摘要： The invention comprises a packaging structure which hermetically encloses a product prior to initial opening. The packaging structure comprises a line of weakness which defines a removable portion and a marginal region circumscribing the removable portion. A flap having a central region and a peripheral region is affixed to the packaging structure. At least a portion of the central region of the flap is affixed to the packaging structure via permanent adhesive and is aligned with the removable portion of the packaging structure. The peripheral region of the flap is affixed to the packaging structure via peelable adhesive and is aligned with the marginal region of the packaging structure.
