DETAILED DESCRIPTION

(22) As shown throughout the drawings, like reference numerals designate like or corresponding parts. While illustrative embodiments of the present disclosure have been described and illustrated above, it should be understood that these are exemplary of the disclosure and are not to be considered as limiting. Additions, deletions, substitutions, and other modifications can be made without departing from the spirit or scope of the present disclosure. Accordingly, the present disclosure is not to be considered limited by the foregoing description.

(23) Throughout this specification, the terms “comprise,” “comprises,” “comprising” and the like, shall consistently mean that a collection of objects is not limited to those objects specifically recited.

(24) FIG. 1 illustrates a longitudinal sectional view of a cosmetic package 1. The cosmetic package 1 comprises a receptacle 200 for holding a product (not shown) and a cosmetic applicator 100. The cosmetic applicator 100 comprises an applicator head 10, a stem 20, and a cap 30, see FIG. 2. The cap 30 of the cosmetic applicator 100 has threads 32 that can be screwed onto threads 202, formed on a neck 204 of the receptacle 200. The applicator head 10 is retained at a distal end of the stem 20 for applying the product; and the cap 30 at a proximal end of the stem 20.

(25) In general, the use of the terms “distal” and “proximal” herein is supposed to mean that the distal is the end facing towards the inside of the storage receptacle 200, whereas the proximal is the end facing towards the removal opening of the receptacle 200.

(26) As seen in FIG. 1, the distal end of the stem 20 includes an interior longitudinal cavity 22 for receiving and retaining the applicator head 10. Inserted in the neck 204 of the receptacle 200 is a wiper 206 for wiping off excess product from the cosmetic applicator 100.

(27) Further, the applicator head 10 of cosmetic applicator 100 may be used to apply the product including a cosmetic or care product. The cosmetic or care product includes viscous cosmetics, mascara, eyebrow powder, lip gloss, hair color, skincare, under-eye cosmetics, pharmaceutical, and like products.

(28) As shown in FIGS. 3-5, the applicator head 10 comprises an applying member 8 at its distal portion and a shank member 7 at its proximal portion. The shank member 7 is configured to be received and retained within the longitudinal cavity 22 of the stem 20 (see FIG. 1).

(29) In the present embodiment, the shank member 7 and the applying member 8 are integral, however in alternate embodiments that may be two separate parts. The applying member 8 is designed to apply the product to a target surface.

(30) The applicator head 10 and the applying member 8 are elongated along a central longitudinal axis X of the cosmetic applicator 100 (refer to FIG. 1). The applying member 8 has a distal end 3 and a proximal end 4 that are opposite relative to the axis X and are separated, along said axis X, by a distance marked L in FIG. 2. Said distance L is, for example, between 12 mm and 20 mm, and preferably between 13 mm, or 16 mm.

(31) The applying member 8 includes a distal end face 6 and at least one sidewall 9 extending from the proximal end 4 of the applying member 8 to a peripheral edge of the distal end face 6. As illustrated in FIG. 4, the at least one sidewall 9 of the applying member 8 includes a proximal portion 9a, a distal portion 9c, and a concave central portion 9b extending between the distal portion 9a and the proximal portion 9c. The proximal portion 9a of the at least one sidewall 9 of the applying member 8 can be substantially spherical or cylindrical. The distal portion 9c of the at least one sidewall 9 of the applying member 8 has a flared oval shape.

(32) Further, the distal end face 6 is an inclined and convex surface. The distal end face 6 has an oval or ellipse shape, as illustrated in FIGS. 3-4. According to an aspect of the present disclosure, the distal end face 6 makes an angle A with the longitudinal axis X. Preferably, the distal end face 6 makes an acute angle A with the longitudinal axis X of the applying member 8. Preferably, this acute angle A is in the range between 30° and 75°, ideally in the range between 50° and 70°.

(33) According to an aspect of the present disclosure, the distal end face 6 is available for use as a free, unhindered surface that can be entirely brought into contact with the part of the skin to be treated for the application of the cosmetic. The distal end face 6 is ideally flocked which is not graphically depicted here. A flocked surface can store significantly more product than a smooth plastic surface. For particular applications, though, it can also be embodied as an unflocked application-ready plastic surface.

