Description

Roll label in-mold forming thermal insulation container

technical field

The invention relates to an in-mold thermal insulation container with a label, in particular to a thermal insulation foam container whose thermal insulation layer and label layer are integrally formed at the same time.

Background technique

Utilize the container made of foaming material at present, as the paper container disclosed in the new patent TWO95208544, as the first known product form, a bottom plate is arranged on the container body, and a coaming plate extending upward from the periphery of the bottom plate; the paper container It is also equipped with an inner waterproof layer, which is formed of polyethylene and polypropylene, and covered on the top surface of the bottom plate and the inner peripheral surface of the hoarding; the container also has a foam layer, which is made of polyethylene, polypropylene It is made of polylactic acid and can be coated on the outer peripheral surface of the enclosure of the container body in a heat-insulating manner.

The first product form can be as shown in Figure 4. An inner waterproof layer is set on the inner side of the container body. This inner waterproof layer is the waterproof layer processed on the inner layer of the common paper cup at present, that is, the distance between the container body and the inner waterproof layer. The combination is actually equal to a common paper cup, and then a heat-insulating foam layer is formed on the periphery of the container body of the paper cup, and the predetermined three-dimensional concave-convex pattern is formed around the foam layer in this kind of container, which is to use the foam layer on the periphery of the foam layer. The concave-convex state produced during foaming does not use any printing technology or method to print any pattern on the foam layer, so the preparation of the container is actually to process a heat-insulating foam layer on the periphery of the conventional paper cup.

Another example is the heat-insulating cup set disclosed in the new patent TWO95201048, which can be used as the second known product form. It is provided with a bottom cup, and a high-expansion foam insulation sleeve with a foaming ratio of more than 5 times is combined outside the bottom cup, so as to An insulating sleeve is formed on the periphery of the heat insulating cup. The product disclosed in this patent is at most equipped with a labeling film sleeve outside the insulating sleeve. According to the sixth item of the patent application scope of the published patent and the disclosure in the fourth figure, the marking film sleeve is formed after the insulating sleeve and the bottom cup are formed. Attached to (similar to pasting with a sticker) the outer surface of the insulating sleeve, that is, the combination of the marking film sleeve and the insulating sleeve is the most traditional method. It is necessary to use a laminating machine or manually to bond the marking film cover and the insulating cover into one, so as to achieve the purpose of combining the two.

Another example is the container structure with a heat-insulating surface layer disclosed in the new patent TWO95202037, which can be used as a third known product form, which is to form a foam layer on the outer layer of a paper or plastic container or a semi-finished product, so that the surface layer of the container is formed with reinforcement. , heat insulation, heat preservation, anti-scald foam layer. The three-dimensional pattern or pattern formed on the surface of the container is like the first product, which is pressurized on the foam layer to make the foam layer produce any concave-convex state, and is not printed on the foam layer by any printing technology or method. Print any pattern.

It can be said that the above-mentioned first to three known products are not heat-insulated containers manufactured by the container manufacturing method of in-mold label forming. They only solve the problem of heat preservation or heat insulation of paper cups or plastic cups, but do not solve other problems. The problem of exterior decoration.

Detailed ways

Below in conjunction with accompanying drawing, the scheme of the present invention is described in detail as follows:

As shown in Fig. 1 and Fig. 2, it is embodiment 1 of the thermal insulation container formed in the mold of the label of the present invention, and the thermal insulation container comprises:

The thermal insulation layer 1 is made of expanded polystyrene (EPS), expanded polyethylene (EPE), expanded polypropylene (EPP) or other foaming materials, and has been subjected to the first step before the thermal insulation layer is formed. The first foaming becomes granular, so when the thermal insulation layer 1 is molded in the molding mold, it is actually the second foaming molding;

The label layer 3, the label layer 3 can be pre-printed with various pictures, characters, colors, or documents with various intentions, etc., to form a representation of the appearance of the container. The label layer is pre-placed in the molding In the mother mold 2, after the container is formed, it can be integrated with the exterior of the thermal insulation layer 1 to form a decorative label on the exterior of the container;

The inner liner layer 4 is located inside the aforementioned thermal insulation layer 1. The inner liner layer 4 is preformed by plastic material, and is pre-placed in the container forming male mold 5 before the container is combined. After the container is formed, it can be Combined with the thermal insulation layer 1 to form the inner liner layer 4 of the aforementioned thermal insulation layer 1 . Of course, if it is made of paper or other materials, it can also be used to replace the above-mentioned inner liner layer made of plastic material first, if it has a high-temperature molding process that can withstand the thermal insulation layer.

In this way, to manufacture the in-mold thermal insulation container with label of the present invention, the label layer 3 and the inner liner layer 4 can be respectively pre-placed on the forming female mold 2 and the forming male mold 5 of the thermal insulation layer 1 (as shown in FIG. 1), when the thermal insulation layer 1 is formed, it can be combined with the label layer 3 and the liner layer 4 at the same time, so that the aforementioned thermal insulation layer 1, label layer 3 and liner layer 4 are integrally formed at the same time (As shown in Figure 2), the outer surface of the container can be provided with a label layer 3 with an excellent decorative effect, and an inner liner layer 4 is set on the inside of the container to improve expanded polystyrene (EPS), expanded polyethylene ( EPE), expanded polypropylene (EPP) or other foamed materials container aesthetics and value. And because the thermal insulation layer made of expanded polystyrene (EPS), expanded polyethylene (EPE), expanded polypropylene (EPP) or other foamed materials is relatively easy to be damaged, especially, the user When using utensils to eat food in the container, because the setting of the inner liner layer can prevent the thermal insulation layer from being damaged and prevent accidental ingestion of the thermal insulation material, the container has the effect of protecting consumers' eating safety.

Also shown in Figure 3 and Figure 4 is Embodiment 2 of the label in-mold forming thermal insulation container of the present invention, the container includes:

Thermal insulation layer 1, which is made of expanded polystyrene (EPS), expanded polyethylene (EPE), expanded polypropylene (EPP) or other foam materials, and has been formed before the thermal insulation layer is formed It is foamed into granules for the first time, so when the thermal insulation layer 1 is molded in the molding mold, it actually belongs to the second foam molding;

The label layer 3, the label layer 3 can be pre-printed with various pictures, characters, colors or documents with various intentions to form a representation of the appearance of the container.

In the manufacturing process of the in-mold forming thermal insulation container with the label, the label layer 3 can be pre-placed in the forming mother mold 2 of the container (as shown in Figure 3), and when the thermal insulation layer 1 is formed, it can be combined with the label layer 3 at the same time. The above-mentioned label layer 3 is combined, and the above-mentioned label layer 3 and the thermal insulation layer 1 are integrally formed at the same time (as shown in Figure 4), so that the container can be provided with a decorative label on the outside, and the expansion of expanded polystyrene (EPS) can be improved. ), expanded polyethylene (EPE), expanded polypropylene (EPP) or other foamed materials for the aesthetics and value of containers.
