BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to box covers, and more particularly to a box cover which facilitates storage and transportation. 
         [0003]    2. Description of Related Art 
         [0004]    Referring to  FIGS. 4 and 5 , a typical box cover may include a cover panel  102 , a pair of first side panels  104  extending from a first pair of opposite edges of the cover panel  102 , and a pair of second side panels  106  extending from a second pair of opposite edges of the cover panel  102 . A pair of glue panels  108  is located at opposite ends of each of the first side panels  104 . After the box cover is folded from an unassembled state (see  FIG. 4 ) to an assembled state (see  FIG. 5 ), the first side panels  104  and the second side panels  106  are folded to be perpendicular to the cover panel  102 . The glue panels  108  are folded and adhered to the interior surfaces the second side panels  106 . However, the assembled box cover, which is thicker than an unassembled box cover, takes up considerable storage space, which does not facilitate economical storage and transportation. 
         [0005]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0011]    The disclosure is illustrated by way of example and not by way of limitation. In the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
         [0012]    Referring to  FIG. 1 , an exemplary embodiment of a box cover  10  comprises an integral panel (such as a sheet of paperboard) which is divided into several parts: a cover panel  12 , a pair of first side panels  14 , a pair of second side panels  16 , and four glue panels  145  located at four corners of the cover panel  12 . The cover panel  12  has a rectangle shape with four vertices. Each of the first side panels  14  is connected with the cover panel  12  by a first score  11 . Each of the second side panels  16  is connected with the cover panel  12  by a second score  13 . Each of the glue panels  145  has a square shape and connects with the first side panels  14  by a third score  143 . Each of the first side panels  14  has a pair of diagonal perforated fold lines  141  at opposite corners thereof. Each of the diagonal perforated fold lines  141  extends from one of the vertices of the cover panel  12  to an outer edge of the corresponding first side panel  14 . An angle between the first score  11  and each of the diagonal perforated fold lines  141  may be 45 degrees. A cut  147  is defined between the glue panel  145  and the second side panel  16  at each of the four corners of the cover panel  12 . In an exemplary embodiment, a width of each of the first side panels  14  is substantially equal to the width of the second side panels  16 . 
         [0013]    Referring to  FIG. 2 , to fold the box cover  10  into an assembled state, the first side panels  14  and the second side panels  16  are folded along the first scores  11  and the second scores  13  to form a certain angle (typically 90 degrees). The glue panels  145  are folded and affixed to inner surfaces of the second side panels  16 . 
         [0014]    Referring to  FIG. 3 , to fold the assembled box cover  10  into a collapsed state, triangular corners  14   a  of the first side panels  14  and the second side panels  16  are folded inwardly along the diagonal perforated fold lines  141  and the second scores  13  until abutting on an inner side of the cover panel  12 . Simultaneously, a trapezoidal-shaped main portion  14   b  of each of the first side panels  14  is folded out into a collapsed position onto the cover panel  12 . In the collapsed state, the box cover  10  takes up less storage space than that of a box cover  10  being shipped assembled and not collapsed, which improves storage and increases transportation yield. 
         [0015]    While the present disclosure has been illustrated by the description of preferred embodiments thereof, and while the preferred embodiments have been described in considerable detail, it is not intended to restrict or in any way limit the scope of the appended claims to such details. Additional advantages and modifications within the spirit and scope of the present disclosure will readily appear to those skilled in the art. Therefore, the present disclosure is not limited to the specific details and illustrative examples shown and described.
