The invention relates in particular to a dispensing port for packaging and dispensing viscous concentration products in the form of creams, pastes, ointments, balms or gels. The invention is particularly suitable for packaging and dispensing cosmetic, dermatological or medical products, such as skin creams. The present invention aims in particular to facilitate the distribution of the contents of such ports.

Pots have been steadily widely used in the field of makeup and skin care. The pot is particularly well suited for packaging such products that are easily accessible to the contained product, especially when the product is directly lifted by hand. Moreover, by the maximum opening, this receptacle can be emptied completely, which is particularly necessary for products that are expensive to sell to the consumer relative to the weight of the product.

One problem with this type of packaging and dispensing device concerns the protection of the contents, in particular the contact with ambient air which may adversely affect this kind of product. Another problem relates to "contamination" associated with this method of lifting a product using a finger. For the latter problem, a method of lifting the product by a spatula has been proposed. However, this lifting method does not protect the contents from contamination of the spatula with fingers or contact with air.

Another known method involves protecting the product by a disk covering the free surface of the product, which disk is arranged in a plane that is horizontal to the plane of the disk, that is, at least one opening substantially perpendicular to the axis of the port. Have In a general manner, the distribution of the product is done by pressing the disk into the port, which is a simple sliding action according to the example disclosed in document GB-A-1,050,984 or, in particular, according to the example disclosed in document DE-A-37 26 729. It is made through the thread formed on the inner surface and by applying a rotational action that can be engaged corresponding to the thread formed on the outer circumference of the disk. If the pressure exerted on the inside of the port is exceeded, the product flows out of the disc opening.

The disk must be moved very parallel to the port's axis of symmetry to prevent product leakage at the junction between the disk's periphery and the inner cylindrical wall of the port. As more product is lifted, the disc will gradually descend to the bottom of the pot. Products that lift the closure element from the bottom of the receptacle become increasingly difficult to use.

Thus, while the prior art provides a port in which the disk remains fixed high relative to the bottom of the port, the disk remains free to rotate in the groove of the port. In order to allow the product to be discharged, in the example disclosed in document DE-A-31 00 529, a disk is provided with a wall extending into the port to engage the panel fixed at the port, so as to move this wall relative to the fixed panel. It defines the chamber which changes the internal space accordingly. The product contained in this chamber can be compressed by the aggregation of the wall compared to the fixed panel. This movement of the wall is obtained by the rotation of the disk about an axis formed by the axis of symmetry rotation of the port.

The product is compressed so that the product is dispensed on the top surface of the disc and spills parallel to this axis of rotation. In particular, the product flows into the interior of the port in two orthogonal directions, the first direction of which the wall about the fixing panel is given in a plane perpendicular to the axis of rotation by this rotation, the second direction being the position of the exit hole of the disc Is given by Thus, the product flows out in a direction that can weaken its chemical structure.

A variant of the port according to document DE-31 00 529 is disclosed in document US-B-6,422,424, wherein the disc comprises two walls extending perpendicularly to the disc inside the port, each having a panel fixed separately within the port and Contact. Thus, the ports can be used to dispense two products that are each isolated in a chamber defined between one of the walls and one of the fixed panels. These two products each appear through two openings in the disc. These openings face in the radial direction, each of which is arranged in a part of the fan of the closing element which is most in communication with the chamber defined by this fan. This type of port cannot be packaged separately from the two products and therefore cannot be distributed simultaneously from one and the same hole.

As disclosed in document FR-852,719, rigid receptacles for dispensing paste products under pressure are also known in the art.

In the prior art, there is a need for ports of other configurations that are simple to manufacture and that are installed in a sanitary dispensing system that minimizes the components to minimize manufacturing costs. Moreover, other dispensing operations other than those required to adjust other ports of the prior art are also required. In addition, this new dispensing operation should not interfere with the physicochemical structure of the product, which in some cases may be unstable.

