Abstract

[Problem] To provide a pillow that is easy to fit to the head and neck as a pillow that is affordable and that can be easily fitted to the back and neck while maintaining appropriate deformation. SOLUTION: The upper and lower parts of the plate are round or oval and convex, and the center is made of foamed urethane with a core material. It was a pillow put in. When the head is put on, the polyester cotton shrinks under the load, but the foamed urethane, which is the core, fits the occipital region and the cervical spine to the pillow while maintaining an appropriate deformation.

Description

  The present invention relates to a pillow that easily fits from the head to the neck while maintaining appropriate deformation.

Pillows used at bedtime have the character of being a daily necessities and a favorite product, and many types of pillows are sold, and many patent applications have been filed.
Until now, natural bags such as rice husks, buckwheat husks, cotton, feathers, etc. have been used in cloth bags. Many are commercially available.

As for pillows, the word “Dr. Pillow” is also seen, and there are many opinions such as “It is better to be taller” or “No, lowerer is better”. However, what is generally said is that a pillow that is elastic and can maintain a predetermined height even if it is appropriately deformed and fits the back of the head and the cervical vertebra is preferred.

  Pillows containing rice husks, buckwheat husks, etc. have the advantage of being able to disperse the load when placed on the head, but they are prone to change in height and overall shape. It may not fit in the neck. In addition, pillows made of plastic cotton, etc., are elastic, but are greatly deformed and may not be able to maintain the specified height during use. May not fit in.

  In order to maintain this ideal holding form from the head to the neck as a prior art that has solved this problem and further improved it, the main body is made of high-density foam superfoam, and as a whole it is reversely inclined in the short direction of the pillow As a pillow that can maintain sleepiness not only in an upward posture but also in a horizontal orientation, a core layer made of high-resilience polyurethane foam with a high hardness is coated. A pillow having a surface layer made of polyurethane foam having a lower hardness than the core material layer, integrated at the both ends in the width direction of the core material layer, and a thin surface layer covering this portion (Patent Document 2) ), Pillow to laminate the polyurethane foam surface material, core and backing material in order to prevent the blood flow of the scalp and preventing the head from becoming dull (Patent Document 3), which has high hardness Core material layer, thick intermediate layer, place An inner member is manufactured by laminating an upper layer of a thickness of the inner member, and the outer member is wound around the outer periphery of the inner member. The pillow is easy to manufacture and can be manufactured at low cost. There are many applications.

In the above-described prior art, urethane foam is mainly used as a core material. However, the material used is expensive, and a lot of manpower is required for the manufacturing process, which may inevitably become an expensive pillow.

Pillows are daily necessities, but on the other hand, they are consumables, but are desired to be inexpensive. Therefore, as a pillow that easily fits the back and neck while maintaining moderate deformation, a foamed urethane bag with a shape that easily fits the head and neck is surrounded by polyester cotton and surrounded by polyester cotton. I devised a pillow.

  The problem to be solved by the present invention is to provide a pillow that is inexpensive and easy to fit on the head and neck.

  The first device is a pillow having a plate-like foamed urethane as a core material, surrounded by polyester cotton, and an outer fabric made of cloth.

The plate shape only represents a shape like a plate with a predetermined thickness, not a hard one like a wooden plate, but a flexible soft or semi-rigid foamed urethane with a plate shape It is a thing. The reason why polyester cotton is used is that cotton made of natural fibers is expensive, and inexpensive synthetic fibers are used to reduce the price. This is a pillow in which this plate-like soft or semi-rigid urethane foam is used as a core, and its periphery is surrounded by polyester cotton, which is put in a bag made of cloth.

Urethane foam is mainly composed of soft foamed urethane with continuous and regenerative air bubbles used for seat cushions and mattresses, hard foamed urethane with intermediate properties and closed cells used for heat insulation. There are semi-rigid foam urethanes intended for shock absorbers, but the ones used as pillow cores are soft or semi-rigid foam urethanes.

Subsequently, the second invention is the pillow according to claim 1, wherein the upper and lower parts of the plate shape are formed in a circular or elliptical convex shape, and the urethane foam having a flat recess in the central part is used as a core material. .

As shown in FIG. 1, the pillow is generally rectangular when viewed from the front, and is composed of sides parallel to both shoulders of a person who is facing up and sides parallel to the neck that is perpendicular to both sides. The direction parallel to the shoulder is the left-right direction, and the direction perpendicular to this is the up-down direction. The upper and lower parts of the plate are the upper and lower parts in the vertical direction perpendicular to the neck, the upper convex part is on the upper part of the head, the central flat recess is on the rear part of the head, and the lower convex part is on the lower convex part. The cervical spine is placed on top. Since the foamed urethane with elasticity is used as the core material, the shape of the foamed urethane can be maintained even when the polyester cotton contracts due to the weight of the head, so that the head and neck can fit the pillow.

Furthermore, the convex portions on the upper and lower sides can change the height of the convex shape according to the preference of the consumer. Furthermore, since they are circular or elliptical, they can be used without distinction between the front and back surfaces.

  In the first device, since the core material has a simple structure using urethane foam, an inexpensive pillow that can maintain an appropriate deformation can be provided. In the second device, the head and neck can be fitted to the pillow without discriminating between the front and back surfaces, and sleep can be invited.

FIG. 1 is a view showing a pillow and its right and left and up and down directions. FIG. 2 is a pillow having a plate-like foamed urethane as a core. FIG. 3 shows a pillow with a foamed urethane core at the upper and lower portions. FIG. 4 is a state diagram using the pillow of the present invention. FIG. 5 is a cross-sectional photograph of a prototype pillow.

Examples of the present invention are shown below.

    FIG. 1 is a photograph of the pillow 1 as a whole. In FIG. 2, plate-like foamed urethane is used as the core material 4, the periphery thereof is surrounded by polyester cotton 3, and the pillow 1 is placed in a bag of the outer fabric 2. 2A is a plan view, and FIG. 2B is a cross-sectional view taken along line AA ′.

  FIG. 3 shows a pillow 1 having a foamed urethane having a convex shape at the upper and lower portions and a core material 5. 3 (3) is a plan view, and FIG. 3 (4) is a cross-sectional view at BB ′. Since the upper and lower portions are convex 51, when the head is placed on the pillow 1, the back of the head and the neck can easily fit the pillow, and sleep can be invited. This state is shown in FIG.

The urethane foam is produced by a “slab” or “mold” process. In the slab, the urethane whose section is continuously fired into a square shape or the like is cut into a predetermined size, and in the mold, the foam is foamed in the mold to a predetermined shape and then taken out from the mold. The urethane foam used as the core material can be used regardless of the production method.

FIG. 5 is a cross-sectional photograph of a prototype pillow according to the present invention. In this prototype, soft foamed urethane with convex parts at the top and bottom was used as the core material. The foamed urethane core material having the convex portions at the upper and lower portions is not limited to this shape, and the height of the convex portions at the upper and lower portions can be changed and the size can be arbitrarily determined.

  Since the materials used are general and the manufacturing process is not time-consuming, demand can be expected because it is a pillow that can be provided at a low cost and is easy to fit in the back of the head and neck while maintaining moderate deformation. .
