Abstract: This disclosure relates to a dispensing head for a fluid product, comprising: a manually operable pusher, the pusher being configured to move between a high position (PH) and a low position (PB), and a nozzle for dispensing the fluid product made of a resilient material. The dispensing head is configured so that, during the movement of the pusher between the high position (PH) and the low position (PB), the nozzle passes from a closed position in which the nozzle is sealed, to an open position allowing the dispensing of the fluid product by deformation of the nozzle under the effect of a stress exerted by the support and/or a release of a stress exerted by the pusher.

Abstract: A pump having a piston (1) sliding in a body (3) having a chamber (5) between an inlet valve (11) and an outlet valve (12), an outlet valve element sliding during actuation in the chamber (5), and a passage (40) wherein, at end of actuation, the outlet valve element (39) cooperates in a non-sealing manner with the passage to open the outlet valve. The inlet valve has an inlet valve element (10) that slides after closure in a sleeve (9) with reduced diameter and a spring (20) bearing on the inlet valve element and on a bottom of the sleeve. The spring (20) returns the piston into its rest position. The sleeve (9) has an inner diameter of less than 4.2 mm. The spring (20) has a force of at least 20 N, so that the pump delivers the fluid product at a pressure (P) of at least 15 bars.
