The present invention relates to devices for packaging and applying a substance, such as a cosmetic or a care product.
German patent application DE 31 00529 A1 describes a device for packaging and dispensing a cream. The device comprises two portions that may turn relative to each other, and a chamber containing the cream. The chamber may be formed inside the device, with turning of one of the parts relative to the other causing the volume of said chamber to decrease and the cream to be dispensed directly via an outlet orifice. The device does not have an applicator device.
U.S. Pat. No. 3,085,281 discloses a receptacle for nail varnish including a bladed stirrer that may be rotated by the user using a knurled wheel at the bottom of the receptacle.
European patent application EP 1 177 741-A1 describes a receptacle including a stirrer that may be driven in rotation by the stem of the applicator.
French patent FR 1 374 719 describes a similar receptacle.
U.S. Patent Application Publication No. 2002/0007839 describes a packaging and applicator device having a piston engaged on a screw that may be turned by the user. Pressure exerted on the substance may be due to the piston moving axially. The piston must be prevented from turning relative to the body of the receptacle to be capable of being driven by the screw.
Packaging and applicator devices for mascara are also known that comprise an applicator comprising a brush mounted at the end of a stem with the other end of the stem being secured to a closure capsule for the receptacle, the capsule also constituting a handle. The receptacle may be generally elongate in shape and relatively narrow, so that the brush may extract most of the substance that may be contained in the receptacle. With such a device, a certain quantity of substance may be nevertheless never extracted by the brush and becomes lost after a chimney has been formed in the substance.
There exists a need, for example: to modify the appearance of devices for packaging and applying a substance and including an applicator; to make such devices easy to carry about in a handbag; to create a new technique for loading the applicator with substance on each use; where appropriate, to make more uniform the substance contained in the device for extracting the applicator or for feeding to the applicator, which may be advantageous, for example, for substances comprising a plurality of immiscible phases, such as two or even three or more different phases; to modify the texture of the substance and/or the rheology of the substance, where appropriate, for example, for thixotropic substances; to facilitate loading of the applicator with a predefined quantity of substance on each use; to ensure that the substance may be of the same quality on each use; to enable the quantity of substance that may be loaded onto the applicator to be controlled, where appropriate; to enable at least one characteristic of the substance, such as, for example, color, covering power, brightness, staying power, and/or rheology, to be modified by adding one or more additional compounds in quantities selected by the user; to enable the substance to be heated, where appropriate, by being placed in a microwave oven, and consequently to make the temperature of the substance uniform in the event of a temperature gradient arising inside the receptacle; to increase the extractable fraction, for example, so as to reach an extractable fraction greater than or equal to 90%, or even 95%, or more; and to enable a mirror to be mounted thereon, where appropriate.
The invention seeks to satisfy at least one, or even all, of the above requirements.
Exemplary embodiments of the invention provide a device for packaging and applying a substance, the device comprising: a receptacle for containing the substance, the receptacle comprising: a first part and a second part, the second part being turnable by a user relative to the first part; and an applicator.
In exemplary embodiments, the applicator may be loaded with substance by turning the first and second parts relative to each other.
In exemplary embodiments, the second part may define at least one surface in contact with the substance inside the receptacle. The applicator and the surface may be arranged in such a manner that turning the surface causes pressure to be exerted on the substance, for example, by the surface, thereby causing the substance to move toward the applicator. Such movement of the substance may occur in various exemplary embodiments around and/or through the applicator, in one direction only or in several directions, for example, in two opposite directions in alternation. The surface may preferably be configured in such a manner that substantially all of the substance contained in the receptacle may be used. Advantageously, the substance may thus be caused to move toward the applicator until the receptacle has been emptied substantially completely.
In exemplary non-limiting embodiments, the device may include an anti-rotation system that allows the first part to turn relative to the second part in one direction only. Such an anti-rotation system may comprise, for example, at least one elastically-deformable tab carrying a pawl that moves in contact with a ratchet.
For example, the tab may be made with one of the first and second parts and the ratchet may be made one with the other one of the first and second parts.
In exemplary embodiments, the applicator may optionally be removable. In exemplary embodiments in which the applicator may be removable, the applicator may be secured to the receptacle when not in use, and may contribute to closing the receptacle.
In exemplary embodiments, the substance may be suitable for being made uniform, where appropriate, inside the receptacle by mixing caused by turning at least one surface in contact with the substance inside the receptacle, for example, defined by the second part.
In exemplary embodiments, the device may advantageously be used for packaging a substance of creamy, pasty, or gelled consistency, such as mascara, for example.
Exemplary embodiments of the invention enable the substance to be dispensed onto the applicator even when the device may be of a shape that may be wide rather than long. Exemplary embodiments of the invention thus make it possible to change the appearance of devices used for packaging and applying mascara, for example. For example exemplary embodiments of the invention may enable the overall bulk of the device to be reduced, thus facilitating transport.
In exemplary embodiments, a ratio of a height of the receptacle over a greatest transverse dimension of the receptacle may lie in a range of about 0.1 to about 10, for example, being close to 1, for example.
