Problems solved by technology

[0004] Due to the change of the material of the existing heavy-duty packaging cartons, the bearing capacity of the bottom of the packaging box is limited. Usually, pallets are selected to improve the compressive strength and bearing capacity of the bottom of the packaging box. After adding the bottom tray, the structure becomes complicated, which increases the difficulty of processing and cost, the shaking and tumbling during transportation may easily cause the pallet and the main box to loosen or even fall off, which affects the use effect of this type of packaging box and cannot meet the technical requirements of heavy-duty packaging

Embodiment 1

[0025] Such as figure 1 and figure 2 As shown, the non-pallet heavy-duty packaging carton of this embodiment includes a square tubular outer box body 1 and two U-shaped plugs 2 for sealing the openings at both ends of the outer box body 1, and the U-shaped plugs 2 pass through the latches 3 It is fixed at the openings at both ends of the outer box 1. The packaging carton is easy to manufacture, low in cost, and has less leftover material. It can play a better load-bearing effect and save space without a tray at the bottom. The four sides of the outer box 1 Both surfaces can be used as the bottom surface. Even if there is a rollover during the transportation process, it will not affect the packaging effect of the packaging carton. The U-shaped plugs 2 at both ends are fixed by the bolts 3, which can be easily installed and disassembled, and it is convenient to load or take out products. , reusable, convenient and flexible to use.

[0026] In this embodiment, the U-shaped plu...

Embodiment 2

[0034] The non-pallet heavy-duty packaging carton of this embodiment is basically the same as that of Embodiment 1, the main difference is that, as image 3 As shown, in this embodiment, the U-shaped plug 2 is arranged in the openings at both ends of the outer box body 1. The U-shaped plug 2 includes a plug bottom surface 21 and plug side surfaces 22 vertically connected to both sides of the plug bottom surface 21. The top surface of box body 1 is provided with the 3rd bolt hole 12, and the plug side 22 on one side is provided with the 4th bolt hole 24 that cooperates with the 3rd bolt hole 12, between the 3rd bolt hole 12 and the 4th bolt hole 24 There is a pin 3 inserted through it, and the U-shaped plug 2 plays a vertical support role in the outer box body 1 while leaving a gripping position for manual lifting to facilitate manual handling. The top surface is fixed and connected by the pin 3. The connection method has few openings, and the pressure in the vertical direction...

Abstract

The invention discloses a heavy packaging carton. The tray-free heavy packaging carton comprises a square tubular outer carton body and two U-shaped plugging heads used for plugging openings in the two ends of the outer carton body, wherein the U-shaped plugging heads are fixed to the openings in the two ends of the outer carton body through bolts. The tray-free heavy packaging carton is simple instructure, convenient and flexible to detach and install, capable of being repeatedly used for many times, low in manufacturing cost, and high in bearing and anti-pressure capacity.

Description

technical field [0001] The invention relates to the field of packaging boxes, in particular to a pallet-less heavy-duty packaging carton. Background technique [0002] The existing heavy-duty packaging technology usually uses wooden boxes. At present, my country has become the world's second largest wood consumer and the largest wood importer. The country has issued a ban on logging. By 2017, all commercial logging of natural forests will stop, the external dependence of wood consumption is close to 50%; however, with the rapid development of my country's logistics industry, the demand for heavy-duty packaging will continue to increase, the contradiction between the ecological environment and business needs will become more prominent, and the field of heavy-duty packaging technology will There will be various challenges. [0003] In order to solve the above contradictions, the heavy-duty packaging technology of "replacing wood with paper" has appeared on the market. This is o...
