The bath lid 100 is placed on the upper part of the bathtub 110, and keeps the hot water stored in the bathtub 110 together with another bath lid (not shown). The bath lid 100 is used as a substitute for a table when the user sits down or keeps the user immersed in the bathtub 110 in addition to keeping the water warm.

  The bathtub 110 has a bathtub main body 111 for storing hot water, and a flange step 114 which is one step lower than the flange 112 is provided circumferentially below the inner peripheral edge of the upper flange 112. The flange step portion 114 has the flat portion 34 and has a slope that becomes lower at the inner peripheral edge by an angle greater than 0 degrees and 3 degrees or less from the horizontal plane 4 (see FIG. 5).

  Bath lid 100 is placed on flange step 114 of bathtub 110. The bath lid 100 is at substantially the same height as the counter 116 provided in the washing room, and the user transfers between the bath lid 100 and the counter 116 in a state where the bath lid 100 is positioned close to the longitudinal end 115 of the bathtub 110. Suitable to work.

  The bath lid 100 includes a lid body 1 having a rectangular plate shape, and a peripheral portion 2 of the lid body 1 contacts the flat portion 34 of the flange step 114 of the bathtub 110. The lid body 1 has a core material 11, surface materials 12 and 13, and a cushion material. The core material 11 is made of a foamed resin such as expanded polystyrene, and has a rectangular plate shape having an appropriate thickness in order to enhance the heat retention of the hot water stored in the bathtub 110. The surface material 12 is a thin plate of fiber reinforced resin (FRP) in which glass fiber is impregnated with a synthetic resin, and covers one surface side of the core material 11 in the thickness direction. The surface material 13 is formed by attaching a polypropylene sheet as a protective film to the surface of a thin plate of fiber reinforced resin (FRP) in which glass fiber is impregnated with a synthetic resin, and covers the other surface of the core material 11 in the thickness direction. The polypropylene sheet is subjected to, for example, leather grain surface treatment to enhance the design.

  The cushion material 14 is made of a foamed resin such as foamed polyethylene, and is provided so as to cover one surface side of the core material 11. The cushion member 14 has, at the edge, a raised portion 14a along one long side and a raised portion 14b along two short sides. The ridges 14a and 14b are continuous. The cushion material 14 does not have a raised portion at the edge of the long side opposite to the long side provided with the raised portion 14a. The bump on the surface of the cushion member 14 has a C-shape as a whole. The raised portions 14a and 14b visually indicate the direction of seating and improve the comfort of the user. In addition, the cushion material 14 is subjected to, for example, leather grain surface treatment to enhance the design.

  The peripheral portion 2 includes a covering portion 21 extending along two short sides of the bath lid 100, a covering portion 22 extending along one long side of the bath cover 100, and a long side facing the long side. It has a covering portion 23 that extends.

  FIG. 5 is a cross-sectional view of a portion X in the peripheral portion 2 of the bath lid 100 of FIG. Hereinafter, the portion of the peripheral portion 2 having the covering portion 21 on one short side will be described, but the portion of the peripheral portion 2 having the covering portion 21 on the other short side, and the peripheral portion having the covering portions 22 and 23. The same configuration can be applied to the second part, and the description of these parts is omitted for simplification of description.

  The covering part 21 has a first part 21a, a second part 21b, and an end face covering part 21c. The end surface covering portion 21 c has a plate shape having a width in the thickness direction of the lid main body 1 and extending along the short side of the lid main body 1, and covers the outer peripheral end surface of the lid main body 1.

  The first portion 21a is bent inward from the one end of the lid body 1 in the thickness direction of the lid body 1 in the end face covering portion 21c, has a plate shape extending along the short side of the lid body 1, and has a cushion. The edge of the surface of the material 14 is covered. Further, the second portion 21b is bent inward from the other end of the lid body 1 in the thickness direction of the lid body 1 in the end face covering portion 21c, and has a plate shape extending along the short side of the lid body 1; The edge of the surface material 13 is covered. In the cross section shown in FIG. 5, the dimension from the base end to the distal end connected to one end of the end surface covering portion 21c in the first portion 21a is from the base end to the distal end connected to the other end of the end surface covering portion 21c in the second portion 21b. Larger than the dimension to the part.

  In the covering portion 21, a flat surface 21d is formed on an outer surface on one side of the first portion 21a on which the cushion material 14 of the lid main body 1 is provided. The flat surface 21d is inclined so that the center side of the lid main body 1 projects to one side of the lid main body 1 on which the cushion material 14 is provided. The flat surface 21d shown in FIG. 5 is represented so that the angle of inclination is larger than the flat portion 34 of the flange step 114. For this reason, the first portion 21a comes into contact with the flat portion 34 at the tip end, and a slight gap 31 is generated between the flat surface 21d and the flange step portion 114. However, the inclination angle of the flat surface 21d is flattened. By making the inclination angle of the portion 34 the same, the surfaces come into contact with each other, and the gap 31 is eliminated.

