The present invention relates to cosmetic articles, and, in particular, to articles of manufacture and methods of use of such articles that shapes and/or defines a tip portion of a cosmetic unit that has become worn.
Certain cosmetic articles comprise cosmetic units made of readily deformable solid or semi-solid material whose tips become worn in use. Typically, the tip or a portion of the tip loses its point. In addition, or instead, the tip may become irregularly shaped having areas where the material has accumulated while other areas have material removed.
A worn tip will fail to provide precise and consistent application. Rather, lines made by the tip will be wider than intended, accumulated areas will produce blotched area on the consumer, and removed areas will fail to leave a cosmetic on the consumer.
Knowledgeable consumers will shape the tip using a tissue or other means. The result may be only marginally more desirable than the worn tip as physically unstable tip portions are formed.
To improve on this, cosmetic manufacturers provide shapers in cosmetic articles. Known shapers are removably provided in an end of a holder opposite to the tip. Consumers must remove the shaper from tile distal end, reorient the holder, shape the tip, evaluate the result, and, if satisfactory, replace the shaper in the distal end of the holder.
In related cosmetic articles of pencils, a shaper is known to be placed on a cap. A holder includes a solid cosmetic unit. The holder is secured in a cavity of the cap at proximal end of the cavity until the consumer wishes to use the product.
The holder is then removed and if sharpening is desired, the cap is turned so that a second end, the distal end, is opposite the tip of the holder. The holder is then inserted into a second cavity and as is well known in the art a sharpening blade removes a portion of the pencil and the cosmetic unit to provide a sharp tip. However, to prevent injury from the sharp blade, a second cap typically covers the cap adding yet a further step to the process.
Each product lacks the inherent convenience of a shaper disposed in the cap to shape and/or define a portion of the tip of tile cosmetic unit.
As used herein, a cosmetic article refers to an article of manufacture used by a consumer that includes a cosmetic unit and a holder, for example, a lipstick that has a holder and lipstick unit. Cosmetic unit refers to an article of manufacture that includes a cosmetic agent that is applied to the body of the consumer.
A shaper for defining a tip portion of a cosmetic unit that has become worn which includes a shaping surface for smoothing a surface of the tip portion and a slot in tile shaping surface. The shaping surface is user-selectably placed in contact with the tip portion. An edge disposed at the slot and is engageable for removing material of the tip portion when the shaping surface is in contact with tip portion. The removed material is passed through the slot.
Another object of the invention is a shaper for defining a tip portion of a cosmetic unit that has become worn which includes a reservoir for holding a shaping chemical, which interacts with a cosmetic material of the cosmetic unit. The shaper also includes a shaping surface for transmitting the shaping chemical to the tip portion to smooth a surface of the tip portion. The shaping surface may be user-selectably placed in contact with the tip portion.

In accordance with one embodiment of the present invention, a cosmetic article 10 includes a holder 12 and a cap 14 that shapes and/or defines a tip portion of a cosmetic unit held by the holder.
Cosmetic article 10 may be any suitable article as one skilled in the art will recognize from the description further herein. In particular, but not exclusively, cosmetic article 10 may be a full-line lipstick, a slim-line lipstick, a trim-line lipstick, an eye shadow, a concealer, a lip liner, an eye liner, a mechanical pencil, or any other suitable article.
Thus, holder 12 may have any suitable shape that is convenient for the user, that is suitable for holding the cosmetic unit, and/or that is desired for any reason. For example, holder may be circular in cross-section and have a small diameter for a lip liner or have a larger diameter for a lipstick. Thus, when holder 12 is a pencil, holder 12 may be polygonal in cross-section, or, for example, holder 12 may be rectangular when it is configured as a full-line lipstick.
The holder comprises a body 12a that firmly holds cosmetic unit 16 as is known in the art.
Holder 12 will maintain a tip 16a of the cosmetic unit exterior to a proximal end of body 12a so that a consumer can apply the cosmetic agent of the cosmetic unit to the consumer's body.
