A module for dispensing a product intended to be mounted on a conduit (4) for pressurised supply of the product. The module has a path (2) for retrieving the product from a supply passage (5) which is intended to be in communication with the conduit to a passage (3) for discharging the product for the dispensing thereof. The retrieval path having at least one downstream conduit that opens into the discharge passage (3) and at least one upstream conduit that is in communication with the supply passage (5). The upstream and downstream conduits having a U-shaped junction that is designed to place the conduits in communication. At least one of the conduits being delimited by at least one wall that is capable of providing a microbiocidal action on the product contained in the conduit.

A device (1) for dispensing a fluid substance (S) having a cup-shaped body (3) equipped, at the bottom (2) thereof, with a first valve element (4) which intercepts a passage (5) for the suction of the fluid substance into a compression chamber (6), a closing element (7) equipped with a window (8), a dispensing button (15), and a shaped element (9) functionally coupled to the dispensing button (15) for the movement thereof into the cup-shaped body (3), the shaped element (9) including a flange portion (10) configured to slide along an internal wall (3A) of the cup-shaped body, a deformable portion (11) extending from the flange portion (10) which is bell-shaped when non-deformed, the deformable portion (11) being elastically deformable, the deformable portion (11) determining, at least together with a part of the cup-shaped body (3), the compression chamber (6).
