  However, the above-described conventional toilet for infants causes problems as described below. That is, the pot of Patent Document 1 has a toilet bowl pot larger than the toilet seat opening simply placed under the toilet seat and does not fit into the toilet seat. There is room for improvement. In the simple toilet of Patent Document 2, the concave portion formed in the inner container functions as a handle. This handle is for sliding the inner container forward and removing it from the toilet body. The vessel cannot be transported. In addition, the inner container is placed horizontally in the shape of a Japanese-style toilet bowl, and the front part of the inner container protrudes forward from the toilet seat and widens widely. It is. Furthermore, since the protrusion is integrally formed at the front part of the inner container, the inner peripheral surface of the inner container cannot be suitably covered with a disposable filth sheet, and cleaning of the inner container with excrement stuck is troublesome. .

  In the infant toilet of Patent Document 3, the crotch of the infant hits the front end of the pot. In addition, the pot is inserted from above the toilet seat, and the upper edge of the pot is engaged with the inner edge of the toilet seat, so that the upper edge of the pot is wider than the inner edge of the toilet seat, and the upper edge of the pot is the toilet seat A step is formed on the upper surface of the substrate. Therefore, it is not comfortable for an infant. Further, since the protruding portion is integrally formed at the front portion of the pot, it is impossible to cover the inner peripheral surface of the pot with a disposable filth sheet, and it is troublesome to clean the pot where excrement is stuck.

  In the child toilet of Patent Document 4, since a handle is not formed in the container that receives the child's excrement, it is inconvenient to take out the container from the toilet seat (stool) and the support base. Further, since the container is inserted from above the toilet seat, the upper edge of the container forms a step on the upper surface of the toilet seat. Therefore, it is not comfortable for an infant.

  The infant's chamber of Patent Document 5 is a method in which the middle lid is dropped from above the toilet seat, so there is no handle in the middle collar, and the operation of taking out the middle collar from the toilet seat body is inconvenient. Since the portable toilet of Patent Document 6 has no handle in the portable toilet container, it is inconvenient to take out the portable toilet container from the portable toilet body. As described above, the conventional toilet for infants has room for improvement in several respects.

  In view of the above-mentioned circumstances, the present invention hygienically receives the excrement of an infant, the toilet seat is difficult to get dirty, the toilet seat is comfortable to sit on, and the area in which the center lid becomes dirty is reduced to efficiently wash the center lid. Infant toilets that can be easily attached to the inner surface of the inner lid of a bag-like disposable sheet and can be easily taken out and transported from the toilet seat (container, pot) The purpose is to provide.

  To this end, an infant toilet according to the present invention has a toilet seat having an opening in the center and capable of supporting an infant's buttocks, and a toilet seat having an inner wall portion depending from the inner edge of the toilet seat along the outer periphery of the center opening. The main body, the bottom wall portion, a peripheral wall portion that is formed so as to substantially coincide with a common virtual plane whose upper edge rises from the outer periphery of the bottom wall portion, and is inserted into the inner wall portion of the toilet seat main body, and the upper edge of the peripheral wall portion A handle that protrudes outward from the outer peripheral surface of the lower peripheral wall portion, and a middle collar that receives the excrement of the infant passing through the central opening.

  According to the present invention, the inner wall of the toilet seat body is provided with the inner wall having the peripheral wall portion that is formed so as to substantially coincide with the common virtual plane and that is inserted into the inner wall portion of the toilet seat body. A part does not get dirty with excrement, and the excrement of an infant falling through the central opening of the toilet seat body can be received in a sanitary manner. And the toilet seat part does not produce a level difference and is comfortable to sit on. In addition, the inner lid can be made smaller than the toilet seat body, and the area of the inside of the inner lid that is contaminated with excrement is reduced, so that washing of the inner lid is reduced. Furthermore, the upper edge of the bag-like disposable sheet can be folded back, and the folded portion can be locked to the upper edge of the inner wall of the inner wall so that the inner surface of the inner wall can be covered with the disposable sheet. In addition, since the upper edge of the peripheral wall portion that rises upward is inserted inside the inner wall portion that hangs downward, the folded portion of the sheet does not turn up. In addition, if the toilet seat body is lifted and the handle is held, the inner lid can be easily taken out and transported.