Cosmetic unit 16 may be a solid or semi-solid that permits a portion of the tip to be shaped and/or defined to correct the surface when material is unevenly distributed in the tip. For example, as illustrated with respect to
Preferably, the material has properties that permit correction in shape. Thus, when a surface that is less flexible than the material of the cosmetic unit is applied to the cosmetic unit and the cosmetic unit rotates relative to the surface, material moves from the areas of accumulated material to areas of removed material or is removed from the cosmetic unit. Similarly, cosmetic unit 16 is preferably response to heat and/or chemical such that material moves from the areas of accumulated material to areas of removed material or is removed from the cosmetic unit.
Because cosmetic article 10 may be any suitable article, cosmetic unit 16 may have any suitable shape. As illustrated with respect to
Returning to
With respect to
Cap 14 further includes a shaper 18 that shapes and/or defines a tip portion of a cosmetic unit that has become worn. Shaper 18 may be provided by any suitable means in the cap; for example, the shaper may be integral to the cap or it may be inserted and secured by frictional fit or by snap assembly.
Shaper 18 includes a shaping surface 18a in the form of a substantially conical or frustroconical surface. The angle of the conical surface may be any suitable angle for the particular material to be shaped and/or defined. Surface 18a may be constructed as a cone as shown in
Shaper 18 may include a shoulder 18b as shown in
Surface 18a may include one or more slots 18c each of which is defined by one or a pair of single-sided or double-sided edges 18d that remove a portion of the material of the tip. The material that is removed preferably exits to an inner space 14b of the cap. Space 14b is preferably suitably sized to retain the accumulated removed material.
In use, when the consumer wishes to apply the cosmetic agent, the holder and cap are moved relatively to each other. The user rotates the cap a predetermined amount before removing the holder from the cap. During the rotation, the shaping surface is moved over the tip and smoothes the outer surface of the tip. Excess material may be drawn off through the slot and/or is smoothed by moving material from an area of accumulated material to an area of reduced material.
To aid in turning the cap relative to the holder, inner portion 14a and shoulder 12b may be threaded and accordingly engageable. Thus, the shaper 18 may be engaged when the cap is placed on the holder when the consumer has finished the use of the cosmetic article, and also when the cap is removed to use the article.
Yet, inner portions 14a and shoulder 12b may also be threaded, but the cap may be fit on the holder without turning and removed with or without turning. Thus, the shaper is only engaged at times the consumer desires to do so.
In a further embodiment, with respect to
Shaper 18 may be located suitable rearward of the opening of the cap that when the holder is engaged in the cap, tip 16a does not make contact with the shaper. In that case, when the user wishes to shape the tip, the user engages the holder further into the cap, overcoming perhaps a retaining structure such as a low protrusion, and place the tip against the shaper. The longitudinal force exerted by the user on the tip via the holder determines the degree to which the tip contacts the shaper.
The user then rotates the holder relative to the cap by a predetermined amount causing the tip to rotate relative to the shaper. The shaping surface then is drawn over the tip and the outer surface of the tip is drawn off through the slot and/or is smoothed by moving material from an area of accumulated material to an area of reduced material.
With respect to
In accordance with a further embodiment of the present invention, as shown in
Cosmetic article 50 may be any suitable article as one skilled in the art will recognize from the description further herein. In particular, but not exclusively, cosmetic article 50 may be a full-line lipstick, a slim-line lipstick, a trim-line lipstick, an eye shadow, a concealer, a lip liner, an eye liner, a mechanical pencil, or any other suitable article.
Thus, holder 52 may have any suitable shape that is convenient for the user, that is suitable for holding the cosmetic unit, and/or that is desired for any reason. For example, holder may be circular in cross-section and have a small diameter for a lip liner or have a larger diameter for a lipstick. Thus, when holder 52 is a pencil, holder 52 may be polygonal in cross-section, or, for example, holder 52 may be rectangular when it is configured as a full-line lipstick.
