Abstract
A hand-held spray pump includes a pump mechanism which may be pre-assembled and a pump housing which receives and encloses the pump mechanism. The pump mechanism includes a minimal number of inexpensive parts which are slidably assembled and snapped together. The housing includes a body portion and a cover portion with the body portion slidably receiving a trigger for operating the pump mechanism and for slidably receiving the pump mechanism. After the pump mechanism has been inserted into the body portion, the cover is snap-fitted over the pump mechanism. By utilizing the aforedescribed configuration, the pump housing may be readily changed without requiring changes in the configuration of the pump mechanism.
