SEALED PACKAGE CONTAINING BULK FOOD PRODUCT AND SHEET PACKAGING MATERIAL FOR MANUFACTURE OF SEALED PACKAGE CONTAINING BULK FOOD PRODUCT Russian patent published in 2022 - IPC B65D5/06 B65D5/42 B65D5/02 B65D5/74 

FIELD: packaging.

SUBSTANCE: invention relates to sealed package (1, 1', 1'', 1''') containing a bulk food product and containing lower part (3), upper part (4), and main part (5) located between lower part (3) and upper part (4) and including a set of side wall parts (6), wherein main part (5) is separated from lower part (3) and specified upper part (4) respectively with lower peripheral contour (8) and upper peripheral contour (9, 9'') passing transverse to longitudinal direction (A). In this case, each of lower peripheral contour (8) and upper peripheral contour (9, 9'') has a shape of a polyline, and it is formed by a set of contour edges (8a, 8b, 8c; 9a, 9b, 9c; 9a'', 9b'', 9c'') connected to each other. Lower part (3) contains quadrangular lower panel (10) limited with lower peripheral contour (8) and passing orthogonally to longitudinal direction (A). Upper part (4) contains quadrangular upper panel (14, 14'') limited with upper peripheral contour (9, 9'') and passing transverse to longitudinal direction (A). An area of lower panel (10) differs from an area of upper quadrangle (Q) obtained by projection, along longitudinal direction (A), of upper panel (14, 14'') on base plane (P) crossing package (1, 1', 1'', 1''') and containing at least one (9a, 9a'') of contour edges (9a, 9b, 9c; 9a'', 9b'', 9c'') of upper peripheral contour (9, 9'').

EFFECT: obtainment of a sealed package for a bulk food product.
