SHEET CARDBOARD BLANK FOR TRAY INTENDED FOR PACKAGING DIFFERENT IN DIAMETER BOTTLES OR CANS, A TRAY MADE OF THIS BLANK (VARIANTS) Russian patent published in 2018 - IPC B65D5/20 

FIELD: manufacturing technology.

SUBSTANCE: sheet cardboard blank is intended for making a tray for packaging different in diameter bottles or cans and contains a rectangular-shaped bottom, which corners are beveled. Four side walls of equal height are extended from the bottom along the knuckle lines, two of the walls are located opposite to each other and are made with end flaps, which are a continuation of these walls along their length and each of them is made of two parts interconnected through a knuckle line for attachment to adjacent side walls. Each knuckle line of the side walls from the bottom is made in the form of two parallel scoring lines at a distance from one another extended along the side walls from the bevel on one side of the bottom to the bevel on the opposite side of the bottom to form the outer and inner contours of the side wall knuckle from the bottom. Length of the flap part adjacent to the side wall is made not less than the length of the bottom bevel on the side of this side wall. Knuckle lines of each end flap relative to the side wall and parts of this flap are made in the form of two parallel scoring lines at a distance from one another.
