Definitions

  • the present invention relates to the technical field of packaging, and more particularly to that of packaging a product intended to be dispensed in unit doses using a manual pump.
  • the invention more particularly relates to a device for packaging and dispensing in unit doses, and which comprises a rigid external container, in which is housed at least the major part of a deformable internal container, intended to contain the product to be dispensed , in unit doses, using a manual pump of the type without air inlet, which is mounted on the open necks of the two containers.
  • Packaging devices of conventional structure comprising a container on which is fitted a manual pump dispensing the product contained in the container.
  • a pump generally comprises a pusher, allowing, by simple pressure of the user's finger, to cause the displacement of a piston in a pumping chamber, the volume of which determines the dose to be dispensed.
  • a first valve makes it possible to isolate this chamber from the internal volume of the container, when the product is expelled from this chamber by a second valve, under the effect of the displacement of the piston by pressing on the pusher, and the second valve allows to isolate the chamber from the outside, when this chamber is filled with the first valve with a dose of product from the interior of the container, and drawn into the chamber by the return of the piston to its initial position, pressing against a stop a pump body in which the piston slides, and under the action of elastic return means.
  • This suction of the product causes a vacuum inside the container.
  • packaging and distribution devices comprising a pump without air inlet, as well as a deformable container, which contains the product to be conditioned. and distribute.
  • a deformable container which contains the product to be conditioned. and distribute.
  • the vacuum created contracts this deformable container, around which a rigid external container has been provided to provide mechanical protection for the internal deformable container. But for a device thus produced to work, it is necessary that the deformable internal container can retract.
  • This air inlet is generally provided in the bottom of the rigid container, in which a passage is arranged for this purpose, but the air inlet can also be made around the neck of this rigid container.
  • the major drawback of this type of packaging device is that the deformable internal container, which is made of plastic, must have a small wall thickness in order to be able to easily deform, and that this results in significant permeability. of the wall of the deformable container, 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 wall of the deformable container.
  • This phenomenon is particularly noticeable with aqueous, alcoholic products and / or with those 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 to 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 of the passage intended for the air intake.
  • Such a valve allows passage only in one direction, and it lets air enter the volume between the two containers, when the suction due to the return of the pump piston to its rest position, pressing against a stop of the pump body, requires it, but prevents the outflow of gas and / or vapor, the presence of which in the volume between the two containers results from evaporation and the passage of volatile phase (s) of the product contained in the container deformable through the thin wall of this container.
  • non-return valves of this type requires the manufacture and assembly of at least one additional part to produce this valve, which significantly increases the cost of the device.
  • a second drawback of this type of packaging device comprising a manual pump without air inlet adapted to a set of two containers, one of which is deformable internal and one rigid external, lies in the cost of manufacturing the deformable container.
  • a first object of the invention is to remedy the main 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.
  • a second object of the invention is to allow the manufacture of deformable containers with a thin wall by the plastic injection technique, by proposing, in particular for this purpose, special wall shapes which make it possible to use this technique, and which also have the advantage of allowing the easy introduction of the deformable container inside the rigid container, as well as the possibility of completely emptying the deformable container of the product which it contains, in packaging and dispensing devices with manual pump according to the invention and as presented above.
  • a device for packaging and distributing a product comprising a rigid external container, with open neck, a deformable internal container, with open neck and which is essentially housed in the external container, and intended to contain a product to be packaged and dispensed, and a manual pump of the type without air entering the internal container and intended to distribute the product in unit doses, and which is mounted on the neck of the outer container and tightly on the neck of the internal container using sealing means, the device being characterized in that the external container is closed bottom, the internal container has its neck more rigid than its deformable body, and at least one of the necks delimits the at least partially, outside the sealing means at least one passage and / or air inlet orifice in the volume delimited between the two containers, and the pump comprises a body mounted on the necks of the containers and having, outside the sealing means, at least one air inlet orifice in the volume between the two containers, so that said air inlet passages and orifices define in succession
  • the air inlet passages and orifices of the external and internal containers and of the pump are in permanent communication with each other, so that the air inlet duct is permanently open, and the confinement means comprise a sealed cover, which is removably and sealed attached to the device, around the pump and the necks of the containers, and the air inlet duct opens out inside the cover when the latter is fixed to the device.
