The invention relates to a distributor for a liquid product, in particular, a miniature spray, having a reduced number of parts. The distributor includes a reservoir and a manual action pump, provided with a hollow push-button, arranged such as to slide in a sealed manner with relation to the exterior of a tubular neck of the pump body, defining a dosing chamber, extending at least partly into the interior of the push-button.

What is claimed is: 1. A liquid product dispenser comprising a reservoir and a manually activated pump comprising a pump body mounted watertight in an opening of said reservoir and a tappet-button mounted in an extension of said pump body and mobile along the axial direction of the latter, characterized in that said tappet-button is hollow and mounted such as to slide in a watertight manner on the outside of a tubular neck of said pump body so as to delimit a dosage chamber extending at least partly inside said tappet-button and in that stopping means are disposed between an outer wall of said pump body and the inside of said tappet-button so as to define, under the stress from elastic means, a predetermined position, referred to as loose, of the tappet-button in relation to the pump body, and further characterized in that said tappet-button comprises two elements that fit axially into each other and in that the stopping means comprises segments connected to the end of a skirt of an inner element of the tappet-button and an annular shoulder or projection defined on the outer wall of said pump body, said segments being bent radially inwards when two elements of the tappet-button are fitted together, so as to create an overall annular stop that can cooperate with said annular shoulder or projection. 2. A dispenser according to claim 1, characterized in that each segment is connected to said skirt of the inner element by a thinner section made by moulding and forming a hinge. 3. A dispenser according to claim 2, characterized in that each segment has a triangular radial section. 4. A dispenser according to claim 3, characterized in that said segments are circumferentially adjacent and form a discontinuous crown on the end of said skirt. 5. A dispenser according to claim 4, characterized in that, in their non-stressed state, said segments extend radially outwards from the outer surface of said skirt, separated by cuts, according to a configuration that can be removed axially from its mould. 6. A dispenser according to claim 1, characterized in that the outer element of said tappet-button comprises an inner peripheral rib which forms a projection near a free end of this element and ensures the locking of the inner element fitted into the outer element after bending said segments. 7. A dispenser according to claim 1, characterized in that said inner element comprises an axial outlet conduit and in that outlet channels are disposed between the two elements and through an outer element of the tappet-button. 8. A dispenser according to claim 7, characterized in that said dispenser comprises a needle valve guided in axial translation in said pump body and extending in a space delimited between the pump body and the tappet-button, in that said needle valve cooperates with an inner orifice of said outlet conduit so as to define an outlet valve and in that said elastic means exert a stress on said needle valve and said tappet-button, pushing them axially away from the pump body. 9. A dispenser according to claim 8, characterized in that said needle valve extends beyond said tubular neck of the pump body and in that said needle valve comprises at least one lateral longitudinal channel that cooperates with the end of said tubular neck so as to define an inlet valve, the aforementioned dosage chamber being delimited between an inner wall of said inner element of the tappet-button, the wall of said needle valve and said open tubular section. 10. A dispenser according to claim 8, characterized in that said pump body comprises a guiding conduit in which said needle valve slides, in that said guiding conduit is provided with a bottom shoulder, in that said needle valve comprises a shoulder and in that the aforementioned elastic means are made up of a spring mounted with pre-compression between these two shoulders. 11. A liquid product dispenser comprising a reservoir and a manually activated pump comprising a pump body mounted watertight in an opening of said reservoir and a tappet-button mounted in an extension of said pump body and mobile along the axial direction of the latter, characterized in that said tappet-button is hollow and mounted such as to slide in a watertight manner on the outside of a tubular neck of said pump body so as to delimit a dosage chamber extending at least partly inside said tappet-button and in that stopping means are disposed between an outer wall of said pump body and the inside of said tappet-button so as to define, under the stress from elastic means, a predetermined position, referred to as loose, of the tappet-button in relation to the pump body, further characterized in that said tappet-button comprises two elements, an inner element and an outer element, that fit axially into each other, in that said inner element comprises an axial outlet conduit and in that outlet channels are disposed between the two elements and through said outer element, and further characterized in that said dispenser comprises a needle valve guided in axial translation in said pump body and extending in a space delimited between the pump body and the tappet-button, in that said needle valve cooperates with an inner orifice of said outlet conduit so as to define an outlet valve and in that said elastic means exert a stress on said needle valve and said tappet-button, pushing them axially away from the pump body. 12. A dispenser according to claim 11, characterized in that said needle valve extends beyond said tubular neck of the pump body and in that said needle valve comprises at least one lateral longitudinal channel that cooperates with the end of said tubular neck so as to define an inlet valve, the aforementioned dosage chamber being delimited between an inner wall of said inner element of the tappet-button, the wall of said needle valve and said open tubular section. 13. A dispenser according to claim 11, characterized in that said pump body comprises a guiding conduit in which said needle valve slides, in that said guiding conduit is provided with a bottom shoulder, in that said needle valve comprises a shoulder and in that the aforementioned elastic means are made up of a spring mounted with pre-compression between these two shoulders.
