DETAILED DESCRIPTION

Examples will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following illustrative examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with aspects of the present disclosure as detailed in the appended claims.

It should be noted that in this article, the terms “include,” “includes” or any other variations thereof are intended to mean non-exclusive inclusion, so that a process, method, article or device including a series of elements not only those elements and also includes other elements not expressly listed or elements inherent in a process, method, article, or device. Without further limitation, provided by the statement “includes an element . . . ” does not exclude the inclusion of the identical element in the process, method, article or device. In addition, there are components with the same names in different examples of the present disclosure. Characteristics and elements may have the same meaning or may have different meanings, and their specific meanings must be based on their context. The explanations in the specific examples may be further determined in conjunction with the context of the specific examples.

It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be called the second information, and similarly, the second information may also be called the first information. Depends on the context, as used here the word “if” can be interpreted as “at” or “when” or “in response to determination”. Furthermore, as used in this application, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context dictates otherwise. It should be further understood that the terms “comprising” and “including” indicate the presence of stated features, steps, operations components, assemblies, items, categories, and/or groups, but not to the exclusion of the existence, occurrence, or addition of one or more operations, elements, components, items, categories, and/or groups. The words “or” and “and/or” are to be construed as inclusive or to mean any one or any combination. Therefore, “A, B or C” or “A, B and/or C” means “any of the following: A; B; C; A and B; A and C; B and C; A, B and C”. Exceptions to this definition only occur when the combination of elements, functions, steps or operations inherently interact with each other are mutually exclusive in some manner. In describing the structure of a component, when referring to a layer or area is said to be “on” or “above” another layer or area, it can mean that it is directly located on another layer or another area, one area contains other layers or areas on top of it, or between it and another layer or area. And if the part is turned over, that layer, one area, will be “beneath” or “below” another layer, another area. In some examples of this disclosure, “B corresponding to A” means that B is associated with A and B can be determined according to A. But it should also be understood that determining B based on A does not mean determining B based solely on A, B can be determined based on A and/or other information.

It should be understood that the specific examples described here are only used to explain the present disclosure and are not used to limit this disclosure.

In the following description, suffixes such as “module,” “component” or “unit” used to represent elements are used. The suffixes are only used to facilitate the description of the present disclosure and have no specific meaning in themselves. Therefore, “module,” “component” or “unit” can be used mixedly.

The packaging box usually only has basic packaging functions. After opening the packaging box, there are usually three ways of subsequent utilization. Most packaging boxes are for one-time use, and after being opened, the packaging boxes will be abandoned and become packaging waste, which is likely to cause environmental pollution or resource waste. Part of packaging boxes are also for one-time use. Although the opened packaging boxes are also discarded, the materials used to make them will be recycled. This will also cause certain pollution and waste of resources. There are also some packaging boxes that can be reused. But it is basically still used for packaging, so its reuse is subject to certain limitations.

In view of the above analysis, the present disclosure provides a packaging box and cardboard structure. In the present disclosure, cardboard may refer to any paper-based material including paperboard. The packaging box includes a first box body and the second box body. In the first state, the second box body is loaded into the first box body, and the packaged items may be placed in the first receiving part and the second receiving part of the second box body, so that the first box body and the second box body may provide double layer of protection for packaged items. In the second state, the second box may be taken out from the first box and bent to connect to the first plate body of the first box body, so that the first receiving part, the second receiving part and the first opening can hold and display the packaged items, making it convenient to access and store the packaged items during use. Packaging box has a variety of functions and can be used in a variety of scenarios, expanding the application scope of packaging boxes, thereby making the packaging box easier to reuse and more environmentally friendly.
