120 ° C. is there. Therefore, for example, a biaxially stretched blow bottle made of polypropylene is preferably used. Also, when this infusion container is inverted and the contents drip solution etc. flow out,
Even if air replacement is not performed, the transfusion container is deformed by the same amount as the amount of drip solution that has flowed out, so that the internal volume decreases.
The wall thickness is sufficiently thin. The wall thickness of the infusion container varies depending on the capacity, required strength, material, etc. of the container, but when polypropylene is used, for example, a wall thickness of about 300 to 600 μ is usually appropriate.
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。Further, the portion to be deformed of the infusion container is mainly the body portion of the container, and the container mouth is preferably not deformed from the viewpoint of operation such as filling of infusion solution or connection of infusion pipe,
That is, it is desirable that the mouth portion of the infusion container is made thick and the shoulder portion, the body portion and the bottom portion of the container are made thin so that the thickness distribution is changed.
本発明の輸送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。Since the shipping container of the present invention uses a synthetic resin thin-walled container, it has excellent transparency, and impurities can be easily found.Because the container is deformed to drop the contents, air replacement is performed when dropping. It is unnecessary, there is no fear of nosocomial infection, the drip rate is stable, and the contents can be completely discharged.
