Abstract
The present invention relates to a nozzle for dispensing a product, in particular a foaming product, contained in a pressurized container. The nozzle comprises three elements: an element (6) for fixation onto the container; a dispensing element (5); and a lateral element (7) for coupling the first two elements. The coupling element (7) has an elasticity such that its height varies between the operating position and the position of repose by a value equal to the sum of the distance between the upper edge of the emergent stem in the position of repose and the projection of the hole when the nozzle is in the position of repose, and the distance corresponding to the course of driving in of the emergent stem between its position of repose and the position of complete opening of the valve. The emergent stem of the valve, in the position of repose, is completely outside the hole.
