Abstract: An actuator overcap for producing multiple spray patterns includes a cap having a hub with a lower surface defining a socket and an upper surface defining a chamber fluidly communicating with the socket. First and second barrels extend between the hub and a side wall of the cap to define first and second flow paths. A trigger is pivotably coupled to the cap and includes a seal support. A selector is coupled to the trigger, and includes a user-engageable pad and a seal. The seal is configured to closely fit within the hub chamber and defines a central aperture fluidly communicating with the hub chamber and a first notch extending radially outwardly from and fluidly communicating with the central aperture. The trigger and selector are pivotable with respect to the cap to place the first notch in fluid communication with one of the first and second flow paths.

Abstract: This invention relates to a high alcohol content aerosol antimicrobial mousse which is dispensed as a foam for use as an antiseptic. The mousse composition comprises (1) 85-98% of an intermediate concentrate and (2) 2-15% of a hydrocarbon propellant. The intermediate concentrate comprises from 52-75% by weight of ethanol or isopropyl alcohol; from 0.1% to 1.5% by weight of a water-dispersible polymeric gelling agent; an amphiphilic system consisting of from 0.5% to 5.0% by weight of (a) at least one alcohol with a hydrocarbon group of from 16 to 22 carbons and (b) at least one nonionic surfactant, the hydrophilic balance (HLB) of the combination components "a" and "b" is in the range of 4.5 to 8.0 and the balance being at least 20 wt % of water. The hydrocarbon propellant is a saturated aliphatic hydrocarbon having from 2 to 6 carbon atoms.
