Abstract

PURPOSE:To perform the titled decoration in a short time using a simple device by semi-hardening a projected adhesive layer on the surface of glass comprising an ultraviolet ray hardenable ink forming then a metal transfer layer thereon, further baking the adhesive layer from the rear side. CONSTITUTION:A projected adhesive layer 2 is formed on the surface of a transparent glass bottle 1 by printing characters or patterns of specified shapes using an ultraviolet ray hardenable ink having superior affinity and adhesion. The surface of the layer 2 is then irradiated with ultraviolet rays using an ultraviolet ray irradiator 3 weakly for ca. 1 sec to dry the layer 2 forcible so as to attain semihardened state. After evaporating a metal on the surface of the layer 2, a sheet of hot stamping foil 4 is placed thereon, the foil is pressed with a hot elastic body 5. The metal foil remains only on the surface of the layer 2 when the foil is removed; thus a transfer layer 6 is formed. Finally, the layer 6 is irradiated with ultraviolet rays for ca. 5 sec from the rear side of the layer 2 through the glass to bake the layer 2 to the surface of the bottle 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method of printing glitter metallic characters or designs on the surface of glass such as glass containers, etc., by using a simple device and in a short period of time. It relates to a method of decorating characters, designs, etc.

Conventionally, in order to print bright metallic characters or designs on the surface of glass containers, etc., characters or designs in a predetermined shape are printed using synthetic resin ink to form an adhesive layer, and then metal foil is added on top of that. A method of printing glittering metallic characters or designs by pressing is used.

However, with this method, it takes about 5 to 6 minutes to dry the contact layer to a semi-hardened state, and the baking time after pressurizing the metal foil also takes about 3 minutes at a temperature of around 150°C.
Currently, it takes about 0 minutes or more. Moreover, since a base drying oven and a baking oven are used for baking, the equipment and space thereof are required, resulting in a disadvantage that the cost of equipment and the like increases considerably.

Therefore, the present invention was created in view of these drawbacks, etc., and its gist is to print characters or designs in a predetermined shape on the surface of glass using ultraviolet curable ink with good affinity and adhesion. After printing the raised adhesive layer to form a raised adhesive layer, and forcing the raised adhesive layer to dry to a semi-hardened state using an ultraviolet irradiation machine, hot stamping foil with metal vapor deposition is placed on the surface of the raised adhesive layer and heat elasticity is applied. The method consists in forming a transfer layer by pressing with a body, and then irradiating ultraviolet rays from the back side of the raised adhesive layer with an ultraviolet irradiator for a predetermined period of time and baking.

Hereinafter, the present invention will be described in detail with reference to the drawings.

Reference numeral 1 shown in the figure is a transparent glass bottle used as a container for cosmetics, etc., and on the surface of the glass of this glass bottle 1,
Using ultraviolet curable ink (LIV ink) with good affinity and adhesion, that is, ink that cures when exposed to ultraviolet rays and becomes an adhesive, letters or designs of a predetermined shape are printed and raised to form an adhesive layer. form 2.

Then, as shown in FIG. 1, the surface of this adhesive layer 2 is irradiated with ultraviolet rays for about 1 second using an ultraviolet irradiator 3, and forced drying is performed so that the adhesive layer 2 is in a semi-cured state. As shown in the figure, a hot stamping foil 4 on which a metal such as aluminum is vapor-deposited is superimposed on the surface of the adhesive layer 2, and a heated elastic body 5 is used to press the hot stamping foil 4 onto the surface of the adhesive layer 2, and then the hot stamping foil 4 is removed. The metal foil remains only on the surface, and the transfer layer 6 is formed.

Next, as shown in FIGS. 3 and 4, ultraviolet rays are irradiated from the back side of the adhesive layer 2 through the glass for about 5 seconds to bake the adhesive layer 2 onto the glass surface, thereby attaching glittering metallic letters or designs to the glass. It is used to decorate the surface.

Therefore, it is possible to decorate the surface of glass such as a glass container with glittering metallic characters or designs in a very short time and with a simple device.

That is, by printing letters or designs of a predetermined shape on the surface of the glass using ultraviolet curable ink with good affinity and density, and forming a raised adhesive H2, metal foil can be applied to the surface of the adhesive layer 2. When dried by repeated UV irradiation, the metal foil remains bonded to the contact layer 2, and since UV-curable ink is cured and dried by UV rays in a short time, it is possible to quickly apply the metal foil to the glass surface. , and can be bonded using a simple device such as an ultraviolet irradiation machine.

After the adhesive layer 2 is forcibly dried to a semi-hardened state using an ultraviolet irradiator 3, a hot stamping foil 4 coated with metal vapor deposition is layered on the surface of the raised adhesive layer and is pressed by a heated elastic body 5. By forming the transfer layer 6, the hot stamping foil 4 can be transferred easily and with strong adhesive force because ultraviolet rays are applied to the adhesive layer 2 to a semi-cured state where the adhesive effect is maximized.

Further, by irradiating and baking the raised adhesive layer 2 with ultraviolet rays for a predetermined time from the back surface of the adhesive layer 2 using the ultraviolet irradiator 3, the hot stamping foil 4 is overlaid and pressure-bonded after the aforementioned ultraviolet rays are irradiated to a semi-cured state. The hot stamping foil 4 can be protected from deterioration due to ultraviolet rays and heat rays, and can be baked with strong adhesive force in a short time, so it can be used to print excellent metallic characters or figures 'Fi' on glass with high brightness. The surface can be decorated.

