  There is a need to obtain new packaging and application equipment with a relatively simple structure that allows products, which can be powders, liquids, gels or creams, to be easily loaded onto the application element.

  The packaging and application device according to the invention comprises a container having an interior space with the product therein, an application element, a storage for accommodating the application element and a space between the storage and the interior space for the product. It is of the type having an arranged permeation wall.

  The apparatus is such that the application element and the receptacle present at least one surface portion positioned opposite the opening of the permeation wall without significant axial compression when the application element is in the receptacle. Being arranged in a shape, and wherein said internal space has a variable volume, said internal volume of a first volume greater than the volume of the product to a second volume smaller than the first volume Compression means are provided for selective transfer, and this reduction in volume is accompanied by pressurization which can favor the transfer of the product through the permeation wall towards the application element. It is characterized by:

  Advantageously, the compression means are arranged in such a way that the internal space recovers its first volume under the action of an elastic restoring force.

  The elastic restoring force is obtained because the container is a shape memory container, preferably made of a plastic material.

  The elastic restoring force is likewise obtained using a spring, in particular a helical spring.

  The device according to the invention has a number of advantages.

  First, the presence of air in the container avoids consolidation of the product stock when the interior space occupies its second volume, unlike for example the device described in US Pat. It becomes possible.

  It should be noted that the device according to the present invention can store the product in the inner space of the container without having to have a perforated bottom surface capable of blowing air. It may be of a simpler configuration than that shown.

  Because there is no axial compression of the surface portion of the application element positioned opposite the infiltration wall, the product can easily traverse this infiltration wall when pressure is created.

  Advantageously, the device has holding means on and / or adjacent to the permeation wall on the side of the interior space containing the product, these holding means being in particular by capillary action or electrostatic attraction. , Which favors the retention of the product in or near the opening so as to transfer the product into the storage during compression of the air volume present in the interior space between the permeating wall and the product storage. ing.

  It is thus clear that the device can be placed head-up at the moment when pressure is created and / or at the moment when the application element is withdrawn from its storage, which facilitates its use.

  Moreover, it is possible to arrange the holding means in such a way as to control the distribution of the product, in particular while avoiding the excess product from reaching the storage of the application element in use.

  In one particular embodiment, the container is through a movable wall that allows the pressure to be generated.

  The movable wall may include a flexible wall of the container, such as a relatively inexpensive bellows-shaped flexible wall.

  In a variant, the movable wall may comprise a rigid wall of the piston.

  Compression means capable of creating pressurization contribute to the distribution of a predetermined amount of product in each use, while allowing the user to apply a predetermined pressurization within the interior space of the container each time. It can be arranged to be.

  Thus, the product can be more easily accumulated in the space formed between the permeation wall and the application element.

  In such a way as to facilitate the creation of such a space, the permeation wall has at least one rib on the side of the application element, which is to be supported by this rib.

  The permeation wall may likewise be connected to the container by a step forming a recess on the side of the application element.

  In a variant, the application element and the receiving part are arranged in such a way that, when the application element is in place in the receiving part, the surface of the application element serving to apply the product is in contact with the permeation wall. Be placed.

  The application element is arranged in such a way that its surface, which is located opposite the osmotic wall when it is in place in said receptacle, can recede into the container under the action of pressure. Good.

  Thus, this surface can be easily loaded with the product.

  In one particular embodiment, the receptacle is defined by a preferably solid side wall around which the application element is pressed.

  Preferably, the application element is pressed in an airtight manner on said side wall.

  The application element behaves like a piston during its retraction, for example over a stroke of 4 mm, and can create a negative pressure in its housing.

  Also in one particular embodiment, the container is arranged such that the product level in the container does not reach the permeation wall when the internal space occupies its second volume.

  Thus, if the product is a liquid, any danger of overflowing the product is avoided.

  In one particular embodiment, the osmotic wall constitutes a bottom surface of a housing for accommodating the application element, the application element being an opening positioned in the axis of the container on the side opposite said osmotic wall. Through the housing.

  Similarly, in one particular embodiment, the permeation wall has a cross-sectional area and length selected in such a way as to allow a predetermined amount of product to be stored and / or passed therethrough. Having a flow path having

  Thus, when the pressure is applied, the amount of the product that has reached the storage section can be measured.

  The application element may advantageously be integral with the capture element, which also constitutes the closure cap of the container.

  The trapping element can have a gas-tight means for ensuring a gas-tight closure of the housing containing the application element.

  The infiltration wall may be realized by molding with the container or one element thereof.

  In a variant, the osmotic wall may be constituted by parts retrofitted on the container.

  The application element may be internally non-porous.

  In one particular embodiment, the application element may be flocked or have fabric on its surface.

  The housing for housing the application element may be movable with respect to the interior space of the container containing the product.