  The first portion 21a, the second portion 21b, and the end surface covering portion 21c of the covering portion 21 are made of, for example, an olefin-based elastomer, and have a hardness according to the use of each portion depending on the amount of the contained polypropylene. The hardness of the first portion 21a is higher than the hardness of the second portion 21b. Specifically, the first portion 21a has a Shore A hardness of 90 or more according to JIS K6253, and the second portion 21b has a Shore A hardness of 80 or more and less than 90 according to JIS K6253. The hardness of the end surface covering portion 21c is the same as the hardness of the first portion 21a.

  The first portion 21a, the second portion 21b, and the end surface covering portion 21c of the covering portion 21 may be integrally formed by extrusion or injection, or may be formed separately from each other and adhered with an adhesive. Further, the partially combined molded products may be bonded with an adhesive.

  Next, the operation of bath lid 100 and bathtub device 120 will be described. When the user sits on the bath lid 100 and uses it, the bath lid 100 is placed on the flange step 114 of the bathtub 110 with the cushioning material 14 side up. When the user sits on the bath lid 100, the cushioning material 14 supports the weight with an appropriate repulsive force, and enables a long-time sitting. In addition, since the lid body 1 covers both surfaces in the thickness direction of the core material 11 with the surface materials 12 and 13 made of fiber reinforced resin, the lid body 1 has high strength and can bear the weight of the user.

  As described above, the raised portions 14a and 14b of the cushion material 14 have a C-shape as a whole, and visually indicate the direction of seating. That is, the raised portions 14a and 14b give the user an impression that the user can easily sit by sitting with the raised portion 14a on the back side. When the user sits with the raised portion 14a on the back side, the thigh is located along the edge on the long side of the cushion material 14 without the raised portion, and is easy to sit.

  In the covering portion 21 of the peripheral portion, the dimension from the base end portion connected to one end of the end surface covering portion 21c in the first portion 21a to the distal end portion is from the base end portion connected to the other end of the end surface covering portion 21c in the second portion 21b. It is larger than the dimension up to the tip. Thus, the first portion 21a is suitable for preventing the cushion material 14 from being turned up.

  When used as a table, bath lid 100 is placed on flange step 114 of bathtub 110 with surface material 13 side up. As shown in FIG. 5, in the bath lid 100, the first member 21 a of the covering portion 21 in the peripheral portion 2 comes into contact with the flange step 114. Since the first member 21a is higher in hardness than the second member 21b, the surface is hardly deformed when the bath lid 100 is placed on the flange step 114, and easily slides in a direction along the surface of the flange step 114. . The bath lid 100 is easy to slide on the flange step 114, so that when the user uses it as a table, the bath lid 100 can be easily brought closer to or away from the user, which is convenient.

  Further, bath lid 100 blocks the opening of the upper surface of bathtub 110 together with other bath lids, and keeps the hot water stored in bathtub body 111 warm. Although both sides of the bath lid 100 may be placed on the upper side, a case where the cushion material 14 is used with the cushion member 14 facing downward will be described below. When the flat surface 21d of the first member 21a in the covering portion 21 of the peripheral portion 2 and the flat portion 34 of the flange step 114 are in close contact with each other, the heat retention of the hot water stored in the bathtub main body 111 is enhanced. As shown in FIG. 5, when the inclination angle of the flat surface 21 d is different from that of the flat portion 34, a slight gap 31 is generated. However, since the water is accumulated in the gap 31, the airtightness is enhanced, and the hot water stored in the bathtub main body 111 is increased. The heat retention becomes higher.

  In the gap 31, water vapor in the bathroom condenses and becomes water droplets at the flange portion 112 and the like, and descends to the flange step portion 114, where water accumulates. In addition, water vapor generated from the hot water stored in the bathtub main body 111 leaks to the outside, that is, the gap 31 side from a slight gap between the tip portion of the first portion 21a and the contact portion between the flange step 114 and condenses. It becomes water and accumulates in the gap 31. Since tension is generated in water on both surfaces of the flat surface 21 d and the flange step 114, water easily accumulates in the gap 31. The accumulation of water in the gap 31 enhances the tightness between the bath lid 100 and the flange step 114, and makes it difficult for water vapor generated from the hot water stored in the bathtub body 111 to leak to the outside. The warmth of hot water increases. Further, since the upper part of the gap 31 is covered with the core material 11 having heat insulation, heat hardly escapes upward from the flange step portion 114, and heat insulation is enhanced.

  The flat surface 21d is inclined so that the center side of the lid main body 1 projects toward one surface of the lid main body 1 on which the cushion material 14 is provided. Even when the bath lid 100 has a shape that protrudes toward one surface side of the lid main body 1 at the peripheral portion 2 of the lid main body 1, the sealing performance with the flange step 114 can be enhanced by the flat surface 21d. In addition, the heat retention of the hot water stored in the bathtub body 111 is improved.

