2. Description of the Related Art As a deodorant using a solid chlorine agent, Japanese Unexamined Patent Publications Nos. 4-45186 and 4-158802 disclose a urea stone formed into a sheet by kneading a chlorinated isocyanuric acid compound with a synthetic resin. Inhibitors and insoles for shoes have been proposed.

[0003] Japanese Utility Model Publication No. 63-14954 proposes a mat-like bath water treatment device in which a solid agent that releases active chlorine is incorporated in a water-permeable sheet that is used by being suspended in water in a bathtub. Japanese Utility Model Application Laid-Open No. 2-10847 discloses a sterilizing and deodorizing gas generator in which a solid chlorine agent is spread on the surface of a nonwoven fabric in the atmosphere using an adhesive.

A sheet obtained by kneading a synthetic resin with a solid chlorine agent is unsuitable for industrial production because the solid chlorine agent is decomposed when both are heated and kneaded, and the solid chlorine agent is contained inside the synthetic resin. Release of active chlorine is not performed smoothly. What spread solid chlorine agent on nonwoven fabric
Since the drug collapses, it is difficult to handle and has not been put to practical use.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a solid material which is suitable for deodorizing or disinfecting waste containers and the like and for disinfecting and disinfecting water in a small-capacity container. It is to provide a chlorine agent holding body.

[0006]

Means for Solving the Problems In view of such circumstances, the present inventors have made intensive studies, and as a result, have used a nonwoven fabric 1 having a bonding surface at an appropriate interval between dents.
The solid chlorine agent 2 is filled in a space formed between the sealing material 3 and the sealing material 3 to join the bonding surface of the nonwoven fabric and the sealing material.
The present invention was completed by forming an adhesive layer 4 on the outer surface of the substrate and spreading a release paper 5 on the outer surface of the pressure-sensitive adhesive layer 4 to obtain a desired solid chlorine agent holding body.

[0007] Typical non-woven fabrics used in the practice of the present invention are polyolefin fibers, polyester fibers, and the like. These non-woven fabrics have a size of about 1 to 10 mm between recesses in order to join a sealing material. This is one in which a joining surface having a width is provided and a plurality of recesses are formed. It is to be noted that the size of the formed dent is suitably a capacity capable of filling about 1 to 20 g of the solid drug.

[0008] Typical examples of solid chlorine agents suitable for the practice of the present invention are powdered or granular trichloroisocyanuric acid, sodium dichloroisocyanurate, potassium dichloroisocyanurate and highly bleached powder.

[0009] Typical pressure-sensitive adhesives suitable for the practice of the present invention include acrylic pressure-sensitive adhesives, rubber pressure-sensitive adhesives, and silicone pressure-sensitive adhesives. Therefore, an acrylic pressure-sensitive adhesive is preferable.

In order to manufacture the solid chlorine agent holding body of the present invention, a non-woven fabric having a bonding surface at an appropriate interval between the recesses is formed using a mold, and an acrylic or non-woven fabric is formed on one surface of the release paper. Prepare a sealing material coated with a rubber-based adhesive,
A plurality of recesses of the nonwoven fabric may be filled with a powdered or granular solid chlorine agent, an adhesive may be applied to the smooth surface of the nonwoven fabric or the opposite surface of the sealing material, and the nonwoven fabric and the sealing material may be pressed. Further, the nonwoven fabric and the sealing material can be joined by a method using high frequency welding.

In practicing the present invention, when a sealing material having an adhesive layer provided only on one side is used, and an adhesive is applied to the other side and bonded to a nonwoven fabric, a sealing material having an adhesive layer on both sides is used. It can be manufactured at lower cost than the method.
A perforation may be formed at the joint between the nonwoven fabric and the sealing material.

When this product is used for a container for solid waste disposal, the joint between the nonwoven fabric and the sealing material is cut to an appropriate size, the release paper of the sealing material is peeled off and attached to the inner wall or the inner surface of the lid. Just attach it. For use in a liquid container, it is similarly adhered below the liquid level of the container.

