Definitions

  • the invention relates to a device for suctioning liquid product into a dispenser comprising a reservoir equipped with means for withdrawing the product.
  • the invention also relates to a liquid product dispenser comprising such a suction device.
  • the invention relates to a method for 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 collecting the product.
  • It can be a rigid or flexible tank. It can also be a tank without air intake, or with air intake.
  • the means of sampling the product generally consist of a pump associated with a push button.
  • the pump has a central orifice.
  • the product enters the orifice of the pump, either directly if the tank has no air intake, or via a dip tube extending the pump if the tank has an air intake. In both cases, the product enters centrally into the pump. This is called centralized suction.
  • This type of central suction has a high suction speed since the product enters directly into the pump without pressure loss.
  • the document WO2017/125590 shows a liquid product dispenser comprising a reservoir equipped with a pump and a liquid suction device according to the preamble of claim 1.
  • the documents US 5,548,943 , US 2010/221132 And US 2010/252136 also disclose dispensing devices according to the prior art.
  • the present invention aims to overcome the various drawbacks stated 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 in an annular manner, then in a centralized manner.
  • the product therefore follows a different path from that of the prior art. It is no longer directly sucked into the pump or into the tube connected to the pump in a centralized manner, but it is diverted into annular suction means which create a pressure drop before being sucked into the pump.
  • This pressure drop makes it possible to significantly reduce the suction speed of the product within the dispenser, and therefore 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 channel. centralized vacuum system.
  • the product will first pass through a first relatively large and annularly located inlet section, which forces it to take a turn in its path and therefore slow it down, while reducing the pressure of the product thanks to the large section, then through a second smaller and centrally located inlet section, which forces it to take an additional turn in its path with a reduction in the surplus section, which slows down its suction speed even more, and this in a progressive manner.
  • the suction is thus carried out in a clean manner inside the tank, and with a speed calibrated so that the flow of the product leaving the dispenser is sufficient to satisfy the consumer, while avoiding any 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 product suction device as described above.
  • This process is very advantageous since it allows the entire suction device to be molded at once, and therefore to obtain a single part, which allows a considerable saving of time in the manufacture of the device. It also allows the manufacture of the device to be simplified, compared to an assembly of two parts (lower part and upper part) which must then be equipped with expensive and complex fixing means to implement.
  • the upper part consists of a purge ring
  • the latter generally equips a liquid product dispenser without air intake.
  • This purge ring has a deformable sealing lip housed inside a protective part designed to be inserted inside the tank, the deformation of the lip when fitting the ring in the tank causing the air to be purged from the tank.
  • the idea is to systematically associate a protective part intended to protect the fragile lip of the purge ring, from its manufacture to its assembly in the distributor.
  • the purge ring is used to purge the residual air present in the tank when the dispenser is assembled.
  • the purge ring is activated only when the dispenser is assembled, so that it can be put into service without any air intake.
  • the purge ring no longer intervenes 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 dispensers 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 bottle-type reservoir.
  • This reservoir may or may not contain a piston, or any other system allowing the dispenser to operate without air intake.
  • Such a dispenser head may include residual air when assembled on the tank during the packaging operation. This residual air may cause disruptions in the use of the product to be dispensed.
  • a flexible purge ring 1 is added to the distribution head, and allows the air purge function to be ensured, before normal use of the distributor.
  • This purge ring 1 is fixed to the neck 2 of the distribution head.
  • This lip 12 is generally made with a flexible material, for example low density polyethylene, or 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 internal wall of the tank.
  • the purge ring 1 also includes an axial sleeve 13 centered on the cap 11 and defining a centralized suction channel 8, opening onto an orifice 14 made in the cap 11.
  • This orifice 14 consists of the inlet of the centralized suction channel 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 projects into the lower part of the dispensing head.
  • the lip 12 is separated from the neck 2 by a gap e. The lip 12 is thus exposed, without any protection around it, and may be damaged during bulk storage of the dispensing heads thus equipped with rings 1.
  • the ring When mounting this distribution 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 complete, 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 on the dispensing head.
  • the product contained in the tank then undergoes suction and passes through the inlet 14 of the centralized suction channel 8, then through the centralized suction channel 8 of the socket 13, then into the pump 5 to be brought to the push button 4 and escape from the dispenser.
  • the product present in the tank thus enters directly into the centralized suction channel 8, along the X axis.
  • the suction speed is relatively high since there is no obstacle in the path of the product, apart from the inlet section of the centralized distribution channel which limits the quantity of product taken when the push button 4 is pressed.
  • this suction which suddenly causes the product 7 to pass from the static state to 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.
  • FIG. 2 shows a disclosed but unclaimed distribution head. It is analogous to that of the figure 1 for elements which bear the same reference, with the exception of neck 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 neck 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 the lower part of the pump 5 is inserted.
  • This neck 2 also conventionally comprises an annular return 22 directed towards the push button 4 and allowing the centering and wedging of the covering hoop 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 to bear against the internal wall of this peripheral skirt 24, just like the embodiment described in the figure 1 .
  • the ring 1 itself still has a cap 11 of truncated cone shape, but with a much more obtuse angle, allowing a significant reduction in 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 arching, with the internal wall of the peripheral skirt 24 of the neck 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 the event 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 part for the ring 1.
  • This tank 6 can be flexible or rigid, contain a piston (or another system) or not to follow the variability of the volume of product 7.
  • This part 9 is a part 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 zone from which the sleeve 13 projects. This bulge gives a slightly rounded shape to the cap 11 in this central part.
  • the part 9 follows this rounded profile, and consists more precisely of a bowl.
  • Part 9 has no holes.
  • the product must therefore go around part 9, take a first tight turn to be able to enter the annular passage 16, then take a second tight turn to be able to enter the centralized suction channel 8. This path significantly slows down the suction speed of the product. This is no longer a centralized suction, but an annular suction.
  • the inlet section of the annular passage 16 is greater than the inlet section 14 of the centralized suction channel 8. This progressive reduction in the suction section, as the product travels, makes it possible to obtain a less violent, more fluid suction, so as not to jolt the product and so that it retains its stability.
  • the suction device finally consists of a body composed of an upper part consisting of the ring 1, and a lower part consisting of the part 9.
  • the entrance of the annular passage 16 is located at the peripheral periphery 93 of the part 9.
  • the rings 1 and the part 9 are molded in a single mold.
  • such molding poses a demolding difficulty at the annular passage 16, because the bowl-shaped part 9 prevents access to the inside of the annular passage 16 in order to be able to demold this area correctly.
  • the bowl-shaped part 9 is cast with a concave curvature, in order to completely clear the area of the annular passage, as shown in 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 opening zones 92 for the passage of the product towards 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 rolling up of the part 9.
  • the body making up the suction device is thus manufactured in only two stages, that is to say a stage of molding its upper 1 and lower 9 parts, and a stage of turning over its lower 9 part.
  • ribs 17 are provided on the lower surface of the cap 11 of the ring 1, and are distributed regularly. 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 makes it possible 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.