  • a cover which such a device generally comprises, so that no additional part is necessary.
  • the air inlet passages and orifices of the external and internal receptacles and of the pump are in permanent communication with each other, so that the air intake duct is permanently open, but the confinement means comprise the stop, which has an annular and conical end, forming a sealed seat, in contact with a peripheral conical part of the piston, in the pump rest position, the stop delimiting with the pump body at least one passage allowing air to pass from the outside of the device to the ent duct air flow, as soon as the piston is moved away from the conical end of the stop, when the pump is actuated.
  • the sealing means for mounting the pump on the neck of the internal container comprise an annular seal, surrounding the pump body and retained between the latter and this neck
  • the air inlet orifice of the internal container which crosses the neck of the latter outside the seal, or in permanent communication, on the one hand, with the passage of air inlet of the external container (passing through its neck), and, on the other hand, with an annular space, delimited between the pump body and the neck of the internal container, and into which the inlet opening of air from the pump body, and the confinement means comprise the annular seal, which is elastic and substantially flat, and has at least one part extending in said annular space and forming a non-return valve, by applying elastically against the pump body in positio n obturation of its air inlet orifice when the pump is not in the pumping phase of a dose of product out of the internal volume of the internal container, while the seal flexes elastically towards the inside the annular space
  • the outside air can enter the volume between the two containers passing through the air inlet orifice formed in the pump body, and pushing the seal forming a valve, but the gases and vapors cannot escape in the other direction, because their pressure causes the air inlet port of the pump to close by applying a seal against this port, or adds its effects to the elasticity clean the seal to return to the closed position of the pump body air inlet.
  • this volume being an enclosed space, by the gasket forming a valve, or extended by an enclosed space delimited by the cover or by the cooperation of the pump piston and its stop, depending on the variants, and only the outside air capable of penetrate into this volume between the containers, while no gas and no vapor can exit therefrom to the outside, it is further advantageous that this volume between the containers contains at least one chemical body or a substance capable of fixing a gas and / or a vapor contained in the outside air admitted into this volume, to avoid the diffusion of this gas or this vapor through the wall of the internal container and towards the product in the interior volume of this latest.
  • this chemical body can fix the oxygen in the air or the water vapor contained in the outside air, the diffusion of which towards the interior of the deformable container, through the wall of this the latter, would have the effect of degrading products sensitive to oxidation or humidity.
  • the second object of the invention namely the use of special wall shapes allowing the plastic injection technique to be used for the manufacture of deformable containers, is achieved by the fact that the internal container, made of plastic material , is of generally cylindrical shape with a closed bottom at an end opposite to that arranged in an open neck extending its deformable body with a thin wall provided with longitudinal ribs projecting inwards, and of progressively decreasing thickness and / or width (s ) from the bottom to the neck.
  • This structure of the deformable container with thin wall allows the demolding of the internal part and the shape of the longitudinal ribs promotes the passage of the molten plastic during the injection of the part. So, he It is possible to mold containers with a very thin wall, and easily deformable, without using a high injection pressure.
  • the raised ribs make it possible to obtain that different parts of the wall of the deformable container do not stick against each other, and do not trap a portion of the product in a space that it would not be possible to drain.
  • the cylindrical shape of the deformable container with a thin and flexible wall allows it to be introduced easily and without deformation into the rigid external container which protects it.
  • the external container is also made of plastic and of generally cylindrical shape, and the rigid wall of its body is provided with longitudinal grooves formed in its internal face, and one of which at least extends, from the neck towards the bottom of this container, at least one groove forming an air inlet passage in the neck of the rigid container.
  • This structure of the external container is advantageous in that it makes it possible to mold it by injection, without significantly increasing its thickness.
  • the two containers can be assembled in the factory, and to prevent them from separating during transport, it is provided that the necks of the external and internal containers are provided with projections and / or depressions having complementary shapes.
  • the packaging and distribution device comprises an internal and deformable container 1, the body of which has a flexible wall made of thin plastic, and which is mounted in a rigid external container 2, a pump 15 , of the type without air intake, being assembled on the open necks 17 and 16 of the receptacles 1 and 2 respectively.
  • This pump 15 comprises a body 13 having a cylindrical central part, in which a piston 6 slides, having a central chimney by which the piston 6 is moved by a pusher 5 provided with a distribution channel 24.
