The mold 19 includes an annular space 21 for allowing resin to flow into the periphery of the plate body 13 and the lid body 15 . By flowing molten resin into the space 21 from a gate (not shown) of the mold 19, the bathtub cover 11 with the trim shown in FIG. 5 can be manufactured.

Next, the effects of the second embodiment will be described.

In the second embodiment, the work of attaching the trim 17 to the plate body 13 using adhesives, fasteners, etc. is not required, and the manufacturing work becomes easy. Cost reduction, especially in mass production, can thus be achieved. The plate main body 13 and the trim 17 are in close contact with each other by suppressing the occurrence of gaps at the boundary portions between them, so that the appearance quality is improved, and the reliability as a product is improved.

The plate body 13 of the second embodiment is made of resin, and the resin plate body 13 includes a pair of plate portions 13a that are spaced apart from each other and arranged to face each other, and a connecting portion 13b that connects the pair of plate portions 13a to each other. Therefore, the plate body 13 can ensure the strength in the direction of connecting the pair of plate parts 13a to each other by the connection part 13b, and the reliability as the bathtub cover 11 can be improved.

The connecting portion 13b of the second embodiment extends in the X direction along the surface of the pair of plate portions 13a across one end portion and the other end portion, and intersects the X direction along the surface of the pair of plate portions 13a In the Y direction, a plurality of are provided at intervals, so that hollow portions 13c are formed therebetween. Since the plate body 13 is provided with the hollow portion 13c, it is possible to reduce the weight while maintaining the strength, and to improve the thermal insulation performance of the bathtub cover 11.

In the second embodiment, a lid 15 for closing the opening 13c1 is attached to the opening 13c1 of the hollow portion 13c at one end and the other end in the extending direction of the connecting portion 13b. Thereby, when the trim 17 is integrally molded with resin with respect to the peripheral edge of the plate body 13, the resin can be suppressed from flowing into the hollow portion 13c.

The cover 15 of the second embodiment includes a plurality of fitting portions 15a that can be individually fitted into the plurality of openings 13c1, and a head portion 15b that connects the ends of the plurality of fitting portions 15a protruding from the opening 13c1 to each other.

Therefore, the cover body 15 is not exposed to the outside, and the appearance quality is further improved. Since the plate body 13 is made of resin, it is made of transparent resin, and the state in the bathtub can be checked through the plate body 13 without opening the bathtub cover 11 during use, which improves convenience.

[Variation of the second embodiment]

Next, a modification of the second embodiment will be shown. The bathtub cover of the modification is the same as the bathtub cover 11 of FIG. 5 in appearance. FIGS. 13A to 13C show the state before molding the resin-made trim 17 shown in FIG. 5 , but for convenience, the bathtub cover 110 is used for description.

The bathtub cover 110 uses the same resin-made plate body 13 as the bathtub cover 11 of the second embodiment. The biggest difference between the bathtub cover 110 and the bathtub cover 11 is that the cover body 16 for recessed parts shown in FIG. 13D is attached to the recessed part 13d of the plate body 13 shown in FIG. 6 .

The cover body 16 for the concave portion is as shown in Fig. 13B and Fig. 13D As shown, it is provided with the fitting part 16a which can be fitted into the recessed part 13d; The insertion portion 16a corresponds to the elongated cube-shaped recessed portion 13d, has a substantially cube-shaped outer shape, and is in close contact with the inner surface of the recessed portion 13d in a state of being inserted into the recessed portion 13d.

The inside of the fitting part 16a is hollow, and the front end on the opposite side to the head part 16b is open. A plurality of ribs 18 for securing rigidity are provided at substantially equal intervals along the longitudinal direction inside the fitting portion 16a. A curved surface 16a1 is formed on the outer peripheral edge of the front end on the opening side of the insertion portion 16a so as to be inserted into the recessed portion 13d. Instead of the curved surface 16a1, an inclined surface may be used.

The length of the longitudinal direction of the head part 16b (corresponding to the X direction of the plate body 13) is substantially equal to the length of the pair of plate parts 13a in the X direction. The head portion 16b includes: an end surface portion 16b1 for sealing the proximal end side of the hollow portion of the insertion portion 16a; A pair of flanges 16b2.

The flange portion 16b2 protrudes from the end surface portion 16b1 shorter than the insertion portion 16a protrudes from the end surface portion 16b1, and covers the surface of the plate portion 13a near the opening of the recess 13d of the plate body 13. A flange portion gap 16d is formed between the flange portion 16b2 and the fitting portion 16a. When the cover body 16 for recessed parts is attached to the plate body 13, the protrusion 13a1 of the plate body 13 enters the flange gap 16d. The length in the longitudinal direction (corresponding to the X direction in FIG. 6 ) of the fitting portion 16a is shorter than the length in the longitudinal direction of the flange portion 16b2. Therefore, the cover body 16 for recessed parts and the cover body 15A described later are installed. When mounted on the plate main body 13, the interference of the embedded portion 16a and the embedded portion 15a is avoided.

Fig. 13E is a plan view of the periphery of the longitudinal end portion of the lid body 15A for sealing the hollow portion 13c shown in Fig. 6 , and the lid body 16 for recessed portion is shown by a two-dot chain line. Fig. 13F is a J-direction view of Fig. 13E. The overall shape of the lid body 15A is substantially the same as that of the lid body 15 of the second embodiment shown in FIGS. 7 and 8 , but as shown in FIG. 13E , the shape of the end in the longitudinal direction is different.

The longitudinal end portion of the lid body 15A includes an arcuate surface 15e in which the outer peripheral surface of the head portion 15b forms an arcuate shape, and a planar contact surface 15f curved from the end of the arcuate surface 15e toward the fitting portion 15a.