  The raised portion 14b of the cushion material 14 forms an outer surface on the center side of the lid main body 1 that is continuous with the flat surface 21d. The center of the lid body 1 with respect to the edge of the raised portion 14 b projects toward one surface side of the lid body 1. The raised portion 14 b has a protruding portion abutting against the inner peripheral edge of the flange step 114, thereby restricting the movement of the bath lid 100 in the horizontal direction and increasing the tightness of the bath lid 100 and the flange step 114. The flat surface 21 d may be formed so as to extend further from the inner peripheral edge of the flange step 114 to the center side of the lid main body 1. Since the flat surface 21d is formed so as to protrude toward one surface at the center side of the lid main body 1, the bath lid 100 restricts horizontal movement, and the tightness of the bath lid 100 and the flange step 114 is improved. Enhance.

  By setting the hardness of the first portion 21a in the covering portion 21 of the peripheral portion 2 to 90 or more in Shore A hardness according to JIS K6253, the bath lid 100 can easily slide on the flange step portion 114. Furthermore, the surface of the first portion 21a is unlikely to be damaged when the fingernail or the like hits it, thereby preventing the cushion material 14 from being turned up. By setting the hardness of the end surface covering portion 21c to be the same as the hardness of the first portion 21a, the surface of the end covering portion 21c is hardly damaged when a fingernail or the like hits the end surface covering portion 21c. Scratch is less likely to occur at the part in contact with the other party.

  Further, the second portion 21b has a Shore A hardness of 80 or more and less than 90 according to JIS K6253, so that the bath lid 100 is less likely to slip at the flange step 114. By setting the second portion 21b to have a Shore A hardness of 80 or more, wear caused by rubbing with the flange step portion 114 and deterioration of the material caused by corrosion are prevented.

  FIG. 6 is a cross-sectional view similar to FIG. 5 of the peripheral portion 2 of the bath lid 100 according to the modification. In the bath lid 100 according to this modified example, the flat surface 21d of the covering portion 21 in the peripheral portion 2 is parallel to the flat portion 34 of the flange step portion 114 and is in surface contact therewith. The flat surface 21d is such that when the bath lid 100 is placed on the flange step 114, the first portion 21a is deformed by its own weight of the bath lid 100, and is in parallel with the flat portion 34 of the flange step 114 to make surface contact. It may be.

  The bath lid 100 has a flat surface 21d that comes into surface contact with the flat portion 34 of the flange step 114, so that the adhesion is enhanced and the heat retention of the hot water stored in the bathtub body 111 is increased. In addition, since the upper part of the flange step 114 is covered with the core material 11 having heat insulation, heat hardly escapes upward from the flange step 114, and the heat insulation is enhanced.

  FIG. 7 is a cross-sectional view similar to FIG. 5 of a peripheral portion 2 of a bath lid 100 according to another modification. In the bath lid 100 according to this modification, the covering portion 21 in the peripheral portion 2 covers the outer peripheral end surface of the cushion material 14, but does not cover the edge of the surface of the cushion material 14. The flat surface 14 d is formed on the outer surface of the peripheral portion of the cushion material 14 in the peripheral portion 2 of the lid body 1. The flat surface 14d is inclined so that the center side of the lid main body 1 projects to one surface side of the lid main body 1 on which the cushion material 14 is provided. The flat surface 14d shown in FIG. 7 is shown such that the inclination angle is larger than the flat portion 34 of the flange step 114. Therefore, a slight gap 31 is generated between the flat surface 14d and the flange step 114. However, by making the inclination angle of the flat surface 21d the same as the inclination angle of the flat portion 34, the surfaces contact each other. Then, the gap 31 is eliminated.

  The close contact between the flat surface 14d and the flat portion 34 of the flange step 114 enhances the heat retention of the hot water stored in the bathtub body 111. As shown in FIG. 7, when the inclination angle of the flat surface 14 d is different from that of the flat portion 34, a slight gap 31 is generated. However, the water is accumulated in the gap 31 to enhance the hermeticity, and the hot water stored in the bathtub main body 111. The heat retention becomes higher. In the gap 31, water vapor in the bathroom condenses and becomes water droplets at the flange portion 112 and the like, and descends to the flange step portion 114, where water accumulates. In addition, water vapor generated from the hot water stored in the bathtub main body 111 leaks to the outside, that is, the gap 31 side from a slight gap in a contact portion between the cushion material 14 and the flange step portion 114, and condenses into water, Collected in the gap 31. Since tension is generated in the water on both surfaces of the flat surface 14 d and the flange step 114, the water easily accumulates in the gap 31. The accumulation of water in the gap 31 increases the tightness between the bath lid 100 and the flange step 114, and enhances the heat retention of the hot water stored in the bathtub body 111.

  Further, since the upper part of the gap 31 is covered with the core material 11 having heat insulation, heat hardly escapes upward from the flange step portion 114, and heat insulation is enhanced.
