A device for packaging a product, particularly a cosmetic product, and for dispensing it under pressure includes a container which, at least in part, is translucent or transparent. The container delimits two compartments separated from one another in a sealed fashion. A first compartment is in communication with a valve fitted to the device, and contains the product to be dispensed under pressure. A second compartment contains a propellant in the form of a liquefied gas. A retainer is provided inside the second compartment and is capable of trapping the liquid phase of the propellant, the retainer having at least one portion which is permeable to the gaseous phase of the propellant.

1. A device for dispensing a product, comprising: a container having an interior including a first compartment and a second compartment separated from one another in a sealed manner, at least part of the container being one of translucent and transparent; a valve in communication with the first compartment; a product contained in the first compartment; a propellant present in the second compartment in a form of both a gaseous phase and a liquid phase; and a retainer provided in the second compartment, the liquid phase of the propellant being trapped in the retainer, and at least a portion of the retainer being permeable to the gaseous phase of the propellant. 2. The device according to claim 1, wherein the propellant is one of a butane, a propane, a chlorofluorocarbon (CFC), a fluorocarbon, and a dimethyl ether. 3. The device according to claim 1, further comprising a flexible-walled pouch defining the first compartment. 4. The device according to claim 3, wherein the pouch comprises a layer of a metal and at least one layer of a thermoplastic. 5. The device according to claim 4, wherein the metal comprises aluminum. 6. The device according to claim 4, wherein the thermoplastic comprises one of a polyamide, a polyethylene, and a polypropylene. 7. The device according to claim 1, further comprising a movable piston separating the first compartment from the second compartment. 8. The device according to claim 1, wherein the retainer is arranged in a bottom of the container. 9. The device according to claim 1, further comprising means for immobilizing the retainer inside the container. 10. The device according to claim 1, wherein the retainer is formed of one of a felt, a porous membrane located a distance from a bottom of the container, and a sintered element. 11. The device according to claim 1, wherein the retainer comprises one of a block of open-cell foam and a block of semi-open-cell foam. 12. The device according to claim 1, wherein the container comprises a thermoplastic material. 13. The device according to claim 12, wherein the thermoplastic material comprises one of a polyethylene terephthalate (PET), a polyethylene naphthalate (PEN), a polybutadiene (PBT), and a mixture of at least two of PET, PEN, and PBT. 14. The device according to claim 1, wherein the product contained in the first compartment includes a liquefied gas so that, when dispensed via the valve, the product forms one of a foam, a mousse, a milk, a gel, a cream, a care cream, and a spray. 15. The device according to claim 1, wherein the product is a cosmetic product. 16. The device according to claim 1, further comprising a stop configured to immobilize the retainer in the container. 17. The device according to claim 1, wherein the container includes at least one wall formed of at least one of translucent material and transparent material permitting a visual determination of the amount of the product in the first compartment. 18. The device according to claim 1, wherein the product is one of a shaving foam, a deodorant spray, and a hair care product. 19. The device according to claim 1, wherein the product is a hair care product chosen from one of a hairspray, a lacquer, a care cream, a gel, and a hair styling mousse. 20. A method of dispensing a product, comprising: providing the device of claim 1; actuating the valve to dispense product from the device; and directing the dispensed product to a surface region. 21. The method of claim 20, wherein the surface region is an external body portion. 22. The method of claim 20, wherein the product is one of a shaving foam, a deodorant spray, and a hair care product. 23. The method of claim 21, wherein the external body portion includes hair and wherein the product is a hair care product chosen from one of a hairspray, a lacquer, a care cream, a gel, and a hair styling mousse.
