Abstract
A device for dispensing a fluid product includes a reservoir configured to contain a fluid product and air, a spray orifice associated with the reservoir, and a dip tube. The reservoir may include at least one deformable zone having a predetermined threshold resistance to deformation. The deformable zone may be configured to deform in response to pressure exerted on the deformable zone so as to cause the product to be sprayed out from the orifice. When pressure exerted on the deformable zone is less than a threshold pressure Ps sufficient to overcome the predetermined threshold resistance to deformation of the deformable zone, the internal volume of the reservoir is not substantially reduced.

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;
- a spray orifice;
- and
- a dip tube comprising
- a first end located adjacent a bottom of the reservoir, and
- a second end being in flow communication with the spray orifice,
- wherein the deformable zone is configured to deform in response to pressure exerted on the deformable zone 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 Ps sufficient to overcome the predetermined threshold resistance to deformation of the deformable zone, the internal volume of the reservoir is not substantially reduced.
