  • Patent number: 8177452
    Abstract: A nail polish container includes an outer barrel having a dispense nozzle and a detachable refill container. The dispense nozzle includes a brush and a dispense tube seat mounted therein. The refill container contains therein a liquid content and has a top mouth receiving therein a volume-regulating valve seat and a tubular sleeve. When the refill container is fit into the outer barrel, a dispense tube of the dispense tube seat is inserted into the valve seat, whereby depression of the refill container may cause the valve to open to allow the nail polish contained in the refill container to flow, in a volume-regulated manner, to the brush for performing application of the nail polish.

  • Patent number: 8033746
    Abstract: An electrically driven powder cosmetics application device is controlled by high speed operation of a motor together with an eccentric weight block to induce vibration for facilitating uniform dispensing of powder cosmetics. The device includes a plastic container having an end forming a powder dispensing port containing therein a filter. Provided outside the dispensing port is a hollow collar fit over a dispensing device including a brush and a brush hair confiner tube with a powder outlet passage arranged therein. An opposite end of the container has a bottom receiving therein a vibration device including a rotation motor and an eccentric weight and a battery set for supplying electrical power and controlled by a switch to turn on/off vibration operation. With the vibration device turned on, the container is provided with assistance for dispensing cosmetics thereby ensuring uniform and smooth dispensing of the powder cosmetics contained in the container.

  • Publication number: 20110114112
    Abstract: The present invention relates to a lash brush that allows for adjustment of the arrangement of bristles formed on a bristle sleeve of the lash brush according to practical needs and enhances the operation of lash make-up. A bristle bar assembly includes an inner bar that is retained in an end cap by a rim member defining guide slots and an outer tube fit over and encompassing the inner bar. A front end of a bristle sleeve is coupled to an end of the outer tube and an end of the inner bar is inserted into and fixed to an inner end of the bristle sleeve. In use, through withdrawing and rotating the cap, the inner bar rotates the end of the bristle sleeve, causing twisting of a bristle tip surface formed by tips of bristles and thus realizing adjustment of the arrangement of the bristles.

  • Publication number: 20100300474
    Abstract: Disclosed is a vibratory lash brush with forward/backward rotation control. The lash brush has a handheld body containing therein a transmission motor and through the control of rotation provided by a reduction device coupled to an end of the motor, the lash brush can be put in rotation with a slow speed. An opposite end of the motor is structured to extend a spindle that carries an eccentric weight block, whereby when turned on, the lash brush induces vibration with the high speed rotation so that the brush stem provides a two-in-one novel lash brush structure that exhibits both vibration and rotation, and that is rotatable in a slow speed with a reduction device, together with high speed eccentric vibration induced in the opposite side of the motor, to realize assistance to uniform application by the lash brush, achieving a practical efficacy of eyelash curling and uniform makeup operation.

  • Publication number: 20100139677
    Abstract: A container for nail polish is disclosed. An appropriate amount of nail polish container in the container is delivered by pressing a control on the container. The container has an elongated body having a storage chamber containing nail polish, and the bottom of the elongated body is a pushing rod, allowing the bottom section of the container to rotate along the pushing rod. The pressing of the control element causes the gear member to rotate, which moves up the pushing rod and a valve plate on the valve seat squeeze the nail polish to the bristles provided at the valve seat.

  • Patent number: 6793431
    Abstract: A squeezing device for cosmetic is disclosed. The present invention relates to a container containing a make up cream or lotion, which can be squeezed out with a specific amount. The interior of the tubular body is mounted with a pushing rod, which is rotatably controlled by means of the screw threads on the pushing rod. The rotating seat rotates to push the pushing rod upward so that the make-up cream or lotion flows out. The outlet end is provided with an elastic valve plate for sealing so that the cream or the lotion steadily flows out and is automatically cut off.

  • Patent number: 6231255
    Abstract: A lipstick housing includes a barrel and a ferrule having a tube rotatably engaged in the barrel. The tube has one or more slots formed in the longitudinal direction. A seat is slidably received in the tube for holding a lipstick material and is guided to move along the tube when the tube is rotated relative to the barrel. The free end of the barrel includes a peripheral flange extended and curved radially inward and then extended downward for forming a reinforcing end portion and for preventing the barrel from being deformed by a user when the user holds the barrel.
