Claims (6)
- 包装容器に設けられるスパウトと、該スパウトを閉栓するキャップとからなり、
前記スパウトは、前記包装容器に設けられるスパウト本体と、該スパウト本体の上方に設けられた筒状体とを備え、前記スパウトの内部を軸方向に貫通する流通路が設けられ、
前記キャップは、平板状または環状の頂壁部と、該頂壁部の外周縁から下方に延びる周壁部と、前記頂壁部の下面から下方に延びる栓体部とを備え、
前記キャップにより前記スパウトが閉栓される際、前記スパウトの前記筒状体が前記キャップの前記周壁部と前記栓体部の間に挿入されるとともに、前記キャップの栓体部が前記スパウトの前記筒状体の前記流通路に挿入される注出具であって、
前記スパウトの前記筒状体は、前記キャップの前記周壁部により被覆される口部において、薄肉状に形成された上側の薄肉口部と、厚肉状に形成された下側の厚肉口部とを備え、
前記キャップの前記栓体部は、前記頂壁部から下方に延びる栓体周壁部と、該栓体周壁部に設けられた栓体底壁部とを備え、前記スパウトの前記筒状体の前記流通路に挿入された際、前記キャップの前記周壁部により被覆されている前記スパウトの口部の領域内に位置して、前記栓体底壁部が前記筒状体の前記厚肉口部の上部に当接することにより、前記筒状体の前記薄肉口部の前記流通路が前記栓体底壁部により閉塞されるとともに、前記筒状体の前記厚肉口部の前記流通路が前記栓体底壁部と前記厚肉口部に囲まれることを特徴とする注出具。 - 前記厚肉口部は、前記薄肉口部との境界部分において上側から下側にかけて次第に厚みが増すように外面および/または内面がテーパ状に形成されている請求項1に記載の注出具。
- 前記薄肉口部は、上側から下側にかけて次第に厚みが増すように外面および/または内面がテーパ状に形成されている請求項1または請求項2に記載の注出具。
- 前記栓体部は、前記頂壁部から下方に延びる筒状の栓体周壁部と、該栓体周壁部に設けられた栓体底壁部とを備え、該栓体底壁部が前記スパウトの前記厚肉口部の厚みと同一または該厚みより大きい厚みを有する請求項1から請求項3のいずれかに記載の注出具。
- 前記栓体底壁部は、下面または上面にバリア部材が展設されている請求項4に記載の注出具。
- 請求項1から請求項5のいずれかに記載の注出具が設けられていることを特徴とする包装容器。
