The invention relates to a spray head () for a spray can with the spray head to be placed on a valve having an inner valve seat, wherein said spray head () being provided with a tubular hollow cylinder () extending coaxially to the longitudinal axis of the spray can, said cylinder being coupleable to the valve and designed to include a passage () for the spraying product contained in the spray can, said passage () ending in an outlet nozzle () pointing in radial direction and said hollow cylinder () having an opening () on one of its longitudinal sides at its valve-side end so that actuating the spray head () allows the product to be sprayed to enter the hollow cylinder () through said opening (), and wherein a rotatable regulating pin () extends through the passage () in the hollow cylinder (), the outer diameter of said regulating pin () corresponding at its valve-side end to the inside diameter of the passage () arranged in the hollow cylinder () and said regulating pin () having at its valve-side end on one of its longitudinal sides a cutout () that, when said cutout () coincides with the opening () in the hollow cylinder (), enables sprayed product to enter the passage (), with the regulating pin () at its end facing away from the valve being connected to a rotatable regulator () accessible from the outside. In this manner a spray head () is provided that enables the discharge rate to be varied and effectively avoids an uncontrolled discharge of sprayed product from spray head (). The invention is of special significance in the field of paint spray cans.

Variable spray head

The invention relates to a pressurized can comprising a body (), a dome () accommodating a valve (), a concavely shaped bottom (), an inner casing () attached to a cup () located in bottom (), a push rod () arranged in the inner casing (), said push rod () being actuated through the cup () and intended to force open the inner casing (), with said inner casing () being joined to the cup () via a spring cage (), said spring cage () containing a spring-loaded trigger () the bottom-side end of which extending through the cup () and acting on the push rod (), said push rod () acting on a membrane () arranged at the valve-side end of inner casing (), said membrane at its valve-side end sealing off the inner casing () hermetically against the contents of the pressurized can () and being forced open by the push rod () actuated by means of trigger element (), with the spring cage () being designed so as to be closed off at its valve side and the trigger element () being provided at its bottom side with a sealing element () acting against the inner wall of the spring cage.
