Description

SANITARY FINISHED STUFFED/PLUSH TOY AND ITS MANUFACTURING METHOD
BACKGROUND OF THE INVENTION Field of the Invention
This invention relates to a sanitary finished stuffed/ plush toy and the manufacturing method thereof, which provides sanitary condition for play by the infants and children. More particularly, the invention relates to the novel sanitary finished stuffed/ plush toy and the manufacturing method thereof, wherein the fabric materials are treated and affixed with the antibacterial chemical which is colorless, transparent and unharmful to the human body, and the raw material particles of the plastic projections which are used for an eye, nose, etc of the stuffed/ plush toy are treated with said antibacterial chemical, in order to maintain the semi-permanent antibacterial activity in whole even after washing.
Description of the Prior Art
A variety of microorganisms which directly effect human life are largely classified into the pathogenic (e.g., bacteria, fungi and yeast) and non- pathogenic types. In order to eliminate or eradicate the pathogenic microorganisms which are harmful to human, various methods of anti-bacterial chemicals are used. In particular, in parallel with the improvement of one's life in recent years, the better sanitary consciousness and intensive research thereto have been on the rise. Among other things, the antibacterial treatment has drawn a keen attention from the general public in that such treatment may help to prevent many of the contagious diseases induced by inhabitation and multiplication of the microorganisms in the environment.
Meanwhile, a stuffed/ plush toy which has been widely used at home and professional nursery institutes consists of polyester or acrylic fiber and plastic projection ornaments. Such stuffed/ plush toy is recognized as one of the favorite toys by children of less than 10 years of age, e.g., the infants ranging from 2 - 3 years of age. Unlike the adults with strong bacteria resistance, the infants with weak bacteria resistance is vulnerable to various pathogenic microorganisms which are present in the environment. The infants and children are in a direct contact with a toy, and the personal hygiene concerns may rise to the level of the life- threatening situation. As for a stuffed/ plush toy, it is commonly accepted that the detection process be undertaken to check the needle or metal in the sewing process based on the ongoing inspection on general safety. Nevertheless, under the situation where infants are apt to suck all things by mouth, the conventional stuffed/ plush toy with no antibacterial treatment is vulnerable to infiltration of general microorganisms which are present in the plastic molding ornaments such as eye, nose in addition to the fibers therein. Furthermore, the human saliva smeared onto the stuffed/ plush toy may promote the unsanitary conditions for proliferation of microorganisms. In this context, there is an urgent need for improvement in the aforementioned unsanitary conditions. As such, the conventional stuffed/ plush toy has disadvantages in that in spite of the fact that the end-users of a toy is limited to infants and children whose resistance to bacteria is extremely low, the conventional toy is not designed to prevent the growth of microorganisms. On the contrary, the suitable conditions for inhabitation of bacteria are endangering the sanitation of infants, thus necessitating the proper antibacterial treatment. In this context, there is an urgent need for the antibacterial treatment which is unharmful and can sustain antibacterial activity even after washing. SUMMARY OF THE INVENTION
Therefore, the object of this invention is to provide a sanitary finished stuffed/ plush toy and the manufacturing method thereof, wherein each of the antibacterial treatment using unharmful anti-bacterial chemical is applied to the fabric and plastic molding ornament materials. Thereafter, the toy is able to sustain antibacterial activity even after washing, thus optimizing the safety conditions where infants and children can play with the toy under the sanitary environment.
Detailed Description of the Invention
This invention relates to a sanitary finished stuffed/ plush toy comprising plastic molding ornaments and fabric materials, wherein said plastic molding undergoes an antibacterial treatment while in the projection- molding state by means of mixing a -phosphate zirconium having ion- exchanged silver ion prior to projection, and said fabric materials are fixated with cationic quaternary ammonium chloride.
Further, this invention includes a process of manufacturing a sanitary finished stuffed/ plush toy comprising of plastic molding ornaments and fabric materials, wherein: the plastic projection molding ornaments are fabricated in such a manner that -phosphate zirconium having ion-exchanged silver-ion is added to the raw materials prior to projection and mixed at 200 ~ 270 °C, the mixture of which undergoes a projection molding; said antibacterial-treated plastic ornaments and fabric materials are assembled by a common sewing method to manufacture a toy; a stuffed/ plush toy is dipped or padded in cationic quaternary ammonium chloride for the antibacterial treatment, after which is dried; and the air is fluxed onto a toy at 110 ~ 120 °C in order to ensure the homogenous state with the toy fiber and fixation of the antibacterial chemical onto a toy. This invention is explained in more detail as set forth hereunder. This invention relates to a stuffed/ plush toy having a semi-permanent antibacterial activity, wherein the molding process of the plastic ornaments is carried, and the toy is thus assembled, after which the toy fiber is treated and fixated with an antibacterial chemical containing appropriate amounts of components. The plastic molding ornaments of this invention are used for the fabrication of a toy, e.g., for making an eye and nose of a doll. For example, the raw materials of this invention include some generally-used resins such as polystyrene, and ABS. The antibacterial treatment is carried out in such a manner that prior to the projection molding process, the antibacterial chemical is added to the raw materials for mixing therein. The sequential steps of such antibacterial treatment are explained as set forth hereunder.
