PROBLEM TO BE SOLVED: To facilitate replacement work of a container unit, to achieve reuse and to secure convenience of operation of a content delivering mechanism with fixed type output part by allowing a user to unconsciously set a specific inserting position when a cylindrical output part is inserted to the nasal cavity.SOLUTION: An operating part 9a can be operated to a direction of content delivering operation and to the opposite direction of container unit removing operation. When the operating part 9a is pressed to the left in Figure, a rotating operation member 9 is rotated and a forked part 9b pushes an annular collar part 2f of a cap member 2 upward with respect to a stem 4 and the content in a housing 2g is delivered upward. When the operating part 9a is pulled up to the right in Figure, the forked part 9b pushes down an annular upper face 2c of the cap member 2 so that the container unit that includes the stem 4 comes off from a cover case 7. The output part includes a cylindrical part having a content delivering hole 7g, and an annular step part 7h formed on an outer peripheral face and shaped to allow a close contact with a peripheral part of entrance of the nasal cavity when inserting to it.COPYRIGHT: (C)2013,JPO&INPIT【課題】出力部固定タイプの内容物放出機構に関し、容器ユニットの取替え作業の簡単化と、再利用化を図り、また、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】操作部9aを、内容物放出操作方向およびこれとは逆の容器ユニット取外し操作方向へ操作可能なものとした。操作部9aを図示左に押圧すると回動操作部材9が回動して、その二股部分9bがキャップ部材2の環鍔状部2fをステム4に対して押し上げ、ハウジング2gの内容物が上方に放出される。操作部9aを図示右に引き起こすと、二股部分9bがキャップ部材2の環状上面2cを押し下げて、ステム4を含む容器ユニットがカバー筐体7から外れる。また、出力部は、内容物放出孔7gを備えた筒状部からなり、鼻腔の中へ挿入されるときにその入口周辺部と当接するかたちの環状段部7hを外周面に備えている。【選択図】図1
