<p>A packaging and dispensing device comprises a container containing product to be dispensed under pressure, propellant, and retaining member(s); and a valve coupled the container and including a body having a first passage through which the product enters the valve body when valve is actuated, and a second passage through which the propellant enters the valve body when valve is actuated. A packaging and dispensing device comprises a container (10) containing a product (P) to be dispensed under pressure, a propellant (G) in the form of liquefied gas comprising gaseous and liquid phases, and retaining member(s) (60) partially trapping the liquid phase of propellant and having portion(s) that is permeable to gaseous phase of propellant; and a valve (20) coupled the container and including a body (21) having a first passage through which, when the device is in a first position, the product contained in the container enters the valve body when the valve is actuated, and a second passage through which, when the device is in the first position, the propellant contained in gaseous form enters the valve body when the valve is actuated.</p> |
