Abstract

(57) [Problem] To provide a pillow capable of engaging with irregularities around a head, a neck, and a shoulder in an ideal state, having excellent air permeability, and enhancing body temperature and sweat-dissipating power. A lower body made of urethane foam and an upper body made of a low-rebound resilience foam are provided on an upper surface of the lower body.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a pillow, and more particularly, to a pillow having improved fit around the neck and shoulders and also having excellent air permeability.

[0002]

[Prior art]

 Urethane foam, which has been widely used as a material in pillows, has the advantages of light weight and excellent cushioning. In addition, since it is easy to process and suitable for mass production, it has the advantage that it can be manufactured and sold at low cost.

[0003] Recently, a low-rebound elastic foam having characteristics of low rebound resilience and high elongation and compressive residual strain has also been used as a material for a pillow. Pillows made of this low-elasticity foam are ideally engaged with the irregularities around the head, neck and shoulders to keep the neck and spine in their original natural state, providing comfortable sleep. be able to.

[0004]

[Problems to be solved by the invention]

 However, conventional pillows made of general-purpose urethane foam have excellent cushioning and breathability, but due to their high rebound resilience, there is a strong sense of pressure on the convex parts of the head and shoulders, and a comfortable sleep can be obtained. Did not.

On the other hand, low resilience foam is ideally engaged with the irregularities of the human body, but has a higher material density than ordinary urethane foam, and therefore has poor air permeability, and has a low body temperature and sweat-dissipating power. Had the problem of being inferior.

[0006] In view of the above, an object of the present invention is to engage with irregularities around the head, neck and shoulders in an ideal state, and at the same time, have excellent air permeability, and enhance body temperature and sweat wicking power. It is to provide a pillow that can work.

[0007]

[Means for Solving the Problems]

In order to achieve the above object, the pillow of the present invention is characterized by comprising a lower body made of a highly foamed foam, and an upper body made of a medium foamed foam provided on an upper surface of the lower body. Is what you do. Here, the high foamed foam and the medium foamed foam have an apparent density of 0.1 g / cm ³ or less (gas / solid ratio of 9 or less), respectively. 1 to 0.4 g / cm ³ (gas / solid ratio of 1.5 to 9). Further, the expansion ratio 3-4 fold (apparent density 0.3 g / cm ³ before and after) as a boundary, low foaming it less (or high density), even if classified as high expansion (or low density) foam more is there.

In the present invention, by using a medium foamed foam for the upper body constituting the pillow, it is ideally engaged with the unevenness around the head, neck and shoulders of the human body, and the neck and spine are in their natural state. To achieve a comfortable sleep. In addition, since the lower body is made of a highly foamed foam, the effect of improving the cushioning property and the shape retaining force can be obtained at the same time.

In the pillow of the present invention, it is preferable that the upper body has a through hole in a height direction.

[0010] By forming a through hole in the height direction in the upper body, body temperature and perspiration can be made good, and introduction of outside air becomes easy, so that excellent air permeability can be obtained.

It is preferable that the upper body is formed in a curved shape.

By forming the upper body in a curved shape, a gap generated around the neck can be eliminated, and the fitting property can be further improved.

[0013]

[Embodiment of the invention]

 Hereinafter, an embodiment of the pillow of the present invention will be described with reference to the drawings. FIG. 1 shows an overall perspective view of an example of the pillow of the present invention. As shown, the pillow 1 of the present invention includes a lower body 2 and an upper body 3 provided on the upper surface of the lower body 2. At the time of use, the periphery of the pillow 1 can be covered with a cover (not shown) or the like.

Since the lower body 2 is formed of a highly foamed (soft) foam that is widely used for mattresses, sheets, and the like, it has both moderate cushioning properties and excellent air permeability. The lower body 2 can flexibly receive the weight of the head and can also obtain an effect of preventing stuffiness, so that a comfortable sleeping comfort can be realized during use. The joining of the lower body 2 and the upper body 3 may be performed by, for example, an adhesive means such as an adhesive, and is not particularly limited.

The upper body 3 is formed of a medium foamed foam. Medium foamed foam is also called low resilience foam and is generally used as a packaging material for electrical components.It has low rebound resilience and high density, hardness, elongation and high compression set. . In the present invention, the upper body 3 to which the head is actually in close contact during use is formed of such a medium-foamed foam, so that the elastic resistance to the head is reduced, and there is no feeling of pressure from the pillow and it is comfortable. It can give a feeling of use. The high-foaming foam and the medium-foaming foam which can be used in the present invention include, for example, urethane foam.

It is preferable that a plurality of through holes 4 are formed in the upper body 3 in the height direction of the pillow 1. For example, as shown in FIGS. 1 to 3, the through holes 4 can be formed in a cylindrical shape and provided at equal intervals in the vertical and horizontal directions in a horizontal plane. The quantity to be performed is not particularly limited. FIG. 2 is a side sectional view of the pillow 1 of the present invention, and FIG. 3 is a front sectional view thereof.

In the present invention, it is preferable that the outer surface of the upper body 3 is formed in a curved shape. As shown in FIGS. 1 and 2, a gentle mountain-shaped curved convex portion 5 is formed on one side in the longitudinal direction of the upper body 3, so that when lying down, the curved convex portion 5 extends from the nape to the shoulder. It engages well with the recess around the neck and holds the neck and spine in the correct state with an appropriate force, so that a comfortable sleep can be achieved.

Next, an example of using the pillow of the present invention will be described with reference to FIG. FIG. 4 is a cross-sectional view illustrating a use state of the pillow of the present invention. When using the pillow of the present invention, the head is placed so that the concave portion around the neck engages with the curved convex portion 5 of the upper body 3 as shown in the figure. In the present invention, at this time, the upper body 3 made of a medium foamed foam is deformed so that no gaps are formed in the unevenness of the neck, shoulder, and head, so that the upper body 3 fits the human body properly. It does not give a sense of oppression.

As shown in the figure, the body temperature a radiated from around the head and neck while sleeping is radiated from the lower body 2 to the outside through the through holes 4, while the outside air b is radiated from the lower body 2 In order to easily reach the human body through the through-hole 4, air permeability around the head and neck at the time of going to bed can be improved, and it is possible to prevent stuffiness and give a comfortable feeling of use.

[0020]

[Effect of the invention]

 As described above, the pillow of the present invention has the following effects by adopting the above-described configuration.

[0021] By using the middle foamed foam for the upper body, the pillow is ideally engaged with the irregularities around the head, neck and shoulders, and the neck and spine are kept in a correct state to achieve a comfortable sleep. I can do it. In addition, the high foamed foam of the lower body can improve cushioning and shape retention.

Further, by forming a through hole in the upper body in the height direction, it becomes easy to diffuse body temperature, sweat, and outside air, and it is possible to obtain excellent air permeability.

Further, by forming the upper body in a curved shape, the gap generated around the neck can be eliminated, and the fit to the human body can be further improved.
