Description

The present invention relates to an apparatus for packaging an article having a recess on the surface of a main body.

When a device is stored, transported, handled, or stored in a packaging box, a portion that is vulnerable to the impact of the device may be deformed or damaged due to the impact from the outside. In order to avoid this, the device is protected by arranging a cushioning material along the shape of such a portion.

For example, since the concave partition wall of a device having a concave portion on the surface of the main body is thin, the portion is vulnerable to impact and may be deformed or damaged by external impact. An example of a device having such a shape is a hand dryer shown in FIG. When this equipment is transported, an external force is prevented from being directly applied to the surface having the recess by, for example, sandwiching a cushioning material between the equipment and the packaging box.

Various methods have been studied for packing equipment having irregularities on the surface of the main body using a cushioning material. For example, in Patent Document 2, inner flaps having through holes are provided on the upper and lower sides of a packaging box, cushioning materials provided with convex portions are arranged on the upper and lower sides of the device, and the convex portions of the cushioning materials are arranged. A method is disclosed in which a device is fixed in a packaging box by being fitted into the through hole of the inner flap.
