Description

Technical Field

[0001] The invention relates to a paper box, in particular to a paper box with a button-like connection structure, which can realize the hanging connection of multiple paper boxes. Background Art

[0002] There are various kinds of packaging on the market. While paying attention to the quality of the product itself, we should also pay attention to the packaging, because good packaging can not only protect the product to keep it hygienic and facilitate circulation and storage, but also enhance the product's aesthetic effect and improve its market competitiveness. It can also attract consumers' attention and increase their desire to buy. With the rising calls for environmental protection and low carbon, paper box packaging, as a material that is safer and more environmentally friendly than plastic, is gradually replacing plastic packaging.

[0003] For industries such as takeout, products need to be packed in multiple paper boxes, which are usually stacked up and placed in a plastic bag. This not only makes it easy for the multiple paper boxes to shake and become unstable, but also requires the use of plastic bags, which goes against the concept of environmental protection. Therefore, the market is in urgent need of a paper box packaging that can be easily connected. Summary of the invention

[0004] The purpose of the present invention is to provide a paper box with a button-like connection structure in order to overcome the defects of the prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A paper box with a button-like connection structure comprises a box body, the box body comprises a frame formed by four sequentially connected side panels and a bottom panel connected to the bottom ends of the side panels via folds, the upper parts of two opposite side panels of the box body are respectively provided with lock grooves, and the bottom panel connected to the two side panels is respectively provided with lock buckles; the lock grooves are composed of two vertical hollow grooves, the lock buckles are in a "cross" shape, and are composed of a turnover portion and two insertion tongues, the two insertion tongues are separated on both sides of the turnover portion, and the lock buckles are surrounded by tear lines arranged on the bottom panel and with both ends leading to the folds at the connection between the side panels and the bottom panel.

[0007] Preferably, the length of the hollow groove matches the length of the inserting tongue of the lock buckle.

[0008] Preferably, the distance between the two vertical hollow grooves of each lock groove is equal to the width of the flip portion of the lock buckle.

[0009] Preferably, a connection fold is provided at the connection between the two inserting tongues and the flip part of the lock.

[0010] Preferably, the four sequentially connected side panels consist of a front panel, a first side panel, a back panel and a second side panel connected in sequence, the bottom of the front panel is connected to the first bottom panel, the bottom of the first side panel is connected to the first side bottom panel, the bottom of the back panel is connected to the second bottom panel, and the bottom of the second side panel is connected to the second side bottom panel; when folded into a box body, the first side bottom panel and the second side bottom panel are located outside the first bottom panel and the second bottom panel, the lock groove is arranged on the first side panel and the second side panel, and the lock buckle is arranged on the first side bottom panel and the second side bottom panel.

[0011] Preferably, the box body further comprises a top plate arranged at the top end of each side plate through a fold.

[0012] A paper box assembly comprises a plurality of paper boxes connected in sequence from top to bottom, wherein two adjacent paper boxes are connected by a locking buckle of an upper paper box and a locking groove of a lower paper box.

[0013] Preferably, the hook connection between two adjacent paper boxes is achieved by separating the lock buckle of the upper paper box from the bottom plate along the tear line and folding the folding portion downward so that the inserting tongue is inserted into the lock groove of the lower paper box.

[0014] Preferably, among the multiple paper boxes connected in sequence from top to bottom, a handle is provided on the top of the box body of the topmost paper box.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) It is folded from cardboard, with ingenious design and easy processing.

[0017] (2) The present invention creatively uses a part of the bottom plate as a lock buckle and connects it through a tear line. It has a simple appearance, a simple structure, and is easy to use.

[0018] (3) Through the structure of the lock buckle and the lock groove of the present invention, when multiple paper boxes are combined to form a paper box assembly, the paper boxes can be prevented from shaking in the horizontal and vertical directions, and can also be conveniently lifted by the handle provided on the top paper box.

[0019] (4) In the paper box assembly, the stress-bearing part of the hanging connection is actually the vertical side panel, which is conducive to stability when lifting. BRIEF DESCRIPTION OF THE DRAWINGS
