る。 The lid constituent members 1, 2, and 3 are each made of hard vinyl chloride and have a length slightly longer than the depth dimension of the bathtub B. The lid components 1 and 2 have their longitudinal directions rotated by 180 degrees, and have substantially the same structure, with a flexible connecting piece extending from the bottom surface of one side in the width direction. 1a and 2a project over the entire length, and are provided with hard dovetail-shaped protrusions 1b and 2b over the entire length at the upper and lower center portions on the other side in the width direction, and a cylindrical interior. There are multiple ribs on the top and bottom walls.
c, 2c are formed in the thickness direction. The lid component 3 also has a dovetail-shaped protrusion 3b extending over its entire length along the upper and lower central portions of both sides in the width direction, into which the dovetail-shaped protrusions 1b and 2b are to be inserted. 3b, and is connected to the lid constituent members 1, 2 by engaging the protrusions 1b, 2b of the lid constituent members 1, 2 with the protrusions 3b, 3b. One side in the width direction where each connecting piece 1a, 2a of the lid component members 1, 2 extends is a connecting piece 1.
By heat-sealing a and 2a to each other, the lid constituent members 1 and 2 are directly connected.

組み合せて採用することとしてもよい。 Although there are no particular limitations on the manufacturing method of each lid component 1, 2, and 3, the lid components 1 (or 2) and 3 are usually extruded in the longitudinal direction using separate molds. It is manufactured by forming a long object and cutting it to a fixed length. Lid components 1 and 2 can be interchanged by simply changing their orientation, so by changing the orientation of the lid component cut to a regular length, connecting piece 1 is created.
a and 2a are integrally bonded together by heat fusion, and then one side in the width direction is connected to each other by a lid forming member 3 to be assembled to a desired length. Note that several types of lid constituent members 3 with different width dimensions are prepared and are selectively adopted so that they can be assembled according to the required length of the bath lid. Of course, the width dimension of the lid component 3 may be constant, and a plurality of types of lid components 1 and 2 having different width dimensions may be prepared, and a combination of these may be employed.

もよい。 The plugs 4 and 5 are for protecting fingers from the edges of the lid components 1, 2, and 3, and are made of soft vinyl chloride and have a thickness of about 2 to 3 mm. On one side of the base portions 41, 51, which are formed to have approximately the same contour as the cross-sectional shapes of the members 1 (or 2), 3, are ribs 1c, It is configured by providing a plurality of plug portions 42, 52 which are divided into sections 2c and formed so as to be able to be fitted into the interior by force fitting, and the lid component 1 is attached with an adhesive applied to the surfaces of the plug portions 42, 52. , 2 and 3 are fitted and fixed to the openings at both ends. The plugs 4, 5 are formed with grooves 43, 53 extending over their bases 41, 51 and plug portions 42, 52, so that the plugs 4, 5 can be inserted into the openings at both ends of the lid components 1, 2, 3. When fitted, the grooves 43 and 53 form drain holes through which the inside and outside of the lid constituent members 1, 2, and 3 communicate with each other. Note that the plugs 4 and 5 do not necessarily need to be provided.

ない。 In the present product constructed as described above, the lid constituent members 1 and 2 are flexible connecting pieces 1a and 2a.
The lid constituent members 1, 2 and the lid constituent member 3 are connected by heat-sealing them together, and by fitting the engaging protrusions 1b, 2b and the engaging grooves 3b, 3b. As a result, the structure of the manufacturing mold for each of the lid constituent members 1, 2, and 3 is simplified, and the equipment cost is reduced, of course, and the yield is greatly improved, and the efficiency of the connection work in the width direction is high. This will improve production efficiency and significantly reduce product costs.
Further, as mentioned above, the lid constituent members 1, 2, and 3 are connected to each other by the fitting of the connecting pieces 1a, 2a, the grooved stripes 3b and the protruding stripes 1b, 2b, so that the fused connecting pieces 1a,
It can be folded at 2a, and when not in use, it can be folded neatly and compactly and placed against a wall, etc., so that it does not get in the way, and when it is transported, it is not bulky and can be transported efficiently.
Moreover, since the lid components 1, 2 and 3 can be removed by removing the stoppers 4 and 5, they can be adjusted to suit the size of other baths of different sizes. It is also possible. In addition, although the above-mentioned embodiment described the structure in which the lid constituent members 1 and 2 are formed individually and then the connecting pieces 1a and 2a are joined to each other, it is also possible to integrally extrude them in a mutually connected state. Needless to say.
