Description

DEVICE FOR CONDITIONING AND DISPENSING A COSMETIC PRODUCT

The present invention relates to a device for packaging and dispensing a cosmetic product.

The invention more particularly relates to a device for dispensing a cosmetic product on a sampling surface for the application of the cosmetic product.

"Cosmetic product" means any product as defined in Regulation (EC) No 1223/2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products.

US20090196677A1, US878182 and WO0076873A1 are known, packaging and dispensing devices having a slot-shaped dispensing orifice for dispensing the product directly onto the selected surface in the form of a ribbon or a sheet of product. .

However, these devices do not allow to distribute the product on a sampling surface of said devices to be subsequently applied to the chosen surface.

Documents EP2422644A1, FR2856388A1 and EP0108636A2 are known, packaging and dispensing devices having a slot-shaped dispensing orifice situated on a convex dome making it possible to distribute the product in the form of a ribbon or a sheet of product. on the convex dome. The product is then applied to the chosen surface using the dome.

However, these devices do not allow to distribute the product cleanly on a sampling surface of said devices to be subsequently applied to the chosen surface, the convex shape does not allow easy removal of the product with the fingers.

Finally, documents FR2654078A1 and WO2005087618A1 are known, packaging and dispensing devices having a dispensing orifice located in the center of a surface of concave sample to distribute the product. The product is then removed with the fingers and then applied to the chosen surface.

However, these devices do not allow to distribute the product properly in the form of an aesthetic product tape on the sampling surface of said devices.

The present invention therefore aims to provide an improved set of packaging and dispensing of a cosmetic product in particular to overcome the aforementioned drawbacks.

For this purpose, the invention proposes a device for packaging and dispensing, in particular for cosmetic products comprising: a container adapted to contain a product, a sampling surface bound to the container extending along a median plane M, and a distribution duct opening through a product dispensing orifice for dispensing the product outside the container, the conduit extending along a Y distribution axis.

According to the invention, the distribution axis Y forms an angle α with at least one axis perpendicular to the sampling surface, the angle α being between 20 ° and 90 °, and in particular between 30 ° and 80 °.

In addition, according to the invention, the container advantageously contains a product with a viscosity of between 5 Pa.s and 20 Pa.s, in particular between 10 Pa.s and 13 Pa.s.

The invention advantageously allows to be able to distribute the product cleanly on the sampling surface without agglomerating at the orifice.

According to other features of the invention, the distance between the dispensing orifice and the sampling surface may be greater than or equal to 2 mm, in particular greater than or equal to 5 mm.

The height H between the median plane M of the sampling surface and the dispensing orifice may be greater than or equal to 2 mm.

The container may extend along a main axis X-X, the distribution axis Y being non-parallel to the main axis X-X.

The sampling surface can be concave. The dispensing orifice may be a slot whose length ratio over the width U 1 is greater than or equal to 2.

The slot whose length L can be between 3mm and 20mm, and whose width t is between 0.5mm and 3mm.

The container may comprise a flexible wall.

The device may comprise a dispensing member adapted to bring the product of the container to the dispensing orifice.

The distribution duct can open directly into the container, that is to say that no dispensing member is interposed between the container and the dispensing duct. Thus the product does not undergo or very little shear stress before passing into the distribution duct, which allows to maintain its physical properties for optimal distribution on the sampling surface. In addition, it makes it possible to dispense products of high viscosity, which can not pass through a pump or valve-type distribution member.

The distribution duct may have a length greater than or equal to 0.6 mm, more preferably greater than or equal to 0.8 mm, or even greater than or equal to 1.5 mm.

The container may contain a cosmetic product such as a skin care product, a skin makeup product, a hair product, or a sunscreen product.

The invention may be better understood on reading the following description of nonlimiting examples of implementation thereof, with reference to the appended drawings, in which:

FIG. 1 represents an example of a packaging and dispensing device according to a first embodiment of the invention;

- Figure 2 shows a sectional view along the X-X axis of the device of Figure 1;

- Figure 3 shows a sectional view along the axis XX of a variant of the device of Figure 1; FIG. 4 represents an example of a packaging and distribution device according to a second embodiment of the invention;

FIG. 5 represents a sectional view along the X-X axis of the device of FIG. 4; and

FIG. 6 represents an example of a sheet of product distributed by a device of the invention.

According to a first embodiment of the invention, with reference to FIGS. 1 to 3, a device 1 for packaging and dispensing a cosmetic product comprises a container 10 containing a cosmetic product P, a sampling surface 20 bound to the container 10, and means for dispensing the cosmetic product from the container 10 to the sampling surface 20.

