technical field

The present disclosure relates generally to a cosmetic applicator for applying a product comprising a cosmetic, care or pharmaceutical to a keratin matrix such as the skin, lips, under the eyes, eyebrows, eyelids, cheeks, nails or any other part of the body. . In particular, the present disclosure relates to an applicator for cosmetics that provides a container for holding a cosmetic product, an applicator head comprising a surface for distributing the product to a keratinous surface, and a mechanism for transferring the product from the container to the surface.

There is a device for dispensing cosmetic or pharmaceutical products. Such devices generally consist of a container for carrying the cosmetic or medicinal product, a delivery mechanism for displacing the cosmetic or medicinal product, and an applicator. For example, in the medical industry, applicators are used to apply medicines, such as ointments, to body parts. In the cosmetic and personal care industry, applicators are used to apply lipsticks, lip balms, skin creams, lotions, and other cosmetic products to body parts.

Many cosmetic products that are flowable or otherwise non-generating in shape are packaged and sold in containers in which the cosmetic is delivered and applied to the user's skin by a cosmetic applicator.

Generally, a cosmetic applicator is provided at the end of a stem carried by a cap that rests on the mouth or opening of the container and closes it, and the cosmetic applicator is immersed in the cosmetic material contained in the container when the cap is in the container closed position. The cap serves as a handle for the user when the cosmetic applicator with a certain amount of cosmetic is taken out of the container and applied to the skin.

In some cases, a flexible elastomeric wiper is mounted to the container opening to engage the cosmetic applicator as the cosmetic applicator is withdrawn through the opening to remove excess cosmetic product that may be carried by the cosmetic applicator from the body of the cosmetic within the container. .

The applicator may be immersed in the container containing the cosmetic material and then removed from the bottle to apply the product to the user's skin. Such an applicator can hold the cosmetic product by adhesion to the applicator surface. This limits the amount of product that can be delivered each time the applicator is removed from the bottle after immersion. It may be necessary to immerse the applicator several times in succession to deliver a sufficient amount of product to perform the entire application process. Accordingly, many prior art cosmetic applicators do not provide a location or area capable of holding a higher dose of cosmetic material in or on the applicator head. Due to the limited surface area and no location or area to hold a higher volume of cosmetic material, many prior art applicators result in fewer cosmetic applicator heads in containers for application processes such as covering lips with lip gloss cosmetics. cannot be inserted

Another conventional applicator includes an internally supplied applicator, in which case a quantity of cosmetic product is stored in a container in fluid communication with the applicator head. The product is transferred from the reservoir to the applicator head as application is performed. The product may be delivered, for example, by applying pressure to the reservoir to squeeze the product against the applicator head. In this way, it is possible to refill the applicator head without lowering the applicator and immersing it again in the cosmetic container. However, providing a reservoir in fluid communication with the applicator can add complexity and cost. Also, it can be difficult for the user to control the amount of product delivered to the applicator head. In addition, the amount of material held in the container in fluid communication with the applicator head may be limited by the dimensions of the applicator itself. Also, with known prior art applicators, only a small amount of product can be firmly held in the applicator head while the product is being applied to the skin. Also, known conventional applicators cannot provide a convenient surface for massaging the product onto the skin once applied.

Accordingly, there is still a need for a cosmetic package having an applicator that can apply a larger amount of product without re-immersing the applicator into the cosmetic container. There is also a need for a cosmetic applicator that can deliver a sufficient amount of cosmetic product to the skin of a user to treat a relatively large area and also provide a convenient surface for massaging the product onto the skin once applied.

The present disclosure provides embodiments of a cosmetic package that can be readily configured to include a product and a cosmetic applicator.

The present disclosure provides an embodiment of a cosmetic package having a cosmetic applicator that can apply a larger amount of cosmetic product without occasionally immersing the cosmetic applicator in the cosmetic container.

In alternative embodiments, the closure may be snapped into place on the neck of the receptacle, or any other type of mechanism may be used to fit the closure to the receptacle.

A wiper is provided inside the neck of the container to wipe off excess cosmetic product from the cosmetic applicator. According to one embodiment, the wiper comprises an annular bead on its outer surface for engaging a corresponding annular groove formed in the inner surface of the neck of the receptacle. The wiper includes a wiping orifice sized to mate with the applicator.

According to one embodiment, the receptacle and closure may be made of a rigid material such as glass, metal, rigid plastic, or any other material known in the art. In an alternative embodiment, the receptacle and closure are made of a flexible material, such as a flexible polymer material or any other material known in the art.

According to one embodiment of the present disclosure, the applicator head and stem are fitted together by a snap fitment. In an alternative embodiment, the applicator head and stem are fitted together by friction fit, gluing, crimping, self-engaging, and the like. According to some embodiments, the distal end of the stem includes an interior longitudinal cavity for receiving and holding the applicator head.

The shank portion is held at the distal end of the stem for applying the cosmetic product. A closure shaped to close the cosmetic container is retained at the proximal end of the stem. The distal end of the stem includes an internal longitudinal cavity for receiving and retaining the shank of the applicator head.

According to one embodiment, the application member is preferably formed from a thermoplastic urethane. According to a more preferred embodiment, the urethane is Desmopan® 487. In an alternative embodiment, the application member is formed from a suitable polymeric material or other material known in the art.

According to an embodiment of the present disclosure, the outer surface of the application member is covered with an application element composed of flocking fibers. The fibers for flocking may be any suitable material known in the art including nylon, polyester or natural fibers. The flocking fibers are applied with an adhesive such as epoxy to the surface to be flocked. The flocking finish to the outer surface of the application member can be achieved by appropriately selected known techniques such as electrostatic flocking. According to one embodiment, the outer surface of the application member before flocking is smooth and has no surface texture, that is, there is no wrinkle finish or matte finish. In other words, the outer surface of the application member before flocking is smooth and slippery, according to some embodiments.

Preferably, the flocking process takes place in an electrostatic field, which results in proper orientation of the fibers. The flock on the outer surface of the application member provides a layer capable of holding a small amount of cosmetic suitable for one or two applications. In alternative embodiments, the exterior of the application member may include injection molded fibers, protrusions, or grooves capable of holding the cosmetic product.

According to an embodiment of the present disclosure, the outer surface of the application member is covered by the flock coating. However, in an alternative embodiment, the outer surface of the application member is not covered by the flock coating.

According to an embodiment of the present disclosure, the application member includes a root portion having a cylindrical shape. According to an alternative embodiment, the root portion is circular or any other shape known in the art.

According to one embodiment of the present disclosure, the applicator head may be at least partially made of a material that is more flexible than the material from which the stem is made. According to one embodiment, the receptacle and cap may be made of a rigid material such as glass, metal, rigid plastic, or any other material known in the art. However, in alternative embodiments, the receptacle and cap may be made of a flexible material, such as a flexible polymer material or any other material known in the art.

According to one embodiment, instead of providing an applicator head configured to be pulled through a wiper from a container holding cosmetic material, the applicator head is mounted above the pump mechanism. The pump mechanism draws the cosmetic from the container accommodated in the cosmetic applicator. An internal passage in the applicator head is in fluid communication with the pump. When the pump mechanism is actuated, an amount of product is delivered to the head. The pump mechanism may be an airless pump, a squeeze tube, or a click pen.

According to a first embodiment of the present disclosure, there is provided a cosmetic applicator including an application member, the application member further comprising a root portion and a spatula extending from the root portion. The spatula extends from the root and has an elongate support extending along the longitudinal axis of the cosmetic applicator. The spatula has a first application surface and a second application surface opposite to the first application surface. The first application surface has a concave inner surface, while the second application surface has a convex outer surface. The concave inner surface creates a capacity reservoir. The convex exterior serves as a large blending surface for easy application of cosmetics. The spatula also has a first longitudinal edge and a second longitudinal edge. At least one of the first longitudinal edge or the second longitudinal edge extends in all three-dimensional space.

