Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a left-right sealed and folded PDQ packaging box. Background Art

[0002] Carton packaging has the characteristics of easy material acquisition, light weight, easy printing, easy design and molding, and low cost. It is widely used in sales packaging and transportation packaging of goods. PDQ packaging box, which means "product quick display box", is a packaging box designed for rapid assembly and display of goods. It has the characteristics of rapid molding and assembly and stable stacking. At present, although the existing PDQ packaging box molding cardboard meets certain support and stacking functions, its cardboard presets are relatively complex and the molding process is also relatively cumbersome. For example, the carton structure with patent number CN216469076U has a relatively complex cardboard processing, resulting in a low molding process efficiency. The strength of the final carton structure will also be affected to a certain extent, and cannot well meet the functions of rapid molding, transportation, and stacking and display.

[0031] Reference Figure 3 , Figure 4 The first strip paperboard 13 and the first U-shaped paperboard 12 are folded on the side of the box body 5 to form the rear support leg 4, and the second strip paperboard 221 and the first U-shaped paperboard 12 are folded on the side of the box body to form the front support leg 3.

[0032] Reference Figure 2 , Figure 3 The first U-shaped paperboard 12 includes a first horizontal strip 121 connected to the bottom paperboard 10 and first vertical strips 120 located at both ends of the first horizontal strip 121. The first vertical strips 120 at both ends are respectively in contact with the first strip paperboard 13 and the second strip paperboard 221 to form a double-layer paperboard.

[0033] Reference Figure 3 A third U-shaped paperboard 21 which can be folded downward to the left and right sides of the box body 5 is provided on both sides of the main paperboard 20. The third U-shaped paperboard 21 includes two third vertical strips 210 connected to the main paperboard 20 at the upper end, and third horizontal strips 211 respectively connected to the lower ends of the two third vertical strips 210. The third vertical strips 210 are bonded to the first vertical strips 120, and the third horizontal strips 211 are bonded to the first horizontal strips 121.

[0034] Further, the box body 5 is mainly formed by folding and bonding the first paperboard 1 and the second paperboard 2. The left and right sides of the box body 5 are formed into a double-layer structure with the first U-shaped paperboard 12 through the first strip paperboard 13 and the second strip paperboard 221. Specifically, refer to Figure 2 , Figure 3The first vertical strip 120 is in contact with the first strip paperboard 13 and the second strip paperboard 221 respectively to form a double-layer paperboard structure. Glue is applied to the lower side of the first U-shaped paperboard 12, and after being folded up, it is bonded and fixed to the third U-shaped paperboard 21 folded down, so that the front and rear supporting feet form a supporting structure with three layers of paperboard on the side. When the box body 5 is stacked up and down, it has better strength and stability; on the other hand, the box body 5 is formed by folding and bonding two pieces of paperboard, which simplifies the complexity of design and molding compared to the design and folding molding of a single piece of paperboard, and the material utilization rate of the paperboard is also higher.

[0035] Each cardboard component in the design, such as the first U-shaped cardboard 12, the second U-shaped cardboard 22, and the third U-shaped cardboard 21, is assembled in a folding manner, and only glue needs to be applied once on the lower side of the first U-shaped cardboard 21, which not only simplifies the production process and facilitates users to assemble quickly, but also the bonding method can ensure the stability of the box body.

[0036] Reference Figure 3 , Figure 4 The main paperboard 20 is a square board, and triangular paperboards are arranged at its four corners. The triangular paperboards are respectively located on the top of the rear supporting foot 4 and the front supporting foot 3 to form a plane supporting plate 23.

A cut line 202 is provided at the connection between the main paperboard 20 and the triangular paperboard. After the cutting line 202 is cut, the main paperboard 20 is folded and fixed toward the back paperboard 11.

[0038] Further, after the left and right sides of the box body 5 are bonded and formed, the top surface of the box body 5 is the main paperboard 20, and the four corners of the main paperboard 20 naturally form a plane support plate 23. In order to improve the display effect of the box body 5, the top surface can also play a display role. The main paperboard 20 retains the paperboards at the four corners, and the main paperboard 20 is folded to the back paperboard 11. The four corner paperboards retained form a plane support plate 23 on the top of the front support leg 3 and the rear support leg 4 with the first U-shaped paperboard 12, the second U-shaped paperboard 22, and the third U-shaped paperboard 21 on the side and front of the box body 5.
