Abstract
A pump unit is adapted for attachment to a liquid container having a liquid discharge opening bounded by an annular rim formed with an external screw thread by providing the housing of the pump unit with an annular mounting flange and employing a two-part cap rotatably coupled to the mounting flange to threadably couple the pump unit to the screw thread of the container rim. The parts of the cap are hinge connected to allow for swinging movement of the parts between remote and adjacent positions as an incident to which the cap is coupled to the mounting flange and provided with a latch for retaining the parts in their adjacent position.
