A fluid storage system includes a container defining an interior space that lacks an internal valve. A product and a propellant are stored under pressure within the interior space. A container cap includes a membrane that encloses a space defined by a coupling element, which includes a releasable fastener that releasably couples a fluid dispensing apparatus to the container. The container cap also includes a dip tube comprising a proximate end that extends at least partially into the space defined by the coupling element, and a distal end that protrudes from the space in a direction generally away from the container cap, into the interior space defined by the container. The dip tube defines an interior passage extending between the proximate end and the distal end through which the product is to be expelled from the container by the propellant.

A fluid dispensing apparatus may be used to dispense a fluid from a container that is under pressure and that has a pierceable membrane. The fluid dispensing apparatus may include a valve body having a bore, an adaptor having a bore and a piercing member, and a nozzle having a bore. The fluid dispensing apparatus may be operable to pierce the pierceable membrane to communicate the fluid within the container with the adaptor bore and with the valve body bore. The nozzle may be operable to permit the fluid to flow under the pressure out of the container, through the adaptor bore, through the valve body bore and through the nozzle bore to ambient.

An aerosol actuator has a main body member, a nozzle member defining an outlet opening, and a selector member. The outlet opening defines a fluid flow direction. The selector member is moved to obtain different fluid spray patterns. The selector member is distal to the nozzle member and the fluid flow direction.

A basket for securing a container to a dispenser has a device for connecting the basket with the dispenser and a device for connecting the basket with the container and a cylindrical seat for a valve of the container, wherein the basket provides a fluid connection between the container and the dispenser, wherein the basket provides a grip area for mounting the basket on the dispenser. The grip area is located on the cylindrical seat. The location of the grip area on the cylindrical seat reduces the height of the basket and improves the handling of the dispenser.

A portable, self-contained, hand-held, spray gun system having spray gun with a handle, barrel, trigger, and an interchangeable cartridge containing a sprayable substance which may flow from the cartridge under pressure through a portion of the barrel past a selectively positionable needle valve and out an exit orifice of a nozzle when the trigger is squeezed allowing a user to spray the pressurized contents of the vessel over a selected surface and stop such spraying activity by releasing the trigger all without the need for a separate power source or motorized compressor.

An adapter for a container includes a bracket having an annular sidewall and at least one projection extending interiorly from an external surface of the sidewall, wherein the at least one projection includes a sloped surface.

An attachment mechanism for a container includes a housing with a locking element extending therefrom. At least one opening extends through the locking element to selectively receive a portion of the container. A resilient member is disposed within the locking element.

A device for charging a primary fluid system, such as an air-conditioning or cooling system, closed and at a first pressure (P1), with a secondary fluid, comprises a dispensing cylinder of the secondary fluid, said cylinder containing the secondary fluid and a propellant fluid having a second pressure (P2) greater than said first pressure. Said cylinder further comprising a filler valve operable to allow/block the exit at least of the secondary fluid from the cylinder. A connection hood is partially superposed over the dispensing cylinder, fitted with connections means suitable for fluidically connecting said filler valve directly to said primary fluid system or to a connection pipe to said system.

A non-electrically powered automatic dosing and spraying valve assembly for a container of pressurized fluid with an outlet valve is described, wherein the valve assembly comprises a housing containing at least two chambers wherein one of those chambers is a main chamber open at one end to the contents of the container and closed at one end by a movable plunger, and another of those chambers is a dose chamber closed at one end by the movable plunger and closed at the other end by a prodder seal formed between a movable prodder and a fluid outlet opening; wherein the movable plunger is biased against movement toward the dose chamber by a main spring means and a prodder spring means, the main spring means being mounted in or adjacent to the dose chamber and the prodder spring means being connected to both the movable plunger and movable prodder, the assembly further comprises a fluid leak path between the main chamber and the dose chamber; and wherein the assembly is arranged such that, in use, one movable component of the assembly is configured to move relative to another component of the assembly to temporarily expose the dose chamber to the full fluid pressure of the main chamber.

Formulation and dispenser systems create dairy based toppings for beverages. The dispensers include a container, valve, and an actuator for the valve. The formulations include a liquid product and a propellant. The liquid product includes a certain percentage of milkfat provided, for example, by heavy cream, skim milk, nonfat dry milk, sweeteners, and an emulsifier. The propellant is nitrous oxide or nitrogen.
