In the manufacture of certain cosmetics packaging, small metal pans are used to carry the cosmetic material, and these are incorporated in cosmetics carriers. The cosmetic material is initially in a powder form that is compressed into the pan prior to the pan being assembled into a carrier A multi-pan insertion tool includes a control plate and one or more interface plates that can, in turn, be attached to the control plate. Each interface plate corresponds to a different pan configuration. The interface plate includes a plurality of protrusion sites that each correspond to a single pan. An air passage from each protrusion site passes through the tool to the valve on the control plate that is controlled by an operator (either open or closed). A vacuum hose is attached to the valve to create the necessary vacuum/suction. The operator can then use the tool to pick up multiple pans at once, using suction, and then deposit the pans into a press for powder loading and then compression of the powder.

A composition is disclosed that includes pure silk fibroin-based protein fragments that are substantially devoid of sericin, wherein the composition has an average weight average molecular weight ranging from about 17 kDa to about 38 kDa, wherein the composition has a polydispersity of between about 1.5 and about 3.0, wherein the composition is substantially homogeneous, wherein the composition between 0 ppm to about 500 ppm of inorganic residuals, and wherein the composition includes between 0 ppm to about 500 ppm of organic residuals.

An application brush for a cosmetic formula comprising: i) a base having a central axis and including a top surface that is perpendicular or substantially perpendicular to the central axis and a bottom that is spaced apart from the top surface along the central axis; and ii) a bundle of bristles that is mounted on the bottom of the base. Tips of bristles forming the bundle of bristles cooperate to define a virtual plane that is perpendicular or substantially perpendicular to the central axis, and the virtual plane has an oval shape.

A replaceable makeup box structure is disclosed herein. It comprises a main body having a sheltered space and an open space for placing a makeup tray, a lid pivotally connected to the main body, and an elastic member disposed in the sheltered space to allow the makeup tray to be ejected for replacement.

A cosmetic container that grinds and dispenses a content is disclosed. The cosmetic container includes: an inner container having an interior space filled with a content; a dial that is rotatably coupled at an upper part of the inner container and includes a dispensing hole for dispensing the content and a cutter for grinding the content; a screw that is positioned at a lower part of the dial within the interior space and rotates together with the dial; a piston inserted around the screw to ascend and descend within the interior space; and an elastic member that is positioned at a lower part of the piston and pushes the piston upward. The piston is screw-joined with the screw to maintain a particular height, and rotating the dial disengages the screw joint between the piston and the screw to allow the piston to be moved upward by the elastic member.

The present invention relates to a set comprising a makeup product and a cosmetic applicator for applying this product, the applicator comprising a stem and an application member borne by the stem, the latter comprising a flexible portion (14) of wavy shape, of flattened cross section on a major axis, the flexible portion comprising a succession of elementary patterns, the flexible portion (14) having its angular deflection about the major axis limited by elementary patterns coming into mutual abutment.
