Abstract:
1. A closure system for a dispenser, comprising: a neck of a container, comprising an annular neck wall extending around a longitudinal axis and defining an aperture for access to an inside of the container; an intermediate body, inserted on the neck; a body-neck coupling which fixes the intermediate body to the neck, allowing at most a limited, longitudinal movement, to prevent the intermediate body and the neck from separating; a frame of a dispenser head, which can be activated for aspiration of liquid from the container and dispensing the liquid to an outside environment; a releasable frame-body coupling, said frame being connected to the intermediate body by means of said frame-body coupling; wherein the intermediate body can be rotated on the neck by exerting a rotational action and the frame is detachably connected to the intermediate body, said frame-body coupling requiring for release a release action greater than the rotational action; and a body-neck interference mechanism which can interfere with the free rotation of the intermediate body on the neck of the container, wherein the body-neck interference mechanism comprises a body notching and a neck notching, engageable to each other so as to be fixed in rotation and yielding to move against each other by means of an action equal to or greater than the rotational action.
