In the present invention, it is characterized in that at an upper inner circumferential surface of the middle case 200 is provided a first screw thread 220 to be able to be screw-coupled with a coupling part 420 of the upper case 400. An upper case 400 is configured to be attached and detached through a screw combination of a first screw thread 220 and a second screw thread423 of the coupling part 420, such that it is possible to avoid the coupling structure of the middle case 200 and the upper case 400 by a traditional hinge-coupling, to reduce an assembling time in the manufacturing process and to improve productivity.
Furthermore, in a coupling process of the first screw thread 220 and the second screw thread 423 of the coupling part 420, an open upper end of the contents storage part 110 is sealed by means that a lower end of the coupling part 420 pressurizes an upper end of the sealing part 300, such that contents stored in the contents storage part 110 can be effectively prevented from being leaked.
Meanwhile, in the present invention, it is characterized in that an upper end of the middle case 200 forms a curved surface 230 as forming a downward slope to an outer side direction from an inner side, and a lower magnet 240 which fixes a securing part 412 of the upper case 400 to the curved surface 230 of the middle case 200 0 is provided at an inner side of the curved surface 23. The lower magnet 240 is configured to be placed over the entire surface of the curved surface 230 from an inner side of the curved surface 230. Due to this, after separating the upper case 400 from the middle case 200, when contacting the securing part 412 of the upper case 400 to any place of the curved surface 230, it is possible that the upper case 400 can be fixed.
The curved surface 230 forms an angle where the upper case 400 is fixed. It is preferable to form a curved surface 230 which can be fixed at an upper end of the middle case 200 in a state that the upper case 400 can be fixed with at least 90 degrees of angle slanted such that a user can look at a mirror 411 of the upper case 400 while applying makeup.
Meanwhile, when an upper end of the middle case 200 forms a plate surface instead of a curved surface 230, the upper case 400 is possible to be fixed in an angle of 90 degree with the middle case 200.
The sealing member 300, hinge-coupled to the middle case 200 to be able to open/close an open upper end of the contents storage part 110, is provided with a handle part 310 at a front surface thereof to make manipulation easy when swiveled upwards and downwards by hinge-coupling, and a reception groove 320 is provided at an upper portion thereof such that contents application member 600 such as puff can is received.
The upper case 400, encasing the contents application member 600 and detachably screw-coupled to the middle case 200, includes a cover part 410 and a coupling part 420.
The cover part 410, covering an upper portion of the middle case 200, is provided with a mirror 411 at an inner side thereof such that a user can check her face while applying makeup.
In the present invention, it is characterized in that a securing part 412 is formed with depression at one side of a side surface of the cover part 410 to be corresponded to the curved surface 230, and an upper magnet 413, which fixes the securing part 412 to the curved surface 230 of the middle case 200 by a magnetic force with the lower magnet 240, is provided at an inner side of the securing part 412. The upper magnet 413 is placed at inner side of the securing part 412, such that it is possible that the upper case 400 can be fixed to the curved surface 230 with at least 90 degrees angle slated by contacting the securing part 412 to the middle case 200 after separating the upper case 400 from the middle case 200.
The securing part 412 is made of a shape which corresponds to the curved surface 230 of the middle case 200, such that it is possible to steadily fix without the movement of the upper case 400 when contacting with the curved surface 230.
Meanwhile, at an inner side of the cover part 410 is provided a pair of protrusions 414 which forms a space where the upper magnet 413 is inserted, are respectively contacted to both sides of the upper magnet 413, and fix the upper magnet 413 to an inner side of the securing part 412. In the present invention, it was described that the upper magnet 413 is fixed by means of a pair of protrusions 414; however, it is possible to fix the upper magnet 413 to an inner side of the cover part 410 by means of a variety of fixing devices.
Furthermore, at a lower surface of the cover part 410 is provided a multitude of rotation-guiding protrusion 415 which are placed to be interlocked with a multitude of protrusions 422 of a coupling part 420 to be described later, wherein, since the rotation-guiding protrusions 415 and protrusions 422 are placed in a state of being interlocked, the coupling part 420 rotated with the rotation of the cover part 410 when a user grabs and rotates the cover part 410.
