BAG AND METHOD OF ITS EMPTYING Russian patent published in 2013 - IPC B65D33/36 

FIELD: packaging industry.

SUBSTANCE: group of inventions relates to the field of storage and emptying of a product with use of a bag of tubing which has a cross-shaped bottom covered by a plate, having a rectangular shape and glued from the angled valves (11) bent along the fold lines from the narrow side walls, and the bottom valves (12) bent along the fold lines from the wide side walls. Method of emptying lies in the fact that the plate covering the bottom, starting from a narrow side wall, is extended from the respective angled valve (11) and from the part of adjacent bottom valves (12). Then the bottom valves (12) behind this angled valve are torn up transversely their free edges till the adjacent wide side wall for separation of the part (12') of the bottom valves (12), and the separated parts (12') together with the angled valve (11) are bent by unlapping from the fold lines to form a discharge chute (24) for implementing the emptying of the bag.

EFFECT: inventions provide the implementation of emptying of the bag without the use of aids in compliance with hygiene requirements.
