Description

In-mold curved label structure

technical field

The invention relates to an in-mold forming curve label structure, especially a label that can be integrated with a corresponding plastic product of any shape. In the process of plastic injection molding, vacuum molding, hollow molding, or extrusion molding, The label can be integrally formed and fully combined with the product.

Background technique

Most of the commercially available plastic products are printed with decorative patterns or characters on the surface of the plastic products after they are processed and shaped. Not only is the aesthetic feeling not good, but the colors and patterns are not lively and cannot attract consumers' attention.

Therefore, commercially available plastic products are made by integrally molding plastic labels and plastic products, but this kind of plastic label needs to be printed with a pattern in advance, and then glue the inner layer of the plastic label, and then glue the outer layer with a glued layer, and the plastic The printing of the label adopts the letterpress printing method, and the printing cost is high, so that the price of the plastic product is too high, which is not economical.

In addition, self-adhesive labels are pasted on the surface of plastic products to achieve the purpose of product labeling and decoration. There are many commercially available products, but this method cannot produce an integrated product because the label will have obvious bonding marks with the plastic product. Visual experience, for plastic products, does not match the economic value and aesthetic feeling.

Furthermore, currently commercially available plastic products are integrally molded labels, as shown in Figure 1, wherein the label 1 is printed with decorative figures or characters, and its side walls 10, 11 are formed according to the shape of the label, and keep a straight line. , the above-mentioned known label is more suitable for the container as shown in Figure 2. The outer diameter of the surrounding wall 20 of this kind of container 2 forms a shape that gradually decreases from top to bottom. Therefore, the label can be fully combined with the surrounding wall 20 of the container 2. , there will be no wrinkle problem.

But when the shape of the container 3 as shown in Fig. 3, the surrounding wall surface 30 of the container 3 is provided with the surrounding wall surfaces 300, 301 of different outer diameters, and the junction 302 of the two surrounding wall surfaces 300, 301 will form a high protruding shape In this way, when the aforementioned label and the container are in-molded, the label 1 will form wrinkles 303 due to the joint 302 of the container 3, because the joints of the two side walls 10, 11 of the label 1 are joined by the high protrusion of the container Squeeze at the place, but there will be mold pressure and air nowhere to vent. Therefore, none of the labels currently available on the market can be applied to containers with two or more different outer diameters of the surrounding wall surfaces 300, 301, because a large number of defective products will be produced, causing great troubles.

For this reason, the inventor has accumulated many years of experience in designing and developing various new products, and has made in-depth research on the shortcomings of the previously disclosed labels, and proposes the present invention.

Contents of the invention

The technical problem to be solved by the present invention is to provide an in-mold curve label structure that matches the shape of the plastic product to integrally form the label and the plastic product and improve the shape change and value of the integrally formed plastic product of the in-mold label.

The technical solution of the present invention is: an in-mold forming curve label structure, which includes: a label, the label is provided with two side walls, and the side wall is provided with a curved portion, the curved portion and the side wall form a section, the The interval or curve part is set according to the surface shape of the plastic product.

The present invention also proposes another in-mold forming curve label structure, which includes: a label, the label is provided with two side walls, the side walls are provided with a curved portion, and the curved portion and the side wall form a section, and the section or the curved section is set It is made according to the surface shape of the plastic product; and the label is also provided with a small cut part matching the surrounding part of the plastic product.

Features of the present invention have:

1. In the molded curved label structure of the present invention, a curved portion is provided on the label, and the curved portion is formed to match the surface shape of the plastic product.

2. In the molded curved label structure of the present invention, the label is provided with small cutouts matching the surrounding parts of different outer diameters of the plastic container, so that the aforementioned label can be combined with the corresponding plastic product of any shape to form an integral body.

Utilize the above-mentioned curved portion and/or small cut portion to release the pressure and gas in the mold during the molding process of the plastic product, and use the stretch of the label material to make a plastic product with a perfect appearance, which improves the integral molding of the in-mold label. Product shape change and value.

Detailed ways

In this way, in order to fully understand the present invention, it is explained as follows according to the accompanying drawings:

Figure 4 to Figure 7 show the first embodiment of the present invention, as shown in the figure, the label of the first embodiment can be made of various available materials such as plastic material, aluminum foil material, paper material or metal material. Label 4 is printed with pattern or text 40, and establishes two sidewalls 41,42, and sidewall 41,42 establishes curved portion 43, and this curved portion 43 and sidewall 41,42 form section 44 (referring to Fig. 5), and this section 44, or the setting of the curved portion 43 is made in order to match the surface arc-shaped portion 50 of the plastic product 5, so the curved portion 43 can be provided with one or more than one in order to match the shape of the plastic product. Its purpose is to use this section 44 when the plastic product and the label are integrally formed to make the label side walls 41, 42 combined to produce an appropriate air-permeable effect instantly (see Figure 6 and Figure 7), ensuring that the plastic product is perfectly made every time of molding.

Also shown in Figure 8 to Figure 12 is the second embodiment of the present invention, as shown in the figure, the label of the second embodiment, as shown in the foregoing embodiment one, is made of various available plastic materials or aluminum foil materials or paper materials. made of materials. Label 4 is printed with pattern or text 40, and establishes two sidewalls 41,42, and sidewall 41,42 establishes curved portion 43, and this curved portion 43 and sidewall 41,42 form section 44 (referring to Fig. 9), and this section 44, or the setting of the curved portion 43 is made in order to match the surface arc-shaped portion 50 of the plastic product 5, so the curved portion 43 can be provided with one or more than one in order to match the shape of the plastic product. Furthermore, the label of the second embodiment is also provided with small cutouts 45 matching the surrounding parts 51 and 52 of different outer diameters of the plastic products 5, and one or more small cutouts 45 can be provided to match the shape of the plastic products. Its purpose is to utilize this section 44 when the plastic product and the label are integrally formed so that the side walls 41 and 42 of the label are combined instantly to produce a proper air-permeable and pressure-relieving effect, ensuring perfect plastic product molding every time.

And the curved portion 43 and/or the small cut portion 45 of the foregoing various embodiments can actually be a rhombus, or a triangle, or a circle, or an ellipse, or any geometric shape, or an irregular shape, as long as it can be matched The shape of the plastic product; or after the two side walls 41, 42 are combined, use the aforementioned curved portion 43 and/or small cut portion 45 to release the pressure and gas in the mold during the molding process of the plastic product, and use the stretching properties of the label material , to make plastic products with perfect appearance 5.
