Definitions

  • the present invention concerns pressurised receptacles able to contain a fluid, and more particularly the means of closing such pressurised receptacles.
  • Known pressurised receptacles are of the aerosol type.
  • An aerosol is a set of solid or liquid particles of a chemical substance given in suspension in a gaseous medium.
  • the term “aerosol” also designates the receptacle containing a mixture of a product and a propellant gas.
  • the propellant gas creates a pressure inside the receptacle.
  • By opening an outlet valve the mixture is expelled outside the pressurised receptacle.
  • the product is atomised in the form of an aerosol, that is to say in fine particles in suspension in air.
  • the propellant gas is normally nitrogen since it is an inert gas and therefore less dangerous than propane, butane and other flammable hydrocarbons, which do not however have an effect on the ozone layer.
  • a known aerosol receptacle comprises a bottom, a lateral wall and a neck, and is usually produced from aluminium.
  • the thickness of the receptacle is designed to withstand up to 18 bar pressure inside.
  • aerosol receptacles having various capacities.
  • Aerosols that is to say the pressurised receptacles provided with a non-removable dispensing valve, are governed by very strict and draconian safety standards.
  • the dispensing valves are not removable and they do not make it possible to effectively measure out the flow of product emerging from the pressurised receptacle.
  • the internal pressure allowed by the standards is limited to 12 bar at 50° C.
  • the filling of known aerosols is limited by strict standards to 66% of the volume, which is itself a maximum of one litre.
  • a first problem proposed by the present invention is to design a closure means for a pressurised receptacle able to contain a fluid that is removable and makes it possible to measure out the emerging product, and the safety in use of which is ensured up to pressures of more than 20 bar.
  • a second problem that is at the basis of the present invention is to design a pressurised receptacle that allows an intermittent thrust and can contain and dispense even a granular fluid.
  • the idea that is at the basis of the invention is to design a reliable removable measuring cap and to use it in association with a receptacle containing a fluid at a pressure appreciably greater than the pressures normally allowed for aerosols, for example around 30 bar.
  • a measuring cap for a pressurised receptacle able to contain a fluid comprising a bottom and a substantially cylindrical lateral wall that narrows towards a neck having a front neck face and an internal neck edge, comprising:
  • Such a measuring cap is removable.
  • the receptacle that it closes can easily be reused, which reduces the quantity of waste produced.
  • Such a measuring cap is therefore ecological.
  • Such a measuring cap does not comprise a valve.
  • the pressurised receptacle provided with such a removable measuring cap is not constrained by the strict aerosol standards, nor by other rules if the volume of the receptacle is less than one litre and the pressure produced per volume is less than 50 bar/litre.
  • This measuring cap is simple in design; it comprises only three main elements that can be preassembled, and a fourth element to be assembled in order to connect the measuring cap to the pressurised receptacle. It is therefore also simple to use.
  • Such a measuring cap is compatible with conventional receptacle bodies for aerosols so that it is possible to profit from the low cost of these mass-produced receptacles.
  • the cap according to the invention is a measuring cap and the user can therefore choose the rate of flow of product out of the pressurised receptacle.
  • the radial peripheral protrusion comprises a frustoconical portion, the cone angle of which corresponds substantially to the inclination of the internal neck edge of the receptacle.
  • the penetrating part can comprise at least one recessed lateral face defining a width less than the diameter of the neck of the receptacle.
  • the measuring cap can advantageously be made for the measuring cap to be produced from metal or plastics material.
  • plastics material reduces the manufacturing costs of the measuring cap since plastics material is less expensive than metal. However, metal will have better mechanical strength.
  • the metal in the case of a metal measuring cap, provision can advantageously be made for the metal to be stainless steel or an aluminium alloy.
  • the assembly ring can be fixed to the body by screwing, pressing or cottering.
  • the penetrating part of the body can comprise two lateral flats on either side of the longitudinal axis of the body. One of these two flats producing the lateral face.
  • the assembly ring can advantageously be made for the assembly ring to comprise a peripheral skirt surrounding the neck of the receptacle, leaving a leakage space between its end edge and the peripheral wall of the receptacle.
  • the assembly ring By surrounding the neck of the receptacle, the assembly ring also fulfils the function of reinforcement of the neck, opposing the action of the internal pressure of the receptacle, which tends to enlarge the neck.
  • the closure member prefferably be a rod slidably mounted in the axial fluid passage between a closure position and an open position, and comprises two annular grooves able to receive annular closure joints.
  • the travel of the closure element is limited between two predefined positions. This prevents any risk of the closure element leaving the axial fluid passage unexpectedly.
  • the closure member can advantageously be made for the closure member to be a locking screw that is actuated by screwing or unscrewing in the body.
  • the penetration of the locking screw in the body is chosen precisely by a user by screwing this locking screw to a greater or lesser extent. And the structure is well suited to applications in which the fluid contains powders or solid suspensions.
  • closure member also to comprise a closure element positioned in the axial fluid passage close to the neck of the receptacle and held distant from the latter by a spring or by the internal pressure of the receptacle.
  • the closure element fulfils a dual function, namely the valve function during filling and the safety element function.
  • the invention provides a receptacle able to contain a pressurised fluid, closed by a measuring cap according to first aspect of the invention, and having an initial internal pressure greater than 20 bar.
  • Such a receptacle does not need to comply with aerosol standards since it does not comprise a fixed valve and the cap is removable.
