Description

  The present invention provides, for example, a bathtub lid that can be mounted on a bathtub provided with an uneven portion such as a corrugated surface on the periphery of the bathtub, with a gap eliminated from the bathtub as much as possible, and It relates to the manufacturing method.

Conventionally, as a bathtub, in general, the upper surface of the edge portion is often formed to be substantially flush over the entire circumference. As a bathtub lid used for the purpose of covering and maintaining the upper surface of a bathtub having such a general structure, a set of two sheets has substantially the same shape (rectangular shape in plan view, etc.) as the size of the bathtub. A flat-plate bathtub lid made of a hard material formed (see Patent Document 1), and a retractable shutter-type bathtub lid formed by connecting a large number of elongated hollow members made of a hard material in parallel (Patent) Document 2) is known.

  By the way, in recent years, in addition to the conventional bathtub in which the upper surface of the edge as described above is formed substantially flush over the entire circumference, for example, irregularities such as a corrugated shape are formed on at least a part of the peripheral edge of the bathtub. The assigned configuration (see, for example, FIG. 3) has been put on the market. Such a bathtub is also called a “design bathtub”.

  However, when the conventional bathtub lid is placed on a bathtub having a corrugated shape or the like on the surface of the peripheral edge, many large gaps are generated between the peripheral edge of the bathtub and the peripheral edge of the bathtub lid. As a result, there is a problem that sufficient heat insulation cannot be performed and moisture is filled in the bathroom. Thus, the actual condition is that there has never been a bathtub lid that can be applied to a bathtub in which an uneven shape is provided on at least a part of the surface of the peripheral edge.

  The present invention has been made in view of such a technical background, and a gap is provided between the bathtub and a tub having a configuration in which irregular shapes such as corrugations are provided on at least a part of the surface of the peripheral edge. It aims at providing the bathtub lid which can be mounted in the state excluded as much as possible, and its manufacturing method.

In the invention of [1], since the soft edge portion has flexibility, when this bathtub lid is put on the upper surface of the bathtub, an uneven shape such as a waveform is imparted to at least a part of the surface of the peripheral edge of the bathtub. And since a soft edge part adapts to uneven | corrugated shapes, such as a waveform of the surface of the peripheral part of a bathtub, it can eliminate as much as possible that a clearance gap is made between the peripheral part of a bathtub and the peripheral part of a bathtub lid. Furthermore, since the soft member is enclosed in the synthetic resin bag body to form the soft edge portion, the soft edge portion is sufficiently adapted to the uneven shape such as the corrugation on the surface of the peripheral edge of the bathtub.

In the invention of [2], since it is possible to bend according to the uneven shape of the bathtub upper surface by its own weight, if this bathtub lid is put on the bathtub upper surface, a waveform is formed on at least a part of the peripheral surface of the bathtub. Even if the uneven shape such as, etc. is given, the soft edge is sufficiently adapted to the uneven shape such as the corrugation on the surface of the peripheral edge of the bathtub, and there is a gap between the peripheral edge of the bathtub and the peripheral edge of the bathtub lid Can be prevented. Furthermore, since the soft member is enclosed in the synthetic resin bag body to form the soft edge portion, the soft edge portion is sufficiently adapted to the uneven shape such as the corrugation on the surface of the peripheral edge of the bathtub.

In the invention of [ 3 ], the soft edge is sufficiently adapted to the uneven shape such as the corrugation on the surface of the peripheral edge of the bathtub.

In the invention of [ 4 ], since the soft edge is sufficiently along the uneven shape such as the corrugation on the surface of the peripheral edge of the bathtub, a gap is formed between the peripheral edge of the bathtub and the peripheral edge of the bathtub lid. Can be surely prevented.

In the invention of [ 5 ], the inside of the bag body is divided into a plurality of independent spaces, and a soft member is enclosed in each of these independent spaces, so that the soft member is unevenly distributed in the bag body even after repeated use. Therefore, a bathtub lid with excellent durability is provided.

In the invention of [ 6 ], since the heat insulating material is enclosed in the bag body, the heat retention as the bathtub lid can be significantly improved. Moreover, since a heat insulating material is enclosed in a bag body and the contact with the hot water of a bathtub is avoided, the heat insulation performance original with a heat insulating material is not impaired.

In the invention of [ 7 ], the heat retaining property as the bathtub lid can be further improved.
