Foldable Structure

Abstract

A single blank of sheet material is configured to be formed into a foldable structure having a bottom panel which defines a container region. The carton includes an end wall assembly having triangular panels configuring the end wall assembly to define a triangular opening.

1 . A carton formed from a single blank of sheet material, the carton comprising:
 a bottom wall defining opposing first and second side ends and opposing top and bottom ends;   a first sidewall foldably connected to said first side end of said bottom wall;   a second sidewall foldably connected to said second side end of said bottom wall;   a bottom end wall assembly foldably connected to said bottom end of said bottom wall, said bottom end wall assembly including:
 a first bottom end panel bordered by a first fold line and opposing second and third fold lines; 
 a second bottom end panel foldably connected to said first bottom end panel along the first fold line, said second bottom end panel also bordered by a fourth fold line opposite said first fold line; 
 a third bottom end panel foldably connected to said second bottom end panel along the fourth fold line; 
 a first triangular bottom panel foldably connected to said first bottom end panel along said second fold line; and 
 a second triangular bottom panel foldably connected to said first bottom end panel along said third fold line. 
   
     
     
         2 . The foldable structure of  claim 1 , wherein the first triangular bottom panel is also bordered by fifth and sixth fold lines and the second triangular bottom panel is bordered by seventh and eighth fold lines with said first sidewall foldably connected to said first bottom triangular panel along said fifth fold line and said second sidewall foldably connected to said second triangular bottom panel along said seventh fold line, said bottom end wall assembly further including:
 a first bottom flap panel foldably connected to said first triangular bottom panel along said sixth fold line; and   a second bottom flap panel foldably connected to said second triangular bottom panel along said eight fold line.   
     
     
         3 . The foldable structure of  claim 2  further including a top end wall assembly foldably connected to said top end of said bottom wall. 
     
     
         4 . The foldable structure of  claim 3  wherein said top end wall assembly includes:
 a first top end panel bordered by a ninth fold line and opposing tenth and eleventh fold lines;   a second top end panel foldably connected to the first top end panel along the ninth fold line, said second top end panel also bordered by a twelfth fold line opposite said ninth fold line;   a third top end panel foldably connected to said second top end panel along said twelfth fold line;   a first triangular top panel foldably connected to said first top end panel along said tenth fold line; and   a second triangular top panel foldably connected to said first top end panel along said eleventh fold line.   
     
     
         5 . The foldable structure of  claim 4 , wherein the first triangular top panel is also bordered by thirteenth and fourteenth fold lines and the second triangular top panel is bordered by fifteenth and sixteenth fold lines with said first sidewall foldably connected to said first top triangular panel along said thirteenth fold line and said second sidewall is foldably connected to said second triangular top panel along said fifteenth fold line, said top end wall assembly further including:
 a first top flap panel foldably connected to said first triangular top panel along said fourteenth fold line; and   a second top flap panel foldably connected to said second triangular top panel along said sixteenth fold line.   
     
     
         6 . The foldable structure of  claim 1  wherein said first and second sidewall are configured as rectangles. 
     
     
         7 . The foldable structure of  claim 1  wherein said first, second and third bottom panels of said bottom end wall assembly are configured as rectangles. 
     
     
         8 . The foldable structure of  claim 1  wherein said first and second triangular bottom panels of said bottom wall assembly are configured as equilateral triangles. 
     
     
         9 . The foldable structure of  claim 5  wherein said first, second and third bottom panels of said top end wall assembly are configured as rectangles. 
     
     
         10 . The foldable structure of  claim 5  wherein said first and second triangular top panels of said top end wall assembly are configured as equilateral triangles.
