    MODE FOR INVENTION

    [0016] In FIGS. 1 and 2, an opening and closing device according to a first embodiment of the present invention includes a magnet 20 which is sewed onto an inner fabric 10 of an urination hole, and a magnetic material 21 which is formed of a magnet or a metal piece and is sewed onto an outer fabric 11. The magnet 20 and the magnetic material 21 have a coated part 30 covered with synthetic resin film. The coated part 30 has a thickness that does not interfere with the magnetic force of the magnet 20 directing toward the magnetic material 21. So, two synthetic resin films can be thermally bonded on each of sides of the magnet 20 and the magnetic material 21 in close contact with each other or can be sealed in a state of being embedded in an envelope-shaped film.

    [0017] Moreover, the coated part 30 extends to the outer peripheries of the magnet 20 and the magnetic material 21, and the extending portion is sewed into the interior of the inner fabric 10 and the outer fabric 11 through a sewing part 40. Therefore, the magnet 20 and the magnetic material 21 are not exposed to the outside of the fabric. Additionally, the coated part 30 wrapping the magnet 20 has a plurality of fine protrusions 31 formed on the surface thereof to create gaps between the magnetic material 21 and the magnet 20. Thus, hairs can easily escape through the gaps, so the hairs are not pulled or plucked while the urination hole of the underwear is closed.

    [0018] FIG. 3 illustrates an opening and closing device according to a second embodiment of the present invention. The second embodiment has the same configuration as the first embodiment except that the outer periphery of the coated part 30 wrapping the magnet 20 and the magnetic material 21 is sewed onto the outside of the inner fabric 10 and the outer fabric 11 through a sewing part 40.

    [0019] FIG. 4 illustrates an opening and closing device according to a third embodiment of the present invention. The magnet 20 and the magnetic material 21 are respectively formed in a ring shape having a central through-hole 22. Each of the magnet 20 and the magnetic material 21 has a coated part 30 covered with synthetic resin film. The through-hole 22 is blocked by the coated part 30. The coated part 30 covering the through-hole 22, and the inner fabric 10 or the outer fabric 11 are coupled through a rivet bonding part 41, so the magnet 20 and the magnetic material 21 are fixed to the corresponding fabric. In addition, the coated part 30 covering the magnet 20 has a plurality of fine protrusions 31 formed on the surface thereof to create gaps between the magnetic material 21 and the magnet 20. Thus, hairs can easily escape through the gaps, so the hairs are not pulled or plucked while the urination hole of the underwear is closed.

    [0020] FIG. 5 illustrates an opening and closing device according to a fourth embodiment of the present invention, which has the same configuration as the third embodiment. However, the fourth embodiment differs from the third embodiment in that the magnet 20 and the magnetic material 21 are fixed to each of the fabrics 10 and 11 through a sewing part 40 without using the rivet bonding part 41 to the coated part 30 blocking the through-hole 22.

    [0021] FIG. 6 illustrates an opening and closing device according to a fifth embodiment of the present invention. Each of the magnet 20 and the magnetic material 21 has a coated part 30 covered with synthetic resin film. The opposing surfaces of the magnet 20 and the magnetic material 21 are wrapped and fixed by an incorrodible non-ferrous metal covering 50, and the outer circumference of the covering 50 has a U-shaped fixation groove 52 bent towards the respective fabrics 10 and 11. In case of the fabrics 10 and 11, while a fixation ring 60 having a fixation piece 61 is compressed toward the covering ring 50, the fixation piece 61 is compressed toward the corresponding fixation groove 52, so the magnet 20 and the magnetic material 21 are fixed to the inner fabric 10 and the outer fabric 11 through the fixation ring 60 and the cover ring 50.

    [0022] In addition, the covering 50 on which the magnet 20 is fixed has a plurality of fine protrusion 51 formed on the opposing surface facing the magnetic material 21, so the coverings 50 formed on both sides are not in close contact with each other but maintain a gap therebetween. Thus, hairs can easily escape through the gaps, so the hairs are not pulled or plucked while the urination hole of the underwear is closed.

    [0023] FIG. 7 illustrates an opening and closing device according to a sixth embodiment of the present invention, wherein the magnet 20 and the magnetic material 21 are formed in a ring shape having a central through-hole 22, and a coated part 30 covered with synthetic resin film. The opposing surfaces of the magnet 20 and the magnetic material 21 are wrapped and fixed by an incorrodible non-ferrous metal covering 50. Each covering 50 extends up to the through-hole 22 to block the through-hole 22, and the center of each covering 50 has a pin hole 53 formed to communicate with the through-hole 22. Furthermore, in case of each of the fabrics 10 and 11, while a fixation ring 60 having a fixation pin 62 is compressed toward the covering ring 50, the fixation pin 62 is compressed toward the corresponding pin hole 53, so the magnet 20 and the magnetic material 21 are fixed to the inner fabric 10 and the outer fabric 11 through the fixation ring 60 and the cover ring 50.

    [0024] In addition, the covering 50 on which the magnet 20 is fixed has a plurality of fine protrusion 51 formed on the opposing surface facing the magnetic material 21, so the coverings 50 formed on both sides are not in close contact with each other but maintain a gap therebetween. Thus, hairs can easily escape through the gaps, so the hairs are not pulled or plucked while the urination hole of the underwear is closed.