In exemplary embodiments, the substance may be contained in an inside space of the receptacle and a ratio of a height of the inside space over the greatest transverse dimension of the receptacle may lie in a range of about 0.1 to about 10, for example.
Exemplary embodiments of the invention enable a mirror to be secured to the device. This may be not true of conventional devices for packaging and applying mascara.
For example, the first and second parts may co-operate by snap-fastening so as to enable the first and second parts to turn relative to each other while preventing any relative displacement in an axial direction.
In exemplary embodiments, the first and second parts may be assembled together to form a junction that may be leaktight. To this end, one of the first and second parts may include a sealing gasket or a sealing lip that co-operates with the other one of the first and second parts, for example.
In exemplary embodiments, the first part may define an inside space containing the substance. In other exemplary embodiments, the first and second parts may together define the inside space containing the substance. The first and second parts may, for example, define a size of the inside space.
In exemplary embodiments, the applicator may be situated in a center of the receptacle. In such embodiments, at least one surface in contact with the substance inside the receptacle, for example, defined by the second part, may be configured in such a manner that turning the surface moves the substance toward the center of the receptacle. For example, the surface may turn about the applicator when the applicator may be arranged for being refilled with substance by being inserted into the receptacle.
In exemplary embodiments, the surface that moves the substance toward the center of the receptacle on being turned need not be planar, and may be oriented in such a manner as to encourage flow toward the center of the receptacle.
Where appropriate, the surface may also be inclined upward or downward in such a manner as to produce also a flow of substance toward a top or a bottom of the receptacle.
In exemplary embodiments, the second part may co-operate with the first part to define at least two chambers inside the receptacle, with turning of the second part relative to the first part causing a volume of one of the chambers to vary in one direction and a volume of the other chamber to vary in an opposite direction. In such embodiments, the applicator may be dispensed substantially on a path of the substance flowing from one of the chambers toward the other one of the chambers.
In exemplary embodiments, the first and second parts may also define a chamber of variable volume. In such embodiments, turning the second part may cause the volume of the chamber to decrease, and may cause the substance to be dispensed toward the applicator.
In exemplary embodiments, the substance may be dispensed, for example, in a direction parallel to an axis of rotation of the second part. The substance may be dispensed toward the applicator, for example, when the applicator may be not housed inside the receptacle.
In other exemplary embodiments, the substance may be dispensed in some other direction, for example, a direction that may be not parallel to the axis of rotation, for example, in a direction that may be perpendicular to the axis of rotation.
In exemplary embodiments, the first part may include a bottom wall having a first portion in relief and a second portion in relief that co-operates with the first portion in relief so as to guide pivoting of the second part relative to the first part. The first portion in relief may comprise, for example, an indentation and the second portion in relief may comprise a stud engaged in the indentation, or vice versa.
In exemplary embodiments, the second part may include a blade. As used herein, the term “blade” should be understood broadly. The blade may be made integrally, i.e., monolithically, with the second part. In other exemplary embodiments, the blade may comprise at least one piece that may be fitted to the second part. The at least one piece may be made of a material that may be different from a material used for making a remainder of the second part, for example, a material that may be more rigid or more flexible, depending on a desired result. In embodiments in which the blade may be a separate fitting, the blade may be secured to a remainder of the second part by snap-fastening, for example.
In exemplary embodiments, the blade may be pierced by at least one opening, for example, a plurality of openings. This may reduce a force needed to cause the second part to turn relative to the first part, and, where appropriate, may reduce a force needed to mix the substance.
In exemplary embodiments, the second part may include an outer skirt that may be turned by a user.
In exemplary embodiments, the second part may also include a neck which may be threaded on an outside thereof so as to enable an internally-threaded closure cap to be secured thereto. Other means for fastening a closure cap on the neck may be used.
In exemplary embodiments, at least one surface in contact with the substance inside the receptacle, for example, defined by the second part, may extend to a wall of the first part that radially defines an outside of the inside space containing the substance. For example, this may enable a radially-outer edge of the second part to scrape substance off the wall, which may improve emptying of the receptacle. The surface may extend at least in part parallel to an axis of rotation of the second part. The surface may also extend at least in part in a radial plane containing the axis of rotation of the second part. The surface may extend about at least two radii, and the surface may be continuous. The surface may optionally intersect the axis of rotation. For example, the surface may be skew to a certain extent. For example, the surface may have a shape that may be adapted to improving a flow of substance over an entire height of the applicator. The surface may be configured specifically to cause the substance to rise, which would otherwise tend to accumulate at a bottom of the receptacle. The surface may thus be arranged to lift the substance as the surface turns, and may include a portion that slopes downward and in a travel direction of the surface.
The surface may also include a bottom edge that matches substantially a shape of a bottom wall of the receptacle, for example, so as to scrape off substance that has become deposited on the bottom wall. The surface may have a radially-inner edge that may be curved downward and inward, for example, so as to match substantially a shape of an applicator housed in the inside space. The surface may include a radially-outer edge substantially matching a shape of a side wall of the receptacle. The surface may include a radially-inner edge that substantially matches a profile of the applicator.
