As shown in fig. 1 and 4, the packaging carton 1000 further comprises a buffer box 3, and the buffer box 3 and the accommodating box 2 are vertically stacked in the accommodating cavity 10 of the outer box 1.

Wherein, in the chamber 10 that holds of outer box 1, buffer box 3 is placed in the below that holds box 2, plays 2 fastens the effect in holding chamber 10, and then guarantees to hold box 2 and do not produce in holding chamber 10 and rock.

As shown in fig. 1 and 4, the buffer box 3 includes a buffer bottom plate 31 and a buffer side plate 32, and the buffer side plate 32 is connected to the buffer bottom plate 31 and folded back to form a buffer cavity 30. The buffer base plate 31 is provided with a lifting portion 311 for lifting the buffer box 3.

Wherein, the buffer box 3 is formed by cutting and folding a paperboard. In the present embodiment, the buffer side plates 32 are four side plates distributed along four sides of the buffer bottom plate 31. The buffer side plate 32 is folded along the folding line of the buffer side plate 32 and the buffer bottom plate 31, and then forms the buffer cavity 30 together with the buffer bottom plate 31.

Since the buffer side plate 32 has a supporting function for the buffer bottom plate 31, and since the characteristics of the cardboard are known, the buffer side plate 32 provides a buffer function for the buffer box 3. Thus, when the buffer box 3 is placed below the accommodation box 2, a buffering action can be provided for the accommodation box 2.

It should be noted that, in the present embodiment, the buffer cavity 30 may also be used for placing the product to be packaged, thereby increasing the packaging efficiency of the packaging carton 1000.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
