PACKAGE AND PACKAGE COLUMN Russian patent published in 2018 - IPC B65D5/64 B65D21/28 

FIELD: package and storage.

SUBSTANCE: package is a box of parallelepiped shape made of corrugated cardboard by the method of bending parts of the sheet blank to form at least a bottom and bent lateral walls from it. At least two horizontally lying side walls of the box each have at least one horizontally extending through hole of a trapezoidal shape in plan with the arrangement of a larger base parallel to the edge of the side wall. In the area of the bottom of the box, on the side walls on which the through holes are formed, the lines of the weakened section or dissection are made to form a valve with an inflection line, which passes along the line of bending of the side wall from the bottom and having an end part of a trapezoidal shape, the smaller base of which is the line of inflection of this end portion of the valve from a portion of the valve adjacent to the side wall through the inflection line of this valve from this side wall. Distance from the upper edge of the side wall to the through hole of the trapezoidal shape in the plan is not less than the distance from the valve bend line from the side wall to the inflection line of the end part of this valve.

EFFECT: invention provides spatial strength and stability of the box column due to box interlocking with a lock.