In exemplary embodiments, the device may include a handle member with a longitudinal axis substantially perpendicular to an axis of rotation of the second part. Where appropriate, the longitudinal axis of the handle member may coincide with that of the applicator.
In exemplary embodiments, the first part may define a backing surface and the surface defined by the second part may face the backing surface, at least in part, at an end of a turning stroke of the second part.
The backing surface may extend substantially radially toward a center of the receptacle. For example, the backing surface may be defined by a partition that projects into the inside space of the receptacle containing the substance.
In exemplary embodiments, the first part may include an outer covering.
In exemplary embodiments, the second part may be made as a single piece of plastics material. In other exemplary embodiments, the second part may comprise a plurality of component elements that are made separately and subsequently assembled together. For example, the second part may comprise an outer portion and an inner portion secured to the outer portion. The inner portion may be capable of turning relative to the first part without moving axially. For example, the inner portion may have an annular sealing lip that presses against the first part.
In exemplary embodiments, the first and second parts may be made out of different materials. This may reduce friction between the two parts and may facilitate turning one part relative to the other.
In exemplary embodiments, the device may include a dip tube.
In exemplary embodiments, the blade and/or the backing surface may extend at least in part along an axis that may be inclined relative to the axis of rotation so as to urge the substance toward the top or the bottom of the receptacle. Under such circumstances, the substance may be conveyed via a chimney toward the top, or may be held level with an inlet orifice of a dip tube in communication with a dispenser means.
In exemplary embodiments, the device may include a wiper member for wiping the applicator.
The wiper member may be molded together with the first and/or the second part, or may be fitted to one of the first and second parts, for example, fitted to the second part.
In embodiments in which the second part comprises an outer portion and an inner portion, one of the outer portion and the inner portion may carry the wiper member of the applicator. The wiper member may be made integrally, i.e., monolithically, with the inner portion, for example.
The wiper member may be made out of a material that may be different from that of the first and second parts and may be fitted to one of the first and second parts, or one of the first and second parts may be overmolded thereon.
The wiper member may be made of an injection-molded plastics material or out of a foam. Where appropriate or desired, the wiper member may be flocked. One of the first and second parts may include a perforated central chimney. The applicator may be received in the chimney.
For example, the applicator may be secured to a closure cap.
For example, the applicator may extend inside the receptacle when the closure cap may be in place thereon.
In exemplary embodiments, the applicator may include a stem that extends substantially parallel to the axis of rotation of the second part. In other exemplary embodiments, the applicator may include a stem that extends substantially perpendicularly to the axis of rotation of the second part, or with some other orientation. The stem may also be curved.
Where appropriate, the stem may include a narrow portion that comes into position in registration with the wiper member when in a storage position, thereby avoiding stressing the wiper member.
In exemplary embodiments, the applicator may be housed inside the receptacle in a space having the surface extending therearound.
In exemplary embodiments, the applicator may comprise a brush, for example, configured to apply substance to keratinous fibers, for example, the eyelashes and/or the eyebrows.
In exemplary embodiments, the applicator need not be a brush. For example, the applicator may comprise an endpiece made of elastomer or some other material, such as a felt or a foam, and may optionally be flocked. The applicator may include one or more cavities for filling with substance. The applicator may also comprise a ball, like a roll-on applicator, for example. The applicator may include a grid that may be flocked, at least in part.
In embodiments in which the applicator comprises a stem and an applicator element, the applicator element may have in cross-section a maximum dimension that may be, for example, less than, equal to, or greater than the diameter of the stem, depending on the nature of the applicator element.
In exemplary embodiments, the applicator does not extend into an inside space of the receptacle filled with substance. The device may include, for example, a permeable wall between the applicator and an inside space of the receptacle containing the substance.
In exemplary embodiments, the applicator may be secured to the second part at least when in use. The second part may include an internal duct arranged to feed substance to the applicator.
In exemplary embodiments, the device may include a closure cap. In such embodiments, the device may include a system that locks rotation of the closure cap relative to one of the first and second parts.
For example, the substance may be selected from: mascara, eye shadow, lipstick, eyeliner, a self-tanning substance, a care product, such as a lip care product, an anti-acne product, a spot concealer, a concealer of rings under the eyes, an after-sun product, a hair-care product, a dermatological product, a foundation, a deodorant and a care product for application around the eyes, this list not being limiting.
In exemplary embodiments, the substance may be solid or semi-solid at ambient temperature (20° C.).
For example, the substance may contain at least two phases that are immiscible, and may be made uniform by turning the first part relative to the second part.
In exemplary embodiments, the second part may include at least two blades.
In exemplary embodiments, the applicator may be off-center relative to the axis of rotation of the second part relative to the first. For example, the applicator may be swept through the substance when one of the parts turns relative to the other about the axis.
