APRON (VERSIONS) Russian patent published in 2011 - IPC B65D5/49 B65D85/60 

FIELD: transport, package.

SUBSTANCE: proposed apron incorporates cells for products. Note here that each cell represents a recess relative to apron top conditional plane and has bottom that makes product bearing surface and fixation surface limiting product horizontal displacements. Note also that cell fixation surface represents a cylindrical or a conical surface with its generatrix crossing cell bottom along the line that makes a guide of said cylindrical or conical surface. Note that bottom of each cell is inclined so that either plane of said bottom is flat, or bottom conditional plane wherein perimetre of actual not flat bottom is located, is arranged at acute angle α to apron conditional bottom plane. Generating lines of fixation surface of each cell are arranged at angle β to apron conditional bottom plane that varied in the range of (α+45°)≤β≤(α+135°). Note also that separation walls are arranged between cell lines to make cell fixation surface parts so that either guide of fixation surface of each cell represents a closed curve with length L₁, or guide of fixation surface of, at least, one cell of a line, represents closed curve with length L₁, while guide of fixation surface of any other cell of the line represents unclosed curve with length L₂ varying the range of 0.5L₁≤L₂<L₁, or guide of fixation surface of each cell of the line represents unclosed curve with its length L₂ varying the range of 0.5L₁≤L₂<L_1.

EFFECT: apron with higher bending strength.
