Abstract
The finger actuated plunger of a dispenser has a protector cap pivotally mounted thereon and normally disposed for covering the discharge orifice. The cap is pivotally movable relative to the head upon application of finger force to the cap in the direction of plunger head reciprocation for uncovering the orifice. The cap is resiliently urged into its normal orifice-covering position upon removal of the applied finger force.
