Abstract[English]
In some embodiments, a system for dispensing a fluid includes a dispensing plug and a squeezable container for receiving the dispensing plug and storing the fluid. The dispensing plug includes a one-way valve for dispensing the fluid. The squeezable container includes a squeezable wall, an opening for dispensing the fluid that is sealed airtight by the dispensing plug, an air-return hole in the squeezable wall, and an air-return valve that is permeable to air and impermeable to the fluid and that closes the air-return hole. The fluid leaves the squeezable container through the one-way valve of the dispensing plug in response to exerting a pressure onto the squeezable wall, and air enters the squeezable container through the air-return valve upon expansion of the squeezable wall in response to releasing the pressure onto the squeezable wall.[French]
Dans certains modes de réalisation de l'invention, un système de distribution d'un fluide comprend un bouchon de distribution et un récipient compressible destiné à recevoir le bouchon de distribution et à stocker le fluide. Le bouchon de distribution comprend une valve unidirectionnelle pour distribuer le fluide. Le récipient compressible comprend une paroi compressible, une ouverture de distribution de fluide scellée de manière étanche à l'air par le bouchon de distribution, un orifice de retour d'air dans la paroi compressible, et une valve de retour d'air perméable à l'air et imperméable au fluide et qui ferme l'orifice de retour d'air. Le fluide sort du récipient compressible par la valve unidirectionnelle du bouchon de distribution lorsqu'une pression est exercée sur la paroi compressible, et l'air pénètre dans le récipient compressible par la valve de retour d'air lorsque la paroi compressible se dilate après que la pression exercée sur celle-ci a été relâchée.
