Packaging containers for liquids, such as beverages, comprise: at least one sidewall comprising an edge seal and a frangible border that intersects the edge seal, the sidewall defining a body and a hood; and a primary insert both surfaces of which are affixed to the body, the primary insert comprising a peelable seal. Upon tearing of the frangible border, the hood is separated from the body. In use, a straw contacts the primary insert and opens the peelable seal which has not been exposed to the environment until the hood is removed. |