An object of the present invention is a device for packaging and dispensing cosmetics, in particular cosmetic and / or skin care products, comprising a container forming one or more recesses capable of containing a product, said recesses A first wall at least partially defining an inner surface of the second wall; and a second wall rotatable relative to the first wall about a rotation axis, wherein when the second wall rotates about the axis, the angle difference between the two walls is decreased. In the device being reduced,

The second wall has an outer circumferential edge, and when the second wall rotates about the axis, at least a portion of the outer circumferential edge is leaktightly coupled to the inner surface, and

To solve one or more of the problems described above with a device in which the second wall is provided with at least one outlet hole so that the product can be distributed in an outflow direction different from the direction of the axis of rotation in response to the reduced angle difference.

Preferably, the container is configured such that, when placed on the surface in a suitable manner, the adjustment of the second wall and the lifting of the product can be made with one hand.

Advantageously, the two walls each comprise two sides that can meet together at two arbitrary points, in order to optimize the space of the container when the angle difference is small.

Moreover, due to the fact that the product is contained in the recess, the product can preferably be accessed through the outlet hole, limiting the risk of contaminating the product. When the second wall is rotated with respect to the first wall, the product is compressed in the recess and flows out through this outlet hole to be dispensed from the device.

For example, the exit hole is defined through the second wall at regular intervals from the edge of this wall. In a variant, the exit hole may appear at the free end of the second wall.

In particular, considering the opening of the recess, the edge of the wall representing the recess has, for example, the edge of the first wall partially representing this opening, and the second wall can at least partially close this opening.

Advantageously, the inner surface can be defined at least in part by a continuous surface formed by a plurality of arcs each centering in parallel with one another along the axis of rotation. For example, these arcs can be identical to each other and can be superimposed on one another to define a space representing a portion of the cylinder as the first wall. In this case, the two walls of the recess can each be defined by a continuous surface formed by a plurality of continuous portions between one or more points of each such arc and the axis of rotation. In particular, one or more of the two walls may be defined by a continuous surface, each center formed by a number of radii along the axis of rotation. Thus, each connection between the point of the arc and the axis of rotation corresponds to a radius.

In particular, at least one of the two walls, preferably both walls, may be substantially flat.

In the first embodiment, the inner surface of the recess defines a portion or sphere of the sphere. In particular, the inner surface of the recess may be defined in quarter or hemispheres.

In a second embodiment, the inner surface of the recess defines a portion of the cylinder, preferably a quarter cylinder.

For example, one of the two walls can be fitted to the other of the two walls. For this purpose, for example, it may comprise means for fitting the two walls together. For example, the lugs represented by the second wall are engaged in corresponding slots provided in the container, and the axis of rotation of the hinge can pass through these lugs.

Optionally, the two walls can be made directly into a single body by molding, in which case the axis of rotation is formed in the film hinge which is defined by the contact between these two walls.

For example, the container is made by injection molding. In a variant, one of the walls consists of a second elastomeric structure by over-molding a first rigid structure, for example made of polyethylene or polypropylene, with the elastomeric structure appearing at the edge of this wall. With this structure, the manufacturing tolerances of the recesses are generated by the elastomeric portion, which maintains leak-tight contact and provides effective contact of the rotatable wall with respect to the inner surface.

In a preferred embodiment, the device comprises a holder which can be placed in a stable position on the surface. Preferably, the holder contacts the opening in which the outlet appears, and one of the walls is accessible from this opening. The container may for example be fixed on top of the holder. Optionally, the holder may take the form of a circumferential skirt surrounding the container, which skirt may be formed simultaneously with the container formed during molding of the unit's injection.

In particular, it is an object of the present invention to provide an assembly comprising two devices, as described above, each device comprising one container, wherein the containers of these two devices are each arranged on one side of the divider. In this case, preferably the two containers can each contact with separate flaps, each of which is rotatably mounted about its own axis of rotation, but joined by a divider. In particular, these two containers may be symmetrical to one another with respect to the plane passing through this partition. Advantageously, the divider comprises two opposing planes. In this case, when the two rotary flaps are mounted in contact with the container, respectively, these rotation axes are parallel to each other. The two vessels can be placed together, representing a hemisphere. In this case, the plane of each side of the divider preferably extends in the intersecting plane, and the angle difference between these two planes is 5 to 15 °, and each container has a space slightly smaller than 1/4 sphere.

