Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

SUMMARY OF THE INVENTION The present invention relates to a pillow containing beads which is excellent in breathability, moderate elasticity, conformability to form, etc., and further has a structure which is improved in sleep effect, hygiene, handling, etc. It is intended to provide a new pillow.

[0002]

2. Description of the Related Art It has been considered that insomnia can be resolved by ensuring a cold head and foot fever state during sleep and a good night's sleep can be achieved, which is extremely effective for maintaining and promoting daily health. By various methods, efforts have been made to achieve a sleeping condition with head and foot fever. A large number of cylindrical or tubular beads made of synthetic resin are enclosed in the pillow to improve the air permeability inside the pillow, and to provide appropriate elasticity and followability to the head. The fact that various types of pillows with beaded bodies are sold on the market and are favored by many people can be said to be one of the ways to increase the head cold effect among them,

The bead made of synthetic resin, which has been employed in the conventional beaded pillow, is made of a relatively soft and smooth surface such as polypropylene, for example, so that the beads come into contact with each other. The pillow shape can follow the shape of the head very easily even when the user turns over and changes his posture, and can also cause unpleasant noise. In addition, since a reasonable elasticity is secured as a whole by the innumerable spaces between the bead bodies and the material and hollow part of the bead body itself, they have recently been frequently used as pillow fillings. I have.

On the other hand, as another means for achieving a comfortable sleep, a magnet has recently been newly embedded in a necessary place,
Sleeping pillows that can be expected to have a magnetic effect, pillows called special anti-snoring pillows pursuing a special shape and structure effective for eliminating snoring, etc. In addition to health management, it also considers hygiene management, eliminating odors sticking to pillows, absorbing moisture such as sweat, and expecting negative ion effect and sterilization effect. The use of activated carbon directly as a core material of pillows has appeared, and pillows that can be used in a sanitary and healthy manner for a long time have been devised and put into practical use.

[0005] In the case of a pillow utilizing the material properties of this activated carbon, the activated carbon packed in the bag is usually used in the form of powder or granules. In particular, powdered activated carbon is of course used as well as granular activated carbon. However, activated carbon that has been rubbed and powdered during use leaks not only from the seams of the bag but also from the texture depending on the fabric, and other bedding such as sheets and nightclothes Therefore, in a pillow using activated carbon as a core material, it is technically very difficult to realize a pillow that achieves both good air permeability and safety in handling. Powdered or granular activated carbon has the disadvantage that when absorbed, it sticks to each other and hardens into a dango-like shape. Good sleep There was also disadvantage that shorten the period of time that can be secured.

The inventor of the present application has paid particular attention to a pillow made of activated carbon as a core material, and has started a trial production and an experiment of a pillow capable of resolving the technical problems and disadvantages as described above and enjoying only the advantages thereof. In spite of repeated failures, we have finally completed and commercialized a pillow with a completely new structure that can utilize activated carbon as a core material as described later. In the following, a detailed description will be added so as to clearly understand all the technical ideas of the pillows included in the present invention, with reference to the description of the embodiment representative of the present invention shown in the drawings as a clue. .

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As clearly understood from the embodiments of the present invention shown in the drawings, a pillow included in the present invention basically has the following configuration. That is, a granular or powdered activated carbon and a large number of bead bodies having a hollow portion capable of penetrating and holding the granular or powdered activated carbon in a breathable state are mixed in a gas-permeable bag. It is a filled pillow. In other words, if the expression is changed, a suitable amount of granules or powders is formed in a gas-permeable bag together with a large number of beads each having a hollow portion capable of penetrating and holding granular or powdery activated carbon in a breathable state. Activated carbon is made into a sealed shape, and most of the activated carbon that has been crushed or rubbed into the hollow portion of the bead body in the bag body is made into a holding shape, and the total surface area of the activated carbon that can be brought into contact with the space inside the bag band is obtained. The basic configuration of the pillow included in the present invention can be represented as a pillow characterized by suppressing a substantial decrease.

[0008] In addition, if the above-mentioned configuration is shown as a more specific one, it has a granular or powdered activated carbon, an opening through which the granular or powdered activated carbon can enter, and the opening of the opening. In the back, a large number of spherical bead bodies having a diameter larger than the opening and having a spherical hollow part formed to allow the above granular or powdered activated carbon to be held inside in a permeable state, The pillow is a mixture of pillows in a bag, which, like the basic structure described above, also has, in other words, a granular or powdered activated carbon inside a breathable bag. A hollow portion having a diameter larger than that of the opening and having a diameter larger than that of the opening and capable of holding granular or powdered activated carbon therein in a gas-permeable state. Many spheres formed Along with the beads, an appropriate amount of granular or powdered activated carbon is made into a sealed shape, and most of the activated carbon that has been crushed or rubbed into the hollow portion of the bead in the bag is made into a holding shape, and the space inside the bag band is formed. A pillow characterized by suppressing a substantial decrease in the total surface area of activated carbon that can be contacted.

