Definitions

  • the present invention relates to a device for packaging and distribution of at least one fluid product.
  • the pump comprises means forming a suction valve and means forming a discharge valve, respectively upstream and in downstream of the pumping chamber.
  • the pressure necessary to expel the product outside the device is obtained by means of a control rod mobile in the pumping chamber.
  • a dispensing tip such as a push button fitted with a nozzle is fixed on the control rod before filling the tank.
  • control rod sinks into the pump body and decreases the volume of the pumping chamber, causing the distribution of a predetermined amount of product.
  • the rod When the user releases the dispensing tip, the rod is returned to its initial position by a spring. This return movement of the control rod is accompanied by a increase in volume of the pumping chamber.
  • the means forming discharge valve are arranged to prevent the return of the product contained in the dispensing nozzle to the pumping chamber as well than an air intake.
  • the means forming a suction valve open during the ascent phase of the control rod to allow the product contained in the tank to be sucked into the chamber pumping.
  • the tank can consist of a flexible pocket deformable which shrinks as the product is distributed or, alternatively, be formed by a cylindrical wall provided a movable bottom constituted for example by a piston which can slide inside it or alternatively by a membrane which deforms to occupy inside the tank the space left by the product that has been distributed.
  • the filling of the tank can be carried out by a vacuum filling process consisting of create a depression in the tank then put this tank in communication with the product source so that the product is located sucked.
  • Such a filling process presents in particular the advantages of enabling a high production rate and avoiding oxidation of the product on contact with air.
  • the mounting of the dispensing nozzle on the control rod is carried out by forcibly engaging the control rod in a housing adapted from the dispensing nozzle, and is accompanied by a depression of the control rod in the pump body until the control rod comes to the end of the driving stroke.
  • Tests have shown that when the tip of the distribution on the control rod after vacuum filling of the tank, pushing in the control rod caused expulsion a certain amount of product, causing soiling and risking further degradation in contact with the air of the product contained in the outlet channel of the dispensing nozzle, or even the clogging of this outlet channel after drying of the product.
  • the present invention aims in particular to allow the mounting of the dispensing nozzle on the control rod (s) of the pumps after vacuum filling of the tank (s), without the disadvantages mentioned above.
  • the packaging and distribution according to the invention comprises means forming an anti-vacuum valve, arranged to isolate the chamber from pumping of the pump (s) from inside the tank (s) associated when a vacuum is created in this or these for the filling.
  • the vacuum is not created in the pumping chamber during the suction of the air initially present in the associated tank so that when the latter is put in communication with the product source, it only fulfills the tank and not the pumping chamber.
  • the dispensing tip therefore remains substantially free of product during storage and avoid all risk of soiling, degradation or drying of the product.
  • the invention makes it possible to avoid the distribution unexpected dose of product when fitting the tip distribution on the control rod (s).
  • the invention makes it possible in particular to mount two pumps equipped each of a reservoir constituted by a flexible pocket inside of a case then to bring on this case a cover used to both at the actuation of the pump control rods and at the distribution of the mixture of products contained in the tanks.
  • the invention is also of interest when the tip of distribution is already fixed on a control rod before the filling the tank.
  • the means forming a suction valve consist of a ball, which therefore does not seal that when the pump is used in a predetermined position, head up for example.
  • the means forming an anti-vacuum valve according to the invention are of preferably capable of ensuring a watertight closure in any which position, which increases the possibilities of using the pump.
  • the means forming a valve anti-vacuum are an integral part of the pump and also act as suction valve, allowing the product contained in the tank to be sucked into the pumping chamber while preventing its return when the control rod is pressed.
  • valve means anti-vacuum are reported on the pump, which is manufactured separately and can be constituted by a pump known identically or having no undergone only minor and inexpensive modifications.
  • This pump is for example a pump of the type comprising a valve constituted by a ball and / or a control rod recalled by a spring.
  • the means forming an anti-vacuum valve have a support piece attached to the tank and on which is attached to the pump.
  • the means forming an anti-vacuum valve are integral with the tank.
  • FIG. 1 shows a device 1 for packaging and distribution according to the prior art.
  • This device 1 comprises a reservoir constituted by a container 2 with cylindrical wall, provided with a movable bottom constituted by a piston 3 sliding tightly inside the wall 2.
  • the container 2 has at its upper part a neck 4 on which is attached a pump 5 which is shown in section on the figure 2.
  • This pump 5 comprises a body 6 formed by the snap-fit assembly of an upper part 6 a and a lower part 6 b .
  • a control rod 8 is slidably mounted at its lower part in the body 6 against the action of a return spring 9 working in compression, one end of this spring 9 bearing against a shoulder 10 at the bottom of the lower part 6 b of the body 6 and the other end bearing against a shoulder 8 a of a nozzle 8 e fixed to the lower end of the control rod 8.
