Description

[Detailed description of the invention] The present invention is an improvement of a shutter-type bathtub lid that can be rolled up freely, which is made by connecting hollow members of appropriate length made of hard synthetic resin in parallel through a flexible and elongated connecting member. In particular, a thin film made of soft synthetic resin is integrally laminated and adhered to the entire continuous uneven surface formed by the hollow member and the connecting member to strengthen the connecting force by the connecting member and to prevent entrainment etc. The object of the present invention is to provide a shutter-type bathtub lid that eliminates unpleasant noises caused when hollow members made of hard synthetic resin collide with each other.

A hollow member made of hard synthetic resin in an elongated shape,
Shutter-type bathtub lids are already known, which are connected in parallel to each other to an appropriate width via connecting members made of soft synthetic resin, and can be rolled up to improve handling convenience. However, in this conventional shutter-type bathtub lid, cracks may develop in the connecting member over the years of use, or in the case of the fitting type shown in Fig. 3, the fitting protrusion may fall out from the groove. However, there is a problem that it becomes unusable. In addition, since the surface of conventional shutter-type bathtub lids is made up of hollow members made of hard synthetic resin, there is a drawback that when rolled inward, the hollow members collide with each other and produce unpleasant noises. Therefore, it has the disadvantage of being inferior in terms of shock absorption and having a poor feel.

Therefore, in the present invention, a thin film made of soft synthetic resin is integrally laminated and adhered to the entire body of the shutter-type bathtub lid to solve the above-mentioned drawbacks of the conventional shutter-type bathtub lid. A specific configuration is shown.

In the figure, 1 is a hollow member made of extruded hard synthetic resin, and 2 is a connecting member made of soft synthetic resin for connecting a large number of the hollow members 1. In the embodiment shown in FIGS. 1 and 2, the connecting members 2 are attached by gluing, welding, etc. to the lower surfaces of the hollow members 1 arranged in parallel at appropriate intervals, and the upper surface of the welding tank 3 is It is formed to a size that is large enough to substantially cover it. Further, in the embodiment shown in FIG. 3, in the groove 4 provided at one longitudinal end of the hollow member 1 made of hard synthetic resin, a groove made of soft synthetic resin provided at the other longitudinal end of the hollow member 1 is inserted. The protrusions 5 that form the connecting member 2 are fitted and connected to an appropriate width, and both embodiments have a structure in which the connecting member 2 can be wound around as a type of hinge.

The present invention provides a shutter-type bathtub lid having such a structure, in which the continuous uneven surface formed by the hollow member 1 and the connecting member 2, that is, the entire surface opposite to the surface facing the upper surface of the bathtub 3, , thin films 6 made of soft synthetic resin are integrally laminated and adhered to each other.

In the case of a shutter-type bathtub lid, the upper surface of the hollow member 1 has a mountain shape, and the part where the connecting member 2 is attached has a valley shape and a continuous uneven shape.
The thin film 6 is brought into close contact with the entire surface by pressing a pressure roller having grooves formed on the outer circumferential surface that match the irregularities of the bathtub lid surface, and it is preferable to apply an adhesive or a heating means as appropriate. The thin film 6 is made of a transparent soft synthetic resin, a suitable pattern is printed on one side of the thin film 6, and the continuous unevenness of the shutter-type bathtub lid is made by printing an appropriate pattern etc. on one side of the thin film 6, with the printed side facing downward. Since the printed surface is on the inside when the lid is brought into close contact with the shaped surface, it is possible to obtain a shutter type bathtub lid with a beautiful finish without peeling even after continuous use.

The shutter-type bathtub lid of the present invention has the above-mentioned structure, and since a thin film made of soft synthetic resin is closely formed on the continuous uneven surface, the connection between the hollow members through the connecting member is reinforced, and the connecting member Conventional problems such as cracks occurring or the fitting protrusion, which is a connecting member made of soft synthetic resin protruding from one end of the hollow member, falling out of the groove recessed at the other end of the hollow member, can be avoided. It is something that can be resolved.

Therefore, it is possible to provide a shutter type bathtub lid that is extremely durable. Since the entire surface is covered with a thin film made of soft synthetic resin, it is possible to give the surface a mirror-like gloss that cannot be obtained with conventional extruded shutter lids.
It is also possible to solve the conventional drawback that the hollow members rub against each other during rolling, etc., producing unpleasant noises. Furthermore, it is possible to provide a shutter-type bathtub lid that feels good to the touch and has excellent shock absorption properties.
