An improved actuator (20) for actuating a container of a pressurized fluent product includes a body (56) having a dispensing flow path (76) to direct a pressurized fluent product from the container to an exterior of the actuator (20) via an exit orifice (80) located at an end of the flow path (76). The body (56) further includes a front exterior face (84) located adjacent to the exit orifice (64) and a hollow extension (88) defining a portion of the flow path (76) and extending along, and centered on, a longitudinal axis (92). The hollow extension (88) configured to retain an accumulation of the fluent product at the exit orifice (80) at a location that is spaced away from the front exterior face (84).

An article has a can with a valve stem and a dispensing device, the dispensing device includes a cap over the valve stem, a hollow tube extending through a slot in the cap and attached to the valve stem, a sleeve slidably extending over the hollow tube, a lever hingedly attached to the cap and operatively engaging the sleeve, an elastic feature that provides a force or causes a force to be applied to the sleeve in a direction that tries to move the sleeve to a closed position, and a sealing gasket between the sleeve and hollow tube proximate to the exit end of the hollow tube; where the sleeve seals the hollow tube when in the closed position and displacing the lever towards the can simultaneously unseals the hollow tube and tilts the valve stem, and when released allows the sleeve to restore to a closed position.

A device for dispensing a hydrofluoroolefin vapocoolant composition as an aerosol is disclosed. The device comprises an aerosol-dispensing container comprising an internal chamber, a valve, a dispensing hole, and an actuator. The device also comprises a hydrofluoroolefin vapocoolant composition comprising HCFO-1233zd at 70% to 100% (weight/weight) and, optionally, HFO-1234ze in at 0% to 30% (weight/weight). The hydrofluoroolefin vapocoolant composition is stored within the internal chamber. The aerosol-dispensing container is configured so that depressing the actuator reversibly opens the valve to allow the hydrofluoroolefin vapocoolant composition to flow from the internal chamber, past the valve, and through the dispensing hole, thereby dispensing the hydrofluoroolefin vapocoolant composition from the aerosol-dispensing container. A method of treating pain and/or swelling of a tissue of a patient by use of the device also is disclosed. The method comprises a step of dispensing the hydrofluoroolefin vapocoolant composition from the device onto the tissue of the patient.

A dispensing device for attaching to a container having a valve stem includes: (a) a hollow tube having a flow channel defined by a wall extending between entrance and exit ends with a connector on the entrance end for connecting to the valve stem; (b) a sleeve extending slidably over a portion of the hollow tube, the sleeve extending over, and having an opening proximate to, the hollow tube's exit end; (c) a sealing gasket around the outside of the hollow tube and between the hollow tube and the sleeve that prevents fluid communication past the gasket between the hollow tube and sleeve; (d) a trigger mount rigidly attached to the hollow tube or container; (e) a trigger hingedly connected at a first location to the trigger mount and operatively engaged with the sleeve at a second location; and (f) an elastic element between the trigger and the hollow tube and/or container.