The coupling part 420, coupled to an inner side of the cover part 410, forms a penetration hole 421 such that a mirror 411 can be penetratingly installed, wherein a multitude of protrusions 422, which are interlocked with the rotation-guiding protrusions 415, are provided at an upper surface thereof so as to be rotated with the rotation of the cover part 410.
In the present invention, it is characterized in that a second screw thread 423 is formed at the coupling part 420 so as to be screw-coupled with a first screw thread 220 of the middle case 200. When the cover part 410 is rotated, the coupling part 420 is rotated along with the rotation of the cover part 410. Due to this, the first screw thread 220 and the second screw thread 423 are coupled or released from the screw coupling, such that it is possible to attach and detach the upper case 400 from the middle case 200.
A lower end of the coupling part 420 pressurizes an upper end of the sealing member 300 in a process of being screw-coupled to the middle case 200. Due to this, an open upper end of the contents storage part 110 is sealed, such that it is possible to effectively prevent the contents stored in the contents storage part 110 from being leaked.
Hereafter, with a reference of FIGS. 4 and 5, a using method of a compact container using magnets according to the first exemplary embodiment of the present invention will be described. Referring to FIGS. 4 and 5,
When grabbing the middle case 200 and rotating the cover part 410 with one hand in a state of the first screw thread 220 of the middle case 200 and the second screw thread 423 of the coupling part 420 are screw-coupled, the coupling part 420 which are coupled to an inner side of the cover part 410 rotates together. Due to this, the second screw thread 423 and the first screw thread 220 of the middle case 200 are released from the screw coupling, and thereby the upper case 400 is separated from the middle case 200.
As in the above, after separating the upper case 400 from the middle case 200, when placing the securing part 412 at the curved surface 230 of the middle case 200 to meet each other, the upper case 400 can be fixed to the curved surface 230 of the middle case 200 by magnetic attraction between the upper magnet 413 provided at an inner side of the securing part 412 and the lower magnet 240 provided at an inner side of the curved surface 230. At this time, due to a structure of the curved surface 230 which has a downward slope to an outer side direction from an inner side of the upper end of the middle case 200, the upper case 400 can be fixed with at least 90 degrees of angle to the middle case 200.
Next, after taking out the contents application member 600 from the reception groove 320, opening the sealing member 300, and smearing contents absorbed in the contents absorption member 500, a user can apply contents, looking at the mirror 411.
Namely, the present invention is configured in that, when the upper case 400 and the middle case 200 are screw-coupled or released from screw coupling, the upper case 400 forms with at least 90 degrees of angle slanted to the middle case 200 by means of magnets and is fixed to an upper end of the middle case 200. Therefore, it is possible to avoid a traditional hinge structure and provide a new structure of a compact container.
Meanwhile, referring to FIG. 6, a compact container using magnets according to the second exemplary embodiment of the present invention is characterized in that at the upper case 400 is provided the upper magnet 413 fixed at an inner side of the securing part 412, and an upper end of the curved surface 230 is made of metal material, wherein the securing part 412 of the upper case 400 can be fixed to the curved surface 230 of the middle case 200 by magnetic attraction of the upper magnet 413.
Furthermore, referring FIG. 7, a compact container using magnets according to the third exemplary embodiment of the present invention is characterized in that at the middle case 200 is provided the lower magnet 240 fixed at an inner side of the curved surface 230, and the securing part 412 of the upper case 400 is made of metal material, wherein the securing part 412 of the upper case 400 can be fixed to the curved surface 230 of the middle case 200 by magnetic attraction of the upper magnet 413.
As in the second and the third exemplary embodiment of the present invention, in case of installing a magnet at only either of the middle case 200 or the upper case 400, it is possible to fix the upper case 400 to an upper end of the middle case 200 by composing the other side with various materials which contains metal to be stuck to a magnet.
