る。[Detailed description of the invention] [Industrial application field] The present invention is particularly directed to a synthetic resin injection container for storing physiological saline, blood substitutes such as Ringer's solution, sugar solutions, protein-amino acid solutions, or other injection solutions. Regarding.

して内容液が汚染されるという問題がある。
Traditionally, glass bottles were often used as containers for this type of injection, but glass bottles were difficult to handle due to their easy breakage, heavy weight, and difficulty in disposing of empty containers. In recent years, blow-molded bottles made of synthetic resins such as polyethylene or polypropylene have been widely used. However, like glass bottles, blow-molded bottles create a negative pressure inside the container when the liquid inside the bottle is drained without using a ventilation needle, and the outflow of the liquid stops. For this reason, it is necessary to supply outside air into the container using a ventilation needle, but in this case, there is a problem that bacteria and dust in the atmosphere flow into the container together with the outside air, contaminating the liquid content.
この問題に対して通気針を使用しないで、内容
液が排出する形式のブロー成形壜が提案されてい
る。この形式の容器においては、柔軟性のある素
材を用いることにより、内容液の排出に伴つて、
容器の胴部が偏平に潰れうる構造となつている。 To solve this problem, a blow-molded bottle has been proposed in which the liquid inside is discharged without using a ventilation needle. In this type of container, by using a flexible material, as the content liquid is drained,
The body of the container is designed to be flattened.
しかしながら、通気針を使用しないで内容液が

て確認することができなかつた。
However, in the structure of conventional blow-molded bottles in which the liquid is discharged without using a ventilation needle, the cross-sectional shape of the container body is constant from the bottom to the shoulder, so the liquid in the bottle is actually discharged. When the container is drained, the container collapses flat from the center of the container and the liquid content decreases, but the liquid remains at the top of the container and the liquid level does not drop, making it possible to visually check the exact amount of remaining liquid. I was unable to confirm this.
更に上記した従来の構成のものでは、内容液の
みの場合と、これに他の注射液を加えた場合のよ
うに内容量の大小に対応して変形する形状をとる
ことができない。したがつて、内容液のある容器
に他の薬剤をさらに混注する場合は、通気針を使
用して容器内の空気を排出する必要があつた。 Furthermore, with the above-mentioned conventional configuration, it is not possible to take a shape that deforms depending on the size of the internal volume, such as when only the internal liquid is contained or when other injection liquid is added to it. Therefore, when co-injecting another drug into a container containing liquid, it is necessary to use a ventilation needle to expel the air inside the container.
そこで本考案者は、以上の従来技術の問題点を
解決するため、先に、通気針を使用することなく

Therefore, in order to solve the above-mentioned problems of the conventional technology, the inventor of the present invention first proposed a method that allows co-injection of other injection liquids or discharge of the liquid content without using a ventilation needle, and furthermore, allows the injection of other injection liquids or the discharge of the liquid content without using a ventilation needle. We proposed a container for injections that allows for accurate visual confirmation of the amount of remaining liquid (Utility Application No. 162136, 1983, Utility Model Application No. 162136,
No. 70525).

本発明に到達したものである。 As a result of further study, the inventor of the present invention found that it is possible to co-inject other injection liquids without using a ventilation needle, or to discharge the contents without using a vent needle. In the production, management, storage, and conservation processes of containers, the sides of the container should be designed in a nearly straight line from the shoulder to the bottom, i.e., the long axis of the oval shape of the body should be found that it is advantageous to keep it constant,
This has led to the present invention.

容器に関する。 That is, the present invention is a synthetic resin container having a hanging device at one end, a pouring outlet at the other end, and an oval cross-sectional shape of the container body. The cross-sectional elliptical shape of the intermediate body part between is an elliptical shape that is flatter than the shoulder part and the bottom part over the entire area,
This invention relates to a synthetic resin injection container in which the length of the long axis of the oval shape of the container body extending from the container shoulder to the container bottom is constant.

針に連通する輸液セツトが挿入される。 In the present invention, the hanging device is usually provided at the center of the bottom of the container. The bottom of the container has a recess in the center and is designed to fit below the bottom surface when the hanging tool is laid down, and is designed to allow the container to stand on its own when the injection solution is injected into the container. Ru. The inlet/outlet has a structure that can be sealed with a stopper, and an infusion set communicating with the injection needle is inserted into the inlet/outlet.

長くなるものである。 The container body in the present invention has an oval cross section. This elliptical shape has a straight line portion in the major axis direction on its circumference, and the straight line portion becomes longer in the flattened oval of the intermediate body between the container shoulder and the bottom. Here, the flat ellipse refers to an ellipse in which the length of its minor axis is shorter, and therefore, as described above, the straight portion in the major axis direction is longer.

による作用により内容液の排出が円滑となる。 In addition, in the present invention, the length of the long axis of the oval shape of the body from the container shoulder to the container bottom is constant, and the side surface of the container is approximately straight from the container shoulder to the container body. This makes it extremely easy to handle the container during the production and management of the container itself, or the preservation and storage process, and the structure of the container body facilitates the discharge of the liquid content.

又、均一な排出速度が得られない。 Conventionally, this type of container has an elliptical cross-sectional shape, and in the case of an ellipse, the container wall surface parallel to the major axis of the container is convex (⌒). In the case of an elliptical shape, when the liquid inside the container is drained, the minor axis becomes shorter and the shape tries to become flat, but since the wall surface is convex, it is difficult to become flat, and therefore, the liquid level of the container Either the minor axis of the bottom of the container becomes shorter, or the wall surface of the container suddenly turns over when the content liquid is discharged. As a result, residual liquid remains at the top of the container, making it impossible to check the exact amount of remaining liquid.
Moreover, a uniform discharge rate cannot be obtained.

As explained above, the present invention is a synthetic resin injection container whose body has an oval cross-sectional shape, and the intermediate body between the container shoulder and the bottom has an oval cross-section. By making the body into a flat oval shape and by making the long axis of the oval shape of the body constant from the shoulder of the container to the bottom of the container, air can be replaced when co-injecting other injection solutions and discharging the contents. Since there is no need for a ventilation needle for the injection of drugs, the operation for co-injecting drugs is simple and hygienic since there is no contamination of the liquid contents. Since it collapses flat and does not create negative pressure inside the container, the liquid inside can be drained smoothly and the amount of remaining liquid can be accurately confirmed visually.