  The device can have a second application element, a second housing and a second permeation wall.

  The second application element may be of the same nature as the first but of a different size.

  The first and second application elements need not be of the same nature.

  The container may have a neck closed at one end opposite the application element by a removable stopper.

  The product may be at least partially formed of particles containing at least one fluid, which fluid is for example encapsulated in microcapsules.

  Compositions containing such particles have the ability to adhere well, but not excessively, to the skin, and are very soft and easy to apply, exhibiting excellent cosmetic properties.

  When applied on a skin, the pressure exerted by the application element on the skin triggers the release of a liquid, which provides a refreshing and soft feel.

  Such compositions may have a powder phase comprising pigments and / or pearls and / or fillers and / or glitter and / or mixtures thereof.

  Said pigments are preferably lacquers such as titanium dioxide, zirconium dioxide or cerium dioxide, zinc oxide, iron oxide or chromium oxide, nanotitanium, nanozinc, pyrite, carbon black, calcium salts, barium salts, aluminum salts or zirconium salts.

  The device may include a one-way valve for re-entrapping air to allow the flow of air therein when there is a negative pressure in the container.

  Advantageously, when the volume of the internal space is equal to the first volume, the internal space is at atmospheric pressure.

The present invention further provides a method of loading a product onto a coating element, wherein the product is contained within an interior space of a container, the interior space having a substantial amount of air above the product. And

And a method comprising:

  The need to create a pressurization at the point of use makes it possible to realize this infiltration wall in such a way that the product does not easily cross the infiltration wall, for example under the action of gravity alone.

  Thus, for example, the risk of product spillage in the event of an accidental fall is reduced.

  In particular, the passage size of the permeation wall can be selected according to the rheological properties of the product, in particular its viscosity, in such a way that a sufficient amount of the product has to be exerted across the permeation wall. .

  Preferably, the interior of the vessel is at atmospheric pressure before the generation of said pressurization.

  Returning to the apparatus 10 again, it can be seen in FIG. 1 that the body 24a is closed at the bottom by a solid bottom wall 24b.

  The container 11 constitutes a single housing 14 intended to house an applicator 15 including a capture mechanism 17 and an application element 16 and has a neck 13 of axis X consisting of retrofit parts, This capturing mechanism also constitutes the cap of the neck 13.

  The cap 17 has an airtight skirt 18 which is pressed in an airtight manner on the inner surface of the neck 13.

  The cap 17 also has an external skirt 19 provided with threads for engaging over complementary threads 20 provided on the upper part with the external surface of the neck 13.

  A permeation wall 23 separates the storage from the internal space 12 containing the product P.

  The amount of product contained in the container 11 is selected such that a substantial amount of air is present above the product in the container.

  Thus, the interior space of the container for containing the product is initially filled, for example, by half or three quarters.

  In the described embodiment, the permeable wall 23 is realized in one piece by molding a plastics material with the neck 13.

  The infiltration wall 23 has an inner surface 30 facing the inner space 32 and an outer surface 31 that defines the bottom surface of the storage unit 14.

  In the example described, a plurality of openings 25 having a diameter in millimeters traverse the permeation wall 23 and these openings 25 are evenly distributed.

  The application element 16 is formed of a foam.

  The front surface 16a of the application element 16 located opposite the outer surface of the permeation wall 23 remains in contact with this permeation wall without significant axial compression.

  The lateral surface 16b of the application element 16 lies in a radially compressed state facing the side wall of the neck 13.

  The surface 16a can be retracted away from the wall 23 under the action of the pressure created in the container 11.

  The operation of the device 10 will now be described with reference to FIGS.

  Container 11 is assumed to be stored head down. That is, the product P is on the permeation wall 23 as illustrated in FIG.

  The user inverts the container 11 and compresses the flexible wall of the body 24a as shown in FIG. 13 to evacuate the interior space 12 containing the product, first at atmospheric pressure, from a first volume to a smaller volume. A transition is made to a second volume, thus creating a pressurization in this interior space 12.

  When the user releases the pressure, the internal space returns to its original or first volume due to the shape memory of the container.

  The product held by capillarity and / or electrostatic attraction on the side of the inner surface 30 of the permeation wall 23 and in the opening 25, as illustrated by the arrows in FIG. Under the action of pressure, it is driven into the housing 14 in contact with the application element 16.

  The applicator element 16 is thus loaded with the product, after which the applicator element can be pulled out for application with the product present on the front face 16a as illustrated in FIG.

  If the container 11 is not stored head-down, the user can shake the container to guide the product into contact with the inner wall 30 of the permeable wall.

  At this time, the product is deposited on the permeable wall 23, which can hold it by a certain amount by capillary action and / or electrostatic attraction.

  The pressure generated thereafter can favorably transfer the product from the inner wall 30 to the outer surface 37 for loading on the application element 16.

