Definitions

  • the present invention relates to a fluid dispenser comprising a fluid reservoir formed with an opening, a system fluid dispenser, and a supply conduit connecting the opening from the tank to the distribution system.
  • the distribution system used comprises a perforated membrane which is subjected to a sustained vibration, for example generated by an electric piezo element. Fluid product is in contact of one side of the perforated membrane, and the vibration of the perforated membrane causes the fluid to pass through the holes in the membrane perforated so as to be dispersed in the form of fine droplets of product fluid. It is advantageous that the fluid present on the face of the membrane either at a pressure substantially equal to or slightly lower than the pressure atmospheric.
  • the present invention proposes to remedy this problem above by defining a fluid dispenser, advantageously but not exclusively with vibrating membrane, the tank of which is specially suitable for supplying the fluid product at a constant pressure substantially equal to or slightly lower than atmospheric pressure.
  • the present invention provides a product dispenser fluid comprising a fluid reservoir formed with an opening, the reservoir comprising a flexible deformable pocket in which the product fluid is stored at a pressure substantially equal to or slightly lower than the atmospheric pressure, a fluid product distribution system comprising a distribution outlet, a supply conduit connecting the opening of the tank to the distribution system, characterized in that the flexible bag contains a piece of porous material.
  • This piece of porous material serves to further improve the constant pressure inside the tank. It acts as a buffer damping during and after each distribution of fluid through the membrane.
  • the flexible pocket preferably has no shape memory or resistance sensitive to deformation, so that its capacity can be modified without appreciable variation of the pressure inside the pocket. This this is not the case with a rigid bottle with return air, since the air does not enter the tank only at the end of product distribution, where it results in the formation a depression inside the tank. This is also not the case with a follower piston system which requires a significant vacuum inside of the reservoir to raise the follower piston by suction. All these pressure variation problems inside the tank are eliminated with a freely deformable flexible pocket in which a piece of porous material.
  • the present invention can be summarized in the synergistic combination a freely deformable flexible pocket and a piece of porous material for contain the fluid to be dispensed, advantageously with a system of distribution with perforated vibrating membrane.
  • the reservoir further comprises a pocket support flexible on which the pocket is welded, the opening of the tank being formed by said pocket support, the piece of porous material being integral with said support of pocket.
  • the piece of porous material may include a connecting piece engaged in the opening of the pocket support.
  • the piece of porous material obstructs the opening. So there is no direct communication between the fluid product located in the free space at inside the flexible bag and the supply duct. On the contrary, the fluid is forced to pass through the piece of porous material to reach the supply duct.
  • the piece of porous material allows also ensure the presence of fluid at the opening of the tank.
  • the supply duct is permanently in communication with fluid.
  • the supply conduit is connected at the opening.
  • the supply duct obstructs the opening.
  • the supply duct is directly connected to the piece of material porous and the fluid soaked inside the porous material can pass directly into the supply duct.
  • the conduit feed may also contain an element of porous material to bring fluid product by capillary action from the reservoir to the distribution.
  • the distribution system and the supply ducts are mounted in a two-part shell, leaving advantageously part of the visible reservoir.
  • the distribution system includes a vibrating membrane perforated with holes through which the product fluid is distributed in the form of fine droplets.
  • the distribution can be substantially similar to those described in the documents above of the prior art.
  • the fluid dispenser of the invention comprises a system of dispensing of fluid product comprising a vibrating membrane 61 capable to be vibrated by vibration means 63, for example an element electric piezo. Electronics and power necessary for the good operation of the piezoelectric element 63 are materialized by block 8 visible in Figure 1.
  • the particular type of means used to put the membrane 6 in vibration is not a critical or essential parameter of the present invention. It is only important that the distribution system integrates a vibrating membrane in at least temporary contact with fluid. In the embodiment described, the vibrating membrane 61 is perforated with a array of holes 62.
  • the fluid dispenser of the invention comprises a tank 2 intended to contain fluid to be dispensed by the distribution described above. More specifically, the fluid product contained in the tank 2 is intended to be distributed through the holes 62 of the membrane vibrating 61 in the form of fine droplets of fluid.
  • the reservoir 2 is a flexible pocket freely deformable 2, for example made from one or two sheets of film complex welded on their periphery, except for an opening in which is engaged a pocket support 3 in a sealed manner.
  • the opening of the pocket 2 is welded to the pocket support 3.
  • the support of pocket 3 defines an opening 30 through which the fluid contained in the reservoir 2 can be extracted therefrom.
  • the walls of the flexible bag 2 can be deformed with less resistance, so that the product stored at the inside of the pocket remains at an almost constant pressure equal or slightly lower than atmospheric pressure. It is indeed easy to understand that a deformation of the flexible bag in the direction of a reduction in its capacity generates some resistance to deformation which results in the creation a slight depression inside.
  • the vibrating membrane 61 is connected to the flexible bag 2 by a conduit 5.
  • the conduit 5 is connected directly to the opening 30 of the pocket support 3.
  • the supply duct 5 extends to the inner face of the vibrating perforated membrane 61.
  • the supply duct 5 contains an element of porous material 51 which acts as a means of conveying fluid product by capillarity from the reservoir 2. This element of porous material 51 can extend as far as in tank 2 to dip directly into the fluid and thus soak.
  • the flexible pocket 2 contains a piece of porous material 4 capable of being soaked with fluid product by a capillarity phenomenon.
  • This piece of porous material 4 occupies a volume significant of the flexible bag 2 and thus allows to drain the fluid stored in the flexible pocket anywhere.
  • the piece of porous material 4 is secured to the pocket support 3, for example by engagement of a connection piece 40 formed by the piece of material porous 4 inside the opening 30 formed by the pocket support 3.
  • the piece of porous material 4 can even obstruct the opening 30, so that the fluid stored freely in the flexible bag 2 cannot directly flow through opening 30, but is instead forced to pass to through the piece of porous material 4.
  • the supply conduit 5 can be engaged in the opening 30 so as to obstruct it. So the support of pocket 3, through its opening 30, acts as a sleeve tight connection between the supply duct 5 and the piece of material porous 4.
  • the porous material element 51 contained in the supply duct 5 comes into contact with the piece of porous material 4 engaged in opening 30.
  • a continuous feeding path is created of the fluid from the flexible bag 2 to the internal face of the membrane vibrating perforated 61.
  • the piece of porous material 4 brings several advantages: firstly, it makes it possible to supply the supply conduit 55 with product fluid. Second, it acts as a depreciation buffer for pressure variations inside the flexible pouch 2. Third, it allows an almost total emptying of the flexible bag 2 because the product fluid will tend to soak the porous material rather than sit next to it the free space provided by the flexible pocket.
  • the fluid product distribution system as well as the flexible bag 2, its pocket support 3 and the supply duct 5 can be accommodated the interior of a shell 1, which can advantageously be made in two parts assembled.
  • the two parts 11 and 12 can be almost symmetrical.
  • one of the shell parts 11 must be provided with a housing for receiving the perforated membrane 61 as well as another housing for the reception of an actuation button 7.
  • the two shell parts can advantageously be provided with a window 110, 120 through which the flexible pocket 2 is visible.
  • the assembled shell 1 can be used as a housing to house the power supply and electronic unit 8 of the vibration means 63.
  • the distribution system includes a vibrating membrane.
  • the pocket flexible with its piece of porous material inside can be used with other forms of distribution systems than a vibrating membrane, such as than a pump.
