Description

FIELD OF THE INVENTION

The present invention relates to a cosmetic device with a cap which activates an activation tube when the cap is removed from the barrel and seals the activation tube when the cap is pushed back.

BACKGROUND OF THE INVENTION

A conventional cosmetic device generally includes a barrel with a space defined therein and liquid cosmetic material is received in the space. A cosmetic piece is connected to an end of the barrel such that when the user squeezes the barrel, the liquid cosmetic material flows to the cosmetic piece to be used. In order to avoid contamination to the cosmetic piece, a cap is threadedly mounted to the barrel and includes an elongate space in which the cosmetic piece is received. The cap has to be long enough to accommodate the cosmetic piece and therefore requires a certain space when the cosmetic device is received in the user's bag or pocket.

The present invention intends to provide a cosmetic device that includes an activation tube which is operated by operation of the cap so that when the cap is removed, the activation tube is pulled to a position where the liquid cosmetic material flows to the cosmetic piece connected to the activation tube, and when the cap is re-capped, the activation tube is pushed to a sealed position where the cosmetic material is sealed in the barrel.

SUMMARY OF THE INVENTION

The present invention relates to a cosmetic device that comprises a barrel which has an interior for receiving liquid cosmetic material, and an insertion tube is inserted into a connection portion extending from an end of the barrel. The insertion tube has a through hole defined through a wall thereof and the through hole communicates with the interior of the barrel. A positioning member is connected to the connection portion and the insertion tube is received in the central hole of the positioning member. An activation tube has a longitudinal passage and extends through the positioning member. A first end of the activation tube is movably inserted into the insertion tube and a second end of the activation tube extends through the positioning member. The first end of the activation tube removably seals the through hole of the insertion tube. A mounting member is mounted to the positioning member and an inward tubular recess is defined axially in a distal end of the mounting member. The second end of the activation tube is inserted into the inward tubular recess and a cosmetic piece is inserted in the inward tubular recess and mounted to the second end of the activation tube. Two apertures are defined through the mounting member and two wings extend radially outward from the activation tube movably extend through the two apertures. Two plates are located on an outside of the mounting member and connected with the two wings. A cap is mounted to the mounting member and has two ribs extending inward from an inner periphery thereof. The ribs drive the two plates to move the activation tube away from the barrel to open the through hole of the insertion tube.

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.

Liquid cosmetic material is received in the interior 101 of the barrel 10. The connection portion 11 of the barrel 10 includes threaded outer periphery 111 and two first locking members 112 are located on the end of the barrel 10 with the connection portion 11 located between the two first locking members 112.

An insertion tube 12 is inserted into the passage of the connection portion 11 and a through hole 122 is defined through a wall of the insertion tube 12. The insertion tube 12 communicates with the interior 101 of the barrel 10. The insertion tube 12 has two open ends so that the liquid cosmetic material may enter the insertion tube 12 via the open end and the through hole 122.

A positioning member 20 is connected to the connection portion 11 and has a central hole 21. The central hole 21 of the positioning member 20 includes threaded inner periphery which is engaged with the threaded outer periphery 111 of the connection portion 11. The insertion tube 12 is received in the central hole 21 and pressed to the connection portion 11. The positioning member 20 includes two second locking members 22 on an underside thereof, and the first and second locking members 112, 22 are locked to each other to provide extra secure connection between the positioning member 20 and the barrel 10.

An activation tube 30 has a longitudinal passage 31 and extends through the central hole 21 of the positioning member 20. A first end of the activation tube 30 is movably inserted into the insertion tube 12 and a second end of the activation tube 30 extends out from the positioning member 20. The first end of the activation tube 30 removably seals the through hole 122 of the insertion tube 12 when the activation tube 30 is not yet pulled in a direction away from the barrel 10. A collar is mounted to the activation tube 30 and includes two wings 32 extending radially outward from the collar, each of the wings 32 includes a connection end 321.

A mounting member 40 is mounted to the positioning member 20 and has an accommodation space 41 in which the positioning member 20 and the activation tube 30 are accommodated. An inward tubular recess 421 is defined axially in a distal end 42 of the mounting member 40 and the second end of the activation tube 30 is inserted into the inward tubular recess 421. A cosmetic piece 60 such as a lip brush is inserted in the inward tubular recess 421 and mounted to the second end of the activation tube 30.
