Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing accidental ingestion which prevents an accidental swallowing when an infant swallows a small article such as a small toy.

[0002]

BACKGROUND OF THE INVENTION Accidents due to accidental ingestion and ingestion are commonly found in infants. As a summary of accidents, intake routes by age group shown in FIG. 4 (April 1993-March 1994,
(Foundation) Japan Poison Information Center). This survey is data on poisoning received by the above information center from the general public in 1993, and it is clear from this data that there are overwhelmingly many oral accidents in infants under the age of five. Furthermore, according to the information center, when comparing age groups by causative substances, household products excluding pesticides and natural poisons,
It is also reported that infants under 5 years old account for 80% to 95% of accidents involving ingestion of pharmaceuticals, industrial supplies, and the like.

[0003] Conventionally, problems have been raised with regard to accidental ingestion and ingestion of infants. In the case of a liquid, a bitterness-emetic agent is added to the liquid to cause a feeling of bitterness when contained in the mouth, resulting in a feeling of vomiting. There is a method to prevent accidental ingestion, but in the case of shaped objects (particularly toys handled by infants), measures such as using paint that is safe to lick have been taken as a method to prevent accidental ingestion, but swallow it Active measures to prevent this are desired.

[0004]

SUMMARY OF THE INVENTION The present invention has been made under the above background, and provides a method for preventing accidental ingestion in a small article which causes bitterness when it is contained in the mouth to cause a vomiting sensation and prevents swallowing. The purpose is to

[0005]

In order to achieve the above-mentioned object, the method of preventing accidental ingestion in a small article of the present invention comprises a functional paint comprising a bitterness-emetic agent, a binder and a solvent. It is characterized in that a semi-penetrative film is formed on the surface of a small article.

[0006]

According to the above construction, when a functional paint is composed of a bitterness-emetic agent, a binder and a solvent, and the functional paint is attached to a small article and then dried to evaporate the solvent, the above-mentioned small size is produced. A semi-penetrative film is formed on the surface of the article in which a binder bitter emetic is adhered.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the method for preventing accidental ingestion of a small article according to the present invention, the small article will be described as a small toy.

In this method of preventing accidental eating, a functional paint is composed of a bitterness-emetic agent, a binder and a solvent, and a semi-penetrating film is formed on the surface of the toy with the functional paint. , A bitterness-emetic agent composed of denatonium benzoate (for example, BITREX (trademark) manufactured by McFarlane Smith Co., Ltd.) is used in a solution formed by diluting a toy material with a binder having good adhesiveness with a solvent (organic solvent). Good)
Is a melted product.

If the organic solvent is a hydrocarbon solvent, for example, pentane, hexane, heptane, petroleum ether, petroleum benzene, kerosene, cyclohexane, toluene, xylene, ethylbenzene, chloroform, methyl chloride, methylene chloride, tetrachloride. Carbon or the like may be used.

As the alcohol solvent, for example, methanol, ethanol, propanol, butanol, amyl alcohol or the like may be used, and as the ether solvent, for example, ethyl ether, butyl ether, isoamyl ether or the like may be used. Good.

Further, as the solvent for ketones, for example, acetone, methyl ethyl ketone, methyl isobutyl ketone, etc. may be used, and for the solvent for esters, for example, ethyl acetate, butyl acetate, etc. may be used.

The binder is selected to have good adhesiveness for each material of the toy. This binder is, for example, an acrylic resin-based binder when the material is styrene, ABS, polycarbonate, acrylic, or hard vinyl chloride, a vinyl chloride resin-based binder when it is soft vinyl chloride, and a chlorinated polypropylene resin-based binder when it is polypropylene. A binder may be used.

In the case of wood, a fibrin resin binder, an unsaturated polyester resin binder, an acid-curing aminoalkyd resin binder, a polyurethane resin binder, a vinyl butyral resin binder, a ceramic binder, and a nitrocellulose binder are used. You can use it.

In the case of metal or glass, an epoxy resin binder, a melamine resin binder, an aminoalkyd resin binder, an acrylic resin binder,
Silicon resin binder, phenol resin binder,
A urethane resin-based binder or an alkyd resin-based binder may be used.

The above binder may be a mixture of a plurality of binders depending on the material.

As shown in FIG. 1, the above-mentioned functional paint is
The binder 3 having a weight ratio of 3.6% and the bitterness-emetic agent 4 having a weight ratio of 0.4% were dissolved in the solvent 2 contained in the container 1, and the solid content (nonvolatile content) was 2 to 4 % Of a thin liquid functional coating, the toy 5 is dipped in the liquid functional coating, and then the solvent 2 is evaporated and dried by dip coating. 6 can be formed.

As a method for adhering the functional paint to the toy 5, spraying with a spray or the like, or application with a brush or the like may be used instead of dipping the toy in the functional paint.

If the toy 5 has a flat plate shape, as shown in FIG. 2, the functional paint is applied to the toy 5 through the space between the rollers 7 having the functional paint, and the semi-permeation is performed. It does not matter depending on the roll coating type for forming the film-like coating 6.

Then, the solvent 2 is evaporated and dried,
In order to form the semi-penetrative coating 6, drying at room temperature is basically performed, but if the material is a plastic material to accelerate the drying, it is dried at 60 to 70 degrees Celsius for 10 to 30 minutes. In the case of metal, it may be less than 150 degrees Celsius because of baking coating (the melting point of BITREX is 1 degree Celsius).
(Because it is 60 degrees or more).

The semi-penetrating film 6 is preferably formed to have a thickness of 2 to 3 microns. This is because the target article is a toy, which affects the color of the material, causes unnatural light reflections, and causes the toy to shine. However, if the surface of the material has fine work such as carving, unnecessary roundness will appear and the surface will be smooth, and the surface area of a small toy is 30 ~.
It is thought to be about 40 square centimeters, but in order to exert the vomiting effect while satisfying the above conditions such that safety can be ensured even if swallowed, appropriate values are repeatedly tested, and as a result, the above values are reached. It was done.

Since the semi-penetrating film 6 is formed as described above, as shown in the enlarged view of the semi-penetrating film in FIG.
When the semi-penetrative film 6 is formed on the material surface 5a of the toy 5, since the bitter emetics 4 are connected by the binder 3 and adhere to the material surface 5a of the toy 5 with the binder 3, the bitter emetic The agent 4 does not detach from the surface 5a of the material and does not adhere to the fingers, and even if the fingers are licked after playing with the toy 5, there is no bitterness, and troubles occur during normal use. There is nothing to do.

When the toy 5 having the semi-penetrative film 6 formed therein is contained in the mouth, the bitterness-emetic agent 4 melts into the mouth and makes the person feel bitterness, so that the vomiting effect can be exerted.

[0023]

[Effect] According to the present invention, since the bitterness-emetic agent is bound by the binder and adheres to the material surface of the toy, the emetic agent can be kept on the surface of the toy for a long period of time without being peeled off in normal use. In addition, it is possible to suppress unnecessary transfer of the emetic agent to the fingers when holding the toy, and minimize bitter troubles other than accidental eating. Then, when it is contained in the mouth, bitterness is felt to cause a feeling of vomiting, and it is possible to effectively prevent accidental ingestion.