The toilet main body 12, the toilet seat main body 13, the inner lid 14, and the gold concealment 15 are made of plastic members such as polypropylene and ABS resin, and the infant toilet 11 is an assembly thereof.

  The toilet body 12 has a double structure having a round outer peripheral surface and walls on the outer side and the inner side. The inner wall constitutes a recess. That is, the toilet body 12 has a bottom wall portion 25b at the center thereof, an inner peripheral wall portion 25 rising from the bottom wall portion 25b, and a step 28 that is a toilet seat main body support portion provided near the upper edge of the inner peripheral wall portion 25. . The inner peripheral wall portion 25 becomes a side wall of a concave portion recessed downward, and the bottom wall portion 25b becomes a bottom wall of the concave portion. Further, since the concave portion accommodates the inner collar 14, the inner peripheral wall portion 25 surrounds the inner collar 14, and the bottom wall portion 25b is a flat surface and supports the inner collar from below. The depth of the recess from the upper edge of the toilet main body 12 to the bottom wall portion 25b, that is, the height of the inner peripheral wall portion 25 is substantially the same as the height dimension of the intermediate lid 14. A toilet seat body 14 is detachably attached to the upper part of the toilet body 12. Thereby, the toilet bowl main body 12 supports the toilet seat main body 13 from the downward direction.

  The toilet seat body 13 includes a toilet seat portion 21 that surrounds a central opening S formed at the center of the toilet seat body 13, an inner wall portion 22 that hangs from the inner edge of the toilet seat portion 21 along the outer periphery of the central opening S, and a toilet seat portion. 21 and an outer wall portion 27 depending from the outer edge of 21. The outer wall portion 27 is formed over the entire circumference of the toilet seat body 13 and engages with a step portion 28 formed on the outer periphery of the toilet body 12. The step portion 28 is formed on the outer wall of the toilet body 12 that rises substantially upward, and is an upward flat step having a width substantially the same as the thickness of the outer wall portion 27, and is in contact with the lower edge of the outer wall portion 27. To do. Thus, the toilet seat body 13 is supported so as not to be displaced from the toilet body 12.

  As shown in FIG. 1, the toilet seat 21 is O-shaped in plan view and surrounds the entire circumference of the central opening S. Further, as a modification not shown, the front part of the toilet seat may be cut out in a C shape in plan view. The toilet seat 21 has horizontal planes 21h on both sides in the width direction, has a horizontal plane 21f on the front, and has a common horizontal plane from both sides in the width direction to the front, and the rear part rises above the horizontal plane. That is, a raised portion 26 that is raised upward is formed at the rear portion of the toilet seat portion 21. The raised portion 26 is curved in an arc shape along the outer periphery of the central opening S and extends in the width direction. Then, both end portions in the width direction are smoothly continuous with the horizontal surfaces 21 h on both sides of the toilet seat portion 21. The raised portion 26 is formed in a raised shape at a position away from the central opening S, and the inner edge of the raised portion 26 in contact with the central opening S extends horizontally, the horizontal surface 21 f at the front portion of the toilet seat portion 21, and both sides of the toilet seat portion 21. It is formed at the same height as the horizontal plane 21h of the part.

  When the infant sits down on the infant toilet 11, the horizontal surface 21h of the toilet seat 21 supports the buttocks and thighs of the infant. The raised portion 26 positions the infant's buttocks in the central opening S.

  The inner wall portion 22 is integrally coupled to the toilet seat portion 21 and is provided over the entire circumference of the toilet seat portion inner edge. The inner wall portion 22 is a cylindrical body having both end openings that surround the entire circumference of the central opening S, and is shaped to hang further downward than the outer wall portion 27. As shown in FIG. 3, the intermediate collar 14 is inserted inside the inner wall portion 22.

