Description

[Detailed description of the invention] The present invention relates to a bathtub pillow that is installed and used in a bathtub, and the pillow outer shell 1 is made by filling a foamed resin 2 into an inner hollow pillow shell 1 formed by blow molding.
A foamed resin injection port 3 and an air bleed port 4 are formed on both end faces of the foamed resin injection port 3 and an air bleed port 4, respectively, and closing portions 6, 6 protruding from the inner surfaces of the end covers 5, 5 are formed in the foamed resin injection port 3 and air bleed port 4, respectively. This relates to a pillow for a bathtub, in which end covers 5, 5 are attached to both end surfaces of a pillow outer skin 1, respectively, and the ends 3, 4 are closed by being connected to each other.

As shown in FIG. 5, the inner hollow pillow outer shell 1 of the bathtub pillow is made by extruding a parison 8 into a cylindrical shape and molding it into a split mold 7.
It is formed by blow molding in which air is blown into the parison 8 between the parisons 7 and 8. However, split mold 7,7
In the case of blow molding, a parting line, which is the boundary line where the split molds 7 and 7 coincide, is formed linearly as a parting line mark 9 on the outer surface of the pillow outer skin 1, as shown in FIG. That will happen. Of these parting line marks 9, those formed on the outer peripheral surface of the pillow outer skin 1 are parting line marks 9.
By designing the split mold 7 so that the parting line marks 9 are on the back or bottom surface of the pillow outer shell 1, the appearance of the pillow outer shell 1 is not spoiled by the parting line marks 9. The parts formed on both end faces of the pillow outer cover 1 are inevitably exposed to the outside, and the exposed parting line traces 9 spoil the appearance of the pillow outer cover 1.

The present invention has been made in view of the above points, and utilizes a member for closing the foamed resin inlet and air vent formed in the pillow outer shell to form parting line marks on both end surfaces of the pillow outer shell. The object of the present invention is to provide a pillow for a bathtub that can hide the inside of a bathtub.

The present invention will be explained in detail below with reference to Examples. Pillow outer skin 1
is formed by blow molding a soft resin such as polyethylene into a hollow interior with a triangular side profile, and holes are drilled on both end faces to serve as air inlets during blow molding, and one hole is is used as a foamed resin injection port 3 to inject the stock solution of foamed resin 2 such as soft foamed polyurethane from here to foam inside the pillow outer skin 1, and the other hole is used as an air vent 4 to foam the air inside the pillow outer skin 1. The foamed resin 2 is extracted due to the volumetric expansion caused by this. In this way, the hollow interior of the pillow outer skin 1 is filled with the foamed resin 2. After filling the foamed resin into the pillow outer skin 1, the end covers 5, 5, which are formed by injection molding or the like to have the same shape as the side surface shape of the pillow outer skin 1, are closed. By press-fitting the parts 6 into the foam resin inlet 3 and the air vent 4, they are attached to both end surfaces of the pillow outer skin 1 as shown in FIGS. 2 and 3. In this way, the foamed resin inlet 3 and the air vent 4 are closed with the closing part 6, and the end covers 5 cover both end surfaces of the pillow outer skin 1 to hide the parting line marks 9 on both sides of the pillow outer skin 1. It is something. In the embodiment shown in FIG. 4, a nut 10 is inserted into the foamed resin injection port 3 and the air vent 4 during blow molding, and a bolt 6a is provided as a closing portion 6 by protruding from the end cover 5. By screwing the bolt 6a into the nut 10, the foamed resin inlet 3 and the air vent 4 are closed, and the end cover 5 is attached.

The bathtub pillow formed as described above is used by being attached to the upper part of the inner wall of the bathtub.
If the pillow outer skin 1 is formed into an isosceles triangular side surface as in the above embodiment, the end cover 5 of the same shape, which is injection-molded with one mold, can be placed on either the left or right side end surface of the pillow outer skin 1. can also be installed.

As mentioned above, in the present invention, a foamed resin inlet and an air vent are formed on both end surfaces of the pillow outer skin,
The closing parts protruding from the inner surface of the end cover are connected to the foam resin injection port and air vent to close both ports, and the end covers are attached to both end surfaces of the pillow outer shell, so that the foam resin injection port can be closed. Both end surfaces of the pillow shell can be covered with an end cover formed with a protruding blocking part for blocking an inlet or an air vent, and a member used for blocking a foamed resin injection port or an air vent. This can be used to hide the parting line marks on both end faces of the pillow outer shell, and by forming the pillow outer cover and end covers in different colors, it is also possible to form a bathtub pillow in multiple colors. It becomes possible.
