This non-provisional application claims the benefit of French Application No. 04 04674 filed on Apr. 30, 2004, and U.S. Provisional Application No. 60/572,482 filed on May 20, 2004.
BACKGROUNDThe present invention relates to packaging and applicator devices, for example, for making up skin, mucous membranes, nails or hair.
Known devices for packaging and dispensing lipsticks or deodorants comprise a body housing a stick of substance and a mechanism for displacing the stick of substance relative to the body to compensate for wear as the stick of substance is used up. The drive mechanism is relatively expensive and an applicator surface of the stick of substance never regains its original shape.
Makeup pencils are also known that comprise a wood or plastics body into which the substance is cast to form the “lead.” During use, the “lead” becomes worn and a user must resort to a pencil sharpener to reshape the “lead,” which risks breaking the “lead” or weakening the “lead” for subsequent use.
SUMMARYKnown blushers, lip colors, or eye shadows that are slightly domed for direct application to skin suffer from a disadvantage of losing their initial shape relatively rapidly; once shape has been lost, application may no longer be as accurate as desired.
The invention aims, for example, to overcome such disadvantages.
Exemplary embodiments of the invention provide a packaging and applicator device comprising: a body; a block of fluidizable substance that is stationary relative to the body while the substance is in a solid state, said block of substance projecting beyond the body to define at least one surface comprising an applicator surface; and a reshaper member for reshaping the applicator surface. The reshaper member may be positionable on the body to co-operate therewith to define at least one cavity into which the substance may flow when fluidized by supplying heat. The substance thus may retain a shape of the cavity when the substance returns to the solid state after cooling.
The term “fluidizable” should not be construed in a narrow sense, and encompasses any possibility of softening a substance under the effect of heat which is sufficient to allow the substance to flow into said cavity to reshape the applicator surface thereof.
The term “solid state” means the state of the substance at ambient temperature (about 20° C.) under normal conditions of use.
The term “stationary relative to the body” means that the device has no drive mechanism for displacing the block of substance axially relative to the body when the substance is at ambient temperature, such as, for example, known screw mechanisms in certain deodorants or lipsticks.
In exemplary embodiments, the reshaper member may be arranged to allow the body of the device to remain vertical as the substance flows into the cavity. For example, the reshaper member may be arranged to rest in a stable manner on a horizontal flat surface.
In exemplary embodiments, the reshaper member may be arranged to engage on an outside of the body. For example, the reshaper member may also act as a member for closing the body, at an applicator surface end thereof, for example, to protect the applicator surface when not in use. The reshaper member may optionally be configured to be fastened on the body on an end opposite the applicator surface, which may, for example, reduce a risk of losing the reshaper member while the substance is being applied.
In exemplary embodiments, the body may include an inside surface in contact with the substance. The inside surface may comprise at least one portion in relief that opposes slipping of the substance inside the body when the substance is in the solid state. Said portion in relief may comprise a constriction or serration, for example.
In exemplary embodiments, the body may include an inside cross-section that tapers or flares toward the applicator surface, for example, decreasing or increasing in internal cross-section toward the applicator surface.
In exemplary embodiments, the reshaper member may comprise at least two portions to define cavities with different shapes, for example, configured to reshape the applicator surface into different respective shapes, depending on which portion the user selects to co-operate with the body of the device. This may afford the user the opportunity to choose between a plurality of shapes of the applicator surface, depending on the type of makeup being applied.
In exemplary embodiments, the reshaper member may comprise one housing to reshape the applicator surface and another housing to enclose the body. The other housing may not act to reshape the applicator surface. The other housing may, for example, co-operate with the one housing to close around the body.
If appropriate or desired, the body may include more than one opening configured to allow the substance to flow therethrough when fluidized by applying heat, for example, during reshaping of the applicator surface.
In exemplary embodiments, the body may include at least one eccentric opening configured to allow the substance to flow therethrough when fluidized by applying heat, for example, during reshaping of the applicator surface.
If necessary or desired, the body of the device may be packaged in a package such as a case with a portion that act as the reshaper member. For example, the reshaper member may comprise a package configured to house the body of the device.
In exemplary embodiments, a quantity of substance contained in the body of the device is sufficient to allow at least one reshaping operation. For example, the quantity may be sufficient to allow at least two reshaping operations.
A temperature to which the substance is heated for reshaping the applicator surface may, for example, depend on a nature of the substance and a rate at which a missing portion thereof may fill in the cavity defined by the reshaper member.
For example, the substance may comprise an anhydrous formulation that behaves reversibly as a function of temperature. The substance may contain at least one compound that coagulates, plasticizes, or hardens on returning to ambient temperature.
For example, the substance may comprise a blusher, a lipstick, or an eye makeup substance. Such examples are non-limiting, the invention being applicable to any cosmetic or dermatological care product, for example.
