Embodiments of the present disclosure generally relate to an applicator head for applying a product including a cosmetic, care or pharmaceutical product onto human skin or keratinous fibers, such as, for example, hair, eyebrows, nails and/or eyelashes. The product includes viscous liquid, semisolid or powder product.
Cosmetic applicators such as dip or wand applicators are known in the cosmetic industry. Cosmetic packages often include such applicators for dispensing a particular cosmetic contained in the package reservoir. The cosmetic applicator generally includes a stem with a cap at one end and an applicator head in the form of a brush, spatula or other applicator structure suitable for applying a cosmetic or a care product including viscous cosmetics, mascara, eye liner, lip gloss, hair color, wound care, skin care, under eye cosmetics, pharmaceutical and like products. One such applicator is disclosed in U.S. Pat. No. 10,888,145 B2 for applying a cosmetic product to a user's skin. The applicator head comprises a first applicator member and a second applicator member. The first applicator member is cylindrical in shape and has a cavity extending throughout a length of the first applicator member. The non-thermal member is received within the cavity of the first applicator member.
Another U.S. Pat. No. 7,481,591 discloses an applicator comprising a rod and an application surface formed of a plurality of cones. These cones have a certain elasticity and movability and can therefore massage the cosmetic product, which is stored between them into wrinkles and uneven areas of the skin of a user.
U.S. Application No. 20,200,329,846 A1 discloses an applicator head comprising a first applying member, a second applying member and a locking part. The first applying member at least partially encompasses the second applying member and wherein at least a portion of the second applying member is made of a heat transfer material to transfer the heat or cold on contact with the keratinous substrate of a user.
While such applicators are generally satisfactory, there still exists a need for an applicator head configured to apply a cosmetic product and capable of providing cooling or heating sensation on a user's skin.
In this situation, the technical task underlying the present invention is to provide an applicator head capable of substantially obviating at least some of the aforementioned drawbacks.
It is an object of the present disclosure to provide an applicator head capable of providing cooling or heating sensation on skin and is capable of providing a larger contact area on the surface being treated.
It is further an object of the present disclosure to provide an applicator head at least partially made of a thermal storage material. The applicator head has a reservoir which insulates at least one portion of the thermal storage material, thereby preventing the possibility of 360 degrees contact of an outer surface of the heat transfer material with the skin. Limiting the outer surface of the thermal storage material which makes contact with the skin increases the time of heating or cooling sensation on the skin.
It is further an object of the present disclosure to provide an applicator head having a reservoir for being loaded with product, thereby enabling the applicator head to be used for a greater length of time or enabling a greater quantity of product to be deposited more easily.
Accordingly, there is provided an applicator head used to apply a product including a cosmetic or a care product. The applicator head elongates along a longitudinal axis. The applicator head comprises a thermal member and a secondo or non-thermal member. The thermal member is made of a thermal storage material such as metal, ceramic, metal alloy, or a stone. The thermal member may be used for massaging the user's skin. The thermal member defines at least a sidewall of the applicator head and the non-thermal member defines at least a distal surface of the applicator head. The thermal member has a cavity that extends through at least a portion of a length of the thermal member. At least a portion of the non-thermal member is received and retained within the cavity of the thermal member.
According to an aspect of the present disclosure, the cosmetic or care product includes viscous cosmetics, mascara, eyebrow powder, lip gloss, hair color, skin care, under eye cosmetics, pharmaceutical and like products. The applicator head is intended to be retained at a distal end of the stem.
According to another aspect of the present disclosure, the thermal member comprises a proximal portion and a distal portion. The proximal portion is formed as a shank portion that is configured to be received within a cavity of a stem. The distal portion of the thermal member is configured to be located outside the stem and is formed as a first applicator portion that is accessible to the user for application purpose.
According to yet another aspect of the present disclosure, the first applicator portion of the thermal member includes at least two main faces i.e. a front face, and a rear face. Further, the first applicator portion also comprises a right-side face, and a left side face. The front face includes a proximal surface and a distal surface. The distal surface extends from a distal end of thermal member and/the applicator head towards a front side of the applicator head. The distal surface is an inclined surface that extends along at least 50% of a length of the front face. In a preferred embodiment, the distal surface of the front face of thermal member is concave and the proximal surface of the front face is convex.
According to yet another aspect of the present disclosure, the rear face of the first applicator portion of the thermal member provides a large convex surface that can be used for massaging. More particularly, the rear face of the first applicator portion is curved along the longitudinal axis of the applicator head as well as in a direction orthogonal to the longitudinal axis of the applicator head.
According to yet another aspect of the present disclosure, the distal end of the thermal member is slightly off-centred with respect to the longitudinal axis towards the rear face of the first applicator portion. In various embodiments of the present disclosure, however, the distal end of the thermal member and/or the applicator head may or may not be located at the longitudinal axis.
According to yet another aspect of the present disclosure, the distal surface of the first applicator portion has a drop shape with an apex forming at the distal end thereof. However, in alternate embodiments the distal surface of the first applicator portion may have any other desirable shape.
