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 dispense tip constructed and arranged to communicate with a material dispensing pump, the dispense tip comprising:
- an elongated neck;
- and
- a molded base, comprising:
- a first portion;
- a second portion extending from a distal end of the first portion and including a compressible fluid-tight surface that compliantly conforms to an outlet surface of the pump when the dispense tip is mounted to the pump;
- and
- a third portion extending from a proximal end of the first portion to provide rigidity and couple to the neck, wherein the neck extends from the third portion of the base.
A dispense tip constructed and arranged to communicate with a material dispensing pump, the dispense tip comprising:
- an elongated neck;
- and
- a molded base, comprising:
- a first portion;
- a second portion extending from a distal end of the first portion and including a compressible fluid-tight surface that compliantly conforms to an outlet surface of the pump when the dispense tip is mounted to the pump, the neck extending from the first portion of the base;
- and
- an inlet for receiving a source of fluid from the pump, wherein the first and second portions of the molded base are constructed and arranged to include a male Luer™ fitting at the inlet that communicates with an outlet of the pump.
A dispense tip that communicates with a material dispensing pump, the dispense tip formed according to the process of:
- molding a material having a low viscosity to form a base, the base comprising:
- a first portion;
- a second portion extending from a distal end of the first portion and including a compressible fluid-tight surface that compliantly conforms to an outlet surface of the pump when the dispense tip is mounted to the pump;
- and
- a third portion extending from a proximal end of the first portion to provide rigidity and couple to the neck so that the neck extends from the third portion of the base;
- forming the compressible fluid-tight surface of the second portion to have a flat outermost surface;
- and
- coupling an elongated neck to the third portion of the base.
