この実施例の合成樹脂製アンプル1mは、図17に示すように、アンプル本体2mと、アンプル本体2m内に収納された薬物6とを備える。 収納される薬物6としては、上述したものが用いられる。
筒状本体20mは、上部の内面形態を除き、上述した筒状本体20mと同じである。筒状本体20mは、下端開口を有し、上方に延びる中空部21と、中空部の上部に位置する先端部3mと、先端部3mの下部と中空部21の上部間、言い換えれば、先端部3mと中空部21の境界部を形成するように設けられた破断可能部5とを備える。中空部21は、薬物収納部53を備える。薬物収納部53の容積は、0.5~50ml程度であることが好ましい。中空部21は、図17に示すように、ほぼ同一外径および内径にて所定長延びる円筒部と、円筒部の上部に位置する内面テーパー部を備えている。
筒状本体20mの中空部(薬物収納部53)は、収納されている薬物が目視可能に透明に形成されていることが好ましい。また、筒状本体20mの薬物収納部53は、常圧でもよいが、減圧または真空状態としてもよい。このように、薬物収納部が減圧または真空状態であると、薬物の変質分解・劣化等の防止効果が向上する。
破断可能部5は、アンプル1にて説明したものと同じである。
軸方向のリブ57としては、幅が1μm~6mm程度のものが好ましく、高さが1μm~3.3mm程度のものが好ましい。
撥水性被膜は、中空部21の内面全体、さらには、後述する底面部4の上面を含むアンプル本体2mの内面全体に設けられていてもよい。撥水性被膜としては、アンプル1にて説明したものが好適に使用できる。
突起67としては、底面の外径が1μm~6mm程度のものが好ましく、高さが1μm~3.3mm程度のものが好ましい。
本合成樹脂製アンプル本体は、前述の通り、射出成型にて成形されるものであり、射出成形に適した硬質の各種樹脂材料を用いることが好ましい。
