Definitions

  • a system for dispensing a liquid such as perfume includes a liquid dispensing apparatus and a liquid reservoir.
  • Such systems are known for dispensing a liquid such as perfume and which each comprise a device for pumping liquid and dispensing the pumped liquid as well as a liquid reservoir on which the device is permanently mounted.
  • a device for pumping liquid and dispensing the pumped liquid as well as a liquid reservoir on which the device is permanently mounted.
  • the second end of the dip tube forms a perforation member which extends to the bottom of the reservoir in order to pump the liquid there under the action of the pump.
  • the dimensioning of the rigid tube must be very precise so that the tube is able to reach the bottom of the tank without however touching it so as not to damage it.
  • the tube must therefore be of a length less than the inner length of the tank, which will therefore not guarantee its complete emptying.
  • the invention provides for remedying at least one of the aforementioned drawbacks by proposing a new liquid distribution system that is more reliable than those of the prior art.
  • the subject of the invention is thus a system for distributing a liquid in accordance with claim 1.
  • the liquid reservoir is not an integral part of the device but is installed in it removably.
  • the tank has its own liquid return (or rise) system (internal suction tube or dip tube) which reacts under the action of a vacuum caused by the pumping and distribution device in order to bring the liquid back up. from the bottom of the tank to the top of it.
  • the main hollow needle only serves as a first interface to, on the one hand, perforate the reservoir and, on the other hand, allow the liquid brought from the bottom of the reservoir to exit from the latter and be conveyed to the device. pumping and distribution.
  • the main hollow needle does not have the function of fetching the liquid from the bottom of the reservoir as in the prior art and is therefore not part of the liquid return system. Thus, there is no need to size a hollow needle very precisely so that it can pick up the liquid at the bottom of the tank without damaging it, the tank being in fact already equipped with its own liquid return system. .
  • the secondary hollow needle serves, for its part, as a second interface for, on the one hand, perforating the reservoir and, on the other hand, bringing the external air of compensation inside the reservoir (return means d 'air).
  • the apparatus according to the invention is judiciously designed so that the said at least two main and secondary needles serving as fluidic interfaces (as explained above) between the pumping and distribution device and the reservoir are integral with one part. intermediary of the apparatus which is distinct from said device.
  • the device can be a device conventional as found in the trade and only the part of the device comprising the part with the needles is specific.
  • the device for pumping and dispensing liquid can therefore be replaced without having to touch the part to which said at least two needles are subject.
  • the device is therefore particularly simple to design and manufacture since it does not require the design of a specific pump.
  • the pumping and liquid distribution device used in the device incorporates in itself its own ventilation system.
  • the configuration of the device is therefore simple since it uses the sealing capacity of the venting system of the pumping device and therefore does not require a separate and independent venting system: when the pumping device is not activated, the venting system is not activated and outside air cannot enter the device and the secondary needle. On the contrary, when the device is actuated, the outside air enters the device via the venting system which is open and reaches the secondary needle and therefore the reservoir with which the needle. makes the connection.
  • the activation of the venting system therefore does not require a separate action on the part of the user since it systematically intervenes as soon as the pumping action is exerted by the user.
  • the liquid is pumped from the bottom of the tank through the free end of the dip tube, rises in the main needle which is connected to the tube and passes through the pumping and dispensing device to be distributed outside.
  • the fluid circuits or paths for air and liquid are sealed with respect to each other so as not to disturb or even hinder the operation of the system (the two circuits or paths are physically separated in order to avoid preferentially sucking in air when pumping liquid).
  • the secondary needle is not in contact with the main needle in the reservoir insofar as said main needle is tightly connected to the dip tube.
  • the liquid reservoir When the liquid reservoir is empty, it is removed from the device and another full reservoir is put in its place.
  • the device can therefore be reused a many times without having to throw away the entire distribution and pumping system (device and tank).
  • the mounting of the needles on an intermediate part of the device (forming a needle support), independent of the pumping and dispensing device, makes it possible to fix the needles more reliably (for example by overmolding) than on said device.
  • the risks of the needles detaching from the part forming the support over time are reduced compared with the apparatus of the the aforementioned prior art.
  • hollow needles for example of the hypodermic needle type, makes it possible to have a liquid reservoir which is permanently closed (during transport and use) and which does not need to be opened in order to be used. In fact, it suffices to introduce the reservoir into the device and to put it in place in the position of use by pushing it towards the needles so that they perforate the reservoir (more particularly the means of plugging or closing the tank) and that, by actuating the distribution device, liquid can be distributed (eg sprayed) and air introduced into the tank.
  • the simple gesture of removing the empty tank from the device allows you to disengage the needles from the tank and replace the empty tank with a full tank.
  • the main needle is not intended to go to the bottom of the reservoir insofar as the latter already incorporates its own liquid return system (dip tube). Therefore, the length of the needle must be sufficient to be able to perforate the reservoir and penetrate inside without having to extend to the bottom as in the prior art.
  • the length of the main needle (like that of the secondary needle) is thus considered to be small in relation to a main dimension of the reservoir, for example in relation to the length or height of the reservoir if the latter has a general shape. elongated, for example substantially cylindrical.
  • the needles can be much shorter than the piercing tube of the above apparatus. It follows that the race to be carried out by the needles to exit the reservoir is much smaller than in the prior art, which can make the withdrawal movement easier. Moreover, as these needles are short, the risk of breaking them is lower than in the prior art. In addition, the part of the main needle capable of plunging into the liquid is small (or zero depending on the arrangement) so that the reservoir change can be carried out cleanly, without the liquid dripping. Finally, as the needles are short, it is possible to provide a covering to hide them and prevent the user from injuring himself, whereas in the state of the art, it is impossible to produce a covering completely masking the needle. at the risk of not being able to access the tank.
  • the needles can be arranged in different configurations: side by side in a contiguous manner or well apart from one another, centered or not with respect to the tank, concentric with respect to one another, etc. .
  • the needles can also adopt different lengths with respect to each other, or even different internal diameters.
  • the needles usually have a bevel-cut perforator end like the hypodermic type needles.
  • the dip tube can be flexible (plastic), which facilitates its installation inside the reservoir to the bottom thereof.
  • the flexible dip tube can be longer than the interior height of the reservoir and, because of its flexibility, it therefore curves in contact with the bottom of the reservoir, thus making it possible to guarantee the full return of the liquid. This configuration allows it to absorb the variations in height that may exist from one tank to another.
  • the invention further relates to a method of installing a liquid reservoir in a liquid distribution apparatus of a liquid distribution system as briefly described above, the method comprising the introduction of the reservoir in the apparatus and its placement in said apparatus in a position of use in which said at least two hollow needles perforate the liquid reservoir with a view to sucking the liquid therefrom as a result of a pumping action on the device for pumping liquid and distributing the pumped liquid.
  • the figure 6 shows tank R without the device.
  • the device A has a generally elongated shape along a Z axis (this axis corresponds to the vertical axis when the device is in the vertical position of use as on the figure 1a ).
  • Apparatus A more particularly comprises an outer casing 12 having a generally hollow cylindrical shape.
  • the casing 12 has two opposite open ends 12a, 12b which are arranged along the longitudinal axis Z.
  • the cylindrical shape of the outer casing 12 extends from its so-called lower end 12b over almost its entire height. Near the upper end 12a the casing takes the shape of a truncated cone towards the end 12a to form a reduced opening relative to the opening of the opposite lower end 12b.
  • the apparatus A comprises a device 14 for pumping liquid and distributing the pumped liquid which is mounted at the upper end 12a of the casing as shown generally in FIG. 1a.

