ール系樹脂が主に用いられてきた。2. Description of the Related Art As a lid for a bath, there is a shutter type made of plastic. A shutter-type bathtub lid is made up of a number of strip-shaped bodies that are connected in parallel with a joint plate, is foldable, and fits well with the bathtub opening. It is the mainstream. The main body of this shutter-type bathtub lid is manufactured by extrusion molding, but as a raw material thereof, a vinyl chloride resin has been mainly used because of its ease of processing and low cost.

求められているのが現状である。However, when this vinyl chloride resin is incinerated, it has the drawbacks that it produces a large amount of chlorine-based toxic and harmful gases, and it has a high heat calorie during incineration, which damages the incinerator and is therefore discarded. Processing was a big problem. For this reason, there are movements to regulate the use of vinyl chloride resin in household products, and in some countries it is currently prohibited. In Japan as well, there is no doubt that its use will be restricted in the future, and the present situation is that a new material to replace this is required.

事故に会う危険もあった。更に、比較的重量がある為、
幼児や老人にはその開閉が楽ではなかった。Further, vinyl chloride resin is poor in heat resistance and impact resistance, and when a bathtub lid is made of this as a raw material, it is likely to be melted due to overheating, and the lid may be damaged by a hand or a foot, so that the body is free. There was also the risk of unintentional infants and old people having unexpected accidents. Furthermore, because it is relatively heavy,
Opening and closing was not easy for infants and the elderly.

It is an object of the present invention to provide a recyclable shutter-type bathtub lid that does not occur, has a strong strength, and can prevent accidents caused by the bathtub.

˜70 parts by weight and 5 to 30 parts by weight of inorganic filler are extruded under heating to form a flat tubular main body 1 having a flat bottom plate portion 2 in the longitudinal direction.
Are arranged side by side at predetermined intervals so that their long sides do not contact each other in the lateral direction, and the bottom plate portions 2 between the main bodies 1 are connected by a ribbon-shaped soft synthetic resin joint plate 5, and The above problem is solved by closing both end openings 6 of the main body 1 with synthetic resin caps 7.

ロリーも低く、焼却炉を痛めるおそれが少ない。The external appearance is the same as that of the conventional shutter-type bathtub lid and can be used in the same manner, but the main body is a polypropylene resin or polystyrene resin 9 containing no halogen.
Since the resin composition is formed by mixing 5 to 70 parts by weight and 5 to 30 parts by weight of the inorganic filler, even if incinerated in an incinerator, a halogen-based poisonous substance such as vinyl chloride resin, No harmful gas is generated, and the heat calories at the time of incineration are low, so there is little risk of damaging the incinerator.

Furthermore, it is extremely lightweight and easy to carry, attach to and remove from the bathtub, and it has excellent heat retention and can prevent a decrease in hot water temperature. Further, it has higher heat resistance, impact resistance, and strength than vinyl chloride-based ones, and can prevent accidents during boiling.

Talc is particularly preferable. By adding 0.5 to 3 parts by weight in total of the stabilizer and the processing aid to 100 parts by weight of the resin composition, thermal stability, deterioration resistance and processability can be further improved. Examples of stabilizers include antioxidants and ultraviolet absorbers. Examples of the processing aid include metallic soap and ethylene wax. As a method of adding the stabilizer and the processing aid, a conventional method can be used, and thus detailed description thereof will be omitted.
