Folding Carton
Tuck End Snap Lock Bottom
This carton has a standard tuck closure on top and a snap lock (also called 1-2-3 bottom) on the base. The bottom is formed by folding interlocking flaps in sequence: the large panel folds first, the dust flaps fold next, and the final panel snaps into a slot to lock everything in place. No glue or tape is needed, but the base is significantly stronger than a simple tuck end.
It's a good fit for heavier items like bottled beverages, large candles, or boxed electronics where a standard tuck bottom might sag or pop open.
