Abstract

PROBLEM TO BE SOLVED: To maintain a natural shape of a neck when sleeping and to prevent stiff shoulders etc. in a low-resilience urethane foam pillow, and to make it more hygienic and comfortable with a pillow cover.
SOLUTION: In a pillow made of low-resilience urethane foam, the cervical vertebra is placed on a gentle convex band, and hemispheres are formed on the left and right sides of the convex band because the neck does not bend excessively. A protruding portion and a vent hole were provided, and a pattern was applied to a pillowcase having water absorption.

Description

  The present invention relates to the shape of a pillow made of low-resilience urethane foam.

  Normal polyurethane foam material sinks only by weight, but low-resilience urethane foam is characterized by softening by sensing body temperature as well as body weight and sinking slowly according to the unevenness of the body. For this reason, mats and mats can be obtained because the shape changes according to the sleeping person's body shape and fits with the body to uniformly support the contact area, providing excellent body pressure dispersion performance and no burden on specific departments. It is used for pillows and is commercially available.

  Also, as a prior art, mats and pillows made of low-resilience urethane foam as a material and kept comfortable and comfortable to use (Patent Document 1), and a pillow made of low-resilience urethane foam as a material using silicone rubber for ventilation There are pillows (Patent Document 2) that have a good and comfortable feel, and low-rebound pillows (Patent Document 3) with a cooling function.

  However, the inventor had a question in the above-mentioned literature etc. that the characteristics of the low-resilience urethane foam may not be fully utilized. That is, when sleeping on the back, it was desirable that the spine and cervical vertebra should be in a straight line when viewed from the front of the body, and that the spine and cervical vertebra should have gentle curves when viewed from the side of the body. Therefore, in order to allow the cervical vertebra to get on the central part between the upper and lower sides of the pillow, the central line part of the pillow is provided with a bulge of a gentle convex band on the left and right sides, and the convex shape so that the neck does not bend extremely On the left and right of the swelled portion of the belt, hemispherical protrusions with ridges were provided.

On the other hand, the low-resilience urethane foam has poor air permeability, and further, due to its heat insulating properties, the head becomes muddy and sleepy. In addition, low-resilience urethane foam is difficult to wash with water. Therefore, a pillow cover that has a low-rebound urethane foam pillow with air holes penetrating the front and back and prevents dirt and absorbs sweat was also examined.

Furthermore, this one-piece pillow without a pillow cover looks like a woman's bust at first glance, and the pillow cover is devised not only with functions such as sweat absorption, but also with colors and patterns.

The problem to be solved by the present invention is that, in the foam foam pillow, the neck is kept in a natural shape while sleeping to prevent stiff shoulders, etc., and the pillow cover is hygienic and playful. .

In the pillow of the present invention, the shape of the raised portion of the cervical vertebra is the raised portion of the gentle band, and hemispherical protrusions are formed on the left and right of the raised portion of the convex band so that the neck does not bend excessively. It is provided.

That is, the invention of claim 1 is a pillow that is integrally molded from a low-resilience urethane foam, and has a gentle convex band swelled to the left and right of the center line between the upper and lower sides of the pillow, The pillow is characterized in that hemispherical protrusions are provided one by one on the left and right sides of the raised portion of the convex band shape at a predetermined interval from the central part between the left and right. Here, the top and bottom of the pillow refers to the direction from the head to the spine when the pillow is used, and the left and right refer to a direction perpendicular to the top and bottom. When lying on its back, the cervical vertebra is positioned higher than the spine and is provided with a convex raised portion to fit the cervical vertebra. The reason why hemispherical protrusions are provided on the left and right sides of the convex bulging part is that the neck does not bend extremely when sleeping. This is to prevent the hemispherical protrusion from bending the neck muscles extremely. In addition, the thickness of the pillow may be increased from the upper and lower sides of the pillow to the center thereof without causing the gentle convex belt to rise.

The invention according to claim 2 is the pillow according to claim 1, wherein a plurality of through holes are provided as ventilation holes from the back surface to the surface. The front surface of the pillow is the surface on which the head rides, and the reverse surface is the reverse surface. This is because the low-resilience urethane foam has poor air permeability, and its heat insulation prevents the head from being steamed in summer. This is because, in order to increase the air permeability, it is better to provide a large number of through-holes having a small diameter within a range that does not lose the characteristics of the low-resilience urethane foam.

The woven fabric, non-woven fabric, and polymer sheet The invention of claim 3 is the pillow according to claim 1 or 2, further comprising a pillow cover made of a water-absorbing woven fabric, non-woven fabric, polymer sheet, or moisture absorbing sheet. The low-resilience urethane foam is uncomfortable due to poor evaporation even when sweated, and it is difficult to wash with water as described above. Therefore, a pillow cover with good water absorption is necessary. Many woven fabrics, non-woven fabrics, polymer sheets or moisture-absorbing sheets with good water absorption are commercially available, and by using them as pillow covers, low-resilience urethane foam pillows can be comfortably prevented for a long period of time. Can be used.

There is a pillow cover of a three-layer structure material in which the first layer quickly absorbs moisture, the second layer quickly diffuses moisture, and the third layer blocks moisture. This is the pillow cover on the inside of the low-resilience urethane foam pillow, and because the shape of the low-resilience urethane foam pillow resembles a female bust, a water-absorbent woven fabric with a pattern such as a female blouse is used on the outside pillow cover It can also be.

  The low-resilience urethane foam pillow of the present invention prevents extreme bending of the neck when sleeping and cures the stiff shoulders. Furthermore, since the shape resembles a female bust, men can have a more comfortable sleep.

  The form for implementing this invention is shown below.

FIG. 5 is a photograph of the appearance of a low-resilience urethane foam pillow integrally molded according to the present invention. The front view, elevation view, and side view are shown in FIG. 1, FIG. 2, and FIG. The reason for the integration is that a mold having a shape based on the present invention was created and molded in one step.

The through-hole, which is a ventilation hole, was drilled after being integrally molded this time, but the through-hole can also be integrally molded with a mold. Although an example of the vent hole position is shown in FIG. 4, it is also possible to provide a vent hole on the entire pillow front. Further, the diameter of the air hole can be changed depending on the position of the air hole. For example, the diameter of the vent hole can be reduced as the vent hole is formed radially from the center of the front of the pillow and goes outward from the center.

A low resilience urethane foam pillow with a patterned pillow cover is shown in FIG. For men, it feels like they are sleeping with their heads on a woman's bust.

There are many pillows and mats on the market that take advantage of the characteristics of low-resilience urethane foam pillows. The present invention can be a popular goods.
