Definitions

  • the invention relates to a liquid product suction device in a dispenser comprising a reservoir equipped with means for sampling the product.
  • the invention also relates to a liquid product dispenser comprising such a suction device.
  • the invention finally relates to a method of manufacturing such a suction device.
  • the invention applies more particularly to the distribution of cosmetic or pharmaceutical products from a reservoir equipped in particular with means for sampling the product.
  • It can be a rigid or flexible tank. It can also be a tank without air intake, or with air intake.
  • a depression is installed in the tank and the sampling system must overcome this depression to continue to work properly, or the internal volume of the tank is reduced either by deforming if the tank is flexible, or by a movable bottom provided with sealing means, via a piston for example, if the tank is rigid, to compensate for the vacuum as well created.
  • the means for sampling the product generally consist of a pump associated with a push button.
  • the pump has a central hole.
  • the product enters the orifice of the pump, either directly if the tank is without air intake, or via a plunger tube extending the pump if the tank has a return air. In both cases, the product enters centrally into the pump. It is a so-called centralized aspiration.
  • This type of central aspiration has a high suction speed because the product enters the pump directly without loss of load.
  • the present invention aims to overcome the various disadvantages mentioned above, by means of a suction device whose suction speed is lower, and which adapts to any type of tank.
  • the main idea of this invention is to first suck the product annularly and then centrally.
  • the product therefore follows a course different from that of the prior art. It is no longer directly drawn into the pump or into the tube connected to the pump centrally, but it is deflected in annular suction means which create a pressure drop before being sucked into the pump. This pressure drop makes it possible to significantly reduce the speed of suction of the product within the dispenser, and thus to avoid the phenomenon of phase shift of the product which alters its chemical properties, and / or the phenomenon of unsightly suction flow. .
  • said annular suction means comprise an annular suction inlet having a section greater than the inlet section of the central suction channel.
  • the product will first pass through a relatively large first inlet section and annularly localized, which forces it to take a turn in its path and thus to slow it down, and while decreasing the pressure of the product. thanks to the large section, then through a second smaller and centrally located entrance section, which forces him to take an extra turn in his course with a decrease in surplus section, which slows down his suction speed, and this gradually.
  • the suction is thus carried out in a clean way inside the tank, and with a speed calibrated so that the output of the product outlet of the dispenser is sufficient to satisfy the consumer, while avoiding overspeed so that the product remains stable within the tank.
  • the invention also relates to a liquid product dispenser comprising a reservoir equipped with a suction device for the product as described above.
  • This method is very advantageous since it allows to mold the entire suction device at once, and thus to obtain a single piece, which allows a considerable time saving in the manufacture of the device. It also simplifies the manufacture of the device, compared to an assembly of two parts (lower part and upper part) which must then be provided with expensive and complex fixing means of implementation.
  • the upper part consists of a purge ring
  • the latter generally equips a liquid product dispenser without air intake.
  • This purge ring comprises a deformable sealing lip housed inside a protective part provided to fit inside the reservoir, the deformation of the lip during assembly of the ring in the provoking tank the air purge tank.
  • the idea is to systematically associate a protective piece intended to protect the fragile lip of the purge ring, from its manufacture and until it is mounted in the dispenser.
  • the function of the purge ring is to purge the residual air present in the tank at the time of assembly of the dispenser.
  • the purge ring is activated only during the assembly of the dispenser, so that it can be put into service without air intake.
  • the purge ring does not intervene once the dispenser is put into service and delivers doses of product.
  • the absence of air in the tank is then ensured either by deformation of the tank or by a movable piston.
  • the suction device shown in the various figures is intended to be mounted on distributors of liquid or semi-liquid products.
  • the suction device according to the invention could very well be mounted in a distributor operating with air intake.
  • the reservoir may consist of a flexible pocket-type reservoir, or a rigid reservoir of the vial type.
  • This tank may or may not contain a piston, or any other system allowing the distributor to operate without air intake.
  • Such a distributor head may include a residual air during its assembly on the tank during the conditioning operation. This residual air can cause disruption in the use of the product to be dispensed.
  • a flexible purge ring 1 is added to the dispensing head, and ensures the air purge function, before the normal use of the dispenser.
  • This purge ring 1 is attached to the neck 2 of the dispensing head.
  • This lip 12 is generally made of a flexible material, for example a low density polyethylene, or else based on elastomer, and is fragile, in particular at its thinned end which is intended to come into bearing contact, under slight stress against the inner wall of the tank.
  • the purge ring 1 also comprises an axial sleeve 13 centered on the cap 11 and defining a centralized suction channel 8, opening on an orifice 14 formed in the cap 11.
  • This orifice 14 consists of the inlet of the suction channel centralized 8.
  • This socket 13 is provided with clipping means for attaching to the pump 5.
  • the ring 1 is thus fixed to the pump 5 and protrudes in the lower part of the dispensing head.
  • the lip 12 is separated from the neck 2 by an interstice e. The lip 12 is thus exposed, without any protection around it, and can be damaged during the bulk storage of the dispensing heads thus equipped with rings 1.
  • the ring When mounting this dispensing head to a tank, the ring performs the purge of the tank by overpressure. This will be described in more detail in the following figures.
  • the dispenser When the purge is done, the dispenser is ready for use. The user can then take a dose of the product contained in the tank by pressing the push button 4 of the dispensing head.
  • the product contained in the reservoir is then sucked and passes through the inlet 14 of the centralized suction channel 8, then through the centralized suction channel 8 of the bushing 13, and then into the pump 5 to be conveyed to the push button 4 and escape from the dispenser.
