Abstract

PURPOSE: To provide bedding contg. carbide so as not to allow the carbide to leak outside while the contact with the outdoor air is well maintained in order to effectively utilize the humidifying and gas adsorption effect possessed by the carbide. CONSTITUTION: Grains 1 of charcoal pulverized to a size of 2 to 6mm in diameter or length are uniformly incorporated at >=10% by volume into a thin urethane sheet 2 of a thickness of 5 to 20mm. This urethane sheet 2 is packed into a bag-shaped side fabric 4 in superposition on a packing blank 3 used as wadding for ordinary laying bedding.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to bedding which utilizes a humidity control and gas adsorption action due to the adsorption of carbides.

[0002]

2. Description of the Related Art Heretofore, in order to maintain a good environment such as at bedtime, attention has been paid to the adsorptive effect of carbon, and carbide has been used for health bedding and the like. For example, Japanese Patent Laid-Open No. 62-
In the health bedding disclosed in Japanese Patent No. 152406, the bedding is filled with charcoal such as charcoal or activated carbon for the purpose of adsorbing harmful gas or cations at a sleeping place, controlling humidity, or removing a bad odor. ing.

Further, in the pillow disclosed in Japanese Utility Model Laid-Open No. 6-21470, rods packed with small pieces of charcoal are arranged in parallel in a strip bag for the purpose of controlling humidity and adsorbing gas due to the adsorption of charcoal. It is configured by being fixed to.

[0004]

However, when charcoal such as charcoal or activated carbon is used for bedding, the char is made into fine pieces, powder or granules so as not to impair the flexibility of the bedding. It must be ensured that these fines do not leak out of the bedding during use. Therefore, as a result of enclosing it in a bag made of a highly airtight material that does not allow fine powder to leak, air permeability is impaired, and the charcoal / activated carbon adsorbing effect is not effectively utilized.

The present invention has been made to solve the above-mentioned problems, and in order to effectively utilize the humidity control and gas adsorption actions of carbides, while maintaining good contact with the outside air, It is an object of the present invention to provide bedding which contains carbide so as not to leak outside.

[0006]

In order to achieve this object, in the bedding of the present invention, a flexible sheet containing carbide is inserted between the bag-shaped side cloth and the filling material. .

The carbide may be formed in a granular form.

[0008]

According to the bedding of the present invention having the above-mentioned structure, the carbide having a porous structure, which is held by the sheet in the bedding, absorbs the moisture increased by the sweat generated by the human body of the user, Adsorbs harmful gases and cations.

Further, if the carbide is made granular, the absorption of moisture and the adsorption of harmful gases and cations are promoted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment in which the bedding of the present invention is applied to a bedding will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a sectional view of a bedclothing A with charcoal according to this embodiment. For easy understanding, this cross-sectional view is shown with a space provided between the urethane sheet 2, the filling material 3, and the side cloth 4, but this space does not actually exist,
The elements are in contact with each other. Diameter or length is 2mm
Charcoal grains as carbides crushed to ~ 6mm size 1
However, in a thin urethane sheet 2 with a thickness of 5 mm to 20 mm,
It is uniformly mixed in a volume ratio of 10% or more. As shown in FIG. 2, half or more of the charcoal particles 1 contained in the urethane sheet 2 are arranged so as to be exposed to the outside from the surface of the urethane sheet 2. The urethane sheet 2
Is a bag-shaped side cloth 4 made of cotton, synthetic fiber or the like, which is overlaid on the filling material 3 which is used as a futon of a normal bedding made of a material such as cotton or urethane.
It is packed inside.

Next, the bed linen A constructed as described above.
When the user sleeps with the inserted surface of the urethane sheet 2 on the upper side, the charcoal particles 1 exposed on the outer surface of the urethane sheet 2 come into contact with the outside air through the side cloth 4, The charcoal grain 1 absorbs the moisture that has increased due to sweating during sleep. In addition, toxic gases and cations contained in the air are also adsorbed.

A second embodiment in which the bedding of the present invention is embodied as a pillow will be described below with reference to FIG.

FIG. 3 is a sectional view of the charcoal-filled pillow B of this embodiment. For easy understanding, this cross-sectional view is shown with a space provided between the urethane sheet 12, the filling material 13, and the side cloth 14, but this space does not actually exist,
The elements are in contact with each other. Diameter or length is 2mm
Charcoal grains as carbides crushed to ~ 6mm size 1
1 is uniformly mixed in a thin urethane sheet 12 having a thickness of 5 mm to 20 mm by 10% or more in volume ratio. The urethane sheet 12 is made of buckwheat, panya, urethane,
Normal pillow filling material 1 made of plastic and other materials
3 is wrapped around and wrapped in a bag-shaped side cloth 14 made of cotton, synthetic fiber, or the like.

Next, when the user places his / her head on one of the upper and lower surfaces of the pillow B constructed as described above, the air that has entered from the outside through the side cloth 14 is exposed on the outer surface of the urethane sheet 12. Touching the charcoal particles 11 that are being formed, the charcoal particles 11 absorb the moisture that has increased due to perspiration during sleep. In addition, toxic gases and cations contained in the air are also adsorbed.

The present invention is not limited to the embodiments described in detail above, and various modifications can be made without departing from the spirit of the invention.

For example, in this embodiment, although the carbide is used in the form of particles, it may be in the form of powder. The powdery form further enhances the flexibility of the sheet.

Further, the sheet to be inserted into the bedclothes or the pillow may have a certain density to hold the carbide, and the carbide can be mixed in during molding,
Instead of urethane, a sheet of hard cotton or resin cotton may be used.

Further, in the embodiment of the bedclothes, the sheet is inserted only on the upper surface side, but it may be inserted on both upper and lower surfaces so that both upper and lower surfaces can be used. Further, like the pillow, a sheet may be wrapped around the filling material. on the other hand,
In the case of a pillow, the sheet may be inserted on one or both sides on which the head is placed.

[0020]

As is apparent from the above description, according to the bedding of the present invention, a sheet mixed with carbide is
Since it is arranged so that it barely touches the human body of the user through only one side cloth, due to the adsorption action of the carbide having a porous structure, the moisture caused by sweat emitted from the human body,
In addition to bad odors such as body odor, it is possible to adsorb harmful gases and cations in the air, and it is possible to provide a comfortable environment for using bedding.

Further, when the above-mentioned carbide is made into particles, there is an effect that air can penetrate deeper than the exposed surface to further promote the absorbing / adsorbing action.
