| 摘要 |
The invention relates to dispensing adapters for fluid products, from the channel of which a miniaturised valve 7, 8 blocks the emission orifice, giving way during functioning under the effect of the driving pressure used. This valve will preferably be in the form of a circular cupola 7a with its concaveness facing downstream and inserted, at the outlet of the channel 2, in a circular chamber formed upstream of the dispensing nozzle. On packages generally intended for ambulatory use, in particular the spraying of aerosols and particularly of medicines, it prevents the oozing of liquid in the rest state. <IMAGE>
