Method and apparatus for measuring dispenser usage
First Claim
1. Apparatus for measuring the usage of a fluid dispenser which is actuated by pressure on an activating member which, in turn, triggers the discharge of material from the dispenser upon movement of the activating member from a starting position to a dispensing position and back to the starting position, comprising:
- a) a measuring apparatus attached to the dispenser and engagable by the activating member upon actuation thereof;
b) recording means carried by said measuring apparatus;
c) moveable actuating means carried by said measuring apparatus connected to said recording means; and
d) said recording means recording one cycle of use after the activating member and said moveable actuating means have returned to the starting position and then only after a predetermined lapse of time.

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.

7. A method of measuring the number of usages of a liquid dispenser in which a charge of material is emitted upon the movement of an activating member against a dispensing member comprising the steps of:
-
a) actuating a counter by movement of the activating member toward the dispensing member and engaging a moveable actuating means and returning the activating member to its starting position; and b) recording a dispensing event only after return of the activating member and the moveable actuating means to their starting position and then after a predetermined lapse of time. - View Dependent Claims (8)
