Description

Retention Label Designed To Prevent Ink Leakage

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to retention labels that prevent ink leaching, and more particularly, to retention labels on which labels are adhered to a bottle made of glass.

Generally, drinking water, such as beer, milk, juice, bottled water or lemonade, is manufactured and marketed in bottles made of glass. The bottle made of the glass material is commercially available and then recovered. The recovered bottle is washed and then refilled with commercially available drinking water. Here, the bottle has a label printed on the front surface of the bottle indicating the drinking water.

Thus, when the bottle is collected and cleaned, the label is removed and the label is adhered to the bottle when it is commercially available again.

Examples of removing a label adhered to a bottle made of a PET material among the bottles are Korean Patent Application No. 98-9867, Korean Patent Application No. 98-31463 and Korean Patent Application No. 98-31482 It is disclosed in the call.

According to Korean Patent Application Nos. 98-9867 and 98-31482, the label is removed using an apparatus, and Korean Patent Application No. 98-31463 is removed using a solvent.

Among the bottles, the bottles made of glass material are somewhat unreasonable in terms of material properties to be removed using the apparatus. That is, there is a risk of damage when removed using the device. Therefore, the label adhered to the bottle is mainly removed using a solvent, and the label is removed using an aqueous solution containing sodium hydroxide as the solvent. At this time, the aqueous solution contains about 4% by weight of sodium hydroxide.

Therefore, the label adhered to the bottle made of glass material contains the aqueous solution containing sodium hydroxide in the bottle member, and the bottle is heated for about 10 to 15 seconds while the aqueous solution is heated to a temperature of 80 ° C to 85 ° C. Dipping removes the label after 10 to 20 minutes after the ink has been separated and released from the label.

At this time, the label is removed and contaminates the aqueous solution in the process of dissolving the ink printed on the label, thereby causing a situation in which the dissolved ink floating material enters into the bottle where cleaning is performed. The constituents of the aqueous solution are changed due to the ink suspended solids. When the continuous cleaning is performed, the aqueous solution needs to be replaced.

Therefore, a label adhered to a bottle made of a conventional glass material has a problem in that when the label is removed, ink dissolves to generate a floating material, thereby degrading cleaning efficiency due to the floating material. In addition, since the suspended solids remain in the aqueous solution for cleaning, there is a problem that the aqueous solution must be replaced frequently.

An object of the present invention is to remove a label adhered to a bottle made of glass material with an aqueous solution of sodium hydroxide, and a label printed retention label that can minimize the occurrence of suspended solids due to leaching of ink printed on the label. To provide.

The label printed with the trademark of the present invention for achieving the above object is made of a pulp, the adhesive portion which is bonded to the glass material in contact with, and formed on the adhesive portion, the agent for mediating the adhesion of the metal material to the adhesive portion And a metal portion formed on the media portion, formed of a metallic material, and visually contrasted with an ink representing a trademark, and formed on the metal portion to prevent oxidation of the metal portion, A second mediating section for mediating adhesion, a printing section printed using the ink on the second mediation section, a coating section formed on the printing section, and having ink resistance and friction resistance, constituting the printing section; The surface of the coating portion is formed in an embossed shape, and includes an embossing portion that protects members formed below the coating portion and reacts with sodium hydroxide (NaOH) solution.

The first portion is composed of 10 to 15% by weight of an acrylic copolymer (acryl copolymer) and the remaining amount (solvent), the second portion is 25 to 35% by weight of a polystyrene copolymer (PS) and It is composed of 2 to 5% by weight of acrylic resin and the remaining amount of solvent. And the ink constituting the printing portion is 8 to 15% by weight of polyamide, 5 to 9% by weight of nitro cellulose, 1% by weight or less of an antistatic agent, 1 to 2% by weight It consists of polyethylene wax, 1 to 5% by weight of a hardener (hardener, curing agent), 5 to 10% by weight of organic pigment (organic pigment) and the balance of the solvent. In addition, the embossed portion reacts with an aqueous solution containing 1.5 to 2.5% by weight of sodium hydroxide (NaOH).

Removal of the label having the above constitution uses an aqueous solution containing 1.5 to 4% by weight of sodium hydroxide. In addition, since the ink constituting the printing unit is continuously adhered by the coating unit when the label is removed, the situation in which the ink melts can be minimized. Therefore, it is possible to minimize the generation of suspended substances due to the ink. That is, by removing the label, the ink constituting the printing unit is continuously adhered, thereby minimizing the effect caused by the ink.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view showing a bottle made of a glass material adhered to a label printed with a trademark.