The holder comprises a body 52a that firmly holds cosmetic unit 56 as is known in the art.
Holder 52 maintains a tip 56a of the cosmetic unit exterior to a proximal end of body 52a so that a consumer can apply the cosmetic agent of the cosmetic unit to the consumer's body.
Cosmetic unit 56 may be a solid or semi-solid that permits a portion of the tip to be shaped and/or defined to correct the surface when material is unevenly distributed in the tip. For example, cosmetic unit 56 may comprise a material that becomes uneven with high spots and low spots on the surface. Preferably, the material has properties that permit correction.
Thus, when a surface that is less flexible than the material of the cosmetic unit is applied to the cosmetic unit and the cosmetic unit rotates relative to the surface, material moves from the areas of accumulated material to areas of removed material.
Cap 54 may be made of suitable material and may be made by any suitable process, including snap fit assembly. Cap 54 is preferably sized to fit on holder 52 and protect tip 56a from external forces. Cap 54 may be an integrated cap or a stand-alone cap.
Cap 54 includes an inner portion 54a that matches a shoulder 52b of the body of holder 52 to retain the holder by any suitable means, for example, by frictional fit.
Cap 54 further includes a shaper 58 that shapes and/or defines a tip portion of a cosmetic unit that has become worn. Shaper 58 may be provided by any suitable means in the cap; for example, the shaper may be integral to the cap or it may be inserted and secured by frictional fit or by snap assembly.
Shaper 58 includes a shaping surface 58a that is capable of being impregnated by or transmitting a shaping chemical disposed in a reservoir 60 that shapes the tip by removing a predetermined portion of the material of the tip. The surface may be in the form of a substantially conical or frustroconical surface and, preferably, a shoulder 58b that guides tip 56a. The angle of the conical surface may be any suitable angle for the particular material to be shaped and/or defined. Surface 58a may be constructed as a cone but it or may also be the surface of another structure, for example, a plug having a conical surface facing the tip.
Shoulder 58b is preferably sized to be larger than the cross-sectional diameter of the tip by a predetermined amount to guide the tip and retain it to surface 58a.
In use, when the consumer wishes to apply the cosmetic agent, the user rotates the cap a predetermined amount before removing the holder from the cap. Thus, the shaping surface is drawn over the tip and smoothes the outer surface of the tip. Excess material is drawn of through the slot.
To aid in turning the cap relative to the holder, inner portion 54a and shoulder 52b may be threaded and accordingly engageable. Thus, the shaper 58 may be engaged when the cap is placed on the holder when the consumer has finished the use of the cosmetic article, and also when the cap is removed to use the article.
Yet, inner portions 54a and shoulder 52b may also be threaded, but the cap may be fit on the holder without turning and removed with or without turning. Thus, the shaper is only engaged at times the consumer desires to do so.
To provide a supply of the shaping chemical, a reservoir 60, disposed in a convenient location, contains predetermined amount of the chemical. The shaping chemical may be any suitable chemical that interacts with one or more compounds in the cosmetic material to cause a physical change in the cosmetic material.
The reservoir may be provided adjacent to the shaper. Thus, a push button 62 may cause a predetermined amount of the chemical to be released.
Push button 62 is provided in cap 54 for selectively placing a shaping chemical via shaper 58 in contact with tip 56a. Push button 62 is movably secured to an aperture 54c through top 54d of the cap. A tactile surface 62a is connected to a piston 62b, which may include a biasing member 62c, that passes through the aperture. A piston surface 62d transmits the consumer's push to the reservoir, which in turn release a predetermined amount of the shaping chemical.
Shaping surface 58a may comprise a material that absorbs the shaping chemical and becomes impregnated by it. By contact with tip 56a, the cosmetic material changes material properties and by being turned by the consumer may be shaped.
In one or more embodiments, the shaping surface may have a plurality of apertures 58c or grooves 58d that permit the shaping chemical to directly contact tip 56a.
