Systems, devices, and methods for a cosmetic sponge having: a tip portion at one end of the cosmetic sponge; an angled portion, where the tip portion is surrounded by the angled portion; a bulbous portion, where the bulbous portion is disposed proximate a bottom of the cosmetic sponge; and a bottom portion, where the bottom portion is surrounded by the bulbous portion; and a thermochromic pigment in at least a portion of the cosmetic sponge, where the portion of the cosmetic sponge changes from a first color at a first temperature to a second color at a second temperature.

A cosmetic applicator tip includes a base; a primary surface extending from the base, the primary surface including a height, a thickness, and a width; at least one auxiliary wall extending from the base, each auxiliary wall of the at least one auxiliary wall including a height.

A refillable cosmetic applicator with a cartridge that accommodates a refill stick which is movable in relation thereto, and an applicator main body to which the cartridge can be attached, characterized in that the cosmetic applicator comprises two couplings, namely a first coupling by means of which a rotational movement generated by the user on the applicator main part is transmitted to the cartridge in such a way that the refill stick is displaced relative to it, and a (different) second coupling, by means of which it is prevented that a rotational movement is transmitted to the cartridge any longer as soon as the cartridge can no longer follow this rotational movement.

An application container includes a leading tube, an outer tubular member, an inner tubular member fixed to the outer tubular member, and a push rod that advances within the inner tubular member and pushes the drawing material, so that a drawing material comes out from an opening of the leading tube. The outer tubular member has a through hole formed in a side surface of the outer tubular member. At least a part of the inner tubular member that is exposed from the through hole is a transparent portion through which the inside of the inner tubular member is visible. The push rod includes a visible portion that is visible from the outside of the inner tubular member through the transparent portion.

A cap can be configured to engage with cosmetic application devices (also referred to as applicators or cosmetic implements) of various sizes. The cap may include a rigid housing and a flexible body within the rigid housing comprised of elastic material. The flexible body includes a cavity that extends from an opening in the proximal end portion toward the distal end portion of the cap and varies in diameter along its length. The cap may receive an application segment of an applicator through the opening, and the inner surface of the cap can apply pressure to a surface of the applicator to form a seal between the applicator and the cap. The seal between the applicator and the cap protects the application segment from dust and debris and prevents fluid in the applicator segment from drying or hardening.

An applicator that draws fine lines and dots includes a body sleeve having a shape of an elongated tube, a first drawing tool having a first section within the body sleeve and a first tip extending out from the body sleeve, wherein the first drawing tool reduces in size at a distal end of the first drawing tool, a second drawing tool having a second section within the body sleeve and a second tip extending out from the body sleeve, wherein the second drawing tool reduces in size at a distal end of the second drawing tool, and the first drawing tool, the second drawing tool, or both first and second drawing tools have a bend to bring the first and second tips closer together.
