Abstract

The present invention relates to a rotation on/off-type brush-tube-shaped cosmetic container, having following advantages: only with the action of turning a rotation cap, a cosmetic container may be simply opened/closed, resulting in discharging the cosmetics; though a tube container is accidentally pressurized while being used or while in storage, it still can prevent the cosmetics from being leaked. In addition, by means of the shape of a screw-type spiral groove, a seal cap and a rotation cap can be firmly fixed at the maximum rising/descending position, and can be carried out in a smooth manner during rising/descending movement.

First claim

The invention claimed is:

1. A rotation on/off-type brush-tube-shaped cosmetic container, wherein a tube container is pressurized so that cosmetics are discharged through an outlet, comprising:
a fixation body inserted into a front end of the tube container, wherein a central part of the fixation body is formed with a protruding portion for closing, a lower part of the protruding portion for closing forms a hole, and two sides of the outer periphery of an upper part of the protruding portion respectively form a screw-type spiral groove from an upper end to the central part;
a seal cap formed with a communication hole, wherein a central part of the communication hole is communicated to discharge the cosmetics, the protruding portion for closing is inserted into the communication hole when the seal cap descends from the lower part, so that the communication hole is closed, and the outer peripheral surface of the seal cap is formed with a combined protuberance which is combined with the screw-type spiral groove in a manner of being inserted into the screw-type spiral groove;
a rotation cap crossly formed with an access groove at an upper end thereof, which provides an access for the seal cap, wherein an inner part of the rotation cap is formed with a vertical guide groove combined with the combined protuberance, an upper part of the rotation cap is formed with a brush nozzle mounting portion, and the rotation cap is combined with the outer peripheral surface of the fixation body to be able to be rotated, facilitating the seal cap to rise/descend upon the rotation movement;
a brush nozzle inserted into the brush nozzle mounting portion to be fixed, and formed with more than one nozzle inserted into a brush, and
an over cap attached to the fixation body so as to be assembled and dissembled.

2. The rotation on/off-type brush-tube-shaped cosmetic container according to claim 1 , wherein
the screw-type spiral groove comprises:
an inserting groove inserted into the combined protuberance to be combined;
an upper horizontal groove facilitating the combined protuberance to be combined at the maximum rising position, and forming a space of which the perimeter is equal to or less than that of the combined protuberance, so that the combined protuberance is embedded into the space;
a lower horizontal groove facilitating the combined protuberance to be combined at the maximum descending position, and forming a space of which the perimeter is equal to or less than that of the combined protuberance, so that the combined protuberance is embedded into the space;
an inclination groove forming a space having a gap with the combined protuberance, to guarantee not to interfere the movement when the combined protuberance rises/descends; and
a bending portion forming a round-shaped curved surface from the upper horizontal groove toward the inclination groove at the position where the combined protuberance starts to descend.

3. The rotation on/off-type brush-tube-shaped cosmetic container according to claim 1 , wherein the lower part of the brush nozzle is also formed with a space portion interconnecting with a plurality of nozzles.

4. The rotation on/off-type brush-tube-shaped cosmetic container according to claim 2 , wherein the lower part of the brush nozzle is also formed with a space portion interconnection with a plurality of nozzles.
