Abstract
One or more rods pass through the corrugations of first and second folded down flaps and across the divide between adjacent edges of the flaps of a cardboard box blank to hold the flaps together and in a closed position.

A cardboard box construction, comprising:
- a cardboard carton blank having opposing first and second panels, opposing third and fourth panels, opposing first and second flaps, opposing third and fourth flaps, a first fold line between the first panel and the first flap, a second fold line between the second panel and the second flap, a third fold line between the third panel and the third flap, and a fourth fold line between the fourth panel and the fourth flap;
- a rod;
- a hole passing through an outwardly-disposed surface of the first flap and/or the first panel and at the first fold line and providing access from a box exterior to corrugations of the first flap;
- the cardboard carton blank and the rod being configured such that the rod can be positioned in an operative position extending between the first and second flaps, and within corrugations of both of the first and second flaps and holding the first and second flaps in folded-down closed positions with distal edges of the first and second flaps adjacent one another, the third and fourth flaps folded inside of the first and second flaps and the rod extending across a divide between the adjacent distal edges;
- and
- the rod being configured to be positioned into the operative position by inserting an end thereof from the box exterior into the hole and thereby into the corrugations of the first flap and pushing the end through the first flap, across the divide and into corrugations of the second flap and to the operative position.

- and
- the rod is configured to be positionable in the operative position by inserting an end thereof into the fold-down punch-out and thereby into the corrugations of the first flap and pushing the end through the first flap, across the divide and into corrugations of the second flap.

- a rod;
- the first flap including a cut-out on a distal edge thereof and providing access into corrugations of the first flap;
- the cardboard carton blank and the rod being configured such that the rod can be positioned in an operative position extending between the first and second flaps, and within corrugations of both of the first and second flaps and holding the first and second flaps in folded-down closed positions with distal edges of the first and second flaps adjacent one another, the third and fourth flaps folded inside of the first and second flaps and the rod extending across a divide between the adjacent distal edges;
- and
- the rod being configured to be positionable in the operative position by inserting one end thereof into corrugations of the second flap through a distal edge of the second flap and with an opposite rod end extending out from the second flap and then with the first and second flaps folded down and the opposite rod end in the cut-out and the rod extending across the divide, inserting an opposite rod end into the corrugations of the first flap at the cut-out.

A cardboard box construction, comprising:
- a cardboard carton blank having opposing first and second panels, opposing third and fourth panels, opposing first and second flaps, opposing third and fourth flaps, a first fold line between the first panel and the first flap, a second fold line between the second panel and the second flap, a third fold line between the third panel and the third flap, and a fourth fold line between the fourth panel and the fourth flap;
- a rod;
- a hole passing through an outwardly-disposed surface of the first flap and/or the first panel and providing access to corrugations of the first flap;
