Definitions

  • the present invention relates to improvements in metered dose valves for an aerosol and, specifically but not exclusively, metered dose valves Tor use with homecare aerosol products and devices.
  • Aerosols are well known as are metered dose valves for aerosols.
  • An aerosol spray is generally a can or a bottle containing a fluid, typically a liquid, under pressure, when the valve is opened the fluid is forced out and emerges therefrom as a mist
  • the fluid is generally provided with a propellent which evaporates inside the can to maintain an even pressure and, outside the can, assist with the mechanical break up of the fluid by evaporating rapidly.
  • a metered dose aerosol has a chamber located therein with seals located therein to only permit a pre-determined dose of fluid to be sprayed therefrom every time the valve is opened.
  • a drawback shared with both of these known aerosols is that they generally require a downward pressure to be applied to a valve in order to open it and spray the fluid.
  • an aerosol with a metered dose tat valve wherein the aerosol comprises:
  • valve housing with an inlet and an outlet
  • valve stem with an inlet and an outlet
  • valve stem outlet being substantially distal from the reservoir and outside the valve housing, and a sealing means at the other end of the stem inside the housing;
  • valve housing being provided with an internal volume corresponding to the dose of fluid to be sprayed, the housing being further provided with guide means to restrict the directional movement of the valve stem between a first position when the sealing means does not close the valve housing inlet and a second position where the valve stem has been tilted and the sealing means positioned in sealing engagement with the valve housing inlet to close the fluid pathway between said reservoir and said valve housing;
  • valve stem inlet is sealed closed against a resilient grommet in the first position and which is spaced from said grommet in the second position.
  • the guide means only permit movement in a single substantially lateral and linear direction of the outlet stem.
  • the guide means only permit the movement in two linear directions, said directions being substantia ⁇ perpendicular with respect to each other.
  • the guide means preferably protrude into the interior of the valve housing to define a channel and the sealing means of the stem substantially fill said channel.
  • valve housing has a Curved lower section adjacent the valve housing inlet
  • sealing means of the valve stem Is preferably correspondingly curved to advantageously provide for a dose sealing of said valve housing inlet in the second position and also an improved and easy to manoeuvre tilting operation of the valve stem in use between said first and second positions.
  • valve housing in made integral with and is connected to a lid of the aerosol body to permit easy attachment erf ftie to me rest ed by crimping or wielding or such like.
  • a metered dose tilt valve wherein the valve comprises:
  • valve housing with an inlet and an outlet
  • valve stem with an inlet and an outlet
  • valve stem has an opening at the end outside of the valve housing, and a seeling means at the other end of the stem inside said housing;
  • valve housing being provided with an internal volume corresponding to a predefined volume
  • the housing being further provided with guide means to restrict the directional movement of the valve stem from a first position when the sealing means does not close the valve housing inlet and the valve stem inlet is sealed closed against the resilient grommet, and a second position where tilting of the valve stem moves the sealing means into sealing engagement to close the valve housing inlet and which opens the valve stem fluid inlet by moving the stem and its fluid inlet away from the grommet.

  • the valve consists of a valve housing 10 having an internal dimension of a pre-defined volume to correspond to the volume of fluid, the dose, to be spayed in use of the aerosol.
  • the housing 10 has an inlet 14 and an outlet 16 sealed with a resilient grornmet 18.
  • the housing 10 retains a valve stem 12 partially therein, the stem 12 having an annular ridge 20 which forms a sealing engagement with the grornmet 18.
  • the valve stem 12 has a sealing means 22 formed by the shape of the end of the stem remote from a valve stem outlet 24.
  • the seeling means is curved to correspond to the curved shape of the valve housing adjacent the valve housing inlet 14.
  • a reservoir (not shown) is connected to the housing inlet 14 via diptube 26 to form a fluid pathway therebetween.
  • the sealing means 22 is not in sealed engagement with the housing inlet 14, thus permitting fluid to flow from the reservoir via the diptube 26 into the interior of the housing 12.
  • the fluid is retained in the interior of the housing as a valve stem inlet 28 is sealed shut against the side of the grornmet 18.
  • a tilting force being applied to the valve stem 12 Specifically, a force applied generally in the direction of arrow 30 has been applied to the part of the valve stem 12 protruding out of the housing 10. This causes the stem 12 to bear against the resilient grornmet 18 and begin to tilt.
  • the sealing means 22 are only able to move within a channel (not shown) formed from internal protrusions or the general shape of the housing 10, thus permitting the stem 12 to only be capable of movement In a single linear direction. Continued force being applied to the stem 12 causes the sealing means 22 to come into sealing engagement with the housing inlet 14 to close the fluid pathway between the reservoir and the interior of the housing 10.
  • This force also causes the stem to pivot against the grornmet to break the seal between the annular ridge 20 and the grornmet 18 to expose the stem inlet 28 and create a fluid pathway between the ulterior of the housing and the stem outlet 24 via the stem inlet 28, the newly created fluid pathway permits a dose of the fluid to be expeBed from the aerosol.

Abstract

La présente invention se rapporte à un aérosol pourvu d'une valve de dosage basculante comprenant une tige de valve (12) pourvue d'un orifice d'entrée (28) et d'un orifice de sortie (24) ; une voie pour fluide se situant entre ledit réservoir, ladite tige de valve (12) et ledit logement de valve (10) ; l'orifice de sortie (24) de la tige de valve étant sensiblement distal par rapport au réservoir et extérieur au logement de valve (10), et un moyen d'étanchéité (22) à l'autre extrémité de la tige à l'intérieur du logement, le logement de valve (10) étant pourvu d'un volume interne correspondant à la dose de fluide à pulvériser, le logement (10) étant en outre pourvu d'un moyen de guidage pour limiter le déplacement directionnel de la tige de valve (12) entre une première position lorsque le moyen d'étanchéité (22) ne ferme pas l'orifice d'entrée (14) du logement de valve et une seconde position où la tige de valve (12) a basculé et le moyen d'étanchéité (22) est positionné en prise d'étanchéité avec l'orifice d'entrée (14) du logement de valve afin de fermer la voie pour fluide entre ledit réservoir et le logement de valve (10) ; et l'orifice d'entrée (28) de la tige de valve est scellé contre une rondelle élastique (18) dans la première position et espacé de ladite rondelle (18) dans la seconde position.