Independently or in combination with the above, exemplary embodiments of the invention may provide a device for packaging and applying a substance. The device may comprise: a receptacle for containing the substance, the receptacle comprising: a first part and a second part, the second part being turnable by a user relative to the first part; and an applicator suitable for placing inside the receptacle to be loaded with substance; the first part co-operating with the second part to define two chambers inside the receptacle, turning the second part relative to the first part causing a volume of one of the two chambers to vary in one direction and a volume of the other one of the two chambers to vary in an opposite direction, and vice versa, the applicator being placed on a path of the substance flowing from one of the two chambers toward the other one of the two chambers.
In exemplary embodiments, the extent to which the applicator may be loaded may be controlled, where necessary or desired, by acting on the amplitude or degree with which one of the parts may be turned relative to the other part.
Exemplary embodiments of the invention may also provide a device for packaging and applying a substance for application to at least one of skin, mucous membranes, nails and hair. The device may comprise: a receptacle for packaging the substance, the receptacle comprising a first part and a second part capable of turning relative to the first part about an axis of rotation; and an applicator suitable for being releasably secured to one of the first and second parts, in a manner that may be off-center relative to the axis of rotation, the applicator including an applicator element placed inside the receptacle in such a manner as to move in contact with the substance in the receptacle when the first and second parts turn relative to each other.
Exemplary embodiments of the invention may also provide a method of loading the applicator of a device as defined above with substance, in which the second part may be caused to turn relative to the first part through an angle that may be predefined as a function of the quantity of substance that it may be desired to deposit on the applicator.
Exemplary embodiments of the invention may also provide a kit comprising: a receptacle for containing the substance, the receptacle comprising: a first part and a second part, the second part being turnable by a user relative to the first part; an applicator, the second part defining at least one surface in contact with the substance inside the receptacle, the applicator and the surface being arranged in such a manner that turning the surface exerts pressure on the substance, causing the substance to move toward the applicator; and at least one additional compound for adding to the substance contained in the device.
For example, the additional compound may be one of a solvent, a coloring agent, a gloss agent, and a lubricating agent, for example, an oil.
Exemplary embodiments of the invention may also provide a method of making up in which the user inserts a desired quantity of at least one additional compound into the device as a function of the desired results, then makes the substance uniform by turning the first part relative to the second part.

The device 1 may comprise a receptacle including a first part 10 and a second part 20 capable of turning relative to the first about an axis of rotation X, coinciding with the longitudinal axis of the device 1 in the exemplary embodiment of
The device 1 may further comprise an applicator 2, which itself may include an applicator element 3, comprising a brush in the example shown.
The applicator element 3 may be connected by a stem 4 to a handle member 5, which also may constitutes a closure cap for the receptacle.
In the exemplary embodiment of
The stem 4 may be made, for example, at least in part out of a plastics material, and may comprise at least one material such as: polyamide (PA); polyethylene (PE); polypropylene (PP); polystyrene (PS); acrylonitrile-butadiene-sytrene copolymer (ABS); sytrene acrylonitrile copolymer (SAN); polyacetyl (POM) or polyethylene terephthalate (PET); this list not being limiting.
In the exemplary embodiment of
For example, the covering 12 may be retained on the pot 11 by friction, adhesive, heat-sealing, or snap-fastening. The covering may be made out of a metal, for example, while the pot 11 may be made out of a thermoplastic material.
The covering 12 may, where appropriate or desired, be made out of an elastomer material, for example, a thermoplastic elastomer, and may include projections on a surface thereof to make it easier for a user to hold.
In the exemplary embodiment of
As shown in
The pot 11, which may be made out of at least one plastics material, such as PE, PP, PA, POM, PS, ABS, SAN, or PET, this list not being limiting, may include a partition 16 that extends radially toward a center of the inside space 15 to a vicinity of the applicator element 3, and that may be substantially complementary in shape thereto.
The second part 20 may include an outside skirt 21 arranged to snap-fasten on the portion 13 in relief and made integrally, i.e., monolithically, in the exemplary embodiment of
The portion 13 in relief may be made, for example, in the form of a continuous or discontinuous annular bead so as to hold the first part 10 axially relative to the second part, while allowing the first and second parts to turn relative to each other.
The second part 20 may include a blade 23 made integrally, i.e., monolithically, with the skirt 21 and the neck 22, in the exemplary embodiment of
The blade 23 may preferably have a shape that matches a shape of both the applicator element 3 and the pot 11, respectively.
In the exemplary embodiment of
A radially inner edge 23b of the blade 23 may include a downwardly and inwardly curved bottom portion that substantially matches the shape of the applicator element 3.
The bottom edge 23c of the blade 23 may substantially match the shape of the bottom wall 44 of the receptacle, for example, so as to scrape the substance that may be present thereon.
The second part 20 may be made out of at least one plastics material, for example, PE, PP, PA, POM, PS, ABS, SAN, or PET, this list not being limiting.
It may be advantageous to use different materials for making the first and second parts, for example, to reduce friction between them.
When the second part 20 may be in place on the first part 10, as shown in
As shown in
The wiper member 30 may be of any type, and, for example, may have a flexible lip 31 defining a circular orifice 32 at a bottom end thereof, a diameter of the orifice being substantially equal to a diameter of the stem 4. In other embodiments, the orifice 32 may have some other diameter and/or may be of a shape that may be not circular.