The invention can be better understood with reference to the following description and attached drawings. It does not limit the scope of the invention, but is shown by way of example only.

1 shows an apparatus 1 according to the invention, which comprises a container 2 defining a recess 4 which can hold a product to be packaged. The inner surface 5 of the recess 4 is defined by at least one first wall 6, the second wall 3 of the apparatus 1 at least partially recessing the recess 4 in the container 2. To act as a closure. The second wall 3 partially defines the outer circumference of the device 1.

The inner surface 5 is a continuous surface formed by a plurality of circular arcs. Each arc has a center located on axis 7, also called the center axis. 1 to 3, the arcs forming the inner surface 5 have the same opening angle and the same radius. Furthermore, each arc is arranged such that the two ends of each of these arcs are aligned along two lines 8 and 9, respectively. In Fig. 1, lines 8 and 9 are identical and form two straight lines parallel to each other. In this first embodiment shown in Figs. 1 to 3, the opening angle of this arc is 90 degrees.

The first wall 6 is a continuous surface formed by a plurality of connecting portions between at least one point on each arc and the central axis 7. Each connecting part is defined in terms perpendicular to the central axis 7, so that this first wall 6 is also continuous.

1 and 2, these connections are straight, parallel to each other and have the same length. The first wall 6 is flat and defined in the plane passing through the central axis 7. In FIG. 1, this first wall 6 passes through one of the lines (in this embodiment line 9) passing through the end of the arc.

The second wall 3 can be pivoted on the first wall 6 and rotated about the central axis 7 (also referred to as the rotation axis 7). The angular difference 100 between these two walls 3 and 6 changes in accordance with the rotational movement of the second wall 3 with respect to the wall 6. For example, in FIGS. 1-3, the angle difference 100 may vary in a range between 90 ° and 0 °. As a variant, the second wall 3 may be suitable for covering the angular difference 100 with respect to the first wall 6 which is larger than the opening angle of the inner surface 5.

In the embodiment shown in FIGS. 1 to 15, the first wall 6 is integral with the inner surface 5 and forms part of the inner surface, the second wall 3 rotating about an axis 7. Is arranged to. The second wall 3 is leak-tightly engaged with the inner surface 5 of the recess when rotating about the axis 7. Thus, the second wall 3 has a straight edge 50 extending along the axis 7 and a second free outer edge 51 in which the second wall 3 is in leak-tight contact with the inner surface 5. It includes. The outer line of this second free edge 51 is suitably formed to interact with the inner surface 5.

The available inner space of the recess 4 is axial until it rotates by the maximum opening angle of the inner surface 5 and / or until the second wall 3 is in support contact with the first wall 6. It is defined by the rotation of the second wall 3 relative to (7).

As a variant (not shown), the first wall 6 can also be moved relative to the inner surface 5, and itself can be pivoted about the axis 7. Thus, the outer circumferential edge of this first wall 6 is also in contact with the inner surface 5 when it is rotated about the axis 7. Thus, the two walls 3 and 6 can be rotated about the axis 7.

The container 2 defines an opening 10. In FIG. 2, the opening 10 appears between the second straight line (in this case line 8) and the central axis 7 passing through the end of the arc. In this embodiment as shown in FIGS. 1 and 2, the inner surface 5 comprises two side portions 11 and 12 extending at right angles to the central axis 7, so that the recess 4 is thus creamed. It defines the cavity that can hold the product. These two side portions 11 and 12 define the same disk portion of a fan shape equal to or greater than the fan top of the arc portion of the inner surface 5. The cavity is thus limited to a quarter part of the cylinder, the height of which is defined along the central axis 7.

The opening 10 is partially closed by the second wall 3. The product is placed in a container 2 under this second wall 3. In fact, the second wall 3 cooperates with the recess 4 to define the space 16. The second wall 3 has an outlet hole 14 through which a product contained in the space 16 of the recess 4 can be dispensed. In fact, the space 16 changes with the movement of the second wall 3 with respect to the recess 4 around the axis 7, and the product is compressed and flows out of the device 1 through the outlet hole 14. do. The user presses directly on the outer surface of the second wall 3 at the point where the outlet 14 is shown.

