FIELD: package and storage.
SUBSTANCE: present invention relates to a reusable packaging container comprising a flexible laminar material with a built-in opening element and repeated closure, containing internal structure and external structure, glued with application of permanent glue on each other, and between internal structure and external structure pattern of contact glue completely covered with permanent glue is embedded. Outer structure forms the outer surface of the packaging container, and the inner structure forms the inner surface of the packaging container. External structure comprises an external part of the valve limited by a notch line passing in the external structure, and the internal structure contains an internal part of the valve limited by a notch line passing in the internal structure. Internal notch line and the external notch line form an opening in the packaging container when said parts of the valve are bent off. At that, peripheral area of outer part of valve extends beyond the edge of inner part of valve and covers substrate of internal structure. Besides, valve inner part and valve outer part are connected by permanent glue and contact adhesive located between peripheral area of outer part of valve and substrate of internal structure, to provide possibility of attachment and repeated attachment of outer part of valve to substrate when container is used. Total thickness of the permanent glue layer and the contact adhesive within the pattern is greater than the thickness of the permanent glue layer outside the pattern.
EFFECT: disclosed is a package with possibility of repeated closing.
