Summary of the Invention
Problems to be Solved by the Invention
[0004] It is difficult to cover the entire upper surface of the toilet seat with the toilet seat cover as described above. For this reason, even when the toilet seat cover is attached to the toilet seat, a part of the toilet seat is likely to be exposed without being covered by the toilet seat cover. Depending on the user's posture, the thigh may touch the exposed part of the toilet seat and feel cold, which may deteriorate the usability of the toilet seat. Dirt such as droplets and urine during local cleaning may adhere to the toilet seat cover part, resulting in unsanitary conditions and may deteriorate the usability of the toilet seat. Also, during sweating in summer, when sitting down, one may feel an unpleasant stickiness on the toilet seat cover, which may deteriorate the usability of the toilet seat.
[0005] The present disclosure has been completed based on the above circumstances, and an object thereof is to provide a toilet seat cover that can improve the usability of a toilet seat.
Means for Solving the Problems
[0006] The toilet seat cover of the present disclosure is a toilet seat cover that is detachably attached to the upper surface of a toilet seat, and includes an annular main body, at least one of a protruding portion that protrudes inward along the inner peripheral edge of the main body, and a protruding portion that protrudes outward along the outer peripheral edge of the main body.

Modes for Carrying Out the Invention
[0008] [1] The toilet seat cover of the present disclosure is a toilet seat cover that is detachably attached to the upper surface of a toilet seat, and includes an annular main body portion, an overhanging portion that projects inward along the inner peripheral edge of the main body portion, and at least one of an overhanging portion that projects outward along the outer peripheral edge of the main body portion. According to such a configuration, the overhanging portion can make it difficult for the user's thighs or the like to hit the toilet seat and difficult for dirt to adhere, thereby improving the usability of the toilet seat. [2] In the toilet seat cover described in [1] above, the main body portion and the overhanging portion may be made of a self-expanded resin. According to such a configuration, liquid dirt such as urine does not soak into the toilet seat cover, and it can be used hygienically by wiping it with a cleaning sheet or the like in the same manner as a normal hard resin toilet seat. Also, by forming smooth-shaped irregularities on the surface of the self-expanded resin, the seated user is less likely to feel sticky. Therefore, the usability of the toilet seat can be improved. [3] In the toilet seat cover described in [1] or [2] above, the main body portion and the overhanging portion may have elasticity. According to such a configuration, the toilet seat cover can be expanded and contracted according to a toilet seat with slightly different dimensions to cover the upper surface of the toilet seat. Therefore, even in the case of toilet seats with slightly different dimensions, the exposed portion on the upper surface can be reduced, and the usability of the toilet seat can be improved. [4] In the toilet seat cover described in any one of [1] to [3] above, a suction cup portion formed on the main body portion itself may be provided on the back surface of the main body portion. According to such a configuration, the expanded and contracted toilet seat cover can be attached to the upper surface of the toilet seat by the suction cup portion. The toilet seat cover can be easily removed by hooking a finger on the overhanging portion. Since the toilet seat cover is composed of a single material, it does not need to be separated and can be easily recycled. [5] In the toilet seat cover according to any one of [1] to [3] above, it may have an adsorption sheet joined to the back surface of the main body portion, and the adsorption sheet may be divided and arranged at a plurality of locations on the back surface of the main body portion. According to such a configuration, the toilet seat cover in the stretched or contracted state can be attached to the upper surface of the toilet seat by the adsorption sheet. A finger can be hooked on the protruding portion to easily remove the toilet seat cover. When a single adsorption sheet is joined to the entire back surface of the main body portion, the adsorption sheet may interfere with the expansion and contraction of the main body portion. However, since the adsorption sheet is divided and arranged at a plurality of locations, it can be made less likely to interfere with the expansion and contraction of the main body portion.
[0009] <Embodiment 1> The toilet seat cover 10 in the present embodiment is detachably attached to the upper surface 51 of the toilet seat 50 as shown in FIG. 1. The toilet seat 50 is provided in the toilet seat device 60. The toilet seat device 60 includes a toilet seat 50, a toilet lid 61, and a support portion 62. The toilet seat device 60 is provided in the washlet toilet 63. The washlet toilet 63 includes a toilet body 64 and a toilet seat device 60. The toilet body 64 is made of ceramics and has a toilet bowl portion 65.
[0010] Hereinafter, in each component, the X-axis direction is described as forward, the Z-axis direction is described as upward, and the Y-axis direction is described as leftward. The side of the toilet body 64 where the toilet bowl portion 65 is provided is the front side, and the side where the toilet seat device 60 is attached is the rear side. The Z-axis extends in the vertical direction.