 The outlet hole 14 is formed in the second wall 3. The outflow of the product takes place at right angles to the wall with the outlet hole 14. These walls 3 and 6 are rotatable about an axis 7, which is included in the thickness of this wall. The outlet hole 14 penetrates through the thickness of the second wall 3, so that the outflow of the product exiting through the outlet hole occurs in a direction different from the axis 7.

In this case, the outlet hole 14 is formed through the second wall 3 as shown in Figs. The outlet hole 14 is preferably formed in the second wall 3 in the vicinity of the hinge 13. Since this outlet hole 14 is present in the second wall 3, the second wall 3 does not completely close the opening 10.

As a variant, the outlet hole 14 is formed of at least a portion of the second wall 3 formed so as not to contact the inner surface 5 or one of the side portions 11 and 12 when the hole 14 is formed. It can be formed at the free outer circumferential edge 51.

As shown in FIG. 2, when the user presses the second wall 3 directly with one or more fingers, the second wall can be rotated about the hinge 13 formed in the axis 7, and the outer peripheral edge As the 51 passes through the inner surface 5 and the sides 11 and 12, the product collects in the recess 4 until the space 16 is insufficient relative to the amount of product remaining. Then, the excess amount of product is discharged through the exit hole 14, and the user can put it directly on the finger. The second wall 3 is accessible from the outer surface of the device 1, and pressure is applied to the outer surface of the second wall 3 in the same direction as the resulting movement of the second wall 2.

The second wall 3 of FIGS. 1 and 2 is of flat structure and thus can also effectively interact with the first wall 6, which is shown flat in FIGS. 1 and 2. In particular, in order to empty the container 2 as much as possible, the two walls 3 and 6 are only covered with each other until a very thin product film, which cannot be discharged from the outlet hole 14, is left between the two walls. Initially, the second wall 3 is configured to contact each arc at the height of the line 8 and then traverse the entire inner curvature of the arc in intimate contact, so that the connection maintains leakage protection. Can be guaranteed. This is why the second wall 3 is pivoted about an axis passing through the center of each of these arcs.

In a variant, such as the cross-sectional view schematically shown in FIG. 3, the second wall 3 need not be flat, in which case it is chosen to effectively interact with the second wall 6. Thus, the second wall 6 is also configured not to be flat and becomes a corresponding portion of the second wall 3. 11 shows the device according to the invention in which the two walls 3 and 6 are formed in waves, which can be superimposed and attached at the height of the hinge 13 forming the axis of rotation 7. In the embodiment shown in FIGS. 3 and 11, the inner surface 5 represents a structure which forms part of a cylinder, in which the inner surface 5 comprises side portions 11 and 12, these side portions being flat and It preferably has two edges that can be wavy.

Preferably, the structure of the second wall 3 is formed so that it can be attached to the first wall 6 at all points, ensuring an optimum yield. Here, the yield refers to the amount of product conveyed into this apparatus 1 relative to the total amount of product contained in the apparatus 1. Thus, there are no residual pockets between the two walls 3 and 6, and all the products contained in the space 16 can be discharged through the outlet hole 14.

To this end and in this case, the second wall 3 and the first wall 6 are both formed by a number of connections, each of which is defined in a plane perpendicular to the central axis 7, which is defined in the same plane. The connection forming one of the walls 3 and 6 can be superimposed as shown in FIG. 3. This connection may be curved.

4 to 7 and 9, 10, 12 and 13, the second wall 3 has a free edge 51 with no part perpendicular to the axis 7, the inner surface 5 being It does not contain any side portions such as side portions 11 and 12.

In FIG. 4, the inner surface 5 has a surface formed of quarter spheres. In this case, the second wall 3 and the first wall 6 are of the same shape, preferably flat and have a half-disc corresponding to a radius of a quarter sphere whose radius defines the inner surface 5. ) Respectively. The outlet hole 14 is shown in the second wall 3. For example, the two walls 3 and 6 and the inner surface 5 are formed in one piece and are obtained by injection molding a thermoplastic material such as polyethylene or polypropylene. Thus, the second wall 3 is shaped to align with the first wall 6, so that the linear coupling between these two walls 3 and 6 forms a line whose thickness is reduced along the central axis 7. , Forming a bend or hinge 13 which makes the second wall 3 rotatable.

