Description

Breathable filler

The present invention relates to a filling material which can be used as a pillow core in a pillow or as a mattress and a cover bed cover.

At present, the more common pillows are silk pillows, latex pillows, sponge pillows, 3D mesh pillows and other pillow cores. Among them, the latex pillow is soft and comfortable; the sponge pillow has a very good pressure-lowering function; the 3D mesh pillow has excellent ventilation function and is easy to wash and dry. But at the same time, each has its own shortcomings: latex pillows and sponge pillows are difficult to breathe, making people feel hot, although many businesses use punching technology to make a lot of round holes in the pillow, but when people sleep on the pillow, there is no punching. The place is still airtight, and after the pillow is compressed by the head, the mesh is mostly blocked and cannot be breathable; the 3D mesh pillow has high permeability, but because the mesh has a certain hardness, when it is pressed by the head, A large amount of noise is generated. If the density of the mesh is adjusted to decrease, the rigidity is lowered and the appropriate supporting force is lost. In addition, the mesh fiber of the 3D mesh pillow has a high hardness, which also causes a poor touch on the surface of the pillow. Therefore, the current pillow and pillow core are difficult to balance in the use of better breathability and pillow comfort.

One of the aims of the present invention is to provide a breathable and comfortable pillow core which is intended to provide high breathability and good comfort.

In order to achieve the above and other objects, the present invention provides a gas permeable filler comprising an inner layer and an outer layer. The inner layer has a top surface, a bottom surface and a circumferential surface connected between the top surface and the bottom surface, the inner layer is a three-dimensional fabric layer, and the outer layer surrounds the inner layer along the circumferential surface, the outer layer has a higher than the outer layer a projection of the top surface, the projection extending to cover at least a partial periphery of the top surface, the outer layer being a soft structural material.

Based on the above design, the present invention provides a gas permeable filler material which can be used to provide a good gas permeable effect by the inner layer of the bulge from the center to the outside, and the outer layer provides support and soft touch from the periphery of the inner layer and around the top surface.

In this embodiment, the inner layer 10 has a top surface 11, a bottom surface 12, and a plurality of elastic fiber lines located between the top and bottom surfaces 11, 12, and the elastic fiber lines are preferably arranged in an "X" shape and are hollowed out. The gas permeable structure has a top and bottom surface and a plurality of meshes, so that the inner layer 10 has excellent gas permeability and water washability. Since the elastic fiber lines between the top and bottom surfaces 11 and 12 may be chaotically stacked or staggered with each other, the top and bottom surfaces 11 and 12 do not necessarily have a solid peripheral surface, but the top and bottom surfaces 11 and 12 The elastic fiber line between them is still substantially confined within the range surrounded by the circumference of the top and bottom surfaces 11, 12, and is visually and conceptually considered to be between the periphery of the top surface 11 and the periphery of the bottom surface 12. 13 in a week.

The outer layer 20 surrounds the inner layer 10 along the peripheral surface 13. The outer layer 20 has a protrusion 21 higher than the top surface and a bottom portion 22 lower than the bottom surface. The protrusion 21 extends higher than the inner layer 10 and is surrounded by the inner layer 10. The inner periphery extends to cover the periphery of the top surface 11. Preferably, the protrusion 21 has a thickness in the vertical direction of less than 2 cm, and the bottom portion 22 extends lower than the inner layer 10 and extends into a complete rectangular block and adheres to the bottom surface of the inner layer. 12, the inner layer 10 is covered by the outer layer 20 and only the central partial top surface 10 is exposed by the opening in the center of the projection 21. The outer layer 20 is a soft structural material, and in particular, may be made of one or more of erect cotton, latex, silicone, foam or other soft material, and has soft and elastic recovery properties.

Referring to FIGS. 3 and 4, the outer layer 20 is covered on a part of the surface of the inner layer 10, so that the inner layer 10 is exposed only by the opening in the center of the protruding portion 21. In actual production, the outer layer 10 and the inner layer 10 may be firstly formed. The layers 20 are separately formed, and the outer layer 20 has a groove 23 having an outer shape corresponding to the inner layer 10 and partially shielded by the convex portion 21, and the inner layer 10 is placed in the groove 23 in the vertical direction y, due to the inner layer 10 and The outer layer 20 has elasticity. When the inner layer 10 is placed into the groove 23, the protrusion 21 can be pressed outward or the inner layer 10 can be compressed inwardly so that the inner layer 10 can pass through the opening in the center of the protrusion 21. After the inner layer 10 is placed, the inner layer 10 and the protruding portion 21 are released, and the inner layer 10 and the protruding portion 21 are automatically restored to complete the manufacturing process. Since the inner layer 10 has elastic fiber strands, the elastic fiber strands partially located on the peripheral surface 13 are inserted into the outer layer 20 after the completion of fabrication, and the inner layer 10 is tightly bonded to the outer layer 20. In the above embodiment, the projection covers the entire circumference of the top surface of the inner layer, however, it is also possible if the projection only covers a partial circumference of the top surface.

In view of the above, the present invention provides a breathable filling material which can be used as a pillow core or a mattress. When the user sleeps, since the inner layer 10 is outwardly contacted by the opening in the center of the protruding portion 21, the inner layer 10 can be provided with ventilation. The outer layer is coated on a part of the surface of the inner layer, especially the inner surface of the inner layer, so as to avoid the excessive hardness of the elastic fiber in the inner layer and affect the surface touch, and the outer layer provides a soft and soft touch.

Secondly, since the inner layer and the outer layer are respectively a three-dimensional fabric layer and a soft structural material, different softness and elasticity can be adjusted through design selection, and the user can provide a soft touch and an elastic supporting force when the user sleeps, thereby improving the use effect. Design freedom of the pillow or mattress.