  • a first valve 8 cooperates with a seat around the central opening in the bottom 13a of the central part of the body 13, to isolate the interior volume of the chamber 7, delimited between the piston 6 and the bottom 13a of the body 13, from the interior volume 11 of the deformable container 1.
  • a second valve 9 cooperates with a seat formed around the central opening of an annular stop, provided in the chimney of the piston 6 to serve as a stop for a return spring 10, so that the second valve 9 can isolate the chamber 7 from the outside, through the internal channels of the pusher 5.
  • the spring 10, extending in the chamber 7 between the two valves 8 and 9, recalls the piston 6 in the rest position, against a stop projecting radiallytowards the inside of the cylindrical part of the body 13.
  • This cylindrical part of the body 13 is engaged inside the open neck 17, more rigid than the body of the deformable container 1, and an annular seal 4 is mounted around the pump body 13 and between a folded rim of this last and the neck 17 of the inner container 1, which neck 17 is applied inside and against the upper face of the neck 16 of the rigid container 2.
  • the seal between the body 13 of the pump 15 and the neck 17 of the deformable container 1 is thus ensured by the seal 4.
  • the folded rim of the body 13 is provided with a recess 14, projecting towards the inside of the body 13, and allowing the attachment of the body 13 on a corresponding recess on the neck 16 of the outer container 2, and projecting outwards from the latter.
  • FIG. 2 This mounting of the pump 15 on the necks 16 and 17 of the containers 2 and 1 appears in more detail in FIG. 2, which also shows an orifice 18 formed in the edge of the body 13, and in permanent communication with a volume annular 19, delimited between the rim of the body 13 and the neck 17 of the deformable container 1, to accommodate the seal 4.
  • This annular volume 19 is itself in permanent communication with an orifice 20 formed in the neck 17 of the container deformable 1, radially outside the seal 4, like the orifice 18 of the body 13.
  • This orifice 20 opens into grooves 21 formed, for example axially or longitudinally, in the neck 16 of the rigid container 2, and themselves in permanent communication with the volume 12 delimited between the two containers 1 and 2.
  • the orifice 18, the volume 19, the orifice 20 and the grooves 21 delimit, in succession or in continuity, an air intake duct, permanently open between the exterior of the pump 15 and of the containers 1 and 2, and the volume 12 delimited between these containers 1 and 2.
  • a sealed cover 3 is fixed in a removable and sealed manner, for example by elastic interlocking, around the pump 15 and the necks 16 and 17 of the containers 1 and 2.
  • the device operates as follows: the cover 3 of the pump 15 being removed, manual pressure, exerted by the user on the pusher 5, successively opens the valve 9 by a rod central pusher 5 then moves the piston 6 against the spring 10 towards the bottom 13a of the body 13, which allows the product contained in the chamber 7 to escape towards the outside via the central chimney of the piston 6 then the channel 24 of the pusher 5, while simultaneously, the valve 8 is closed, which prevents any backflow of the product contained in the chamber 7 towards the interior 11 of the deformable container 1.
  • a dose of the product is thus distributed to the outside.
  • the spring 10 returns the piston 6 to its initial rest position, pressing against the stop in the body 13, and the upper valve 9 closes, which prevents any entry of outside air into the chamber 7, and, on the contrary and simultaneously the lower valve 8 opens, which allows a new dose of product to enter the chamber 7 from the internal volume 11 of the internal container 1.
  • a certain evaporation of a volatile phase of the product, or even a certain migration of part of the product can be carried out at through the thin wall of the body of the deformable container 1.
  • This evaporation and / or migration due to the permeability of the thin plastic material constituting this wall, causes an accumulation of vapors and / or gases, or even of product, in the volume 12 between the receptacles 1 and 2, and causes an increase in pressure there.
  • the cover 3 thus constitutes a means of confining the gases and / or vapors which could accumulate in the volume 12 between the containers 1 and 2, since this volume 12 is in permanent communication with the interior of the cover 3, mounted on the device, by the air inlet duct formed by the orifices and passage 18, 19, 20 and 21.
  • the stop of the body 13 of the pump 15, against which the spring 10 recalls the piston 6, when the pump is not actuated is a part 27 comprising a cylindrical part engaged in the body 13 and a radial annular part, and this part 27 is made integral with the body 13 by clamping in the latter.
