The present invention relates to a pillow of charcoal plastic ball, and in particular, charcoal powder and nano so as to have a comfortable indoor environment and have a comfortable rest such as antibacterial and sterilization by charcoal, far infrared emission, and deodorization. Plastics containing silver of size are embedded in the pillows in the form of balls.

Generally, pillows act as cushions and rugs for people to lie down to relax in the spaces in which they live, usually pillowcases include cotton and cotton or grains (crude, sorghum, buckwheat, etc.), rice straw, fruit seeds (apricot, Wild peach). As such, when the pillow is made of cotton fabric, cotton, fruit seeds, etc., it does not have its own antibacterial and sterilizing function, so long-term use causes bad smell from cotton, cotton, and fruit seed materials. There is a problem that can cause the disease by moving the pathogen.

In the case of filling the pillow with charcoal, there is also a problem that charcoal powder leaks out and contaminates the surroundings or causes respiratory diseases of the user when the pillowcase is used as a nonwoven fabric packing material as follows.

Republic of Korea Utility Model Registration 20-0416291 has a charcoal sealed through the textile paper through the pillow, one side has an open insert so that the other side can be inserted, the other side is closed to form a pillow insert space, two or more separate buffer material It consists of a cushion pocket made of filling space and an outer skin made of fiber.

Korea Utility Model Registration 20-0278067 is a known pillow made of a pillowcase which is passed through a pillowcase for accommodating a pillowcase and covered with a pillowcase to prevent contamination of the pillowcase. They form a pillowcase made of breathable and dense tissue or synthetic fibers.

Korean Utility Model Registration 20-0278067 includes pillowcases that pass through pillowcases, and pillowcases that are covered with pillowcases to prevent contamination of the pillowcases. 55-65% by volume of buckwheat bran, and 2-4% by volume of dandelion to maintain the shape to prevent.

Republic of Korea Utility Model Registration 20-0416291; Korea Utility Model Registration 20-0278067; As the Korean Utility Model Registration 20-0278067, a pillow made by inserting charcoal directly into the pillow is suggested, but when the pillow is used, fine charcoal powder is counted between cotton and cotton, which can easily be contaminated or stained, which not only hurts the aesthetics but also adversely affects the human body. There is a number. In addition, when washing bedding, it is inconvenient to wash and difficult to use for a long time because the washing must be completely removed after the charcoal.

The present invention has been devised in view of the conventional problems as described above, the object of the present invention has the function of antibacterial and sterilization by charcoal, far-infrared emission, deodorization, reinforcing the sterilization effect by silver, fine charcoal To prevent the powder from leaking out

Charcoal powder having a particle size of 50 mesh ~ 1000 mesh (0.5mm ~ 0.025mm) is mixed with polyethylene or polypropylene resin at a weight ratio of 1 to 40%, and nano-size silver is mixed at a weight ratio of 1 to 5%. After extruding into pellets, the pellets are again punched through the injection molding to a size of 2 to 9 mm in the center of the sphere with a radius of 3 to 12 mm, and the surface is formed of engraved charcoal plastic balls. To provide a charcoal plastic ball pillow built into the charcoal plastic ball pillow.

Hereinafter, the charcoal plastic ball built-in pillow according to the present invention for achieving the above object will be described in more detail through the drawings and test examples.

1 is an exploded perspective view and enlarged view showing a charcoal plastic ball built-in pillow according to the present invention, a pillow made of a pillow case 10, a pillow case 20 and a pillow case embedded in the pillow case 20, polyethylene, Alternatively, the charcoal powder having a particle size of 50 mesh to 1000 mesh (0.5 mm to 0.025 mm) is mixed with polypropylene resin in a weight ratio of 1 to 40%, and nano-sized silver is mixed in a weight ratio of 1 to 5%. Through the pellet (Pellet) state, the pellet is again punched into the size of 2 ~ 9mm in the center portion of the sphere with a radius of 3 ~ 12mm through injection molding, charcoal plastic ball engraved on the surface It is formed of a 30, this charcoal plastic ball 30 is used as a pillow inner filling.

When manufacturing a pillow using the charcoal plastic ball 30, it is necessary to determine the size of the ball in order to eliminate the exhaust or the hardness by the charcoal plastic ball (30). According to the test example of the present invention, it is preferable that the size of the charcoal plastic ball 30 has a radius of 3 to 12 mm spherical shape for convenience of touch and production.

Charcoal powder having a particle size of 50 mesh to 1000 mesh is mixed with polyethylene or polypropylene resin at a weight ratio of 1 to 40%, and nano-sized silver is mixed at a weight ratio of 1 to 5%, and then extruded blending pellets (Pellet) is a continuous operation that can only be extruded conditions, it can not punch the pellet chip, it is impossible to control the weighing. If it is used as a pillow, a large pillow has a disadvantage of being uncomfortable to handle in a bedroom, such as a sag phenomenon and a bed because the material of the pillow case 20 is nonwoven. In order to improve this problem, it is possible to manufacture a mold in the shape desired by the user when the process is processed using the injection molding method, so that the injection molded charcoal plastic ball 30 according to the shape of the age group or the pillow in consideration of the weight and shape can be produced. have.

In order to increase the surface area of the ball so that silver and char are more exposed to the surface in order to increase the efficacy of the silver and charcoal contained in the charcoal plastic ball 30, the perforation 40 and the engraving during the injection molding in the charcoal plastic ball mold To form. The perforation 40 is a method of penetrating the center of the ball, the intaglio forms the surface of the ball in an uneven shape.

Charcoal in the present invention is a kind of activated carbon obtained by carbonizing oak, bamboo, pine, etc., and the surface area of internal pores is very large.

Adding nano-sized silver in this design has antibacterial and bactericidal action of charcoal, but it is not safe from sweat, saliva, and moisture. It is to.

As such, the charcoal plastic ball pillow of the present invention can remove the odor that may occur in the conventional bedding by using charcoal plastic ball having deodorization and purification, far infrared ray emission as well as antibacterial and bactericidal action, The powder does not leak out and contaminate the surroundings, thereby inhibiting the propagation of bacteria that carry pathogens that cause the respiratory disease of the user, and has an effect of smoothing the human body's biorhythm by far-infrared emission. And the charcoal plastic ball has the advantage of easy to clean the bedding and durable because it maintains the function of the charcoal even when washing together without being separated when washing bedding. In addition, the charcoal plastic ball of the present invention can be used as a filling material for bedding, such as bed mats, electric mats, and bedsore beds for patients, which were restricted due to their weight, as well as those used in a pillow. Applicable in shape form.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made within the spirit and scope of the present invention, and such changes or modifications are attached to the accompanying drawings. It should be included in the utility model registration claim.
