Abstract
A fluid dispenser includes a ring nut to be screwed on a bottle neck and including a shoulder and a collar extending in elevation from the shoulder. It also includes a dispensing head including a central portion, a spout designed to dispense the fluid contained in the bottle and a protective skirt extending to contain the collar of the ring nut. The protective skirt extends close to a peripheral portion of the shoulder and, in a closed configuration of the dispenser, has a safety distance from the shoulder. The dispensing head includes a cylindrical crown shaped to form a toothed profile and located between the protective skirt and the central portion. The ring nut collar includes gripping elements with a longitudinal extension and the toothed profile engages the gripping elements when closed. The toothed profile and the gripping elements are shaped to allow reciprocal rotation of the dispensing head.
