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.

Cardboard container comprising a cylindrically wound jacket with end

A folding tray is formed by a single foldable blank which includes a bottom wall, lateral walls, and corner sections. The lateral walls and corner elements include border sections which form a horizontal rim around the periphery of the tray. Each corner section includes a generally rectangular center part and a pair of transition sections on either side thereof. Each transition section comprises a pair of triangular parts joined to each other by a fold line and joined to the center part and associated lateral wall by fold lines. Between the center part and its associated border section is a lens-shaped equalizer section which avoids the creation of an abrupt angle between the center part and border section to enable the border section to lie flat in the erected tray. The equalizer section is defined by a pair of curved fold lines which converge to form points situated adjacent the respective transition sections.
