Abstract

PROBLEM TO BE SOLVED: To provide a comfortable and clean pillow which has such favorable air permeability as to favorably exhale moisture of hair even when a user goes to bed with half-dried hair after the user washed own hair, in which the head and around will not get sweaty, and the head to the neck can be tightly supported. SOLUTION: A recessed part 2 is provided at a center part of a bottom surface of a membraneless urethane foam member 1 in which foams between ribs in open cell urethane foam are eliminated, and a front side center part 3 of the membraneless urethane foam member 1 is a little recessed inward from side parts 4, 4'. The whole body of the membraneless urethane foam member 1 is covered with a bag body 7 formed of mesh 5 having air permeability as least on the upper surface side and provided with a zipper 6 which can be freely opened/closed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a pillow.

Conventionally, pillows have been filled with buckwheat hulls, fir hulls, and the like, and also have been filled with buns, feathers, urethane foam, and the like.

[0003] In the case of buckwheat hulls and fir husks, there is a possibility that mold and insects may be generated, and there is a problem in hygiene. Further, those filled with pans, feathers, urethane foam, etc., have the drawbacks that they are too soft and have poor heat dissipation. In particular, in the case of urethane foam, there is no air permeability, and there is a drawback that it is difficult to sleep because of stuffiness.

In recent years, cleanliness has been regarded as a problem, and frequent hair washing habits have been established. When bathing and washing hair before sleeping, it takes a long time for hair to dry, especially for women with long hair. The pillows are often semi-dry and stick to the floor. However, the conventional pillows have poor air permeability and heat radiation, and have a drawback that they are stuffy and difficult to sleep.

[0005] In the case of buckwheat hulls and fir hulls, the moisture of semi-dry hair accumulates inside the pillow, which tends to promote the occurrence of mold and insects.

[Problem to be Solved by the Invention] Even if it is on the floor with dry hair in the latter half of hair washing, it has good ventilation, radiates moisture well, does not stuff around the head, and is firmly supported from the head to the neck. And to provide pillows that are easy to sleep and hygienic.

[0006]

Means for Solving the Problems A filmless urethane foam (1) has a concave portion (2) at the center of the bottom of the open cell urethane foam (1) in which the spaces between the ribs of the cells are removed. Has a shape in which the front central portion (3) is slightly inward from the side portions (4) and (4 '), and the entire non-membrane urethane foam (1) has air permeability at least on the upper surface side. A bag (7) formed of a knitted fabric (5) and having a zipper (6) that can be freely opened and closed.
It is a pillow covered with.

[0007]

The upper surface of the bag (7) is formed of a knitted fabric (5) having air permeability, and the cushion material filled in the bag (7) is provided between the ribs of the cells of the open-cell urethane fume. Since it is formed of the non-film urethane foam (1) from which air has been removed, air permeability is secured at least in the direction excluding the bottom surface, and moisture and heat on the head are radiated.

In addition, since the bottom of the filmless urethane foam (1) has the concave portion (2) at the center of the bottom surface, the pillow where the weight of the head is heavy, the deflection due to the load becomes larger than the periphery, and The part sinks deeply, and it fits from the head to the neck and can provide firm and stable support.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a filmless urethane foam (1) has a multilayer structure having different foaming densities. In order to improve the diffusion of moisture, profile processing having a large number of irregularities is applied, and a material having a lower foaming density than the lower sheet (8b) is used to improve the feeling of contact.

The lower sheet (8b) of the membrane-free urethane foam (1) is hollowed out in a substantially elliptical shape so as to form a concave portion (2) in the center, and as shown in FIG. The front center part (3b) of the sheet (8b) of the layer is the first sheet.
The shape of the sheet (8a) of the layer is further inward from the front center portion (3a) of the sheet (8a). As shown in FIG. 3, the vicinity of the shoulder of the head and the neck easily sinks, and from the head to the neck. The pillow fits and provides a firm and stable support.

The sheets (8a) and (8b) are integrally formed by bonding. In addition, one piece of the height-adjusting non-membrane urethane foam (9) is inserted, and the one shown in FIG. 4 is obtained by inserting two pieces of the height-adjusting non-membrane urethane (1).

The bag (7) is a three-dimensionally structured three-dimensionally connected knitted fabric (5) having an air permeability on the upper surface side, which is connected to a ground structure composed of multifilament yarns and a monofilament connecting yarn having moderate rigidity. It is a knitted fabric (illustration is omitted) and uses a knit made of cotton material on the lower side with a certain degree of elasticity. These two pieces are sewn into a bag shape and opened and closed on the back side of the pillow It has a zipper (6) that can be freely adjusted to allow the height adjustment non-membrane urethane foam (9) to be taken in and out, and the height of the pillow to be adjustable according to the user.

[0013]

According to the present invention, since a non-membrane urethane foam is used as a filler for the pillow and a knitted fabric (5) is used at least on the upper surface side of the bag body (1), air permeability is improved. Excellent, even if the hair after washing is on the floor in a semi-dry state, it radiates moisture efficiently, does not stuffy and does not accumulate moisture, so it does not breed insects or mold and is hygienic. ,
In addition, since the cushioning properties at the positions near the shoulders of the head and neck are softened, the foot can be supported from the head to the neck, firmly supported, and a good night's sleep can be achieved.

Further, since the materials constituting the pillow are all excellent in air permeability and well drained, they can be washed by a washing machine, can be washed at home, can be washed at home, and are very economical. It is a target.