The wiper member 30 may be made of a plastics material, for example, PE, PP, POM, PET, nitrile, silicone, ethylene polypropylene diene (EPDM), sytrene-isoprene-sytrene (SMAY BE), or sytrene ethylene polypropylene butadiene-sytrene (SEBS), a thermoplastic polyester elastomer, such as that known under the trademark Hytrel®, for example, a thermoplastic elastomer, such as that known under the trade name Santoprene®, for example, this list not being limiting.
The wiper member 30 need not be fitted in the neck, but may be molded therewith, or the neck may be overmolded thereon.
As shown in FIGS. 4 to 6, the blade 23 and the partition 16 together may define two chambers 15a and 15b inside the space 15. The chambers 15a and 15b may communicate with each other via a central region 15c in which the applicator element 3 may be situated when the applicator 3 may be in place on the receptacle.
Each main face of the blade 23 may define a rotary surface 40, one of which may exert thrust on the substance, depending on the direction in which the second part 20 may be turned.
The partition 16 may define backing surfaces 46. At an end of turning of the second part 20 relative to the first part 10, one of the rotary surfaces 40 may come substantially to overlie one of the backing surfaces 46.
When the user turns the second part 20 relative to the first part 10 in either direction, movement of the blade 23 inside the space 15 may cause a volume of one of the chambers 15a or 15b to decrease while causing a volume of the other of the chambers to increase, thereby causing the substance to flow from one chamber toward the other chamber through the central region 15c, thus enabling the applicator element 3 to be filled with substance.
In the exemplary embodiment of
When the second part 20 may be turned relative to the first part 10, for example, with the user holding the covering 12 in one hand and turning the outer skirt 21 with the other hand, movement of the blade 23 in the inside space 15 may cause the substance P to be stirred to some extent, which may contribute to making the substance P uniform.
In the exemplary embodiment of
The ratio hi/d of the height hi of the inside space 15 of the receptacle over the greatest transverse dimension d of the receptacle may lie in a range of about 0.1 to about 10, for example. For example, it may be possible for d>hi.
The stem 4 of the applicator may be made with a narrow portion 4a as shown in
In the exemplary embodiment of
In the exemplary embodiment shown in
The stem 4 of the applicator may be telescopic, for example, as shown in
The stem 4 may comprise a first portion, for example, a bottom portion 4b, engaged inside a second portion, for example, a top portion 4c, and capable of sliding inside the second portion parallel to the longitudinal axis Y of the applicator. The bottom portion 4b may be made with one end in relief that enables a travel stroke thereof in the other portion 4b to be limited.
When the applicator 2 may be in place in the receptacle, the stem 4 may be in a retracted position, for example, as shown in
When the user seeks to extract the applicator element 3 from the receptacle, the applicator element 3 may bear against the wiper member 30, thus enabling the stem 4 to be deployed and bringing the stem into the configuration shown in
Once the stem 4 may be deployed, the user may cause the applicator element 3 to pass through the wiper member 30.
On returning the applicator element 3 into the receptacle, the stem 4 may begin by retracting, after which the applicator element 3 may pass through the wiper member 30.
The use of a telescopic stem may be associated with receptacles other than that shown in
Where appropriate or desired, as shown in FIGS. 14 to 16, openings 45 may be formed in the blade 23 so as to allow the substance to pass through the blade 23 while the blade 23 may be moving.
The blade 23 may have multiple openings 45, for example, circular openings, as shown in
The through section made available to the substance by the opening(s) 45 may preferably be small enough to ensure that the required quantity of substance nevertheless flows through the central region 15c when the blade 23 may be moved.
Where appropriate or desired, the blade 23 may be skew, for example, including a bottom portion that may be curved downward and forward relative to the direction the blade moves through the substance.
The blade 23 may include a portion 23e that may be curved about an axis W perpendicular to the turning axis X, as shown in
Instead of curving the blade, it may be also possible to make the blade thicker in a bottom portion thereof so that the surface 40 that presses again the substance tends to lift the substance.
A skew blade may be made without openings 45.
The present invention may be not limited to a particular applicator element 3. For example,
As shown in
The bottom portion of the partition 16 may likewise have an L-shape extending toward the inside substantially as far as the axis X.
The first and second parts may be organized in multiple other ways without that going beyond the ambit of the present invention.
For example,
In the exemplary embodiment of
In the exemplary embodiment of
Where appropriate or desired, at least one of the first and second parts may be made with a chimney in which the applicator element 3 may be positioned when the applicator 2 may be in place on the receptacle.
In
The bottom wall 44 of the pot 11 may be made, where appropriate or desired, with a first portion 63 in relief, such as a stud, arranged to co-operate with a second portion 65 in relief, such as an indentation, formed in the bottom wall of the chimney 60.
In the exemplary embodiment of
The applicator element 3 may be received in the chimney 70 while the applicator 2 may be in place on the receptacle.
The second part 20 may be made as a single piece, by molding a plastics material, or in exemplary embodiments by assembling together at least two pieces that are made separately and then assembled together.
