Patent Application
20070025804
The present invention relates to a multiple-function pen with a solid applicator such as a lip stick at one end and a liquid cosmetic substance such as eye-shadow or eye-liner at the other end.
A conventional cosmetic pen is shown in
However, each cosmetic pen includes only one cosmetic liquid which provides only one function so that the users have to prepare several cosmetic pens and this means the users need a large bag to receive all of the cosmetic pens.
The present invention intends to provide a multi-function cosmetic pen which includes two ends with a solid lip stick and a liquid cosmetic substance.
The present invention relates to a cosmetic pen that a hollow outer body and a hollow inner body which is received in a first end of the outer body. A lip stick unit is received in a second end of the outer body and includes a hollow sleeve and a driving member is rotatably connected to the sleeve. A base is connected between the driving member and the hollow sleeve. A first cap is removably mounted to the sleeve and has a first interior threaded section defined in an inner periphery thereof so as to be engaged with an exterior threaded section of the sleeve.
A transmission unit is received in the lip stick unit and has a threaded rod which is engaged with a threaded hole of a guide member. A section of the threaded rod is inserted into a passage defined axially in the base. A positioning member is mounted to the threaded rod and guides the threaded rod to move linearly. A piston is connected to the threaded rod so as to push cosmetic liquid in the inner body out from an applicator on an end of the inner body.
The primary object of the present invention is to provide a cosmetic pen that has a lip stick unit on one end and an applicator at the other end. The cosmetic pen can use both solid and liquid cosmetic substances.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to FIGS. 1 to 4, the cosmetic pen of the present invention comprises a cylindrical hollow outer body 10 and a hollow inner body 20 is received in a first end of the outer body 10 and has a chamber 201 defined therein which further has a first toothed surface 21. A groove 202 is defined in an inner periphery of the chamber 201 in which liquid cosmetic substance is received. A lip stick unit 3 is received in a second end of the outer body 10 and includes a hollow sleeve 30 which includes a first exterior threaded section 31. A driving member 33 is rotatably connected to the sleeve 30 and a base 32 is connected between the driving member 33 and the hollow sleeve 30. The base 32 includes a recess 322 so as to receive a lip stick. The base 32 includes a passage 321 defined axially therein and a spiral groove 313. The sleeve 30 includes a guide member 303 which is engaged with the spiral groove 313. The driving member 33 has a positioning piece 331 and the sleeve 30 includes a shoulder 302 with which the positioning piece 331 is engaged. The sleeve 30 includes a flange 301 which is engaged with the groove 202. The inner body 20 includes an applicator 22 connected to an end opposite to the lip stick unit 3. A first cap 23 is mounted onto the inner body 20 and received the applicator 22 therein.
A second cap 34 is removably mounted to the sleeve 30 and has a first interior threaded section 341 defined in an inner periphery thereof so as to be engaged with the first exterior threaded section 31 of the sleeve 30.
A transmission unit 40 is received in the lip stick unit 3 and has a threaded rod 41 which is engaged with a threaded hole 421 of a guide member 42. The threaded rod 41 has a stop ring 43 mounted thereto and the guide member 42 includes a match surface 422 with which the stop ring 43 is matched. A section of the threaded rod 41 is inserted into the passage 321 in the base 32 and a positioning member 44 is mounted to the threaded rod 41. The threaded rod 41 includes two axial guide rails 411 and the positioning member 44 includes a toothed outer surface which is engaged with the first toothed surface 21 of the inner body 20. The positioning member 44 includes two guide blocks 441 at an inner periphery thereof and the guide blocks 441 are slidably engaged with the axial guide rails 411 of the threaded rod 41 so as to guide the threaded rod 41 to move linearly. A piston 45 is connected to an end of the threaded rod 41 so that when threaded rod 41 moves, the cosmetic liquid in the chamber 201 of the inner body 2 is pushed to flow out from the applicator 22. The positioning member 44 further has a concaved ratchet surface 440 which faces the stop ring 43. A plurality of ratchets are defined in an inner periphery of the concaved ratchet surface 440 and engaged with the toothed surface 431 in the stop ring 43.
