| 20080272155 | Metering Valve and Device for Dispensing a Preferably Cosmetic Liquid - A metering valve ( | 11-06-2008 |
| 20090065533 | Dispensing apparatus - A dispensing apparatus comprising a dispensing container assembled with a metering valve. The dispensing container defines a storage volume for a product and the dispensing container comprises a neck terminating in an open top for receiving the metering valve. The open top extends radially outwardly relative to the neck to define a support surface. | 03-12-2009 |
| 20090145932 | METERING VALVE - A metering valve having a contiguous double wall structure including an inner wall defining the metering chamber and an outer wall which defines a crimping and support wall against which the inner rim of the mounting cup of the container can be crimped. The outer wall may be maintained at the same diameter and thickness for use with generally any mounting cup which are approximately an inch in diameter as well as any mounting process and machinery. The inner wall may however be sized differently in order to accommodate different dosages for metering of product. A radial space between the inner and outer wall permits the both the axial elongation of the metering chamber as well as a radial expansion of the inner wall and hence the valve chamber relative to the outer wall due to the space between the inner and outer wall. | 06-11-2009 |
| 20090188949 | FLUID OR POWDERY PRODUCT DISPENSER - A powder or liquid dispenser comprising:

| 20100051651 | METERING VALVE AND DISPENSING APPARATUS - A metering valve ( | 03-04-2010 |
| 20100327026 | VALVE - A fluid dispenser valve comprising a valve body ( | 12-30-2010 |
| 20110042419 | METERED DOSE VALVE - An aerosol metering valve comprising: (a) a valve stem movable between a rest position and a firing position comprising: a body portion comprising a circumferential sealing surface (b) a valve body comprising: a body wall, and an internal chamber defined at least in part by the body wall; and (c) a metering gasket having an inner periphery defining an aperture, being disposed near the most interior end of the internal chamber and being configured to be able to form a transient, substantially fluid-tight face seal against the circumferential sealing surface of the valve stem, where at the rest position of the valve stem, the body portion of the valve stem is located within the internal chamber and as the valve stem is moved from its rest position towards its firing position the circumferential sealing surface of the valve stem contacts the metering gasket to form a face seal thereby closing a metering chamber and thereafter further movement of the valve stem towards its firing position causes the metering gasket to deflect while maintaining the seal with the circumferential sealing surface of the valve stem; and wherein the metering gasket in an unbiased configuration is an annular disc having a substantially planar form and where the valve is constructed and arranged such that the inner periphery of the metering gasket is urged out of said substantially planar form at the rest position of the valve stem, or wherein the metering gasket is pre-biased into a dished-shape. | 02-24-2011 |
| 20110101037 | LIQUID DISPENSING APPARATUS - A discharge assembly for discharging a metered volume of a liquid held in a pressured container includes an elongate tubular housing, a valve stem having a body locating within the housing, a chamber provided within the body of the valve stem and having a liquid inlet, and a liquid discharge element moveable along the chamber from a liquid primed position to a liquid discharged position to effect discharge of the metered volume of liquid, wherein a second fluid transfer passageway is formed along the outside of the valve stem between the inlet of the housing and the first fluid transfer passageway, and a seal is provided for relative sliding movement onto a seat as the valve stem moves to close the second fluid transfer passageway to fluid flow. | 05-05-2011 |
| 20110108582 | LIQUID DISPENSING APPARATUS - A discharge assembly apparatus for discharging a metered volume of a liquid when used in combination with a liquid-containing, pressurised or pressurisable container includes an actuator assembly incorporating a valve stem having a discharge conduit arrangement with an inlet and an outlet, a metering chamber formed within the valve stem and incorporating a liquid discharge element, an inlet/outlet arrangement, and a housing wherein the valve stem and the inner surface of the housing define a fluid transfer passageway therebetween, the discharge conduit arrangement of the valve stem providing communication between the outlet of the metering chamber and the outlet of the valve stem via the fluid transfer passageway. | 05-12-2011 |
| 20120160878 | AEROSOL METERING VALVE AND DEVICE FOR DISPENSING A FLUID MATERIAL COMPRISING SUCH A VALVE - An aerosol metering valve ( | 06-28-2012 |
| 20120181306 | VALVE FOR DISPENSING A FLUID PRODUCT - A fluid dispenser valve for mounting on a neck of a reservoir containing fluid, the valve having a valve body including a metering chamber, and a valve member that is movable in the metering chamber between a rest position and a dispensing position. The metering chamber includes an upper gasket and a lower gasket that co-operate in leaktight manner with the valve member. The valve includes a neck gasket that co-operates in leaktight manner with the valve body and with the receptacle neck, the valve body being made as a single piece. The neck gasket and said lower gasket are overmolded on the single-piece valve body. | 07-19-2012 |
| 20130221035 | VALVE FOR DISPENSING A FLUID MATERIAL - A fluid dispenser valve for mounting on a neck ( | 08-29-2013 |
| 20140158719 | METERING VALVE - The present invention is directed to a metering valve used in both conventional and bag-on-valve aerosol container applications that allows a high flow rate of especially viscous substances. The metering valve according to the present invention including a valve housing, a valve stem, and a spring or other biasing device that allows the valve stem to move relative to the valve housing. The valve stem serves as a metering chamber with a metering device in the form of a ball or disk without other mechanisms such as springs or mechanical parts within the valve stem. Radial bores and a seal near the bottom of the valve stem provide for dispensing of pre-determined quantities of product from an aerosol container pressurized with liquefied propellants or compressed gas. The bore shape and size can be selected to facilitate a high volume flow rate for highly viscous substances. | 06-12-2014 |
