PROBLEM TO BE SOLVED: To provide a content releasing mechanism for nasal dropping, capable of securing convenience in operation by enabling a user to unconsciously set a predetermined inserting position in the case of inserting a tubular output part into a nasal cavity.SOLUTION: An annular step part 5h having a shape abutting on an inlet peripheral part of a nasal cavity when being inserted into the nasal cavity 9 is arranged in the outer peripheral surface of the output part 5d comprising a tubular part having a content releasing hole 5g. The user applies the annular step part 5h to the inlet part of the nasal cavity 9 and then pushes an operation part 6a in an (A) direction, thereby a turning operation part 6 turns, a bifurcated part 6b of the same push up the annular collar part 2e of a cap member 2 to a stem 4, and the content in a housing 2f is released in the nasal cavity 9 from a content releasing hole 5g through a content releasing path area and a content output path area 5e of the stem 4.COPYRIGHT: (C)2013,JPO&INPIT【課題】点鼻用内容物放出機構に関し、筒状出力部を鼻腔に入れる場合の挿入所定位置を利用者が無意識に設定可能にして、操作上の利便性を確保する。【解決手段】内容物放出孔5gを備えた筒状部からなる出力部5dの外周面に、鼻腔9の中へ挿入されるときに当該鼻腔の入口周辺部と当接するかたちの環状段部5hを設けた。利用者が環状段部5hを鼻腔9の入口部分に当ててから操作部6aをA方向に押圧すると回動操作部材6が回動して、その二股部分6bがキャップ部材2の環鍔状部2eをステム4に対して押し上げ、ハウジング2fの内容物がステム4の内容物放出通路域および内容物出力通路域5eを経て内容物放出孔5gから鼻腔9へ放出される。【選択図】図3