According to an embodiment of the present disclosure, the capacity reservoir on the concave inner surface of the first application surface serves as a reservoir for cosmetics. A significant amount of cosmetic product may be contained in such a dose reservoir which may be applied to the skin or keratin matrix of a user.

According to an embodiment of the present disclosure, the first longitudinal edge and the second longitudinal edge of the spatula are asymmetric with respect to each other. At least one of the first longitudinal edge or the second longitudinal edge extends in all three-dimensional space. In a preferred embodiment, both the first longitudinal edge and the second longitudinal edge extend in both three-dimensional space. In a preferred embodiment, the first longitudinal edge comprises a first curved outwardly convex and a second outwardly concave curve. When viewed from the proximal end to the distal end of the spatula, the first curve is followed by a second curve of the first longitudinal edge.

According to an embodiment of the present disclosure, the first and second curves of the first longitudinal edge differ from each other by a property of the curve or by a radius of curvature. According to the present disclosure, if the curve does not correspond to an arc, "the radius of curvature is measured at the vertex of the curve". A first curve is generated about a first axis of curvature with respect to a first radius of curvature. A second curve is created about a second axis of curvature for a second radius of curvature. According to a preferred embodiment, the first axis of curvature and the second axis of curvature are not parallel and extend in different directions. The first radius of curvature may or may not be the same as the second radius of curvature. In a preferred embodiment, the first radius of curvature is greater than the second radius of curvature so that the first curve extends to at least 75% of the length of the first longitudinal edge.

According to an embodiment of the present disclosure, the second longitudinal edge comprises a third curve that is convex outward, a fourth curve that is concave outward, and a fifth curve that is convex outward. Viewed from the proximal end to the distal end of the spatula, the third curve is followed by a fourth curve, followed by the fourth curve, followed by a fifth curve.

The third, fourth and fifth curves differ from each other by the property of the curve or by the radius of curvature. A third curve is created about a third axis of curvature for a third radius of curvature. A fourth curve is created about a fourth axis of curvature for a fourth radius of curvature. A fifth curve is created about a fifth axis of curvature for a fifth radius of curvature.

According to an embodiment of the present disclosure, the third, fourth, and fifth axes of curvature are not parallel and extend in different directions. The third, fourth, and fifth radii of curvature may or may not be the same. In particular, the third radius of curvature and the fourth radius of curvature may or may not be the same. In an exemplary embodiment, the fifth radius of curvature is smaller than the third and fourth radii of curvature. More specifically, at least one of the third curve or the fourth curve extends to at least 30% of the length of the second longitudinal edge. The fifth curve extends to at least 10% of the length of the second longitudinal edge.

According to one embodiment of the present disclosure, the first application surface has a recess substantially surrounded by a first longitudinal edge and a second longitudinal edge except for a proximal end of the spatula. A gap exists between the first longitudinal edge and the second longitudinal edge near the proximal end of the spatula. The recess serves to maintain the cosmetics. When the cosmetic applicator is applied to the keratin matrix, the cosmetic present in the recess can be deposited and the surface of the cosmetic product in contact with the lips or any other part of the body can be relatively large, thus making the lips or any other part of the body. The region can be masked relatively quickly. The recess extends longitudinally from the proximal end to the distal end of the spatula.

According to one embodiment of the present disclosure, the recess extends along a longitudinal axis that does not coincide with the longitudinal axis of the cosmetic applicator. More specifically, the recess is off-center with respect to the longitudinal axis of the cosmetic applicator and forms a non-zero angle with the longitudinal axis of the cosmetic applicator.

According to one embodiment of the present disclosure, the recess opens outwardly over the entire length of the spatula through the first application surface for use in applying cosmetic products.

According to a preferred embodiment, the recess extends more than half the width of the spatula when viewed at any point along the longitudinal axis. In an alternative embodiment, the recess does not extend more than half the width of the spatula.

According to one embodiment of the present disclosure, the width of the recess passes through the extreme between the proximal and distal ends of the spatula. For example, the extreme is the maximum. More specifically, when viewed from the front, the recess has its widest portion that gradually decreases in width from the widest portion to the proximal or distal end of the spatula.

According to a preferred embodiment, the recess may cross more than half the length of the spatula. In an alternative embodiment, the recess does not cross more than half the length of the spatula.

According to one embodiment of the present disclosure, the first longitudinal edge and the second longitudinal edge converge to form a narrow tip at the distal end of the spatula. The narrow tip aids in the accurate deposition of the cosmetic when applied to the user's skin or keratin matrix.

Also, according to one embodiment, the narrow tip does not coincide with the longitudinal axis of the cosmetic applicator. More specifically, the narrow tip is off-center with respect to the longitudinal axis of the cosmetic applicator.

According to an embodiment of the present disclosure, upon use of the cosmetic package, the user first separates the closure from the receptacle. To apply the product to a keratin matrix such as the skin, lips, eyelids, cheeks, nails, or any other part of the body, the cosmetic applicator may be immersed in the product in a receptacle and then applied by the applicator head.

According to an embodiment of the present disclosure, when the cosmetic applicator is taken out from the state immersed in the cosmetic, the cosmetic is picked up and held on the entire surface of the spatula.

According to one embodiment of the present disclosure, the widest portion of the spatula has a greater width than the widest portion of the wiper orifice. Thus, when the cosmetic applicator is withdrawn from the receptacle, the widest part of the spatula is caught in the wiper orifice of the wiper. In this embodiment, since the spatula is made of an elastically deformable material, it is deformed at the widest portion caught by the wiper orifice so as to pass through the wiper orifice.

Since the first application surface of the spatula on which most of the cosmetics are held has a concave inner surface, the spatula is curled into a substantially C-shape in which the first longitudinal edge and the second longitudinal edge approach each other. Because the spatula is curled into a substantially C-shape, the cosmetic remains inside the C-shape while the spatula is in a deformed state. On the other hand, the second application surface has a convex outer surface and is wiped with a wiper. The second application surface acts as a blending surface for easy application of the cosmetic which is dislodged and applied by the first application surface of the spatula.

The wiper is made of an elastically deformable material, so that both the spatula and the wiper orifice are deformed to reduce resistance to withdrawal and insertion, further improving ease of use.

After the spatula passes through the wiper orifice, it is restored to its original shape without any force applied by the wiper orifice. Accordingly, as the original shape is restored, the cosmetic is spread over the entire area of the first application surface of the spatula. As a result, the spatula can apply the cosmetic uniformly to the lips or any other part of the body. At this time, almost no cosmetics remain on the second application surface of the spatula, so that the user can safely and quickly apply the cosmetics without worrying about unintentional application other than the target site.

The wiper wipes off excess cosmetics attached to the spatula as well as cosmetics attached to the stem.

According to a second embodiment of the present disclosure, a cosmetic applicator includes an application member including a support and a wing extending from the support, the wing being curved about a transverse axis Y. The support supports the wing at the base portion of the wing and at one lateral edge. The wing has a concave front surface and an opposing convex rear surface. Further, the wing is curved about a transverse axis perpendicular to the longitudinal axis X of the application member, that is, the wing is curved from left to right so that the wing forms a longitudinal recess in the concave front surface of the wing.

According to another aspect of the present disclosure, there is provided a cosmetic package comprising a cosmetic applicator and a receptacle for holding the cosmetic product. The cosmetic applicator includes an applicator head, a stem, and a cap. The cap of the cosmetic applicator has a thread formed in the neck of the receptacle that can be threaded into the thread. an applicator head is held at the distal end of the stem to apply the product; A cap is retained at the proximal end of the stem.

In general, the use of the terms “distal” and “proximal” herein is assumed to mean that the distal side/end is the inside-facing side/end of the storage receptacle, whereas the proximal side/end refers to the removal opening of the receptacle. It means facing side or end.

The distal end of the stem also includes an internal longitudinal cavity for receiving and holding the applicator head. Also, a wiper is inserted into the neck of the receptacle to wipe off excess cosmetics from the cosmetic applicator.

