Description

[Detailed description of the invention] This invention relates to a pillow that exhibits an excellent acupressure effect, a cooling sensation, and cushioning properties, and can provide a comfortable sleeping experience.

Conventionally, pillows filled with buckwheat hulls, rice hulls, etc., pillows filled with panya, feathers, urethane foam chips, etc., and ceramic pillows have been used, but pillows filled with buckwheat hulls, rice hulls, etc. are susceptible to mold. There is a possibility of the infestation of insects and hygiene, and pillows filled with bunya, feathers, urethane foam chips, etc. are too soft and have poor heat dissipation, and ceramic pillows have problems with hardness. In addition, there are many pillows on the market that aim to achieve effects such as acupressure, but most of these pillows are either too hard and cause discomfort during use, or are too soft and do not provide sufficient acupressure effects. There were pros and cons.

This idea was made in view of the above circumstances,
Moderate acupressure effect, cooling sensation, good breathability,
The object of the present invention is to provide a pillow that has appropriate cushioning properties and a sense of stability.

This invention will be explained in detail below with reference to the drawings.

The drawing shows an example of the pillow of this invention, and the reference numeral 1 in the drawing is a pillow obtained by this invention, and this pillow 1 is composed of a core material 2, a plate body 3, a bag body 4, and a cover 5. There is. The core material 2 forms the core of the pillow 1 and is made of ordinary urethane foam, foam rubber, or a laminate of urethane foam and foam rubber. A concave and convex structure that fits into each other is used to enhance the acupressure effect and cushioning properties. A plate body 3 is attached to one surface of the core material 2 and is provided integrally with the core material 2. This plate body 3 is made of a relatively rigid and harder material than the core material 2, such as a foamed polyethylene sheet, a heat compression molded urethane foam sheet, a high hardness urethane foam sheet, and a foamed polyvinyl chloride sheet, and is thermoformed into an uneven shape. From the viewpoint of the acupressure effect and the firmness of the pillow, it is suitable that the pillow has an uneven shape with a height of 5 to 15 mm and a diameter of 20 to 30 mm. In addition, by heating and compressing general urethane foam, its thickness can be reduced to 1/6 to 1/6 of the original thickness.
A thermocompression molded urethane foam sheet with a size of 1/9 has good air permeability, so it can be suitably used. In this plate body 3, the core material 2 is attached to the urethane foam side of a laminated product of urethane foam and foam rubber. The plate body 3 and the core material 2 may be attached to each other not only by adhesive but also by thermal fusion of both members.

A bag body 4 is provided on the other surface of the core material 2 by means such as sewing. The bag 4 is divided into a plurality of parts (three in the drawing) over the entire pillow 1, and a synthetic resin granule 6 is sealed inside the divided bag 4. As the synthetic resin granules 6, polystyrene beads having a diameter of about 1 to 4 mm are used, and expanded polystyrene beads are particularly preferred in terms of weight and thermal conductivity. Due to the bag body 4 and the granules 6, the pillow 1 is comfortable to sit on when in use, and a good sense of stability can be obtained when the head is placed on it.
Next, a cover 5 is provided to cover the pillow body having a three-layer structure of the core material 2, the plate body 3, and the bag body 4, thereby obtaining the pillow 1 according to this invention.

The pillow 1 constructed in this way uses a laminate of foam rubber and urethane foam as the core material 2, so it exhibits optimal elasticity as a pillow, and the core material 2
Since the plate body 3 has an uneven structure on one side and has a slightly high rigidity, an excellent acupressure effect can be obtained, and it is also highly breathable and can provide a cool feeling. In addition, the other side of the core material 2 is provided with a bag body 4 divided into a plurality of pieces, and the synthetic resin granules 6 are sealed in the bag body 4, so that the pillow 1 can sit comfortably and the head It provides a sense of stability when placed on it.
Due to the combination of the above effects, the pillow 1 according to this invention
It has a well-balanced feeling of coolness, cushioning, and stability, and also has a moderate acupressure effect.

As explained above, the pillow of this invention uses an elastic foam as a core material, and a plate body that is harder than the core material and has an uneven structure is provided on one side of the core material, and a plate body that is harder than the core material and has an uneven structure is provided on the other side of the core material. Since the bag is divided into multiple parts and the synthetic resin granules of the bag are enclosed, it has excellent cooling sensation, cushioning properties, and stability, and has a good balance of these properties, allowing for moderate acupressure. It is effective and provides excellent sleeping comfort. In addition, it has excellent hygienic advantages, such as no generation of dust, dirt, mold, or insects.