First, the particles of raw material is placed onto a melting jar and dissolved by heating at 200 ~ 230 °C for 10 ~ 30 minutes. a -phosphate zirconium having ion-exchanged silver-ion (MZr2(P0 )3 • yH20, where, M is Na, and 0 ≤ y ≤ 2), the antibacterial chemical, is added to this solution. The antibacterial chemical was added in the ratio of 0.1 ~ 1 wt % in proportion to the particles of raw materials and mixed homogeneously at the constant temperature of 240 ~ 270 °C for 10 ~ 40 minutes. The antibacterial effects of the antibacterial chemical can be observed via cell membrane destruction associated with the bactericidal action of the antibacterial metal ions and active oxygen. If the amount of the antibacterial chemical is extremely small, the bactericidal effect is negligible, but the excessive amount thereof affects the chemical composition of the resin, thus inducing much difficulty in the molding process of a toy.
Then, for fixating the antibacterial chemical, so added, to the raw materials, the reacting solution was again mixed at 210 ~ 230 °C for 5 - 20 minutes and welled up to fabricate the molded doll shape such as eye, nose, etc. using a projector. The molding doll shape was cooled, followed by the molding process to manufacture the plastic molding ornaments under such antibacterial treatment.
With the plastic molding product, so treated with the antibacterial chemical, the stuffed/ plush toy derived from fabric materials is manufactured by a commonly available process. Then, the antibacterial treatment is directly applied to the toy. The antibacterial treatment for a toy fiber is performed as follows:
According to this invention, the antibacterial chemicals designed for the antibacterial treatment of a toy fiber include colorless, transparent water- soluble cationic quaternary ammonium chloride so as not to affect the color of a toy, and such cationic quaternary ammonium chloride of 1.5% (pH 6 ~ 7) is employed in the ratio of 3 ~ 7 wt % in proportion to the weight of a toy. If the amount of the antibacterial chemical is extremely small, the antibacterial effect is low and incessant, but the excessive amount thereof will affect the appearance of the fabric materials.
The cationic quaternary ammonium chloride used for this invention may be selected from the group consisting of the formaldehyde group, chloride, phenol, alcohol, iodine, epoxide, and compounds containing silver ion.
The formulation of the antibacterial-treatment solution derived from the antibacterial chemical is made available in such a manner that the volumetric ratio of water to a toy in the antibacterial-treatment solution is 30 : 1, and such solution may be applied to the toy by means of the methods of dipping, padding or spraying. According to this invention, the antibacterial chemical may be applied to a toy in an appropriate method depending on the materials' characteristics, shape and pile length. For example, the dipping method is suitable for a hairless stuffed/ plush toy with light weight such as Nylex. The padding method is appropriate for a doll with adequate thickness and length. The spraying method is suitable for a Hipile toy with long hair and heavy weight. The dipping method is performed in such a manner that the basic cloth of a toy is coiled to a round beam and dipped at 30 ~ 50 °C for 3 ~ 10 minutes into the dipping bath of the antibacterial-treatment solution. The padding method is performed in such a manner that the basic cloth of a toy is coiled to a round beam, and the antibacterial-treatment solution is applied via the surface of beam to a toy at room temperature of 1 ~ 5 minutes. The spraying method is performed in such a manner that the basic cloth of toy is placed on a plain floor, and the antibacterial-treatment solution is directly sprayed onto a toy. According to this invention, the reason for raising the temperature of the dipping bath for the dipping method is that the antibacterial metal ions shows activation at such temperature.
For the purpose of adherence of the antibacterial chemical after completion of the antibacterial-treatment, the air is fluxed onto the dried toy at 100 - 120 °C for 1 ~ 5 minutes in order to ensure a homogeneous fabric toy. Hence, since the air flow at a high temperature may enhance the penetration power of textile via capillary phenomenon, the antibacterial activity is sustained even after washing of a toy.
The following examples illustrate various aspects of this invention but are not to be construed to limit the claims in any manner whatsoever.

The antibacterial chemical was added in the ratio of 0.5 wt % in proportion to the particles of ABS raw material and mixed homogeneously at the constant temperature of 250 °C for 25 minutes.
Then, for fixating the antibacterial chemical, so added, to the raw materials, the reacting solution was again mixed at 220 °C for 10 minutes and welled up to fabricate a molding doll shape such as eye, nose, etc. using a projector. The molded doll shape was cooled, followed by the molding process to manufacture the plastic molding product with such antibacterial treatment.
