Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, specifically relating to a recyclable and environmentally friendly cardboard box. Background Technology

[0002] Cardboard boxes, as a common and widely used packaging container, are ubiquitous in our daily lives and business activities. They are mainly made of folded, glued, or bound cardboard, typically featuring a hexagonal structure, including a top opening for filling, four side walls providing protection and support, and a flat bottom to bear the weight of the contents. In today's booming era of logistics and e-commerce, the use of cardboard boxes in the packaging industry has experienced explosive growth. While traditional cardboard boxes are widely used, they have revealed many drawbacks and urgently need innovation.

[0003] Problems with existing technology:

[0004] The volume of traditional cardboard boxes cannot be changed once it is determined. In logistics and warehousing scenarios, fixed-volume cardboard boxes often result in wasted space when dealing with goods of different sizes and heights. For example, small items are packed into large cardboard boxes, leaving a lot of empty space inside. This not only increases warehousing costs, but also makes the items prone to damage during transportation due to the large gaps in the space, reducing transportation safety and the rate of goods remaining intact. Utility Model Content

[0005] The purpose of this invention is to provide a recyclable and environmentally friendly cardboard box that can flexibly adjust its volume according to the height and size of the contents, effectively secure the contents, and provide good cushioning protection.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A recyclable and environmentally friendly cardboard box includes a first box body, a first opening at the top of the first box body, a bottom plate integrally formed at the bottom of the first box body, a vertically adjustable second box body inside the first box body, a second opening at the bottom of the second box body, multiple telescopic straps arranged vertically on both sides of the interior of the second box body, two top plates connected to each other between the outer walls of the multiple telescopic straps on the same side, an insert piece integrally formed on the other side of the top plate, multiple third fixing slits equidistantly arranged on the two inner sides of the second box body to cooperate with the insert piece for adjusting the spacing of the telescopic straps on both sides, an inner flap integrally formed on both sides of the top of the second box body, and an outer flap integrally formed on both sides of the top of the second box body perpendicular to the inner flap.

[0008] The first box has multiple first fixed cuts arranged vertically at equal intervals on its four sides, and the first fixed cuts are integrally formed with the first box. The top four sides of the first box are integrally formed with connecting straps, and the other end of the connecting straps is integrally formed with a hanging piece that cooperates with the first fixed cut. The two boxes have two second fixed cuts integrally formed on their four sides and above the first box. One end of the connecting strap passes through the second fixed cut and the hanging piece is locked onto the corresponding first fixed cut.

[0009] A zipper is provided between the two outer covers on both sides.

[0010] The base plate has multiple first buffer slots arranged in an equidistant array inside.

[0011] The inner flap has multiple second buffer slots arranged in an equidistant array.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This invention allows for flexible adjustment of the container's volume by adjusting the height of the second container within the first container, and by utilizing connecting straps and hanging plates in conjunction with the first and second fixed cutouts. This improves space utilization and better accommodates loads of different heights. The wavy, telescopic strap effectively prevents large gaps between the load and the inner wall of the container, eliminating the need for additional fillers and enhancing the stability of the load. All components are integrally molded from recyclable cardboard, reducing production costs. The first and second buffer grooves within the bottom plate and inner flap provide excellent cushioning protection for the load during transportation, reducing the risk of damage.
