PROTECTOR CAP AND WIPER FOR DISPENSER DISCHARGE ORIFICE |
摘要 |
A finger actuated plunger of a dispenser has a protector cap telescoped over the plunger head for reciprocation independently thereof along the axis of plunger reciprocation. A portion of the cap side wall covers the discharge orifice in the head in a condition of non-use, and the cap side wall has an aperture adjacent such wall portion for alignment with the orifice for uncovering the orifice in a condition of use. A spring extends solely between the head top wall and the cap top wall for resiliently urging the cap into its condition of non-use.
