Abstract
A neck hole of a dispense tip is formed through a length of a body from an input end to an output end. An inlet hole is formed at a distal end of the neck hole, the inlet hole having a first inner diameter. An outlet hole is formed at a distal end of the inlet hole, the outlet hole having a second inner diameter less than the first. A first inner taper transitions the inlet hole from the first inner diameter to the second inner diameter. An outer taper is formed having a width that decreases along a longitudinal axis of the length of the neck hole at a distalmost end. The width of the outer taper is reduced at the distalmost end at the output end of the body of material from a first outer width to a second outer width less than the first outer width.
Claims8
A dispense tip for low-volume dispensing formed according to a process, comprising:
- forming a neck hole through a length of a body of material from an input end of the neck hole to an output end of the neck hole;
- forming an inlet hole at a distal end of the neck hole, the inlet hole having a first inner diameter;
- forming an outlet hole at a distal end of the inlet hole, the outlet hole having a second inner diameter less than the first inner diameter, a first inner taper transitioning the inlet hole from the first inner diameter to the second inner diameter;
- forming an outer taper having a width that decreases along a longitudinal axis of the length of the neck hole at a distalmost end of the outlet hole;
- and
- reducing the width of the outer taper at the distalmost end of the outlet hole at the output end of the body of material from a first outer width to a second outer width that is less than the first outer width.
