Abstract

A cosmeticizing pen includes a sleeve a guider mounted in the sleeve. Two shanks respectively longitudinally mounted to two opposite end of the guider and two drive devices respectively mounted in the two shanks. The sleeve is selectively connected to a corresponding one of the two drives to squeeze out the cosmetic in the shank that contains the corresponding drive device.

Claims

1. A cosmeticizing pen comprising:

a sleeve;

a guider selectively rotatably received in the sleeve, a through hole centrally defined in the guider, the through hole having a first threaded section and a second threaded section respectively formed on an inner periphery of the through hole, the first threaded section having a diameter greater than that of the second threaded section;

a first shank and a second shank respectively pivotally and longitudinally mounted to two opposite ends of the guider, and partially received in the sleeve, the sleeve selectively connected to a corresponding one of the first shank and the second shank;

a first drive device mounted in the first shank, the first drive device including a first actuated rod with a threaded outer periphery partially screwed into the first threaded section of the through hole in the guider, a first holder sleeved on the first actuated rod and linearly moved relative to the first actuated rod, a first piston longitudinally mounted to one end of the first actuated rod opposite to the guider; and

a second drive device mounted in the second shank, the second drive device including a second actuated rod with a threaded outer periphery screwed into the second threaded section of the through hole in the guider and partially extending into a through hole that is centrally longitudinally defined in the first actuated rod, a second holder sleeved on the second actuated rod and linearly moved relative to the second actuated rod, a second piston longitudinally mounted to one end of the second actuated rod opposite to the guider;

wherein the sleeve has a first series of teeth longitudinally formed on an inner periphery thereof, 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, the first shank and the second shank respectively having a third series of teeth and a fourth series of teeth formed thereon within the sleeve such that the first series of teeth of the sleeve is selectively engaged to a corresponding one of the third series of teeth and the fourth series of teeth.

2. The cosmeticizing pen as claimed in claim 1, wherein the first shank comprises a first chamber longitudinally defined therein and a fifth series of teeth formed on an inner periphery of the first chamber, the first actuated rod has at least one first slit longitudinally defined in the outer periphery thereof, the first holder having a teethed periphery engaged to the fifth series of teeth, the first holder having at least one first guider extending therefrom and movably received in the at least one first slit.

3. The cosmeticizing pen as claimed in claim 2, wherein the first actuated rod has two first slits defined in the outer periphery thereof and diametrically corresponding to each other.

4. The cosmeticizing pen as claimed in claim 2, wherein the guider comprises a first groove defined in one end thereof surrounding the through hole and facing the first shank, a first pusher sleeved on the first actuated rod and partially received in the first groove, the first pusher having a first ring of ratchet formed thereon out of the first groove, the first holder having a first recess defined therein facing the first pusher, the first recess having a teethed inner periphery engaged to the first ring of ratchet.

5. The cosmeticizing pen as claimed in claim 4, wherein the first pusher comprises multiple first protrusions outwardly extending therefrom to be engaged to the periphery of the first groove in the guider.

6. The cosmeticizing pen as claimed in claim 4, wherein the guider comprises a second groove defined in one end thereof surrounding the through hole and facing the second shank, a second pusher sleeved on the second actuated rod and partially received in the second groove, the second pusher having a second ring of ratchet formed thereon out of the second groove, the second holder having a second recess defined therein facing the second pusher, the second recess having a teethed inner periphery engaged to the second ring of ratchet.

7. The cosmeticizing pen as claimed in claim 6, wherein the second actuated rod has two second slits longitudinally defined in the outer periphery thereof and diametrically corresponding to each other.

8. The cosmeticizing pen as claimed in claim 2, wherein the second shank comprises a second chamber longitudinally defined therein and a sixth series of teeth formed on an inner periphery of the second chamber, the second actuated rod having at least one second slit longitudinally defined in the outer periphery thereof, the second holder having a teethed periphery engaged to the sixth series of teeth, the second holder having at least one second guider extending therefrom and movably received in the at least one second slit.

9. The cosmeticizing pen as claimed in claim 8, wherein the second actuated rod has two second slits defined in the outer periphery thereof and diametrically corresponding to each other.

10. The cosmeticizing pen as claimed in claim 1 further comprising a first head and a second head respectively longitudinally mounted to the first shank and the second shank.

11. The cosmeticizing pen as claimed in claim 10 further comprising a first cap and a second cap respectively detachably covered on the first head and the second head.