(34) The transverse cross-section of the applying member 8 varies along the length direction. The applying member 8 has a non-circular and rounded transverse cross-section along a major portion of its length. More particularly, applying member 8 has non-circular and rounded transverse cross-sections along the distal portion 9c and the concave central portion 9b of the at least one sidewall 9, as illustrated in FIGS. 9 and 10. Each of the transverse cross-sections of the applying member 8 at the distal portion 9c and the concave central portion 9b is rounded and has a major axis C and a minor axis D, and wherein the major axis C and the minor axis D of the various cross-sections vary. The length of the major axis C of the transverse cross-sections increases gradually from a mid-length of the applying member 8 towards the distal end face 6 of the applying member 8. FIG. 9 shows a transverse cross-section of the applying member 8 at the distal portion 9c which is an ellipse in shape. FIG. 10 shows a transverse cross-section of the applying member 8 at the concave central portion 9b which is oval. FIG. 11 shows a transverse cross-section of the applying member 8 at the proximal portion 9a that is substantially circular.

(35) In the exemplary embodiment, the proximal portion 9a of the applying member 8 has rounded cross-sections that are substantially circular. The distal portion 9c, the concave central portion 9b, and the distal end face 6 of the applying member 8 have rounded cross-sections that are oval or elliptical. The applying member 8 is thus not rotationally symmetric, meaning that the applying member 8 is flattened, particularly the distal portion 9c, the concave central portion 9b are flattened.

(36) The at least one sidewall 9 of the applying member 8 includes a convexly curved surface followed by a concavely curved surface when seen along the proximal end 3 to the distal end 4 of the applying member 8, as seen in FIGS. 3-6. The at least one sidewall 9 of the applying member 8 defines at least four curved faces around the longitudinal axis X. The four curved faces of the at least one sidewall 9 include a front side face 11a, a back side face 11b, a left side face 11c, and a right side face 11d. Each of the front side face 11a, the back side face 11b, the left side face 11c, and the right side face 11d includes a convexly curved surface followed by a concavely curved surface when seen along the proximal end 3 to the distal end 4 of the applying member 8. In other words, each of the front side face 11a, the back side face 11b, the left side face 11c and the right side face 11d follow substantially the same curves along the longitudinal axis X (see FIGS. 3-5). The left side face 11c and the right side face 11d are symmetrical relative to a mid-plane comprising the longitudinal axis X, as seen in FIGS. 5 and 6. The distal end face 6 is inclined towards the front side face 11a.

(37) Referring FIGS. 2, and 6, the concavely curved surface of the at least one sidewall 9 of the applying member 8 has an extremum depth M defined on the outer surface at about half a length L of the applying member 8 at the concave central portion 9b. This concavely curved surface has the extremum depth M between the distal 4 and proximal 3 ends and preferably is substantially equidistant from said distal and proximal ends 3, 4. The width of each of the four curved faces 11a, 11b, 11c, and 11d of the at least one sidewall 9 first increases, from the proximal end 4 of the applying member 8, then decreases towards the mid-length of the applying member 8 before increasing gradually towards the distal end 3 of the applying member 8, as seen in FIGS. 3-6.

(38) The convexly curved surface of the at least one sidewall 9 defines a rounded convex surface at the proximal portion 9a of the applying member 8 adjacent to the proximal end 4. The convexly curved surface of the at least one sidewall 9 of the applying member 8 defines an extremum P at substantially about one-fourth of the length L of the applying member 8 at the proximal portion 9a, refer FIG. 6.

(39) The applying member 8 may have a chamfered region between the at least one sidewall 9 and the distal end face 6. The height of this chamfer 27 will be less than 3 mm.

(40) The left side face 11c and the right side face 11d have the same shape as each other or similar shape to each other, as shown in FIGS. 5 and 6. Each of the front side face 11a, the back side face 11b, the left side face 11c, and the right side face 11d has a varying width in the longitudinal direction of the applying member 8, as seen in FIGS. 3-6. An upper half portion of each of the back side face 11b and the front side face 11a is at least 20% narrower than an upper half portion of each of the left side face 11c and the right side face 11d. More particularly, the distal portion 9c and the concave central portion 9b of each of the back side face 11b and the front side face 11a are at least 20% narrower than the distal portion 9c and the concave central portion 9b of each of the left side face 11c and the right side face 11d.

