ABSTRACT:
An improved spout assembly for a squeeze bottle or the like includes an extensible dispensing tube slidably disposed in an elongated, hollow cap member, with the distal end of the tube extending from an orifice at the tip of the cap member. The tube is extensible from the cap member to a selected extended position. The cap member has an improved structure which includes a plurality of discrete, spaced-apart, rib-like bearing elements extending radially inwardly from the interior wall surface of the cap near the tip. The bearing elements frictionally engage the extensible tube so as to maintain the tube in a selected position. The cap member is made of injection-molded plastic formed in a novel mold assembly comprising a solid core and a hollow cavity. The core has a cylindrical plug extending axially from its tip. The plug snugly seats in a socket at the bottom of the cavity. When molten plastic is injected into the gap between the core and the walls of the cavity, the cap is formed with an orifice created around the juncture between the plug and the socket.
