A package includes a main body and an impact buffer rib. The main body is configured to form a storage space to accommodate a packaged object. The impact buffer rib is disposed on a side of the main body and outside the storage space. The impact buffer rib includes root portions and a central portion. The root portions are both end portions of the impact buffer rib, couple to the main body, and have a first height. The central portion is between the root portions and has a second height larger than the first height.

A package unit includes: a base on which a packaged object is placed; a box that surrounds the packaged object; and a lid that covers the box such that a surface provided with an overlapping section where a sheet is folded and overlapped serves as a high impact resistance surface when the packaged object receives an impact.

A cushioning member includes a cushioning material arranged between a side surface of an object and an exterior box and a positioning member for positioning of the cushioning material with respect to the object. The positioning member includes a holding portion that holds the cushioning material, an engagement portion engaged with an upper surface of the object while the cushioning material held by the holding portion is located at a position set in advance in the side surface of the object, and a coupling portion that couples the holding portion and the engagement portion to each other.

A buffer member includes: a resin sheet welded in a bag-like shape; and a medium sealed in the resin sheet, wherein the resin sheet includes a plurality of buffer areas each having a shape extending longitudinally in a first direction and arranged adjacent to each other in a second direction orthogonal to the first direction, each buffer area of the plurality of buffer areas includes a first buffer chamber having a shape extending in the first direction, a second buffer chamber having a shape extending in the first direction and formed at a position separated from the first buffer chamber in the first direction, and a connecting flow passage connecting the first buffer chamber and the second buffer chamber.

A packaging apparatus includes: an inner box of which upper side is open and capable of storing a first object; an outer box capable of storing a second object and the inner box disposed on the second object, and having a pair of inner flaps and a pair of outer flaps; a protective portion formed in the inner box to protect the first object, the protective portion being disposed between the first object and a portion that is included in a facing portion of the pair of outer flaps and that does not overlap with the pair of inner flaps in a state where the pair of inner flaps and the pair of outer flaps are closed; and a pressing portion formed in at least any one of the inner box and the outer box to press the first object toward a bottom surface of the inner box.

A container box for storing a sheet feed cassette for an image forming apparatus, the cassette having side guides movable according to a size of a sheet stored therebetween, includes bottom and upper flaps and side surface portions. An upper flap is foldable along a first axis located along an upper edge of a side surface portion and including a first flap foldable along a second axis parallel to the first axis, and a second flap on the first flap to be foldable with the first flap and further foldable along a third axis parallel to the second axis. When the cassette is stored in the box and the upper flaps are closed, an edge of the first flap presses the cassette to suppress vertical movement of the cassette within the box, and the second flap is folded to suppress horizontal movement of the cassette within the box.
