A fuel canister valve assembly has a valve cup, a valve stem housing connected with the valve cup and defining a seal housing containing a valve seal and a valve stem having an inner end housed in the valve stem housing and extending through the valve seal to an outer end disposed externally of the valve stem housing. The valve stem housing has an outer periphery provided with at least one side passage defining a flow path along the outer periphery.

Disclosed is a system to generate bubbles. The bubbles may be formed to include a substantially or medically pure gas. The bubbles may be formed on demand and in a selected small size.

A liquid spray dispensing system has a liquid container receivable within a housing, provided in separable housing portions. The liquid container has at least one flexible side or end wall or a slidable end wall, movable by an actuator, to reduce the volume of a liquid storage compartment containing the liquid to be dispensed through a spray nozzle unit operably connected to the liquid storage compartment. By operating the spray nozzle unit, or a switch operably connected to a spray actuator of the spray nozzle unit, the actuator moves the flexible or slidable wall to reduce the volume of the liquid storage compartment, and thereby cause the pressurized liquid to be dispensed through the spray nozzle unit.

A pressurized container usable for a pressurizable contain, such as an aerosol dispenser, an aerosol dispenser made therewith and preform therefor. The preform/container/dispenser has a neck at the top. The neck has upper and lower portions. The lower portion transitions into a shoulder, which flares outwardly. The shoulder, in turn, transitions into a sidewall. The lower neck portion/shoulder and/or upper part of the sidewall are cystallized. The invention also comprises a preform for making such a pressurizable container and an aerosol dispenser made therewith.

A valve assembly for a pressurized container includes a valve stem and a mechanical seal. The valve stem has an open top portion, a closed bottom portion, at least one primary radial opening, at least one secondary radial opening and a valve stem passageway between the open top portion and both the at least one primary radial opening and the at least one secondary radial opening. The mechanical seal comprises a longitudinal passageway that seals the at least one primary radial opening and the at least one secondary radial opening, respectively, when the valve stem is in a closed position. Longitudinal translation of the valve stem exposes the at least one primary radial opening or both the at least one primary radial opening and the at least one secondary radial opening to the pressurized container when the valve stem is in an open position.

A discharge device is provided with a pressurized product filling and sealing the concentrate and the pressurizing agent P inside the container, and a discharge member discharging the concentrate by breaking through the pressurized product. The discharge member is provided with a valve which becomes a discharge passage of the concentrate, and a cap which covers the valve and is detachably mounted to the pressurized product. The discharge device is provided with a suppressing means (a maintaining mechanism, a movable lid, pressing to the bottom of the recessed part of the projecting part, a part releasing mechanism, a ratchet mechanism, a thin part and a plurality of coupling parts) for suppressing the leakage of the concentrate caused by removing the valve.
