Abstract: A dispenser device, including an outlet, air expeller including a piston that slides in an air chamber between rest position and dispensing positions, and a reservoir containing a dose composition. The reservoir includes an air inlet connected to the air expeller, and a composition outlet connected to the outlet, the air inlet including a composition retainer member, and the composition outlet being closed by a closure element force fitted in the composition outlet of the reservoir. A mechanical opening system co-operates with the closure element to expel it from its closed position while the device is actuated. The piston, when in its rest position, co-operates in non-airtight manner with the air chamber so that the air chamber communicates with the atmosphere. The piston includes an inner lip co-operating with a cylindrical surface, the cylindrical surface including fluting co-operating in non-airtight manner with the inner lip in the rest position.

Abstract translation: 包括出口的分配器装置，包括在静止位置和分配位置之间的空气室中滑动的活塞的空气推进器和包含剂量组合物的储存器。 储存器包括连接到空气排出器的空气入口和连接到出口的组合物出口，空气入口包括组合物保持构件，并且组合物出口由装配在储存器的组合物出口中的闭合元件力封闭。 机械打开系统与闭合元件配合，以在装置致动时将其从其关闭位置排出。 当处于其静止位置时，活塞与空气室非气密地协作，使得空气室与大气连通。 所述活塞包括与圆柱形表面配合的内唇缘，所述​​圆柱形表面包括与所述内唇缘处于静止位置非气密方式协作的凹槽。
