Insulation and leakproof container structure

The present invention relates to a heat-insulating and leak-proof container structure, in particular to an effect that the heat insulating layer containing the hollow body can be used to reduce the volume of the container, reduce the transportation cost, and better the heat insulation effect, in particular, The connecting portion is used for adhesive inside and outside, which can effectively ensure that the heat-insulating and leak-proof container does not leak and can prevent the heat-insulating and leak-proof container of the hollow body from being crushed during bonding.

According to the paper, the paper containers which are relatively simple to use are usually not subjected to any surface treatment process, and only a single layer of paper is bonded to the shape of a paper cup, a paper bowl or a paper tray. Although the production is simple and the cost is low, only a single layer of paper is used. The material has a poorer heat insulation effect, so when it is used for high-temperature beverages, it has no heat insulation effect and is prone to burn accidents.

Therefore, several forms of insulated containers have been commercially proposed for holding hot liquids. An example of a heat insulating material heat insulating container is an example. The heat-insulating material insulated container used in the manufacture is coated with a material such as polypropylene (PP) or polyethylene (PE) as a heat insulating material on the surface of the container, and then the container and the heat insulating material are simultaneously baked. A material such as polypropylene or polyethylene is formed on the surface of the container to form a heat insulating layer. However, in the above-mentioned conventional use of polypropylene or polyethylene as the heat insulating material, since polypropylene or polyethylene is only a simple plastic material, when polypropylene or polyethylene is baked and heated, there is often a gap. The thermal effect is not good, and when the baking temperature is heated to 120 ° C, the polypropylene material will easily fall off, and the polyethylene will cause damage, so that the polypropylene After the insulating layer of the olefin or polyethylene is formed into a heat insulating layer, defects such as thinner thickness and poor heat insulating effect are usually produced; and the outer edge of the container after the baking process is filled with pores or irregular irregularities, and It is a disadvantage that causes the pattern or its color to be blurred or difficult to be printed.

Another type of insulated paper container is such that the outer side wall of the body member is completely surrounded by a sleeve of corrugated cardboard. However, the procedure for making such a container involves the additional steps of forming the corrugated sleeve and adhering it to the outer surface of the side wall of the body member, thus having many other disadvantages. First, text, graphics, or other symbols are printed on the surface of the wrinkle, and the resulting deformed text or pattern does not have a good aesthetic for the consumer. Secondly, the sleeve is adhered to the side wall of the body member by a method in which only the raised ridges are in contact with the side walls, but the weak side walls are easy to separate the two. Moreover, the structure has a plurality of raised ridges on the sleeve, and a plurality of annular flanges are manufactured in the manufacturing process, which is not only complicated in structure but also high in cost. Furthermore, the container having the sleeve of the embossed wrinkles is not suitable for stacking, so that a large storage space is required, resulting in an increase in the cost of packaging and shipping. In addition, if they are forcibly stacked on each other in order to reduce their space volume during transportation, the sleeve subjected to extrusion will compress the heat insulating space formed by the ridges, thereby affecting the heat insulating effect of the container.

In view of this, the existing insulated container has the advantages of poor heat insulation effect, low printability, large volume, and high transportation cost; therefore, the general practitioner cannot meet the needs of the user in actual use.

The main purpose of the present invention is to overcome the above problems encountered in the prior art and to provide a heat insulating layer with a hollow body to have a better heat insulation effect and good printability.
