Lockable actuating device for metering system of container containing medium e.g. body lotion cream, has inner circumferential surface that is spaced apart from outer circumferential surface to form cylindrical intermediate space

摘要

The device (1) has two mutually translational and rotational movable elements (2,3) that are arranged above container in vertical direction. The movable element (2) has a hollow cylindrical head section provided with a top surface (2c), an inner circumferential surface (2a) and an outer circumferential surface. The inner and outer circumferential surfaces are arranged concentrically with each other. The inner circumferential surface is spaced apart from outer circumferential surface in radial direction to form a cylindrical intermediate space in which an engagement ring is arranged.