The cosmetic product P advantageously has a semi-solid galenic substance for example having a texture of a cream, a gel or a paste. For this purpose the product P advantageously has a viscosity at room temperature of between 5 Pa.s and 20 Pa.s, better still between 10 Pa.s and 13 Pa.s.

Without limitation, the cosmetic product P contained in the container 10 may be a skin care product such as a moisturizing or anti-wrinkle cream, a serum or a cleaning gel, a sunscreen cream, a slimming cream, or a scrubbing product.

The cosmetic product P can also be a skin makeup product such as a foundation, or a hair product such as a fixing gel or a hair care mask.

The container 10 is a hollow body formed of a cylindrical peripheral wall January 1, closed at one end by a bottom 12, and open at the other end. The container described in this example is a rigid jar.

The opening 14 of the container 10 is defined by a neck 16 extending from a shoulder of the peripheral wall of the container 10. The axis of the opening 14 is a longitudinal axis XX which is also the axis according to which mainly extends the device. The outer wall of the neck 16 has a thread 18.

A closure element 40 of the opening 14 is screwed onto the container 10. For this purpose the closure element 40 has a first outer skirt 41 whose inner wall has a thread complementary to the thread 18 of the neck 16 of the container 10. The closing element 40 comprises a plate 42 extending from the first outer skirt 41 facing the opening 14.

The tray also has a second cylindrical skirt 43 extending from the tray 42 away from the container 10. This second cylindrical skirt 43 extends away from the edge of the tray 42 so that the closure member comprises an outer shoulder 44. The outer wall of the second cylindrical skirt 43 has a hooking means 45 located between the shoulder 44 and the upper edge of the second skirt 43. For example, this hooking means 45 is formed by an annular bead protruding radially from the outer wall of the second skirt 43. The attachment means 45 removably hold a protective cover (not shown) of the device 1. The releasable snap fastener is exemplified, and any other attachment means for releasably securing a cover may be suitable, such as a snug fit or thread. Alternatively the cover may be a capsule connected to the plate by a thin hinge.

The plate 42 has at its center a substantially cylindrical cavity 46 in which the body of a dispensing valve 50 is mounted.

A first end of the body of the valve comprises an actuating rod 51, emerging towards the outside of the container 10. The axis of the actuating rod 51 coincides with the axis XX of the container 10. The rod of Actuation 51 also forms a channel for dispensing the product P contained in the container 10.

The other end of the body of the valve 50 comprises a support passing through the center of the plate 42, and on which is mounted a dip tube 52 extending to the bottom 12 of the container 10. In this example the valve body forms a pump which forms the dispensing means of the product P. The construction details of the valve 50 are within the skill of those skilled in the art and therefore will not be described in detail here.

A distribution and sampling plate 60 extends mainly transversely to the X-X axis. The distribution and sampling plate 60 comprises a concave portion 21 defining the sampling surface 20, and a convex portion 22. This distribution and sampling plate 60 is therefore not symmetrical with respect to the X-X axis.

The peripheral edge of the distribution and sampling plate 60 comprises a cylindrical return 62 extending towards the container 10 so as to slide against the inner wall of the second cylindrical skirt 43.

A dispensing duct 25 opens through a dispensing orifice 23 preferably at the level of the convex portion 22. Preferably, the dispensing orifice 23 is not located in the center of the plate 60, but it is off-axis with respect to the axis principal XX of the device 1.

The distribution duct 25 has a length greater than or equal to 0.6 mm, more preferably greater than or equal to 0.8 mm, or even greater than or equal to 1.5 mm. This distribution duct 25 can be made by the thickness of the wall forming the plate 60. The distribution duct 25 can also be produced by a pipe extending from the wall forming the plate 60.

A sleeve 24 advantageously extends in the extension of the distribution duct 25 towards the container 10. The sleeve 24 can form a bend with the duct 25. This sleeve 24 is adapted to receive the end of the actuating rod 51 of the dispensing valve 50. The end of the actuating rod 51 is for example mounted tightly in the sleeve 24.

Such an arrangement makes it possible, when the user exerts pressure on the distribution and sampling plate 60, to move along said axis XX and said plate 60 and the actuating rod 51 in order to activate the valve and to distribute a portion of product P contained in the container 10 towards the sampling surface 20 via the conduit 25 and the dispensing orifice 23.

The orifice 23 may also comprise a closure element, not shown in the figures, in order to prevent impurities from entering the supply channel of the product P formed by the actuating rod 51.

The sampling surface 20 is a concave portion of the tray. Alternatively the sampling surface 20 could be flat. The sampling surface 20 extends mainly along a median plane M. The plane M is, for example, perpendicular to the X-X axis, as in the device represented in FIGS. 1 to 3.

