Abstract
The invention relates to a dispensing head for a product of a liquid to viscous consistency, as well as a dispensing unit fitted on this head. This head has a rigid cap capable of being fixed on a reservoir for the product. An elastic flow reducing element is joined to the cap and is fitted with at least one slit provided with edges capable of moving away from one another under the thrust of the product and of returning to an initial position when the thrust stops. In the initial position, the edges of the slit are noncontiguous and are spaced from one another at a predetermined distance so as to define an opening through which the product cannot flow to any appreciable extent by gravity, substantially reducing the thrust to be applied for causing the product to emerge.
