Abstract

A rectangular prismatic carton and method for bulk packing pistons or other similar products are provided, which improve the fill efficiency of the product without increasing the risk of damaging a percentage of the packaged product. The carton comprises a carton having length l, width w, and height h, such that h is greater than l and w, the top and a bottom being formed by overlapping flaps. The carton has a ratio of the opening perimeter of the carton to the height of the carton is less than about 2. The carton provides a reduced opening cross-section that allows for improved fill efficiency when filling the carton with pistons or other product and leaving a volume of unfilled space remaining within the carton.

Claims

exact text as granted — not AI-modified
1 . A method of bulk packing pistons in rectangular prismatic cartons, the method comprising dropping the pistons into the rectangular prismatic carton though an opening in one of the two smallest faces of the rectangular prismatic carton. 
   
   
       2 . A method of bulk packing pistons in rectangular prismatic cartons, the method comprising: providing a rectangular prismatic carton having length l, width w, and height h, such that h is greater than l and w, the top and a bottom formed by overlapping flaps; dropping the pistons into the carton through the open top; and, closing the carton by overlapping the flaps. 
   
   
       3 . The method of bulk packing pistons according to  claim 2  wherein the height h of the carton is less than 36 times the height H of the pistons. 
   
   
       4 . The method of bulk packing pistons according to  claim 2  wherein the height h of the carton is less than 36 times the diameter D of the pistons. 
   
   
       5 . The method of bulk packing pistons according to  claim 2  wherein the length l of the carton is less than 24 times the height H of the pistons. 
   
   
       6 . The method of bulk packing pistons according to  claim 2  wherein the width w of the carton is less than 15 times the height H of the pistons. 
   
   
       7 . The method of bulk packing pistons according to  claim 2  wherein the length l of the carton is less than 24 times the diameter D of the pistons. 
   
   
       8 . The method of bulk packing pistons according to  claim 2  wherein the width w of the carton is less than 15 times the diameter D of the pistons. 
   
   
       9 . The method of bulk packing pistons according to  claim 2  wherein the product of the length l and the width w is less than 240 times the transverse cross sectional area of the pistons (πD 2 /4). 
   
   
       10 . The method of bulk packing pistons according to  claim 2  wherein the product of the length l and the width w is less than 55 times the longitudinal cross sectional area of the pistons (H×D). 
   
   
       11 . A rectangular prismatic carton of bulk-packed pistons, the rectangular prismatic carton having length l, width w, and height h, such that h is greater than l and w, the top and a bottom being formed by overlapping flaps. 
   
   
       12 . The rectangular prismatic carton of  claim 11 , wherein the carton is configured to have a ratio of opening perimeter length to carton height of less than about 2.75, for providing improved fill efficiency when filling the carton with bulk-packed pistons and leaving a volume of unfilled space remaining at the top of the carton. 
   
   
       13 . The rectangular prismatic carton according to  claim 11  wherein the height h of the carton is less than 36 times the height H of the pistons. 
   
   
       14 . The rectangular prismatic carton according to  claim 11  wherein the height h of the carton is less than 36 times the diameter D of the pistons. 
   
   
       15 . The rectangular prismatic carton according to  claim 11  wherein the length l of the carton is less than 24 times the height H of the pistons. 
   
   
       16 . The rectangular prismatic carton according to  claim 11  wherein the width w of the carton is less than 15 times the height H of the pistons. 
   
   
       17 . The rectangular prismatic carton according to  claim 11  wherein the length l of the carton is less than 24 times the diameter D of the pistons. 
   
   
       18 . The rectangular prismatic carton according to  claim 11  wherein the product of the length l and the width w is less than 240 times the transverse cross sectional area of the pistons (πD 2 /4). 
   
   
       19 . The rectangular prismatic carton according to  claim 11  wherein the product of the length l and the width w is less than 55 times the longitudinal cross sectional area of the pistons (H×D). 
   
   
       20 . A method of bulk packing pistons in rectangular prismatic cartons, the method comprises providing a rectangular prismatic carton having a height h that is greater than both the length l and width w of an open end in the carton, and filling the carton with randomly oriented pistons to within a predetermined distance from the plane of the opening in the carton to provide a volume of unfilled space remaining within the interior of the carton.