[0011] The toilet seat 50 is made of a hard resin. The toilet seat 50 includes a toilet seat front portion 52, a toilet seat rear portion 53, and left and right toilet seat side portions 54, and a toilet seat opening 55 is formed at the center. The shape of the toilet seat opening 55 is an oval shape that tapers forward in a plan view. Since the toilet seat 50 does not have a heater, when the toilet seat cover 10 is not installed, a person sitting on it is likely to feel cold.
[0012] The support portion 62 rotatably supports the toilet seat 50 and the toilet lid 61 in a fallen state and a standing state, respectively. The fallen state is a state of lying down along the upper surface of the toilet body 64. The standing state is a state of rising upward from the upper surface of the toilet body 64.
[0013] As shown in FIG. 2, the toilet seat cover 10 includes a front portion 11, a rear portion 12, and left and right side portions 13, and forms an annular shape with an opening 14 formed at the center. The front portion 11 covers the upper surface side of the front portion 52 of the toilet seat. The left and right side portions 13 cover the upper surface sides of the left and right side portions 54 of the toilet seat. The rear portion 12 covers the upper surface side of the rear portion 53 of the toilet seat.

The main body portion 24 includes an upper surface portion 15, an inner surface portion 16, and an outer surface portion 17, and covers the upper surface 51 of the toilet seat 50. The inner surface portion 16 and the outer surface portion 17 function to suppress displacement with respect to the toilet seat 50 when the toilet seat cover 10 is attached to the toilet seat 50.
[0015] The upper surface portion 15 forms an annular shape continuously with the front portion 11, the rear portion 12, and the left and right side portions 13. The thickness dimension of the upper surface portion 15 is substantially constant. The inner surface portion 16 is bent downward from the inner peripheral edge of the upper surface portion 15. The inner surface portion 16 is provided on the entire circumference of the opening 14. The thickness dimension of the inner surface portion 16 gradually decreases from the inner peripheral edge of the upper surface portion 15 toward the lower end. The inner surface portion 16 covers the curved portion of the inner peripheral side corner of the upper surface 51 of the toilet seat 50. The lower end of the inner surface portion 16 of the rear portion 12 gently slopes downward from the center in the left-right direction toward both end sides as shown in FIG. 6.
[0016] The outer surface portion 17 bends downward from the outer peripheral edge of the upper surface portion 15. The outer surface portion 17 is provided on the front portion 11 and the left and right side portions 13, and is not provided on the rear portion 12. The thickness dimension of the outer surface portion 17 gradually decreases from the outer peripheral edge of the upper surface portion 15 toward the lower end. The outer surface portion 17 covers the curved portions at the corners on the outer peripheral side of the upper surface 51 of the toilet seat front portion 52 and the left and right toilet seat side portions 54. As shown in FIG. 7, the lower end of the outer surface portion 17 is located above the lower end of the inner surface portion 16.
[0017] As shown in FIG. 2, the inner protruding portion 18 protrudes inward along the inner peripheral edge of the main body portion 24 and is continuous around the entire circumference. The outer protruding portion 19 protrudes outward along the outer peripheral edge of the main body portion 24 and is continuous around the entire circumference.
[0018] As shown in FIGS. 3 and 4, the inner protruding portion 18 is provided on the inner surface portion 16. The inner protruding portion 18 is thinner than the inner surface portion 16. The inner protruding portion 18 protrudes inward from a position slightly above the lower end of the inner surface portion 16. The protruding dimension of the inner protruding portion 18 from the inner surface portion 16 is preferably 1.5 mm or more.
[0019] In the front portion 11 and the left and right side portions 13, the outer protruding portion 19 is provided at the lower end portion of the outer surface portion 17. The outer protruding portions 19 in the front portion 11 and the left and right side portions 13 protrude outward from a position slightly above the lower end of the outer surface portion 17. The outer protruding portion 19 in the rear portion 12 protrudes rearward obliquely upward from the rear end portion of the rear portion 12. The outer protruding portion 19 is thinner than the outer surface portion 17. The protruding dimensions of the outer protruding portion 19 from the outer surface portion 17 and the rear portion 12 are preferably 1.5 mm or more. When removing the toilet seat cover 10 from the toilet seat 50, it can be easily removed by hooking a fingertip on the outer protruding portion 19.
