1. Field of the Invention
The present invention is related to a method for making a three-dimensional laser tag with in-mould injection and particularly to a method for forming laser figures or marks on a transparent membrane and performing stamping in advance so as to allow the laser figures or marks providing corresponding three-dimensional shapes.
2. Brief Description of Related Art
The conventional laser tag as shown in
However, the figure or mark 1 is disposed on the surface of the aluminum foil 100 such that the base color shown by the laser tag is the color of the aluminum foil itself, i.e., the silver gray color and the base color is unchangeable. Therefore, it is hard to achieve technically for the base color being provided with different colors and even providing arrangement of seven typical colors. Further, the preceding laser tag is attached to the flat or slightly bent surface of the aluminum foil so that the laser tag do not provide a sense of three-dimension. In case of the laser tag being adhered to a surface of the article with a large curvature, the laser tag becomes wrinkled due to the aluminum itself being as thin as a paper sheet while the laser tag is adhered to the surface of an article. Under this circumference, it is easy to come off even if the laser tag is adhered with an external force on purpose so that the application of the laser tag is restrictedly limited to a certain extent. In addition, it is difficult to add a counterfeit proof device to the conventional laser tag because it is very easy for the conventional laser tag being copied or torn off due the laser tag being glued to the surface of an article.
Besides, another traditional technique provides a transparent membrane printed with a figure and the transparent membrane at the area of the figure is performed with empty print and a laser tag treated with full image technique is adhered to the empty area of the transparent membrane before a plastic layer is made with injection molding. Although the prior art can avoid being torn off, deficiencies such as showing a single color of aluminum foil only, requiring flat surface adhesion arrangement and providing no sense of three dimension. Moreover, the manufacturing process to make the laser tag is complicated so that the production cost is comparatively higher.
An object of the present invention is to provide a method for making a laser three dimensional tag with in-mould injection, which allows the tag being formed three dimensionally, provided with different colors, not easy to become released and low in production cost.
In order to achieve the object, a method for making a laser three dimensional tag with in-mould injection according to the present invention includes the following steps:
(A) at least a laser figure or mark being roll-printed on a transparent membrane with a full image technique;
(B) the transparent membrane 20 with the laser figure or mark being printed with an ink layer;
(C) a medium layer being printed on the ink layer, which has been printed on the transparent membrane;
(D) the membrane with the laser figure or mark being treated three-dimensional stamping to form a three dimensional shape;
(E) the three dimensional membrane in association with the laser figure or mark 10 is treated with trimming; and
(F) the component being completed with injection molding with the laser figure or mark between the transparent membrane and the ink layer.
When the laser figure or mark is formed on the transparent membrane, the transparent membrane keeps transparent in spite of the laser figure or mark having been roll-printed thereon.
The laser figure or mark can be roll-printed at the front side or backside of the transparent membrane.
The laser figure or mark can be an artwork, a trademark logo or a figure with encryption code.
The plastic layer formed by way of injection molding is joined to the medium and the transparent membrane.
A base color shown with the laser figure or mark is the same as the ink color.
Due to the transparent membrane being stamped, the laser figure or mark provides a shape corresponding to the shape of the transparent membrane.
The laser figure or mark is formed on the transparent membrane and stamped in advance so as to make the laser figure or mark providing a long lastingly three-dimensional shape corresponding to the transparent membrane, showing enriched colors of the printing ink layer and the manufacturing process is relatively simple so as to lower production cost significantly.
The detail structure, the applied principle, the function and the effectiveness of the present invention can be more fully understood with reference to the following description and accompanying drawings, in which:
Referring to
(A) At least a laser figure or mark 10 is roll-printed on a transparent membrane 20 with a full image technique and the laser figure or mark 10 can be a figure of art, a trademark standing for a company or an encrypted pattern. The decorated figure or mark 10 can be roll-printed at the front side or back side of the transparent membrane 20 for being chosen while in use.
(B) The transparent membrane 20 with the laser figure or mark 10 is printed with an ink layer 30. The ink 30 provides effect of color decoration and is printed to the side, which has the decorated figure or mark 10. The ink print technique can utilize screen mask printing or the like.
(C) A medium layer 40 is printed on the ink layer 30, which has been printed on the transparent membrane 20. That is, the facial side of the ink layer 30 contacts with the medium layer 40 and backside thereof contacts with transparent membrane 20. The medium layer 40 assures the ink layer 30 being firmly adhered to and coated between the transparent membrane 20 and a plastic injected layer 50, which is formed in the subsequent step of the manufacturing process. In this way, the colorful ink layer 30 keeps fresh and is good looking without being flaked off after using a long period of time.
(D) The membrane with the laser figure or mark is treated three-dimensional stamping to constitute a three dimensional shape. A mold tool is used to stamp the membrane 20 with Laser decorated figure or mark 10, the ink layer 30 and the medium layer 40 in advance so as to form a three dimensional configuration. In this way, Laser decorated figure or mark represents an effect of being distributed as three-dimensional shape.
(E) The three dimensional membrane in association with the laser figure or mark 10 is treated with trimming. The peripheral of the formed three-dimensional membrane 20 with Laser figure or mark 10 is trimmed for the subsequent injection molding operation.
(F) The component being completed with injection molding with the laser figure or mark between the transparent membrane and the ink layer. A plastic layer 50 is form from the transparent membrane 20 with Laser figure or mark 10, the ink layer 30 and the medium layer 40 by way of injection molding to complete the required component. The plastic layer 50 is joined to the transparent membrane 20 and the Laser figure or mark 10 is disposed between the transparent membrane 20 and the ink layer 30.

Referring to
Further, the Laser figures or marks 10′, 10″ and 10′″ are integrally formed on the transparent membrane 20 instead of adhering to the transparent membrane 20 so that problem of the Laser figures or marks 10′, 10″ and 10′″ releasing from the transparent membrane 20 can be avoided. In order to prevent from being counterfeited, an encrypted code can be added. Hence, the manufacturing process disclosed in the invention is much simpler than the conventional art and the production cost can be lowered tremendously.
It is appreciated that a method for making three-dimensional Laser tag with in-mold injection according to the present invention provides a transparent membrane integrally with Laser figures or marks being stamped as three-dimensional shapes and the Laser figures and marks keep staying on the transparent membrane without falling off easily. Comparing to the conventional Laser tag, the Laser figures or marks made with the method of the present invention offer a variety of color selections except aluminum base color and can be arranged as three-dimensional shapes instead of a flat shape. Further, the method of the present invention has simple manufacturing process and the production cost can be lowered significantly.
While the invention has been described with referencing to preferred embodiments thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
