Abstract
A child resistant manually actuated dispensing pump device includes a rotatable nozzle cap having a flange which defines a notch and an outer shroud having a tab which is dimensioned to engage the notch and lie substantially flush with or recessed relative to the flange so that it cannot be grasped and pulled out of the notch. When the tab is engaged in the notch, the nozzle cap cannot be rotated. The shroud is made of material which is flexible enough that it can be bent away from the nozzle cap, thereby lifting the tab out of the notch and permitting rotation of the cap. A second embodiment replaces the notch with a pair of ledges located on opposite sides of the nozzle cap, and provides a second tab on the opposite side of the shroud so that each tab engages a ledge.
