Hereinafter, embodiments relating to the present invention will be described in detail. The embodiments described below are specific examples preferable for implementing the present invention, and thus various technical limitations are made. However, the present invention is not limited to the following description. It is not limited to this form unless otherwise specified.

Since the pillow of the present invention is composed of a small number of members such as the main body portion 1 and the support portion 2, it can be manufactured in a small number of steps, and the time required for the manufacturing steps can be shortened.

The main body 1 is a member that serves as a base of the pillow, and is a member that directly or indirectly supports the head and neck of the user. As shown in FIG. 1, on the upper surface 1a, which is a surface of the main body 1 that faces the head and neck of the user, a curved portion 12 that is curved so as to be recessed in the lateral direction and supports the head of the user. It has a raised portion 13 that is smoothly connected from the curved portion 12 and supports the neck of the user. By providing the curved portion 12 and the raised portion 13 in this manner, the user's head and neck can be supported at a predetermined angle, so that the user's airway is less likely to be blocked and breathing is easier, so that the user can sleep comfortably. You can

The upper surface 1a of the main body 1 has a recess 11 having a predetermined depth extending from a part of the curved portion 12 to a part of the raised portion 13. As shown in FIG. 1, in the present embodiment, the concave portion 11 is provided in a U-shape from the curved portion 12 to the raised portion 13 in a plan view. The support portion 2 is fixed to the recess 11, and the main body portion 1 and the support portion 2 are integrated. Further, the upper surface 1a of the main body portion 1 is flat, that is, flush with the upper surface 2a of the support portion 2 without any substantial step.

The main body 1 is formed of only one type of elastic material. The elastic material is preferably, for example, soft foamable urethane. If the elastic material is foamable urethane, the pillow can be manufactured by pouring the raw material into the supporting portion 2 placed on a predetermined mold, so that the time required for the manufacturing process can be shortened. .. Also, if the elastic material is foamable urethane, it has a predetermined rebound resilience while deforming, so it stabilizes the head when it is appropriately depressed according to the weight of the user's head. Can be held.

The support portion 2 is a member that supports the head and neck of the user, and has a plurality of columnar through holes 21. Then, the support portion 2 is directly or indirectly fixed to the concave portion 11 of the main body portion 1.

The columnar through hole 21 is a hole formed in the support portion 2 along the thickness direction of the support portion 2. By providing the columnar through-holes 21 to secure a three-dimensional space in the support portion 2, the support portion 2 becomes breathable, and the user can sleep comfortably without being damp with the moisture emitted from the user's head or neck. be able to. Further, by providing the columnar through-holes 21, the load applied to the support portion 2 by the user's head or neck is dispersed, local loss of elasticity is prevented, the life of the support portion 2 is extended, and eventually the support portion 2 is extended. The life of the pillow can be extended. In the present embodiment, as shown in FIG. 1, the columnar through-hole 21 has a hexagonal shape and is provided in a honeycomb shape. Although the columnar through-holes 21 are hexagonal in this embodiment, they can be provided in a lattice shape as a quadrangle in other embodiments, or can be provided in another polygonal shape such as a triangle or an octagon, or a columnar shape, It may be provided as a shape having a curved outer circumference such as an elliptical shape.

The material of the support portion 2 is preferably an elastic material like the main body portion 1. When the user's head and neck are placed, the hardness is such that the columnar through-holes 21 are not crushed and completely closed in order to ensure the air permeability of the columnar through-holes 21. Since the head and the neck are not so deeply depressed that the user can hit the roll over easily, it is preferable that the head and neck are formed in a gel shape having a predetermined impact resilience. The support portion 2 preferably has a higher impact resilience than that of the main body portion 1 so that the user's head and neck portion do not sink too much and the user can easily turn over.

Specifically, the material of the support portion 2 is preferably a thermoplastic elastomer (TPE) such as styrene type, olefin/alkene type, vinyl chloride type, urethane type, ester type, amide type. When such a material is used, the support portion 2 can be formed by injection molding, and therefore, the processing can be performed quickly. If necessary, pigments, dyes, etc. may be added to these materials for coloring.

Further, in the support portion 2, a seat portion 22 provided so as to cover the plurality of columnar through holes 21 is fixedly provided on the bottom surface, that is, the surface on the main body portion 1 side. The seat portion 22 is preferably provided on the entire bottom surface of the support portion 2. When the pillow is manufactured, the seat portion 22 prevents the raw materials of the main body 1 from flowing into the columnar through holes 21 when the raw materials of the main body 1 are poured into the support portion 2 placed on a predetermined mold. Therefore, it is possible to secure the columnar through-hole 21 in its original shape. Further, the seat portion 22 allows the manufacturing method described in the description of the main body portion 1 to be adopted, and the time required for the manufacturing process can be shortened.

Further, it is preferable that the seat portion 22 has air permeability. Since the seat portion 22 has air permeability, it is possible to diffuse the water generated from the head or neck of the user to the body portion 1. In addition, as described above, when the raw material of the main body 1 is poured into the supporting portion 2 placed on a predetermined mold to manufacture, an air pocket is generated between the raw material of the main body 1 and the sheet portion 22. Since it is difficult, the raw material of the main body portion 1 and the sheet portion 22 can be brought into closer contact with each other, and the concave portion 11 of the main body portion 1 and the support portion 2 can be made difficult to peel off. Thus, the side surface of the support portion 2 is directly fixed to the wall surface of the concave portion 11 of the main body portion 1, and the bottom surface of the support portion 2 is indirectly fixed to the concave portion 11 of the main body portion 1 via the sheet portion 22. Will be done.

In order to provide the sheet portion 22 with air permeability, the sheet portion 22 is specifically a non-woven fabric or a woven fabric using a material such as polypropylene fiber, polyethylene fiber, polyester fiber, nylon fiber, cellulose fiber, or aramid fiber. It is preferably formed. The sheet portion 22 is fixed to the bottom surface of the support portion 2 by fixing means such as heat fusion or an adhesive.
