Description

[Detailed Description of the Invention] The present invention relates to a bath lid that is novel and has great industrial applicability.

Recently, bath lids are becoming more and more common,
Efforts to improve defects such as lack of strength and sliding ability with the top surface of the periphery of the bathtub, etc., which have been seen in accidents where children climbed on the bathtub lid and fell into the bathtub, or to improve insulation and heat retention effects. Various new bath lids have been developed, but it is extremely difficult to satisfy all of these diverse requirements, and they tend to increase weight and cost, making them impractical. There were some areas that were seriously lacking.

In view of the drawbacks of conventional bathtub lids, the present invention has developed a bathtub lid that has sufficient strength and superior heat retention effect at an extremely low cost, and has no risk of slipping off from the top of the bathtub. The object is to be able to supply it in any shape.

Next, the configuration of the present invention will be specifically explained with reference to drawings showing embodiments.

1...1 are unit flat hollow bodies molded from thermoplastic resin, which are arranged in parallel with a slight gap d between them to form an arbitrary bath lid shape. shall be taken as a thing.

In molding the unit flat hollow body 1, units of each standard may be integrally molded, but a long flat cylindrical body is molded and the flat cylindrical body is cut appropriately to the desired length. After that, if the openings on the front and rear surfaces are closed, the cost can be reduced by mass production, which is effective.

The type of thermoplastic synthetic resin forming the unit flat hollow body 1 is not limited, but in view of the heat resistance, durability, shape retention, etc. required as a material for the bath lid, polyvinyl chloride, polyvinyl chloride, Polypropylene, polycarbonate, polyethylene, etc. are suitable.

2 is wrapped around the entire circumference of a combination of a plurality of unit flat hollow bodies 1...1 forming a bath lid shape as described above, and the unit flat hollow bodies 1...1 are coated and coated. Thermoplastic material that forms one bath lid 3 as shown in FIGS. 2 and 3 by fusing and integrating a plurality of unit flat hollow bodies 1...1. It is a synthetic resin sheet or a nonwoven fabric, and the surface 21 is formed with a rough surface to prevent slipping.

There is no limitation on the material of the thermoplastic synthetic resin sheet 2, but it has the above-mentioned heat resistance required as a material for a bath lid.
In addition to durability and shape retention, polyvinyl chloride, polypropylene, polyester, polycarbonate, polyethylene, etc. are suitable in consideration of fusion properties, and furthermore, this thermoplastic synthetic resin sheet 2 and the unit flat hollow body described above are suitable. By using the same material for 1, the fusion properties can be further improved.

Note that even if a thermoplastic synthetic resin film is used instead of the thermoplastic synthetic resin sheet 2, this does not depart from the gist of the present invention.

As a method for roughening the thermoplastic synthetic resin sheet or nonwoven fabric 2, the surface may be roughened during molding of the thermoplastic synthetic resin sheet or nonwoven fabric 2, or embossing may be performed after molding.

Methods for fusing thermoplastic synthetic resin sheets or nonwoven fabrics 2 to unit flat hollow bodies 1...1 include heat fusing, ultrasonic fusing, high frequency fusing, electron beam fusing, etc. The bonding method shall be selected as appropriate, taking into consideration the shape of the unit flat hollow bodies 1...1, the material of the thermoplastic synthetic resin sheet or nonwoven fabric 2, and other various conditions at the time of fusing.

In the present invention, as shown in FIG. 4, by erecting a reinforcing partition wall 5 in the vertical direction of the center of the cavity 4 of the unit flat hollow body 1 used, the desired strength and heat insulation/heat retention effect of the bath lid 3 can be achieved. This is the reason why it becomes even bigger, and it is extremely effective.

The effects of the present invention reside in the following points.

(a) Since the base is a combination of unit flat hollow bodies 1...1 integrally molded from thermoplastic synthetic resin, the air in each unit flat hollow body 1...1 is stored. The insulation and heat retention efficiency of the cavity 4 is extremely remarkable,
In this respect, it has a special effect compared to conventional bath lids.

(b) The bath lid 3 of any shape can be formed by combining unit flat hollow bodies 1...1 of various shapes manufactured by a mass production method, and the unit flat hollow bodies 1...1 The combination of the above and the coating of these unit flat hollow bodies 1...1 can be performed in a single process, and in this respect, it is possible to immediately respond to the demand for bath lids of various shapes, and it is possible to significantly reduce costs.
In this respect, it has an extremely remarkable effect.

(C) By erecting the reinforcing partition wall 5 in the cavity 4 of the unit flat hollow body 1...1, not only can the strength be greatly improved, but also the above-mentioned heat insulation and heat retention effect can be increased. (d) The same slight distance d between the adjacent unit flat hollow bodies 1, 1 allows water droplets to collect on the surface of the bath lid 3 formed by covering and fusing the thermoplastic synthetic resin sheet or nonwoven fabric 2. In this respect, it is effective.

(e) Since the surface is roughened, there is no risk of slipping down the periphery of the bathtub, and even if a child climbs onto the top surface, there is no risk of falling.
