Abstract:
1. A device for dispensing a fluid product, the device comprising: a reservoir configured to contain a fluid product and air, the reservoir defining an internal volume and comprising at least one deformable zone having a predetermined threshold resistance to deformation such that deformation of the at least one deformable zone does not depend linearly on pressure exerted thereon; a spray orifice; and a dip tube comprising wherein the deformable zone is configured to deform suddenly in response to pressure exerted on the deformable zone, thereby creating a sudden overpressure condition inside the reservoir so as to cause the product to be sprayed out from the orifice, and wherein the deformable zone is configured so that when pressure exerted on the deformable zone is less than a threshold pressure P