In the exemplary embodiment of
The outer portion 75 may be assembled to the inner portion 76 in various ways. The outer portion 75 may, for example, include the neck 22, and the inner portion 76 may include an insert 78 that may be engaged in the neck 22, the insert 78 being made, for example, integrally, i.e., monolithically, with a wiper member 79. The inner portion 76 may also include, for example, a plate 80 supporting the blade 23 and provided at its periphery with an annular sealing lip 82 that bears against the radially inside surface of the pot 11.
In the exemplary embodiment of
In the exemplary embodiments described above, the first part 10 may include a partition 16 defining at least one backing surface 46. It would not go beyond the ambit of the present invention for the first part 10 to include no such partition, as shown in
In the exemplary embodiment of
In
In the exemplary embodiments described above, the applicator may be extracted from the receptacle in a direction that may be substantially parallel to the axis of rotation X.
It would not go beyond the ambit of the present invention for the applicator to be extracted in a direction that may not be parallel to the axis X, and for example, in a direction Y that may be perpendicular to the axis X, as applies to the exemplary embodiment shown in FIGS. 26 to 28.
In this exemplary embodiment, the device 1 may comprise a first part 10 made with a neck 22 extending substantially perpendicularly to the axis X from the side of the first part 10. The pot 11 of the first part 10 may be closed by the second part 20. For example, the partition 16 may be made integrally, i.e., monolithically, with the pot 11 by molding material. The second part 20 may carry a mirror 90 on an outside face and a blade 23 which extends substantially parallel to the axis of rotation X.
The closure cap 5 may have an elongate shape so as to form a handle for the device 1 when the user seeks to make use of the mirror 90. This example shows that it may be possible for the applicator element to be constituted by an element other than a brush, and specifically by an endpiece having a tapering tip, for example.
In
In the exemplary embodiments described above with reference to the drawings, the applicator 2 may comprise an applicator element 3 that is to be extracted from the device during utilization, and that may be mounted at the end of the stem 4. In such embodiments, the applicator element 3 may be housed inside the receptacle containing the substance whenever the closure cap 5 is in place on the receptacle.
It would not go beyond the ambit of the present invention for the applicator element 3 to be permanently secured on the device and/or not to be housed while not in use entirely in the space containing the substance.
For example,
The device 100 may further comprise an applicator 102, which in this exemplary embodiment may comprise an applicator element 103, for example, comprising a foam, said applicator element 103 being carried by an inner skirt 150 of a closure cap 105 that may also act as a handle.
The cap 105 may include an annular sealing lip 151 pressing against the inside wall of a neck 122, which neck may carry an outside thread, for example, and may be made integrally, i.e., monolithically, with the second part 120.
In the exemplary embodiment described, the first part 110 may comprise a pot 111 defining an inside space 115, as shown in
The pot 111 may include a partition 116 extending radially toward the center of the inside space 115 to come close to the axis X, and near the top may include an annular sealing lip 114 provided on the outside with a portion 113 in relief serving to hold the second part 120. For example, the portion 113 in relief may be an annular bead.
The second part 120 may comprise an outer skirt 121 arranged to snap-fasten on the portion 113 in relief, and made integrally, i.e., monolithically, with the neck 122 in exemplary embodiments.
A blade 123 may also be made integrally, i.e., monolithically, with the outer skirt 121 and the neck 122 in exemplary embodiments.
The radially inner edge 123b of the blade 123 may be situated in a central region 115c of the inside space 115, preferably at a short distance from the radially inner edge of the partition 116.
In exemplary embodiments, the bottom wall 144 of the pot 111 may include a first portion in relief, for example, constituted by an indentation 124, that may be arranged to co-operate with a second portion in relief, for example, constituted by a stud 125, formed on the bottom edge 123c of the blade 123, so as to guide the blade 123 when turning.
The radially outer edge 123a of the blade 123 may extend nearly as far as the inside wall 142 of the pot 111, for example, so as to scrape off the substance that becomes deposited on said wall 142.
The device of
The blade 123 may define two opposite rotary surfaces 140 and the partition 116 may define two associated backing surfaces 146.
The partition 116 may co-operate with the blade 123 to define two chambers 115a and 115b. When the second part 120 is turned relative to the first part 110, the blade 123 moves, and its movement may be accompanied by the volume of one of the chambers 115a or 115b decreasing and the substance leaving that volume to go toward the applicator element 103.
In the exemplary embodiment of
In the exemplary embodiment shown, the applicator element 103 may comprise a foam, for example, including a recess 190 defining an inside surface 191 arranged to receive the substance P when the second part 120 is turned.
The closure cap 10S may have an annular sealing lip 151 co-operating with a wall 192 of the second part 120 that may extend around the applicator element 103.
In the exemplary embodiment of
This bottom wall may be extended downward at a periphery thereof by a skirt 150 defining a housing 151, for example, suitable for housing a mirror or a sample of substance. In the exemplary embodiment shown, the bottom wall 144 has a bulge in the housing 151 that enables the indentation 124 to be formed.
