Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a stackable and convenient packaging box for delivery. Background Technology

[0002] Packaging boxes are indispensable in logistics transportation and goods distribution. Most existing packaging boxes have limited functions, only providing basic storage. When stacked for transport, traditional packaging boxes lack effective fixing and support structures, making them prone to instability. This can cause the boxes to slip and get damaged during transport, thus compromising the safety of the contents.

[0003] While some packaging boxes attempt to achieve stacking functionality by adding structures, these structures are often quite complex, increasing manufacturing difficulty and cost. Furthermore, some boxes lack tight enough connections between adjacent boxes when stacked, easily creating gaps and compromising stacking stability. Therefore, developing a stackable and convenient packaging box is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing packaging boxes, such as insufficient tightness between adjacent boxes when stacked, which easily leads to gaps and makes it difficult to ensure the stability of the stack. Therefore, this invention proposes a convenient stackable packaging box for delivery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stackable delivery convenience packaging box includes a main body, the main body of which includes a bottom cardboard, a back cardboard and a front cardboard integrally formed on the top two sides of the bottom cardboard, and side cardboard integrally formed on the other two sides of the top of the bottom cardboard. The two side cardboards are located between the front cardboard and the back cardboard and are connected to each other. A top cardboard is integrally formed on one side of the top of the back cardboard, and an insert cardboard is integrally formed on one side of the top cardboard. Multiple cardboard protrusions are integrally formed on the bottom of the bottom cardboard, and a stacking assembly is provided on the top of the top cardboard. The stacking assembly includes multiple rectangular slots formed on the top of the top cardboard. The inner wall of the rectangular slots is integrally formed with triangular cardboard. When multiple boxes are stacked, the cardboard protrusions at the bottom are inserted into the rectangular slots of the upper boxes. The triangular cardboard fills the gap between the cardboard protrusions and the rectangular slots, making the stacking more stable.

[0006] In one possible design, the cardboard protrusions are all angled. The inclined setting facilitates the protruding cardboard to be guided into the rectangular groove and enhances the clamping effect.

[0007] In one possible design, an arc-shaped notch is provided at the top of one side of the front cardboard. The arc-shaped notch is designed to facilitate gripping by the operator to open or move the packaging box.

[0008] In one possible design, the top of the side cardboard is integrally formed with an extended cardboard. During packaging, the extended cardboard is unfolded to a horizontal position to provide support for the snap-fit ​​of the top cardboard.

[0009] In one possible design, a longitudinal cardboard is integrally formed on one side of the side cardboard, and a transverse cardboard is integrally formed between the two longitudinal cardboards, with the longitudinal cardboard located directly below the rectangular groove. When stacked, the longitudinal and transverse cardboard sections provide support for the protruding cardboard, enhancing stability.

[0010] In one possible design, the longitudinal and transverse cardboard sections form a support frame, improving the overall strength of the packaging box.

[0011] In one possible design, the triangular cardboard is a right triangle, with its inclined surface engaging with the convex inclined surface of the cardboard to fill the gap and increase friction.

[0012] In this application, when in use, the item is placed inside the bottom cardboard. At this time, the two extended cardboards are first laid flat, and then the top cardboard is snapped together. The insert cardboard is then inserted between the front cardboard and the top cardboard to cover the item inside, thus completing the packaging process. When stacking multiple packaging boxes, the multiple cardboard protrusions at the bottom can be engaged with the rectangular grooves on the top of the next packaging box. Since the sides of the cardboard protrusions are all slanted, multiple triangular cardboard pieces are pushed by the cardboard protrusions and fill the gaps between the cardboard protrusions and the rectangular grooves. The cardboard protrusions become tighter and tighter, and the vertical and horizontal cardboard pieces below can support the cardboard protrusions, ensuring the stability of the device and the strength of the packaging boxes.

[0013] Beneficial effects: This convenient stackable packaging box, through its stacking mechanism, allows multiple cardboard protrusions at the bottom to engage with the rectangular slots on top of the next box when multiple boxes are stacked. Because the sides of the cardboard protrusions are angled, multiple triangular cardboard pieces are pushed by the protrusions and fill the gaps between the protrusions and the rectangular slots, making the protrusions increasingly secure. This effectively ensures the stability of the stacked boxes, preventing slippage and damage during transportation due to unstable stacking, and protecting the contents.

[0014] The vertical and horizontal cardboard sections below support the protruding cardboard, further enhancing the stability of the device and increasing the strength of the packaging box, enabling it to withstand greater external forces and reducing the possibility of damage during transportation and stacking.

[0015] When packaging items, place the items inside the bottom cardboard, first lay the two extension cardboards flat, then snap the top cardboard together, and insert the connecting cardboard between the front cardboard and the top cardboard to cover the items inside, thus completing the packaging process. The operation is simple and convenient, improving packaging efficiency.

[0016] The curved notch at the top of one side of the cardboard front makes it easier for operators to grip when packaging or taking out items, further enhancing ease of use. Attached Figure Description
