Abstract

A cosmeticizing pen includes a sleeve and a guider partially received in the sleeve. A first cylinder and a second cylinder respectively longitudinally mounted to two opposite ends of the guider for containing two different cosmetics. A first head and a second head are respectively mounted to a free end of each of the first cylinder and the second cylinder. A first cap and a second cap are respectively mounted to the first head and the second head for protect the first head and the second head after use.

Claims

1. A cosmeticizing pen comprising:

a sleeve having a first series of teeth formed on an inner periphery thereof;

a guider partially rotatably received in the sleeve, the guider having a second series of teeth formed on an outer periphery thereof and engaged to the first series of teeth of the sleeve, a through hole longitudinally centrally defined in the guider and having a threaded portion formed on a first end of the guider through hole relative to the sleeve and a threaded hole defined in a second end of the guider, the threaded hole having a diameter smaller than that of the threaded portion of the through hole;

a first cylinder and second cylinder each having a first end respectively pivotally receiving the first end and the second end of the guider, a first chamber and a second chamber respectively longitudinally centrally defined in the first cylinder and the second cylinder for containing cosmetics;

a first head and a second head respectively longitudinally mounted to a second end of each of the first cylinder and the second cylinder;

a first cap and second cap respectively detachably mounted to the first head and the second head for protecting the first head and the second head after use;

a first drive set partially received in the first cylinder and extending into the guider, the first drive set including a tube with a threaded outer periphery moved along an axis thereof, a through hole longitudinally centrally defined in the tube, the tube having a first end screwed into the threaded portion of the through hole in the guider and received in the guider, the tube including a second end having a piston pivotally mounted thereon, the piston slidably received in the first chamber for squeezing the cosmetic form the first chamber to the first head, the tube having two first grooves defined in the outer periphery thereof and diametrically corresponding to each other, a first position ring sleeved on the tube and engaged to an inner periphery of the first cylinder, the first position ring having two protrusions inwardly extending therefrom and movably received in the two first groove in the tube; and

a second drive set partially received in the second cylinder and extending into the guider, the second drive set including a threaded rod moved along an axis thereof, the threaded rod having a first end screwed into the threaded hole in the guider and extending into the through hole in the tube, the threaded rod including a second end having a piston pivotally mounted thereon and slidably received in the second chamber in the second cylinder for squeezing the cosmetic from the second chamber to the second head, two second grooves longitudinally defined in an outer periphery of the threaded rod and diametrically corresponding to each other, a second position ring sleeved on the threaded rod and engaged to an inner periphery of the second chamber, the second position ring having two protrusion inwardly extending therefrom and movably received in the two second grooves in the threaded rod.

2. The cosmeticizing pen as claimed in claim 1, wherein the guider comprises a first buckle and a second buckle respectively centrally and securely disposed on the first end and the second end of the guider, the first position ring abutting against the first buckle and the second position ring abutting the second buckle.

3. The cosmeticizing pen as claimed in claim 2, wherein the guider comprises a nut mounted between the second end and the second buckle, and the threaded hole in the guider is centrally defined in the nut.

4. The cosmeticizing pen as claimed in claim 1, wherein the first cylinder comprises a third series of teeth formed on an outer periphery of the first end thereof and engaged to the first series of teeth, and the second cylinder comprises a fourth series of teeth formed on an outer periphery of the first end thereof and engaged to the first series of teeth, a total distance of the third series of teeth of the first cylinder and the second series of teeth is longer than that of the first series of teeth such that the third series of teeth and the fourth series of teeth are selectively engaged to the first series of teeth of the sleeve.

5. The cosmeticizing pen as claimed I claim 1, wherein the first cylinder has a fifth series of teeth formed on an inner periphery of the first cylinder and the first position ring engaged to the fifth series of teeth, and the second cylinder has a sixth series of teeth formed on an inner periphery of the second cylinder and the second position ring engaged to the sixth series of teeth.
