Detailed Description

The spirit of the present disclosure will be apparent from the accompanying drawings and detailed description, and any person skilled in the art who knows or who can comprehend the teachings of the present disclosure may make changes and modifications without departing from the spirit and scope of the present disclosure.

As used herein, the terms "comprising," "including," "having," "containing," and the like are intended to be open-ended terms that mean including, but not limited to.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.

Relative terms, such as "lower" or "bottom" and "upper" or "top," may be used herein to describe one element's relationship to another element as illustrated in the figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one of the figures is turned over, elements described as being on the "lower" side of other elements would then be oriented on the "upper" side of the other elements. Thus, the exemplary term "lower" can include both an orientation of the "lower" and "upper" depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. Thus, the exemplary term "below" or "below" can encompass both an orientation of above and below.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present invention and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

FIG. 1 is a schematic top view of a packaging system 10 according to one embodiment of the present invention; fig. 2 is a schematic perspective view of the packaging system 10 in a flat state according to an embodiment of the present invention; FIG. 3 is a schematic top view of the packaging system 10 after the first fold is made according to one embodiment of the present invention; fig. 4 is a perspective view of the packaging system 10 in a first folded state according to one embodiment of the present invention. Fig. 2 and 4 correspond to fig. 1 and 3, respectively; that is, fig. 2 and 4 are schematic perspective views of fig. 1 and 3, respectively. Fig. 1 and 3 are different in that fig. 1 shows a state before the first folding B1 of the first stretch unit 160 (or the stretch unit 150) of the bottom plate 100 of the packaging system 10, i.e. a state without folding; fig. 3 shows the first stretch unit 160 of the bottom plate 100 of the packaging system 10 after the first folding B1. Fig. 2 and 4 are different in that fig. 2 shows a flat state of the bottom board 100 of the packaging system 10 before the first bending B1 is performed (when there is no bending), and fig. 4 shows a first folded state of the bottom board 100 of the packaging system 10 after the first bending B1 is performed.

As shown in fig. 1 and 3, the packaging system 10 includes a base panel 100; the base plate 100 includes a first block 110, a second block 120, and a first expansion part 160. The second block 120 is disposed at one side of the first block 110. The opposite ends of the first telescopic part 160 are respectively connected with the first block 110 and the second block 120; that is, the first block 110 and the second block 120 are respectively located at two sides of the first expansion part 160. The first block 110 and the second block 120 have an initial relative position relationship, as shown in fig. 1, the first block 110 and the second block 120 are connected by the first expansion part 160, and the first expansion part 160 has a first expansion part original length Ls10. When the first expansion part 160 is bent by the first bending B1, the relative positions of the first block 110 and the second block 120 are changed to generate a first relative positional relationship different from the initial relative positional relationship, as shown in fig. 3. That is, fig. 1 shows the initial relative position relationship of the first block 110 and the second block 120, fig. 3 shows the first relative position relationship of the first block 110 and the second block 120, as shown in fig. 3, the first block 110 and the second block 120 are connected by the first expansion part 160, and the first expansion part 160 has the first expansion part first length Ls11.

When the first stretching part 160 is bent by the second bending B2, the relative positions of the first block 110 and the second block 120 are changed to generate a second relative positional relationship different from the initial relative positional relationship and different from the first relative positional relationship, as shown in fig. 5. That is, fig. 5 shows the second relative position relationship of the first block 110 and the second block 120, and as shown in fig. 5, the first block 110 and the second block 120 are connected by the first telescopic part 160, and the first telescopic part 160 has the first telescopic part second length Ls12.