Also, the applicator head of a cosmetic applicator may be used to apply a product, including a cosmetic or care product. Cosmetics or care products include viscous cosmetics, mascara, eyebrow powder, lip gloss, hair color, skin care, under-eye cosmetics, pharmaceuticals and similar products.

The applicator head includes an application member at its distal portion and a shank member at its proximal portion. The shank member is configured to be received and retained within the interior longitudinal cavity of the stem.

According to one embodiment of the present disclosure, the support extends in the longitudinal axis of the stem in the direction of the wing. The wing extends laterally from the support such that the support supports the wing laterally at both sides of the wing and at the base of the wing.

According to another embodiment of the present disclosure, the convex back surface of the wing provides a large blending surface for smooth and efficient application of cosmetic products. The application member picks up a generous amount of product from the concave front surface of the wing, so re-immersion is not required during application. More specifically, the longitudinal concave portion of the concave front surface of the wing facilitates retention of the cosmetic product. When the cosmetic applicator is applied to the keratin matrix, the cosmetic present in the longitudinal recesses of the wing may be deposited and the surface of the cosmetic product in contact with the lips or any other part of the body may be relatively large, and thus the lips or body may be relatively large. Any other portion of can be masked relatively quickly.

According to one aspect of the present disclosure, the longitudinal recess of the wing extends longitudinally from the proximal end to the distal end of the wing along a longitudinal axis that does not coincide with the longitudinal axis X of the application member/stem. More specifically, the longitudinal recess is off-center with respect to the longitudinal axis X of the application member and forms a non-zero angle with the longitudinal axis of the application member.

According to one aspect of the present disclosure, the support comprises two opposing major sides, a first front side, an opposing second back side, and two opposing sides, a third side and a fourth side. The third side is convexly curved along the longitudinal axis (X) and along an axis (Z) substantially perpendicular to the X and Y axes. Further, the fourth side comprises a convex curve followed by a concave curve when viewed from the proximal to the distal portion of the application member. The wings extend laterally from a fourth side of the support. The engaging edge of the wing is connected along at least a portion of the convex curved surface and the concave curved surface of the fourth side of the support body.

In alternative embodiments, the curves of the third and fourth sides of the support or the shape of the support may be different, so that the present disclosure is not limited by the curves of the third and fourth sides of the support or the shape of the support.

According to an embodiment of the present disclosure, the widths of the first and second rear surfaces of the support are continuously decreased from the proximal end of the application member toward the distal portion of the application member, when viewed in front and rear views of the application member. do.

Further, the width of the third side surface of the support body decreases continuously from the proximal end of the application member toward the distal portion of the application member when viewed from the left side view of the application member. More specifically, the support in the left side view of the application member has a shape curved convexly toward the tip of the application member and has a side edge inclined. The third side of the backing provides a narrow blending surface to align and blend cosmetic products, for example at the corners of the lips and eyes.

According to another embodiment of the present disclosure, the application member consists of an elastomer, in particular a thermoplastic elastomer. The wing is relatively thinner than the support. More specifically, the wing is at least two or three times thinner than the support. For that reason, the wing is particularly flexible and elastically bendable compared to the support. The wings are flexible enough to bend upon application along the contours of a person's facial skin or lips to provide a uniform coating of cosmetic products.

A swirled extension extends from the support to the concave front of the wing, providing strength to the wing during application. However, the swirl extension is an optional feature, and the application member may or may not include any such extension.

According to another embodiment of the present disclosure, the width of the wing first increases from the proximal end of the wing to form the widest portion of the wing and then gradually decreases from the widest portion to the distal end of the wing. A narrow tip is formed at the distal end of the wing coincident with the distal end of the application member. Also, the narrow tip at the distal end allows the user to draw precise lines during application. Also, the narrow tip at the distal end of the application member may not coincide with the longitudinal axis X of the application member. More specifically, the narrow tip is off-center with respect to the longitudinal axis (X) of the cosmetic applicator.

According to another embodiment of the present disclosure, the widest portion of the application member coincides with the widest portion of the wing.

According to one embodiment of the present disclosure, at least one of the wings and the support may be flocked.

According to an alternative embodiment of the present disclosure, the application member may not be flocked.

According to a preferred embodiment of the present disclosure, the outer surface of the application member is covered with an application element, which in this case is a flocking fiber. In brief, the flocking fibers, which can be any commonly used material such as nylon, polyester or any natural fibers, are applied to the surface to be flocked with an adhesive such as an epoxy. The flocking finish to the outer surface of the application member can be achieved by appropriately selected known techniques such as electrostatic flocking.

When using the cosmetic package, the user first removes the cap from the receptacle. To apply cosmetic products to a keratin matrix such as skin, lips, eyelids, cheeks, nails, or any other part of the body, the cosmetic applicator may be applied by the applicator head after being immersed in the cosmetic in the receptacle.

When the cosmetic applicator is withdrawn from the state immersed in the cosmetic, the cosmetic is picked up and held on the entire surface of the wing and the support.

The widest portion of the application member has a greater width than the widest portion of the wiper orifice. Accordingly, when the cosmetic applicator is withdrawn from the receptacle, the widest portion of the application member is caught in the wiper orifice of the wiper. In this embodiment, since the wing is made of an elastically deformable material, it is deformed at the widest portion caught by the wiper orifice so as to pass through the wiper orifice. A free lateral edge substantially opposite the engagement edge of the wing coupling the wing to the support is deformed to curl inwardly towards the concave front surface of the wing on which most of the cosmetic product is retained. Because the wings are curled, the cosmetic remains inside the longitudinal recesses of the wings while the wings are in a deformed state. On the other hand, the convex rear surface of the wing and the first surface of the support are further wiped by the wiper, and act as a blending surface for easy application of cosmetics applied by the concave front surface of the wing.

According to one embodiment, the wiper is made of an elastically deformable material, so that both the wing and the wiper orifice are deformed to reduce resistance to withdrawal and insertion, further improving ease of use.

After the wing has passed through the wiper orifice, it is restored to its original shape with no force applied by the wiper orifice. Thus, as the original shape is restored, the cosmetic is spread over the entire area of the concave front surface of the wing. As a result, the wing can apply the cosmetic uniformly to the lips or any other part of the body. At this time, almost no cosmetics remain on the convex rear surface of the wing, so that the user can safely and quickly apply the cosmetics without worrying about unintentional application other than the target site.

The wiper wipes off excess cosmetics attached to the wing as well as cosmetics attached to the stem.

According to an embodiment of the present disclosure, at least part and preferably all of the applicator head may be manufactured by molding, for example by injection molding. The applicator head may be made of a thermoplastic material; elastomer; thermoplastic elastomers; HYTREL®, for example thermoplastic elastomeric polyesters such as nitrile rubber; silicone rubber; ethylene-propylene terpolymer rubber (EPDM); styrene-ethylene-butylene-styrene (SEBS); styrene-isoprene-styrene (SIS); polyurethane (PU); ethyl vinyl acetate (EVA); polyvinyl chloride (PVC); polyethylene (PE); polyethylene terephthalate (PET); It can be formed by materials known to those skilled in the art to be suitable for injection molding, including polypropylene (PP) and the like.

According to another embodiment, the cross-section of the stem is oval, oval or polygonal, for example square, triangular or rectangular. The stem may be solid as shown, or in a variant it may be hollow.

According to another aspect of the present disclosure, if the stem does not have a circular cross-section, the cap may be fastened to the receptacle by snap-fastening or by some other means without rotation relative to the receptacle. Thus, the wiper can provide a non-circular wiper orifice that is complementary to the cross-section of the stem.

According to one embodiment, the receptacle and cap may be made of a rigid material such as glass, metal, rigid plastic, or any other material known in the art. In an alternative embodiment, the receptacle and cap are made of a flexible material, such as a flexible polymer material or any other material known in the art.

