Abstract
According to an example aspect of the present invention, there is provided a paper cup comprising: a base; a sidewall; said base and said sidewall together defining a space for receiving liquid or food; an upper end portion of the cup comprising a first and second pair of opposing closure panels, whereby each panel is attached to an upper edge of the sidewall via a respective first folding line and to adjacent panels via respective second folding lines. Said panels are foldable into a closed position to form a lid of the cup. Each panel of said first pair contains two additional folding lines to enable folding inwards. Upon folding to the closed position, a first panel of said second pair is partly inserted below a second panel of said second pair, and the panels of said second pair close the upper end portion.