5 and 6, the container 2 has a recess 4 formed as a hemisphere. In this case, the inner surface 5 is individually shaped in the form of a hemispherical cup, and the second wall 6 can be shaped into a disc shape together with the first wall 3, with half of the disc welded to the edge of the cup. Thus, the film hinge represents the edge of this half disk welded to the cup. The film hinges are formed along the diameter of these discs, forming two stackable half discs that form the walls 3 and 6, respectively. Thus, the second wall 3 can be rotated about this hinge and can be rotated inside the cup.

In particular, when the second wall is located in a cup formed by the inner surface 5, in order to support the second wall 6, the cup comprises two lugs opposing in the radial direction at the inner surface thereof. These two lugs are in the same plane as the edge of the cup. Preferably the film hinge is placed on these two lugs. In this case, the angle difference 100 can vary from at least 180 ° to 0 °, gradually decreasing the hemispherical space 16.

In the cross section shown in FIG. 6, due to the pressure exerted in the direction of the arrow 15, the second wall 3 is rotated about the film hinge 13 which is superimposed on the central axis 7. The compressed product in the recess 4 with the space 16 reduced is pushed through the outlet hole 14. The outer circumferential edge 51 sweeps the inner circumference of the inner surface 5.

In a particular embodiment, at least the second wall 3 is obtained by over-molding the first rigid structure 17, for example made of polyethylene or polypropylene, with the elastomeric material 18. Preferably this elastomeric material forms an outer circumferential edge 51 in contact with the inner surface 5. Thus, the action of scraping action occurs in an optimal way. As shown in FIG. 7, a second wall 3 is obtained which can be over-molded and mounted in one container according to FIGS. 4 to 6.

In particular, this second wall 3 (see FIG. 7) is a diametrically opposed two lugs 19 and 20 configured to engage with two corresponding slots represented by the inner surface 5 or the second wall 6. To form a hinge 13 on which the second wall 3 can be rotated. The position of each of the slots and lugs can be changed. In all cases, the two corresponding slots are arranged in the axis corresponding to the central axis 7 of the inner surface 5.

In FIG. 12, another embodiment of the device 1 according to the invention comprises a second wall 3, the outer circumferential edge 51 of this second wall having no part extending at right angles to the axis 7. Define irregular curves that do not have. In particular, the irregular curve of FIG. 12 comprises three protrusions 52, 53 and 54 which extend at right angles to the axis 7, respectively. In a complementary manner, the inner surface 5 takes the form of an irregular cup.

In the variant as shown in FIG. 13, the second wall 3 is a triangle, the outer circumferential edge 51 defines two sides of this triangle, and the third side extends along the axis of rotation 7. 50 is formed. In this embodiment, the discharge hole 14 is located at the vertex of the triangle away from the axis 7. The height 55 perpendicular to the axis 7 defines the radius of the corresponding arc while forming the inner surface 5.

8 and 14, another embodiment of a container 2 made in the manner of the invention is shown, and FIG. 8 shows a top view of the container of FIG. 14. In this variant, the inner surface 5 has the shape of a cylindrical portion, and the cylindrical portion has radial projections forming a ring portion having the same opening angle as the cylindrical portion. In particular, in the longitudinal sectional view, this protrusion has a triangular cross section 21 extending beyond the edge 22 of the cylindrical portion 23.

In all embodiments of the device according to the invention shown in FIGS. 1 to 6, the container 2 always has substantially the same thickness, whether defining the inner surface 5 or the first wall 6. . For this reason, the container 2 always has at least one curved outer wall. Thus, a device of this kind cannot be placed on a surface such as a shelf in an appropriate manner, with the outlet hole 14 facing upward to prevent leakage of the product by gravity.

In order to position the device according to the invention on the surface in a suitable manner, a container may be proposed in which the thickness of the wall varies in order to provide at least two flat intersecting surfaces outside the inner surface 5.

