A device for dispensing a product may include a receptacle including at least one elastically deformable wall configured to be deformed to vary an interior volume of the receptacle, and a flow reducer defining a length and at least one passage. The flow reducer may at least partially include an elastically deformable, compressible material. The at least one passage may be substantially closed at at least one portion of its length when the flow reducer is in a substantially closed, at rest position. The at least one passage may be configured to enlarge when the compressible material is at least partially compressed via the effect of pressure from the product when the interior volume of the receptacle is reduced, thereby enabling dispensing of at least a portion of the product via the at least one passage.
