Abstract: A frozen aerated product in a container, the container having a wall delimiting a cavity and having an opening, the cavity containing a bag, the opening being closed by a valve having a product inlet and a product outlet, the bag containing the product inlet, the cavity containing a propellant, the frozen aerated product being contained within the bag and gastightly separated from the propellant by the bag, there being an annular hermetic seal between the bag and the wall; characterised in that the bag is resiliently inflatable and the frozen aerated product is under a gauge pressure of between 4 and 18 bar.

Abstract: A frozen aerated product in a container is provided. The product is under a pressure of between 4 and 18 barg, and the container is provided with a valve. The valve has a flow rate of above 6 g s?1, preferably between 10 and 30 g s?1. The flow rate of the valve being the mass flow rate at which the frozen aerated product, having a temperature of ?18° C., is discharged through the fully open valve to atmospheric pressure. Also provided are valves suitable for dispensing viscous products at high flow rate whilst retaining a low opening and actuation force.
