Abstract

A cosmetic structure including a sleeve a middle section of which is formed with an annular stopper section defining a fitting hole. A cock is fitted in the fitting hole to divide an interior of the sleeve into a receiving space and an operation space, whereby a liquid cosmetic can be contained in the receiving space. A lower section of the sleeve is formed with two opposite guide slots communicating with the operation space. An operation rod is fitted through a binding hole of the cock. A brush stem is inserted in a top end of the operation rod. The top end of the operation rod protrudes from the cock into the receiving space. The receiving space has an opening in which a hollow plug with a leakproof ring is fitted. A cap body is engageable with the plug. A bottom end of operation rod has a guide seat attaching to an inner face of the wall of the operation space. Two opposite guide blocks are disposed on a circumference of the guide seat. The guide blocks extend through the guide slots. A controlling collar is rotatably fitted around the operation space. An inner circumference of the controlling collar is formed with a spiral groove in which the guide blocks of the guide seat are inlaid.

Claims

1. A cosmetic structure comprising a sleeve, an inner circumference of a middle section of the sleeve being formed with an annular stopper section defining a fitting hole, a cock having a resilient binding hole being fitted in the fitting hole to divide an interior of the sleeve into a receiving space and an operation space, whereby a liquid cosmetic can be contained in the receiving space, a lower section of the sleeve being formed with two opposite guide slots communicating with the operation space, an operation rod being fitted through the binding hole of the cock from the operation space to the receiving space, a brush stem with soft brush hairs being inserted in a top end of the operation rod, the top end of the operation rod protruding from the cock into the receiving space, a wall of the binding hole tightly resiliently abutting against the operation rod to isolate the receiving space from the operation space, the receiving space having an opening in which a hollow plug with a leakproof ring is fitted, a cap body being engageable with the plug, a bottom end of operation rod having a guide seat attaching to an inner face of the wall of the operation space, two opposite guide blocks being disposed on a circumference of the guide seat, the guide blocks extending through the guide slots and slightly outward protruding therefrom, the cosmetic structure further comprising a controlling collar rotatably fitted around the operation space, an inner circumference of the controlling collar being formed with a spiral groove in which the guide blocks of the guide seat are inlaid, whereby by means of turning the controlling collar clockwise or counterclockwise, the operation rod can ascend or descend to extend the brush hairs out of the sleeve for doing makeup or retract the brush hairs into the sleeve.

2. The cosmetic structure as claimed in claim 1, wherein the cock is made of elastic plastic material.

3. The cosmetic structure as claimed in claim 1, wherein the receiving space has an outer diameter larger than an outer diameter of the operation space to form a step section.

4. The cosmetic structure as claimed in claim 1, wherein an outer circumference of the middle section of the sleeve is formed with engaging grooves and the controlling collar has an opening formed with engaging ribs, the engaging ribs being rotatably engaged with the engaging grooves of the sleeve.

5. The cosmetic structure as claimed in claim 1, wherein an inner circumference of the opening of the receiving space is formed with an engaging groove and the hollow plug is formed with an engaging rib for engaging with the engaging groove.

6. The cosmetic structure as claimed in claim 1, wherein an opening of the top end of the plug is tapered, a bush made of resilient plastic material being tightly fitted in the tapered opening, the bush being formed with an annular angular insertion groove, an inner circumference of upper section of the bush being formed with an annular tapered thrust face, a tubular column projecting from an inner face of a top wall of the cap body to press the thrust face of the bush.

7. The cosmetic structure as claimed in claim 1, wherein the plug is further formed with insertion ribs and the cap body is formed with insertion grooves in which the insertion ribs are inlaid, whereby the cap body can be located on the plug.

8. The cosmetic structure as claimed in claim 1, wherein the cock is formed with an annular groove near a bottom end of the cock, in which the stopper section is tightly inlaid, the bottom end of the cock being formed with a flange tightly attaching to a lower face of the stopper section.

9. The cosmetic structure as claimed in claim 1, wherein the top end of the operation rod is formed with an insertion socket in which the brush stem with soft brush hairs can be inserted.

10. The cosmetic structure as claimed in claim 1, wherein the brush is a lip brush, eyebrow brush or eyelash brush.
