A nozzle for dispensing foam, comprising:
a foam generation housing (12) having a vent (36);
a mixing conduit (34) disposed in the foam generation housing (12) for blending fluid and vapor to generate foam, the mixing conduit (34) having an outlet and an inlet;
a plurality of spaced apart mesh screens (22,24) for creating turbulence zones disposed in the mixing conduit (34) adjacent to the outlet; and
a flared deformable vent seal for allowing the ingress of air into the container via the vent (36), the seal being disposed and movably engaged within the foam generation housing (12) for movement between an open position allowing air ingress and a closed position when foam is discharged. |