  A dome portion 23 rising from the inner edge of the toilet seat portion 21 is provided at the front portion of the toilet seat body 13. The dome portion 23 covers the gold concealment 15 described later, and is integrally coupled to the toilet seat portion 21 and the inner wall portion 22. The toilet seat body 13 can be placed alone on the toilet seat of an adult Western-style toilet. At this time, the dome portion 23 functions as a gold concealment.

  The intermediate collar 14 is a container having a bottom wall portion 14a, a peripheral wall portion 14b that rises from the outer periphery of the bottom wall portion 14a, and a handle 24 that protrudes outward from the outer peripheral surface of the peripheral wall portion. Accepts infant excrement passing through 13 central openings S. The bottom wall portion 14a is a flat plate material, and the lower edge of the peripheral wall portion 14b is integrally coupled to the outer edge of the bottom wall portion 14a. The upper edge of the peripheral wall portion 14b protrudes upward in part and is not substantially cut out downward in the other part, but substantially coincides with a common virtual plane. The upper edge of the peripheral wall portion 14 b is inserted from below the toilet seat body 13 into the central opening S that is inside the inner wall portion 22 of the toilet seat body 13.

  The handle 24 protrudes from the outer peripheral surface of the peripheral wall portion below the upper edge of the peripheral wall portion 14b, and has a root portion 24c extending in the horizontal direction, and an upper branch portion 24u branching at the tip of the root portion 24c and extending upward and downward respectively. And the lower branching portion 24d. The upper branch portion 24u and the lower branch portion 24d are one bar-like portion extending in common in the vertical direction. Therefore, the handle 24 has a shape that can be easily gripped by an adult's hand. The handle 24 is integrally coupled to the peripheral wall portion 14b.

  The upper edge of the peripheral wall portion 14b is formed horizontally so as to have a uniform height, and extends along the inner edge of the toilet seat portion 21 while being inserted into the central opening S of the toilet seat body 13. As shown in FIGS. 1 and 3, a slight gap may be interposed between the upper edge of the peripheral wall portion 14 b and the inner edge of the toilet seat portion 21.

  The toilet main body 12 supports the toilet seat main body 13 from below, and accommodates the intermediate lid 14 in the recess of the toilet main body. As a result, the height relationship between the toilet seat body 13 and the middle collar 14 is predetermined, and the upper edge of the peripheral wall portion 14b of the middle collar 14 rising upwards overlaps with the inner wall portion 22 of the toilet seat body 13 hanging downward. The height position of the upper edge of the peripheral wall portion 14b substantially coincides with the height position of the toilet seat portion 21, but strictly speaking, the upper edge of the peripheral wall portion 14b is slightly below the horizontal surfaces 21h and 21f of the toilet seat portion 21. Be placed.

  When the infant sits on the toilet seat 21 and defecates and urinates, the excrement falls, passes through the central opening S of the toilet seat body 13, and is received inside the middle lid 14.

  The gold concealment 15 is a member that is detachably attached to the front of the intermediate collar 14, and has a substantially semicircular shape in a plan view shown in FIG. The lower half portion of the gold concealment 15 includes the lower portion of the gold concealment, has a substantially semicircular cross-sectional shape in plan view, and contacts the outer peripheral surface of the peripheral wall portion 14b. The upper half portion of the gold concealment 15 includes an upper portion of the gold concealment, rises from the upper edge of the peripheral wall portion 14b and the toilet seat portion 21, and covers a front region of the central opening S as it goes upward as shown in FIG. Formed. And the upper half part of the gold concealment 15 which is substantially equal to the shape of the hemisphere divided into two forms a substantially semicircular opening as shown in FIG. When the infant sits across the toilet seat 21 and faces the upper half of the gold concealment 15, the baby's abdomen to buttocks are covered with the gold concealment 15.

