  • Publication number: 20230331434
    Abstract: The plastic foldable storage device is made from hollow and comb-shaped plastic plates, and includes a rectangular base plate, two first side plates extended respectively from two shorter edges of the base plate, and two second side plates extended respectively from two longer edges of the base plate. The first and second side plates are edge-to-edge joined by joining strips. Each first side plate has two folding lines along its inner surface. The first and second side plates, through the joining strips and the folding lines, are selectively folded into a level positon resting on the base plate or unfolded into an upright position to form a storage space with the base plate. The plastic foldable storage device therefore provides convenient use and storage, while offering additional advantages such as repeated usage, moisture proof, and robustness.

  • Patent number: 8647004
    Abstract: The present invention provides an improved assembling structure of intermediate tube of lipstick, which is an improvement of assembling positioning structure of intermediate tube of lipstick that realizes comfortable and smooth rotation control in out-feeding lipstick, generally including a plurality of equally divided and slightly convexly raised elastic flange plates that are formed on a circumferential surface of a rotary base to which an intermediate tube is assembled, whereby the intermediate tube, when assembled, shows a point elastic pushing positioning assembling with respect to the rotary base so that when the rotary base is rotated to control the internally received lipstick holder to raise or lower, an effect of safe use that is realized by positive engagement and shaking-free rotation control. As such, the assembling structure of lipstick is made stable and positive and comfort and safety of the use of the lipstick are ensured.

  • Patent number: 8568048
    Abstract: A bendable mascara brush which includes a container for storing mascara and a brush assembly plugging into the container. The brush assembly form a joint between a brush shaft and a main shaft. Then, a slant guiding surface is configured in front of the brush shaft and, as the brush shaft is pushed forward by the main shaft, a slant surface of the brush shaft engages the guiding surface, causing the brush shaft to tilt to a side at an angle and thereby avoiding the problem of blocking user view. Additionally, a notch is configured opposite to the guiding surface so that the tilted brush shaft is embedded into the notch and held reliably and steadily in its tilted configuration.

  • Publication number: 20120272992
    Abstract: A bristle structure of lash brush includes a bristle arrangement that can simultaneously perform brushing and makeup operations. The bristle arrangement of the lash brush is divided into two substantially halves composed of bristles of different materials and different diameters arranged in a radiating form. The bristles that are made of a material having an excellent ability of makeup material attaching functions to attach and carry the makeup material, while the other bristles that are made of a rubber material of great friction, whereby when one half applies the makeup material, the other half, by being rotated, functions to stretch the lashes, so that simple and simultaneous operations of makeup and stretching of lashes can be realized for lash makeup.

  • Publication number: 20120266907
    Abstract: An improved eyeliner applicator comprises a holding tube, an outer cap, and an outer case. The holding tube includes a buffering tube and a liquid feeding core insertedly fixed in the buffering tube. The liquid feeding core has a front end being fitted with a brush tip and a rear end communicating with a chamber of cosmetic liquid. The buffering tube is provided with a plurality of grooves, which communicate with the liquid feeding core via a plurality of through holes such that, when cosmetic liquid fed from the chamber is more than the required, excessive liquid can be diverted to the grooves, when the cosmetic liquid fed from the chamber is less than the required, the liquid stored in the grooves can be sucked back to the liquid feeding core to continuously supply liquid to the brush tip, thereby providing an steady flow to facilitate the operation.
