Definitions

  • the invention relates to the technical field of packaging a product intended to be dispensed in unit doses using a manual pump.
  • a more specific subject of the invention is a device for packaging and dispensing a product, comprising a rigid external container with an open neck, a deformable internal container with an open neck, this internal container being essentially housed in the external container and intended to contain the product to be packaged and dispensed, and a manual pump, of the type without air entering the internal container, this pump being intended to distribute the product in unit doses and being mounted in a sealed manner on the neck of the internal container at using sealing means.
  • Packaging devices of more conventional structure comprising a single container on which is fitted a manual pump dispensing the product contained in the container.
  • a pump generally comprises a pusher, making it possible, by pressing the finger of the user, to move a piston in a pumping chamber, the volume of which determines the dose to be dispensed.
  • a first closed valve isolates this chamber from the internal volume of the container, when the product is expelled from this chamber by a second open valve, under the effect of the displacement of the piston by pressing on the pusher.
  • the second valve closes and isolates the chamber from the outside, when this chamber fills with the first valve opened with a dose of product from the container, and drawn into the chamber by the return of the piston to its initial position, pressing against a stopper of a pump body in which the piston slides, and under the action of elastic return means.
  • This suction of the product causes a depression in the container.
  • packaging and distribution devices of the type presented above, to which the invention relates, and comprising a deformable internal container, containing the product. to be packaged and distributed and placed in a rigid external container, as well as a pump without air intake.
  • a dose of product is expelled from the deformable container, the vacuum created contracts the latter, around which the rigid external container provides mechanical protection for the internal container. But for such a device to work, it is necessary that the deformable internal container can retract.
  • This air intake is generally provided by at least one passage in the bottom of the rigid container, but the air intake can also be carried out around the neck of this rigid container.
  • deformable internal container generally made of plastic
  • the deformable internal container must have a small wall thickness in order to be able to easily deform, and that this results in significant permeability of its wall. , and a migration of part of the product and / or an evaporation of at least one volatile component of the product to be distributed through this flexible and thin wall of the deformable container.
  • This phenomenon is particularly noticeable with aqueous, alcoholic and / or products containing one or more volatile materials.
  • a gas given off by the conditioned product or a vapor resulting from the evaporation of a volatile phase of this product can pass through the thin wall of the deformable container and escape towards the outside through the passage reserved for the air intake .
  • deformable containers have been proposed made of relatively impermeable flexible composite materials.
  • Another solution already proposed to this problem consists in providing a non-return or unidirectional valve, placed in the passage or downstream from the passage provided for the air intake.
  • Such a valve allows air to enter the volume between the two containers, when the suction due to the return of the pump piston to its rest position requires it, but prevents the outflow of gas and / or vapor, the presence in the volume between the two containers results from the evaporation and the passage of volatile phase (s) of the product contained in the deformable container through the thin wall of this container. Thus, the evaporation of the product and its migration to the volume between the two containers cease as soon as this volume reaches saturation.
  • non-return valves requires the manufacture and assembly of at least one additional part to produce this valve, which significantly increases the cost of the device.
  • the main object of the invention is to provide a device of the aforementioned type, for which there is no fear of slackening or any other failure of the means for fixing the pump to the containers, nor of concomitant or independent deterioration of the seal between the pump and the internal container, while giving the device a simple structure, of economical manufacture.
  • a second object of the invention is to remedy a drawback stated above, by proposing a structure for a packaging and distribution device that does not require additional parts to produce a non-return valve allowing the entry of outside air. in the volume between the two containers and opposing the exit of gas or vapor from this volume.