According to one embodiment of the present disclosure, the applicator head may be at least partially made of a material that is more flexible than the material from which the stem is made. According to one embodiment, the receptacle and cap may be made of a rigid material such as glass, metal, rigid plastic, or any other material known in the art. In an alternative embodiment, the receptacle and cap are made of a flexible material, such as a flexible polymer material or any other material known in the art.

According to a preferred embodiment, the application member is elongated along the central longitudinal axis of the applicator head. The application member has a longitudinal axis aligned with the longitudinal axis of the stem. The application member is elongate, ie its extent in a direction parallel to the longitudinal axis is greater than its maximum extension perpendicular to the longitudinal axis. In particular, the maximum extension of the application member in a direction parallel to the longitudinal axis is greater than the maximum extension of the application member in a direction perpendicular to the longitudinal axis of the cosmetic applicator by at least 1.5 times, more preferably by at least 2 times.

According to one embodiment of the present disclosure, the applicator head 10 and the stem are fitted together by a snap fitment. In an alternative embodiment, the applicator head and stem are fitted together by friction fit, gluing, crimping, self-engaging, and the like. According to one embodiment of the present disclosure, the stem has a straight longitudinal axis. In an alternative embodiment, the stem is curved.

The coating body has a curve in the abscissa axis, that is, the coating body has a concave inner surface and a convex outer surface opposite to the inner surface. Accordingly, by the abscissa curve, it is meant that the coated body is curved in the transverse axis perpendicular to the longitudinal axis of the coated body (that is, it is curved from left to right).

The applicator head is configured to load the product to be applied. The distal end of the stem includes an internal longitudinal cavity for receiving and retaining the applicator head. More specifically, the proximal portion of the applicator head is formed as a cylindrical shank configured to be received within the longitudinal cavity of the stem. The molded applicator head may be fixed to the stem by physical fitting, in particular by snapping, gluing, welding or crimping, and the shank of the applicator head may be fixed to the longitudinal cavity of the stem provided at the end of the stem. there is.

According to an embodiment of the present disclosure, the applicator comprises at least three vertical sidewalls: a first sidewall, a second sidewall and a third sidewall; The three sidewalls together form a longitudinal U-shaped cavity configured to receive a cosmetic product therebetween. The U-shaped cavity extends from the proximal to the distal end of the applicator and is open at both the proximal and distal ends of the applicator. The product accumulates in the U-shaped cavity so that the cosmetic applicator can be used for at least a sufficient period of time so that the product, such as a cosmetic or care product, can be sufficiently applied. The first and second sidewalls form lateral sides of the U-shaped cavity and the third sidewall forms the base of the U-shaped cavity. The U-shaped cavity has a longitudinal opening opposite the third sidewall.

According to one embodiment of the present disclosure, the first and second sidewalls are two substantially parallel sidewalls of equivalent length and horizontally aligned sidewalls. The first and second sidewalls are substantially parallel and horizontally spaced apart to form a U-shaped cavity with the third sidewall. The first and second sidewalls extend substantially orthogonally/perpendicularly from the third sidewall.

According to an embodiment of the present disclosure, the first and second sidewalls are configured to bend to change the angle at a non-perpendicular angle with respect to the third sidewall under the influence of an external force.

According to a further embodiment, the first and second sidewalls act like two flexible flaps extending transversely from the third sidewall along substantially the entire length of the applicator. In use, at least one of the flexible flaps flexes inwardly toward the third sidewall during application to release the cosmetic product from the opening of the U-shaped cavity.

According to one embodiment of this embodiment, the first and second sidewalls are configured to fold against the third sidewall between the collapsed state and the rest state. In the resting state, the first and second sidewalls extend in a substantially parallel direction and orthogonal/perpendicular from the third connecting sidewall. In the crushed state, the first and second sidewalls are bent to crush inwardly toward the third sidewall and change their angle with respect to the third sidewall to a non-perpendicular angle.

In accordance with the present disclosure, the thickness, material and/or connection of the first and second sidewalls and the third sidewall is selected such that the first and second sidewalls are bent/rotated relative to the third sidewall. More specifically, the first and second sidewalls are folded inward toward the inner surface of the third sidewall so that the first and second sidewalls abut each other and form a partially crushed folded structure. More specifically, when the applicator is under the influence of an external force applied to the applicator by the wiper and/or the neck of the container, the first and second sidewalls are bent/rotated inward toward the inner surface of the third sidewall to partially to form a collapsed folded structure, and the first and second sidewalls are in contact with each other in the crushed state. When the applicator is pulled back as intended by the wiper or container neck or pushed back into the container in the reverse direction, an external force is applied to the applicator by the wiper and/or the neck of the container. Further, when the force on the applicator is removed, the first and second sidewalls return to their original state in which the first and second sidewalls are substantially perpendicular to the third sidewall.

According to another embodiment, the longitudinal U-shaped cavity of the applicator serves to hold the cosmetic product which can be loaded, transported and applied after wiping of the applicator head.

In an exemplary embodiment, each of the first and second sidewalls has a generally uniform thickness and a substantially flat vertical outer and inner surface. The third sidewall has a thickness greater than the thickness of the first and second sidewalls. Further, the outer surface and the inner surface of the third side wall are curved surfaces. An outer surface of each of the first and second sidewalls together with an outer surface of the third sidewall forms a curved and smooth corner. Accordingly, the corner thickness is substantially greater than the uniform thickness of the first and second sidewalls.

According to a further embodiment of the present disclosure, the first and second sidewalls are integral with the third sidewall.

According to a further embodiment of the present disclosure, the distance between the opposite inner surfaces of the first and second sidewalls defines a span that is significantly less than the length of the first and second sidewalls or the third sidewall. In a preferred embodiment, the span is at least 2 times smaller than the length of the applicator, more preferably at least 3 times smaller than the length of the applicator, and even more preferably at least 5 times smaller than the length of the applicator.

The term "substantially perpendicular" includes the meaning of a slight change from a particular direction. More specifically, the term "substantially vertical" means a vertical state with a deviation of less than 10 degrees.

The term "substantially parallel" includes the meaning of a slight change from a parallel direction. In other words, it means that the two objects or axes are at least 5 degrees or 10 degrees (5 degrees or 10 degrees parallel) within parallelism and extend parallel to each other.

The term “proximal” refers to the side facing the rear cap or shank of the applicator head, while the term “distal” refers to the correspondingly distal side.

According to one aspect of the present disclosure, the applicator head may not be flocked.

According to another embodiment of the present disclosure, the applicator of the applicator head may have an application element on at least one of the three sidewalls or at least a portion of the inner surface or the outer surface. The application element may be selected from the group of tines, flocking, textured surfaces, and the like.

According to a preferred embodiment, the application element is flocked. Flocking can be implemented on a part of the coating body mechanically, electrostatically or by a combination of both techniques.

According to another aspect of this embodiment, each of the first and second sidewalls has a maximum width that is greater than a maximum width of the third sidewall.

According to another embodiment, each of the first and second sidewalls has a variable width along the longitudinal axis of the applicator. More specifically, the widths of the first and second sidewalls first increase from the distal end to a first portion of the length of the applicator, and then decrease to a second portion of the length of the applicator, and then decrease to a third portion of the length of the applicator. increases again. a length of the second portion is greater than a length of the first portion and a length of the third portion; The length of the first portion is longer than the length of the third portion.

Further, each free edge of the first and second sidewalls includes a convex curve extending at the distal portion, the convex curve being followed by a straight edge at the middle portion; The straight edge is followed by a concave curve near the proximal ends of the first and second sidewalls, respectively.

According to one aspect of the present disclosure, the application body may not be flocked.

In another embodiment, the applicator head may have an applicator element. In a preferred embodiment, the application element is flocked, but in a variant embodiment, the application element comprises projections, bristles, tines, suitable for combing and/or loading, transporting and applying cosmetic products such as, for example, mascara, eyeshadow, etc. particles, ribs, grooves, disks, slits, cuts, holes, dimples, foams or other surface features or surface treatments (eg, abrasive).

In a variant embodiment, the applicator may have a substantially C-shaped cross-section and a C-shaped longitudinal cavity.

