ABSTRACT:
A one-piece molded body and housing unit for a pump dispenser, the housing comprising a pair of spaced side walls and a top wall. A vertical tubular support and pump cylinder are both spaced from the side walls and meet the top wall.

The mold includes blades on the upper mold half which extend down through the top wall to form the upper wall of the delivery tube. Additional blades on the upper mold half extend down through the top wall to form the channels and the trigger support pins in cooperation with mold surfaces from the lower half of the mold.
