ABSTRACT:
An apparatus and method of counting dispensing events or washes in a fluid dispenser in which an activator is moved from a starting position to a dispensing position and back to dispense material includes a counter which is indexable to record a dispensing event only after dispensing pressure is totally relieved from the activator for a predetermined period of time. The counter is activated by a resilient member which is compressed by the activator but delays its full return to its starting state until compression is totally removed for the predetermined period of time. Only after elapse of this period of time is the counter activated.