  In the example described here, the side surface 16 b of the application element 16 is pressed onto the side wall of the neck 13, so that a slight negative pressure is present in the housing 4 when the application element 16 is withdrawn. Will be produced.

  Pressurization can be created in the interior space containing the product by various means.

  By way of example, FIG. 2 shows a device 40 in which the product is contained in one container 41.

  The container has a deformable portion 42 in the form of a bellows, which connects an upper portion 43 and a lower portion 44 of the container.

  To create a pressurization in the interior space containing the product, the user is required to place the device head-down via the applicator capture element 45 on the support surface as illustrated. Press the upper part 43.

  FIG. 3 shows a device 50 in which a substantially non-deformable body 52 with a push button 54 connected by a bellows 53 on the upper part is contained in a container 51.

  This bellows may be made in one piece with the main body 52 or may be made up of retrofit parts.

  To exert pressure, the user presses the push button with the container 51 resting head-down via the applicator catching element 45, thus folding the bellows 53.

  The device 60 shown in FIG. 4 has a container 61 including a body 62 and a neck 63 connected to the body 62 by a deformable portion 64 in the form of a bellows.

  An insert 66, generally in the shape of a finger of a glove, is mounted in the neck 63 and forms a storage compartment 67 for the applicator 69.

  This applicator has a closing cap 69b which also constitutes an application element 69a and a capture element.

  The cap 69b has an internal airtight skirt 69C that can be pressed in an airtight manner onto the internal surface of the insert 66 to ensure an airtight closure of the container, the insert 66 itself being the upper part of the neck 63. Engaged in an airtight manner.

  The substantially planar permeation wall 65 is made in the form of a grid within the bottom surface of the insert 66.

  The front surface 69d of the application element 69a may not be in contact with the permeation wall 65, as shown.

  The front surface 69d can be retracted under the action of pressure in the container 61, which favors a good distribution of the product on the surface of the application element.

  To create a pressure in the interior space 68 containing the product, the user presses the cap 69b, thus causing the bellows-shaped portion 64 to fold over itself.

  The device 70 represented in FIG. 5 comprises a container 72 in which the receiving head of the applicator is mounted on its neck 74, the receiving head comprising an internal part 76 in which an application element 77 can be received. And an external bellows 75.

  To create pressure, the user presses the closure cap 78, thus causing compression of the bellows 75 and lowering of the interior portion 76 into the container 72.

  The use of inserts such as insert 66 is advantageous because different inserts can be easily mounted on the same type of container depending on the nature of the product to be dispensed and the nature of the application element.

  The insert can be realized in various ways, and the permeation wall can be constituted by, inter alia, a woven fabric, a perforated plastic film, a weld or a double-formed screen.

  As an example, in FIG. 6, the upper end is provided with an outwardly directed rim 82 to help secure it onto the container, and the lower end is an inwardly directed annular rim 83 to help secure a screen 84 secured onto its lower surface. An insert 80 having a rotating cylindrical side wall 81 of axis X is provided with

  In the example of FIG. 7, the insert 90 has an outwardly directed annular rim 92 at the upper end to help secure it on the neck of the container, and at the lower end has an open bottom surface 93 traversed by a plurality of openings 94. Included is a rotationally symmetric side wall 91 of axis X.

  The screen 95 is retrofitted on the bottom wall 93.

  The mesh of the screen 95 has a smaller cross section than the cross section of the opening 94 of the wall 93.

  The wall 93 serves as a mechanical support for the screen 95 and at the same time favors the accumulation of product in contact with or near this screen 95, thus creating a build-up of pressure in the interior space containing the product. At that point, the product present in opening 94 will be extruded through screen 95.

  The insert 100 shown in FIG. 8 is extended outwardly by an annular rim 102 at the upper end to help secure it onto the container and closed at the lower end by a bottom wall 103 containing an opening 104. Has a rotationally symmetric side wall 101.

  Elements, such as foam layer 106 with large open cells, may be inserted under bottom wall 103 in a manner that favors retention of the product in contact with lower surface 105 of bottom wall 103. It is retrofitted on top.

  In the example of FIG. 9, the insert 110 has a rotationally symmetric side wall 111 about the axis X with an upper portion annular rim 112 and an open bottom wall 113.

  A retaining mechanism 115 is secured to the insert, the retaining mechanism having a solid wall 116 located below the bottom wall 113 and spaced therewith in which the product is located. Can be held.

  The retaining mechanism 115 has a side wall 118 fixed on the side wall 111 of the insert with a side opening 119 allowing the product to reach the aforementioned spacing 117.

  The wall 116 has a substantially conical shape, so that the height of the gap 117 decreases as approaching the axis X.

  The holding mechanism also serves as a deflecting device to guide the circulation of air in the space 117.

  Of course, the invention is not limited to the embodiments described.
