The invention relates to a unit for dispensing a fluid product (10), comprising a body (11) and manually actuated dispensing means (20) which can be moved in said body (11) between a rest position and a dispensing position, said distribution means (20) being resiliently biased towards the rest position thereof by a resilient unit (100), said resilient unit (100) comprising a plurality of resilient cells (C) arranged in parallel about a longitudinal axis (X) of said resilient unit (100), forming a resilient level (N), and said resilient unit (100) comprises a plurality of resilience levels (..., N-1, N, N+1,...) vertically stacked along said longitudinal axis (X), characterized in that a resilience level (N) comprises an upper corrugated ring (110) having multiple corrugations and a lower corrugated ring (120) having multiple corrugations, arranged with respect to each other in such a manner that said upper and lower corrugated rings (110, 120) are in contact at several contact points (P) distributed about said longitudinal axis (X), a resilient cell (C) being defined between two contact points (P) adjacent to said resilience level (N), said resilient unit being produced, in particular by injection, from a synthetic material, such as polyoxymethylene (POM).