  The toilet body 12, the toilet seat body 13, the inner lid 14, and the gold concealment 15 are assembled as shown in FIG. The root portion 24 c of the handle 24 of the intermediate collar 14 comes into contact with the lower edge of the inner wall 22 of the toilet seat body 13.

  Next, an assembly procedure for the infant toilet 11 will be described.

  The infant toilet 11 is assembled in the order shown in the sectional views of FIGS. First, as shown in FIG. 5, a filth treatment sheet 31, which is a bag body having an upper opening and a bottom portion, is placed on the inner side surface of the intermediate collar 14. The waste disposal sheet 31 has the shape shown in the perspective view of FIG. 9, and the upper opening is folded outward as shown in the perspective view of FIG. 10, so that the folded portion 32 covers the upper edge of the peripheral wall portion 14b. Attached to the intermediate collar 14. The waste disposal sheet 31 covers the inner peripheral surface of the peripheral wall portion 14b of the intermediate collar 14 and the upper surface of the bottom wall portion 14a.

  In other words, the waste disposal sheet 31 is made of water-soluble paper. Accordingly, when the excrement of the infant is released on the waste disposal sheet 31 by the use of the infant toilet 11, the middle lid 14 is taken out from the infant toilet 11 by grasping the handle 24 and holding the handle 24. The excrement may be thrown into the adult toilet together with the waste disposal sheet 31.

  As a result, the excrement of the infant can be easily processed by flowing it into an adult flush toilet installed in the house, and the excrement of the infant is not stuck to the middle lid 14, and the washing of the middle lid 14 is reduced. Can do. The infant toilet 11 can be used without a waste disposal sheet.

  The filth treatment sheet 31 is a disposable used only once, and a new clean filth treatment sheet 31 may be put on the inner surface of the middle lid 14 again after the infant toilet 11 is used.

  In the case where the waste disposal sheet 31 is formed of a waterproof film material, the excrement of an infant cannot be processed by flowing it into a flush toilet for adults, but there is an advantage that the intermediate lid 14 can be kept hygienic. .

  Returning to the procedure for assembling the infant toilet 11, the middle lid 14 is then attached with a gold concealment 15 as shown in FIG. The lower edge of the gold concealment 15 comes into contact with the root portion 24 c of the handle 24. Further, a protrusion 15 d extending in the horizontal direction is formed on the inner surface of the gold concealment 15, and the protrusion 15 d engages with the upper edge of the intermediate collar 14. As a result, the gold concealment 15 is attached to the front portion of the intermediate collar 14.

  Next, the inner lid 14 and the gold concealment 15 are accommodated in the recess of the toilet body 12 as shown in FIG. Although not shown in the drawing, positioning means for engaging each other may be provided on the bottom wall portion 14a of the intermediate collar 14 and the bottom wall portion 25b of the recess. As a result, the intermediate collar 14 is easily positioned on the bottom wall portion 25b.

  Next, the toilet seat body 13 is attached to the toilet body 12 as shown in FIG.

  When the toilet seat body 13 is covered from above the toilet body 12, the upper edge of the peripheral wall portion 14 b of the intermediate collar 14 is inserted upward from the lower side of the inner wall portion 22 of the toilet seat body 13 into the inner wall portion 22. Thereby, the folding | returning part 32 of the waste disposal sheet 31 is pushed down by the inner wall part 22, and the folding | returning part 32 is prevented from turning up. Further, the lower edge of the inner wall portion 22 of the toilet seat body 13 is in contact with the upper side of the root portion 24 c of the handle 24. The lower edge of the gold concealment 15 also abuts on the upper side of the root portion 24 c of the handle 24. As a result, the intermediate collar 14 is stably held inside the inner wall portion 22. The lower edge of the inner wall portion 22 and the lower edge of the gold concealment 15 are located in a region surrounded by the upper edge of the peripheral wall portion 14b of the intermediate collar 14, the root portion 24c, and the upper branching portion 24u. By attaching the toilet seat body 13, the intermediate collar 14 is positioned in the central opening S of the toilet seat body 13. Further, the gold concealment 15 is positioned at the front portion of the intermediate collar 14.

