The sub-storage body 12 has a second inner cavity 121. The second inner cavity 121 is formed by a cover 123 and a bottom board 122 that are arranged opposite to each other, and side walls 124 that are arranged opposite to each other. In this embodiment, the bottom of the container body 11 is further provided with an opening 112. The sub-storage body 12 can move into or out of the container body 11 through the opening 112, so as the switch between the extension position and the retraction position.
Specifically, referring to FIG. 1, the sub-storage body 12 is completely located inside the first inner cavity 111 of the container body 11, and in this case, the sub-storage body 12 is at the retraction position. Then, the first inner cavity 111 of the sub-storage body 12 forms a first main storage portion of the storage unit 10, and objects can be stored in the first storage portion. A boundary of the first main storage portion is completely defined by a boundary of the sub-storage body 12. The cover 123 of the sub-storage body 12 forms a top wall of the first main storage portion.
In another embodiment, the sub-storage body may be partially located inside the first inner cavity of the container body. In this case, the first main storage portion is formed by the cover of the sub-storage body, partial side walls located in the first inner cavity, and cavity walls of the first inner cavity of the container body. That is, when the sub-storage body is partially located inside the first inner cavity of the container body, a part of the boundary of the first main storage portion is defined by the boundary of the sub-storage body.
Referring to FIG. 3 and FIG. 2, the sub-storage body 12 moves to the outside of the container body 11 through the opening 112 on the container body 11. In this case, the sub-storage body 12 is at the extension position, and the cover 123 of the sub-storage body 12 seals the opening 112 of the container body 11. Then, cavity walls 113 of the first inner cavity 111 of the container body 11 and the cover 123 of the sub-storage body 12 form a second main storage portion of the storage unit 10. The second storage portion is located inside the container body 11. The second inner cavity 121 of the sub-storage body 12 forms an extended storage portion of the storage unit 10. The extended storage portion is located outside the container body 11.
