Packaging box

Abstract

A packaging box includes a foldable outer panel having a substantially rectangular wall-forming section with two opposite first bounding ends, two opposite second bounding ends extending between and interconnecting the first bounding ends, and a plurality or spaced-apart first folding lines that extend substantially parallel to and between the first bounding ends and that divide the wall-forming section into a plurality of surrounding walls. An object-retaining section is connected foldably to and extends away from one of the first bounding ends in a direction parallel to the second bounding ends, and has at least one retaining hole. A foldable inner panel is connected to one of the surrounding walls, and has two opposite end walls foldably disposed on the one of the surrounding walls.

What is claimed is: 
     
         1 . A packaging box having a folded configuration and a spread configuration, said packaging box comprising:
 a foldable outer panel including a substantially rectangular wall-forming section and an object-retaining section, said wall-forming section having two opposite first bounding ends, two opposite second bounding ends extending between and interconnecting said first bounding ends, and a plurality of spaced-apart first folding lines that extend substantially parallel to and between said first bounding ends and that divide said wall-forming section into a plurality of surrounding walls, said object-retaining section being connected foldably to one of said first bounding ends and extending away from said, one of said first bounding ends in a direction parallel to said second bounding ends, said object-retaining section having at least one retaining hole; and   a foldable inner panel connected to one of said surrounding walls formed between said first folding lines, and having two opposite end walls foldably disposed on said one of said surrounding walls;   wherein, when said packaging box is placed in the spread configuration, said end walls are able to lay fiat on said one of said surrounding walls and to respectively and outwardly project from said second bounding ends in opposite directions; and when said packaging box is placed in the folded configuration, said end walls upstand from said one of said surrounding walls, said wall-forming section is folded along said first folding lines to stir round said end walls and to cooperate with said end walls to form a receiving space, and said object-retaining section is folded along said one of said first bounding ends and is disposed across said receiving space and between said end walls, said at least one retaining hole being adapted to receive and retain an object in said receiving space.   
     
     
         2 . The packaging box as claimed in  claim 1 , wherein said at least one retaining hole includes a plurality of said retaining holes for respectively receiving a plurality of objects in a spaced apart fashion when said packaging box is placed in the folded configuration. 
     
     
         3 . The packaging box as claimed in  claim 1 , wherein each of said foldable outer and inner panels is a single-piece paper board, said foldable inner panel further having a base part that is connected foldably between said end walls and that is superimposed fixedly on said one of said surrounding walls. 
     
     
         4 . The packaging box as claimed in  claim 1 , wherein said foldable inner panel further has a plurality of second folding lines each of which is disposed between one of said end walls and said base part, said second folding lines being disposed parallel to and between said second bounding ends and being spaced apart from said second bounding ends, said end walls upstanding from said one of said surrounding walls inwardly of said second bounding ends when said packaging box is placed in the folded configuration. 
     
     
         5 . The packaging box as claimed in  claim 4 , wherein said object-retaining section has a connecting part connected foldably to said one of said first bounding ends, and an extension part that projects from one side of said connecting part opposite to said one of said first bounding ends, said extension part having two opposite sides that are parallel to said second bounding ends, that are indented respectively from said connecting part along directions parallel to said first bounding ends and that are substantially and respectively aligned with said second folding lines, said connecting part having two first notches that respectively adjoin said two opposite sides of said extension part and that extend in a direction parallel to said second bounding ends, each of said end walls having a second notch, said second notches of said end walls respectively interlocking with said first notches when said foldable outer and inner panels are folded, whereby said object-retaining section engages said second notches, said-end walls respectively engage said first notches, and said object-retaining section is fixed to said end walls. 
     
     
         6 . The packaging box as claimed in  claim 5 , wherein said foldable outer panel further includes a flange part that is connected foldably to and projects from the other one of said first bounding ends of said wall-forming section in a direction parallel to said second bounding ends when said packaging box is placed in the spread configuration, said flange part having two third notches extending in a direction parallel to said second bounding ends and respectively aligned with said first notches, and wherein, when said packaging box is placed in the folded configuration, said flange part is folded along said other one of said first bounding ends and is stacked on said object-retaining section, said third notches are respectively disposed on said first notches and interlocked with said second notches to enable said flange part and said object-retaining section to commonly engage said second notches, and said two opposite first bounding ends of said wall-forming section adjoin each other. 
     
     
         7 . The packaging box as claimed in  claim 6 , wherein each of said end walls has a notch edge formed in said second notch, and a notch open end opposite to said notch edge, said notch edge being stepped to form a deep edge portion and a shallow edge portion, said deep edge portion being able to engage said object-retaining section, said shallow edge portion being able to engage said flange part, a depth of said deep edge portion from said notch open end being larger than a depth of said shallow edge portion from said notch open end.
