The present invention is to solve the problem that there is no heat insulation function in the conventional paper or plastic container to provide heat insulation, heat insulation, burn prevention and reinforcement effect to various paper or vinyl containers such as cups, bowls, plates, lunch boxes and various packaging containers to be.

The present invention is a manufacturing method and product of a container having a kind of heat insulating layer, mainly mixed with liquid adhesive and heated foamed particle powder to form a composite paint, and can also be applied to the outer surface of the target by adding a pigment and the surface layer by heating It can be combined with the foam layer and can also be applied using a pattern mold to form a three-dimensional pattern on the surface, which is a kind of various aesthetics, thermal insulation and thermal insulation and burn prevention effect.

In general, containers generally use paper or vinyl in consideration of cost and universality of use. Examples include paper or vinyl cups, bowls, plates, packaging containers made from these materials, and thermal and lunch boxes.

Paper containers cannot provide thermal and thermal insulation with a single surface layer, and are used once when discarded in two layers or when forming an isolation layer, which is expensive and cannot be put into practical use. Vinyl containers also have a single layer, which does not have insulation and insulation effects, and the surface of paper or vinyl containers only prints for aesthetics only, and has no three-dimensional pattern effect. The paper cups currently used can prevent burns by using plastic pedestals to prevent burns, but the inconvenience of using pedestals when using them, and after use, the paper cups must be discarded and the pedestals must be stored separately. Weakens the sex.

An object of the present invention is to prepare a composite paint continuously by mixing heated foamed particle powder into a liquid adhesive, and to apply it to a predetermined range of paper or to the surface of various molded containers, and to apply a coating paper or container. The foamed particles on the surface produce a foaming action while the liquid adhesive adheres to the surface of the paper or the container to form a layer of foam on the surface of the paper or the container. By cutting the paper thus produced to manufacture a variety of containers or used on the surface of the paper or vinyl container has an insulating effect, so that the user does not have a hot sensation when the hot material is contained in the container has the effect of thermal insulation and insulation and burn prevention.

After the pigment is added to the composite paint according to the present invention and sprayed or applied using a roller, the paint-coated pattern is heated to form a three-dimensional pattern which protrudes by the foaming action or after the three-dimensional pattern is formed, color printing is performed again. In addition, the three-dimensional pattern that protrudes at the same time also has a thermal insulation function when held by hand, which provides aesthetics as well as heat insulation, heat insulation, and burn prevention.

The present invention can be used on the surface of various paper containers or vinyl containers to form various three-dimensional patterns according to the mold of the design to provide aesthetics and at the same time provide an image protection effect of the protruding pattern.

The degree of protrusion of the three-dimensional pattern described above can be controlled within the thickness of the coating material and the heating temperature of 80-160 ° C. to obtain the required degree of protrusion of the pattern.

The present invention mainly mixes the heated foamed particle powder in a liquid adhesive and then continuously prepares the composite coating by coating method, which is applied to a predetermined range of paper or the surface of various shaped containers and heats the paper or the container again. The heated foam particles on the surface create a foaming action, and at the same time the liquid adhesive adheres to the surface of the container to form a layer of foam on the surface. The paper is thus cut to form the container or applied to the surface layer of the container. It is applied to the surface of paper or vinyl containers to form a layer of heat insulation layer so that when a user using the container holds it by hand when holding a hot substance in the container, there is no hot sensation and there is a warming action. In addition, by using a pattern mold on the surface layer, the pigment is added to the composite paint and sprayed or stamped with a roller to form a colored three-dimensional pattern in which the pattern of the pattern protrudes by foaming after heating, or color printing after the three-dimensional pattern is formed. It can produce various aesthetic visual effects, and at the same time, the three-dimensional pattern that protrudes can provide a variety of functions such as aesthetics, thermal insulation, insulation, and burn prevention.

In the method for producing a heat insulating layer container according to the present invention, the heated foamed particle powder (2) is added to the liquid adhesive (1) of FIG. 1 to form the mixing mixture (3), and then the composite paint (4) is formed and applied in a manner of application. The composite paint 4 is semi-finished 6 (e.g., FIG. 2A) or a container 7, (using a machine comprising a spray device 5, a roller device 5 'and a color printing device 5``). 7`) (e.g., Figs. 2B-2C or 3A-3C) and again heat the vessels 7, 7` through the heating device 8 to form heated foamed powder on the surface of the vessel ( 2) This foaming action is produced and at the same time, the liquid adhesive 1 attaches the foam layer to the surface layers of the containers 7 and 7` and forms the foam layer 9 (e.g., FIG. 4A) on the surface layer to reinforce the effect. At the same time provide heat insulation and warming effect.

The liquid adhesive 1 may be water-soluble or oil-based, and both have a coagulation adhesive action in the heating foaming process.

As shown in Fig. 1 and Fig. 2, the composite paint 4 is set on the roller 51 'of the roller device 5' through a design mold directly set on the roller 51 'of the roller device 5'. By rotating the design mold, the composite paint 4 is printed on the continuous printing paper P of the continuous reel-type paper P` with the design mold, and cut according to a previously designed portion to cut the semi-finished product 6 of the container 7 (for example, 2a) is made and molded back into the container (not stated as it is not the subject of the invention) and then the container 7 (7 ′) is heated to form a layer of foam layer 9 on the outer surface of the container. Let's do it.

1 and 2 and 4, when the method is applied to the surface layer of the paper container 7 or the pre-injection-molded vinyl container 7`, a thermal insulation effect of one layer is formed to allow the user to contain hot materials. It doesn't feel hot and also provides warmth. In addition, a design mold may be used for the surface layer as shown in FIGS. 3A to 3C, and the composite paint 4 sprayed with the above-described composite paint or applied to the patterned portion using a roller device (FIGS. 1 and 2) is heated. After heating with the device, the foaming action is generated to form the protruding three-dimensional patterned foam layer 9, and at the same time, the protruding pattern provides a thermal insulation effect to achieve various aesthetics and effects of thermal insulation, thermal insulation and burn prevention.

1 and 2a to 2c and 3a to 3c and 4a to 4c, the composite paint 4 is applied to the container 7 and 7 'within the holding position and range of any part of the container. Forming the container without applying the entire surface (for example, FIG. 4C) allows the appropriate portion of the portion to be pitted, and then the composite paint 4 is applied to the recessed portions 71 and 71` so that the composite coating 4 is applied. By heating and foaming and filling the recessed portions 71 and 71 ', the outer surface of the containers 7 and 7' can be restored to a flat state, and thus the insulating portion can be cut at a portion to reduce the manufacturing cost.

1 and 3A to 3C and 4A to 4C, the pigment 11 may be added to the composite paint 4 so that a colored pattern may be formed at the foamed position. (7) After applying and foaming to the surface of (7`), the color printing apparatus 5 "is again applied to the foaming position of the foam layer 9 (FIGS. 4B, 4C) or the entire foam layer 9 (FIG. 4A). Proceed to see the colorful pattern.

The protruding degree of the three-dimensional pattern can obtain the protruding thickness after foaming of the required pattern at the heating temperature of 80-160 ° C.
