Method for manufacturing a pressurising device for a beverage container, wherein a gas container is provided having a filling opening, into which gas container an amount of dry ice is inserted through the filling opening, where after the filling opening is closed and the dry ice is allowed to sublimate.

Provided with a discharge container that is easy to produce and maintains a constant discharge rate per unit time from the beginning to the end. This discharge container is provided with a bottle, a valve assembly configured to close an opening of the bottle and having a valve mechanism, and a pressure regulating mechanism accommodated in the bottle and configured to regulate the internal pressure of the bottle. The pressure regulating mechanism is attached to the lower end of the valve assembly.

A substance dispensing system including a first pressure vessel defining a first interior space; a first substance positioned in the first interior space; a first portion of a first propellant positioned in the first interior space; and a first portion of a second propellant positioned in the first interior space. At least 90 percent by weight of the first propellant is at least one of carbon dioxide, nitrous oxide, and combinations thereof. At least 90 percent by weight of the second propellant is at least one of nitrogen, argon, helium, oxygen, and combinations thereof.

The present invention provides a pressure control device for maintaining a constant predetermined pressure in a fluid dispensing container, as well as a pressure control system which includes the device. The present invention further concerns a method for manufacturing the pressure control device and system of the invention. The invention is of particular importance in the technical field of aerosol sprays.

A hand-held cosmetic dispenser having a housing with a first end and a second end, the housing having a nozzle coupled to a first end of the housing, a power source disposed within the housing, a spray button coupled to the housing, a cosmetic fluid compartment disposed within the housing and configured to receive and retain a fluid cosmetic, a gas compartment configured to receive and retain a gas cannister, and a gas controlling system disposed within the housing. The gas controlling system having a control mechanism that controls how much gas can leave the gas cannister. The power source is electrically coupled to the spray button and the gas controlling system. A method of using the same.

A spray applicator assembly discharges distributable product from a cartridge using low air pressure. The cartridge is held captive between a piston advancing from the rear to expel contents and a nozzle snugly attached at the front to receive expelled contents and to convert the contents into droplets by subjecting the contents to an array of focused high velocity air streams. The nozzle has an open barrel design and is able to discharge a variety of liquid or viscous distributable product without readjustment, other than resetting a proportioning valve in the low pressure air feed line. An air chamber immediately in front of the cartridge nose provides constant backpressure, which dominates to cleanly stop flow of distributable product into the nozzle whenever the piston stops advancing. When the piston resumes advancement, the flow restarts cleanly. Clean stopping and starting saves distributable product from waste. Variations in the distributable product might include, without limitation, a broad variety of materials including coating materials and combustibles.

A new method for fully automatically manufacturing a fluid container with a pressure unit is described, which pressure unit is mounted in a fluid container. In a station the high-pressure container of the pressure unit is mounted with the closure and the bottom part and is clamped at the upper and lower ends by clamping means and is rotated by rotating means associated with the clamping means. The rotating pressure unit is welded by first laser means and by second laser means, whereas the laser beam of the first laser means being directed to a first joint area of the bottom part of the pressure unit with the container, and the laser beam of the second laser means being directed to a second joint area of the bottom part of the pressure unit with the container, which first and second joint area are separated at a distance to each other

A pressure regulating system for a beverage container includes a first compartment for containing a pressurized gas. The first compartment is in fluid communication with a surrounding space through a gas valve for opening and closing a passage between the first compartment and surrounding space. A gas valve control system includes a deformable and/or movable wall or wall part, which is in contact with the gas valve for opening and/or closing the gas valve. A second compartment is provided at a side of the deformable and/or movable wall part. The movable and/or deformable wall part forms a wall of said second compartment and the second compartment forms a pressure regulating space and includes a wall part formed by or including at least a gas permeable, liquid tight permeable wall part.

A substance dispensing system including a first pressure vessel defining a first interior space; a first substance positioned in the first interior space; a first portion of a first propellant positioned in the first interior space; and a first portion of a second propellant positioned in the first interior space. At least 90 percent by weight of the first propellant is at least one of carbon dioxide, nitrous oxide, and combinations thereof. At least 90 percent by weight of the second propellant is at least one of nitrogen, argon, helium, oxygen, and combinations thereof.
