AbstractAn expandable syringe comprising a bag having an opening through which liquid may pass. A closed end tubular valve stem projects outwardly from the bag opening and has an orifice in the side thereof in fluid communication with the interior of the bag. A nozzle has a female coupler sized to be movably mounted about the valve stem. The nozzle coupler has a valve seat against which the valve stem closed end may operationally engage in controlling the flow of liquid between the bag and nozzle. The bag may comprise a corrugated container or a shell having first and second openings and flexible pocket mounted to the shell sealing the first opening and sized for maneveur into and out of the shell through the first opening to displace liquid out of the shell. A nozzle or sprinkler cap may be detachably mounted to the shell over the second opening. Upon detachment of the nozzle or cap from the shell liquid may be introduced into the shell through the second opening thereby forcing the pocket to a position outside the shell. The nozzle or sprinkler cap may then be attached and the pocket squeezed into the shell thereby forcing the liquid out of the shell and nozzle. The sprinkler cap comprises a tubular member and an apertured sprinkler plate mounted therein having an elongated plate ledge. An articulated cover is joined to the tubular member at a joint aside the sprinkler plate. The cover has two sections hinged together along an elongated hinge parallel the plate ledge between the ledge and corner joint.
