Title: Packing box

Description:
CROSS REFERENCE TO RELATED APPLICATION  
      This application claims the benefit under 35 USC § 119 of Chinese Patent Application having Serial No. 200510110080.7 filed on Nov. 7, 2005, which is incorporated by reference herein.  
     BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      Embodiments of the present invention generally relate to a packing box. More particularly, embodiments of the present invention relate to reinforced paperboard layers of a packing box that can be used to pack, store, and transport bulk materials.  
      2. Description of the Related Art  
      Boxes used for packing, storing, and transporting bulk material are typically made of hard single layer paperboard. Problems with these conventional packing boxes are that the packed material is relatively heavy and the bottom of the packing box may break open.  
      There is a need therefore for a packing box that is reliable and can be used to pack, store, and transport bulk materials.  
     SUMMARY OF THE INVENTION  
      In one or more embodiments, a packing box is provided. The packing box provides reinforced strength and a bottom that will not fail upon packing, storage, and transport of heavy bulk materials.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
      A detailed description will now be provided. Each of the appended claims defines a separate invention, which for infringement purposes is recognized as including equivalents to the various elements or limitations specified in the claims. Depending on the context, all references below to the “invention” may in some cases refer to certain specific embodiments only. In other cases it will be recognized that references to the “invention” will refer to subject matter recited in one or more, but not necessarily all, of the claims. Each of the inventions will now be described in greater detail below, including specific embodiments, versions and examples, but the inventions are not limited to these embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the inventions, when the information in this patent is combined with available information and technology.  
      In one or more embodiments, a packing box is provided. One paperboard is folded to form the packing box. Four sides and the top cover of the folded packing box can include two paperboard layers. The bottom of the folded packing box can include four paperboard layers. Accordingly, the folded packing box provides reinforced strength and a bottom that will not fail upon packing, storage, and transport of heavy bulk materials.

Referring to  FIGS. 1, 2 , and  3 , the packing box can be formed from a single paperboard. The single paperboard  100  (identified in  FIG. 3 ) can include portions for: outer sides  1 ,  2 ,  3 ,  4 , and  5 ; interior sides  6  and  7 ; interior bottoms  8 ,  9 ,  10 , and  12 ; an interior top  11 ; an outer bottom  13 ; an outer top  14 , air vents  30 ,  31 , and  33 ; narrow slots  35 ,  36 ,  37 ,  38 ,  39 ,  40 ,  41 , and  42 ; and plugs  26 ,  34 ,  50 ,  51 ,  52 ,  53 ,  54 , and  55 . As described in more detail below, the paper board  100  can be folded along one or more of these portions to provide an assembled box  105  (depicted in  FIG. 1 ).  
      Referring to  FIG. 3 , narrow slots  35 ,  36 ,  37 ,  38 ,  39 ,  40 ,  41 , and  42  can be disposed or formed on the outer side paperboards  1 ,  2 ,  3 ,  4 , and  5 , interior bottom paperboards  8  and  9 , and/or air vent  31 , respectively. Plugs  26 ,  34 ,  50 ,  51 ,  52 ,  53 ,  54 , and  55  can be formed on the outer side  5 , interior side  6 , interior bottoms  10  and  12 , interior top  11 , outer bottom  13 , and outer top  14 , respectively.  
      The outer side  5 , air vents  31 ,  33 , and plug  34  can be arranged perpendicular to outer top  14  and set inside outer sides  2 ,  3 . Plug  26  can be connected through narrow slot  38  and plug  50  can be connected through narrow slot  41 . Interior bottoms  8 ,  9 ,  10 , and  12  can be perpendicular to outer sides  1  and  3  and set inside outer bottom  13 . Interior side  6  can be perpendicular to outer bottom  13  and set inside outer side  3 . Plug  51  can be connected through narrow slots  39  and  40 . Interior side  7  can be perpendicular to interior bottom  10  and can be set inside outer side  1 . Interior top  11  can be perpendicular to interior side  7  and can be set inside outer top  14 . Plug  55  can be connected through narrow slot  42 .  
      In assembly, the packing box  105  can be formed by folding the aforementioned portions of the paperboard  100 . In one or more embodiments, the outer side  2  can be folded to be perpendicular to outer side  1 . Outer side  5  can be folded to be perpendicular to outer side  4 . Outer side  4  can be folded to be perpendicular to outer side  3 . Outer side  3  can be folded to be perpendicular to outer side  1 . When outer side  5  is overlaid on outer side  2  on the inside, plug  26  can connect to narrow slot  38 , and plug  50  can connect to narrow slot  71 . Accordingly, outer bottom  13  can be folded to be perpendicular to outer side  4  and plug  54  can connect to narrow slot  37 . Interior bottom  12  can be folded to be perpendicular to outer side  3  and outer side  1  and can be overlaid on outer bottom  13  on the inside. Interior bottom  9  can be folded to be perpendicular to outer side  1  and can be overlaid on interior bottom  12  on the outside. Interior bottom  8  can be folded to be perpendicular to outer side  2  and outer side  1  and can be overlaid on interior bottom  12  on the inside. Interior side  6  can be folded to be perpendicular to interior bottom  8  and outer side  1  and can be overlaid on interior bottom  12  on the inside. Outer side  6  can be folded to be perpendicular to interior bottom  8  and outer side  1  and can be overlaid on outer side  3  on the inside. Plug  51  can connect to narrow slots  39  and  44 . Interior bottom  10  can be folded to be perpendicular to outer side  4  and can be overlaid on interior bottom  8  on the outside. Plug  52  can connect to narrow slots  35  and  36 . Interior side  7  can be folded to be perpendicular to interior bottom  10  and can be overlaid on outer side  1  on the inside. Air vent  31  can be folded to be perpendicular to outer top  14 . Outer top  14  can be folded to be perpendicular to outer side  1 . Plug  34  can be folded to be perpendicular to outer top  14  and can be overlaid on outer side  4  on the inside. Interior top  11  can be folded to be perpendicular to interior side  7  and can be overlaid on outer top  14  on the inside. Plug  55  can connect to narrow slot  42 .  
      As used herein, the term “perpendicular” refers to the relative orientation between two or more portions of the packing box  105 , and is not limited to a 90° angle therebetween so long as the two or more portions can be arranged and interlocked to form a box. Accordingly, “perpendicular” includes a substantially perpendicular arrangement or orientation and includes any angle between 60° to 120°, preferably 70° to 110°, more preferably 80° to 100°, and more preferably 85° to 95°.
