Abstract

La présente invention concerne un récipient de pompe de type à levier de buse ayant une structure de levier. Ce récipient de pompe peut être utilisé de manière sélective soit dans un mode utilisant un bouton-poussoir soit dans un mode utilisant un levier de buse. Dans le cas du mode utilisant le levier de buse, un utilisateur peut presser le levier de buse à l'aide d'une seule main et recevoir simultanément un liquide à partir d'un orifice d'évacuation du levier de buse. Par conséquent, étant donné qu'une force importante peut être générée même avec une faible force en appliquant le principe des leviers, le récipient de pompe de type à levier de buse peut être utilisé avec une seule main et peut également être utilisé très facilement par les personnes âgées.
