Patent ID: 8690084

Claim:
A dispense tip comprising: a Luer™-type machined base for mounting the dispense tip to a dispensing device having a material pump that introduces a flow of material to the dispense tip during a dispensing operation, the base including a Luer™-type female coupling for mounting the dispense tip to a male coupling of the material pump, the base further including a funnel having a funnel inlet at an input end of the base constructed and arranged to receive the flow of material from the material pump and a funnel outlet at an output end of the funnel, the funnel having a smooth tapered inner surface that continuously narrows in diameter in a direction from the funnel inlet to the funnel outlet; an elongated machined neck, wherein the base and the neck are formed along a longitudinal axis from a single common stock of steel; a bore machined in the base and neck, the bore centered along the longitudinal axis, wherein an input end of the bore communicates with the funnel outlet; an opening at an output end of the neck, the opening at the output end of the neck being at an outermost end of the dispense tip, the opening adjacent to, and in communication with, an output end of the bore such that a single fluid path is formed between the funnel inlet and the opening; wherein: the input end of the bore comprises an inner surface of a first inner diameter, the output end of the bore comprises an inner surface of a second inner diameter, and the opening is of the second inner diameter, the first inner diameter being greater than the second inner diameter; wherein: an inner taper is machined in the bore of the neck for transitioning the inner surface of the bore from the first inner diameter to the second inner diameter, the bore being unobstructed both within the first inner diameter and the second inner diameter between the input end of the bore and the opening; and wherein: a portion of an outer surface of the base has a constant diameter, the portion extending in a direction along the longitudinal axis, the portion of the outer surface of the base being positioned between the Luer™-type female coupling and the funnel.