In exemplary embodiments, the body of the device and the reshaper member may be configured to withstand a rise in temperature necessary to fluidize the substance and reshape the applicator surface. For example, the body and the reshaper member may be configured to withstand a temperature of about 120° C. in the absence of mechanical stresses.
In exemplary embodiments, the reshaper member may be made so as to facilitate unmolding of the applicator surface. A material of which the reshaper member is made may be provided to this end. The reshaper member may, for example, be made of polypropylene (filled or otherwise), polystyrene, polyamide, such as Nylon®, polyethylene terephthalate (PET), elastomers, or silicones, such examples being non-limiting.
In exemplary embodiments, the reshaper member may be made of at least two different materials, one of which may be elastically deformable. The reshaper member may, for example, be made with a bottom formed of an elastically deformable material, such as silicone, to facilitate unmolding, with a remainder being formed of a non-elastomeric material, such as polypropylene.
In exemplary embodiments, the reshaper member may include a vent, for example, to facilitate filling the cavity.
In exemplary embodiments, opposite the reshaper member, the body may include an opening to allow pressure equalization.
Exemplary embodiments of the invention provide a method of reshaping an applicator surface in a device comprising: a body, a block of liquefiable substance contained in a solid state in the body, said block of substance projecting beyond the body to define at least one surface for application; and a reshaper member for reshaping the applicator surface, said reshaper member being positionable on the body to co-operate therewith to define at least one cavity, the method comprising: after the block of substance has been used at least once, positioning the reshaper member on the body; heating the substance to allow the substance to flow into the cavity; and allowing the substance to cool with the reshaper member positioned on the body, the substance retaining a shape of the cavity on resuming the solid state after cooling.
In exemplary embodiments, the substance may be heated by exposing the substance to microwave radiation, for example, for a period in a range of about 10 seconds to about 5 minutes. Alternatively, in exemplary embodiments, the substance may be heated by exposing the substance to heat generated by an electrical resistance. The substance may be heated to a temperature of more than about 80° C., for example.
In exemplary embodiments, the cavity into which the substance flows may be selected from a number of cavities as a function of a desired shape with which the applicator surface is to be endowed.

DETAILED DESCRIPTION OF EMBODIMENTS An exemplary packaging and applicator device 1 shown in
In this exemplary embodiment, the applicator member 10 may constitute a pencil. Prior to first use, the applicator surface 14 may have a generally pointed shape.
An end 15 of the body 12 adjacent to the applicator surface 14 may be substantially conical, converging toward the applicator surface 14. The body 12 may be open at an opposite end 16, for example. For example, the substance 13 may be cast into the body 12 via the opposite end 16 during manufacture of the device 1.
In this exemplary embodiment, the reshaper member 20 may be in a general shape of a cap comprising a tubular skirt 21 that connects at a lower end thereof to a bottom portion 22, as shown in
In this exemplary embodiment, the skirt 21 may be cylindrical and centered about the axis X. The skirt 21 may include an inside diameter that is adapted to an outside diameter of the body 12, for example, so that the skirt 21 fits on the body 12 with a small amount of interference.
The reshaper member 20 may define a cavity 24, defined radially by the skirt 21 with a bottom portion 25 providing a shape corresponding to that with which the applicator surface 14 is to be endowed when reshaped.
Before first use, the applicator surface 14 may have a shape that corresponds to that of the bottom 25 of the cavity 24. The substance 13 may advantageously be initially cast into the body 12 while the reshaper member 20 was in position thereon, for example, as illustrated in
After being used one or more times, the applicator surface 14 may become worn due to transfer of substance onto the treated surface and may, for example, obtain a flattened shape shown in
The user may then apply heat, with the applicator member and the reshaper member 20 disposed vertically as shown, for example, by placing the assembly in a microwave oven. A duration of heating depends on several factors such as a power of the oven and natures of the body, the device and the substance.
The substance 13 may be heated to a temperature higher than about 80° C., for example. The body 12 of the applicator member 10 and the reshaper member 20 may be configured to withstanding the temperature to which the substance is heated.
The applicator member 10 and the reshaper member 20 may be made so as to be compatible with use in a microwave oven. For example, the applicator member 10 and the reshaper member 20 may avoid inclusion of any metal or metallization which could deteriorate or damage the oven being used.
Properties of the substance 13 may be such that, when heated to a sufficient temperature, the substance 13 fluidizes and flows under gravity into the cavity 24 to match the shape of the bottom 25, for example, as shown in
The user may then allow the substance 13 to cool, to allow the substance 13 to solidify. Cooling may, for example, be accomplished in ambient air or by placing the assembly in a refrigerator or a freezer. As shown in
Once the substance 13 has resumed the solid state, the user may once again use the applicator member 10, with the applicator surface 14 having regained a suitable or desired shape, corresponding to that of the bottom 25.