Activated carbon is granular, that is, approximately 1 mm to
Activated carbon having a diameter of about 10 mm (the upper limit depends on the diameter of an opening to a hollow portion of a bead, which will be described later), and is particularly a uniform granular material having a diameter of about 2 to 5 mm. Is desirable, or in the form of powder,
Powders of 1 mm or less, especially about 0.1 mm, are suitable, and they are charcoal, wood sawdust, coconut shell, pulp waste liquid, lignin, coals (lignite, lignite, bituminous coal, anthracite), peat, pitch, What is formed from various known raw materials, such as petroleum coke and cellulose, is crushed and sieved to obtain predetermined granular or powdered activated carbon, and different materials can be used alone or in a mixture of several types. In addition, those having different particle sizes are used as an optimal ratio as needed, for example, a ratio of about 3 to 7 powdered activated carbon to about 7 to 3 granular activated carbon, and most preferably, a combination of about half and a half. You can also.

[0010] The bead body has a function of naturally accommodating and holding activated carbon in the internal hollow portion, and itself has
It must be capable of exhibiting the function as a core material of the pillow, that is, moderate elasticity, conformability to the shape, breathability, durability, friction noise elimination, etc., and there is no particular limitation on the overall external shape, for example, a single tube Rugby spheres, ball shapes, appropriately shaped tubes such as bent tubes and the like can be adopted, and in any case, even after being mixed in the bag with the powdered or granular activated carbon to be adopted, and formed into a sealed shape, It is necessary that the activated carbon in the form of powder or granules be formed into a structure that easily penetrates and is entrapped in the internal hollow portion.

Accordingly, the bead body is formed by finely cutting a resin pipe formed in a long pipe shape in advance, or a large number of bead bodies are formed at a time by a mold, and are connected to each other after the formation. It can be formed by separating and cutting the runner portions one by one, and the like.
It may be formed on the outer surface inclined in a tapered shape (conical shape, etc.), or may be formed in a shape in which only the inner hollow portion is formed in a tapered shape to enhance the holding effect of activated carbon. There is no problem.

The hollow portion of the bead body may have a straight shape, but preferably has an opening diameter such that after the activated carbon has penetrated into the inside, the activated carbon is held in a stable state as much as possible. The inside becomes a bulged hollow part which swells greatly, for example, a rugby ball or a bead body formed of a material having the same thickness as a sphere, or a short tube in appearance, and the material thickness The inner wall is formed by bulging the inner hollow part, etc., and the inner walls are also specially designed so that the activated carbon that has once invaded is held in a more stable state. In addition to a suitable holding structure, for example, an inner wall having irregularities such as fine grooves or forest-like projections formed thereon, or a flocked wall, a well-known adhesive (adhesiveness is maintained as long as possible) Hope Is applied to the inner wall surface, or formed on the inner wall surface by combining some advantageous holding structures such as a flocking structure in the uneven structure and an adhesive layer structure in the uneven structure. This can be very convenient.

The material of the bead body has at least the functions necessary for the core material of the pillow, such as, for example, appropriate elasticity, shape followability, air permeability, durability, friction noise elimination, etc. It is not particularly limited as long as it has all or some of the properties such as heat dissipation, antibacterial properties, weight reduction, and economy, and specifically, polyester, ABS, urethane foam, and the like. Synthetic resin, natural rubber, etc., or natural materials such as wood and bamboo, etc., and also relatively thin metal such as stainless steel, aluminum, titanium, etc., or ceramics Etc. can be appropriately selected and adopted alone or in combination of some.

The combination of the activated carbon and the beads may be used in an appropriate amount in each of the bags described later, that is, in an amount suitable for achieving the necessary amount of swelling of the bag required as a pillow. Activated carbon, for example, the amount of activated carbon controlled to about 50 to 100% of the volume of the bead body is separately sealed in a bag body, and then used and rubbed by being appropriately moved. Activated carbon crushed or crushed by collision, naturally penetrates into the hollow part of the bead body during the mixing process and realizes the pillow of the present invention, or in advance,
That is, before enclosing in a bag body, a predetermined amount of activated carbon and the bead body are mixed in a predetermined amount by a predetermined amount, rocked, agitated, etc. as appropriate and crushed, crushed, rubbed and horned. Then, the micronized activated carbon is infiltrated and held in advance in the hollow portion of the bead, or the activated carbon is forcibly formed into the hollow portion of the bead by appropriate means. Then, a part of the activated carbon was previously held in the hollow portion of the bead body,
It is realized by enclosing them in a bag again.

The bag is intended to maintain the appearance of the pillow, so long as it has a proper air permeability and strength.
Up to the cylindrical shape, both ends of which are to be closed by appropriate means are included, and cloths usually used for pillows, for example, cloths made of natural materials such as cotton and silk, and polyesters and the like All kinds of pillows that have been used for many years, such as those made of synthetic fibers or those made of knitted or braided reeds, wheat stalks, bark, etc., besides fabrics etc. using these blends It is possible to use a bag, and it is sufficient if the bag is made of a material and structure that is optimal for the target pillow. Hereinafter, some embodiments shown in the drawings will be described in detail so that the configuration of the pillow enclosing the above-described activated carbon and beads included in the present invention can be grasped more specifically and clearly. And
