Definitions

  • the present invention relates to a device for dispensing a liquid containing solid particles, this device being equipped with a distribution head of the manual pump type or valve type for pressurized container.
  • Liquid distribution devices include, known manner, a container containing the liquid to be dispensed; So container is suitable for a dispensing head comprising a liquid distribution, said channel communicating with the container by a valve capable of opening and closing this communication.
  • the dispensing head can constitute a manual pump when the container is not pressurized; when the container contains a fluid under pressure, the dispensing head has a push button and a valve.
  • a hollow plunger member the most often a tube is attached to the inlet opening of the dispensing head and extends to the vicinity of the bottom of the container.
  • This plunger organ allows to draw the liquid to be distributed near the bottom of the container and use the "head up" dispensing device, i.e. without having to turn the device over so that the liquid to be dispensed either in direct contact with the inlet opening of the dispensing head.
  • distribution devices of this type have the following drawback: when the liquid to be dispensed contains solid particles in suspension, these solid particles are entrained with the liquid in the plunger and are likely to plug this plunger and the distribution channel of the head distribution and are also likely to disrupt the pump or valve operation.
  • This drawback appears, for example, when the liquid to be dispensed is a composition antiperspirant containing aluminum salts suspended in a liquid or perfume containing gold glitter of a few micrometers thick.
  • a plunger member is used in the distribution device comprising a porous element at least at the level where it gives access to the liquid to be dispensed, preferably near its free end.
  • the present invention therefore relates to a device for dispensing a liquid containing solid particles, this device comprising a container containing the liquid to be dispensed and a dispensing head carried by said container, a plunger member being fixed on the inlet opening of the dispensing head and having its free end being disposed in the vicinity of the bottom of the container, characterized in that the plunger member includes at least one porous element with open porosity through which the passage of the liquid L, the part of the plunger member not constituted by said porous element being impermeable to the liquid to be dispensed and the porous element being arranged so as to be below the level of the liquid, when the container is full and placed in its position distribution.
  • the porous element is arranged below of the liquid level when the container is full and placed in its distribution position; preferably it is arranged so as to remain fully immersed in the liquid for as long as possible dispense when the liquid is being dispensed; by therefore, the porous element is preferably arranged in the vicinity from the free end of the plunger, where it is usually found the inlet opening of the plunger member.
  • the porous element when in contact with the liquid to dispensing, is crossed by the liquid during dispensing; he therefore retains the solid particles contained in the liquid.
  • the gas passes through the element porous either under the action of pressure prevailing in a container pressurized either under the action of the vacuum generated by the pump to an unpressurized container; there is then a loss of gas at the level of the porous element.
  • the porous element is an element with open pores so to allow the liquid to pass through it.
  • the size of the pores must be suitable for retaining solid particles in the liquid to distribute.
  • the size of the pores is chosen according to the pressure difference ⁇ P under which the distribution takes place. The higher this pressure difference, the larger the pores can be small. It is within the reach of the skilled person to choose the size of the pores.
  • the porous element generally has a pore size between 7 and 250 micrometers.
  • any porous material such as than sintered glass or ceramic. It is preferable to use a material porous expanded plastic, for example expanded polypropylene.
  • porous plastic is advantageous because it allows give the porous element any desired shape and it corresponds to a low cost price.
  • the plunger member is made entirely of a porous material, which carries a sheathing over most of its surface, so as to make it waterproof, with the exception of at least one area forming the porous element.
  • Cladding can be obtained, either by placing around the plunger a plastic sheath, for example a plastic tube, either by depositing on the porous plunger a layer of substance likely to clog pores and make the plunger raincoat ; said substance may be a varnish or a paint and it can be applied using an applicator such as a brush or by spray. It is also possible to prepare the cladding during the manufacture of the porous element by molding with bi-injection of a porous plastic and a plastic impermeable to liquid to be dispensed.
  • the plunger member is a member impermeable to the liquid distribute, for example a plastic tube, and the opening located at its free end is closed by the porous element.
  • the element porous has, preferably, the shape of a bowl, which is fitted by its edge on the free end of the plunger member.
  • the plunger member advantageously has the shape of a cylinder having, in particular, a circular section. But, when it is made entirely of porous material, it can be molded according to any shape: sinusoidal, zig-zag or a shape aesthetic, for example, a silhouette; indeed, the plunger porous can easily be deformed for its introduction into the container and can then return to its original shape in the container.
  • the plunger is made of porous plastic, the porous plastic is flexible; by cladding with a substance impermeable to the liquid to be dispensed, it is then possible more or less rigidify the plunger member in any form.
  • FIG. 1 represents a distribution device of the type "aerosol can", generally designated by the reference 1.
  • This dispensing device comprises a container 2 provided with a bottom 3 and a neck 4.
  • the container 2 contains a liquid L to be dispensed containing solid particles and a liquefied propellant; above of the liquid phase the propellant is in the gas phase, which pressurizes the container to a pressure equal to the vapor pressure of the propellant at liquid phase temperature.
  • neck 4 of container 2 is fixed by screwing or crimping a dispensing head 5.
  • This distribution head is provided with a distribution channel opening at 6 and a valve (not shown) capable of in communication the container 2 and the distribution channel.
  • a plunger member designated by 7 On the hole valve inlet is fixed a plunger member designated by 7 in its together.
  • This plunger member is constituted by a cylinder 8 in expanded polypropylene onto which a spray has been deposited varnished to form a sheath 9 over most of its length, except in the vicinity of the free end of the cylinder 8; we thus forms at the end of the plunger a porous element 10 whose free end 11 is located near the bottom 3 of the container 2.
  • the liquid L containing solid particles, which is contained in container 2 enters under the action of gas pressure in the plunger member by the porous element 10.
  • the liquid L is therefore filtered through the element porous 10 of the plunger member; pore size of the organ plunger is chosen to avoid clogging of the porous element 10 by the solid particles of liquid L.
  • Figures 2 and 3 show a second mode of realization of a distribution device according to the invention.
  • the device 101 comprises a container not pressurized, the outlet of the liquid L to be dispensed being provided by a head 105 with a manual pump.
  • the elements of this embodiment similar to those shown in Figure 1 bear the same reference to which 100 has been added.
  • the organ plunger 107 is constituted by a hollow cylindrical tube 108 in polyethylene, impermeable to liquid L.
  • this element 110 has the shape of a bowl and has a flat wall 113, which closes the opening 114 of the tube 108 and a cylindrical side wall 112 which constitutes the edge of the bowl and surrounds the wall of the tube 108 at its free end.
  • the tube 108 can have an external diameter of 1.6 mm and a wall thickness 0.35 mm.
  • the flat wall 113 of the porous element 110 has a thickness of 1 mm and the distance between the bottom 103 of the container and the flat wall 113 is 0.5 mm.
  • the filtering function is performed in the same way as for the device in FIG. 1.
