Abstract
A thermoplastic squeeze tube has a tubular member and attached rotatable closure cap, the tubular member closed by a diaphragm having a closure plug, at least one dispensing aperture, and plurality of ramps, and the closure cap having a top wall with a central dispensing orifice and plurality of closure cap ramps. On rotation of the closure cap, the closure cap ramps ride along the diaphragm ramps to force the diaphragm away from the cap top wall and open a flow path between the closure plug and top wall. Preferably a spout is provided on the closure cap so that the tube contents may be radially discharged and stop members are provided to limit rotation of the closure cap on the tubular member.
