  • Patent number: 4934591
    Abstract: In a container made of surface protected cardboard, the container jacket is wound overlappingly from a flat blank, and closures are set into the jacket ends. Each closure is provided with a rim to be sealed to the jacket. The inner longitudinal edge of the jacket is covered with a protective strip folded in the shape of a U around that edge. The edge is recessed in the area of the rim to enable legs of the strip to closely approach one another whereby the rim can make a more complete sealing engagement with an inner circumference of the jacket.
