Abstract
(EN)
A content injection operation button having an annular injection port according to the present invention facilitates uniform atomization of content, high deposition rate of content to an injection target such as an affected part, and silencing the sound of content injection. An injection port A is set between an annular nozzle 2 and a core 1c. A horizontally linear, content passage portion leading to the injection port A comprises an upstream-side annular lateral passage portion B that has a large content passage cross-sectional area between the upstream-side annular lateral passage portion and the core 1c and weakens the flow of the content, and a downstream-side annular lateral passage portion C provided on the downstream side of the upstream-side annular lateral passage portion B, the downstream-side annular lateral passage portion C having a shape where the content passage cross-sectional area continuously decreases in the direction of the flow of the content. How the content passage cross-sectional area of the downstream-side annular lateral passage portion C decreases is determined by an annular nozzle taper surface 2a whose inner diameter becomes small toward the injection port A, and the core 1c.

L'invention concerne un bouton d'opération d'injection de contenu doté d'un orifice d'injection annulaire qui facilite une atomisation de contenu uniforme, un taux de dépôt de contenu élevé sur une cible d'injection telle qu'une partie affectée et la suppression du son d'injection de contenu. Un orifice d'injection (A) est disposé entre une buse annulaire (2) et un noyau (1c). Une partie de passage de contenu linéaire horizontale menant à l'orifice d'injection (A) comprend une partie de passage latéral annulaire côté amont (B) qui comporte une grande surface de section transversale de passage de contenu entre la partie de passage latéral annulaire côté amont et le noyau (1c) et affaiblit le flux du contenu, et une partie de passage latéral annulaire côté aval (C) disposée sur le côté aval de la partie de passage latéral annulaire côté amont (B), la partie de passage latéral annulaire côté aval (C) ayant une forme dans laquelle la surface de section transversale de passage de contenu diminue en continu dans la direction du flux du contenu. La manière dont la surface de section transversale de passage de contenu de la partie de passage latéral annulaire côté aval (C) diminue est déterminée par une surface conique de buse annulaire (2a) dont le diamètre interne diminue en direction de l'orifice d'injection (A) et du noyau (1c).

環状の噴射口を備えた内容物噴射操作ボタンにおいて、内容物の均一な噴霧化、患部など噴射対象部への内容物の高付着率化や、内容物噴射時の消音化を図る。 環状ノズル2と中子1cとの間に噴射口Aが設定されている。この噴射口Aにいたる横方向直線状の内容物通路部は、中子1cとの間の内容物通過断面積が大きく内容物の流勢を弱める上流側環状横通路部Bと、その下流側で内容物通過断面積が内容物の流れ方向に連続的に縮小した形の下流側環状横通路部Cとからなっている。下流側環状横通路部Cの内容物通過断面積の縮小態様は、内径が噴射口Aに向けて小さくなる環状ノズルテーパ面2aと中子1cとによって設定される。