Such operation may be repeated as many times as allowed by a quantity of substance 13 contained in the body 12. A maximum volume of substance 13 that flows out on each reshaping of the applicator surface 14 into the cavity 24 may, for example, correspond to less than half of an initial volume of the block of substance 13, preferably less than a third, a quarter, a fifth, or a tenth thereof.
Each time the applicator surface 14 is reshaped, heating of the substance may be sufficient to exert a germicidal or bactericidal action on the applicator surface 14, which may serve to reduce or even dispense with preservatives in the substance.
To reduce a risk of the block of substance 13 slipping relative to the body 12 when the substance is in the solid state, an inside surface 17 of the body 12 may be provided with at least one portion in relief, which may be a hollow or a projection, for example, as shown in
As shown in
It is also possible to provide the inside surface 17 with a cross-section that is not constant, for example, a cross-section that decreases toward the end 15, as shown in
If appropriate or desired, the inside surface 17 may be made with a cross-section that increases or decreases toward one end of the body 12 and also provided with at least one portion in relief to encourage retention of the substance 13.
The reshaper member 20 may act as a closure cap to protect the applicator surface 14 when not in use, for example, as shown in FIGS. 1 to 4. Alternatively or additionally, the reshaper member 20 may include a second portion defining a cavity 32 that differs from the portion defining the cavity 24. The second portion may serves only to receive the body 12 when not in use, the cavity 24, but not the cavity 32, being the suitable for reshaping the applicator surface 14. In such case, the cavity 32 may, for example, be sufficiently wide to avoid contacting the reshaper member 20 with the applicator surface 14, as shown in
If appropriate or desired, as shown in
As shown in
The reshaper member 20 may, if appropriate or desired, and as shown in
The cavities 24, 24′ and 24″ may include respective bottoms 25, 25′ and 25″ with different shapes, for example, to allow different applicator surface shapes to be formed, such as points with different tapers.
The applicator member 10 may differ from a pencil. For example,
The body 12 of the applicator member 10 in this exemplary embodiment may comprise a tubular portion 40 that is connected at a bottom thereof to a flange 41 that is directed radially outwardly. As shown, the flange 41 may be provided with an edge 42 that is directed toward the end 16 of the applicator member 10 remote from the applicator surface 14.
As shown in the exemplary embodiment of
As shown, the body 12 may comprise a one-piece plastics molding. However, the present invention contemplates the body 12 being made by assembling a plurality of elements that have been made independently as well.
The reshaper member 20 may comprise a wall 46 in the form of a cup. The wall 46 may define a cavity 24 with a bottom 25 having a shape that is to be restored to the applicator surface 14.
A periphery of the wall 46 may be connected to a tubular skirt 47 via which the reshaper member 20 may rest on a horizontal surface disposed between the wall 46 and the skirt 47, with an axis of the cavity 24 disposed vertically. The skirt 47 may be extended upward by a rib 48 that, by cooperating with the edge 42, may center the applicator member 10 on the reshaper member 20, as shown in
During use, the applicator surface 14 may lose the initial shape, as shown in
Contact between the flange 41 and the wall 46 may contribute to preventing substance from leaking out while the substance is in the fluid state. Specific sealing means may be provided, such as at least one sealing lip or gasket formed of a particular material, such as, for example, an elastomer.
The present invention contemplates that the applicator member 10, as well as the reshaper member 20, may be made in a variety of manners.
For example,
In the exemplary embodiment shown in
In the exemplary embodiment shown in
The body 12 may include a single opening 45 through which the substance 13 may flow when in the fluid state to allow the applicator surface 14 to be reshaped. Said opening 45 may be centered on a longitudinal axis of the applicator member 10. Such axis may be an axis of symmetry, for example. Alternatively, as shown in
The applicator member 10 may also include a plurality of openings 45 through which the substance 13 may flow during reshaping of the applicator surface 14, as shown in
As shown in
One of the materials may define at least the bottom of the cavity, while the other material may form a remainder of the reshaper member.
The invention is not limited to the embodiments described above; for example, characteristics of the various embodiments described may be combined together.
The substance may be heated to fluidize the substance in a manner other than by placing the applicator member in a microwave oven, for example, by exposing the substance to heat generated by an electrical resistance. Such electrical resistance may be external to the applicator member or, if appropriate or desired, may be integrated in the applicator member. In such embodiments, the reshaper member may comprise a source of electrical energy and means for establishing electrical contact with the resistance incorporated in the applicator member, so that positioning the applicator member on the reshaper member allows or automatically causes an electric current to flow in the resistance, heating the substance and reshaping the applicator surface.
Throughout the description, the expression “comprising a” should be understood to be synonymous with “comprising at least one”, unless otherwise indicated.
Although the present invention herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention.
