Abstract: A carton includes a top casing and a bottom casing. The top casing includes plural first sidewalls and plural first tongue parts connecting to the first sidewalls. The first tongue stripes parts are used for fixing on the inner surfaces of the adjacent first sidewalls. The bottom casing includes plural second sidewalls and plural second tongue parts connecting to the second sidewalls. The second tongue parts are used for fixing on inner surfaces of the adjacent second sidewalls. The bottom casing further includes plural reinforcing pieces respectively connected to one of the second sidewalls. The reinforcing pieces are disposed at the outside of the second sidewalls. When the top casing is coupled to the bottom casing, the reinforcing pieces are utilized for filling the gap between the top casing and the bottom casing caused by the first tongue parts.

Abstract: A package structure for packing at least one object is provided. The package structure includes first package containers, second package containers, and a third package container. The first package container is a cuboid and has a receiving space for receiving the object and a plurality of side surfaces surrounding the receiving space. Each side surface has a gap connecting the receiving space and exposing an edge of the object. The second package container has a first side, a second side, and a second receiving space therebetween for receiving the first package container. The third package container includes a first component and a second component being detachable to each other. One of the first component and the second component has a locking tab, and the other one has a locking hole. The first component and the second component together form a receiving space to receive the second package containers.
