Abstract
Abstract A generally cylindrical cam track element with a plural stage cam track on a cylindrical face thereof is fixed upon the dispener''s head, and an inverted cup shaped overcap with a nodelike cam follower engages, by the latter, with a first stage of said cam track to hold the overcap on said element and, by rotation of the overcap during engagement of said follower in a later, frusto-spiraled stage of the cam track, a nozzle in the overcap seats upon and actuates the dispenser''s valve to discharge the dispenser''s contents through said nozzle. The cam track has an intermediate stage along which the follower must move differently from said first stage to said later stage. It is preferable that the cam track element have similar opposed cam tracks at opposite sides thereof and that the overcap be provided with two such followers to work therewithin.

Claim 1
Independent Claim
423 words
A cap assembly for a pressurized dispenser having a depressible valve that opens when axially depressed and closes when axially extended, said assembly consisting essentially of: 1. a generally cylindrical element fixable upon said pressurized dispenser coaxially to said valve, i. said element having a top wall with an opening therein aligned with said valve, 2. an overcap coactable with said element upon manipulation of said overcap to depress and thereby open said valve, said overcap including i. a top wall parallel to the top wall of the element, ii. a valve actuator integral with the top wall of the overcap, depending from said top wall in alignment with said valve, extending through the opening in the top wall of the element, having a discharge passageway therein for receiving and discharging emissions emanating from said valve when the valve is open, and including a counter bore at the valve facing end of the discharge passageway, iii. a skirt, iv. a radially inwardly extending node on the inner surface of said overcap, 3. means providing a cam track in the outer surface of the cylindrical element, said node being slidable in said cam track, said cam track having three portions providing a nodereceiving slot that runs continuously from a closed end of the first portion through the second portion to a closed end of the third portion, the second portion joining the remaining end of the first portion to the remaining end of the third portion, i. the first portion extending about said outer cylindrical surface of said element parallel to the top wall of the element, ii. the second portion extending away from said first portion in a direction perpendicular to the top wall of the element, iii. the third portion extending away from said second portion in a direction slanting downwardly from the top wall of said element, 4. said node being in stationary valve-inoperative position during rotation of the overcap with the node in the first portion, said node being in stationary valve-inoperative position during depression of the overcap with the node in the second portion, and said node being depressed during rotation of the overcap with the node in the third portion after leaving the second portion, said node reaching valve-operating position during movement of the third portion over the node between said remaining end of the third portion and the closed end of the third portion, 5. said element and said overcap having absent therefrom means biasing the same apart in a direction perpendicular to the top walls thereof.
