TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging, in particular to a balanced paper box. BACKGROUND

[0002] The paper box as a common packaging container is widely used in the food industry, especially in the fast food and take-out field. With the increasing demand of consumers for dining experience, how to design a paper box that is both convenient and practical and innovative has become the focus of the industry.

[0003] Currently, fried chicken, chicken nuggets and other snacks are usually equipped with various flavors of sauce. When consumers choose multiple sauce boxes, it is inconvenient to take the meal, and the sauce is easy to mix up or unstable when dipping, resulting in a poor dining experience. To this end, the prior art provides a paper box that can be used to assemble multiple sauce boxes to reduce the possibility of dipping sauce confusion. However, after the meal is over, it is basically discarded, and the use time and frequency are relatively short, and it is relatively not environmentally friendly, so further improvement is needed.
