Abstract
A dispense tip constructed and arranged to communicate with a material dispensing pump comprises an elongated neck and a molded base having a first portion and a second portion opposite the first portion. The neck extends from the first portion of the base. The second portion is constructed and arranged to abut an outlet surface of the pump. An outermost region of the second portion of the base includes a compressible fluid-tight surface that compliantly conforms to the outlet surface when the dispense tip is mounted to the pump.

A method of forming a base of a material dispense tip, comprising:
- molding a polymer material to form a base including a proximal end having a low viscosity for coupling to an outlet surface of a material dispensing pump, including filling cavities or voids in the polymer material;
- and
- forming a funnel through the polymer material that delivers fluid from the material dispensing pump to a distal end of the molded polymer material, the funnel having a funnel inlet at an input end of the funnel and a funnel outlet at an output end of the funnel;
- and
- constructing and arranging the funnel outlet to align with and couple to an elongated neck such that the material dispense tip includes a single material path between the funnel outlet and an outlet at the distal end of the neck.
A method of forming a base of a material dispense tip, comprising:
- molding a polymer material to form a first portion of a base including a proximal end having a low viscosity for coupling to an outlet surface of a material dispensing pump, including filling cavities or voids in the polymer material;
- and
- forming a hole through the polymer material that delivers fluid from the material dispensing pump to the distal end of the molded polymer material, the hole having an inlet and an outlet;
- coupling the distal end of the molded polymer material to a second portion of the base, wherein the hole is aligned with a hole in the second portion of the base to form a single material path through the first and second portions of the base.
A material dispense tip formed according to a process comprising:
- molding a polymer material to form a base including a proximal end having a low viscosity for coupling to an outlet surface of a material dispensing pump, including filling cavities or voids in the polymer material;
- and
- forming a funnel through the polymer material that delivers fluid from the material dispensing pump to a distal end of the molded polymer material, the funnel having a funnel inlet at an input end of the funnel and a funnel outlet at an output end of the funnel;
- and
- constructing and arranging the funnel outlet to align with and couple to an elongated neck such that the material dispense tip includes a single material path between the funnel outlet and an outlet at the distal end of the neck.