  • the product present in the tank thus enters directly into the centralized aspiration channel 8, along the X axis.
  • the suction speed is relatively high since there is no obstacle on the path of the product, except for the input of the centralized distribution channel which limits the amount of product taken during a press on the push button 4.
  • this suction which makes abruptly pass the product 7 of the static state in a mobile state at high speed can cause a phase shift of the product and / or the appearance of a relatively unsightly suction flow especially when the tank is transparent.
  • the figure 2 shows a dispensing head according to the invention. It is analogous to that of the figure 1 for elements with the same reference, except collar 2 and purge ring 1.
  • the neck 2 is now provided with a peripheral skirt 24 extending towards the ring 1 so as to protect its lip 12.
  • the collar 2 conventionally comprises a disk 21, of circular or oval section for example, provided with a central orifice from which extends a central sleeve 23 in which is inserted the lower part of the pump 5.
  • This neck 2 also conventionally comprises an annular return 22 directed towards the push button 4 and allowing the centering and wedging of the trim band 3.
  • the neck 2 comprises according to the invention a peripheral skirt 24 connected to the periphery of the disk 21 and extending in a direction opposite to the annular return 22.
  • the lip 12 of the ring 1 comes bearing against the inner wall of this peripheral skirt 24, as the embodiment described in the figure 1 .
  • the airtightness between the dispensing head and the reservoir is not provided by the ring 1 but by the peripheral skirt 24 of the neck 2. This skirt 24 thus bears tightly against the inner wall of the reservoir.
  • the ring 1 as for it always comprises a cap 11 of frustoconical shape, but with a much more obtuse angle, allowing a consequent reduction of the height of the ring 1.
  • the cap could also be hemispherical.
  • the sealing lip 12 is directed parallel to the central axis X of the ring 1.
  • This lip 12 is connected to the periphery of the cap 11 by a concave portion 15.
  • the lip 12 comes into contact, by arcboutement, with the wall internal of the peripheral skirt 24 of the collar 2.
  • the lip 12 of the purge ring 1 is thus housed in the skirt 24 of the neck 2.
  • This lip 12 is thus protected in case of bulk packaging of the dispensing heads and their sealing can be checked before assembly on the tank 6.
  • the neck 2 therefore acts as a protective piece for the ring 1.
  • this ring is illustrated in figure 3 .
  • the skirt 24 sealing collar 2 is housed in the reservoir 6.
  • the descent of this head in the product 7 causes a slight overpressure in the reservoir 6 which deforms elastically the lip 12 of the purge ring 1 so that the residual air present in the reservoir 6 can pass between the skirt 24 of the neck 2 and the lip 12 of the ring 1 to escape from the reservoir 6.
  • This air is then contained in a space provided for this purpose between the ring 1 and the neck 2.
  • a slight overflow of the liquid product 7 in the same space, after having driven air over the flexible lip 12, ensures the complete purge of the assembly, as illustrated by the two lateral arrows.
  • This reservoir 6 can be flexible or rigid, contain a piston (or another system) or not to monitor the variability of the volume of product 7.
  • This piece 9 is a piece of revolution centered on the X axis and extending orthogonally to the X axis. It preferably follows the profile of the cap 11 located just above.
  • the cap 11 has a generally flat shape, with a slight bulge at its central area from which the sleeve 13 protrudes. This bulge gives a slightly rounded shape to the cap 11 in this central portion.
  • the piece 9 follows this rounded profile, and more precisely consists of a bowl.
  • the piece 9 has no orifice.
  • the product must thus bypass the part 9, take a first sharp turn to enter the annular passage 16, then take a second sharp turn to enter the central aspiration channel 8. This course greatly reduces the suction speed of the product. It is no longer a central aspiration, but an annular suction.
  • the inlet section of the annular passage 16 is greater than the inlet section 14 of the central aspiration channel 8. This gradual decrease of the suction section, as the product travels, provides a suction less violent, more fluid, so as not to rush the product and it maintains its stability.
  • the suction device according to the invention finally consists of a body consisting of an upper part consisting of the ring 1, and a lower part consisting of the part 9.
  • the inlet of the annular passage 16 is at the level of perimeter 93 of part 9.
  • the ring 1 and the part 9 may consist of two separate parts, connected via conventional assembly means.
  • They may advantageously consist of a single piece obtained by molding, as presented on the Figures 4 and 5 .
  • the ring 1 and the part 9 are molded in a single mold.
  • such a molding poses a difficulty of demolding at the annular passage 16, because the cup-shaped part 9 prevents access to the inside of the annular passage 16 to be able to demold this area correctly.
  • the cup-shaped part 9 is molded with a concave curvature, in order to completely clear the area of the annular passage, as shown in FIG. figure 4 .
  • This concave curvature consists of a curvature opposite to that of the central part of the cap 11 of the ring 1.
  • the part 9 and the central part of the cap 11 of the ring 1 are connected via connecting tabs 91 leaving between them zones of openings 92 for the passage of the product to the centralized suction channel 8.
  • the material used for the ring 1 and the part 9 consists of a flexible material having elastic properties, of the elastomer type, in order to allow such a roll-up of the part 9.
  • the body constituting the suction device is thus manufactured in only two steps, that is to say a molding step of its upper 1 and lower 9 parts, and a step of reversal of its lower part 9.
  • ribs 17 are provided on the lower surface of the cap 11 of the ring 1, and are distributed evenly. These ribs 17 are molded with the ring 1. The upper surface of the part 9 can thus come into contact with these ribs 17, which allows to leave a constant space between the upper surface of the part 9 and the lower surface of the cap 11 of the ring 1.