According to yet another aspect of the present disclosure, an opening for the cavity is defined on the distal surface of the first applicator portion of the thermal member. In a preferred embodiment, the distal surface is curved and inclined, the opening is also extends oblique with respect to the central longitudinal axis of the applicator head.

In various embodiments, the first applicator portion of the thermal member may include at least one application element adapted to convey and apply cosmetic product. In such a case the application element may be tine, projection, bristle, flocking, rib, groove, disc, slit, cut, hole, dimple, foam or other surface features or surface treatments (e.g., abrading) that are suitable for combing and/or loading, transporting and applying cosmetic product.
According to an embodiment of the present disclosure, the non-thermal member is an insulator fabricated from a group of materials consisting of plastic, wood, rubber, sintered or porous material and/or combinations thereof.
According to yet another aspect of the present disclosure, the non-thermal member comprises an elongated rod portion and a second applicator portion. When the non-thermal member is received within the cavity of the thermal member, the second applicator portion projects or extends out from the opening of the cavity at the concave distal surface of the first applicator portion of the thermal member, and a major portion of the elongated rod portion is housed within the cavity of the thermal member.
According to an aspect of the present disclosure, the second applicator portion is connected (e.g. fixedly) to, or molded integrally with the elongated rod portion.
According to an embodiment of the present disclosure, the elongated rod portion of the non-thermal member has a length greater than the length of the cavity of the thermal member and therefore, the elongated rod portion extends out from a proximal end of the cavity of the thermal member.
According to an embodiment of the present disclosure, the second applicator portion extends along a plane. In a preferred embodiment, the plane is a curved plane. The plane of the second applicator portion enables it to closely match the plane of the distal surface of the first applicator portion and provides a better fit once assembled. In a preferred embodiment, specifically, the second applicator portion is provided an upper surface and a bottom surface, and wherein the upper surface is a continuously concavely curved surface and the bottom surface is a convexly curved surface. The bottom surface is designed and dimensioned to closely contact the distal surface of the first applicator portion of the thermal member. The second applicator portion is drop-shaped similar to the size of the distal surface. The second applicator portion is shaped and dimensioned to fit over and cover the distal surface of the first applicator portion. The elongated rod portion extends downwards from the bottom surface. The upper surface of the second applicator portion of the non-thermal member is configured to apply/spread the product on the user's skin.
According to yet another aspect of the present disclosure, in use, when the applicator head is withdrawn from the receptacle, the wiper cleans the applicator head in a manner such that an optimal amount of product is retained on the upper surface of the second applicator portion so that a user may use the second applicator portion of the non-thermal member to transfer product to a human keratinous surface. Thus, the upper surface of the second applicator portion 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.
According to yet another aspect of the present embodiment, at least a part of the upper surface of the second applicator portion comprises flocking. However, in an alternate embodiment of the present disclosure, the upper surface of the second applicator portion may not be flocked.
In various embodiments, the concavely curved upper surface of the second applicator portion may comprise projections, ribs, grooves, other surface features or surface treatments (e.g., abrading) that are suitable for loading, transporting and applying cosmetic product.
According to yet another aspect of the present embodiment, the elongated rod portion of the non-thermal member can be retained within the cavity of the thermal member, by locking means known in art such as a j-lock, a threaded engagement, an interference engagement, magnetic engagement or the like. In a preferred embodiment, the thermal member and the non-thermal member are secured to each other by snap-fitment. Particularly, the thermal member may include an annular projection on its inner surface and the elongated rod portion of the non-thermal member may include an annular recess and an annular flange adjacent to said annular recess. When the applicator head is assembled, the elongated rod portion of the non-thermal member is inserted into the cavity of the thermal member through the concave distal portion of the thermal member, the annular projection of the thermal member is snap fitted into the corresponding annular recess of the non-thermal member, and thus the further insertion of the non-thermal member with respect to the thermal member is limited. Further, the annular flange of the non-thermal member is locked against the annular projection making removal of the non-thermal member difficult towards the opening.
In an alternate embodiment, the annular projection may be on the non-thermal member in which case, the annular recess is on the thermal member.
According to an aspect of the present disclosure, there are provided complimentary orientation features on the thermal member and on the non-thermal member to orient the non-thermal member with respect to the thermal member in a predetermined desirable position. Preferably, the non-thermal member is so oriented that an apex of the non-thermal member is always in line with an apex of the thermal member. In a preferred embodiment, the elongated rod portion has a rectangular portion located close to the second applicator portion that corresponds to a rectangular portion of the cavity near the opening which helps to orient and prevent the rotation of the second applicator portion with respect to the thermal member.
According to an aspect of the present disclosure, there is provided a cosmetic package associated with the applicator head and comprises a receptacle for holding a product and an applicator assembly. The applicator assembly comprises the applicator head, a stem, and a cap. The cap of the applicator assembly has threads that can be screwed onto threads, formed on a neck of the receptacle.
