Abstract

A liquid lipstick case comprises a body having a space or container for containing a liquid lipstick therein, an output part coupled to the one end of the body for supplying the liquid lipstick to the outside, and an adjustment part coupled to the other end of the body for adjusting an amount of the liquid lipstick outputted through the output part.

Description

TECHNICAL FIELD

The present invention concerns a lipstick, and more particularly, a liquid lipstick case that is capable of maintaining the properties of a liquid lipstick without any change and preventing a brush that supplies the liquid lipstick to the outside from being hard, so that a user can paint his or her lips in a more convenient manner.

BACKGROUND ART

Generally, most lipsticks have a hard lipstick core, a core support bar for supporting the lipstick core such that the lipstick core is exposed to the outside, and a screw for moving the core support bar upward and downward. The core support bar moves through the use of the screw and the lipstick core is thus exposed to the outside.

Such the type of lipstick has the lipstick core that mostly contacts the air, such that there occur some problems that the peculiar properties of the lipstick may be easily varied and the real use time of the lipstick may be thus shortened.

To solve the above problems, there have been proposed a liquid lipstick and a container for containing the liquid lipstick therein. According to one prior art liquid lipstick, there are provided a liquid lipstick, a container in which the liquid lipstick is contained, and a brush for painting the liquid lipstick on user's lips.

However, the one prior art liquid lipstick has a problem that if the brush with the liquid lipstick thereon is exposed in the air for a predetermined time of period, it may be readily tough.

To solve the above problem as mentioned in the one prior art liquid lipstick, another prior art liquid lipstick as disclosed in Korean Utility Model Registration No. 20-0200606 suggests a dispenser case that is provided with an absorbing member for supplying the liquid lipstick to the outside. However, another prior art liquid lipstick still has a problem that if the absorbing member is exposed in the air for a predetermined time of period, it may be readily tough. That is to say, the absorbing member contains the remaining liquid lipstick thereon after painting and, even though it is closed with a cover, it is exposed to the air existing between the cover and the absorbing member, with a result that it gets hard.