  • a second elongated tab 94 extends, from the flange 71, inside the window 90 (over part of its height), immediately adjacent to the first tab 92.
  • the second tab 94 is provided at its free end with a return or lug 94a directed outwards.
  • the second tab is not disposed parallel to the cylindrical wall of the sheath but is inclined relative to the latter.
  • the free end of the second tab 94 projects out of the window 90 in the rest position ( figures 4 and 5 ).
  • the second tab 94 thus shaped has radial and also lateral elasticity.
  • the lug 94a comprises a part which is inclined laterally in the direction of the lug 92a adjacent.
  • the lug 92a comprises, for its part, a recessed or recessed part on the side adjacent to the lug 94a in order to cooperate with the inclined part of the latter when the second lug 94 is deformed laterally in the direction of the first lug 92 as c 'is the case during the movement of insertion of the reservoir into the sheath ( figures 8a-e ).
  • the inclined part of the lug 94a has for example a cutaway 94a1 and the hollowed out or erased part of the lug 92a has a complementary cutaway 92a1, thus promoting support of the two sides against one another.
  • a spring 93 is mounted coaxially around the body 32 and is held in compression between an upper stop formed by the lower face of the collar 60 and a lower stop formed by the upper face of the end flanges 78a, 80a, 82a.
  • the R tank shown on figure 6 has a generally cylindrical shape and is hermetically closed by a stopper means. As shown in more detail and on a larger scale on the figure 7a , the reservoir has an open upper end configured in the form of a neck 100 which defines a passage 101 for placing the interior of the reservoir in communication with the exterior.
  • the reservoir comprises a part forming an insert 102 engaged inside the passage delimited by the neck and which is held there in position.
  • the plugging means 104 (sealing part) of the reservoir covers the insert 102 in order to ensure the tightness of the reservoir.
  • the closure means is configured to be capable of being perforated by the needles 50 and 52 of the apparatus.
  • the stopper means is for example made of a material which can be punctured by needles 50 and 52. This material may or may not be able to close again after removal of the needles.
  • the plugging means is, for example, a membrane which has sufficient thickness so that, when the needles are withdrawn, the plugging means closes and thus ensures tightness. However, the thickness should not be too great so that it can be easily punctured by the needles.
  • the thickness varies in particular depending on the nature of the material and the diameters of the needles. For example, the thickness can vary from 1 to 5mm.
  • the material constituting the closure means is for example made of elastomer (eg rubber).
  • the material could be thermoplastic, silicone, foam ...
  • the two cavities or chambers 106 and 110 are isolated from one another.
  • the main hollow needle 50 is intended to penetrate into the central cavity 106, while the secondary needle 52 is intended to enter the peripheral cavity 110 so as to allow the entry of air into the reservoir ( air intake) through orifice 110a when pumping liquid (the venting system of device 14 is automatically opened under the action of pumping as explained in relation to the figures 1b and 1c ).

  • the central cavity 106 of the insert 102 is delimited by a central cylindrical portion 102b which is higher than the rest of the body and in particular than the shoulder 102a. This difference in height makes it possible to produce a tubular seal between the two cavities 106 and 110. The insulation reliable between the two cavities is thus easier to obtain than by trying to achieve a flat seal.
  • the elastomeric plugging or sealing part 104 is shaped on its lower face so as to fit into the upper part of the insert 102 and, in particular, on the free end of the central cylindrical portion 102b as well as in an annular groove 102c of the shoulder 102a.

  • the lower part 114b of the part 114 is brought, by crimping, to bear under an external shoulder of the neck 100.
  • the part 114 forms in the upper part an internal return 114c directed towards the central part 104a and which extends above the shoulder 102a and the collar 104b.
  • Part 114 forms a crimping cap
  • the internal return 114c is inclined downwards in the direction of the collar 104b so as to firmly press said collar.
