Description

Packaging structure

This creation relates to a packaging structure; in particular, the creation relates to the structure of a packaging board.

In the process of the display panel, the glass plate is provided as a substrate via a thinning process. The batch of glass is packed, transported to the processing destination, finished thinning, then batched and finally transported to another destination for subsequent processing.

In general, the packaging material used to package the processed glass sheet may be the same as the packaging material used to process the front glass sheet. As shown in FIGS. 1A-1B, the packaging material 8 includes a casing 810 and an upper cover 820. The casing 810 and the upper cover 820 define an accommodation space for accommodating and protecting the glass plate. However, due to changes in the number of glass sheets, or the thickness of the glass sheets after processing, there is more room in the cabinet. Since the change of the accommodating space will affect the fixing and protection effect of the glass plate in the box, it is necessary to try to adjust the packaging on the extra accommodating space. The conventional compensation for the release of the accommodating space is to set the accommodating space in which the filling unit 90 is extra. However, this practice increases manufacturing costs, increases the packaging step, and increases the packaging step, which also increases the chance of errors, such as the loss of the filling unit 90.

It is an object of the present invention to provide a package structure having a housing volume having a variable volume.

Another object of the present invention is to provide a packaging structure which can reduce the amount of packaging material used.

The package structure of the present invention comprises a case and an upper cover. The upper cover is attached to the upper part of the box body and is enclosed with the box body to form an accommodation space. The upper cover comprises a frame and a first cover, wherein the frame encloses a hollowed out area and has at least one inner wall facing the hollowed out area. Furthermore, a plurality of support protrusions respectively protrude from the at least one inner wall surface toward the hollow area, and the adjacent support protrusions are spaced apart from each other by a gap. The first cover is disposed in the hollow region and has at least one end surface opposite to the at least one inner wall surface. Furthermore, a plurality of protrusions respectively protrude from the at least one end surface. When the first cover is in the first position, the protrusions are respectively overlapped on the support protrusions; when the first cover is in the second position, the protrusions respectively fall into the gaps, so that The first cover plate sinks into the accommodating space more than when it is in the first position. Therefore, the distance between the first cover and the bottom of the case is variable, and the accommodating space enclosed by the upper cover and the case can be restricted for different items having different lengths in the direction in which the upper cover is closed with respect to the cover.
