Square & Rectangle Container Assembly
Our boxes will arrive at the destination of your choice folded flat.
Step 1
Expand the box and refold it so the open/cut corners of the top sides are opposite each other, then crease and fold down the top collar of the box.
Step 2
Open the carton fully, place upside down, and fold down the large #1 flap on the bottom.
Step 3
Fold down the #2 flap.
Step 4
Insert the #3 flap into the nearest cutout on the #2 flap. (On the 3-gallon container, the #3 flap folds across the #2 flap.)
Step 5
Insert the #4 flap into the remaining cutout on the #2 flap.
Step 6
Turn right side up and check inside the box to be sure flaps #2 and #3 are lying flat and that #1 flap is forming a good seal on the bottom of the container.

Square & Rectangle Lid Assembly
The lids will come shipped flat. Gently crease all scores on the lid.
Step 1
Fold the short panels up, then fold the scored ends in to form the corners.
Step 2
Fold the long panels up and fold again to tuck the tabs on the end panels into the small notches in the top of the lid.
