Push-Over Box

Abstract

The disclosure relates to a box having an inner part and an outer part for receiving the inner part in a closed arrangement of the box. The inner part has a base wall and at least two inner side walls, each inner side wall having a respective inner locking tab abutting the outside of a respective one of the at least two inner side walls and forming a respective inner locking edge. The outer part has a cover wall and at least two outer side walls, each outer side wall having a respective outer locking tab abutting the inside of a respective one of the at least two outer side walls and forming a respective outer locking edge. The inner locking edges are in engagement with the outer locking edges in the closed arrangement of the box to prevent separation of the outer part and the inner part.