  • the ring comprises, at its periphery internal, an internal tubular part, having said second fixing means, and in which is engaged said tubular part of the pump body, which has said complementary fixing means, said annular seal being mounted between said internal tubular part of the ring and said tubular part of the pump body, so that the seal can move axially between said tubular parts without this affecting the seal it provides.
  • the attachment of the pump to the intermediate ring thus has no influence on the seal, and vice versa.
  • the ring advantageously comprises, at its external periphery, an external tubular part having said first fixing means and engaged in said neck of the external container, of which said complementary fixing means are provided with projections and / or recesses having complementary forms of coupling to said first ring fixing means.
  • the second object of the invention namely the admission of outside air into the volume between the containers, without non-return valve, and by opposing the exit from this volume of any gas or vapor coming from the product conditioned and having migrated through the wall of the internal container, is reached by the fact that the external container is closed bottom and at least one of said ring and said necks delimits at least partially, outside said means d sealing, at least a first air inlet passage in the volume delimited between the two containers, and the pump body has, also outside said sealing means, at least a second inlet passage d air in said volume between the containers, so that said first and second air inlet passages define in succession a duct allowing air entry outside in the volume between the containers at least when the pump is actuated, and the device further comprises means for confining any part of the product passing through the deformable wall of the internal container from the internal volume of the latter towards the volume between the containers , and tending to escape to the outside through the air inlet duct, at least when the pump is not actuated.
  • the first air inlet passage is formed, between the external periphery of the ring and the neck of the external container, by said first ring fixing means and said fixing means complementary to the neck of the outer container, and using at least one recess in said ring and / or in said neck of the outer container.

  • the release of the pusher 37 causes , under the action of the return spring 47, and as described above, the closing of the outlet valve 40, the return of the piston 37 to the initial position and the opening of the inlet valve 18, for the admission of a new dose of product in room 36.
  • FIG. 5 shows the dispenser, the pump 11 of which is at rest, after at least one operation of the pusher 13, so that the chamber 36 contains a dose of product.
  • the two valves 18 and 40 are closed, as is the air inlet circuit in the intermediate volume 35, by the annular part 37b of the piston 37 which abuts against the annular bottom 28 of the internal jacket 22.
  • FIG. 6 represents the dispenser, during the dispensing of a dose of product, the pusher 13 being depressed by a manual action of the user, indicated by the arrow F1 the outlet valve 40 being open and the inlet valve 18 closed, the piston 37 being pressed into the cylinder 14, so that the product from the chamber 36 is expelled by the distribution tube 45, as indicated by the arrows F2.
  • the flexible bag 1 of the assembly of FIG. 2 is filled with product before the assembly of the pump of FIG. 3 on the assembly of FIG. 2 by elastic snap-fitting of the pump body 12 by its tubular part. 20 in the internal tubular part 6 of the ring 4 of this assembly.
  • This snap-fitting is ensured by the axial passage of the redent 20b beyond the redent 6a, the seal being ensured by the seal 21 between the pump body 12 and the ring 4.
  • a certain evaporation of a volatile phase of the product, or even a certain migration of part of the product can be carried out through the thin wall of the body of the flexible bag 1.
  • This evaporation and / or migration due to the permeability of the thin plastic material constituting this wall, causes an accumulation of vapor and / or gas, or even product, in the volume 35 between the receptacles 1 and 9, and causes an increase in pressure there.
  • gases and / or vapors tend to take the opposite path to that taken by the outside air, when a depression is created in this same volume 35.
  • annular part 37b of the piston 37 and the annular bottom 28 of the internal jacket 22 thus constitute means for confining the gases and / or vapors which could accumulate in the volume 35 between the containers 1 and 9, since this volume does not is not in permanent communication with the outside of the pump 11, due to the presence of these confinement means on the air inlet path, which however allow the entry of outside air into this intermediate volume 35 from that the pump 11 is actuated, to compensate for the vacuum created in this volume 35 by the operation of the pump 11.
  • a packaging and distribution device is thus produced in which the permeability of the wall of the deformable container 1 no longer poses a problem, since the migration and / or evaporation of part of the product contained in this deformable container 1 is stopped. when saturation is reached in the intermediate volume 35 between the two containers 1 and 9.
  • a simple remedy to this problem consists in introducing into the volume 35 , during the installation of the assembly of the flexible bag 1 and the ring 4 in the rigid bottle 9, a substance or a chemical body capable of fixing or absorbing this gas or this vapor.
  • the cylinder 14 and the internal jacket 22 may be one and the same piece, without axial channel air 32, and the volume 35 between the two containers 1 and 9 can be vented by an air inlet provided by a hole in the bottom of the container 9, or by a hole in the outer jacket 23 or in the part of the skirt 26 which is not fitted into the neck 10 of the container 9.