[0020] The toilet seat cover 10 is made of a material that is softer than the toilet seat 50 and has elasticity. The toilet seat cover 10 has a predetermined cushioning property and elasticity. The toilet seat cover 10 can be easily stretched and fitted precisely to the main body 24, the inner projecting portion 18, and the outer projecting portion 19 with respect to toilet seats 50 of slightly different dimensions. The toilet seat cover 10 can easily cover the entire upper surface 51 of toilet seats 50 of slightly different dimensions.
[0021] The toilet seat cover 10 is made of a closed-cell foamed resin with low heat flux. Thus, a person sitting on the toilet seat cover 10 is less likely to feel cold. As the material of the toilet seat cover 10, it is advisable to use low heat flux materials such as closed-cell polyethylene (PE), ethylene-vinyl acetate copolymer (EVA), and foamed polypropylene. The foaming ratio of the resin foam constituting the toilet seat cover 10 may be about 30 times. The toilet seat cover 10 is preferably shaped by a manufacturing method such as thermocompression molding, cold pressing, or vacuum molding, cooled and solidified, and then taken out and punched by a Thomson type.
[0022] The toilet seat cover 10 includes a seating surface 21 and an attachment surface 22. The seating surface 21 is the upper surface of the main body 24 in a state of being attached to the reclined toilet seat 50. The attachment surface 22 is the lower surface of the main body 24 in a state of being attached to the reclined toilet seat 50 and is in close contact with the toilet seat 50.
[0023] As shown in FIGS. 3 and 4, the seating surface 21 slopes downward from the outer peripheral side to the inner peripheral side of the upper surface portion 15. As shown in FIG. 5, the seating surface 21 of the front portion 11 gently slopes downward from the left and right side portions 13 toward the center in the left-right direction in a front view. As shown in FIG. 7, the seating surface 21 of the left and right side portions 13 slopes downward from the rear side to the front side.
[0024] The seating surface 21 may be formed with gentle irregularities. The gentle irregularities may have the shape as shown in FIGS. 10 and 11. By forming gentle irregularities on the seating surface 21, it is possible to make it difficult for a person sitting on it to feel stickiness due to sweating in seasons such as summer when sweating easily occurs. The gentle irregularities can also be easily cleaned with a cleaning sheet or the like even when dirt such as urine adheres to the seating surface 21. The gentle irregularities on the seating surface 21 may be formed using a mold with dimples or embossments.
[0025] As shown in FIGS. 3 and 4, the mounting surface 22 is composed of the back surfaces of the upper surface portion 15, the inner surface portion 16, and the outer surface portion 17. The mounting surface 22 has a three-dimensional shape substantially the same as the upper surface 51 of the toilet seat 50. The mounting surface 22 is in close contact with the upper surface 51 of the toilet seat 50 and fits exactly to the upper surface 51 of the toilet seat 50.
[0026] An ultrathin skin layer may be formed on the mounting surface 22. The ultrathin skin layer may be a dense surface formed on the surface of the toilet seat cover 10 itself. The dense surface may be formed by thermocompression molding with the heating temperature of the mounting surface 22 being higher than the heating temperature of the seating surface 21 when molding the toilet seat cover 10.
[0027] The ultrathin skin layer may be a stain-preventing film joined to the mounting surface 22. As the stain-preventing film, a film made of polyethylene or the like may be used. The stain-preventing film may be joined to the mounting surface 22 by closely adhering the stain-preventing film to the mold for molding the toilet seat cover 10, putting the molding material of the toilet seat cover 10 into the cavity of the mold, and applying pressure and heat. As a method of joining the stain-preventing film to the mounting surface 22, ultrasonic welding, pressure-air forming, vacuum forming, etc. may be adopted. Also, a manufacturing method of pre-attaching it to the independent foamed resin sheet before shaping may be used.
[0028] According to the embodiment configured as described above, the following effects can be achieved. The toilet seat cover 10 is detachably attached to the upper surface 51 of the toilet seat 50. The toilet seat cover 10 includes a main body portion 24, an inner overhanging portion 18, and an outer overhanging portion 19. The main body portion 24 has an annular shape. The inner overhanging portion 18 projects inward along the inner peripheral edge of the main body portion 24. The outer overhanging portion 19 projects outward along the outer peripheral edge of the main body portion 24. According to this configuration, the inner overhanging portion 18 and the outer overhanging portion 19 can make it difficult for the user's thighs or the like to hit the toilet seat 50 and difficult for dirt to adhere, so that the usability of the toilet seat 50 can be improved.
