|20140246506||SYSTEMS AND METHODS TO PRECISELY CONTROL OUTPUT PRESSURE IN BUFFERED SPRAYERS (DuO1) - Dispensing devices can include buffers. This obviates the need for continually pumping the device to dispense spray or foam. A buffer can be spring loaded, spring loaded combination, elastomeric or gas, and can be in line or adjacent to a piston chamber. Such sprayers and foamers can be mounted upside down. With a buffer, a piston chamber can deliver a greater amount of liquid per unit time than can be dispensed through the nozzle(s). The fraction of liquid that cannot be dispensed can be sent to the buffer for dispensing after the piston downstroke has completed. Volume of the piston chamber and buffer, pressure response of the buffer, throughput of the nozzle, and the minimum opening pressure of the outlet valve can be arranged to restrict the outlet pressures of liquid droplets exiting the nozzle within a defined range.||09-04-2014|

Using a unique valving system, where the product delivery circuit is a closed system, a Flair Sprayer can pump out any gas in a bottle's headspace and the product/liquid always reaches the pump intake, even with no dip tube. A dispensing device can have separate product and re-venting/propellant circuits, isolated one from the other, allowing for longer life and freshness of the product. Air or other displacement media can be used for various ancillary functions, all the while remaining isolated from the product, and the dispensing of the product can be adeptly controlled by pressure differentials (under-pressures and overpressures).||08-09-2012|
|20120187067||PREFORMS FOR FLAIR APPLICATIONS - A preform can be made from two different materials that do not bond together by a bi-injection process, using the same mold. An outer preform can be fashioned first, then an inner preform molded through a center hole in the outer preform's bottom. The preforms are then connected. Inner/outer preform materials can be different, e.g., PET/polyolefin or polyamide, or the same, e.g., PET/PET—if mutual bonding during the molding of the second is prevented. A non-stick coating can be sprayed on a surface portion of the first preform touching the second perform, then the second container molded. Manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the perform first molded, followed by molding of the other.||07-26-2012|
|20110210184||Device for mixing media and method for producing same ("aeroflair spray nozzle") - Various spray devices are presented for mixing two media. A device can include a housing, a first supply line for supplying a first medium, a second supply line for supplying a second medium, and a flow channel leading to a nozzle. The first and second media, for example, a gas and a liquid, respectively, can be mixed in various ways. Following such mixing, the mixed media are guided to an outlet nozzle or bore, and ejected. Using injection molding techniques, very fine grooves can be made in an exemplary spray nozzle device, by appropriately fashioning an injection mold. By carefully controlling the size, shape and dimensions of such grooves, and the pressures at which the two media are fed to the spray nozzle device, a correct ratio of air to liquid can be precisely maintained, which is key to obtaining a desired spray or foam as to droplet size, droplet speed, and type of spray, mist or foam.||09-01-2011|
|20110210141||Method and device for dosed dispensing of a liquid from a container ("Draught Flair") - Methods and systems for the dosed dispensing of a liquid from a container connected to an outflow channel closable by a liquid valve are presented. Such methods include opening the liquid valve, dispensing a measure of liquid from the container through the outflow channel, closing the liquid valve, and blowing out the outflow channel after closing the liquid valve. For example, during or after closing of the liquid valve the outflow channel can be connected to a gaseous source, the gas at a pressure greater than atmospheric pressure. Or, for example, where Flair™ technology is used, a limited quantity of a displacing gas can be guided to the outflow channel during or after closing of the liquid valve, or can be guided into an intermediate chamber connected to the outflow channel during or after closing of the liquid valve.||09-01-2011|

|20110024450||Composite container and method for manufacturing same ("Multi-Layer Preform") - A composite container, comprising a form-retaining outer container and a flexible inner container is presented. The inner container comprises a dispensing opening and can be mounted in a neck of the outer container, and the inner container is further connected to the outer container by an adhesive or weld connection over a portion of its periphery. The adhesive or weld connection can take the form of a ring adhesion or weld extending transversely to a central longitudinal axis of the container, or can cover the entire surface area of a defined portion of the respective inner container and outer container walls, such as, for example, the upper one-half of the container. The adhesion or weld can be substantially permanent, or alternatively, the adhesive or weld connection can be adapted to detach in controlled manner under the influence of pressures occurring in the container. Additionally, a method for manufacturing such a composite container is also presented, including forming a form-retaining outer container pre-form comprising a neck, forming a flexible inner container pre-form comprising a dispensing opening, inserting the inner container pre-form into the outer container pre-form and fixing said inner container pre-form to the neck of the outer-container pre-form. If the two containers are to be connected by adhesive, then prior to inserting the inner container pre-form into the outer container pre-form, a glue or adhesive can be applied either to the outer surface of the inner container pre-form or to the inner surface of the outer container pre-form, defining a portion of the surface area of the inner and outer containers where they will be connected. Once the two pre-forms are assembled, the composite container can be blown to full size under significant pressures, and the inner container becomes connected to the outer container over the defined portion of their periphery (e.g., their upper halves) by the adhesive spreading under such pressure, or by welding, into an air-tight seal. In exemplary embodiments of the present invention, the remaining portion of the inner container pre-form can be coated with an anti-stick coating prior to insertion into the outer container pre-form, so as to facilitate motion of the remaining portion of the flexible inner container relative to the outer container. In exemplary embodiments of the present invention, in operation, under pressure supplied by a displacing medium, the non-adhering portion of the inner container moves upwards within the outer container in a piston-like motion so as to dispense a product provided inside it, until it has completely folded on itself so that it its inner wall fully contacts the inner wall of the adhering portion of the inner container.||02-03-2011|
|20110017770||Method and apparatus for pressure equalized dispensing of a pressurized liquid in a container ("flair beverage valves") - A method for dosed dispensing of a pressurized liquid is presented. In exemplary embodiments of the present invention, the method includes dispensing a liquid in a container via a dispensing opening into a dispensing space, where a difference in pressure between the container and the dispensing space is equalized in stages by using an intermediate dosing chamber. In a first stage the pressure is equalized between the container and the dosing chamber, then a quantity of the liquid is dispensed from the container into the dosing chamber, maintaining the pressure equivalence between the container and the dosing chamber by pressure communication between them. Next, the dosing chamber is isolated both as to gaseous and liquid connection from the container. Then, in a second stage the pressure is equalized between the dosing chamber and the dispensing space, and the quantity of liquid in the dosing chamber is dispensed into the dispensing space as the pressure between the dosing chamber and the dispensing space is maintained equal. The method further includes providing the liquid in a first inner container of the container, and introducing a pressure equalizing medium into a second inner container, where the first and second inner containers adjoin each other at least with a deformable and/or displaceable side. The invention also relates to a dispensing device arranged to perform, inter alia, the disclosed method. In exemplary embodiments of the present invention a dispensing device can comprise a self-contained carbonated beverage dispenser that can be stored in a consumer's refrigerator, or can, for example, be self cooling.||01-27-2011|