FIG. 3 is a sectional view of the liquid lipstick case of FIG. 1. [0025]
The output [0026] part coupling part 10A of the body 10 is provided with a stepped opening 11 near the container 10B, a screw 12 on the inside wall toward the outside from the stepped opening 11, an inner wall edge jaw 13 outside the screw 12 and an outer edge coupling groove 16 for coupling to the cover 30.
In addition, the adjustment [0027] part coupling part 10C of the body 10 is provided with a spline groove 14 disposed on the inner wall thereof for coupling to the adjustment part and an inner wall edge groove 15 on the inner wall thereof toward the outside from the spline groove 14.
The [0028] head 20 on the output part is provided with key seats 21 disposed on the inner walls facing each other, an outer edge groove 23 disposed on the outside edge thereof for coupling to the inner wall edge jaw 13 of the output part coupling part 10A and a jaw 22 disposed on the outside edge thereof for insertion by a predetermined length into the output part coupling part 10A. In that case, the head 20 is coupled in manner to be rotated relative to the output part coupling part 10A.
The [0029] brush support bar 40 is provided with an intermediate portion 40B of a hollow type, into which the lipstick liquid flows, a brush fixing portion 40A disposed on the one end of the intermediate portion 40B for fixing the brush 90 and a screw portion 40C disposed on the other end of the intermediate portion 40B for coupling to the screw 42 on the inner wall of the output part coupling part 10A. In that case, the brush fixing portion 40A is provided with an edge jaw 42 of a stick type disposed on the inner wall thereof for fixing the brush 90 and keys 41 disposed on the outside thereof for coupling to the key seats 21 of the head 20.
The [0030] cover 30 is provided with an inner wall edge locking projection 33 for coupling to the outer edge coupling groove 16 of the output part coupling part 10A, a jaw 32 for insertion into the inside of the inlet of the head 20 and a silicon rubber 31 disposed on the interior of the jaw 32 for stopping the inlet of the head 20 and for protecting the brush 90.
On the other hand, the [0031] handle grip 50 is provided with an internal thread 51 of a hollow type disposed at a predetermined position thereof, into which the screw bar 70 is moved, for coupling to the screw bar 70, an edge locking projection 55 disposed on the external surface thereof for rotatably coupling to the inner wall edge groove 15 of the adjustment part coupling part 10C of the body 10, a plurality of external jaws 54 disposed on the outer edge periphery on the one end thereof for coupling to the inside screw 60, and a coupling groove 56 disposed to correspond with the stopper on the other end thereof, for coupling to the stopper.
The [0032] inside screw 60 of the adjustment part is provided with a spline 61 disposed on the outer periphery for coupling to the spline groove 14 of the adjustment part coupling part 10C, an internal thread 62 disposed in the interior thereof for coupling to the screw bar 70 and a plurality of internal jaws 64 disposed on the inner wall thereof for coupling to the plurality of external jaws 54 of the handle grip 50. If the handle grip 50 rotates, friction between the external jaws 54 of the handle grip 50 and the internal jaws 64 of the screw 60 is caused to thus generate an operation noise.
The [0033] screw bar 70 is provided with a body 72 with an external thread 72 thereon and a coupling portion 73 disposed on the end of the body 72 for coupling to the piston 71.
The [0034] piston 71 is coupled with the coupling portion 73 of the screw bar 70 and as the screw bar 70 moves, comes in contact with the inner wall of the container 10B, thereby moving in the interior thereof.
Now, explanations of the operation way of the liquid lipstick case according to the present invention, at the time when used for painting and the shape of the liquid lipstick case will be described. [0035]
FIG. 4 is a perspective view at the time when the liquid lipstick case of FIG. 1 is used, and FIG. 5 is a sectional view of the liquid lipstick case of FIG. 4. [0036]
If the [0037] cover 30 is separated from the liquid lipstick case and the head 20 thus rotates against the body 10, at the time of painting, the brush 90 and the brush support bar 40 move to the end of the output part coupling part 10A. To suck the liquid lipstick onto the brush 90, the handle grip 50 rotates, such that the liquid lipstick case as shown in FIG. 1 at the state of being kept is changed into that as shown in FIG. 4 at the state of being used.
In more detail, if the [0038] head 20 rotatably coupled to the output part coupling part 10A rotates relative to the body 10 and the output part coupling part 10A of the liquid lipstick case, the brush support bar 40 moves to the end of the head 20. Next, the keys 41 of the brush fixing portion 40A are inserted into the key seats 21 of the head 20 and slid to move along the key seats 21. Therefore, if the head 20 rotates, the brush support bar 40 rotates with the rotation of the head 20. And, the key seats 21 guide the movement of the keys 41, and the screw portion 40C of the brush support bar 40 is pitched and moved along the inner wall screw 12 of the output part coupling part 10A. As a result, the brush support bar 40 and the brush 90, which is fixed in the brush fixing portion 40A of the brush support bar 40, move to the end of the head 20, as shown in FIGS. 4 and 5.
In that case, since the [0039] brush 90 and the tube 80 fixed are made of an elastic material, they expand as the brush 90 moves to the had 20 such that the container 10B and the brush 90 can be connected to each other.
On the other hand, in the state where the output part operates if the adjustment part operates to provide the liquid lipstick to the [0040] brush 90, a predetermined amount of liquid lipstick is sucked to the brush 90.
In more detail, if the [0041] handle grip 50 that is rotatably coupled to the adjustment part coupling part 10C of the liquid lipstick case rotates relative to the body 10 and the adjustment part coupling part 10C, the screw bar 70 moves according to the relative movement to the internal thread 51 of the handle grip 50. Subsequently to this, the piston 71 fixed on the end of the screw bar 70 moves toward the output part along the wall of the container. The movement of the piston 71 allows the formation of a predetermined pressure in the interior of the container, such that the liquid lipstick in the container is supplied to the brush 90 through the tube 80.
In that case, the [0042] outer edge jaw 55 of the handle grip 50 is rotatably coupled to the edge groove 15 of the adjustment part coupling part 10C, and when the handle grip 50 rotates, the plurality of external jaws 54 are slid on the plurality of internal jaws 64 of the inside screw 60, thereby generating click sounds.
After painting the lips in the above state, operations opposite to the above operations are needed for keeping the liquid lipstick case. [0043]
On the other hand, the moving distance of the [0044] piston 71 according to the movement of the handle grip 50 in the liquid lipstick case of the present invention is varied upon the pitches of the threads formed on the handle grip 50, the screw bar 70 and the inside screw 60.
Industrial Applicability [0045]
As set forth in the foregoing, a liquid lipstick case according to the present invention is capable of preventing the liquid lipstick from being in contact with the external air, thereby enabling the brush to which the liquid lipstick is sucked not to be hard, rotating its handle grip to allow the variation of the pressure of the liquid lipstick in its container, thereby enabling the output of the liquid lipstick from the brush, whereby the painting on the lips can be carried out in more easy manner and the amount of the liquid lipstick retained in the container can be all consumed. [0046]
While the preferred embodiment of the present invention has been described with reference to a specific liquid lipstick case, the embodiment may be applied to, for example, foundation cases or containers for cosmetic, coordinate, paint and so on. [0047]
