Abstract
A timing apparatus on a container cap which is associated with a standard push pump. The timer is activated by pushing down on the standard pump that then moves a fluid that is held within a chamber having a first compartment and a second compartment. The compartments are in fluid communication with each other. The fluid is moved from one compartment to the other compartment when the pump is pushed and the timer works because the fluid returns to the first compartment over some known range of time when the pump is no longer being pushed.
