Definitions

  • the invention concerns a valve for a fluid dispensing container comprising a mounting cup to be fixed on a container, a housing to be fixed on the mounting cup and defining a channel with an inlet end and an outlet end, whereby a hollow, essentially cylindrical stem with a radial entry hole on its lower end and an axial outlet hole on its upper end is glidingly arranged in the channel, the entry hole being open to the inside of the container when the stem is in its lower position and being inside the housing when the stem is in its higher position.
  • the mounting cup has an annular wall terminating in an outer annular channel portion that is crimped in conventional way on the cylindrical wall of the container.
  • US 2015/0274404 Al concerns a valve for a container with a grommet defining a channel with an inlet and an outlet end.
  • the valve has a stem which is slideably arranged in the channel and the grommet includes a first part provided at the inlet end and a second part provided at the outlet end.
  • the stem is provided with a flange at its end.
  • US 9,387,977 Bl describes a dual function aerosol valve assembly with two stem valves.
  • 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.
  • valve stem having a valve stem, a valve stem housing, a compression spring and a hard stop formed by the interaction of the valve stem and the valve stem housing is described in WO 2014/152696 Al .
  • valve stem When the user wishes to dispense product from the container, the valve stem is vertically depressed thus having a portion of the stem base upper surface separate from sealing the bottom surface of the housing. The product is then forced by propellant pressure in the container to flow between the separated surfaces through the valve stem to exit the container to the area where the product is applied.
  • valves described above has been widely adopted, but it is not suitable for any kind of fluid.
  • Heterogeneous fluids with solid particles e.g. heterogeneous food preparations containing granular particles such as pepper sauce with grains or mustard with grains, cannot be dispensed with conventional valves of the above-mentioned type since the particles will remain blocked between the flange of the stem and the housing thereby keeping open the valve.
  • the objective of the present invention is to provide a valve which is also suitable for heterogeneous products, in particular heterogeneous products containing solid particles.
  • the stem is flange-free and in that sealing means in form of a concentric circumferential sealing protrusion on the stem are provided for the sealing between the outer surface of the stem and the housing in the upper position.
  • the invention is based on the idea that the flange of the stem which seals the lower part of the stem in the closed position against the housing will be blocked by particles contained in the heterogeneous products. As a consequence of the blocked particles, the valve will stay open.
  • a flange-free valve has been conceived, the sealing means being provided between the stem and the housing in form of a concentric circumferential conical protrusion on the stem.
  • further sealing means are at least one O-ring on the stem or in the channel of the housing.
  • the sealing protrusion is made of softer material than the housing.
  • a further alternative consists in that the sealing means are in form of a conical circumferential surface on a part of the stem.
  • This conical circumferential surface of the stem which is preferably situated at the lower end of the stem seals against the channel of the housing below the entry hole of the stem.
  • the stem is provided with two circumferential sealing protrusions of softer material than the housing, the sealing protrusions being provided below and above the entry hole.
  • the stem is provided with one conical circumferential surface and with one circumferential sealing protrusion above the entry hole.
  • a circumferential O-ring can be provided in the channel sealing against the stem below the entry hole and a concentric circumferential surface of the stem.
  • the sealing means can be freely combined in function of the requirements of the product to be dispensed.
  • spring means are provided for pushing the stem in the higher position and actuating means being provided for pushing the stem in the lower position against the action of the spring means.
  • the spring means are a helical spring arranged between the housing or the mounting cup and the upper end of the stem.
  • the spring means can be for example a metallic or a plastic helical spring.
  • the spring means can be an elastomeric body arranged between the housing or the mounting cup and the upper end of the stem. Such an elastomeric body can also be used for pushing the stem into the higher position.
  • the valve of the present invention can be used for any kind of fluid, either homogeneous fluid or heterogeneous fluid, but is particularly suitable for heterogeneous fluids, especially heterogeneous fluids containing solid particles.
  • heterogeneous fluids containing particles can be found in many fields of products, e.g. in the food sector, e.g. pepper sauce with pepper grains, mustard containing grains, etc.
  • Such heterogeneous fluids comprise a liquid phase in which solid components are dispersed.
  • the diameter of the stem has of course to be adapted to the size of the solid particles, if present in the fluid. For fluids with solid particles having a maximum diameter of 5 mm, such as pepper grains, the free diameter of the stem including its entries should e.g. be of at least 6 mm.

Abstract

L'invention concerne une vanne pour un récipient de distribution de fluide comprenant une coupelle de montage conçue pour être fixée sur un récipient, un boîtier conçu pour être fixé sur la coupelle de montage et définissant un canal à l'aide d'une extrémité d'entrée et d'une extrémité de sortie, une tige creuse étant disposée de façon coulissante dans le canal. L'invention vise à créer une vanne qui soit également appropriée pour des produits hétérogènes, en particulier des produits hétérogènes renfermant des particules solides. Par conséquent, selon la présente invention, la tige est exempte de bride et des moyens d'étanchéité sous la forme d'une saillie d'étanchéité circonférentielle concentrique sur la tige pour l'étanchéité sont ménagés entre la surface extérieure de la tige et le boîtier. Lorsque la tige passe de la position ouverte à la position fermée, elle entre au moins partiellement dans le boîtier sans que le produit soit retenu entre la bride de la tige et le boîtier.