  • the upper part 6 a has a flange 18 used for mounting the pump 5 and a seal 14 located under this flange allows a tight fixing on the container, by means of a metal ring 7 crimpable on the neck 4 of the container 2.
  • the control rod 8 is traversed by an axial recess 8 d extending above the nozzle 8 e to its upper end.
  • a dispensing nozzle 19 serving both as an organ actuation and nozzle is force fitted on the end upper of control rod 8.
  • a piston 11 is mounted around the control rod 8 inside the lower part 6b of the body 6.
  • This piston 11 slides both in contact with the lower part 6 b and in contact with the control rod 8 and has an internal shoulder 11 a against which abuts a shoulder 8 b of the control rod 8 after a slight stroke d sinking of the latter.
  • the piston 11 has in the lower part a skirt 11 b against which the end piece 8 e of the control rod 8 bears when it is at rest, that is to say when it comes into abutment with a shoulder 8 f located above the piston 11 against a constriction 17 of the upper part 6 a .
  • the control rod 8 has radial holes 8 c communicating with the axial recess 8 d at its lower end and making it possible to convey the product to the dispensing nozzle 19.
  • the lower part 6 b serves as a seat for a ball 13 closing at rest an orifice 26.
  • the piston 11 and the ball 13 delimit a pumping 12 inside the body 6.
  • the control rod 8 therefore moves relative to the piston 11 and the end piece 8 e ceases to be supported on the skirt 11 b .
  • the holes 8 c then communicate with the pumping chamber 12 through the gap existing between the control rod 8 and the lower edge of the skirt 11 b .
  • the product is then expelled from the pumping chamber 12 by the movement of the piston 11 and gains the axial recess 8 d by the holes 8 c , to be dispensed.
  • the ball 13 remains in abutment against its seat in the bottom of the lower part 6b of the body 6 and prevents the product from being pushed back into the tank.
  • control rod 8 slides first in the piston 11 until it comes to bear by the end piece 8 e against the lower edge of the skirt 11 b .
  • the axial recess 8 d is then isolated from the pumping chamber 12, and the continued upward movement of the control rod 8 under the action of the spring 9 causes a vacuum in the pumping chamber 12, which is accompanied the lifting of the ball 13 and the arrival of product from the reservoir.
  • the inventors have found that with known pumps, if the vacuum is created in the tank before filling, the ball 13 does not ensure a sufficiently tight closure of the chamber pumping 12, so that the air present therein is sucked.
  • the invention overcomes this drawback.
  • FIG. 3 in schematic axial section, a first embodiment of a pump according to the invention, which has the reference 22 and differs from the pump 5 previously described in that the lower part of the body of the pump, referenced here 6 b ′, has an external annular groove 28 and by the fact that it is provided with an anti-vacuum valve 23 secured to a support piece 24, which is fixed by snap-fastening in the groove 28.
  • the vacuum valve 23 is specially designed to prevent the air initially present in the pumping chamber 12 is sucked when the tank is placed under vacuum for filling.
  • the anti-vacuum valve 23 is produced, in the example described, by elastomeric material, being overmolded on the support piece 24 or in variant made by bi-injection therewith.
  • the support piece 24 is pierced with an orifice 25 closed at rest by the anti-vacuum valve 23 and allowing the product to gain the orifice 26 when the control rod 8 rises.
  • the orifice 25 is closed with the necessary seal by the valve 23, even when the tank is upside down and put on in depression.
  • the container 2 is arranged upside down, then the head T of a vacuum filler is applied tightly against the bottom of the container 2.
  • the air is then sucked into it through a channel of the head T.
  • valve 23 is firmly pressed against its seat on the workpiece support 24 and prevents the air contained in the pumping chamber 12 from escape.
  • the vacuum created in container 2 is only relative, and it it is sufficient in accordance with the invention that the filling takes place under a pressure below atmospheric pressure.
  • the interior of the container 2 is placed in communication with a source of product P, and the latter gains, via the head T, the interior of the container, as illustrated in figure 5.
  • the anti-vacuum valve 23 is attached to the pump, which does not differ from the pumps known only by a minor modification, namely the presence throat 28.
  • the anti-vacuum valve, referenced 30, is an integral part of the pump, being molded onto the body of the latter, referenced 31, or made by bi-injection with it.
  • the anti-vacuum valve 30 replaces the ball 13 of the pump 5 previously described and allows a better seal than this vis-à-vis the vacuum created in the tank prior to its filling.
  • the pump is similar for the rest.
  • valve 30 operates from the same way as ball 13 by allowing the product to gain the pumping chamber 12 when raising the control rod and prevent the product from being returned to the tank when the user presses on the dispensing nozzle 19.
