Description

  The present invention removes odors from living odors attached to the stuffed toy itself and bad odors caused by infants' saliva, sweat, tings, etc., and suppresses the generation of microorganisms such as bacteria, and also formsaldehyde, ammonia, and acetic acid in the air in the room. The present invention relates to a stuffed toy that can adsorb and remove bad odors such as hydrogen sulfide.

  Although stuffed animals are used as a toy for infants or as decorations for indoors throughout the year, they are difficult to wash and are often left as they are. It has been difficult and sanitary. In addition, a soft touch feeling is preferred for the stuffed skin material, and a fibrous napped fabric is often used. However, the napped fabric acts as an adsorbent and often absorbs bad odors of life. There is also a need for a technique for removing the odor adsorbed on the stuffed animal. In recent years, the airtightness of houses has been remarkably improved, and living odors are trapped in the room, so there is a growing interest in purifying indoor air, and stuffed toys that are indoors and are decorative items all year round. It is also required to clean the indoor air.

In order to cope with such a problem, Patent Document 1 discloses a technique for filling a fiber or foam mixed with a pest repellent as a stuffed stuffed animal. Patent Document 2 proposes a technique in which a deodorizing agent is built in a predetermined portion of the stuffed animal to remove a strange odor adhering to the stuffed animal and also deodorize the space where the stuffed animal is installed. These technologies support pest repellents and deodorizers on special fiber assemblies called stuffed animals, and are evaluated as exhibiting some deodorant effect and pest repellent effect. No technology has been developed to remove even the odors of living odors attached to the stuffed skin material itself and the odors of infants' saliva, sweat, and hand tingling.
