By pouring molten resin into the space 21 from a gate (not shown) of the mold 19, the bath lid 11 with a decorative edge shown in FIG. 5 can be manufactured.

Next, the function and effect of the second embodiment will be described.

The second embodiment does not require the work of attaching the decorative edge 17 to the board body 13 with an adhesive, a fastener, or the like, which facilitates the manufacturing work, and can achieve a reduction in cost particularly when mass-produced. Since the board main body 13 and the decorative edge 17 are in close contact with each other while suppressing the occurrence of a gap between these boundary portions, the appearance quality is improved and the reliability as a product is improved.

In the second embodiment, the board main body 13 is made of resin, and the resin board main body 13 includes a pair of plate portions 13a that are spaced apart from each other and a connection portion 13b that connects the pair of plate portions 13a to each other. And. For this reason, the board main body 13 can ensure the strength in the direction connecting the pair of plate portions 13a with each other by the connecting portion 13b, and the reliability of the bath lid 11 is improved.

In the second embodiment, the connecting portion 13b extends in the X direction between one end and the other end along the surface of the pair of plate portions 13a, and the pair of plate portions 13a A plurality of hollow portions 13c are formed between the plurality of Y-directions that are spaced apart in the Y-direction intersecting the X-direction along the surface. By providing the board body 13 with the hollow portion 13 c, weight reduction can be achieved while maintaining strength, and the heat insulation as the bath lid 11 is improved.

In the second embodiment, a cap 15 that closes 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 decorative edge 17 is integrally molded with the peripheral edge of the board body 13, the inflow of the resin into the hollow portion 13c can be suppressed.

In the second embodiment, the cap 15 connects a plurality of insertion portions 15a that are individually inserted into the plurality of openings 13c1 and the end portions on the side protruding from the openings 13c1 of the plurality of insertion portions 15a. 15b.

For this reason, the cap 15 is not exposed to the outside, and the appearance quality is further improved. Since the board main body 13 is made of resin, by using a transparent resin, the state in the bathtub can be confirmed through the board main body 13 without using the bath lid 11 during use, and convenience is improved.

[Modification of Second Embodiment]
Next, a modification of the second embodiment is shown. The bath lid of the modified example is the same as the bath lid 11 of FIG. 5 in appearance. FIGS. 13A to 13C show a state before the resin decorative edge 17 shown in FIG. 5 is molded, but will be described as a bath lid 110 for convenience.

The bath lid 110 uses a resin board body 13 similar to the bath lid 11 of the second embodiment. The main difference between the bath lid 110 and the bath lid 11 is that a concave cap 16 shown in FIG. 13D is attached to the concave portion 13d of the board body 13 shown in FIG.

As shown in FIGS. 13B and 13D, the recess cap 16 includes an insertion portion 16a that is inserted into the recess 13d, and a head portion 16b that connects ends of the insertion portion 16a that protrude from the recess 13d. Yes. The fitting portion 16a has a substantially rectangular parallelepiped shape corresponding to the elongated rectangular parallelepiped concave portion 13d, and is in close contact with the inner surface of the concave portion 13d while being inserted into the concave portion 13d.

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

The length of the head portion 16b in the longitudinal direction (corresponding to the X direction of the board body 13) is substantially equal to the length of the pair of plate portions 13a in the X direction. The head portion 16b is formed by bending an end surface portion 16b1 that closes the proximal end side of the hollow portion of the insertion portion 16a, and bending by 90 degrees from the left and right side edges of the end surface portion 16b1 toward the curved surface 16a1 side in FIG. 13B. A pair of flanges 16b2.

The protruding portion 16b2 has a protruding length from the end surface portion 16b1 shorter than the protruding length from the end surface portion 16b1 of the fitting portion 16a, and covers the surface of the plate portion 13a in the vicinity of the opening side of the recessed portion 13d of the board body 13. A flange clearance 16d is formed between the flange 16b2 and the fitting portion 16a. With the recess cap 16 attached to the board main body 13, the protruding portion 13a1 of the board main body 13 enters the flange gap 16d. The length of the fitting portion 16a in the longitudinal direction (corresponding to the X direction in FIG. 6) is shorter than the length of the flange portion 16b2 in the longitudinal direction. Thereby, when the cap 16 for recessed parts and the cap 15A mentioned later are attached to the board main body 13, interference with the insertion part 16a and the insertion part 15a is prevented.

FIG. 13E is a plan view of the periphery of the end portion in the longitudinal direction of the cap 15A that closes the hollow portion 13c shown in FIG. 6, and the concave cap 16 is indicated by a two-dot chain line. FIG. 13F is a view on arrow J in FIG. 13E. The overall shape of the cap 15A is substantially the same as the cap 15 of the second embodiment shown in FIGS. 7 and 8, but the shape of the end portion in the longitudinal direction is different as shown in FIG. 13E.

The end portion in the longitudinal direction of the cap 15A includes an arc surface 15e in which the outer peripheral surface of the head portion 15b has an arc shape, and a flat contact surface 15f bent from the end portion of the arc surface 15e toward the fitting portion 15a. ing. An arc surface 16e and an abutment surface 16f similar to the arc surface 15e and the abutment surface 15f are also formed at the end on the concave cap 16 side. As shown in FIG. 13E, the length of the arc surface 16e is shorter than the length of the arc surface 15e, but may be equivalent. The arc surface 15e and the arc surface 16e form a continuous arc surface P as shown in FIG. 13A. The contact surface 15f and the contact surface 16f are in contact with each other in a substantially close contact state. The aforementioned arc surface P is formed by the contact surface 15f and the contact surface 16f contacting each other.

The bath lid 110 shown in FIG. 13A before molding the decorative edge 17 is in a state in which the entire circumference of the outer peripheral edge of the board body 13 is surrounded by the two caps 15 A and the two concave caps 16. In this state, the decorative edge 17 is integrally formed of resin on the entire periphery of the four

caps

15A, 16 in the same manner as the bath lid 11 shown in FIG.

In the modification of the second embodiment, not only the cap 15 that closes the opening 13c1 is attached as in the second embodiment, but also the concave cap 16 that closes the concave 13d is attached. For this reason, when the decorative edge 17 is integrally molded with the peripheral edge of the board main body 13, the inflow of the resin into the hollow portion 13c can be suppressed, and the inflow of the resin into the recess 13d can be suppressed.

Further, in the modified example, as shown in FIG. 13E, the outer peripheral surface of the contact portion between the cap 15 and the concave cap 16 is an arc surface P. For this reason, when the decorative edge 17 is molded, the resin easily adheres to the arc surface P, and the reliability is improved.
