Description

  The present invention relates to a bathtub pillow that is used by being fixed to a bathtub surface, and relates to a bathtub pillow that prevents water from penetrating into a cushion portion made of a foam and impairing cushioning properties and generating mold.

  There is a bathtub pillow that can be fixed to the bathtub as a pillow for use when relaxing by having the neck and head held at the peripheral edge of the bathtub during bathing. As a pillow for a bathtub, for example, an elastic body made of a foamed resin such as urethane is used as it is, or the elastic body as described above is used as a cushion part, and the cushion part is covered with a sheet made of resin. Is used.

  However, since it is first used in the bathroom and is always used in contact with water or hot water, there is a problem in that water soaks into the cushion portion made of foam or the like. If the cushion part contains water, good cushioning properties cannot be obtained, and molds are generated.

  In addition, there are proposals such as making the cushion part with foam of closed cells so as not to contain water, and suppressing the generation of mold by adding a fungicide to the resin, but it is always a sufficient measure There is also a cost problem.

  Accordingly, an object of the present invention is to provide a bathtub pillow that prevents water from penetrating into the cushion portion and solves problems such as deterioration of good cushioning properties and generation of mold in the cushion portion.

  In order to achieve the above object, the present invention attaches to a bathtub surface composed of a cushion part made of a resin foam and a cover material made of an ethylene vinyl acetate copolymer resin covering the cushion part. In the bathtub pillow used, the cover material and the cushion portion are fixed on the surface, and the end portions of the cover material are overlapped and melted and integrated.

  Since the cover material is completely bonded and fixed to the cushion portion as in the present invention, there is a problem that the cover material is wrinkled even if the user moves or moves on the pillow. In addition, even if water has permeated, it is possible to prevent the water from moving and diffusing in the cover material. In addition, since the end of the cover material is fused and integrated, there is no gap or interface, so that water hardly enters.

  Hereinafter, the bathtub pillow of the present invention will be described in detail.

  FIG. 1 is a plan view of a bathtub pillow according to the present invention, and FIG. 2 is a cross-sectional view taken along line AA in FIG. The bathtub pillow 1 has, for example, an arc shape as shown in FIG. 1, and the shape is determined by the shape of a handrail of the bathtub to be attached. 2 has a structure in which the cushion material 2 is covered with the cover material 3, the cushion material 2 provides cushioning properties, and the cover material 3 serves to prevent water from entering the inside. It plays the role of fulfilling and giving a good touch. The cushion material 2 is made of a material such as low-resilience urethane foam or urethane gel, and is entirely covered with a cover material made of ethylene-vinyl acetate copolymer resin.

  In this configuration, if water penetrates into the cover material 3, there is a problem that the cushioning property is lowered and the feeling of use is lowered, and mold is generated in the cushion material 2 inside the cover material 3. There is a problem that the sense of cleanliness is impaired.

  In addition, if the cover material 3 is wrinkled or misaligned during use, the user may feel uncomfortable on the head, or the cover material 3 may deteriorate and break at an early stage. It also becomes a problem.

  Therefore, in the bathtub pillow of the present invention, the cover material 3 and the cushion material 2 are fixed by means such as adhesion or fusion with an adhesive, and the cover material 3 and the cushion material 2 are displaced. In addition, the cover material 3 is less likely to be wrinkled.

  When the cover material 3 and the cushion material 2 are bonded and fixed on the entire surface, even if the user moves the head left and right and up and down on the pillow, the cover material 3 moves with respect to the cushion material 2 only. In addition, since there is no space between the cover material 3 and the cushion material 2, the generation of wrinkles can be almost eliminated.

  Further, in the bathtub pillow 1 of the present invention, since the end portions of the cover material 3 covering the entire surface of the cushion material 2 are overlapped and fused together, the cushion material 2 is completely sealed by the cover material 3. This prevents water from entering the cover material 3. By preventing the ingress of water, it is possible to prevent a decrease in cushioning properties and generation of mold.

  The cover material 3 is preferably a soft material that is soft to the touch, and may be a soft elastomer sheet such as polyurethane, polystyrene, or polyolefin-based thermoplastic elastomer. Examples include coalesced resins.

  FIG. 3 is a cross-sectional view of the lower mold 5 along with the cover material 3, and FIG. 4 is a cross-sectional view of the cover material 3 being fused. The method for manufacturing a bathtub pillow according to the present invention can be manufactured, for example, by the following method.

  A soft elastomer sheet for forming the cover material 3 is arranged on the lower mold 5 having the predetermined shape of the bathtub pillow 1 and is brought into close contact with the shape of the lower mold 5 by means such as heating and vacuuming. After that, the cover material 3 is corona-treated with a spray-type corona treatment machine 6. A foamed urethane raw material for forming a cushioning material 2 made of low-resilience urethane foam is injected onto a soft elastomer sheet subjected to corona treatment, and an upper mold (not shown) is attached, and foamed in a mold to be cushioned. By molding the material 2 and then cooling and taking it out of the mold, it is possible to obtain a state where the cover material 3 and the cushion material 2 are in contact with each other on the entire surface.

  Subsequently, a new soft elastomer sheet is placed in the mold, and is also brought into close contact with the shape of the upper mold by means such as heating and vacuuming, and heating is performed to mold. The molded sheet is taken out of the mold, the surface of the sheet is corona-treated, and the cushion material 2 is foam-molded and bonded in the cover material 3, and the adhesive 4 is applied to the cushion material 2. Then, the molded sheets are bonded together. By performing the corona treatment, a material such as an ethylene-vinyl acetate copolymer resin, which is difficult to be thermally fused with other materials or bonded with an adhesive, can be satisfactorily fused and bonded. After completing the shape of the pillow in this way, the ends 3a of the cover material 3 made of two soft elastomer sheets are overlapped with each other and heated by means such as heating using the high-frequency heating electrode 7. Although the pressure is bonded to each other, the entire bonding surface is completely melted and integrated, and the cushion material 2 can obtain a bathtub pillow completely sealed by a cover material.

  The present invention can maintain cushioning properties even when used in contact with water as a pillow for a bathtub used by being attached to the bathtub, and can prevent mold and the like from being generated inside.