  The upper half of the gold concealment 15 is covered by the dome portion 23 of the toilet seat body 13 from the front, and the lower half of the gold concealment 15 is covered by the inner wall portion 22 of the toilet seat main body 13 from the front. The dome part 23 and the inner wall part 22 urge the gold concealment 15 toward the middle collar 14 so that the adhesion between the gold concealment 15 and the middle collar 14 is improved. The fold-back portion 32 of the waste disposal sheet interposed between the gold concealment 15 and the inner casing 14 functions to fill the gap between the gold concealment 15 and the inner casing 14.

  The toilet seat main body 13 and the middle collar 14 supported by the toilet bowl main body 12 are set to a height position such that the upper edge of the peripheral wall portion 14b of the middle collar 14 does not protrude from the toilet seat section 21. In other words, the upper edge of the intermediate collar 14 is at substantially the same height as the horizontal surfaces 21f and 21h of the toilet seat 21 over the entire circumference. And the outer peripheral surface of the surrounding wall part 14b follows the inner peripheral surface of the inner wall part 22 through a clearance gap.

  The folded portion 32 of the filth treatment sheet 31 is sandwiched between the upper edge of the peripheral wall portion 14 b of the middle heel 14 and the inner wall portion 22 of the toilet seat body 13, whereby the filth treatment sheet 31 is fixed to the middle heel 14. Further, the fold-back portion 32 of the waste disposal sheet interposed between the inner wall portion 22 and the intermediate collar 14 functions to fill the gap between the inner wall portion 22 and the peripheral wall portion 14b.

  The assembly of the infant toilet 11 is completed by the procedure described so far. When disassembling the infant toilet 11 in order to dispose of the excrement in the middle lid 14, it is preferable to perform a procedure opposite to the procedure described above.

  By the way, according to the toilet bowl 11 for infants of the present embodiment, the inner collar 14 has the peripheral wall portion 14b inserted into the inner wall portion 22 of the toilet seat body 13, so that the inner wall portion 22 of the toilet seat body 13 is excreted. The excrement of the infant falling through the central opening S of the toilet seat body 13 can be received in a sanitary manner. Moreover, since the inner wall part 22 of the toilet seat body 13 is not soiled with excrement, washing of the toilet seat body 13 is reduced. Further, since the inner collar 14 has a handle 24 that comes into contact with the inner wall portion 22 of the toilet seat body 13, the inner collar 14 is stably held in the central opening S. Furthermore, the handle 24 can be easily taken out of the toilet body 12 by grasping the handle 24, and the handle 14 can be easily and hygienically transported while holding the handle 24. Moreover, the toilet seat body 13 can be used alone by being placed on a Western-style toilet for adults, and can be used as a toilet seat body for infants.

  Further, according to the present embodiment, the upper edge of the peripheral wall portion 14b of the intermediate collar 14 is formed horizontally so as to substantially coincide with a common virtual plane, so that the folded portion 32 of the waste disposal sheet 31 can be easily locked. Can be made.

  And the height position of the upper edge of the peripheral wall part 14b is substantially the same as the height position of the horizontal surfaces 21f and 21h of the toilet seat part 21 in the state in which the peripheral wall part 14b of the inner collar 14 is inserted into the central opening S of the toilet seat body 13. Since it corresponds, the inner wall part 22 of the toilet seat main body 13 is not contaminated with excrement, and the toilet seat main body 13 is kept hygienic. In order to facilitate understanding, the positional relationship between the peripheral wall portion 14b of the intermediate collar 14 and the inner wall portion 22 of the toilet seat body 13 is shown in the longitudinal sectional view of FIG.

  Strictly speaking, the height position of the upper edge of the peripheral wall portion 14b is slightly lower than the height positions of the horizontal surfaces 21f and 21h of the toilet seat portion 21, specifically 2 to 9 mm lower. Thereby, a level difference does not arise in the toilet seat part 21, but sitting comfort for an infant improves.
