Dispensing head and unit for a product with a liquid-to-viscous consistency comprising a flow reducer, and method of manufacturing same
First Claim
1. A dispensing head for a product of a liquid-to-viscous consistency, comprising:
- a rigid cap having joined thereto an elastic flow-reducing element fitted with at least one slit provided with edges capable of moving away from one another under thrust of the product and of returning to an initial position when the thrust stops;
characterized in that, in the initial position, the edges of the slit are noncontiguous and are interspaced 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, thereby substantially reducing the thrust to be applied to cause the product to emerge;
further characterized in that the cap has a hinged lid with a seal having a protuberance in a shape complementary to that of the slit.

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.