According to an embodiment of the present disclosure, the applicator may be made from a material selected from the group consisting of elastic or deformable plastic, rubber, sintered or porous material, and/or combinations thereof. An applicator head according to the present disclosure can be manufactured in a single injection molding step. The first and second sidewalls should be thin enough so that the first and second sidewalls can bend and wrap the spring effect even if no soft elastic plastic is used.

According to a fourth embodiment of the present disclosure, the application member of the applicator head includes a cylindrical root portion forming a base of the application member and a circular wing extending from the cylindrical root portion. The circular wing is constituted by a circular plate-like structure curved in a plane perpendicular to the longitudinal axis of the application member. The cylindrical root gradually decreases in thickness and width from the proximal end of the applicator member to the proximal end of the circular wing. The circular wing forms the distal end of the application member.

Further, the circular wings of the application member form at least two main application surfaces opposed to each other, namely a first application surface and a second application surface opposite to the first application surface. At least one of the first application surface and the second application surface is concave, and more specifically, the first application surface has a concave outer surface and the second application surface has a convex exterior surface.

According to another embodiment of the present disclosure, the root portion includes two extensions: a first extension extending longitudinally in opposite directions at each of the first and second application surfaces of the circular wing along the longitudinal axis of the application member; It has a second extension. Each of the first and second extensions extends along the longitudinal direction from the root portion of the application member to at least half the length of each of the first and second application surfaces of the circular wing.

According to an embodiment of the present disclosure, the first and second extensions are similar to the protrusions on each of the first and second application surfaces. The first and second extensions define a rigid region on the application member that provides bending resistance during application. The circular wings without the first and second extensions form a flexible area flexible enough to be bent and adjusted according to the contour of the application surface, allowing for uniform and smooth application of the product during application.

According to one embodiment of the present disclosure, the first and second extensions of the root portion are identical in shape and dimension and extend parallel to each other over their entire length.

In an alternative embodiment, the first and second extensions of the root portion are not identical in shape and dimensions, and may or may not extend in parallel directions. For example, in the second embodiment of the applicator head according to the present disclosure, the first and second extensions of the root portion have unequal shapes and have different lengths along the longitudinal direction of the application member.

According to a further embodiment of the present disclosure, the length of each of the first and second extensions of the root portion is at least about 40% of the total length of the circular wing and less than 95% of the length of the circular wing.

Preferably, the total length of each of the first and second extensions of the root is greater than its width, for example several times longer than its width, ie 2, 3, 4, 5 or 6 times greater than its width. .

The first and second extensions may have any geometrical cross-section, for example may be round or may have a rectangular, triangular, square or irregular cross-section.

The circular wings are flexible enough to flex upon application along the contours of a person's facial skin or lips to provide a uniform coating of cosmetic products. The application member picks up a large amount of cosmetics from the concave outer surface of the first application surface.

According to an embodiment of the present disclosure, the outer surface of the application member is covered with an application element, which in this case is a flocking fiber. In brief, the flocking fibers, which can be any commonly used material such as nylon, polyester or any natural fibers, are applied to the surface to be flocked with an adhesive such as an epoxy. The flocking finish to the outer surface of the application member can be achieved by appropriately selected known techniques such as electrostatic flocking.

According to one aspect of the present disclosure, the application member may be flocked over substantially its entire visible surface. In a variant, at least one of the first and second extensions of the application member may be flocked. In another variation, only the circular wings used to apply the composition may be flocked.

According to one embodiment of the present disclosure, the circular wing may have a smooth or rough surface before being flocked. Preferably, at least one of the first application surface and the second application surface has a textured surface. According to a variant embodiment of the present disclosure, the circular wing has a massage texture on the convex surface of the second application surface for skin irritation and improved absorption of the cosmetic, while the first application surface has a concave surface for smooth application of the cosmetic. Preferably, the massage texture comprises a faceted surface.

According to another embodiment of the present disclosure, there is provided a cosmetic package comprising a cosmetic applicator and a receptacle for holding a product. The cap of the cosmetic applicator has a thread formed in the neck of the receptacle that can be threaded into the thread. Additionally, the distal end of the stem may include an internal longitudinal cavity for receiving and retaining the applicator head.

A wiper may be inserted into the neck of the receptacle to wipe off excess cosmetic product from the cosmetic applicator. The wiper also includes a wiping orifice.

According to one embodiment of the present disclosure, the shank portion fixedly inserted to the stem is integrally molded with the circular wing. According to another embodiment of the present disclosure, when the cosmetic applicator is withdrawn from the state immersed in the cosmetic, the cosmetic is picked up and held on the entire surface of the circular wing due to flocking. The widest portion of the circular wing has a greater width than the widest portion of the wiper orifice. Thus, when the cosmetic applicator is withdrawn from the receptacle, the widest portion of the circular wing is caught in the wiper orifice of the wiper. In this embodiment, since the circular wing is made of an elastically deformable material, it is deformed at the widest portion caught by the wiper orifice so as to pass through the wiper orifice. Since the first application surface of the circular wing on which most cosmetics are held has a concave outer surface, the circular wing is curled into a substantially C-shape. Because the circular wings are curled into a substantially C-shape, the cosmetic remains inside the C-shape while the circular wings are in a deformed state. On the other hand, the second application surface has a convex outer surface and is wiped with a wiper. The second application surface is further wiped and acts as a blending surface for easy application of the cosmetic applied by the first application surface of the circular wing.

According to an embodiment of the present disclosure, the wiper is made of an elastically deformable material, so that both the circular wing and the wiper orifice are deformed to reduce resistance to withdrawal and insertion, further improving the usability.

After the circular wing passes through the wiper orifice, it is restored to its original shape without any force applied by the wiper orifice. Accordingly, as the original shape is restored, the cosmetic is spread over the entire area of the first application surface of the circular wing. As a result, the circular wing can apply cosmetics uniformly to the lips or any other part of the body. At this time, almost no cosmetics remain on the second application surface of the circular wing, so that the user can safely and quickly apply the cosmetics without worrying about unintended application other than the target site.

The wiper wipes off excess cosmetics attached to the circular wing as well as cosmetics attached to the stem.

According to one embodiment, the container and cap may be made of a rigid material such as glass, metal, rigid plastic or any other material known in the art. However, in alternative embodiments, the container and cap may be made of a flexible material, such as a flexible polymeric material or any other material known in the art.

According to an embodiment of the present disclosure, the stem exhibits a circular cross-section, but other shapes do not depart from the scope of the present disclosure. According to another embodiment, the cross-section of the stem is oval, oval or polygonal, for example square, triangular or rectangular. The stem may be solid as shown, or in a variant it may be hollow.

If the stem does not have a circular cross-section, the cap may be fastened to the receptacle by snap-fastening or by some other means without rotating relative to the receptacle. Thus, the wiper can provide a non-circular wiper orifice of section complementary to the cross-section of the stem.

According to one embodiment of the present disclosure, the applicator head may be at least partially made of a material that is more flexible than the material from which the stem is made. According to one embodiment, the receptacle and cap may be made of a rigid material such as glass, metal, rigid plastic, or any other material known in the art. In an alternative embodiment, the receptacle and cap are made of a flexible material, such as a flexible polymer material or any other material known in the art.

According to one embodiment of the present disclosure, the applicator head and stem are fitted together by a snap fitment. However, in alternative embodiments, the applicator head and stem may be fitted together by friction fit, gluing, crimping, self-engaging, and the like.

According to one embodiment of the present disclosure, the stem may have a straight longitudinal axis (Y) as shown. In an alternative embodiment, the stem is curved.

According to a fifth embodiment of the present disclosure, a cosmetic applicator is disclosed comprising a container comprising a chamber for holding a quantity of cosmetic suitable for multiple applications to skin or other keratinous surfaces. The pump mechanism is connected to the vessel and in fluid communication with the chamber. An applicator head comprising an applicator member is connected to the pump mechanism. When the pump mechanism is actuated, an amount of product is delivered from the chamber to the application member.

