Tip for a foam-in-place dispenser

A foam-in-place dispenser through which foamable compositions are dispensed, said dispenser comprising:

• a housing having a discharge end;
• a valving rod disposed within said housing and being movable therein to control the flow of the foamable compositions through the dispenser;
• and
• a tip mounted at the discharge end of said housing and comprising:
• a body formed of a material that is porous to gases and liquids, but which is substantially impermeable to the foamable compositions that flow through the dispenser,
• a bore in said body that provides a channel through which the foamable compositions may flow and also through which an end portion of the valving rod can pass, and
• at least one face of said body forming a frusto-conical surface directed inwardly toward said body so that when a mixture of cleaning solvent and air is directed through said body, a frothing mixture of air and solvent will exit said frusto-conical surface to provide cleaning action to facilitate the removal of at least a portion of any foamable compositions or derivatives thereof that may be in adherence with said circular face or the end portion of the valving rod, said frusto-conical surface having a major diameter and a minor diameter, said tip further including an outermost rim coincident with or adjacent to said major diameter,
• wherein, the outermost rim of said tip extends beyond the discharge end of said housing to substantially confine the solvent, foamable composition and derivatives thereof to the porous, frusto-conical face of said tip.
