Materials and method for making a container with a locking closure
A container and a method of forming a container having a locking closure and a method of forming the locking closure. The container includes bottom, side and top walls and at least one of the walls being an opening wall formed of panels which provide an opening to an interior of the container and which overlap to provide the locking a closure of the opening wall. In a closed condition of the container, a bottommost panel of the opening wall is partially overlapped by adjacent panels of the opening wall and a topmost panel of the opening wall located opposite the bottommost panel partially overlaps the adjacent panels and the bottommost panel. A tab of the bottommost panel is lifted upwardly to partially overlap the topmost panel to form the locking closure.
1. A method of forming a locking closure of a container, the container including bottom, side, and top walls with at least one of the walls being an opening wall formed of panels which provide an opening to an interior of the container, and which panels overlap to provide a locking closure of the opening wall, the method steps comprising;
providing a first, second, third and fourth panels of the opening wall, the first panel being a bottommost panel, the second and third panels lying adjacent to opposite sides of the bottommost panel, and the fourth panel being a topmost panel;
lowering the bottommost panel to partially cover the interior of the container;
lowering the second and third panels to at least partially overlap the bottommost panel;
lowering the topmost panel to at least partially overlap the second, third and bottommost panels;
lifting a tab portion of the bottommost panel upwardly and above the topmost panel; and
positioning the lifted tab portion to lie in contact with and in an overlapping position on top of a portion of the topmost panel, thereby forming the locking closure.
2. The method of claim 1 , wherein the tab portion includes an extension portion and the topmost panel includes at least one locking portion configured to interact with the extension portion when the locking closure is formed.
3. The method of claim 1 , wherein the tab portion includes at least a first partial opening and the topmost panel includes at least a second partial opening, and the partial openings cooperate to provide access to the tab portion by a user to permit the positioning of the tab portion to lie in the overlapping position on top of the portion of the topmost panel to form the locking closure.