According to one embodiment, the application member includes a root portion forming a base of the application member. The one or more root extensions extend distally from the root. The circular wing extends from and is supported by the root extension. The circular wing is constituted by a circular plate-like structure that can be curved about the longitudinal axis of the application member. The root extension gradually decreases in thickness and width from the proximal end of the application member toward the proximal end of the circular wing. The circular wing forms the distal end of the application member.

Further, the circular wings of the application member form at least two main application surfaces opposed to each other, namely, a first application surface or first surface and a second application surface or second surface opposite to the first application surface. At least one of the first application surface and the second application surface is concave, and more specifically, the first application surface has a concave surface and the second application surface has a convex outer surface.

According to another embodiment of the present disclosure, the root portion has two root extensions. The two extensions extend at least partially along the longitudinal axis of the application member across the first and second application surfaces of the circular wing. Each of the first and second root extensions extends along the longitudinal direction from the root portion of the application member to at least half the length of each of the first and second application surfaces of the circular wing.

According to one embodiment, the root extension forms a relatively rigid area on the application member that provides bending resistance to the wing during application. The circular wings form a flexible area that is flexible enough to bend and adjust according to the contours of the application surface, allowing for uniform and smooth application of the product during application.

The circular wings are flexible enough to flex upon application along the contours of a person's facial skin or lips to provide a uniform coating of cosmetic products. The application member holds a large amount of cosmetics on the concave outer surface of the first application surface.

At least one of the root extensions includes an internal passageway having an opening in fluid communication with the pump mechanism and one or more outlets. The outlet is positioned to deliver product to the surface of the circular wing. When the pump mechanism is actuated, a selected amount of product flows through the internal passageway to the first application surface of the circular wing.

According to a variant embodiment of the present disclosure, the circular wing has a massage texture on the convex surface of the second application surface for skin irritation and improved absorption of the cosmetic, while the first application surface has a concave surface for smooth application of the cosmetic. Preferably, the massage texture comprises a faceted surface. According to a further embodiment, the textured surface comprises a bath relief surface. The bath relief surface includes an angled embossing pattern, includes a radially facing ridge, and/or includes a recognizable shape including the shape of a sliced citrus surface.

According to another embodiment of the present disclosure, there is provided a cosmetic applicator comprising a container for holding a quantity of cosmetics, a pump mechanism, and an applicator head, as described in the previous embodiment. A container is provided at the proximal end of the cosmetic applicator. A pump mechanism is provided distal to the container. An applicator head is provided at the distal end of the pump mechanism.

Cosmetics, care or pharmaceutical products include viscous cosmetics, mascara, eyebrow powder, lip gloss, hair color, cheek blush, skin care, under-eye cosmetics, pharmaceuticals and similar products.

As shown in FIG. 1 , the cosmetic package 1 has an elongate cylindrical configuration. However, in an alternative embodiment, the cosmetic package 1 has an elongated square, polygonal configuration, oval, triangular, heart-shaped, or any other configuration known in the art.

According to one embodiment, the cosmetic applicator 100 includes an applicator head 10 , a stem 20 , and a closure 30 . The closure 30 of the cosmetic package 1 has a thread 32 on its inner surface, which can be screwed to a thread 202 , formed on the outer surface of the neck 204 of the receptacle 200 . However, in alternative embodiments, the closure 30 snaps into place on the neck 204 of the receptacle 200 , or any other type of mechanism is used to conform the closure 30 to the receptacle 200 . can be used

A wiper 206 for wiping off excess cosmetics from the cosmetic applicator 100 is inserted into the neck 204 of the receptacle 200 . The wiper 206 also includes an annular bead 208 on its outer surface for engaging a corresponding annular groove 210 formed in the inner surface of the neck 204 of the receptacle 200 . The wiper 206 also includes a wiping orifice 215 .

According to one embodiment, the receptacle 200 and the closure 30 may be made of a rigid material such as glass, metal, rigid plastic, or any other material known in the art. However, in alternative embodiments, receptacle 200 and closure 30 are made of a flexible material, such as a flexible polymeric material or any other material known in the art.

According to one embodiment of the present disclosure, the applicator head 10 and the stem 20 are fitted together by a snap fitment. However, in alternative embodiments, the applicator head 10 and stem 20 may be fitted together by friction fit, gluing, crimping, self-engaging, or the like. According to one embodiment of the present disclosure, the stem 20 may have a straight longitudinal axis (X-X) as shown. However, in an alternative embodiment, the stem is curved.

According to one embodiment of the present disclosure, the stem 20 exhibits a circular cross-section. According to another embodiment, the cross-section of the stem 20 is oval, oval or polygonal, for example square, triangular or rectangular. The stem 20 may be solid as shown, or in a variant it may be hollow.

If the stem 20 does not have a circular cross-section, the closure 30 may be fastened to the receptacle 200 by snap-fastening or by some other means without rotating relative to the receptacle 200 . Thus, the wiper 206 may provide a non-circular wiper orifice 215 of a section complementary to the cross-section of the stem 20 .

According to one embodiment of the present disclosure, the applicator head 10 may be made at least in part from a material that is more flexible than the material from which the stem 20 is made.

According to an embodiment of the present disclosure, at least a portion and preferably all of the applicator head 10 may be manufactured by molding, for example by injection molding. thermoplastic materials; elastomer; thermoplastic elastomers; HYTREL®, for example thermoplastic elastomeric polyesters such as nitrile rubber; silicone rubber; ethylene-propylene terpolymer rubber (EPDM); styrene-ethylene-butylene-styrene (SEBS); styrene-isoprene-styrene (SIS); polyurethane (PU); ethyl vinyl acetate (EVA); polyvinyl chloride (PVC); polyethylene (PE); polyethylene terephthalate (PET); Although formed from materials known to those skilled in the art to be suitable for injection molding, including polypropylene (PP), this list is not limiting.

As shown in FIG. 2 , the applicator head 10 includes an application member 40 and a shank portion 60 . The shank portion 60 is held at the distal end 21 of the stem 20 for applying cosmetic products; A closure 30 is retained at the proximal end 23 of the stem 20 . The distal end 21 of the stem 20 includes an inner longitudinal cavity 22 (see FIG. 1 ) for receiving and holding the applicator head 10 .

According to one embodiment, the application member 40 is preferably formed of Desmopan® 487. Desmopan® 487 is a thermoplastic polyurethane. In alternative embodiments, the application member 40 may be formed from any suitable polymeric material or any other material known in the art.

According to an embodiment of the present disclosure, the outer surface of the application member 40 is covered with an application element, which in this case is a flocking fiber (see FIG. 7 ). In brief, the flocking fibers, which can be any commonly used material such as nylon, polyester or any natural fibers, are applied to the surface to be flocked with an adhesive such as an epoxy. The flocking finish to the outer surface of the application member 40 can be achieved by appropriately selected known techniques such as electrostatic flocking.

The outer surface of the application member 40 before being flocked is smooth over its entire surface. That is, the outer surface of the application member 40 before being flocked does not have a surface texture such as a wrinkle finish or a matte finish over its entire surface. In other words, the outer surface of the application member 40 before flocking is smooth and slippery.

Preferably, the flocking process takes place in an electrostatic field, which results in proper orientation of the fibers. The flock on the outer surface of the application member 40 provides a layer capable of holding a small amount of cosmetics suitable for one or two applications. In an alternative embodiment, the exterior of the application member 40 may include injection molded fibers, protrusions, or grooves capable of holding the cosmetic product.

According to an embodiment of the present disclosure, the outer surface of the application member 40 is covered by a flock coating. However, in an alternative embodiment, the outer surface of the application member 40 may not be covered by the flock coating.

As shown in FIG. 3 , the application member 40 further includes a root portion 65 and a spatula 80 . The spatula 80 extends from the root portion 65 . The root portion 65 has a cylindrical shape. However, according to an alternative embodiment, the root portion 65 may be circular or any other shape known in the art.

