図1において1はポンプ機構を内蔵するボディである。このボディ1の上部には注出ノズル2と一体になるフランジ部1aが設けられており、このフランジ部1aに指をあてがい注出ノズル2とともに上下に移動させるか、あるいは容器を上下に移動させることによりポンプ機構を駆動する（ポンプ機構は図示せず）。 In FIG. 1, reference numeral 1 denotes a body incorporating a pump mechanism. At the top of the body 1 is provided a flange portion 1a that is integrated with the pouring nozzle 2, and a finger is applied to the flange portion 1a to move up and down with the pouring nozzle 2 or to move the container up and down. As a result, the pump mechanism is driven (the pump mechanism is not shown).
注出ノズル2は、テーパ状の先細り外観形状をなす本体部分2aを有するものであり、その先端には図2に符号を付して示した如く、外向きに開放された凹部2bが設けられている。 The dispensing nozzle 2 has a main body portion 2a having a tapered tapered appearance, and a concave portion 2b opened outward is provided at the tip thereof, as shown in FIG. ing.
また、3は泡生成ノズルチップである。この泡生成ノズルチップ3は、本体部分2aの凹部2bに、その底壁との間で若干の隙間t（隙間tは点鼻薬とエアとの混合室として機能する）を残して抜け出し不能に嵌合されており（凹部2bからの脱落を防止するため該ノズルチップ3の外側壁には、注出ノズル2の先端側へ向けてより突出代を大とするテーパ状の嵌め殺し突起dが設けられている）、該泡生成ノズルチップ3には、凹凸状の壁部eを持った経路3aと、ノズルチップ3の先端面に形成した外気導入口ｐからこのノズルチップ3の後端面にわたって貫通するエア導入経路3bがそれぞれ設けられている。 Reference numeral 3 denotes a bubble generation nozzle tip. This foam generating nozzle tip 3 is fitted in the recess 2b of the main body portion 2a so that it cannot be pulled out leaving a slight gap t between the bottom wall (the gap t functions as a mixing chamber for nasal spray and air). (To prevent the nozzle tip 3 from falling off the recess 2b, the outer wall of the nozzle tip 3 is provided with a taper-like projection d which has a larger protruding margin toward the tip side of the dispensing nozzle 2. The bubble generating nozzle tip 3 penetrates from the path 3a having the concavo-convex wall portion e to the rear end surface of the nozzle tip 3 from the outside air inlet p formed on the front end surface of the nozzle tip 3. Each air introduction path 3b is provided.
