Definitions

  • the present invention relates to a device for spraying a liquid, comprising a pressurized container provided with an additional gas intake valve.
  • Aerosol type spraying devices consist of a container containing a product in liquid form to be sprayed and a propellant.
  • the propellant is, in known manner, a liquefied gas such as chlorofluorinated hydrocarbons, propane or butane, or a compressed gas, for example compressed air.
  • the container is fitted with a valve for the outlet of the pressurized liquid. This valve is fixed to a valve cup, so that the fixed valve body opens in the container and the movable element opens outside the container, the valve being opened by translation or depression of the movable element in the valve body.
  • the insertion of the movable element of the valve is generally obtained using a push button, capable of pressing on the movable element of the valve, push button that the user can move in translation manually to activate the valve.
  • the push button generally comprises an ejection channel for the product to be dispensed and a spray orifice.
  • a dip tube is generally fixed to the valve body, this tube plunger to supply the valve body with liquid to be sprayed, even when the liquid level is low.
  • the pressure in the container is generally limited to about 12 x 10 5 pascals.
  • the pressure in the container decreases as it is dispensed; it follows that at the end of dispensing and in the absence of additional gas intake, the spraying is generally not satisfactory because the pressure is insufficient to spray adequately by mechanical effect at the dispensing orifice. since the initial pressure is capped.
  • the present invention therefore relates to a spraying device comprising a container pressurized by means of a non-liquefied compressed gas, said container being provided with a distribution valve with additional gas intake and with a dip tube fixed to the body of valve, characterized in that the additional gas intake is made through a sintered element having dimensions and a porosity such that, under a pressure difference of 10 ⁇ 10 5 pascals, the flow of gas passing through the sintered element is between 10 and 50 cm 3 / sec.
  • the sintered element used has, in general, pores with an average diameter of between 0.1 and 5 micrometers.
  • the sintered elements are, in known manner, obtained by agglomeration, by heating and / or by compression of a pulverulent material such as glass, ceramic, metal or plastic, for example polyethylene. According to the present invention, it is preferable to use the sintered elements sold by the company "POREX” under the trade name "POROUS PLASTICS".
  • the additional gas flow depends on the dimensions and the nature of the sintered element, that is to say the average path traveled by the gas in the sintered element and the contact surface between the gas and the sintered element.
  • the sintered element is a cylinder, it depends on the section and the length of this element.
  • the dip tube is located in the axis of the supply duct of the valve body and the additional gas intake is perpendicular to said supply duct;
  • the sintered element may have the shape of a cylinder.
  • the additional gas intake is located in the axis of the supply duct of the valve body and the dip tube opens perpendicular to this axis;
  • the sintered element may have the shape of a cylinder.
  • the sintered element has the shape of a ring arranged in the valve body, so as to surround the opening of the supply duct of the valve body, the gas intake additional being made entirely through said ring by means of openings made in the wall of the valve body opposite said ring.
  • the device represented in FIG. 1 is generally designated by the reference 1. It consists of a container 2, comprising a valve 3 actuated by a push button 5.
  • the container 2 consists of side walls of generally cylindrical shape closed at one end by a bottom (not shown). At the end opposite the bottom, the walls form a dome and the container is closed by a cup 4 of valve 3.
  • the valve 3 is fixed to the center of the valve cup 4 which is fixed to the container 2 by a crimping bead.
  • Said valve 3 comprises an emerging rod 6, which is movable in translation and emerges outside the container 2, and a valve body 7 which is fixed and which opens in the container 2; the valve stem 6 slides in the valve body 7 to cause the valve 3 to open.
  • a push button 5 is fixed by interlocking on the emerging stem 6; it includes a cylindrical side skirt 5 a , the lower edge of which stops at a distance from the cup 4 and the upper edge of which is connected to a flat upper part 5 b , on which the user presses to actuate the valve 3.
  • an ejection channel 8 In the push button 5 is formed an ejection channel 8, this channel comprising two sections arranged at right angles; a first section 8 a is arranged coaxially with respect to the emerging rod 6 and a second section 8 b arranged at right angles opens in the side skirt by a recess where a spray nozzle is forced into, the orifice 9 has a diameter much smaller than that of section 8 b .
  • the valve body 7 is provided with a tube 10 of smaller diameter forming a supply conduit for the valve body. On this tube 10 is force-fitted a dip tube 11.
  • the additional gas outlet 12 opens in the valve body 7; it consists of two right-angled sections 12 a and 12 b .
  • the section 12 a is perpendicular to the longitudinal axis of the container 2 and opens in the valve body 7.
  • the section 12 b opens above the level of the liquid L to be sprayed.
  • the section 12b contains a sintered element 13 which has the shape of a cylinder and which has been introduced by force.
  • FIG 2 is shown schematically another embodiment of the invention.
  • the push button and the container as well as the valve are identical to those shown in Figure 1.
  • the cup designated by the reference 104 and the valve body 107 have been shown.
  • an additional gas intake constituted by a pipe 112 provided with a lateral tube 112 a .
  • a dip tube 111 bent at a right angle On this lateral tube 112 a is fixed a dip tube 111 bent at a right angle; the tube 111 is fixed to the lateral tubing 112 a , perpendicular to the longitudinal axis of the container; it extends, for the rest of its length parallel to the longitudinal axis of the container.
  • the sintered element 113 is cylindrical and it is forced into the conduit 112 below the lateral tube 112 a . A result similar to that indicated for the first embodiment is obtained.
  • FIG. 3 is shown schematically another embodiment of the spraying device according to the invention.
  • the push button and the container are identical to those illustrated in FIG. 1.
  • the valve body 207 is delimited by a cylindrical side wall 214 closed at its base by a partition 215 perpendicular to the longitudinal axis of the container.
  • the partition 215 is connected in its central zone to a cylindrical end piece 210 turned towards the inside of the container forming the supply conduit of the valve body. On this endpiece is fixed the dip tube 211.
  • At the lower part of the side wall 214 and at the periphery of the partition 215 are formed lights 216.
  • the sintered element 213 rests on the partition 215; it has an annular shape and its outside diameter is equal, except for the necessary clearance, to the internal diameter of the side wall 214 and its internal diameter equal to the internal diameter of the end piece 210.
  • the sintered element 213 has a thickness such that the openings 216 are entirely opposite the sintered element 213.
  • the compressed gas enters through the ports 216 in the element 213 and passes through it. Results similar to those described for the first embodiment are obtained.
  • a spraying device was used as illustrated in FIG. 1; the container of this device has an internal volume of 270 cm 3 ; contains 150 cm 3 of spray liquid with a viscosity of 15 cps; the propellant is compressed air, initially under 10x10 5 pascals; the orifice of the spray nozzle has a diameter of 0.20 mm.
  • the results were compared without additional gas intake and with an additional gas intake containing a cylindrical sintered polyethylene element 2.4 mm in diameter and 1.75 mm in length having a pore diameter of 2 micrometers; the flow rate of the frit is 50 cm 3 / sec. under a pressure difference of 5 x 10 5 pascals.