The spatula 80 has an elongate support 15 extending along the longitudinal axis X-X of the cosmetic applicator 100 (see FIG. 1 ). The spatula 80 includes at least two application surfaces, that is, a first application surface 42 and a second application surface 44 . The first application surface 42 has a concave inner surface 46 while the second application surface 44 has a convex outer surface 47 (see FIG. 5A ). The concave inner surface 46 creates a capacity reservoir. This capacity reservoir serves as a reservoir for cosmetics. A significant amount of cosmetic product may be contained in such a dose reservoir which may be applied to the skin or keratin matrix of a user.

5A and 5B, the second application surface 44 has a convex outer surface 47 that acts as a large blending surface for easy application of cosmetics.

As shown in FIG. 3 , the spatula 80 has two free edges, a first longitudinal edge 51 and a second longitudinal edge 53 . The first longitudinal edge 51 and the second longitudinal edge 53 of the spatula 80 are asymmetric with respect to each other and are each curved. The first longitudinal edge 51 extends in all three-dimensional space. As shown in FIG. 5A , the first longitudinal edge 51 comprises a first curve 52 convex outwardly and a second curve 54 concave outwardly. Viewed from the proximal end 41 to the distal end 43 of the spatula 80 , the first curve 52 is followed by a second curve 54 on the first longitudinal edge 51 .

The first and second curves differ from each other by the property of the curve or by the radius of curvature. According to the present disclosure, if the curve does not correspond to an arc, "the radius of curvature is measured at the vertex of the curve". A first curve 52 is created about a first axis of curvature with respect to a first radius of curvature. A second curve 54 is created about a second axis of curvature for a second radius of curvature. The first axis of curvature and the second axis of curvature are not parallel and extend in different directions. The first radius of curvature may or may not be the same as the second radius of curvature. More specifically, the first radius of curvature is greater than the second radius of curvature such that the first curve 52 extends to at least 75% of the length of the first longitudinal edge 51 .

As shown in FIG. 5B , the second longitudinal edge 53 also extends in both three-dimensional space. The second longitudinal edge 53 comprises a third curve 55 convex outwardly, a fourth curve 57 concave outwardly, and a fifth curve 59 outwardly convex.

The third, fourth and fifth curves 55 , 57 , 59 differ from each other by the property of the curve or by the radius of curvature. A third curve 55 is created about a third axis of curvature for a third radius of curvature. A fourth curve 57 is created about a fourth axis of curvature for a fourth radius of curvature. A fifth curve 59 is created about a fifth axis of curvature for a fifth radius of curvature.

The third, fourth, and fifth axes of curvature are not parallel and extend in different directions. The third, fourth, and fifth radii of curvature may or may not be the same. In particular, the third radius of curvature and the fourth radius of curvature may or may not be the same. 5B , the fourth radius of curvature is greater than the third radius of curvature. The fifth radius of curvature is smaller than the fourth and fifth radii of curvature. More specifically, at least one of the third curve 55 or the fourth curve 57 extends to at least 30% of the length of the second longitudinal edge 53 . The fifth curve 59 extends to at least 10% of the length of the second longitudinal edge 53 .

Viewed from the proximal end 41 to the distal end 43 of the spatula 80 , the third curve 55 is followed by a fourth curve 57 , further comprising a third curve on the second longitudinal edge 53 . 5 curve 59 follows.

As shown in FIG. 3 , the first application surface 42 is substantially defined by a first longitudinal edge 51 and a second longitudinal edge 53 , except for the proximal end 41 of the spatula 80 . It has an enclosed recess 45 . A gap 70 exists between the first longitudinal edge 51 and the second longitudinal edge 53 near the proximal end 41 of the spatula 80 . The recess 45 serves to hold the cosmetic product.

When the cosmetic applicator 100 is applied to the keratin substrate, the cosmetic present in the recess 45 may be deposited and the surface of the cosmetic product in contact with the lips or any other part of the body may be relatively large, thus The lips or any other part of the body can be masked relatively quickly.

The recess 45 extends longitudinally from the proximal end 41 to the distal end 43 of the spatula 80 . Further, the recess 45 extends along a longitudinal axis that does not coincide with the longitudinal axis X-X of the cosmetic applicator 100 (see FIG. 1 ). More specifically, the recess 45 is off-center with respect to the longitudinal axis X-X of the cosmetic applicator 100 and forms a non-zero angle with the longitudinal axis X-X of the cosmetic applicator 100 . Recess 45 opens outward over the entire length of spatula 80 through first application surface 42 for use in applying product.

According to a preferred embodiment, the recess 45 extends more than half the width of the spatula 80 . However, according to an alternative embodiment, the recess 45 may not extend more than half the width of the spatula 80 . The width of the recess 45 passes through the extreme between the proximal end 41 and the distal end 43 of the spatula 80 . For example, the extreme is the maximum. More specifically, when viewed from the front, the recess has the widest portion that gradually decreases in width from the widest portion to the proximal end 41 or the distal end 43 of the spatula 80 .

According to a preferred embodiment, the recess 45 may cross more than half the length of the spatula 80 . However, according to an alternative embodiment, the recess 45 may not cross more than half the length of the spatula 80 .

The first longitudinal edge 51 and the second longitudinal edge 53 converge to form a narrow tip 50 at the distal end 43 of the spatula 80 . The narrow tip 50 assists in the accurate deposition of the cosmetic when applying it to the user's skin or keratin matrix.

Also, according to one embodiment, the narrow tip 50 does not coincide with the longitudinal axis X-X of the cosmetic applicator 100 (see FIG. 1 ). More specifically, the narrow tip 50 is off-center with respect to the longitudinal axis X-X of the cosmetic applicator 100 .

When using the cosmetic package 1 , the user first separates the closure 30 from the receptacle 200 . To apply cosmetic products to a keratin matrix such as the skin, lips, eyelids, cheeks, nails, or any other part of the body, the cosmetic applicator 100 is immersed in the cosmetic in the receptacle 200 followed by the applicator head 10 ) can be applied by When the cosmetic applicator 100 is withdrawn from the state immersed in the cosmetics (the state shown in FIG. 1 ), the cosmetics are picked up and held on the entire surface of the spatula 80 .

As shown in FIG. 1 , the widest portion of the spatula 80 has a greater width than the widest portion of the wiper orifice 215 . Accordingly, when the cosmetic applicator 100 shown in FIG. 1 is withdrawn from the receptacle 200 , the widest part of the spatula 80 is caught in the wiper orifice 215 of the wiper 206 . In this embodiment, since the spatula 80 is made of an elastically deformable material, it is deformed at the widest portion caught by the wiper orifice 215 so as to pass through the wiper orifice 215 .

Since the first application surface 42 of the spatula 80 on which most of the cosmetics are held has a concave inner surface 46, the spatula 80 has a first longitudinal edge 51 and The second longitudinal edges 53 are curled into a substantially C-shape approaching one another. Because the spatula 80 is curled into a substantially C-shape, the cosmetic remains inside the C-shape while the spatula 80 is in a deformed state. On the other hand, the second application surface 44 has a convex outer surface 47 and is wiped with the wiper 206 . The second application surface 44 acts as a blending surface for easy application of the cosmetic which is taken off and applied by the first application surface 42 of the spatula 80 .

The wiper 206 is made of an elastically deformable material, and both the spatula 80 and the wiper orifice 215 are deformed to reduce resistance to withdrawal and insertion, thereby further improving ease of use.

After the spatula 80 has passed through the wiper orifice 215 , it is restored to its original shape as shown in FIG. 6A in a state where no force is applied by the wiper orifice 215 . Accordingly, as the original shape is restored, the cosmetic is spread over the entire area of the first application surface 42 of the spatula 80 . As a result, the spatula 80 can uniformly apply the cosmetics to the lips or any other part of the body. At this time, since cosmetics hardly remain on the second application surface 44 of the spatula 80, the user can safely and quickly apply the cosmetics without worrying about unintentional application other than the target site.

