Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-6 , a variable-volume and easily decomposable corrugated paper carton provided by the present invention includes a corrugated paper box body 1 and a cardboard cover 4. Both sides of the top end of the corrugated paper box body 1 are fixedly connected with cardboard covers 4. The inner side wall of the corrugated paper box body 1 is fixedly connected with kraft paper 5. The adjustment structure 6 is fixedly connected to the bottom end inside the corrugated paper box body 1. The adjustment structure 6 includes a spacer cardboard 601, a first side plate 602, and a second side plate 603. The spacer cardboard 601 is fixedly connected to one end inside the corrugated paper box body 1. One end of the spacer cardboard 601 is fixedly connected with the first side plate 602. The other end of the spacer cardboard 601 is fixedly connected with the second side plate 603. A plurality of spacer cardboards 601 are fixedly connected to the bottom end inside the corrugated paper box body 1, and the plurality of spacer cardboards 601 are evenly distributed at equal intervals at the bottom end inside the corrugated paper box body 1.

[0026] Refer to the attached Figure 2 , Figure 5 and Figure 6, when using this corrugated paper carton, place the items to be packaged inside the corrugated paper box body 1, then cover the cardboard cover 4 and seal it with tape. Since the inner wall of the corrugated paper box body 1 is covered with a layer of kraft paper 5, the inside of the corrugated paper box body 1 has a good waterproof effect, making this corrugated paper carton have a good packaging effect. Moreover, this carton made of corrugated paper is easy to decompose and recycle when being recycled. When using this corrugated paper carton, to prevent the items it packages from being fragile and easily damaged by bumps, a foldable spacer board 601 is fixed at the bottom of the corrugated paper box body 1. The spacer board 601 and its two side first side boards 602 and second side boards 603 on both sides can be selectively unfolded according to the actual size of the packaged items, so that several independent spaces are formed after unfolding, so that the items packaged in this corrugated paper carton are spaced from each other. At the same time, when the packaged items are heavy or there are certain sharp objects at the bottom, the spacer board 601, the first side board 602 and the second side board 603 can be folded and stored at the bottom inside the corrugated paper box body 1, so as to increase the bottom thickness of this corrugated paper carton, thereby greatly improving the packaging range of this corrugated paper carton.

[0027] Auxiliary structures 2 are provided at both ends of the corrugated paper box body 1. The auxiliary structure 2 includes a slot 201, a retaining piece 202 and a sealing strip 203. The slot 201 is opened inside both ends of the corrugated paper box body 1. A retaining piece 202 is fixedly connected to the top end inside the slot 201.
