A method of filling a hand held spray device is disclosed. The spray device includes a body having a reservoir. The method includes filling the reservoir with a first composition having a non-volatile silicone fluid, an antiperspirant active, an organoclay material, and at least one liquid activation enhancer having a Hansen Solubility Parameter for Hydrogen Bonding, .sub.h between about 2 and about 6 and a light transmittance value greater than 90%. The method further includes filling the reservoir with a liquid fragrance material after the reservoir is filled with the first composition to form an antiperspirant composition, attaching a valve to the body; and filling the reservoir with a propellant, wherein the hand held spray device has a propellant concentration after filling from about 30% to about 90% by weight of the total fill of materials within the reservoir and the non-volatile silicone fluid has a concentration from about 30% to about 70% by weight of the antiperspirant composition.

A system and corresponding method for charging an aerosol can with a compressed gas charge includes a base that is adapted for receiving a can that (i) houses a product and (ii) includes a means for injecting gas, such as a grommet or valve on the bottom of the container, and includes a compressed gas source, such as a pre-charged canister of compressed air, and air compressor, and/or an automatic or manual air pump. The can may be filled with at atmospheric pressure and then shipped while the can contains approximately atmospheric pressure. Upon receipt of the can, a user may charge the can with a compressed gas and repeat charging if needed after some of the product has been dispensed.

A unit for mixing and dispensing an aerosol precursor composition, and containers to be dispensed therefrom. The unit includes a plurality of bulk material filling stations, the plurality of bulk material filling stations have at least one first filling station with aerosol former and at least one second filling station with a flavor material for creating the aerosol precursor. The unit also includes a bulk consumable pack staging a plurality of containers configured to receive the aerosol precursor, and a robot configured to retrieve a container from the bulk consumable pack and move the container through at least two dimensions to stop at least two of the plurality of bulk material filling stations.

A machine and method for charging culinary cream whippers, by automatically injecting nitrous oxide, which makes it possible to optimise the charging time of culinary whippers and the availability of nitrous oxide for culinary whippers is disclosed, which has: a cabinet, wherein a first compartment is defined with its front portion open, at the base of which a nitrous oxide intake unit is arranged, external to this first compartment. The intake unit in the first compartment connects with a charging spout of the culinary whipper; inside the cabinet, in a second compartment, with a door, are provided at least one high-pressure nitrous oxide cylinder and the corresponding pneumatic, electric and electronic connections; and in the front of the machine is defined a control panel that makes it possible to operate the machine.

Method and device for controlling the quantity of liquid contained in a cartridge for an aerosol generating device, wherein the cartridge has a container and a liquid contained in the container and wherein, according to which is measured the quantity of liquid contained in the cartridge; and compared the quantity of liquid with a reference quantity of liquid.

A pressurized spray system is disclosed which includes a sealed container and an aqueous composition disposed inside the sealed container. The aqueous composition includes an amine solubilizer, and solubilized and gaseous carbon dioxide. Aerosol paint products and methods of making such systems and products are also disclosed.

Methods of making an aerosol container having an open neck at the top and a closed end bottom longitudinally spaced therefrom. The container has a valve cup and bag. The valve cup and bag are integral. The valve cup is attachable to the neck in sealing relationship. This arrangement provides for propellant to be disposed intermediate the container and bag. Product can be disposed in the bag for selective dispensing by a user actuated valve.

In the field of medical dosing device filling, a propellant conditioning assembly (10) comprises an input conduit (12) to receive a propellant at a constant pressure from a propellant reservoir (102). The conditioning assembly (10) also includes a bifurcation (18) to divide the input conduit (12) into first and second conditioning conduits (20, 22). The first conditioning conduit (20) includes a cooler device (24) to selectively cool a diverted first propellant stream (26) that flows through the first conditioning conduit (20), and the second conditioning conduit (22) includes a heater device (32) to selectively heat a diverted second propellant stream (34) that flows through the second conditioning conduit (22). The conditioning assembly (10) still further includes an output conduit (44) to receive the first and second propellant streams (26, 34). The relative proportion of the first and second propellant streams (26, 34) merging in the output conduit (44) is controlled to regulate the temperature of a merged constant pressure propellant feed (46) exiting from the output conduit (44).

An aerosol dispenser, outer container for an aerosol dispenser and a preform for an outer container, each include an open neck at the top and a closed end bottom. The open neck may include a first surface having a first surface diameter, a second surface disposed interior to the first surface and having a second surface diameter less than the first surface diameter, and a transition distinguishing the first surface from the second surface. For a dispenser and a container, a product delivery device may be disposed on the second surface and not interfere with a valve operable by a user when the valve is attached to the open neck in engagement with the first surface. At least one of the first and the second surfaces may be a sealing surface to prevent escape of propellant from the outer container to ambient when a valve is attached.
