Abstract

A packaging box includes a bending piece provided at an end part of the other end side of a tubular side plate of the packaging box, and pressed while being surrounded by a breakable line and a bending line so as to be broken and bent to the inside of the box along the breakable line. In the bending state, the bending piece is configured such that its distal end part is positioned at the other end side from a receiving area of an object to be packaged and inhibits movement of the object to be packaged to the other end side.

First claim

What is claimed is:

1. A packaging form using a packaging box, the packaging box comprising:
a tubular side plate that covers a periphery of an object to be packaged;
one end side-blocking plate that blocks an opening of one end side, which constitutes an outlet of the object to be packaged in the tubular side plate; and
the other end side-blocking plate that blocks an opening of the other end side opposite to the one end side,
wherein a bending piece is provided at an end part of the other end side of the tubular side plate, and is pressed while being surrounded by a breakable line and a bending line so as to be broken and bent to an inside of the box along the breakable line,
wherein, in the bending state, the bending piece is configured such that a distal end part of the bending piece is positioned at the other end side from a receiving area of the object to be packaged and inhibits movement of the object to be packaged to the other end side,
wherein a bubble-containing buffer material is filled in a part corresponding to the bending piece at a side of the other end side-blocking plate of the packaging box, and
wherein a toner cartridge, which includes a driving connection part at one side end part in a longitudinal direction of a hollow cylindrical case storing printing toner and a handle part at the other side end part in the longitudinal direction of the case, is received in the packaging box such that the driving connection part faces the bubble-containing buffer material and the handle part faces the one end side-blocking plate.

2. The packaging form of claim 1 ,
wherein the bending piece is configured to allow the buffer material to be visible from an opening formed when the bending piece is bent.

3. The packaging form of claim 1 , wherein the one end side-blocking plate is provided with a belt-like part interposed between a pair of breakable lines for opening.
