Abstract
A disposable spray applicator for liquid or pulverulent medicaments includes a receptacle containing the medicament and having one or more dosing chambers and is provided with a piston plug at one end, and a spray head with corresponding cap at the other end. The spray head surrounds the rim of the receptacle and is held in place by an annular sealing torus. The spray head is provided with a rectangular outlet canal, through which the medicament is sprayed at a right angle into a turbulence chamber formed by a spraying nozzle, and from there to the outside. The sealing torus has an annular groove on the surface of the receptacle facing the spray head, and an annular bead on the opposite, i.e. interior, surface. The bead mates with a correspondong groove on the piston plug to stop the action of the spray applicator when the plug has moved a distance corresponding to a measured dosage.
