Abstract: A manually operated dispensing device for a container holding a quantity of liquid is disclosed. The device has a variable volume pump chamber within a component retaining body. The chamber is defined by a bellows having a closed end or bottom, an open end or top, and corrugated sidewalls characterized by their resilience or elastic memory, and fabricated of any of the various thermoplastics. The bellows is associated with a movable member in the form of a trigger which when actuated compressively stresses the bellows in a direction significantly to reduce its length and the volume of the chamber therewithin. When the compression stress applied by the actuating member or trigger is relieved or removed, the bellows regains its original size and shape and returns the actuating member to its initial position.

Abstract: A manufacture of fluid handling devices having a variety of different surface contours or appearances features a universal fluid handling component retaining body and a shroud for enclosing the universal body, the shroud being a selected one of a variety of shrouds that are fabricated separately from the body and that are characterized by having a common internal surface configuration for engaging in permanently affixed, or removable relation, predetermined, selected exterior portions of the universal body, and further, that are characterized by having different external or surface contours or appearances, the latter being determined by merchandising or consumer preference.
