Description

Packaging structure

Technical Field

The invention relates to the technical field of packaging, in particular to a packaging structure.

Background

The traditional packaging structure generally adopts additional structures such as an air inflation package, a paperboard liner and foamed plastic as a packaging buffering mode, and the buffering structures need to be independently assembled in the packaging manufacture, so that the manufacturing cost of the packaging is increased, and the difficulty is increased for production and assembly.

At present, the fashioned packaging structure of a page (the pad is same cardboard with the packing) has also appeared on the market, and independent cardboard can be made and be connected packing shell and inside buffer structure as an organic whole, and specific technological means be for turning over partial cardboard to the inside liner structure that is used for supporting the object of packing that forms of packaging structure can, with integrative packaging structure not only save material, also do not inferior to conventional additional use in the aspect of the cushioning effect aerify packing, cardboard pad, expanded plastics etc..

However, the packaging structure formed by one sheet on the market still has the defect that the internal packaging space is single. The packing structure has only one packing space inside, and when other parts exist in the packed object, the packing structure can not prevent the collision among a plurality of packed objects. For example, common electronic products are provided with accessories such as batteries, and the above patent does not design a position where other accessories such as batteries can be placed separately, and needs to add extra materials to fix and protect the products, which increases the packaging cost, thereby increasing the product cost.

Disclosure of Invention

To the problem among the above-mentioned prior art, this application has proposed a packaging structure, provides more spaces of placing on the fashioned basis of adoption one page cardboard, has satisfied the packing demand when being more than one by the packing thing under the condition that does not increase extra material.

The packaging structure comprises a shell assembly in a square box shape in a folded state and a liner structure integrally formed in the shell assembly, wherein the liner structure is divided into a first liner structure and a second liner structure from bottom to top.

In one embodiment, the housing assembly includes a bottom plate, a first side plate, a second side plate, a third side plate, a fourth side plate, and a top cover, the first side plate to the fourth side plate are perpendicular to the bottom plate and are sequentially connected around the bottom plate along a circumferential direction, the top cover is connected to a side of the first side plate away from the bottom plate, wherein, in the folded state, the first side plate and the fourth side plate are opposite, and the second side plate and the third side plate are opposite.

In one embodiment, the first liner structure comprises a first liner plate and a second liner plate which are connected to two sides of a first side plate, and a third liner plate and a fourth liner plate which are connected to two sides of a third side plate, wherein first positive and negative pressing structures are arranged on the first liner plate to the fourth liner plate;

first welt extremely the fourth welt is in all inwards roll up folding formation under the fold condition and is located the square columnar structure of casing subassembly inside four corners department, first positive and negative press structure to the columnar structure is inside folding sunken so that four form first holding chamber between the first positive and negative press structure, the height of first positive and negative press structure is less than the height of columnar structure.

The four first positive and negative pressing structures in the first liner structure form the first accommodating cavity, and when placed with a packaged object, the packaged object is in a suspended state by using the support of the first positive and negative pressing structures, so that external impact can be prevented from being directly applied to the packaged object, and the first liner structure can protect the packaged object in multiple directions when impacted.

In one embodiment, the second gasket construction includes first and second partition walls at the same height and fixedly attached at their ends, the first and second partition walls being formed by centrally opening the second and fourth side panels and extending toward the interior of the housing assembly perpendicular to the second and fourth side panels, respectively.

In this embodiment, the second liner structure formed by the first partition and the second partition is not only used for placing another packaged object, but also divides the second liner structure from the first liner structure below, and the cardboard used for the first partition and the second partition also has the function of preventing two packaged objects in the first liner structure and the second liner structure from colliding with each other.

In one embodiment, the ends of the first and second partition boards in the folded state are respectively a first connecting portion and a second connecting portion which are turned up 90 ° to a vertical state, and the first connecting portion and the second connecting portion are adhered to each other.
