The cosmetic applicator includes a flexible application member which is manufactured independently in a first shape. The cosmetic applicator includes a stem which is a cylindrical hollow body configured to receive the application member. The application member is configured to attain a second shape when constrained within the stem. The application member includes an elongated base member and an applicator head attached to a first side of the base member. ## Claims ### Claim 1 A cosmetic applicator comprising: a stem having a hollow elongated body; the stem having a distal end and a proximal end; a handle attached to the proximal end of the stem; an application member attached to the distal end of the stem, the application member comprises an elongated base member and an applicator head attached at a first end of the elongated base member; wherein the stem has a longitudinal opening at the distal end; wherein the applicator head is flexible and has a first shape; wherein the applicator head is configured to attain a second shape when the applicator head is constrained within a channel of the longitudinal opening of the stem; wherein the applicator head includes a plurality of projecting elements for holding and discharging a cosmetic product; wherein a predetermined distance is maintained between free ends of the plurality of projecting elements in the first shape of the applicator head; and wherein the predetermined distance between free ends of at least two of the plurality of projecting elements is reduced when the applicator head fits into the channel of the longitudinal opening of the stem. ### Claim 2 (depends on 1) A cosmetic applicator according to claim 1, wherein the application head is curved in the first shape and is straight in the second shape. ### Claim 3 (depends on 1) A cosmetic applicator according to claim 1, wherein the longitudinal opening is disposed on one side of the stem. ### Claim 4 (depends on 1) A cosmetic applicator according to claim 1, wherein the plurality of projecting elements is selected from a group of tines, bristles and flocking. ### Claim 5 (depends on 1) A cosmetic applicator according to claim 1, wherein the plurality of projecting elements includes tines that are hook shaped. ### Claim 6 (depends on 1) A cosmetic applicator according to claim 1, wherein the plurality of projecting elements is disposed only on one side of the applicator head and wherein the plurality of projecting elements projects out from the longitudinal opening of the stem when the application member is fitted into the stem. ### Claim 7 (depends on 1) A cosmetic applicator according to claim 1, wherein the applicator head comprises one or more grooves that extend in a width wise direction of the applicator head and wherein the grooves act as hinges enabling the applicator head to deform easily. ### Claim 8 (depends on 1) A cosmetic applicator according to claim 1, wherein the longitudinal opening extend at an angle with respect to a longitudinal axis of the cosmetic applicator. ### Claim 9 (depends on 1) A cosmetic applicator according to claim 1, wherein the applicator head includes a plurality of through holes extending in width wise direction of the applicator head. ### Claim 10 (depends on 1) A cosmetic applicator according to claim 1, wherein the plurality of projecting elements extends from a convex or a concave side of the applicator head. ### Claim 11 (depends on 1) A cosmetic applicator according to claim 1, wherein the stem includes a number of grooves on an inner surface at the distal end of the stem and wherein the applicator head includes a number of ribs; and wherein the number of ribs are configured to align with the number of grooves to lock the applicator head and the application member within the stem. ### Claim 12 (depends on 1) A cosmetic applicator according to claim 1, wherein a height of the applicator head is substantially equal to a length of the longitudinal opening of the stem. ### Claim 13 (depends on 1) A cosmetic applicator according to claim 1, wherein the applicator head has a larger outer diameter than an outer diameter of the base member. ### Claim 14 (depends on 1) A cosmetic applicator according to claim 1, wherein a cap is provided at a tip of the applicator head and a cross section of the cap is similar to a cross-section of the stem. ### Claim 15 (depends on 1) A cosmetic applicator according to claim 1, wherein the predetermined distance between the free ends of the plurality of projecting elements is based on one or more parameters selected from a group of parameters including material, thickness and desirable density of the plurality of projecting elements. ### Claim 16 A cosmetic applicator comprising: a hollow stem, the hollow stem having a distal end and a proximal end; a handle attached to the proximal end of the hollow stem; an application member attached to the distal end of the hollow stem, the application member comprises an elongated base member and an applicator head attached at a first end of the elongated base member; wherein the hollow stem has a longitudinal opening at its distal end; wherein the applicator head is flexible and has a first shape; wherein the applicator head is configured to attain a second shape when the applicator head is constrained within a channel of the longitudinal opening of the hollow stem; and wherein a length of the application member is greater than a length of the hollow stem. ### Claim 17 (depends on 16) A cosmetic applicator according to claim 16, wherein the applicator head is curved in the first shape and is straight in the second shape. ### Claim 18 (depends on 16) A cosmetic applicator according to claim 16, wherein to fit the application member within the hollow stem, a second end of the elongated base member is inserted into the hollow stem from an opening at the distal end of the hollow stem and the elongated base member is then pulled through an opening at the proximal end of the hollow stem such that the applicator head fits inside the hollow stem and a portion of the applicator head projects out from the longitudinal opening of the hollow stem. ### Claim 19 A cosmetic applicator comprising: a hollow stem; the hollow stem having a distal end and a proximal end; a handle attached at the proximal end of the hollow stem; an application member attached at the distal end of the hollow stem, the application member comprises an elongated base member and an applicator head attached at a first end of the elongated base member; wherein the hollow stem has a longitudinal opening at the distal end; wherein the applicator head is flexible and has a curved shape; wherein the applicator head includes at least one concave side and at least one convex side; wherein a plurality of projecting elements for holding and discharging a cosmetic product is present on either the at least one concave side or the at least one convex side; wherein the at least one concave side or the at least one convex side having the plurality of projecting elements deforms resulting in formation of a plurality of curved portions, when the applicator head is constrained within a channel of the longitudinal opening of the hollow stem. ### Claim 20 (depends on 19) A cosmetic applicator according to claim 19, wherein a predetermined distance between free ends of at least two of the plurality of projecting elements changes when the applicator head fits into the channel of the longitudinal opening of the hollow stem.