Referring to FIG. 1, a bottle made of a glass material is shown. On the front side of the bottle a label with a printed label is adhered. The label is printed with a label indicating the characteristics of the component contained in the bottle using ink.

Here, since the bottle is a subject that can be recycled, the bottle containing the drinking water is recovered after being sold in the market. The collected bottles are then washed in a state capable of recycling. In this cleaning process, the ink printed on the label should not be dissolved in the aqueous solution for cleaning.

Therefore, the label has a configuration in which a plurality of constituent members are laminated so that the ink does not dissolve.

2 is a cross-sectional view illustrating a label printed with a trademark according to an embodiment of the present invention.

Referring to FIG. 2, an adhesive part is formed in which a glass bottle is attached and bonded. The adhesive part is a paper material composed of pulp. A first intermediate portion is formed on the adhesive portion. The first intermediary mediates easy adhesion between the adhesive portion and a member to be subsequently formed on the first intermediary.

Wherein the first mediated portion consists of 10 to 15% by weight of an acrylic copolymer and a residual solvent.

A metal part made of aluminum is formed on the first intermediate part. The metal portion is formed to visually contrast the design of the trademark by making the trademark itself printed on the label opaque. A second mediated portion is formed on the metal portion. The second mediation portion prevents oxidation of the lower metal portion and mediates adhesion between the metal layer and ink of the printing portion to be printed later.

Wherein the second mediated portion is comprised of 25 to 35 weight percent polystyrene copolymer, 2 to 5 weight percent acrylic resin and residual solvent.

On the second intermediate portion, there is formed a printing portion composed of ink which prints a trademark. Accordingly, the trademark is expressed through the printing unit.

Wherein the ink with the trademark printed thereon is 8 to 15 wt% polyamide, 5 to 9 wt% nitro cellulose, up to 1 wt% antistatic agent, 1 to 2 wt% polyethylene wax, 1 to 5 wt% hardener , 5 to 10% by weight of organic pigments and the remaining amount of solvent.

A coating portion is formed on a printing portion on which a trademark is printed using the ink. The coating part has friction resistance with the ink of the printing part. Therefore, the gloss of the ink is improved by the friction resistance, thereby securing a visual field of view. An embossing portion having a surface embossed configuration is formed on the coating portion. The embossing part protects the members formed below the coating part. And forming the surface of the embossing portion in the form of embossing is to ensure that the aqueous solution containing the sodium hydroxide when the label is removed well. Wherein the aqueous solution comprises 1.5 to 2.5 wt% sodium hydroxide and penetrates through the embossed portion to remove the label from the bottle.

Looking at the removal of the label during the cleaning of the bottle to which the label having the above constitution is adhered, a bottle member for accommodating an aqueous solution containing approximately 2.0% by weight of sodium hydroxide is prepared. The aqueous solution is heated to about 80 ° C. to 85 ° C., and then the bottle to which the label is adhered is immersed in the bottle member. As a result, the aqueous solution penetrates into the embossing portion, which is the uppermost layer of the label, and then penetrates downward to lower the adhesion function of the bonding portion. Thus the label is removed from the bottle.

At this time, the ink constituting the printing portion of the label is not affected by the aqueous solution. This is because the coating portion constituting the label adheres the ink, and the following second intermediate portion also adheres the ink.

Among the constituent members included in the label of the present invention, the constituents constituting the inks of the first and second intermediate parts and the printing part are as follows.

As described above, it can be confirmed that the first and second mediators and the ink of the present invention have different components from those of the prior art.

Therefore, it can be easily removed in an aqueous solution containing 1.5 to 4% by weight of sodium hydroxide, and the situation in which the ink is dissolved and melted by the aqueous solution can be minimized. Accordingly, it is possible to minimize the generation of suspended solids by the ink when removing the label.

Therefore, according to the present invention, it is possible to minimize the occurrence of suspended solids due to dissolution and leaching of the ink printed on the label when removing the trademark label, and to prevent the suspended solids from entering into the aqueous sodium hydroxide solution and the bottle in advance. Effective cleaning can be expected.

In addition, since the floating material in the aqueous solution is not mixed with the aqueous solution, there is an advantage that the aqueous solution can be repeatedly recycled and used. Therefore, there is an effect that can reduce the use of the aqueous solution. For example, as a result of removing the label of the present invention as compared with the prior art, it was confirmed that the use time of the aqueous solution was extended by about three times. This is equivalent to reducing the consumption of the aqueous solution by about three times or more.

In addition, by actively limiting the use of sodium hydroxide can be actively cope with the treatment of sodium hydroxide, it can be expected to be able to actively cope with environmental pollution prevention.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the present invention without departing from the spirit and scope of the invention described in the claims below. I can understand that you can.