(41) The maximum width W1 of each of the front side face 11a and the back side face 11b is defined at the proximal portion 9a of the applying member 8 on the extremum P of the convexly curved surface about one-fourth of the length L of the applying member 8. The maximum width W2 of each of the left side face 11c and the right-side face 11d is defined at the distal portion 9c of the at least one sidewall 9 that is spaced from the distal end 3 of the applying member 8. The maximum width W1 of each of the front side face 11a and the back side face 11b is slightly less than the maximum width W2 of each of the left side face 9c and the right-side face 9d. The maximum width W1 of each of the front side face 9a and the back side face 9b is between 5-7 mm. The maximum width W2 of each of the left side face 9c and the right-side face 9d is between 5-8 mm.

(42) Referring to FIGS. 7 and 8, the minimum width of each of the four curved faces 11a, 11b, 11c, and 11d are defined at the concave central portion 9b of the at least one sidewall 9. The minimum width W3 of each of the front side face 9a and the back side face 9b is lesser than the minimum width W4 of each of the left side face 9c and the right side face 9d. More particularly, the minimum width W3 of each of the front side face 9a and the back side face 9b is at least 30% less than the minimum width W4 of each of the left side face 9c and the right side face 9d. The minimum width of the front side face 9a and the back side face 9b is preferably between 3-5 mm. The minimum width of the left side face 9c and the right side face 9d is preferably between 5-6 mm.

(43) On the front side face 11a, the width W3 of the applying member 8 at the concave central portion 9b is smaller than the maximum width W1 at the proximal portion 9a and a maximum width W5 of the distal portion 9c on the front side face 11a. Further, the maximum width W3 of the proximal portion W3 on the front side face 11a may be substantially larger or equal to the maximum width W5 of the distal portion 9c of the applying member 8 on the front side face.

(44) Further, the width W1, W6 of the rounded convex surface at the proximal portion 9b of the applying member 8 may be substantially the same on all the four curved faces 11a, 11b, 11c, 11d of the at least one sidewall 9.

(45) The front side face 9a has a height less than the height of the back side face 9b, as seen in FIGS. 2 and 4. The height of the front side face 11a is at least 60% of the height of the back side face 9a, preferably it is about 70% of the height of the back side face 11b. In the exemplary embodiment, the height of the back side face 11b is between 13-16 mm. Furthermore, as seen in FIGS. 4 and 7, the length of the distal portion at the front side face 11a is at least 60% less than the length of the distal portion at the back side face 11b.

(46) The concavely curved surface of the front side face 11a has a first radius of curvature and the concavely curved surface of the back side face 11b has a second radius of curvature and wherein the first radius of curvature is shorter than the second radius of curvature.

(47) Referring to FIG. 12, the distal end face 6 of the applying member 8 has a maximum width B between 5-7 mm and a length L2 preferably between 7-10 mm. The distal end face 6 has a consistently continuous curve, i.e. the distal end face 6 is not flat, but instead protrudes outward in a convex fashion. The embodiment shown in FIGS. 4 and 5 has the distal end face 6 has narrower dimensions than that of the four curved faces, thus also allowing for a more accurate application and contour lining. A surface area of the distal end face is at least 10% smaller than a surface area of the front side face and at least 20% smaller than the surface area of each of the backside face, the left side face, and the right side face.

(48) Referring back to in FIG. 7, the at least one sidewall 9 of the applying member 8 flares outwards towards the distal end thereof. Because of flaring, a distal endpoint N of the front side face 11a is furthest away from the longitudinal axis X on the front side face 11a. Another distal endpoint H on the back side face 11b is furthest away from the longitudinal axis X on the back side face 11b.

(49) Thus, when removing the applying member from the receptacle 200 containing the cosmetic product and through the wiper 204, the amount of cosmetic adhering to the concave central portion 9b substantially remains there. It is applied on the skin by moving the applying member 8 along the skin, its central longitudinal axis X being substantially perpendicular to the longitudinal direction of the skin. The distal end face 6 of the applying member 8 may serve to locally spread the cosmetic, if necessary, or to outline a contour.

(50) The applying member 8 is not rotationally symmetric, as illustrated in particular in FIGS. 9-11, meaning that the applying member 8 is flattened, with this front side face 11a, back side face 11b to be used to precisely apply the cosmetic, while the left and the right side faces 11c, 11d may be used for blending. The applying member 8 is elongated, that is to say, its extent in a direction parallel to the longitudinal axis X is larger than its largest extension perpendicularly to the longitudinal axis X. Particularly, the largest extension of the applying member 8 in the direction parallel to the longitudinal axis X by at least a factor of 1.5, more preferably is greater by at least a factor of 2 than the greatest extension of the applying member 8 in a direction perpendicular to the longitudinal axis X.