The sampling surface 20 receives the product dispensed through the dispensing orifice 23. Said sampling surface 20 comprises in particular the first zone with which the product P comes into contact during dispensing. In addition, the sampling area is also defined by a second zone contiguous to the first zone and receiving more than 70% or more than 90% of the product dispensed.

By way of example, when the dispensing orifice is positioned on a convex portion and the sampling surface can be a continuous concave portion with the convex portion, the sampling surface can start from the inflection line between the two portions concave and convex.

According to the invention, the distribution axis Y of the distribution duct 25 forms an angle α with at least one axis perpendicular to the sampling surface 20, the angle α being between 20 ° and 90 °, even better understood between 30 ° and 80 °. Preferably, all the axes perpendicular to the sampling surface 20 form an angle α with the distribution axis Y, a being between 20 ° and 90 °, more preferably between 30 ° and 80 °.

In addition, the difference in height H, measured perpendicularly to the median plane M of the sampling surface, between the dispensing orifice 23 and the median plane M of the sampling surface 20 is greater than 2 mm, or even greater than 5 mm. When the sampling surface is concave, the difference in height, measured perpendicularly to the median plane M of the sampling surface 20, between the dispensing orifice 23 and the bottom of the concavity, is preferably greater than 2 mm.

Preferably, the dispensing orifice 23 is a slot of width t and of length L. The ratio of the length to the width (L / t) advantageously being greater than or equal to 2.

The length L is between 3 mm and 20 mm, more preferably between 5 mm and 10 mm.

The width t is between 0 mm and 3 mm, more preferably between 0.5 mm and 2 mm. A width equal to 0 mm is for example obtained when the slot is formed by two flexible lips in contact with each other and lifting away from under the pressure of passage of the dispensed product. Preferentially, the width t of the slot is non-zero.

The distance, measured along the wall of the plate, between the dispensing orifice 23 and the sampling surface is non-zero, and preferably greater than or equal to 2 mm, more preferably greater than or equal to 5 mm.

The slot preferably extends along a principal axis Z-Z substantially perpendicular to the axis X-X of the device 1 in order to deliver a ribbon of horizontal product.

The operation of this device is as follows.

The user wishing to take product P, poses the bottom of the container

10 on a flat surface then exerts pressure on the distribution plate 60 to dispense a portion of product P. The X-X axis is then substantially perpendicular to the planar surface and corresponds to the gravitational axis.

The pressure causes a displacement of the distribution plate 60 and the rod 51 of the pump for bringing a dose of product P from the container 10 to the dispensing orifice 23.

With a slot-shaped distribution orifice 23 having an angle α with the sampling surface 20, the product P is then dispensed in the form of a ribbon from the orifice 23 and falling towards the sampling surface 20 below. the dispensing orifice 23 under the action of the gravitational force. This product ribbon P is shown in FIG. The ribbon takes the form of a sheet of product advantageously having loops in the form of waves as shown in FIG.

The sampling can then be performed by the fingers of the user on the sampling surface 20, before application to the area of the body intended to receive the product.

In a variant shown in FIG. 3, the dispensing means is a piston 70 sliding in the container 10 in the direction of the dispensing orifice 23. The dispensing and sampling plate 60 is then fixedly mounted on the container 10. Said plate 60 may for example comprise a skirt snapped on the neck 16 of the container 10. The piston 70 is for example actuated via a threaded rod 72 connected to a manual actuating member 74 rotatably mounted about the longitudinal axis XX. In this example the bottom 12 is pivotally mounted relative to the side wall January 1 of the container 10. The rotation of the bottom 12 relative to this side wall 1 1 can induce a rotation of the threaded rod 72 and a translation of the piston 70 cooperating with the threaded rod 72 but fixedly mounted in rotation about the axis XX in the container 10. In this embodiment the distribution conduit 25 opens directly into the volume of the container 10 containing the product P, the displacement of the piston 70 forcing the product P to pass through the distribution duct towards the dispensing orifice 23.

A second embodiment of a device according to the invention is shown in FIGS. 4 and 5.

This device is substantially similar to the device of the first embodiment, described above. The references of the identical parts were incremented by one hundred compared to those of the first embodiment.

This device 101 for packaging a cosmetic product P comprises a container 1 10 containing a first cosmetic P, a sampling surface 120 bound to the container.

The container 1 10 of this second embodiment is a flexible wall container such as a tube or a bag. This container 1 10 therefore defines a cavity intended to contain the product P, the cavity being formed by a flexible outer wall January 1 for example tubular, one end of which is closed by a bottom January 12 for example made by clamping and welding the flexible wall January 1 January.