  • This stop 27 has, in its cylindrical part, longitudinal or axial grooves 28, in its face facing the body 13, and this part of the stop 27 ends, on the side of the piston 6, by an annular end 29 of conical shape.
  • the end of the grooves 28 which is opposite the conical end 29, is in permanent communication with a volume 31, delimited between the rim of the body 13 and the annular radial part of the stop 27, and into which opens the orifice 18 formed in the body 13 and in permanent communication, as in the previous example, with the annular volume 19 for housing the seal 4, the orifice 20 passing through the neck 17 of the deformable container 1 and the grooves 21 forming a passage d 'Entrance in the neck 16 of the rigid container 2, thereby delimiting a permanently open air intake duct opening into the volume 12 between the containers 1 and 2.
  • the piston 6 is not in contact with the stop 27, the lower end of the grooves 28 is not blocked, and the outside air can pass through the passage delimited by the grooves 28, the volume 31 and the air intake duct 18-19-20-21 to penetrate into the volume 12 and compensate the vacuum created in this volume by the operation of the pump 15.
  • the orifice 18 in the body 13 of the pump 15 is not in direct relation with the annular space 19 housing the seal 4, but is separated from the space 19 by a part of this seal 4, which is annular, elastic and flat, and which is applied by its natural elasticity against the body 13 by sealing the orifice 18.
  • the space 19 is in permanent communication with the orifice 20 in the neck 17 of the deformable container 1, the orifice 20 itself being in permanent communication with the grooves 21, formed in the neck 16 of the rigid container 2, to open into volume 12 between containers 1 and 2.
  • the seal 4 acts as a non-return valve, and allows the passage of air from the outside to the volume 12, but prevents the escape of vapors and / or gases to the exterior, from this volume 12, even in the absence of the cover 3. It is also not essential to provide a stop such as 27 in FIG. 3.
  • the stop limiting the movement of the piston 6 can be as shown in Figure 2.
  • 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 the internal volume 11 of the deformable container 1 is stopped when saturation is reached in the volume 12 located between the receptacles 1 and 2.
  • a simple remedy to this problem consists in introducing into the volume 12, before placing the pump 15 on the necks 16 and 17 of the containers 1 and 2, a chemical substance or body capable of fixing or absorbing this gas or this vapor.
  • the seal 4 forming a non-return valve, prevents any exit of this substance or of this chemical body towards the outside of the device and also prevents any exchange with the outside. , likely to saturate this substance or chemical body absorbing oxygen or water vapor.
  • FIG. 5 represents, in axial section, an advantageous embodiment of the deformable container 1, to which a cylindrical shape has been given, in order to allow its manufacture with a flexible and thin wall of its body, by molding according to the injection technique of plastic material.
  • the internal volume 11 of the deformable container 1 is obtained, in the molding tool, by a core whose cylindrical shape allows demolding without undercut.
  • the thin and flexible wall of the cylindrical body of the deformable container 1 has, on its internal face and projecting radially inwards, longitudinal ribs 22 which, on the one hand, facilitate passage plastic material during injection, from an injection point located at the closed bottom 23, opposite the neck 17 of this container 1, and which, on the other hand, allow the material plastic melted during injection more easily filling the massive part of the neck 17, and avoiding braking of this plastic material by the thickness of the wall of the cylindrical body of this deformable container 1.
  • These ribs 22 have a progressively decreasing width and thickness from the closed bottom 23, at the injection point, and in the direction of the neck 17, because the distance of travel remaining to be traveled by the plastic during the injection decreases when e this material is close to the neck 17.
  • FIG. 6 partially represents a preferred variant of the invention, in which the two containers 1 and 2 constitute an assembled assembly, the deformable container 1 being that of FIG. 5, in which the orifice 20 passing through its neck 17 is formed in the bottom of an annular shoulder 19 ′, delimiting the annular space 19 in an embodiment such as that of FIG. 4.

  • This configuration makes it possible to mold the rigid container 2 by the process of plastic injection, the particular shape of the projection 26, and of the grooves 21 and 21 ′ reducing the undercut part of the core in the mold and allowing easier release from the mold. .
  • the containers 1 and 2 can be hooked by their necks 16 and 17 by means of other embodiments of projections and / or recesses of complementary shapes, without thereby departing from the scope of the invention.
