Abstract: The spraying can with preassembled dispenser valve includes a can body with which a dispenser valve is associated. An advantageous feature is constituted by the fact that the can body has, at its mouth, a cylindrical neck in which the dispenser valve is inserted; the valve has a cup-like body to which an upper cap is coupled; the cap defines, in cooperation with the cup-like body, a cavity in which a shutter, which protrudes from the upper cap, can move. The cylindrical neck is seamed onto a protruding ridge of the upper cap to sealingly couple the dispenser valve to the can body.

Abstract: A metering valve, wherein the cylindrical body or bowl which defines the liquid metering chamber in cooperation with the valve stem comprises a lower portion adapted for contact engagement with the valve stem such as to shut off the communication between the metering chamber and a container element, with the stem in a closure position, and an upper body associable with the lower portion and interchangeable to determine the useful volume of the metering chamber.
