Paper container with unfoamed layer

This creation is related to paper containers, and in particular to a paper container having an unfoamed layer.

According to the general catering industry, dishwashing utensils are often used to hold food or beverages. The tableware made of plastic or styrofoam is low in manufacturing cost, but its non-recyclable problem will seriously harm the environment, in order to respond to environmental protection. Paper cutlery has been used in the market to replace plastic or styrofoam cutlery to avoid serious environmental problems. The biggest problem often encountered with paper containers is the problem of heat insulation. Users often wear paper containers that cannot be effectively insulated when they are filled with hot food. Some people will set them outside the container (such as coffee cups). A heat-insulating ring is used to achieve the heat insulation effect. Generally, the heat-insulating ring is mostly thick cardboard such as corrugated paper. Although it can be effectively insulated, the heat-insulating ring needs to be additionally set when used, so it is not convenient to use and the heat-insulating ring is not convenient. It slips easily and causes the container to fall. Therefore, a foaming container has been developed, which is coated with a heat insulating layer on the surface, and the heat insulating layer is firstly subjected to high temperature and high pressure treatment to foam to form a foamed layer having the partition of the foamed layer. The hot layer can have good thermal insulation capability, so that the consumer can avoid burns when holding the container containing hot drinks or hot food by the heat insulating layer of the container.

However, in such a conventional foaming container, the foaming layer has a foaming temperature of more than 100 degrees Celsius, and the heat insulating layer is additionally subjected to a heating process in order to smoothly form the foamed layer. Foaming, this process requires a lot of resources to complete, so it will greatly increase the manufacturing cost of the foaming container, which in turn will increase the selling price of the foaming container and increase the burden on the catering industry and consumers. There is a drawback that needs to be improved.

Therefore, it is necessary to provide a novel and progressive paper container having an unfoamed layer to solve the above problems.

The main purpose of the present invention is to provide a paper container having an unfoamed layer, wherein the paper container having the unfoamed layer has a lower foaming temperature, so that the process of heating and foaming does not need to be performed first, when the paper has not been issued. When the paper container of the foam layer is filled with a food or liquid having a relatively high temperature, the unfoamed layer starts to perform the foaming process by itself, and the container can be more insulated after the foaming of the unfoamed layer is completed. The effect is that the creation can significantly reduce the cost and time of manufacture compared to conventional foam containers.

To achieve the above object, the present invention provides a paper container having an unfoamed layer comprising a body and a heat insulating layer. The main body includes a bottom plate and a crotch portion. The bottom plate and the crotch portion define an accommodating space and an opening communicating with the accommodating space. The system comprises at least one paper layer. The heat insulating layer is at least partially screen printed on the outer peripheral surface of the crotch portion, the heat insulating layer includes at least one unfoamed layer, wherein the unfoamed layer comprises an aqueous acrylic resin portion, a foamed powder, and The aqueous auxiliary part, wherein the aqueous acrylic resin portion and the aqueous auxiliary part are integrally formed into a substrate, and the foamed powder is uniformly distributed in the substrate, and the unfoamed layer has a foaming temperature.
