It can be used in.

  The inside of the bottom part may have an inclined part that prevents urine from flowing back toward the user. Moreover, it is good for each outer surface of the left side surface and the right side surface to have a curved surface shape corresponding to the shape near the inner root of the left and right thighs.

  Furthermore, it is preferable that the end edge that rises orthogonally from the bottom side of the urine receiving surface and is located near the lower abdomen of the user has a curved shape corresponding to the shape of the lower abdomen of the user.

  In addition, the urine receiving surface is provided with a connecting portion for connecting a locking portion for locking the urine storage bag adjacent to the discharge port, or a gripping portion for holding the portable toilet body is connected. Or better.

  As shown in FIG. 4, the portable toilet 100 is used in such a manner that a urine storage plastic bag 500 is attached to a cup 200 (FIG. 1) that receives urine.

  As shown in FIGS. 1 and 2, the cup 200 includes a substantially isosceles triangular prism-shaped urine receiving surface 210, an upper surface 220 positioned near the user's lower abdomen when the portable toilet 100 is used, and a urine receiving surface 210. Standing upright from one of the equilateral parts, and standing up from the other of the equilateral parts of the urine receiving face 210 and the left side face 230 in contact with the vicinity of the inner root of the left thigh when the portable toilet 100 is used. The right side 240 that contacts the vicinity of the inner root of the right thigh when using the portable toilet 100, and the bottom that faces the seat when using the portable toilet 100 that rises with a predetermined inclination from the apex of the urine receiving surface 210 250.

  A portion facing the urine receiving surface 210 is open. The end portion constitutes an end edge 260 that comes into contact with the user's genital area when the portable toilet 100 is used. On the urine receiving surface 210, a discharge port 270 formed near the top of the urine receiving surface 210, through which the plastic bag 500 serving as a urine storage bag is passed, and a hand-held portion of the plastic bag 500 adjacent to the discharge port 270 are locked. A connecting portion 290 for attaching the latching portion 300 to the cup 200 is formed.

  The cup 200 has a substantially isosceles triangular prism shape except for the protruding portion of the bottom portion 250. This is for realizing that the end edge 260 of the cup 200 is in contact with the user's genital area around the portable toilet 100 when the portable toilet 100 is used.

  The edge 260 that is a portion in contact with the user has a curved shape that fits the user and prevents urine from leaking out of the cup 200. Further, the edge 260 is chamfered because it is a part that contacts the user.

  Further, since the outer side surfaces of the left side surface 230 and the right side surface 240 are in contact with the vicinity of the inner root of the user's both feet and thighs, they have a slightly curved shape corresponding to the vicinity of the inner root of the both feet and thighs. The left side surface 230 and the right side surface 240 have been described as rising up from the equilateral part of the urine receiving surface 210. However, in the present specification, not only 90 ° in a strict sense but also 90 ° ± Includes up to about 5 °.

  As shown in FIG. 2, the outer surface of the bottom portion 250 is inclined by about 70 ° to 80 ° with respect to the urine receiving surface 210. Further, the inner surface of the bottom portion 250 has an angle of 5 ° to 20 °, preferably 5 ° to 10 °, which is lowered toward the urine receiving surface 210 when the portable toilet 100 is used, that is, when the outer surface of the bottom portion 250 is leveled. The inclined portion 280 has an angle of °. By providing the inclined portion 280, urine flows toward the discharge port 270 through the inclined portion 280 in the cup 200, so that urine can be prevented from flowing back to the user side.

  The discharge port 270 is formed near the boundary between the urine receiving surface 210 and the bottom portion 250. But you may form the discharge port 270 in the aspect containing the boundary of the urine receiving surface 210 and the bottom part 250. FIG. When the discharge port 270 is formed in such a position, urine can be smoothly discharged from the container of the cup 200 toward the plastic bag 500.

  In addition, when the cup 200 is made of synthetic resin such as ABS (Acrylonitrile Butadiene Styrene), the inclined portion 280 has a mold such that the upper end of the bottom portion 250 is thickest and gradually becomes thinner toward the discharge port 270. May be formed by manufacturing.

  Further, the connecting portion 290 is formed by cutting a screw thread inside a hole formed in the urine receiving surface 210. The locking part 300 can be connected to the connecting part 290 by screwing, and the locking part 300 can be attached and detached freely. However, the connection method by screwing the locking portion 300 is an example, and the connection method is not limited to this.
