[0081]
[0082] In general, the use of the terms “distal” and “proximal” herein is supposed to mean that the distal side/end is the side/end facing towards the inside of the storage receptacle 200, whereas the proximal side or proximal end is the side or end facing towards the removal opening of the receptacle 200.
[0083] According to an embodiment and as shown in
[0084] According to an embodiment, the receptacle 200 may be made of a rigid material like glass, metal, hard plastic or any other material known in the art. In alternate embodiments, the receptacle 200 is made of a flexible material like flexible polymeric material or any other material known in the art.
[0085] As shown in
[0086] Inserted in the neck 204 of the receptacle 200 is a wiper 206 for wiping off excess cosmetic product from the cosmetic applicator 100. The wiper 206 also comprises an annular bead 208 on its outer surface for engaging into a corresponding annular groove 210 formed on an inside surface of the neck 204 of the receptacle 200.
[0087] The cosmetic applicator 100 comprises the applicator head 10 retained at a distal end 21 of the stem 20 for applying the cosmetic product; and the cap 30 at a proximal end 23 of the stem 20. The distal end 21 of the stem 20 includes an interior longitudinal cavity 22 for receiving and retaining the applicator head 10.
[0088] According to an embodiment of the present disclosure, the applicator head 10 and the stem 20 are fitted together by a snap fitment. In alternate embodiments, the applicator head 10 and the stem 20 are fit together by friction fit, by gluing, crimping, magnetic engagement and the like.
[0089] According to an embodiment of the present disclosure, the stem 20 can have a longitudinal axis X-X that is rectilinear as shown. In alternate embodiments, the stem is be curved.
[0090] According to an embodiment of the present disclosure, the stem 20 presents a cross-section that is circular, 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. When the stem 20 is not of circular cross-section, the cap 30 can possibly by 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 of section that is complementary to the cross-section of the stem 20.
[0091] 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 a material from which the stem 20 is made. According to an embodiment of the present disclosure, at least a part and preferably all of the applicator head 10 can be made by molding, e.g. by injection-molding or other techniques known to those of skill in the art. The applicator head may be made from materials suitable for molding including by injection molding. Materials suitable for forming the applicator head will be appreciated by those of skill in the art as including 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), and the like.
[0092]
[0093] According to an embodiment of the present disclosure, the applying member 105 is covered with application element which in this case is flocked fibers (not shown). 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 surface of the applying member 105 may be achieved by an appropriately chosen known technique, such as electrostatic flocking. The applying member 105 before being flocked is smooth on its entire surface. That is, the applying member 105 before being flocked has no surface textures, such as a wrinkle finish or a matte finish, over the entire surface thereof. To put it another way, the applying member 105 before being flocked is smooth and slippery.
[0094] Preferably, the flocking process takes place in an electrostatic field, which results in the proper orientation of the fibers. The flock on the applying member 105 provides a layer which can hold a small amount of the cosmetic product adequate for one or two applications. In alternate embodiments, the applying member 105 includes injection molded fibers, projections or grooves which are capable of holding the cosmetic product.
[0095] As shown in
[0096] According to a first embodiment of the present disclosure, the first application face 42 has a concave surface 46, wherein the concave surface 46 extends from a proximal end 41 of the applying member 105 to the distal end 43 of applying member 105. The concave surface 46 creates a volume reservoir. This volume reservoir serves as a reservoir for the cosmetic product. A significant quantity of the cosmetic product may be accommodated in said volume reservoir which is available to be applied to the user's skin or keratinous substrate.
[0097] As shown in
[0098] The inclined flat surface 48 helps in precise deposition of the cosmetic product on applying the cosmetic product on the user's skin or keratinous substrate. For example, when the cosmetic product is applied on the user's lip edge, the applicator can be used to form a perfect cupid's bow, that is, a facial feature where the double curve of a human upper lip is said to resemble the bow of Cupid, the roman god of erotic love.
[0099] According to a further aspect of the present embodiment, a hinge 45 is formed between the proximal end 41 of the applying member 105 and root 8a at a distal end 106 of the shank portion 107. The hinge 45 is formed by intersection of two cutting planes, P1 and P2; wherein one of the two cutting planes is orthogonal to the longitudinal axis X-X of the cosmetic applicator 100 or in other words one of the planes is parallel to a transverse axis Y-Y of the cosmetic applicator 100 (refer
[0100] According to an embodiment of the present disclosure, the hinge 45 is to provide flexibility, that is, to modify the stiffness of the applying member 105 which abuts against the shank portion 107 of the applicator head 10 when flexed. The flexibility provided by the hinge 45 is to give user the feeling that the cosmetic applicator 100 is very soft and resilient.
[0101] According to an embodiment of the present disclosure, the applying member 105 flexes from a non-flexed state into a completely flexed state.

The second application face 244 when seen from the proximal end 241 to the distal end 243 of the applying member 205 comprises the first convex surface 248 which is followed by the concave surface 247 which in turn is followed by the second convex surface 249.
[0105] According to an aspect of the second embodiment, the first convex surface 248 of the second application face 244 forms of a bulbous portion 254 on the second application face 244.
[0106] According to a further aspect of the present disclosure, there is drastic decrease increase in thickness of applying member 205 afterwards the bulbous portion 254 of the applying member 205. In other words, the thickness of applying member decreases from the proximal end 241 to the middle portion 253 of the applying member 205. According to an aspect of the present embodiment, a thickness of the proximal end 241 is at least twice a thickness of the middle portion 253 or the distal end 243 of the applying member 205.
[0107] According to an embodiment of the present disclosure, a concave region 253 is created due to reduced thickness between the proximal end 241 and the distal end 243 of the applying member 205. More particularly, the concave region 253 is formed between the proximal end 241 and the middle region 253 of the applying member 205 on the second application face 244. The concave region 253 creates a volume reservoir. This volume reservoir serves as a reservoir for the cosmetic product. A significant quantity of the cosmetic product may be accommodated on said volume reservoir which is then ready to be applied to the user's skin or keratinous substrate.
[0108] Further as shown in
[0109] Further, the hinge 245 is present at one side of the applicator head 201 only. Particularly, there is only one hinge 245 in the applicator head 201 limited to a single zone in a circumference of the applicator head 201 between the shank portion 207 and the applying member 205. More particularly, as shown in