Optionally, there may be an option to mount the container 2 on the holder 24. For example, as shown in FIG. 9, the holder 24 has a cylindrical structure that includes a base 25 that can be placed in a stable manner. The holder 24 also includes an opening 26 through which the container 2 can be inserted into the holder 24. The opening 26 is parallel to the base 25. The opening extends at right angles to the longitudinal axis X of the holder 24. For example, the container 2 comprises an outer collar configured to engage a corresponding protrusion on the inner circumference of the holder 24 for holding in the holder 24.

In the embodiment shown in FIG. 9, the holder 24 comprises a cover 27 capable of closing the opening 26. For example, the cover is configured to be screwed with a screw 28 on the outer circumference of the neck which represents the opening 26.

In particular, as shown in FIGS. 9, 10 and 15, a first container 29 such as a container 2 and a second container 30 are formed on both sides of the partition 31, respectively. In this case, the two containers 29 and 30 each have flaps 32 and 33 respectively forming a second wall, such as the second wall 3, each flap being the same as the inner surface 5 of the inner surface 5 of one container. Interact The partition 31 extends perpendicular to the face of the opening and the opening 26, such as the opening 10 of these two containers. The two vessels may be symmetrical to one another with respect to the plane passing through the partition 31.

Preferably, the divider 31 comprises two planes 31a and 31b forming a first wall, such as the first wall 6 of each container. Each vessel 29 and 30 defines a chamber in this case substantially in the shape of a quarter sphere, for example forming part of a sphere (FIGS. 9 and 10). Thus, the flaps 32 and 33 are in the form of half discs and are connected by means of a film hinge 34 to the center strips 36 which are substantially equal in length and inner diameter to each of the two containers 29 and 30, respectively.

This center strip 36 interacts with the part 37 of the divider 31 to ensure the retention of these flaps in their respective containers, in particular the flaps having their respective hinges to withdraw the product from the container. When rotated about the center, this interaction can withstand the stresses applied. In this case, the two hinges are parallel to each other. The center strip 36 preferably comprises an elastomeric deformable lug, such as a lug 60 which can be snapped into a corresponding slot, such as the slot 61 provided in the portion 37.

In particular, to enhance snap-on attachment, the portion 37 comprises one or more pinions 62 which are joined via corresponding grooves 63 formed in the center strip 36.

Preferably, two products can be packaged in two containers 29 and 30. In particular, it may contain products that must be mixed with each other immediately before application to prevent deterioration of the product quality. Advantageously, if the two products are to be mixed with each other before application, exit holes 38 and 39, such as exit holes 14 in each flap 32 and 33, are preferably arranged near the center strip 36. . These outlet holes 38 and 39 are slightly offset relative to one another, for example, and are not substantially symmetrical with respect to the plane passing through the partition 31, thus avoiding unintended contamination of the two containers.

Optionally, as shown in FIG. 15, if the two products are to be used quite separately, such as using one product during the day and the other at night, the two holes are placed in the more central area of their respective flaps. This can prevent the risk of products spilling out close to each other.

In all cases, as shown in FIG. 10, the user can take the product only from one side by pressing only one of the two flaps. In fact, the two hinges 34 and 35 are separate from each other. In this example, the user has already taken the product under the flap 33 and has not yet taken the product from the container 29.

In FIG. 15, the two flaps 32 and 33 are in the form of a right triangle formed in the opening 26 which is itself a triangle, and the axis of rotation 7 is perpendicular to the base of the equilateral triangle formed by this opening 26. .

To fill this kind of packaging device, the container is filled before a second wall, such as the second wall 3, 32 or 33, is placed in the container, or the second wall is provided with an opening such as the opening 10 of the container. It is possible to fill the recesses 4 which already partially close. In the latter case, the product can be inserted directly through the outlet hole 14.

Throughout this specification, the expression "comprising one" has the same meaning as "comprising one or more" unless stated otherwise.

In the example, the opening angle of the inner surface 5 is on the order of 90 degrees or 180 degrees, but this opening angle can be strictly any value of less than 360 degrees, preferably 270 degrees or less.