The wiper 206 serves to wipe off the excess cosmetics attached to the spatula 80 as well as the cosmetics attached to the stem 20 .

The shank member 7 is configured to be received and retained within the longitudinal cavity 22 of the stem 20 (see FIG. 8 ).

The application member 8 further includes a support 8a and a wing 8b extending from the support 8a. The support 8a extends in the longitudinal axis X direction of the applicator 100 . 11 and 13 , the wing 8b is curved in the transverse axis Y perpendicular to the X axis, that is, the wing 8b is curved from left to right so that the wing 8b has a longitudinal recess 11 . to form The wing 8b has a concave front surface 9a and a convex rear surface 9b opposite to the concave front surface 9a. The convex back 9b provides a large blending surface for smooth and efficient application of cosmetics. Since the application member 8 picks up a large amount of product from the concave front surface 9a of the wing 8b, re-immersion is not required during application.

More specifically, the longitudinal concave portion 11 of the concave front surface 9a of the wing 8b facilitates retention of the cosmetic product. When the cosmetic applicator 100 is applied to the keratin substrate, the cosmetic present in the recess 11 may be deposited and the surface of the cosmetic product in contact with the lips or any other part of the body may be relatively large, thus The lips or any other part of the body can be masked relatively quickly.

According to one aspect of the present disclosure, the longitudinal recess 11 extends along the length of the wing 8b along a longitudinal axis A which does not coincide with the longitudinal axis X of the application member 8/stem 20 . It extends in the longitudinal direction (see FIG. 8). More specifically, the longitudinal recess 11 is off-center with respect to the longitudinal axis X of the application member 8 and forms a non-zero angle with the longitudinal axis X of the application member 8 .

11 , the wing 8b has a first lateral edge 9c and a second lateral edge 9d opposite the first lateral edge 9c. At least a portion of the first lateral edge 9c has an engaging edge engaging the support 8a such that the support 8a laterally supports the wing 8b on both sides 9a, 9b of the wing 8b. 9c). In other words, the support 8a laterally supports the wing 8b. At least a major portion of the support 8a of the application member 8 forms at least a major portion of the proximal portion 11a of the application member 8 .

11-15 , the support 8a has two opposing major surfaces, namely a first front side 6a, an opposing second rear surface 6b, and two opposite sides, namely a third side surface 6c and and a fourth side surface 6d. The third side 6c is convexly curved along the longitudinal axis X and along an axis Z substantially perpendicular to the X and Y axes. Further, the fourth side 6d comprises a convex curve 14a followed by a concave curve 14b when viewed from the proximal portion 11a to the distal portion 11b of the support 8a (see FIG. 12 ).

The wing 8b extends laterally from the fourth side 6d of the support 8a. The engaging edge 9c of the wing 8b is connected along at least part of the convex curved surface and the concave curved surface of the fourth side surface 6d of the support body 8a. In alternative embodiments, the curves of the third and fourth sides 6c, 6d or the shape of the support 8a may be different, so that the present disclosure provides for the curves of the third and fourth sides 6c, 6d or It is not limited by the shape of the support body 8a.

The application member 8 is made of an elastomer, in particular a thermoplastic elastomer.

13-15, the wing 8b is relatively thinner than the support 8a. More specifically, the wing 8b is at least two or three times thinner than the support 8a. For that reason, the wing 8b is in particular more flexible and elastically bendable compared to the support 8a. The wings 8b are flexible enough to bend when applied along the contours of a person's facial skin or lips to provide a uniform coating of cosmetic products.

11, a swirled extension 6e extends from the distal end of the support 8a to the concave front 9a of the wing 8b and provides strength to the wing 8b during application. . However, the swirl-like extension 6e is an optional feature, and the application member 8 may or may not include any such extension.

Further, the width of the wing 8b is first increased from the proximal portion 15 of the wing 8b to form the widest portion W, and then from the widest portion W to the distal end 13 of the wing 8b. gradually decreases to A narrow tip 13 is formed at the distal end 13 of the wing 8b which coincides with the distal end 13 of the application member 8 . Also, the narrow tip 13 at the distal end allows the user to draw precise lines during application. Also, the narrow tip 13 at the distal end 13 of the application member 8 may not coincide with the longitudinal axis X of the application member 8 (see FIG. 11 ). More specifically, the narrow tip 13 is off-center with respect to the longitudinal axis X of the cosmetic applicator 100 .

In addition, the width of the third side surface 6c of the support 8a is, when viewed from the left side view of the application member 8 , from the proximal end 12 of the application member 8 toward the distal portion of the application member 8 . It decreases continuously (see Figs. 12-14). More specifically, the support 8a in the left side view of the application member 8 has a convexly curved shape toward the tip 13 of the application member 8 and has an inclined side edge. The third side 6c of the backing 8a provides a narrow blending surface for aligning and blending cosmetic products, for example in the corners of the lips and eyes.

According to an embodiment of the present disclosure, the outer surface of the application member 8 is covered with an application element 16 , in this case a flocking fiber (see FIG. 17 ). In brief, the flocking fibers, which can be any commonly used material such as nylon, polyester or any natural fibers, are applied to the surface to be flocked with an adhesive such as an epoxy. The flocking finish to the outer surface of the application member 8 can be achieved by appropriately selected known techniques such as electrostatic flocking. According to an embodiment of the present disclosure, at least one of the wing 8b and the support 8a may be flocked. According to an alternative embodiment of the present disclosure, the application member 8 may not be flocked.

When using the cosmetic package 1 , the user first separates the closure 30 from the receptacle 200 .

In another variant, only the circular wings 5 used for applying the composition may be flocked.

According to one aspect of the present disclosure, the circular wing 5 may have a smooth or rough surface before being flocked. Preferably, at least one of the first application surface 5a and the second application surface 5b has a textured surface.

According to a modified embodiment of the present disclosure, as shown in FIGS. 36-38 , the circular wing 5 is massaged on the convex surface 9b of the second application surface 5b for skin irritation and improved absorption of cosmetics. On the other hand, the first application surface 5a has a concave surface for smooth application of cosmetics. The massage texture includes a faceted surface.

When the cosmetic applicator 100 is withdrawn from the state immersed in the cosmetics (the state shown in FIG. 26 ), the cosmetics are picked up and held on the entire surface of the circular wing 5 due to the flocking 16 . 26 , the widest portion of the circular wing 5 has a greater width than the widest portion of the wiper orifice 215 . Accordingly, when the cosmetic applicator 100 shown in FIG. 26 is withdrawn from the receptacle 200, the widest part of the circular wing 5 is caught in the wiper orifice 215 of the wiper 206 (see FIG. 34). Since the circular wing 5 in this embodiment is made of an elastically deformable material, it is deformed at the widest portion caught by the wiper orifice 215 so as to pass through the wiper orifice 215 .

Since the first application surface 5a of the circular wing 5 on which most of the cosmetics are held has a concave outer surface 9a, the circular wing 5 is curled into a substantially C-shape. Since the circular wing 5 is curled into a substantially C-shape, the cosmetic remains inside the C-shape while the circular wing 5 is in a deformed state. On the other hand, the second application surface 5b has a convex outer surface and is wiped with the wiper 206 . The second application surface 5b is further polished and acts as a blending surface for easy application of the cosmetic applied by the first application surface 5a of the circular wing 5 .

After the circular wing 5 has passed through the wiper orifice 215, it is restored to its original shape as shown in FIG. 29 without any force being applied by the wiper orifice 215. Accordingly, as the original shape is restored, the cosmetic is spread over the entire area of the first application surface 5a of the circular wing 5 . As a result, the circular wings 5 can uniformly apply cosmetics to the lips or any other part of the body. At this time, since cosmetics hardly remain on the second application surface 5b of the circular wing 5, the user can safely and quickly apply the cosmetics without worrying about unintentional application other than the target site. The wiper 206 serves to wipe off the excess cosmetics attached to the circular wing 5 as well as the cosmetics attached to the stem 20 .
