Snap lock bottom box dieline

About this dieline

A snap lock bottom box, also called a 1-2-3 bottom or lock bottom box, closes its bottom with four flaps that fold in one after another and lock, with no glue or tape. It is one sheet of board, glued once down the side, and ships flat. In FEFCO terms it is the 0215 family: the same bottom with a tuck lid (0215), four flaps (0216), a carry handle (0217), the same lock on top (0220), an open top (0221) or a tuck lid with a hang tab for a shop peg (0240).

Enter the length, width and height, pick the top and the board, paperboard or corrugated up to 7 mm, and download a print-ready PDF with cut and crease lines. The tongue, the notch and the side flaps are sized from the box, so any size locks.

Common sizes, length × width × height: about 46 × 46 × 152 mm for a slim carton, 89 × 89 × 102 mm (3½ × 3½ × 4 in) for a candle or a jar, 120 × 60 × 160 mm for cosmetics and 600 × 400 × 400 mm for a corrugated shipper.

How do I close the bottom?

Fold the two side flaps in first, then the back flap with the notch, then the front flap last, pushing its tongue into the notch and under the side flaps. It locks flat; push it from inside to open it again.

What is the difference from a crash lock bottom?

A crash lock bottom is glued at the factory and pops into shape when you open the box. A snap lock bottom has no glue: you fold it by hand, which takes a few seconds but costs less to make and works on corrugated board too.
