METHOD FOR OPENING PACKAGING FOR CONSUMER GOODS AND PACKAGING FOR CONSUMER GOODS, AS WELL AS METHOD FOR MANUFACTURING SUCH PACKAGING Russian patent published in 2021 - IPC B65D75/20 

FIELD: unpackaging methods.

SUBSTANCE: method for opening a package that is opened by rupture, wherein the package comprises a sheet material having opposite first and second surfaces of the sheet. The first surface of the sheet is folded towards itself and sealed along the longitudinal edges of the sheet, secured to itself to form a sealing flap that seals the package along at least the transverse edge of the sheet. The containment valve contains an opening slot that extends through the containment valve and is fully positioned in the sealed portion of the containment valve. The sealing flap is folded onto the first surface of the package, providing a connection between the sealing flap and the first surface of the package, and further comprises a first flap part and a second flap part and is folded onto the first surface of the package so that the first flap part containing the opening slot is located between the second part valve and the first surface of the package. The method includes separating the sealing flap from the first surface of the package, folding the first portion of the sealing flap toward itself, thereby exposing the opening slot at the created fold of the first portion of the flap. The folded first flap portion is then ripped open adjacent to the opening in opposite directions, thereby opening the sealing flap and the package by rupture to gain access to the contents of the package.

EFFECT: invention provides simple and easy opening of the package without the possibility of accidental opening and deterioration of the sealing properties of the packages.
