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.
Claims19
A method of forming a dispense tip that communicates with a material dispensing pump comprising:
- forming an elongated neck;
- micromolding a material to form a base having an outermost compressible surface;
- and
- coupling the base to the neck, wherein the base comprises an outermost region that includes a compressible fluid-tight surface that compliantly conforms to an outlet surface of the pump when the dispense tip is mounted to the pump.
A dispense tip that communicates with a material dispensing pump, the dispense tip comprising an elongated neck, a base, and a material path between an outermost region of the base and an outlet of the neck;
- the dispense tip formed according to the process of:
- molding a material having low viscosity to form a base;
- and
- coupling the base to the neck, wherein the outermost region of the base includes a compressible fluid-tight surface that compliantly conforms to an outlet surface of the pump 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 comprising stainless steel;
- and
- a base having a first portion and a second portion opposite the first portion, the first portion comprising stainless steel, the second portion comprising a compressible fluid-tight interface that compliantly conforms to an outlet surface of the material dispensing pump 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 comprising ceramics;
- a base having a compressible fluid-tight interface that compliantly conforms to an outlet surface of the material dispensing pump when the dispense tip is mounted to the pump;
- and
- a bonding material that bonds the neck to the base.
