Fluid level measuring stick cleaning device (dip-squeeze)

摘要

A rectangular box with an opening at a small end contains a bent strip of flexible material around which is wrapped absorbment material. A fluid level measuring stick is inserted between these two end. A lever is pushed and brings the two ends of the flexible strip together. The stick is then removed, leaving its residue behind on the absorbment material. When the lever is released, the strip and lever resume their original position. The whole device is held in a fixed position by adhesive that is on the bottom of the box.
