Description

[Detailed description of the invention] The present invention relates to a bathtub pillow that is used by being attached to the upper part of the inner wall of a bathtub. One hole 3 is used as a foamed resin injection hole 3a, and the other hole 3 is used as an air release hole 3b, and a nut 4 fitted in this hole 3 is attached to a suction cup, etc. This relates to a pillow for a bathtub, in which a bolt 10 of an accessory part 5 is screwed to close a hole 3.

In this type of bathtub pillow where the hollow interior of the pillow outer shell is filled with foamed resin, the pillow outer shell has a hole for injecting the foamed resin and a hole for venting the air inside when injecting the foamed resin. It is necessary to provide However, after injecting the foamed resin, it is necessary to close this hole, but conventionally, this hole is closed with a lid, plug, tape, etc., which requires a special member to close the hole, which increases costs. In addition to being a cause, these members were exposed to the outside and spoiled the appearance.

The present invention has been developed in view of the above points, and it is possible to close the foam resin injection hole and air release hole of the pillow outer shell using the attached parts, and a special member for blocking the hole. It is an object of the present invention to provide a pillow for a bathtub, which eliminates the need for the pillow and improves the appearance.

The present invention will be explained in detail below with reference to Examples. Pillow outer skin 1
is formed hollow inside by blow molding a soft resin such as polyethylene, and has a triangular side surface as shown in FIG. A plurality of (three in the illustrated embodiment) holes 3 are provided on the lower surface of the pillow outer skin 1. The hole 3 is formed by a cylindrical portion 6 provided to protrude inward from the pillow outer skin 1 and an opening 7 bored at the tip of the cylindrical portion 6. The cylindrical portion 6 is formed into the pillow outer skin by blow molding. 1, and then an opening 7 is formed at the tip of the cylindrical portion 6 with a drill or the like. In addition, a third
As shown in the figure, a nut 4 is inserted and attached during blow molding, and the screw hole 8 of this nut 4 is aligned with the opening 7. Reference numeral 9 denotes a groove provided all around the outer circumference of the nut 4, which prevents the cylindrical portion 6 from biting into the groove 9 and the nut 4 from coming off from the cylindrical portion 6.

Of the three holes 3 provided as described above, for example, the center hole 3 is used as a foam resin injection hole 3a, and a foam resin such as soft polyurethane foam is inserted from here.
The pillow outer skin 1 is made by injecting the undiluted solution and causing it to foam inside the pillow outer skin 1, and by using the holes 3 on both sides as air vent holes 3b, the air inside the pillow outer skin 1 is extracted from there by the volumetric expansion of the foamed resin 2 accompanying the foaming. The hollow inside of is filled with foamed resin 2. After filling the foamed resin 2 into the pillow outer shell 1 in this way, the attached parts 5 such as the suction cup 5a and the stopper 5b are screwed into the nuts 4 with the bolts 10 attached to their respective bases, as shown in FIG. The bolt 10 of the accessory part 5 is thus screwed into the nut 4 to close the hole 3 with the bolt 10. In the illustrated embodiment, the suction cups 5a are attached to the air vent holes 3b on both sides, and the stopper 5b is attached to the resin injection hole 3a in the center.

The bathtub pillow obtained as described above is attached to the upper part of the inner wall of the bathtub 11 with a suction cup 5a as shown in FIG.
b.

As mentioned above, in the present invention, a bolt of an accessory such as a suction cup is screwed into a nut fitted into a hole formed in the pillow outer skin as a foam resin injection hole or an air vent hole to open the hole. Since the hole can be closed, the hole can be closed using an attached part such as a suction cup, and there is no need for a separate special member such as a lid, which reduces costs. There is no fear that the appearance will be damaged by exposure. Further, since the hole is closed by screwing the bolt into the nut, the nut and bolt have a strong connection, and the hole can be more firmly closed than with a simple lid or tape.
