Method for manufacturing insulated cup structure

The invention relates to a method for manufacturing a heat insulating cup structure, in particular to a method for using the prior art to make the heat insulating cup sleeve have a curling portion, and the cup body and the heat insulating cup sleeve can be sleeved, and the single side or the double side can be utilized. The curling edge portion forms an insulating gap between the insulating cup sleeve and the corresponding surface of the cup body, thereby achieving the effect of improving the heat insulation effect and better heat preservation property, thereby improving the quality and convenience of the user to hold or taste the beverage. In addition, the use of the unilateral crimping portion allows the insulation structure to be more compact, so as to reduce the stacking space during the transportation and packaging of the insulated cup sleeve, thereby reducing the cost of packaging and transportation.

According to the current, portable drinks such as coffee, juice, pearl milk tea and various tea drinks are extremely popular. However, based on the convenience of carrying and cost considerations, the current portable drinks are generally packed in paper cups; however, Because the paper beverage cup not only has poor heat insulation effect, it is easy to burn, and the heat insulation function is quite poor. If the consumer does not finish drinking as soon as possible, as long as the cold or warm drink is refreshed, it will quickly return to the temperature. At room temperature, it seriously affects the taste and flavor of the drink.

Therefore, a related manufacturer has developed a heat-insulating cup sleeve which is arranged on the outer side of the cup of the paper cup, and when used, the cup body can be directly inserted into the heat-insulating cup sleeve, thereby achieving the effect of heat insulation. However, when the conventional insulated cup cover is combined with the cup body, the inner side surface is combined with the cup body without any heat insulation space, so that the general user can insulate the beverage when taking the beverage. The effect will be greatly reduced, of course, the effect of its insulation will also Because there is no gap between the cup body and the heat insulating cup sleeve, there is also a corrugated paper insulating cup sleeve, which can be insulated from the cup body by the wave pattern on the inner side. However, the wave insulation can achieve a very small heat insulation effect, and since the corrugated paper itself has a two-layer structure, if the ink is to be printed on the surface, it is more difficult to print, and it is easier to cause the cup to be dirty due to poor printing. Therefore, it is necessary to attach it separately during printing, which results in a very high production cost, and thus it is necessary to improve it.

Accordingly, another related art has developed an insulating outer layer disposed on the outer surface of the cup body, and the insulating outer layer has a joint portion, an inner fold portion extending downward from the joint portion, and a cup formed on the cup. An insulating space between the outer surface and the inner surface of the insulating outer layer; the outer surface of the cup may be attached to the insulating outer layer, and the insulating outer layer is separated from the cup body Hot space, but has the effect of blocking heat source conduction. However, when the above-mentioned heat-insulating outer layer is combined with the cup body, the upper end is coupled to the underside of the cup edge so that the upper half thereof is almost in contact with the cup body, and the general user is accustomed to taking the beverage when taking the beverage. In the upper part, the heat insulation effect of the conventional use is also greatly reduced. Of course, the effect of heat preservation is also affected by the fact that there is no positive gap between the cup body and the heat insulating outer layer. Therefore, the conventional insulated cup cover does have The need to improve.

In addition to the above-mentioned insulation structure, a related manufacturer has developed a rib disposed between the outer surface of the cup body and the inner surface of the heat insulating cup cover; the rib can be used to form a surface between the cup body and the inner surface of the heat insulating cup cover. It has insulation gaps, which can improve the heat insulation effect, have better heat preservation and increase the stiffness of the cup sleeve. However, the above-mentioned conventional heat insulating structure is designed to protrude a plurality of ribs on the outer edge of the cup body or the inner surface of the heat insulating cup sleeve, so that the ribs must be formed on the outer edge of the cup body or not only through the processing action during manufacturing. Insulating the inner surface of the cup sleeve, and increasing the complexity and cost of the paper cup or the heat insulating cup sleeve, and whether the rib is formed on the outer edge of the cup body or the inner surface of the heat insulating cup sleeve, Paper cups or insulated cups cannot be stacked and stacked, which leads to increased space and cost of packaging and shipping. Therefore, the general practitioners cannot meet the needs of the user in actual use.

The main object of the present invention is to overcome the above problems encountered in the prior art and to provide a heat-insulating cup sleeve having a beading portion by using the prior art, and the cup body and the heat insulating cup sleeve can be sleeved, and a single side is utilized. Or the edge of the bead can make the heat-insulating cup sleeve can be easily engaged on the cup body without using the adhesive of the adhesive, and become a double-layer cup, and the heat-insulating cup sleeve corresponds to the cup body. The surface is formed with an insulating gap to enhance the heat insulation effect and to have better heat retention effect, thereby improving the quality and convenience of the user to hold or taste the beverage, and in addition, using the unilateral crimping portion setting The insulation structure can be made more compact to reduce the stacking space during the transportation and packaging of the insulated cup sleeve, and to reduce the cost of packaging and transportation.
