Device for packaging, dispensing and applying a solid or pasty block of cosmetic product The present application relates to a device for packaging, dispensing and applying a block of solid or pasty cosmetic product, comprising a longitudinal tubular case having an open first end, intended for dispensing the cosmetic product, and an opposite second end that is closed by a base accommodating a mechanism for driving a support for holding said cosmetic product in translation along the case, characterized in that the device has, at the open first end of the case, an external envelope with a longitudinal central axis offset radially with respect to a longitudinal central axis of an external envelope of the device at the opposite end of the case that is closed by the base.

Systems, methods, and new file formats are provided for printing 3D microstructures. In some implementations, a new file format is provided that defines 3D objects by a wireframe model expressed as a collection of wires. Because wires and their parameters are defined within the new file format, objects may be processed more efficiently and quickly to support 3D rendering operations. Such methods may be used to print new articles, such as eyelashes, bushes, swabs and other novel items.

Systems, methods, and apparatuses for implementing a self-contained periorbital cosmetic applicator device are described herein. For example, according to one embodiment there is a periorbital cosmetic applicator device including: a brush head portion, in which the brush head portion includes an internal liquid distribution system having distal ends of internal ducts, fluid distribution ports, and bristles, in which the distal ends of the internal ducts transport material to be applied and connect to fluid distribution ports adjacent to the base of bristles, in which the fluid distribution ports eject the material to be applied to the bristles, in which the bristles receive the material exiting from the fluid distribution ports for application to a target region on a face or body; a brush body portion, in which the brush body portion contains a reservoir for receiving material to be applied, in which the reservoir is to enclose the material to be applied, in which the reservoir receives a sealing cap at a distal end of the reservoir to retain the reservoir within the brush body portion; a brush neck portion, in which the brush neck portion serves as a connection between the brush head portion and the brush body portion, in which the brush neck portion connects proximal ends of the internal ducts to receive material to be applied, in which the material to be applied traverses through the brush neck portion from the reservoir of the brush body portion and into the internal liquid distribution system of the brush head portion via the proximal ends of the internal ducts; a reservoir connector, in which the reservoir connector portion is located between the brush neck portion and the brush body portion, in which the reservoir connector portions receives material to be applied from the reservoir of the brush body portion for transfer to the brush neck portion; and a detachable cap for sealing the brush head portion, in which the cap attaches posteriorly at the base of the brush body portion. Other related embodiments are disclosed.

A sample cosmetic product (1) having an applicator including a shell (7), incorporating a first portion (13) with a first cavity (10) and a second portion (15) with a second cavity (13) connected together so as to enable the reception of an applicator. A cover (8) is positioned on the shell to cover the first cavity and the second cavity, the cover welded around the first cavity on the first portion of the shell forming a first weld (26), and around the second cavity of the second portion of the shell forming a second weld (27). The first weld is configured to be dewelded by peeling away the cover to enable the opening of the first cavity. The packaging has a reinforcing mechanism separating the first portion and the second portion, the reinforcing mechanism is configured to prevent the dewelding of the second weld.

A cosmetics applicator made of plastic and having a bristle carrier and having bristles integrally bonded therewith as a single part, whereas the bristle carrier being a permanent magnet while the bristles as such are non-magnetic, characterized in that the bristle carrier comprises a core made of a first plastic filled with magnetic particles and forming an interface at least at the outer circumference thereof, said interface being enclosed by a layer of a second, non-magnetic plastic, wherein the first and the second plastic are preferably welded to each other and the second plastic is preferably harder than the first plastic, and wherein the second plastic is integrally connected to the bristles as a single piece.

A method for manufacturing a cosmetic product applicator including a gripping part and an applicator part having bristles or teeth. The method includes additive manufacturing (S1) by sintering a powder of a plastics material followed by depowdering (S2) and post-treatment for the removal of particles that have become detached from the cosmetic product applicator or are partially sintered, the post-treatment including blasting (S4) and ionizing blowing (S5). This method allows the removal of particles likely to be irritating, for example with a size greater than 500 micrometers, while being suitable for industrial production. The invention also relates to an associated production method.

A mobile phone case with interchangeable, removable and attachable modular make-up and cosmetics. Various embodiments of interchangeable accessory attachments include cosmetic make up compartment, cosmetics, make-up, blush, foundation, primer, lip coloring, lip gloss, lip stick, mascara, eye liner, eye shadow, lotion, skin conditioner, acne medication, tools for application, tools for removal, brush, swab, make-up pencil, make-up pen, highlighting instrument, glitter, ink, implement, pad, wipe, and/or any other make-up related accessory.

A rotary type linear reciprocating motion device includes: a driving part rotatably driven by a motor; a rotating part installed at one surface of the driving part, the rotating part transferring a rotational force of the driving part to an applicator; and a reciprocating part installed at the other surface of the driving part, the reciprocating part converting the rotational force of the driving part into a linear reciprocating motion force, the reciprocating part transferring the linear reciprocating motion force to the applicator. The driving part includes: a driving plate having both surfaces at which the rotating part and the reciprocating part are respectively installed; and a driving belt installed at an edge of the driving plate, the driving belt being in contact with a motor shaft of the motor to allow a driving force of the motor to be transferred to the driving plate by a frictional force.
