PROTECTOR CAP AND WIPER FOR DISPENSER DISCHARGE ORIFICE

摘要

A finger actuated plunger of a dispenser has a protector cap (27) telescoped over the plunger head (10) for reciprocation independently thereof along the axis of plunger reciprocation. A portion (31) 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 (32) adjacent such wall portion for alignment with the orifice for uncovering the orifice in a condition of use. A spring (35) extends solely between the head top wall (24) and the cap top wall (29) for resiliently urging the cap into its condition of non-use.
