Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin abrasive used for cleaning pachinko balls, coins for gaming machines and the like.

[0002]

2. Description of the Related Art For example, used pachinko balls are collected to remove oil such as human oil, sweat, ash of cigarettes and fine dust adhering to the surface, and then to remove dirt such as minute dust. Returned to the rental machine. One of the dirt removing methods is a method in which pelletized resin-made abrasives are mixed in the collected pachinko balls and transferred while being stirred to scrape off the dirts with the abrasives.

The abrasive used in this method needs to have a surface hardness that does not damage the pachinko balls, and mainly polyamide (nylon) thermoplastic resins are used. Incidentally, the resin abrasive is used not only for pachinko balls but also for removing dirt from strobe machines and coins for various game machines.

Among these abrasive materials is Japanese Patent Laid-Open No. 3-1314.
As disclosed in Japanese Unexamined Patent Publication No. 70-70, a conductive component is added to a resin to prevent static electricity, or an antibacterial and deodorant is added as disclosed in Japanese Patent Application Laid-Open No. 4-268336 to improve antibacterial and deodorant properties. There are also things that have been elaborated such as giving.

[0005]

A game hall such as a pachinko parlor or a game center should have a comfortable environment for the player. Therefore, it was considered to add a fragrance to the abrasive and transfer the scent to a pachinko ball or a coin for a game machine during the polishing process so that an aroma is caused to float in the hall.

However, the method of simply adding a fragrance to the thermoplastic resin cannot provide an ideal abrasive that emits a fragrance for a long period of time. The reason is that the volume ratio of liquid perfume to the resin is limited to about 3% at maximum, and the scent is too thin, and the scent trapped inside is not released to the outside due to the dense structure of the resin. However, the effect of aroma emission is lost in a short time.

An object of the present invention is to solve this problem and to realize a perfume-containing resin abrasive material in which the fragrance is sufficiently diffused and the fragrance is maintained for a long time.

[0008]

In order to solve the above problems, in the present invention, a perfume is adsorbed on a powdery perfume adsorbent and is kneaded into a thermoplastic resin together with the adsorbent.
The mixing ratio is preferably 0.5 Vol% to 15 Vol% for the fragrance and 1 Vol% to 20 Vol% for the fragrance adsorbent.

The fragrances used include citrus fragrances such as cypress oil and cedar oil, terpene compounds, citrus fragrances such as lemon oil, orange oil and mandarin oil, and deodorants that eliminate unpleasant odor components by chemical reaction. And so on.

The flavor adsorbent is preferably calcium carbonate powder or silica powder.

[0011]

In the present invention, since the fragrance is adsorbed on the adsorbent and added to the resin, the upper limit of the possible fragrance addition rate, which was about 3% when the adsorbent was not added, can be greatly improved.

[0012] When the addition rate increases, the scent that is emitted naturally increases.

Further, since the adsorbent is porous, and the addition of this adsorbent makes the dense structure of the thermoplastic resin porous, the perfume inside also gradually exudes and is diffused to the outside, which is effective. It has a longer lasting effect and gives off aroma over a long period of time.

The amount of perfume that can be added depends on the amount of adsorbent added. If the amount of the adsorbent is 1 vol% or less, the resin structure becomes insufficiently porous. Also, 20Vo
If it is 1% or more, the durability and polishing characteristics of the abrasive may be deteriorated. Therefore, the amount is 1 Vol% to 20 Vo.
1%. By setting the upper limit of the adsorbent addition amount, the upper limit of the fragrance addition amount is about 15 Vol%. The lower limit of the amount of perfume added may be lower than when no adsorbent is added because the scent will be emitted from the inside by the addition of adsorbent, and the effect of the addition was seen from about 0.5 Vol%. It was 0.5 Vol%. However, if added in an amount of about 2 to 3% by volume, the scent is thin and there is a feeling that it is unsatisfactory. Therefore, it is more preferable to set the lower limit to about 5% by volume.

Next, it is preferable that the flavoring agent gives the player a feeling of comfort rather than an exciting one. Japanese cypress oil listed above,
Cedar oil and terpene compounds have so-called forest bathing effects, and antibacterial effects can be expected. In addition, citrus fragrances are widely popular with humans, which also has the effect of making a tasteless environment comfortable. The deodorant is also effective in such a case because discomfort increases when the game hall is filled with cigarette smoke and body odor.

The adsorbent is not particularly limited to powders of calcium carbonate and silica, but these two are particularly preferable because they have a high adsorption rate, are easily available, and are inexpensive.

[0017]

[Examples] 6 nylon resin as a base thermoplastic resin, 5% by weight of cypress oil to 6 nylon resin as a fragrance, and 8% by weight of 6 nylon resin as a fragrance adsorbent The respective amounts of calcium carbonate powder were prepared. Then, the calcium carbonate powder is impregnated with cypress oil, and then this is kneaded into 6 nylon resin, and thereafter,
The kneaded material was processed into pellets having a cylindrical diameter of 4 mm and a length of 4 mm and cured to obtain a perfume-containing abrasive.

This prototype abrasive (invention product) was actually used for polishing pachinko balls, and the persistence of aroma emission was evaluated. As a result, it was confirmed that the scent was sufficiently emitted even after 3 months from the start of use.

Further, during polishing of the pachinko balls, the temperature of the abrasive rises to about 40 ° C. to 45 ° C. due to frictional heat, and the heat accelerates the volatilization of the hinoki oil in the abrasive to emit a strong scent. I knew that. The above-mentioned aroma emission state after 3 months has been examined after polishing was performed at an average frequency (thus, volatilization and emission promoted by temperature rise are repeated many times). Since the results were satisfactory, there was a prospect of commercialization.

It was feared that the addition of the powder filler (here, calcium carbonate) would weaken the strength of the abrasive and promote its wear.
Actually, no remarkable decrease in wear resistance was observed, and the sharp edges of the pellets remained in a state close to the initial shape even after 3 months of use.

Next, a comparative product was prepared and evaluated. As a comparative product, 6% nylon resin was added with 3% by weight of cypress oil, and after kneading, the diameter was 4 mm,
It was obtained by processing into a pellet having a length of 4 mm. The cypress oil addition here could be easily done without taking any special method.

However, when the thus obtained comparative product was used for polishing pachinko balls, the scent of cypress oil was only felt immediately after use, and the scent was lost after a while.

Further, when this comparative product was opened after being sealed and stored, a scent was produced at the time of opening, but after that, the scent was no longer felt.

[0024]

As proved by the above experiment, since the abrasive of the present invention is added by adsorbing the fragrance on the adsorbent in the thermoplastic resin, it is excellent in stability and sustainability of fragrance emission. A scent that refreshes the player's mood can be transferred to pachinko balls and coins for gaming machines to maintain a comfortable environment inside the game hall at all times.

Since the pachinko balls and coins for gaming machines are used directly by the player, it is very preferable to add an aroma to them so that all players can feel refreshed. Is.