[0029] The main body portion 24, the inner overhanging portion 18, and the outer overhanging portion 19 are made of independently foamed resin. According to such a configuration, liquid dirt such as urine does not soak into the toilet seat cover 10, and it can be hygienically used by wiping it with a cleaning sheet or the like in the same manner as a normal hard resin toilet seat. In addition, since smooth-shaped irregularities are formed on the surface of the toilet seat cover 10, the seated user is less likely to feel sticky. Therefore, the usability of the toilet seat 50 can be improved.
[0030] The main body portion 24, the inner overhanging portion 18, and the outer overhanging portion 19 have elasticity. According to this configuration, the toilet seat cover 10 can be expanded and contracted according to the toilet seat 50 of different dimensions to cover the upper surface 51 of the toilet seat 50. Therefore, the exposed portion of the upper surface 51 of the toilet seat 50 with slightly different dimensions can be reduced, and the usability of the toilet seat 50 can be improved.
[0031] <Embodiment 2> Next, the toilet seat cover 10 according to Embodiment 2 embodying the present disclosure will be described with reference to FIG. 8. The toilet seat cover 10 of the present embodiment is different from Embodiment 1 in that a suction cup portion 25 is provided on the mounting surface 22. In addition, the same components as those in Embodiment 1 are denoted by the same reference numerals, and redundant descriptions are omitted.
[0032] The suction cup portions 25 are provided in plurality on the mounting surface 22. The suction cup portions 25 are evenly arranged over the entire front portion 11, rear portion 12, and left and right side portions 13. Each suction cup portion 25 is circular when viewed from below. Each suction cup portion 25 has a dish shape with a concave center portion. The radial dimensions of the suction cup portions 25 vary in size. The suction cup portions 25 are formed on the main body portion 24 itself. When the mounting surface 22 is pressed against the upper surface 51 of the toilet seat 50, the inside of each suction cup portion 25 becomes in a state of low air pressure, and each suction cup portion 25 adheres to the upper surface 51 of the toilet seat 50. Thereby, the toilet seat cover 10 is held in a state of being expanded and contracted according to the shape of the toilet seat 50.
[0033] As described above, in the present embodiment, the suction cup portions 25 formed on the main body portion 24 itself are provided on the back surface of the main body portion 24. According to this configuration, the expandable and contractible toilet seat cover 10 can be attached to the upper surface 51 of the toilet seat 50 by the suction cup portions 25. The toilet seat cover 10 can be easily peeled off by hooking a finger on the outer overhanging portion 19. Since the toilet seat cover 10 is composed of a single material, it does not need to be separated and can be easily recycled.
[0034] <Embodiment 3> Next, the toilet seat cover 10 according to Embodiment 3 embodying the present disclosure will be described with reference to FIG. 9. The toilet seat cover 10 of the present embodiment is different from Embodiment 1 in that a suction sheet 26 is provided on the mounting surface 22. In addition, the same components as those in Embodiment 1 are denoted by the same reference numerals and redundant descriptions are omitted.
[0035] The suction sheets 26 are arranged in 11 sheets on the mounting surface 22. Each suction sheet 26 is joined to the mounting surface 22. A plurality of suction sheets 26 are arranged in each of the front portion 11, the rear portion 12, and the left and right side portions 13. Each suction sheet 26 has a shape curved along the opening 14 when viewed from below. The suction sheet 26 may have, for example, an acrylic resin-based adhesive layer on one side of a base material and suction micropores on the surface that contacts the toilet seat 50. The suction sheet 26 has a suction surface that can be repeatedly attached to and detached from the toilet seat 50. When the mounting surface 22 is pressed against the upper surface 51 of the toilet seat 50, the suction surface of each suction sheet 26 adheres to the upper surface 51 of the toilet seat 50.
[0036] As described above, in this embodiment, the toilet seat cover 10 has the suction sheets 26 joined to the back surface of the main body portion 24. The suction sheets 26 are divided and arranged at 11 locations on the back surface of the main body portion 24. According to this configuration, the toilet seat cover 10 in the expanded and contracted state can be attached to the upper surface 51 of the toilet seat 50 by the suction sheets 26. By hooking a finger on the outer projecting portion 19, the toilet seat cover 10 can be easily removed. If a single suction sheet is joined to the entire back surface of the main body portion 24, the suction sheet may interfere with the expansion and contraction of the main body portion 24. However, since the suction sheets 26 are divided and arranged at 11 locations, it is possible to make it difficult to interfere with the expansion and contraction of the main body portion 24.
