Abstract
A leak proof package for fluid materials in which the end of a tubular nozzle from a container is closed by a wall and dispensing openings are formed in the side of the nozzle to extend radially. The dispensing openings are closed by a sleeve which initially is fixed to the wall. The sleeve is separated from the wall along a line of frangible webs by twisting the sleeve relative to the nozzle to fracture the webs after which the sleeve slides axially of the nozzle between positions opening or closing the dispensing openings in the nozzle.
