摘要: A spray confining aerosol dispensing device, includes a pressurized container provided with an upwardly directed axial nozzle on its top wall and valve actuator including pair of depressible opposite radial arms extending beyond the periphery. shield sleeve slidably engages is horizontally rotatable vertically movable between upper lower positions. peripherally spaced ribs are formed inside face above arm level when extended, so that may be rotated to bring in vertical registry arms. Depression pressed against surface sprayed, opens confined by sleeve. Stop members limit movement container.
