(イ) 考案の目的
[産業上の利用分野]
この考案は輸液用容器等の内容物取出し口に取
付けられる栓体に関するものである。[Detailed description of the invention] (a) Purpose of the invention [Field of industrial application] This invention relates to a stopper that is attached to the contents outlet of an infusion container or the like.
[従来の技術]
輸液用容器から内容物である輸液を取出すとき
は、容器の底に位置する内容物取出口に取付けら
れた栓体に、中空の採液針を刺通し容器内外を連
通した状態で、この採液針が栓体から脱落しない
ように保つ必要がある。[Prior Art] When taking out the contents of an infusion solution from an infusion container, a hollow liquid collection needle is inserted through a stopper attached to a content outlet located at the bottom of the container to communicate the inside and outside of the container. It is necessary to keep this liquid collection needle from falling out of the stopper.
このため、栓体は、前記内容物取出口を密封す
る栓本体に、ゴムのような弾性材料からなり採液
針を刺通可能でかつ刺通した採液針を脱落しない
ように保持し得る弾性栓材を備えるように構成さ
れるのが一般的である。 For this reason, the stopper is made of an elastic material such as rubber and can be inserted into the stopper body that seals the content outlet, and is capable of holding the inserted liquid collection needle so that it does not fall out. It is generally constructed with an elastic plug material.
ここで、この弾性栓材は、採液針を刺通すると
きは内側へ押す力を受け、内容物取出し中は逆に
外側へ押す重力を受けるため、この双方の力に対
して栓体から脱落しないように構成する必要があ
る。 Here, this elastic plug material is subjected to a force that pushes it inward when the liquid collection needle is penetrated, and on the other hand, it is subjected to gravity that pushes it outward during the removal of the contents. It must be configured so that it does not fall off.
また、栓体は、使用前には、採液針を刺通する
面が外面に露出せずしかも、取扱い・開口操作が
容易であることが、望まれる。 In addition, it is desirable that the surface of the stopper through which the liquid collection needle is pierced is not exposed to the outside before use, and that it is easy to handle and open.
このような栓体としては従来より、例えば第9
図に示すような栓体101がある。 Conventionally, such a stopper has been used, for example, the 9th stopper.
There is a stopper 101 as shown in the figure.

る。 The first cylindrical body 103 and the second cylindrical body 106 cooperate to form a plug cylindrical portion 112 that forms a cylindrical outer peripheral wall,
A flow path 1 in the direction of the axis 113 is provided inside the stopper cylinder portion 112.
14 may be formed, but the flow path 114 is blocked by a thin film-like partition wall 115. The partition wall 115 is a part of the lower presser part 104.
It is molded integrally with the liquid sampling needle, and can be pierced with a liquid sampling needle, thereby forming a flow path 114.
下位栓体105と上位栓体108とは溶着部材
116によつて接合されている。すなわち溶着部

3 are integrally molded. The support piece 23 projects toward the center of the flow path 14 in a cantilever shape. The supporting piece 23 has a flat plate shape with a side surface 24 parallel to the shaft 13, and the lower end surface 25 of the supporting piece 23 is located below the position where the lower presser part 4 connects to the first cylindrical body 3. 3, the upper surface is flush with the presser surface 27, which is the upper surface of the lower presser part 4, and is a support surface that comes into contact with the lower surface 28 of the rubber plug body 11 together with the presser surface 27 and supports the rubber plug body 11. It has a total of 26.
The inner tip 31 of the support surface 26 is located inside the inner edge 32 of the presser surface 27, and the rubber stopper 11 falls off due to the force applied inward in the axial direction 13 of the liquid collection needle inserted into the rubber stopper 11. We can help you avoid this.
