JPS59145259A - Scratch coating composition for bottle - Google Patents

Abstract

PURPOSE:To provide a coating compsn. which is excellent in hiding effect and water resistance and can be completely peeled off during the washing of a bottle, by blending liquid paraffin, sorbitan fatty acid ester, higher alcohol fatty acid ester and glycerol fatty acid ester. CONSTITUTION:Liquid paraffin, sorbitan fatty acid ester, higher alcohol fatty acid ester and glycerol fatty acid ester are blended together. If necessary, an appropriate quantity of water is further added thereto. Any of the above three fatty acid esters has an emulsifying action. Liquid paraffin is effective in spreading over the surface of a bottle and increasing an action of penetrating into scratched regions. These fatty acid esters are used in such a proportion that they account for 25-5% of the total quantity of the compsn. The glycerol fatty acid esters include those derived form 10-21 C fatty acids, among which lauric acid, palmitic acid, stearic acid and oleic acid are preferred.

Description

[Detailed description of the invention] The present invention relates to compositions for coating damaged bottles.

Glass bottles used as containers for beer, fruit juice, etc. are collected and used repeatedly.

However, when these bottles are collected and used repeatedly, the outer surface of the bottles deteriorates during bottling and distribution processes.
%, abrasions occur on the shoulders, impairing the appearance and reducing the product value.

Therefore, when reusing collected bottles, it is necessary to inspect the bottles for the presence of scratches, and to cover any bottles with scratches by appropriate means.

Conventionally, various methods are used to cover scratches on bottles.
Compositions for application of seeds have been proposed. However, although conventional products have a good effect in hiding scratches, they have disadvantages such as poor drying properties due to their hygroscopic properties, sticky spots, and easy to attract dust, and the applied composition does not wash easily. There were problems such as not completely peeling off even after going through the bottle process. Since Sarak is expensive, it lacks practicality, and there are also some that are undesirable from a sanitary and safety standpoint.

An object of the present invention is to provide a composition for coating damaged bottles in which the above-mentioned problems are solved.

The present invention is a composition for coating damaged bottles, which contains liquid paraffin, sorbitan fatty acid ester, higher alcohol fatty acid ester, and glycerin fatty acid ester.

In the composition of the present invention, the liquid paraffin is a base that hides scratches on bottles, and is also allowed as a food additive. This liquid paraffin is used in an amount of 75 to 95%, preferably 80 to 90% in the composition.

Next, all three types of fatty acid esters have an emulsifying effect, and have the effect of increasing the ability of the liquid paraffin to diffuse onto the surface of the bottle and penetrate into scratched areas. These fatty acid esters account for a total of 25-5% of the composition.
, preferably 20 to 10%. In addition,
There is no particular restriction on the blending amount of each fatty acid ester, and it may be used so that the total amount becomes the above numerical value.

Here, the fatty acids of sorbitan fatty acid ester are lauric acid, valmitic acid, and stearic acid.

oleic acid, linoleic acid, lylunic acid, etc. (span) and polyoxyethylene sorbitan fatty acid ester obtained by reacting this span with ethylene oxide (
There is a tween). Higher alcohol fatty acid esters include those with an alcohol content of 06 to 0, such as decyl alcohol, lauryl alcohol, myristyl alcohol, etc., and fatty acids of C1 to 07. such as lauric acid, palmitic acid, stearic acid, and oleic acid.

Linoleic acid and the like are used. Also, as a glycerin fatty acid ester, fatty acids are negative.

~C2, are used, usually lauric acid,
Halmitic acid, stearic acid, oleic acid.

Linoleic acid, lilucic acid, etc. are preferred.

The composition for coating damaged bottles of the present invention can be obtained by blending predetermined amounts of each of the above-mentioned components, but an appropriate amount of water can also be added if necessary.

Various methods can be applied to coat bottles with the coating composition for scratched bottles of the present invention, such as a method using a spray device, a method using cloth, felt, a sponge, etc. .

As mentioned above, the base in the composition of the present invention is liquid paraffin, and if this liquid paraffin is used alone, the workability is poor and it is difficult to apply a small amount uniformly due to stains, but fatty acid esters as emulsifiers and By using them in combination, this problem was solved. Furthermore, the water resistance and texture after coating are also good. Furthermore, when bottles coated with the composition of the present invention are collected and reused, there is a risk that the composition may completely peel off during the bottle washing process. Moreover,
Each component used in the composition of the present invention is safe and can be stably obtained.

Next, the present invention will be explained in detail with reference to examples.

Example 1 Liquid halafine (trade name: Niramol Oil, manufactured by Kenritsu Kagaku) 76%, sorbitan fatty acid ester (trade name: Tw)
een 80, manufactured by Kako Atlas) 12%, higher alcohol/I/fatty acid ester (trade name: Nilauryl Stearate, manufactured by Tokyo Kasei) 8%, and glycerin fatty acid ester (trade name: Monolite, manufactured by Mi3. Shiyu) 4% using a homomixer SL type (manufactured by Tokushu Kika Kogyo) to 700 Ql.
ll for 5 minutes to uniformly disperse the mixture, to obtain 2 tons of a composition for coating damaged bottles.

This composition was soaked in absorbent cotton and applied to unevenly rubbed areas of beer bottles. After application, dryness due to tentacles.

We evaluated the effect of hiding scratches by visual observation, water resistance evaluation by immersion in water, appearance, feel, etc., and comprehensively judged whether the product was good or bad. As a result, this composition was evaluated as being good.

Example 2 The blending ratio of each ingredient is 84%.

Sorbitan fatty acid ester 7%, higher alcohol fatty acid ester ÷ 7% and glycerin fatty acid ester 2
The same procedure as in Example 1 was carried out except that % was used. The overall evaluation of this composition was good.

Example The blending ratio of each component is 96% liquid paraffin.

The same procedure as in Example 1 was carried out except that 4% of solhitan fatty acid ester, 2% of higher alcohol fatty acid ester and 1% of glycerin fatty acid ester were used. As a result, the overall evaluation of the obtained composition was good.

Claims (2)

[Claims] (1) A composition for coating scratched bottles comprising liquid paraffin, sorbitan fatty acid ester, higher alcohol fatty acid ester and glycerin fatty acid ester. (2) The composition according to claim 1, wherein the amount of liquid paraffin is 75 to 95%.
