  • the propellant is a liquefied gas, such as butane, propane, isobutane or mixtures thereof.
  • the liquefied gas typically forms a solution or emulsion with the other components of content 14 and is in equilibrium with propellant gas, which occupies a volume of the container (e.g., the "head space") and generates the internal pressure used to discharge the product from inside the container. Furthermore, the gas expands to form many "bubbles" within the composition thereby creating the foam.
  • Sufficient gas is contained in the container to substantially expel all the product from the container at the correct pressure throughout the life of the article. The quantity also depends from the type of gases used.

Sealer 30 and upper conduit 18 are positioned in vertical alignment of one another, so that sealer 30 can block or interrupt fluid communication between chamber 16 and upper conduit 18 when positioned against the lower opening 18a of the upper conduit 18, as illustrated in FTG. 4.
  • Movable partition 28 includes at least one aperture 32 that provides a passageway or conduit between an upper region 16b and a lower region 16c of chamber 16.
  • Aperture 32 facilitates movement of content 14 and gas 12 across or through movable partition 28 as the movable partition moves within chamber 16.
  • the movable partition includes at least one and preferably a plurality of apertures 32. In one or more embodiments, at least 2 apertures, or at least 4 apertures or at least 8 apertures are used. Aperture size and number will vary depending on dispensing conditions, such as for example, the content viscosity and canister pressure.
  • apertures 32 may be configured as a matrix of apertures or in a geometric configuration resembling that of a sieve.
  • Aperture 32 typically has a dimension inversely proportional to the pressure of gas 12 in container 10 and proportional to the viscosity of content 14.

In certain embodiments, aperture 32 may have a dimension substantially approximating 1% of the surface area of movable partition 28. In one or more embodiments, a plurality of movable partitions may be used, and may include a variety of apertures 32, depending on the viscosity of content 14 and the pressure of gas 12 in container 10.
  • a biasing element 34 optionally may be attached to or integrally formed with movable partition 28 in order to provide an additional opposing force on movable partition 28 as it is displaced substantially vertically in chamber 16.
  • Exemplary biasing means include springs that can be attached to a lower surface 28a of movable partition 28 or a weight (not shown) that can be attached to the upper (28a) or lower (28b) surface of the movable partition [others?]. Biasing means serves the additional purpose of keeping the movable partition in its rest position between dosing. This can be particularly helpful to avoid movement during handling.
  • the upper conduit 18 is in fluid communication with valve 26.
  • Lever 22 is disposed between upper conduit 18 and valve 26. By applying an external pressure to lever 22, the lever moves between a first (open) and second (closed) position. In the closed position, the passageway between conduit 18 and valve 26 is blocked and contents of container 10 are isolated from the exterior. In the open position, valve 26 is in fluid communication with the container interior and the contents of container 10 may be dispensed from the container through valve 26.

  • a shoulder 36 is attached to or integrally formed with chamber 16 and or upper conduit 18 such that a tapered seal is formed. A similar effect can be achieved by downwardly sloping the top surface of the chamber. In one or more embodiments, shoulder 36 contacts movable partition 28 and halts its upward movement before it reaches the end of the chamber. Shoulders 36 may provide spacing between the movable partition and chamber exit 18a, which may be desirable, for example, in providing an optimal seal between sealer 30 and upper conduit 18. Bias 34, e.g., a spring, which is fixed at both ends, e.g., on the lower surface 28a of the partition and on the floor 16d of the chamber, extends with the partition as it advances through the metering chamber.

  • a dipstick 86 is immersed in or in fluid communication with content 14, thereby readily facilitating flow of liquids, fluids and gas from the interior of the container 80. In order to deliver the majority of the content from the container, dipstick 86 extends a distance into the region of container where content 14 resides. In some embodiments, dipstick 86 extends substantially to a floor 80a of container 80. [0061] The upper opening of dipstick 86 is in fluid communication with valve 88. Lever 89 is disposed between dipstick 86 and valve 88.

In the closed position, the passageway between dipstick 86 and valve 88 is blocked arid contents of container 80 are isolated from the exterior. In the open position, valve 88 is in fluid communication with the container interior and the contents of container 80 may be dispensed from the container through valve 88.

Abstract

L'invention concerne un appareil et un procédé permettant de distribuer une quantité de contenu prédéterminée en provenance d'un réservoir sous pression. Cet appareil comprend un réservoir pour contenir un gaz sous pression et un contenu; une soupape permettant de libérer le contenu en provenance du réservoir; une chambre de dosage en communication fluidique avec le réservoir et la soupape et ayant une paroi supérieure et une paroi inférieure, la chambre de dosage définissant un volume proportionné à une quantité de contenu prédéterminée destinée à être distribuée; et une cloison mobile comprenant un joint d'étanchéité positionné dans la chambre et capable de se déplacer d'une première position de repos vers une seconde position de fermeture étanche, la position de fermeture étanche fermant de façon étanche la communication fluidique de la chambre avec la soupape. Lorsque la soupape est ouverte afin de distribuer le contenu en provenance du réservoir, la cloison mobile se déplace d'une première position de repos vers une seconde position de fermeture étanche.
