Abstract
A stabilized carton having four sides, a bottom and a top with improved structural stability is formed by cutting a notch in one of the lower major flaps and imprinting an embossment into a lower minor flap. The first and second lower minor flaps and the first and second lower major flaps are then folded, forming the bottom of the carton. The embossment is fitted into the notch, providing enhanced stability to the carton. Cut sections formed on a fold line of the flaps and a lower major flap that extends across the bottom of the carton also stabilize the carton.

A carton comprising:
- a front panel with a first lower major flap;
- a rear panel with a second lower major flap;
- a first side panel with a first lower minor flap;
- a second side panel with a second lower minor flap;
- and
- a bottom formed from the first and second lower minor flaps and first and second lower major flaps, wherein one of the first and second lower major flaps is formed with a notch having a shape, and one of the first and second lower minor flaps is formed with an embossment that has a shape that fits into the shape of the notch, the embossment is formed as a recess on a first side of the first lower minor flap and a protrusion on a second side of the first lower minor flap, and the protrusion extends from the first lower minor flap a distance equal to a thickness of the first major flap.
A carton comprising:
- a front panel with a first lower major flap;
- a rear panel with a second lower major flap;
- a first side panel with a first lower minor flap;
- a second side panel with a second lower minor flap;
- and
- a bottom formed from the first and second lower minor flaps and first and second lower major flaps, wherein one of the first and second lower major flaps is formed with a notch having a shape, and one of the first and second lower minor flaps is formed with an embossment that has a shape that fits into the shape of the notch, the embossment is formed as a recess on a first side of the first lower minor flap and a protrusion on a second side of the first lower minor flap, wherein the rear panel and the second lower major flap are connected along a fold line and the fold line is formed with cut sections.
A method of forming a stabilized carton having a front panel with a first lower major flap, a rear panel with a second lower major flap, a first side panel with a first lower minor flap, a second side panel with a second lower minor flap;
- and a bottom, said method comprising:
- cutting a notch having a shape in one of the first and second lower flaps;
- imprinting an embossment into another of the first and second lower flaps, wherein imprinting the embossment includes pressing the first lower minor flap to form a recess on a first side of the first lower minor flap and a protrusion on a second side of the first lower minor flap;
- and
- folding first and second lower minor flaps and first and second lower major flaps;
- while fitting the embossment into the notch so that the protrusion extends from the first lower minor flap a distance equal to a thickness of the first major flap.