In the same manner as that described with reference to
The substance P may be expelled toward the applicator element when the blade 123 is turned in either direction by the user. A duct 193 may be formed integrally, i.e., monolithically, with the second part 120 to convey the substance P coming from the pot 111 toward the recess 190. The substance P coming into contact with the inside surface 191 of the applicator element 103 may serve to feed the applicator element.
In
Naturally, the invention is not limited to the embodiments described above.
For example, the outside shape of the closure cap, of the first part 10, or of the second part 20 may be modified without thereby going beyond the ambit of the present invention.
For example, FIGS. 37 to 49 show various examples amongst others of possible shapes for the cap 5, for the first part 10, and for the second part 20.
The possible shapes may vary along the longitudinal axis Y or along any transverse axis, for example.
The shapes shown in FIGS. 37 to 49 are equally applicable to the embodiments of FIGS. 31 to 36, with the reference symbols 5, 10, and 20 being replaced by 105, 110, and 120, respectively.

The first part 10 may have a double wall, with an outer wall 99 and an inner wall 11, for example, having different bottom cross-sections.
For example, the outer wall 99 may have a cross-section that may be substantially square or rectangular, as shown in
The second part 20 may also have a double wall, having an outer wall 410, and the outlines of the walls 99 and 410 may coincide in certain angular positions only of the first part relative to the second part, as shown in
The second part 20 may have an outer covering 95, for example, made of elastomer, as shown in
In
In
Portions in relief may be formed on the outer skirt 21 of the second part 20, for example, fins 96 as shown in
It may be also possible to cover one and/or the other of the first and second parts 10 and 20 with a double wall 97, as shown in
The cross-section of the first and/or second part may have a variety of shapes at at least one point along the axis Y, for example, generally circular as shown in
Within a single device, the cross-section of the first and/or the second part may vary along the longitudinal axis X.
For example,
Such variation in the shape of the cross-section of the receptacle while having a circular junction between the first and second parts may make it possible to provide a receptacle of original shape without harming sealing, and may make it easier to grasp the first and second parts to turn one relative to the other.
In
Whatever the shape of the receptacle, the closure cap 5 may include a locking system that enables the cap 5 to be held substantially stationary relative to one of the first and second parts. Because of the locking system, the cap 5 may not become unscrewed when the first part 10 turns relative to the second part 20. This may make it easier for the user to turn one of the parts.
For example, and as shown in
To unscrew the closure cap, the pawl must escape from the ratchet 420 in the opposite direction. The force that must be exerted in order to enable the pawl to escape in the opposite direction may be greater than the force needed to turn one of the parts relative to the other. Thus, the user may make use of the closure cap as a handle for causing the first part to turn relative to the second part in one direction only or in a plurality of back-and-forth movements, depending on the desired result. Thereafter, to proceed with application, the user may turn the cap more strongly while holding the two parts 10 and 20 stationary relative to each other so as to cause the pawl to escape from the ratchet. Where appropriate or desired, some additional action may need to be exerted on the cap to make it possible and/or easier to cause the pawl to escape from the ratchet. For example, a force may be exerted axially on the cap, depending on the configuration of the ratchet and of the closure cap.
In an exemplary embodiment shown in
When the user presses the pushbutton 220 and turns the second part 20 relative to the first part 10, the closure cap 5 may remain secured to one of the parts and may not become unscrewed.
The second part 20 may include an outer portion 75 with a neck 22 having an outside thread, onto which the closure cap 5 may be screwed.
The bottom of the neck 22 may be connected to a shoulder 225.
The wiper member 30 may rest on the top edge of the neck and may include an annular holding lip 230 that bears against the underside of the shoulder 225.
The wiper member 30 may include a wiper lip 231 extending inward and, in the exemplary embodiment shown, with the device being in the closed position, the wiper lip 231 may bear against the stem 4 of the applicator 2.
The outer portion 75 may include a generally cylindrical portion 232 extending downward under the shoulder 225 in line with the closure cap 5.
This cylindrical portion 232 may be fluted internally so as to make it easier to keep the inner portion 76 firmly secured against moving inside the outer portion 75, for example, with clamping in the cylindrical portion 232.
The inner portion 76 may carry the blade 23 in the exemplary embodiment described.
The bottom of the generally cylindrical portion 232 may be connected to a portion 311 of generally hemispherical shape, including a circularly cylindrical surface 310 against which a sealing lip 14 of the second part 10 may bear.
As shown, the portion 311 may include an internal angular groove 312 into which the first part 10 may snap-fasten.
The first part 10 may be made as a single piece in the exemplary embodiment shown, for example, by molding a plastics material.
For example, the applicator element 3 may be a mascara brush, but may be any other type of applicator element without going beyond the ambit of the invention.
For example, the applicator element 3 may be an endpiece with a greatest transverse dimension that may be less than the diameter of the rod, as shown in
As shown in
In the exemplary embodiment of
The device of
For example, the applicator element 3 may comprise a flocked grid 241 secured to the top end of the neck, which may include an outside bead 240 onto which a corresponding annular groove of the closure cap 5 may snap-fasten.
