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.
Claims18
A dispense tip constructed and arranged to communicate with a material dispensing pump, comprising:
- an elongated neck;
- and
- a molded base, the neck extending from the base, an outermost region of the base 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, wherein the compressible fluid-tight surface is at an interface region between the base and the pump to reduce or eliminate leaking of dispensing material from the interface region or leaching of solvents from the material during a dispensing operation that would otherwise occur.
A material dispensing system, comprising:
- a material dispensing pump comprising an inlet that receives a source of material and an outlet, wherein the material dispensing pump outputs the material from the inlet to the outlet;
- and
- a dispense tip compliantly conforming to a surface of the outlet of the material dispensing pump, the dispense tip comprising:
- an elongated neck;
- and
- a molded base, the neck extending from the base, an outermost region of the base 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, wherein the compressible fluid-tight surface is at an interface region between the base and the pump to reduce or eliminate leaking of dispensing material from the interface region or leaching of solvents from the material during a dispensing operation that would otherwise occur.