As explained above, the present invention significantly shortens the drying and baking time compared to the case where an adhesive layer is formed using conventional synthetic resin-based ink. There is no need for a baking oven and only an ultraviolet irradiation machine is needed, so equipment costs can be kept low, and since the work is simple, fewer workers are needed, resulting in a significant reduction in decoration costs. It becomes possible to aim for
Furthermore, since the hot stamping foil is not directly irradiated with ultraviolet rays, excellent effects such as the ability to decorate the glass surface with metallic characters or designs with high brightness can be achieved.

Detailed Description of the Invention This invention (1) The surface of glass such as crow containers (2) A crow with the ability to print bright metallic letters or designs with a simple device and in a short time. This relates to a method of decorating the surface with glittering metallic letters or designs. Conventionally, in order to print glittering metallic letters or designs on the surface of a glass container, etc., synthetic resin-based ink was used. A method has been used in which characters or designs of a predetermined shape are printed using adhesive, and then metal foil is pressed on top of it (printing glittering metallic characters or designs 1). However, this method Then, it takes about 5 to 6 minutes to dry the adhesive layer to a semi-hardened state, and it also takes about 10 minutes to bake the metal foil after pressurizing it at a temperature of around 0°C. Currently, it takes about 30 minutes.Furthermore, since a base drying oven and a baking oven are used for baking, equipment and space are required, and the equipment costs are extremely high. Therefore, in view of these drawbacks, the present invention was developed. A raised adhesive layer is formed by printing a predetermined shape of letters or designs with ink, and this raised adhesive layer is force-dried to a semi-hardened state using an ultraviolet irradiation machine.After 1c, metal is applied to the surface of the raised adhesive layer. Layer the vapor-deposited hot stamping foils and use the heated elastic body to
The process consists in forming a transfer layer using a t@u method, and then irradiating ultraviolet rays from the back side of the raised adhesive layer for a predetermined period of time using an ultraviolet irradiation machine to bake it. Hereinafter, the present invention will be described in detail with reference to the drawings. Reference numeral 1 in the figure is a transparent glass bottle used as a container for cosmetics, etc. On the surface of the glass of this glass bottle 1,
Rinawa 1 is an ultraviolet curable ink (UV ink) with excellent affinity and adhesion that cures once exposed to ultraviolet rays and becomes an adhesive to form letters or designs in a predetermined shape. The raised adhesive layer 2 is formed by printing. . Then, as shown in FIG. 1, the surface of the adhesive layer 2 is exposed to ultraviolet rays for about 1 second using an ultraviolet irradiator 3, and forced drying is performed so that the adhesive layer 2 becomes semi-cured. then the second
As shown in the figure, a hot stamping foil 4 on which a metal such as aluminum is vapor-deposited is superimposed on the surface of the adhesive layer 2, and a heating elastic body 5 is used to press the hot stamping foil 4 on top of the adhesive layer 2, and then the hot stamping foil 4 is removed ( The metal foil remains only on the surface of the adhesive layer 2 to form the transfer layer 6. Next, as shown in FIGS. 3 and 4, ultraviolet rays are irradiated from the back side of the adhesive layer 2 through the glass for about 5 seconds. This method is used to decorate the surface of the glass with glittering metallic letters or designs by "burning layer 1 and layer 2 of the JL glass in a very short time." With a simple device, it is possible to decorate the surface of glass such as glass containers with glittering metallic letters or designs.In other words, letters in a predetermined shape can be printed on the glass surface using ultraviolet curing ink that has good affinity and adhesion. Alternatively, a raised adhesive layer 2 is formed by printing a design, etc., and then hot stamping is performed as a metal 35 on the surface of the adhesive layer 2 semi-cured by ultraviolet rays h) When 4 is overlaid, only the portion of the layer 2 that contacts is hot stamped. Shima 4 remains glued, and since UV-curable ink hardens and dries in a short time due to UV rays, the metal foil can be bonded to the glass surface in a short time and with only a simple device such as an UV irradiator. After the adhesive layer 2 is forcibly dried to a semi-cured state using an ultraviolet irradiator 3, metal foils 1 to 4 stamped with metal vaporization are layered on the surface of the raised adhesive layer and heated. By forming the transfer layer 6 by pressing with the elastic body 5, the hot stamping foil 4 is irradiated with ultraviolet rays to a semi-cured state where the adhesive effect of the adhesive layer 2 is maximized, so that the hot stamping foil 4 has a strong adhesive force on the adhesive layer 2. Further, the back surface of the raised adhesive layer 2 is irradiated with ultraviolet rays for a predetermined period of time by an ultraviolet irradiator 3 and baked (baked). Combined with the overlapping pressure Wl, the hot stamping foil 4 can be protected from deterioration due to ultraviolet rays, heat rays, etc., and moreover, it can be baked with strong adhesive force in λ0 hours, so it has high brightness. It is great to be able to decorate the glass surface with excellent metallic letters or designs.As explained above, this invention is superior in comparison to the case where an adhesive layer is formed using a conventional synthetic resin ink. As a result, the drying and baking time is greatly shortened, and the installation cost can be kept low by using only an ultraviolet irradiation machine without the need for a conventional base drying oven and baking oven. In addition, since the work is easy, the number of workers is reduced (this makes it possible to significantly reduce decoration costs, and furthermore, the hot stamping foil is not directly irradiated with ultraviolet rays). This provides excellent effects such as the ability to decorate the surface of the crow with metallic characters or designs that are rich in glitter. 4.