[0013]

According to the present invention, the solid chlorine agent is held in the recess of the non-woven fabric. Since the non-woven fabric is breathable, when used in the atmosphere, the moisture in the air comes into contact with the solid chlorine agent to decompose the drug. To release active chlorine. In addition, when used in water, water comes into direct contact with the solid chlorine agent to dissolve the drug, and a high-concentration drug solution flows out through the nonwoven fabric, thereby performing the desired sterilization, disinfection, or deodorization.

【Example】

(Example 1) 50 cm × 50 cm in size polypropylene nonwoven sheet (1 m ² per weight 50 g) of [trade name:
Colchem sheet, manufactured by Nichiei Kogyo Co., Ltd.]
A plurality of recesses each having a size of 6 mm × a depth of 2 mm were formed so that the width of the joint was 2 mm.

On the other hand, high quality paper (weight 80 g per 1 m ² )
Of one side make a single-sided release paper having been subjected to release treatment with a silicone resin, an acrylic pressure-sensitive solution was coated and dried to 1 m ² per 30g to form a pressure-sensitive adhesive layer with a reverse roll coater to the release paper, Rayon non-woven fabric (1
(A weight of 14 g per m < ² >) was stacked and pressed to produce a sealing material having an adhesive layer on one surface.

Each recess of the non-woven fabric is filled with about 100 mg of granular sodium dichloroisocyanurate, and a sealing material obtained by applying a polyamide-based hot melt adhesive to the non-woven fabric of the sealing material is brought into contact with a joint of the non-woven fabric. The solid chlorine agent holders were adhered to each other, and the solid chlorine agent was independently sealed in each recess to obtain a solid chlorine agent holder.

(Example 2) The solid chlorinating agent holder obtained in Example 1 was cut so that the amount of the agent was about 1 g (corresponding to 10 filling parts), and this was kept at a temperature of 20 ° C. 100
The sample was placed in 0 cc of water and the change with time of the effective chlorine concentration released into the water was measured by an iodometry method while stirring. As a result, the effective chlorine concentration after about 10 minutes passed was 380 ppm, and the effective chlorine concentration after about 20 minutes passed was 600 ppm, and almost all of the SDIC was eluted. From this, it was found that sodium dichloroisocyanurate in the nonwoven fabric was gradually dissolved and flowed out of the holder.

(Example 3) The solid chlorinating agent holder obtained in Example 1 was cut so that the amount of the drug became about 2 g (filling part: 20 pieces), and this was cut into a 45-liter pail-shaped raw material. It was stuck inside the lid of a garbage container, and garbage from home was put in this container and left in a sunny place outdoors. When the lid of this container was opened periodically and the odor in the container was confirmed, odor in the container was hardly recognized until seven days had passed. On the 8th day, the solid chlorine agent holding body was taken out, placed in 1000 cc of water maintained at a temperature of 20 ° C., and the effective chlorine concentration released into the water was measured by an iodometry method with stirring.

(Example 4) The solid chlorine agent holder obtained in Example 1 was cut so that the amount of the drug became about 1 g (filling part: 10 pieces), and this was cut at the bottom of a paper diaper processing container. The used paper diapers were put in this container, and the container was left indoors. The next day, when the lid was opened and the odor in the container was confirmed, almost no odor was felt.

(Example 5) The solid chlorine agent holder obtained in Example 1 was cut so that the amount of the drug was about 1 g (filling portion: 10 pieces), and this was cut into a medical waste disposal container. After sticking inside the bag, waste was put into the inner bag.
The next day, when the available chlorine concentration in the water that had leaked into the bag was measured, it was 100 ppm.

(Example 6) The solid chlorinating agent holder obtained in Example 1 was cut so that the amount of the agent became about 0.3 g (filling part: equivalent to 3 pieces), and this was cut under the water surface inside the vase. Then, 500 cc of water and 5 g of sugar were put into a vase and stirred well. Rose cut flowers 5 just after harvest in this vase
As a comparative example, five similar roses were placed in a vase containing only water and observed.

Roses in a water-only vase have fallen in about 7 days, whereas roses in a vase to which the solid chlorine-containing carrier of the present invention has been applied can enjoy flowers for about 13 days. Was. In addition, when the vase was washed after the flowers were viewed, the inside of the vase containing only tap water had slime, but the inside of the vase to which the solid chlorinated agent holder of the present invention had been applied felt slick. I couldn't.
