Collapsible box cover

Abstract

A box cover includes a cover panel, a pair of first side panels, and a pair of second side panels. After assembly, the box cover is collapsable.

1 . A box cover comprising:
 a cover panel having four vertices;   a pair of first side panels, connecting with a first pair of opposite sides of the cover panel, having a diagonal fold line extending from each of the vertices to an outer edges of the pair of first side panels; and   a pair of second side panels connecting with a second pair of opposite sides of the cover panel;   wherein the pair of first side panels and the pair of second side panels are perpendicular to the cover panel when the box cover is in an assembled state; the pair of second side panels and corners beyond the diagonal fold lines of the pair of first side panels are capable of being folded to abut an inner side of the cover panel; main portions between the diagonal fold lines of the pair of first side panels are capable of being unfolded and located in substantially a same plane as the cover panel.   
     
     
         2 . The box cover of  claim 1 , wherein a glue panel connects with an end of each first side panel, and a cut is defined between the glue panel and one corresponding end of the pair of the second side panels. 
     
     
         3 . The box cover of  claim 2 , wherein a width of each of the pair of first side panels is substantially equal to the width of the pair of second side panels, and the glue panels is square-shaped. 
     
     
         4 . The box cover of  claim 3 , wherein each of the corners has a triangular shape, each of the main portions has a trapezoidal shape. 
     
     
         5 . The box cover of  claim 1 , wherein each of the pair of first side panels is connected with the cover panel by a first fold lines, an angle between the first score and each of the diagonal fold lines is substantially 45 degrees. 
     
     
         6 . A box cover comprising:
 a cover panel having four vertices;   a pair of first side panels, connecting with a first pair of opposite sides of the cover panel by a pair of first fold lines, having four diagonal fold lines that respectively extends from the four vertices to outer edges thereof; and   a second pair of second side panels connecting with a second pair of opposite sides of the cover panel by a pair of second fold lines;   wherein the pair of first side panels and the pair of second side panels are perpendicular to the cover panel when the box cover is at a use state; the pair of second side panels and corners beyond the diagonal fold lines of the pair of first side panels are capable of being folded along the pair of second fold lines and the diagonal fold lines to abut an inner side of the cover panel; main portions between the diagonal fold lines of the pair of first side panels are capable of being unfolded and locating at a same plane as the cover panel.   
     
     
         7 . The box cover of  claim 6 , wherein four glue panels are connecting with opposites ends of the pair of the first side panels, and a cut is defined between each of the glue panels and one corresponding end of the pair of the second side panels. 
     
     
         8 . The box cover of  claim 7 , wherein a width of each of the pair of first side panels is substantially equal to the width of the pair of second side panels, and each of the glue panels is square-shaped. 
     
     
         9 . The box cover of  claim 8 , wherein each of the corners has a triangular shape, and each of the main portions has a trapezoidal shape. 
     
     
         10 . The box cover of  claim 6 , wherein an angle between the first score and each of diagonal fold lines is 45 degrees.
