Packaging box

Abstract

A packaging box is provided with an exterior unit, and a packaging component set in the exterior unit. The packaging component includes an article mounting plane unit on which to mount an article, a pair of suspending units that are made by bending upward the article mounting plane unit at right and left ends of the article mounting plane unit so as to suspend the article mounting plane unit, and a pair of side plane units that are made by bending downward the pair of suspending units at upper ends of the pair of the suspending units, in which the pair of side plane units are kept in surface contact with two opposing walls of the exterior unit.

1 . A packaging box comprising:

         2 . The packaging box according to  claim 1 , wherein:
 the packaging component includes a pair of downward-bent units that are made by bending, obliquely downward, the article mounting plane unit at front and back ends of the article mounting plane unit in such a manner that the downward-bent units get closer to each other as a distance on the downward-bent units from the front and back ends of the article mounting plane unit increases.   
     
     
         3 . The packaging box according to  claim 2 , further comprising:
 a supporting unit that is set on a bottom plane unit of the exterior unit and that is in surface contact with outer surfaces of the pair of downward-bent units so as to support the pair of downward-bent units.   
     
     
         4 . The packaging box according to  claim 3 , wherein:
 the supporting unit includes a pair of center-side oblique plane units, and a pair of outer side oblique plane units:   the pair of center-side oblique plane units are angled so as to form a “V” shape, and are in surface contact with outer surfaces of the pair of downward-bent units; and   the pair of outer side oblique plane units are made by bending, obliquely downward, the pair of center-side oblique plane units at upper ends of the pair of center-side oblique plane units in such a manner that the pair of outer side oblique plane units get further from each other as a distance on the outer side oblique plane units from the upper ends increases.   
     
     
         5 . The packaging box according to  claim 1 , wherein:
 the article mounting plane unit is positioned with interspaces between the exterior unit and front and back sides of the article mounting plane unit.   
     
     
         6 . The packaging box according to  claim 5 , further comprising:
 a small storage box that is set in an interspace between the exterior unit and a front or back side of the article mounting plane unit in order to store an item other than the article.   
     
     
         7 . The packaging box according to  claim 2 , wherein:
 the pair of side plane units include reinforcement units to support the pair of downward-bent units.   
     
     
         8 . The packaging box according to  claim 7 , wherein:
 the reinforcement units are formed by bending the pair of side plane units at lower portions of front and back ends of the pair of side plane units.   
     
     
         9 . The packaging box according to  claim 8 , wherein:
 the reinforcement unit is a triangle composed of a side formed by a lower portion of the front or back end of the pair of side plane units, a side formed of a portion bordering on a bottom plane unit of the exterior unit, and a side formed by a portion bordering on the pair of downward-bent units.   
     
     
         10 . The packaging box according to  claim 7 , wherein:
 the pair of downward-bent units include notches that are engaged with the reinforcement units.   
     
     
         11 . The packaging box according to  claim 7 , wherein:
 the reinforcement units include notches that are engaged with the pair of downward-bent units.   
     
     
         12 . The packaging box according to  claim 1 , wherein:
 the article mounting plane unit includes falling off prevention convex portions to prevent an article from falling off; and   the falling off prevention convex portions are formed by making a cut on the article mounting plane unit.   
     
     
         13 . The packaging box according to  claim 1 , wherein:
 the pair of side plane units include engagement units that are engaged with the pair of suspending units; and   the engagement units are formed by making a cut on the pair of side plane units.   
     
     
         14 . The packaging box according to  claim 13 , wherein:
 a partition unit to partition a space above the article mounting plane unit into upper and lower spaces is set on the engagement units.   
     
     
         15 . The packaging box according to  claim 2 , wherein:
 the pair of downward-bent units include belt insertion slots into which belt units are inserted to hold the article on the article mounting plane unit.   
     
     
         16 . The packaging box according to  claim 1 , wherein:
 the two opposing walls of the exterior unit include insertion slots into which the pair of side plane units are inserted from above; and   the pair of side plane units are inserted into the insertion slots so as to be in surface contact with the walls.   
     
     
         17 . The packaging box according to  claim 2 , wherein:
