UNPACKING ELEMENT AND METHODS OF ITS PRODUCTION Russian patent published in 2017 - IPC B65D75/58 B65D75/12 

FIELD: packaging industry.

SUBSTANCE: packaging contains a laminate from a flexible film, having at least the first and the second layers and forming a part of the inner cavity. The second layer of the laminate film has the first pair of the edge parts, forming the first end joint, the second pair of edge parts, forming the second end joint, and the third pair of edge parts, forming the longitudinal joint, extending from the first end joint upto the second end joint. The laminate has the first side, the second side and the thickness. The second side of the laminate is oriented to the inner cavity of the package. The parts for grasping are formed in the laminate adjacent to the first end joint. The part for grasping has the pull strip, having the first position, when the package is closed, and the second position when the pull strip, the part of the first film layer sealing panel and the second film layer valve is lifted up from the rest part of the package to expose the unpacking place. The outer cut to incomplete depth, passing from the first side of the laminate through at least a part of the first film layer, forms the tapered part in the first film layer for easier lifting of the first film layer sealing panel from the rest of the package. The second film layer valve and the rear edge of the pull strip are formed by the inner cuts to incomplete depth in the second side of the laminate from the flexible film through at least the part of the second film layer. The edge for grasping the pull strip is formed by the through cut of the laminate whole thickness. The through cut intersects the outer cut to incomplete depth, wherein the edge for grasping is shifted relatively to the front edge of the package.

EFFECT: simplification of the package use by easier lifting of the first film layer part from the rest of the package.