The construction of cap 54 may also utilize biasing members and be similar to
In a further embodiment, rather than using a chemical, one or more batteries 64 are provided and are initiated when the user advances the holder into the shaper causing the shaper to move relative to the cap and close a circuit. The batteries provide an electric current to heat a circumferential resistance heater plate 66. Heater plate 66 release a predetermined amount of heat that softens the tip and which by being turned by the consumer may be shaped.
Similar to
Therein, the slot may be shaped to be spiral. Thus, when the user rotates the holder relative to the cap, the tip is shaped by edges 19c. Since the slot has a spiral shape the degree of rotation may be less than that of slot 18c.
Preferably, slot 19b is at least spirally circumferential to permit the user instead of or in addition to rotational movement of the holder relative to the cap, i.e. shaper, to use longitudinal movement of the holder relative to the cap, i.e. shaper. When the user moves the holder relative to the cap longitudinally, the tip contacts the shaping surface and a predetermined amount of the outer surface of the tip is drawn off through the slot and/or is smoothed by moving material from an area of accumulated material to an area of reduced material.
In particular, as taught with respect to
In a further embodiment, as illustrated at least by
Shaper 21 may be made of a material having relative high frictional properties, such as pumice or a rough wax. In use, the user then rotates the holder relative to the cap by predetermined amount causing the tip to rotate relative to the shaper. The shaping surface then is drawn over the tip and the outer surface of the tip is worn down and/or is smoothed by moving material from an area of accumulated material to an area of reduced material. Preferably, the user has oriented the cosmetic article such that the residue of material that is worn off falls into inner space 14b and may be removed via a lid 14e in cap 14 hinged by any suitable means including, as is generally known in the art, with a living hinge 14g.
As can be readily appreciated, shaper 21 may be suitable used in the structures taught with respect to
It should be understood that the above described invention may also be used as a stand-alone unit and need not be incorporated into a cap or may be incorporated into a distal end of the holder.
In one or more embodiments of the present invention, a plurality of shapers 30a-30e, shown here to be similar to shaper 18, although any shaper taught in the present application such as shaper 19, 21, 58, and 68 may also be suitable, are provided as shown generally in
Each of the plurality of shapers may be provided in an assembly that permits easy and safe insertion and removal from the cap. In addition thereto, or instead of, each of the plurality of shapers may be provided in its own cap. A selection of caps having a different purposed shaper may be provided with a cosmetic article or may be provided separately to permit the user the greatest possible flexibility in the use of one or more cosmetic articles.
Each shaper or shaper provided with a cap may comprise a unique identifier that is suitable for a user to recognize the shape.
In accordance with one embodiment of the present invention, a cosmetic article 100 includes a holder 102 and a cap 104 that shapes and/or defines a tip portion of a cosmetic unit held by the holder.
While cosmetic article 100 may be any suitable article; tile cosmetic article preferably is configured to have a cosmetic unit that includes a chisel point tip.
Holder 102 comprises a body 102a that firmly holds cosmetic unit 106 as is known in the art. Holder 102 maintains a tip 106a of the cosmetic unit exterior to a proximal end of body 102a so that a consumer can apply the cosmetic agent of the cosmetic unit to the consumer's body.
Cosmetic unit 106 may be a solid or semi-solid that permits a portion of the tip to be shaped and/or defined to correct the surface when material is unevenly distributed in the tip as previously discussed and having material properties that permit shaping, i.e. correction.
Cap 104 may be made of suitable material and may be made by any suitable process, including snap fit assembly. Cap 104 is preferably sized to fit on holder 102 and protect tip 106a from external forces. Cap 104 may be an integrated cap or a stand-alone cap.
With respect to
Cap 104 further includes a shaper 108 that shapes and/or defines a tip portion of a cosmetic unit that has become worn. Shaper 108 may be provided by any suitable means in tie cap; for example, the shaper may be integral to the cap or it may be inserted and secured by frictional fit or by snap assembly.
