The present disclosure is directed to methods and devices for reducing or otherwise mitigating accumulated reagent material and/or fluids within a dispense nozzle of a dispenser.
First claim
Opening claim text (preview).
The invention claimed is: 1. A nozzle cap comprising: a base and a retention member extending from the base; wherein the retention member has an inner surface, a first rim, and a second rim, the inner surface and first and second rims defining a lumen, the lumen extending from the first rim to the second rim, and wherein the nozzle cap further comprises a protuberance extending into the lumen; wherein the base further comprises a probe tool adapted for insertion into a bore of a dispense nozzle, wherein the probe tool comprises at least one abrading member. 2. The nozzle cap of claim 1 , wherein the probe tool has a shape which tapers from a first cross-sectional dimension to a second cross-sectional dimension, wherein the second cross-sectional dimension is greater than an inner diameter of the bore of the dispense nozzle. 3. The nozzle cap of claim 1 , wherein the at least one abrading member is positioned at a tip of the probe tool. 4. The nozzle cap of claim 1 , wherein the probe tool comprises an elongate member, and wherein the at least one abrading device is located along the length of the elongate member. 5. The nozzle cap of claim 1 , wherein a length of the probe tool extends beyond an outer edge of the base. 6. The nozzle cap of claim 1 , wherein the retention member is adapted to releasably engage the dispense member.