The open end of the container 1 10 comprises a neck 1 16 extending from a shoulder of the flexible outer wall of the container 1 10. The axis of the opening of the neck 1 16 is a longitudinal axis XX which is also the axis which mainly extends the device. The outer wall of the neck 1 16 comprises a fastening means 1 18 such as an annular screw thread or rim as in the example shown.

The distribution of the product P is then effected by a pressure on said flexible wall which allows to generate an overpressure in the container to expel the product contained in the container.

A dispensing head 180 is snapped onto the container 1 10. For this purpose, the dispensing head 180 comprises an outer skirt 181 whose inner wall comprises a groove complementary to the annular bead 1 18 of the neck 1 16 of the container 1 10. The external skirt 181 is complementary to the outer wall of the neck 1 16 of the container 1 10 to be fixed concentrically around said neck 1 16.

The dispensing head 180 also comprises an outer distribution and sampling wall 160 attached to the outer skirt 181.

The outer wall 160 of the dispensing head 180 comprises a sampling portion 121 extending mainly along a median plane M.

This sampling portion may be a concave portion defining the sampling surface 120.

The outer wall 160 of the dispensing head 180 comprises a portion comprising a distribution duct 125 opening through a dispensing orifice 123. This part closes the inner skirt for example by extending substantially perpendicularly or obliquely to the axis X-X. This wall comprising the dispensing orifice 123 may be convex.

The distribution duct 125 is made in the thickness of the outer wall 160 and in particular has a length greater than or equal to 0.6 mm, for example equal to 0.8 mm. The distribution conduit 125 opens directly into the container.

The dispensing orifice 123 may or may not be located in the axis of the main axis X-X of the device.

The distribution axis Y of the distribution duct 125 forms an angle α with at least one axis perpendicular to the sampling surface 120, the angle α being between 20 ° and 90 °, for example substantially equal to 80 °.

Preferably, all the axes perpendicular to the sampling surface

120 forms an angle α with the distribution axis Y, a being between 20 ° and 90 °, more preferably between 30 ° and 80 °.

Moreover, the difference in height H, measured perpendicular to the median plane M of the sampling surface, between the dispensing orifice 123 and the median plane M of the sampling surface 120 is greater than 2 mm, for example equal to 3 mm. .

As in the first embodiment, the dispensing orifice

123 is preferably a slit of width t and of length L. The ratio of the length to the width (L / t) advantageously being greater than or equal to 2.

The length L is for example equal to 5 mm. The width t is for example equal to 1 mm.

The distance, measured along the wall of the tray, between the dispensing orifice 123 and the sampling surface 120 is non-zero, that is to say that when the product is dispensed, it does not fall back to the level of the dispenser. dispensing orifice but further on the sampling surface.

The slot extends along a principal axis Z-Z substantially perpendicular to the axis X-X of the device 1 in order to deliver a ribbon of horizontal product.

The peripheral edge of the outer wall 160 advantageously extends from the outer skirt 181 to the shoulder of the container 1 10, in particular so as to come in the extension of the flexible wall 1 January 1 of the container 1 10. This peripheral edge may comprise means for receiving and attaching a protective cover (not shown). The dispensing head 180 also has an internal cylindrical skirt 182 extending around the orifice 123 from the outer wall towards the container 1 10. This inner skirt 182 concentrically extends into the outer skirt 181 so as to to fit snugly against the inner wall of the neck 1 16 of the container 1 10. The inner skirt 182 provides communication from the inside of the container to the dispensing orifice 123 of the wall of the dispensing head 180. Such an assembly allows, when the user exerts pressure on the flexible wall of the container 1 10, to dispense a portion of product P contained in the container 1 10 to the sampling surface 120 via the dispensing orifice 123, to avoid leakage of product through another passage at the neck of the container 1 10.

The operation of this device is as follows.

The user wishing to take product P, takes the container 1 10 and positions it substantially horizontally so that the sampling surface 120 is also horizontal. The X-X axis is then substantially perpendicular to the gravitational axis.

The user then exerts pressure on the flexible wall 1 January 1 of the container 1 10 to dispense a portion of product P.

The pressure generates an overpressure in the container 1 10 causing a displacement of the product P of the container 1 10 to the dispensing orifice 123.

With a slot-shaped orifice 123 and a distribution duct

125 having an angle α with the sampling surface 120, the product P is then distributed in the form of a ribbon from the orifice 123 and falling towards the sampling surface 120 located below the dispensing orifice 123 under the action of the gravitational force.

The sampling can then be performed by the fingers of the user on the sampling surface 120, before application to the area of the body intended to receive the product.

The invention is not limited to the illustrated examples. The characteristics of the various examples may especially be combined within non-illustrated variants. The expression "comprising a" shall be understood as meaning "containing at least one" unless the contrary is specified.
