CONTAINER AND METHOD OF ITS FABRICATION Russian patent published in 2011 - IPC B65D75/62 

FIELD: transport, package.

SUBSTANCE: proposed method comprises jointing two opposite parts that make lateral walls together to produce container with chamber. Top angular section of container has product release channel. Note here that opening line is shaped that runs via said product channel and allows container opening tab to be separated there along. Said opening line comprises initial section, limiting section and final section. Note here that initial section runs in connecting section on the channel first side and arranged to allow applying first separation force to detach said tab from container, while final section is made at a distance from initial section. Note also that to separated tab from the container, second separation force is required. Note that the distance between initial section and final section forms the space that makes limiting section arranged to allows applying third tab separation force that exceeds said first and second separation forces. Mind that proposed method comprises forming the blanket from the material with folded part that makes lateral wall arranged between the parts that make lateral walls. Note here that final section continues in connecting section on second side of the channel, opposite the first side. Then, container material is loosened at final section.

EFFECT: ease of opening and dispensing, ruling out of unintentional opening.
