发明名称 A pressurised refill canister with an outlet valve
摘要 A pressurised refill canister (5, figure 5A) contains a composition including a propellant. The canister has an outlet valve (20) having a stem (6) biased to a closed position by a first resilient member. The stem 6 has a maximum outer diameter of greater than 3mm. At the outlet end of the stem, within a circle having a diameter of 1.5mm, there is a feature present, such as a pin 62. Also claimed is a combination of the canister and a device to be refilled. The device comprises a reservoir with a fill valve with a seat (48) to receive the stem. The valve is biased by a second resilient member (38) having a spring force which is less than that of the first into a position in which it closes the fill valve. The valve projects into the seat to such an extent that it displaces the fill valve element to open a vent flow path around the valve element and around the outside of the stem. Further pressure urging the device and canister together causes the stem to land in the seat and the refill outlet valve to open, creating a flow path into the reservoir.
