本発明は輸液用容器に関する。詳しくは点滴液等を収容
す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 containing an intravenous 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■のピン全量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シ、院内感染の問
題があシ、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
があシ、さらに完全に出たとしても、その形状変形の仕
方に定常性がなく、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, if the entire amount of pins mentioned in ■ above are used, the air in the hospital may get mixed into the intravenous fluid, which may lead to the problem of nosocomial infection. When the shape of the container deforms as the container decreases, there is a problem that depending on the way the deformation occurs, the intravenous fluid inside the container may not come out completely, and even if it does come out completely, the way the shape deforms is inconsistent. Another problem is that the outflow rate of the infusion solution 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
特定位置に胴部の変形を促す突条等を設けることにより
、上記目的を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 conventional infusion containers, and as the intravenous fluid, etc. flows out from the infusion container, the shape of the container is always stably deformed to a constant shape, and the infusion fluid, etc. is kept in a constant shape. In order to provide an infusion container that can drain fluids at a relatively high rate and completely, as a result of extensive research, we have achieved the above objectives by providing protrusions at specific positions on the body of the container to encourage deformation of the body. The present inventors have discovered that the following can be achieved, and have completed 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
た壜状の容器であって、胴部の横断面形状が略四角形と
されており、胴部の左右の側面部には、そのほぼ中央部
に外方に突出した突条を上下方向に設け、該突条の両端
部に略三角形の内方に向って凹んだ陥没部を形成したこ
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, in which the cross-sectional shape of the body is approximately square, and the right and left side surfaces of the body have a substantially central portion. The present invention relates to an infusion container characterized in that an outwardly projecting ridge is provided in the vertical direction, and substantially triangular inwardly recessed portions are formed at both ends of the ridge.
以下、本発明の容器の一例につき図面を用いて説明する
。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正面図、第2図は第7図に示し
た容器の側面図、第3図はA−A断面図、第7図はB−
B断面図である。FIG. 1 is a front view of the container of the present invention, FIG. 2 is a side view of the container shown in FIG. 7, FIG. 3 is a sectional view taken along line A-A, and FIG.
It is a sectional view of B.
図中lは輸液用容器、コは口部、3は胴部、グは胴部正
面、左は胴部側面、6は突条、りは陥没部をそれぞれ示
す。In the figure, l indicates an infusion container, C indicates a mouth, 3 indicates a body, G indicates the front of the body, left indicates a side surface of the body, 6 indicates a protrusion, and RI indicates a depressed portion.
図示した輸液用容器lは、容器上部に口部2が形成され
この口部コの周面には、7ランジが設けられている。The illustrated infusion container 1 has a mouth 2 formed in the upper part of the container, and seven lunges are provided on the circumferential surface of the mouth.
口部コの基部よシ、なめらかな曲面の肩部が前後左右に
形成され、この肩部は、容器/の胴部に向って傾斜した
曲面となっている。At the base of the mouth part, shoulders with smooth curved surfaces are formed on the front, back, left and right sides, and these shoulders have curved surfaces that slope toward the body of the container.
胴部3は、その横断面形状が略四角形であシ、胴部3の

い。The body part 3 has a substantially rectangular cross-sectional shape, and a protrusion 6 is provided approximately in the center on the left side of the body part 3 in the vertical direction of the body part. Furthermore, approximately triangular depressions are provided at the upper and lower portions of both ends of the protrusion 6. The depressed portion has a triangular shape with its vertices at both ends of the protrusion 6 and its base in the direction of the shoulder or the bottom 6, respectively. The length of the base of the triangle is preferably about ⅓ to v5 of the width of the side surface 5 of the body.
図示した輸液用容器l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シ点滴液を導
く。The illustrated infusion container 1 stores, for example, an infusion solution, and during infusion, the infusion solution is guided through a tube with the mouth portion 2 facing down.
ここで、点滴の進行によって輸液容器/の内圧が低くな
るに従い、輸液容器/は大気圧によシ除々に変形してい
く。Here, as the internal pressure of the infusion container decreases as the infusion progresses, the infusion container gradually deforms due to atmospheric pressure.
輸液容器lの胴部3には左右側面部3のほぼ中央部に突
条6が胴部の上部から下部にわたシ設けられている為、
液体流出時、突条6が外に向って膨出するように、すな
わち胴部3が扁平につぶれ、胴部正面グと、その対向面
の間隔が狭くなり、接触するように変形する。The body 3 of the infusion container 1 has a protrusion 6 extending from the top to the bottom of the body at approximately the center of the left and right side parts 3.
When the liquid flows out, the protrusions 6 bulge outward, that is, the body 3 is flattened, and the distance between the front tongue of the body and its opposing surface narrows, and the body deforms so that they come into contact with each other.
突条6の上部及び下部には突条とは逆に側面部5の表面
より凹んだ略三角形の陥没部7が設けられており、容器
/の肩部及び底部に近い部分の変形を画一化する働きを
なす。Contrary to the protrusions 6, substantially triangular recesses 7 are provided at the upper and lower parts of the protrusions 6, which are recessed from the surface of the side surface 5, to uniformize the deformation of the parts near the shoulder and bottom of the container. It functions to transform

形は胴部3の側面部5が主となシ、肩部、底部は定形化
することになシ内容液の流出に伴う、内容液表面の垂直
変位が一定になる。As a result, the deformation of the container caused by the outflow of the liquid inside the container is mainly caused by the side surface 5 of the body 3, while the shoulder and bottom parts are shaped. The vertical displacement of the surface becomes constant.

の肉厚とするのが適当である。The infusion container of the present invention is made of synthetic resin such as polypropylene, polyethylene, polyvinyl chloride, etc. by blow molding such as direct blow molding, stretch blow molding, and injection blow molding. 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 in the container, and it is also suitable for heat sterilization up to about 20℃. You also need to be patient. For this reason, for example, a biaxially stretched blow bottle made of polypropylene or the like 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. The wall thickness of an 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 300-400 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

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 and connecting an infusion pipe. , the mouth of the infusion container is thick, the shoulder 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.

易に行なえ、容器の変形によシ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8配がなく

流出させることができる。Since the infusion container of the present invention uses a thin-walled container made of synthetic resin, it has excellent transparency and impurities can be easily detected. Air replacement is not required, there is no risk of in-hospital infection, and the dropping rate is stable, and the contents can be completely drained.
