  • Patent number: 8303205
    Abstract: A leakproof makeup applicator includes a main body, a rod, a collar and a bottle. The main body defines a receiving space therein. A power supply, a motor and a connector are disposed in the receiving space. The power supply electrically connects to the motor, and the connector is driven by the motor to be rotatable with respect to the main body. The rod connects to the connector concentrically and has a sealing sleeve disposed thereon. The bottle defines a liquid chamber and an opening formed at one end thereof. The opening has a plastic ring disposed on its inner periphery, in which the plastic ring defines a through hole. The rod inserts into the liquid chamber via the through hole. The sealing sleeve seals the through hole as the bottle and the collar are threadedly combined with each other.

  • Patent number: 8240316
    Abstract: A mascara applicator includes a main body, a rod and a bottle. The main body defines a receiving space therein. The main body has a power source and a reversible DC motor. The power source electrically connects to the DC motor. The DC motor includes a rotor. At least one counterweight block is disposed on the rotor so that a center of mass of the rotor is offset from the axle. The rod has a first end attached to the axle in a rotational operative relationship and a second end attached with an applicator head. The bottle defines a liquid chamber and an opening. The opening communicates with the liquid chamber, and the rod extending into the liquid chamber through the opening. The rod is sleeved with a gasket, so that the gasket blocks the opening and seals the liquid chamber when the main body is affixed to the bottle.
