Abstract: A finger-operable pump cartridge is disposed within a closure for mounting the pump cartridge and closure to a container of fluent material. An actuator is mounted on the stem of the pump cartridge and has a skirt with a flange extending from, and continuously around, the skirt. A shroud is mounted around the closure and has a lip for engaging the actuator flange to inhibit removal of the actuator from the stem if the actuator is moved outwardly relative to the stem beyond a predetermined position. The actuator and closure may also include cooperating interengageable features accommodating rotation of the actuator relative to the closure between an actuatable position permitting reciprocation of the actuator and a releasably locked position preventing reciprocation of the actuator.

Abstract: A product discharge assembly is provided for a container of fluent material. A finger-operable pump cartridge is disposed within a closure for mounting the pump cartridge and closure to the container. An actuator is mounted on the pump cartridge. A shroud is mounted around the closure. The actuator has a skirt with a flange extending from, and continuously around, the skirt. The shroud has a lip for engaging the actuator flange to inhibit removal of the actuator from the stem if the actuator is moved outwardly relative to the stem beyond a predetermined position.