(51) According to an embodiment of the present disclosure, an outer surface of the applying member 8 may be covered with an application element 16 which in this case is flocked fibers, see FIG. 13. Briefly, the fibers for flocking which may be of any commonly used material, such as nylon, polyester, or any natural fiber are applied with an adhesive, such as an epoxy, to the surface to be flocked. The flocking finish to the outer surface of the applying member 8 may be achieved by an appropriately chosen known technique, such as electrostatic flocking.

(52) According to an alternate embodiment of the present disclosure, the applying member 8 may or may not be flocked or partially flocked.

(53) In the present example, the applying member 8 is made of a flexible material, in particular plastic material. More particularly, the applying member 8 is made of an elastomer, in particular a thermoplastic elastomer.

(54) FIGS. 14-20 shows applicator head 300 with an applying member 38 according to a second embodiment of the present disclosure. The applying member 38 is different from the applying member 8 of the first embodiment, as the applying member 38 has at least one orifice 37 (see FIG. 15) designed to dispense a cosmetic product. The applicator head 300 is configured to be part of a cosmetic package 2 as shown in FIG. 14 and is mounted on an opening of a receptacle 400. Further, the applicator head 2 comprises an internal product delivery passageway 39 that terminates in at least one orifice 37 on a distal end face 66 of the applying member 38. The at least one orifice 37 is positioned along a central longitudinal axis X1 of the applicator head 300 for dispensing the cosmetic product, refer to FIG. 16.

(55) The applying member 18 also differs from the applying member 8 of the first embodiment in terms of size and dimensions.

(56) Further, as shown in FIG. 17, the distal end face 66 of the applying member 38 makes a non-zero angle A1 with central longitudinal axis X1 of the applicator head 300. This design facilitates the application of the product to the user's skin. In various implementations, the angle A1 may be between about 35° and about 75°. Still, further implementations may have angles anywhere from 5° to 90°.

(57) As shown in FIG. 15, the applying member 38 includes at least one sidewall 40. Referring to FIG. 17, the at least one sidewall 40 of the applying member 38 includes a proximal portion 40a, a distal portion 40c, and a concave central portion 40b extending between the distal portion 40a and the proximal portion 40c. The proximal portion 40a of the at least one sidewall 40 of the applying member 38 can be substantially cylindrical. The distal portion 49c of the at least one sidewall 40 of the applying member 38 has a flared oval shape. The transverse cross-section of the concave central portion 40b is oval or elliptical (not shown).

(58) According to an aspect of the present disclosure, the transverse cross-section of the applying member 38 varies along the length direction. The applying member 38 has non-circular and rounded transverse cross-sections along a major portion of its length. More particularly, the applying member 38 has non-circular and rounded transverse cross-sections along the distal portion 40c and the concave central portion 40b of the at least one sidewall 40.

(59) The applying member 38 is thus not rotationally symmetric, meaning that the applying member 38 is flattened, particularly the distal portion 40c, the concave central portion 40b are flattened.

(60) Referring to FIGS. 16, 17 and 18, the at least one sidewall 40 of the applying member 38 defines at least four curved faces around the longitudinal axis X1. The four curved faces of the at least one sidewall 40 include a front side face 41a, a back side face 41b, a left side face 41c and a right side face 41d. The width of each of the four curved faces 11a, 11b, 11c, 11d of the at least one sidewall 9 decreases from the proximal end 34 of the applying member 38 towards the mid-length of the applying member 38 and then increases gradually towards a distal end 33 of the applying member 38, as seen in FIGS. 16-18.

(61) The left side face 41c and the right side face 41d have the same shape as each other or similar shape to each other, as shown in FIG. 16.

(62) Referring to FIGS. 17-18, the maximum width D1 of each of the front side face 41a, the back side face 41b, the left side face 41c and the right-side face 41d is defined at the proximal portion 40a of the at least one sidewall 40. The maximum width of each of the front side face 41a and the back side face 41b is substantially equal to or less than the maximum width of each of the left side face 41c and the right-side face 41d. The maximum width of each of the front side face 41a, the back side face 41b, the left side face 41c and the right-side face 41d is between 9 mm to 11 mm.