The grid 241 may preferably be dispensed at an angle to make it easier to apply the substance to the lips, for example.
On turning the first part 10 relative to the second part 20, the substance may be brought toward the applicator element 3 via a chimney 245, and may move to the outside through an annular groove 246, as shown in
The grid 241 may have a variety of shapes, and may optionally be flocked in full or in part, as shown in
The applicator element 3 may comprise an elastomer, for example, a thermoplastic elastomer, that may be provided with one or more orifices 320, as shown in
The device shown in
For example, the second part 20 may include a blade 23 with a bottom portion 341 that may be curved simultaneously downward, inward, and rearward, given the direction of rotation of the blade 23 as represented by the arrow, such that turning the blade 23 may expel the substance toward a central region 344 into which the bottom of the dip tube 340 opens.
To ensure that the parts turn relative to each other in a determined direction R, an elastically deformable tab 350 carrying a pawl 351 may be made with the second part 20, for example, the pawl 351 pressing against ratchets 352 configured in such a manner as to prevent turning in the opposite direction.
In the exemplary embodiment described, the ratchets 352 may be made so as to extend in the annular groove 312 of the second part.
As shown in
Turning the first part 10 relative to the second part 20 may then make it possible to mix the substance with the component inserted in this way and to make the mixture uniform.
This may make it possible, for example, to add an oil to a lipstick that was poured in while hot when filling the device.
It would not go beyond ambit of the present invention for the blade 23 and/or the partition 16 to be of some other shape. For example, the thickness of the blade 23 and/or of the partition 16 may be different. For example, the blade 23 and/or the partition 16 may have a cross-section of shape that may be generally triangular, rectangular, or otherwise.
Nor would it go beyond the ambit of the present invention for the applicator element to have some other shape. For example, the applicator element may in the form of a paintbrush, a comb, or some other form.
For example, FIGS. 72 to 76 show other examples of applicator elements.
For example, the applicator element may be hollow, as in the examples of
The applicator element 3 of
In
As shown in
The applicator element 3 shown in
One of the parts 10 and 20 may include a plurality of blades 23, for example, two diametrically opposite blades 23, as shown in
A gap 414 may be left around the applicator element 3 so that after the parts have been turned relative to each other, a film of substance may remain around the applicator element 3. The film may be relatively thick.
The neck may include a wiper lip 415. This lip may be made integrally, i.e., monolithically, with the blade 23, or in exemplary embodiments may comprise a separate fitted piece. The device may contain a plurality of phases of substance that need to be mixed together prior to use.
The wiper lip 415 may also be omitted.
The inside space 425 may contain, for example, a plurality of phases P1, P2 that need to be blended into a uniform mixture at the moment of utilization by turning the second part 20 relative to the first part 10.
The various phases may be cast in succession while the device may be being filled.
The device of
FIGS. 82 to 84 show another exemplary embodiment of a device according to the invention.
In this device, the applicator may be off-center relative to the axis of rotation Y The applicator may include an applicator element 3, for example, a brush as in the exemplary embodiment shown, which may be received in an off-center housing 450. For example, the housing may have a perforated wall 451 so as to allow the substance P to pass therethrough when the blade 23 driven by the second part 20 turns inside the device.
For example, the wall 451 may have a series of longitudinal slots 453.
The housing 450 may also be made differently and the wall 451 may have different perforations. In the exemplary embodiment shown in
If so desired, and in any of the devices, the wiper member may be made using a porous material that may be elastically deformable, such as a block of open-celled foam, as shown in
The characteristics of the various exemplary embodiments of the invention may be combined with one another in other embodiment that are not shown.
All types of material may be used for making the various portions of the device, for example, the first and second parts and the cap. For example, portions of the device may be made of glass, metal, wood, plastic materials, singly or in combination, so as to obtain a desired or required conservation of the substance.
The substances contained in the device may be care substances, makeup, dermatological substances, or hair care substances, for example.
Exemplary embodiments of the invention make it possible to mix substances that are not miscible or that are traditionally not used in such applications because they comprise two or three phases to be mixed together.
The device may enable the mixture to be made uniform by turning the first and second parts relative to each other. Thus, new substances may be used, for example, for makeup, providing new makeup effects, or better staying power, or other properties that are new or improved.
A substance that may be pasty or even solid may be cast while hot or cold into the device during initial filling, for example, and then some other substance may be added, as mentioned above, such as a liquid, for example, a silicone gum, a silicone oil, or polybutylene, with the substances being mixed together by the device to deliver a final substance that may be uniform.
A plurality of ingredients that are unstable and/or incompatible may be introduced while hot or cold into the device during its initial filling or subsequently, thus making it possible to obtain substances delivered by the device that have rheology or other properties that are difficult to obtain otherwise.
The substance contained in the device may be heated prior to use, for example, in a microwave oven, to improve the behavior of the substance, for example. Moving the two parts of the receptacle relative to each other may make it possible to achieve a uniform temperature prior to application.
Throughout the description, including in the claims, the term “comprising a” should be understood as being synonymous with “comprising at least one” unless specified to the contrary.
