CONTAINER BOX Russian patent published in 2019 - IPC B65D5/00 B65D21/02 

FIELD: package and storage.

SUBSTANCE: container in the form of a parallelepiped contains a bottom, along the perimeter, provided with supporting protrusions, made integrally with the bottom. Slit-like grooves are made along the bottom of each side to accommodate the bottom protrusions therein. Parts of the lateral sides located below the slit-like grooves are the support parts of the lateral sides. In the upper part of each side landing projections with landing recesses are formed that are located above the supporting protrusions of the support part of the lateral sides. Lateral ends of the first two opposing sides of the box are provided with connecting protrusions integrally formed with the side. Along the lateral ends on the second opposing sides, slit-like grooves are provided for placing the connecting protrusions therein. Each corner of the bottom between its adjacent sides is formed by the extreme bearing projections of said adjacent sides, integral with the bottom, in which through angular slot-like grooves are made for placing seating protrusions made in the upper part of the sides of the underlying box. In the lower part of each lateral side, near the vertical edge of the side above the level of the support part, there is a seating groove located above the corresponding angular slit-like groove of the bottom of the box for placing the seating protrusion of the underlying box therein. Planting protrusions for installation in the corresponding angled slit-like grooves of the bottom of the upper box are made in the upper part of the lateral sides above the seating groove. Box contains flat E-shaped connecting elements made of rigid material. Along the vertical edges of each side there are additional vertical grooves arranged symmetrically with respect to the corner of the box formed by adjacent sides. Additional grooves are intended for simultaneously placing the extreme sections of the E-shaped connecting elements in them and placing the central section inside the corner, the adjacent sides of which it connects.

EFFECT: invention provides better strength and reliability of the design of each individual box and a stack of boxes, better convenience in operation.
