METHOD OF FABRICATING MULTILAYER CONTAINER AND ARTICLES THUS PRODUCED Russian patent published in 2012 - IPC B65D5/02 

FIELD: transport, package.

SUBSTANCE: method of producing multilayer container from single workpiece that defines lengthwise direction from on edge to opposite one. Proposed method comprises defining inner panel that, as-assembled, makes lateral walls. Note here that inner panel comprises some part of inner panel wherein every part of inner panel adjoins adjacent part of inner panel and every part of inner panel comprises one inner lateral wall in assembled state. At least, two opposite central flaps are defined. Note here that the sum of central flaps equals or is smaller than panel crosswise length from intersection with first opposite medium flap to second opposite medium flap. Very central flap comprises some flap parts wherein every part of flap adjoins flap adjacent part and every pair of opposite flaps makes one central lateral wall of the assembled container. Outer panel is defined to form container outer lateral walls. Note here that outer panel comprises some part of inner panel wherein every part of outer panel adjoins adjacent part of outer panel and every part of outer panel comprises one inner lateral wall in assembled state. At least one pair of opposite medium flaps are bent to close their edges and secured to inner panel to form intermediate sidewalls in assembly.

EFFECT: ease of fabrication, decreased amount of wastes.