(63) As shown in FIGS. 17 and 18, the minimum width of each of the front side face 41a, the back side face 41b, the left side face 41c, and the right-side face 41d is defined at the concave central portion 40b of the at least one sidewall 40. The minimum width D2 of each of the front side face 41a and the back side face 41b is lesser than the minimum width D3 of each of the left side face 41c and the right side face 41d. More particularly, the minimum width D2 of each of the front side face 41a and the back side face 41b is at least 20% less than the minimum width D3 of each of the left side face 41c and the right side face 41d. The minimum width D2 of each of the front side face 41a and the back side face 41b is preferably between 5-8 mm.

(64) The front side face 41a has a height less than the height of the back side face 41b, as seen in FIG. 17. The height of the front side face 41a is at least 60% of the height of the back side face 41a. In the exemplary embodiment, the height of the back side face 41a is between 15-17 mm.

(65) The distal end face 66 is inclined towards the front side face 41a, as seen in FIGS. 15 and 16.

(66) The front side face 41a has a concavely curved surface with a first radius of curvature and the back side face 41b has another concavely curved surface of the second radius of curvature and wherein the first radius of curvature is shorter than the second radius of curvature, refer FIG. 17.

(67) Further, as seen in FIG. 17, the at least one sidewall 40 of the applying member 38 flares outwards towards the distal end thereof. Because of flaring, a distal endpoint N1 of the front side face 41a is furthest away from the longitudinal axis X1 on the front side face 41a.

(68) FIG. 18 shows a top view of the applicator head 300. As seen in FIG. 18, the distal end face 66 of the applying member 6 has an elliptical shape.

(69) FIG. 20 illustrates a perspective view of the applicator head 300 with an outer surface of the applying member 38 flocked with fibers 46.

(70) FIG. 15 illustrates the construction of the applicator head 300. The applicator head 300 includes a shank member 36 which connects the applying member 38 to the receptacle 400 (see FIG. 14). The shank member 36 of the applicator head 300 may be secured to the receptacle 400 by, for example, a press-fit, snap-fit, adhesive, and/or engagement by one or more engagement features.

(71) Referring to FIG. 14, cosmetic package 2 includes a cap 50 to cover the applicator head 300 and protect it from the external atmosphere. The cap 50 may include a pin that extends from an inner surface of the top of the cap 50 and is inserted in the orifice 37 of the applicator head 38 to seal to the orifice 37.

(72) According to an embodiment of the present disclosure, at least a part and preferably all of the applicator head 10, 300 can be made by molding, e.g. by injection-molding, e.g. in a material selected from the following list: thermoplastic materials; elastomers; thermoplastic elastomers; thermoplastic elastomer polyester such as HYTREL®, for example; 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); polypropylene (PP); this list not being limiting.

(73) In the first embodiment, the wiper 206 serves to wipe off not only the excess cosmetic product attached to the applying member 8 but also the cosmetic product attached to the stem 20.

(74) According to the first embodiment, the receptacles 200, 400 and the caps 30, 50 may be made of a rigid material like glass, metal, hard plastic, or any other material known in the art. However, in alternate embodiments, the receptacles 200, 400 and the cap 30, 50 may be made of a flexible material like flexible polymeric material or any other material known in the art.

(75) According to the first embodiment of the present disclosure, the stem 20 presents a circular cross-section, but it is not beyond the ambit of the present disclosure for this to be otherwise, in particular when the cross-section of the stem 20 is oval, elliptical, or polygonal, e.g. square, triangular or rectangular. The stem 20 can be solid as shown, or, in a variant, it could be hollow.

(76) When the stem 20 is not of circular cross-section, the cap 30 can be fastened on the receptacle 200 by snap-fastening or by some other means, without turning relative to said receptacle 200. The wiper 206 can thus present a non-circular wiper orifice 215 of the section that is complementary to the section of the stem 20.

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

(78) According to the first embodiment of the present disclosure, the applicator head 10 and the stem 20 are fitted together by a snap fitment. However, in alternate embodiments, the applicator head 10 and the stem 20 may be fit together by friction fit, gluing, crimping, magnetic engagement, and the like.

(79) According to the first embodiment of the present disclosure, the stem 20 can have a longitudinal axis that is rectilinear as shown. However, in alternate embodiments, it could be curved.

(80) The present disclosure is not limited to, the broadest in accordance with the basic idea disclosed herein. It should be interpreted as having a range. Skilled artisans may implement the pattern of the non-timely manner by combining, replacement of the disclosed embodiments shape, this would also do not depart from the scope of the invention. In addition, those skilled in the art may readily change or modifications to the disclosed embodiments, based on the present specification, such changes or modifications also belong to the scope of the present disclosure will be apparent.
