Packaging box

Abstract

A packaging box includes an exterior unit and a packaging component that is set in the exterior unit. The packaging component includes an article mounting plane unit that mounts an article on, and a pair of downward-bent units that is bent downward from the front end and the rear end of the article mounting plane unit with respect to the side on which the article is mounted. A film for covering and holding the article is adhered to the pair of downward-bent units. The pair of downward-bent units include an outward-bent unit that is provided outside the downward-bent units, and that is bent with respect to the downward-bent units.

1 . A packaging box, comprising:
 an exterior unit; and   a packaging component that is set in the exterior unit, wherein:   the packaging component comprises: an article mounting plane unit that mounts an article on; and a pair of downward-bent units that is bent downward from a front end and a rear end of the article mounting plane unit with respect to a side on which the article is mounted;   a film for covering and holding the article is adhered to the pair of downward-bent units; and   the pair of downward-bent units comprise an outward-bent unit that is provided outside the downward-bent units, and that is bent with respect to the downward-bent units.   
     
     
         2 . The packaging box according to  claim 1 , wherein
 the packaging component comprises: a pair of suspending units that is bent upward from a left end and a right end of the article mounting plane unit; and a pair of side plane units that is bend downward from an upper end of the pair of suspending units.   
     
     
         3 . The packaging box according to  claim 2 , wherein
 the pair of side plane units is kept in surface-contact with two opposite walls of the exterior unit.   
     
     
         4 . The packaging box according to  claim 1 , wherein
 the pair of downward-bent units further comprises an inward-bent unit that is bent from the outward-bent unit in a direction opposite to the outward-bent unit.   
     
     
         5 . The packaging box according to  claim 1 , wherein
 a plurality of folds of the outward-bent unit are formed for the pair of downward-bent unit.   
     
     
         6 . The packaging box according to  claim 5 , wherein
 the folds are parallel to one another.   
     
     
         7 . The packaging box according to  claim 1 , further comprising
 an angle regulative bending piece that regulates a bending angle of the pair of downward-bent units.   
     
     
         8 . The packaging box according to  claim 7 , wherein
 the angle regulative bending piece is bent from the downward-bent unit toward the article mounting plane unit.   
     
     
         9 . The packaging box according to  claim 1 , wherein
 the downward-bent unit is bent diagonally downward from the front end and the rear end of the article mounting plane unit in a direction of approaching each other.   
     
     
         10 . The packaging box according to  claim 1 , further comprising
 a holding component that is arranged at an upper part of the article, wherein   the holding component comprises a plane unit that parallel to the article mounting plane unit and a convex unit that is notched in the plane unit and that is bent downward.
