Abstract:
The invention relates to a dispenser (20) comprising a dispenser container (90) filled with a dispensing carrier gas (140) fitted with a valve assembly (10). An ingredient (100) for dispensing is contained in an ingredient containing reservoir (110/150; 110/160), and the ingredient containing reservoir (110/150) is operatively connected to the dispenser container (90) and a dip tube (80) via first and second tubes (82; 84) such that on actuation of the valve assembly (10) the ingredient (100) and carrier dispensing gas (140) travel along the first tube (82) and the second tube (84) respectively, and mix in the valve assembly (10) before exiting the dispenser container (90) via the actuator spray nozzle (200). Alternatively the carrier dispensing gas (140) travels along the second tube (84) into the ingredient containing reservoir (110/160) and carries the ingredient (100) along the first tube (82) where they mix in the valve assembly (10) before exiting the dispenser container (90) via the actuator spray nozzle (200).
Abstract:
The invention provides a pressure control device for pressure packaging based on a disc with fluid connection and a collecting basin, with associated closing means. The closing mechanism in the pressure control device is no longer based on a cylinder with a central opening in the separation wall and closing-off of the opening by means of a piston with stem. The proposal is extremely simple, compact and easy to assemble. The use of O-rings is superfluous. The invention also relates to a method for manufacturing a pressure control system according to the invention and to a kit of parts for the assembly thereof.
Abstract:
A dual function aerosol valve assembly has a valve housing with first and second stem valves mounted for reciprocation within it. The first stem valve controls flow of gaseous propellant and the second stem valve is coaxially received within the first stem valve and controls flow of product. An actuator and nozzle assembly is connected with the stem valves so that the first stem valve is opened to admit propellant to the nozzle upon initial depression of the actuator, and the second stem valve is then opened to admit product to the nozzle. Closing of the stem valves is in reverse order so that flow of product to the nozzle is first interrupted and then flow of propellant is interrupted. A spring biases the stem valves to their closed positions. The valve housing is constructed to accommodate either a bag-on-valve system or a piston system.
Abstract:
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 comprising said 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.
Abstract:
A novel pressure control system is described, which is provided for maintaining a constant predetermined excess pressure in a fluid dispensing container (1; 32; 42), comprising a high-pressure plastic vessel (10; 30; 40) having an inner chamber, a closed end and an open end, and a pressure control device (18) with a valve, which pressure control device is mounted on the open end of the high- pressure vessel (10; 30; 40), whereas a passageway is provided from the inner chamber to the outside, which is controlled by the valve, wherein the high-pressure vessel (10; 30; 40) is essentially spherical.
Abstract:
The present invention relates to dispenser for producing a foam without requiring the use of liquefied gas, from an outlet. The dispenser (20) comprises a receptacle (37) for holding a surfactant solution (21), means for supplying a gas (23), means for conveying said surfactant solution in said receptacle and said gas along a flow path towards said outlet, wherein said conveying means comprises a conduit having a foaming section (25) for generating said foam from said surfactant solution (21) and said gas (23); and wherein said foaming section (25) has internal dimensions adapted to provide a foam having a quality characterised by predefined limits.
Abstract:
A dispensing system includes a decomposition chamber (132) having a catalyst (140) for the decomposition of hydrogen peroxide (H). The hydrogen peroxide and a foaming soap (F) are provided in separate first (114) and second (116) chambers of a product reservoir portion of a refill unit (110). Decomposition of the hydrogen peroxide produces oxygen gas and water, that may be used as a propellant for the creation of the foamed product, or may be used to power a pump. Additionally, the oxygen gas may be used to power a scavenger for the creation of electricity for charging a battery within the dispenser.
Abstract:
A novel pressure control device is provided comprising a first cylinder (3) at a predetermined excess pressure, a piston (4) with a sealing ring (5) being movable within said first cylinder, and a second cylinder (7). The first cylinder (3) is encompassed by the second cylinder (7) as to form a ring-shaped passage which is leading to the outside. A valve in said passageway is released and closed by a stem (14) of the piston (4). The open end of the first cylinder (3) is provided with at least one axially directed incision (37), such that the piston (4) with the sealing ring (5) introduced in the first cylinder (3) and covering the end of the incision (37) is in a non-pressurized position. The stem (14) has a stop element (15) which closes the valve in the upper position of the piston, wherein the piston stroke essentially defines the excess pressure.
Abstract:
The invention concerns a fluid product dispenser comprising a dispensing member (3) two reservoirs (1, 2) separated by a partition (21). The invention is characterised in that displacing means (33) are provided to move the dispensing member (3) towards the partition (21) to cause it to collapse, thereby enabling the contents of the two reservoirs to be mixed before being dispensed.
Abstract:
A pressurized beverage dispenser (100) having a beverage container (102) and a cap (101). The cap (101) includes a cap body (106), a compressed-gas cartridge (111), an external straw (108), a discharge chamber (135), a metering valve (137), a diaphragm (138), and an actuator (112). The discharge chamber (135) within the cap body (106) is in fluid communication with an internal passageway of the external straw (108). The metering valve (137) allows a flow of beverage from the beverage container (102) to the discharge chamber (135) when the metering valve (137) is open and substantially precludes the flow of beverage when the metering valve (137) is closed. The diaphragm (138) opens the metering valve (137) when the diaphragm (138) is activated and closes the metering valve (137) when the diaphragm (138) is deactivated. The diaphragm (138) also activates when a user sucks on the outlet end of the external straw (108) to create suction within the discharge chamber (135). The actuator (112) on the cap body (106) activates the diaphragm (138) when the user manually engages the actuator (112).
