A multi-chamber container, such as a drinking box or a beverage can, with an educational function. The multi-chamber container is designed to provide a housing, with a sidewall extending between a bottom wall and a top wall, that can store food or beverage substances therein. The housing includes a primary chamber and at least one secondary chamber. The primary chamber is accessible via a primary opening, while each secondary chamber is individually accessible via a secondary opening. The container provides an educational function in that the primary chamber stores a desired liquid or solid material and the secondary chamber is empty. The primary and secondary openings are indistinguishable to the consumer until opened from a closed state. The selection of the primary opening corresponds to a correct answer to a question displayed on, or associated with, the container.

The present invention relates to a disposable folding paper cup that folds flat and, when unfolded by the pressing of a folded portion, has a cylindrical upper end, the paper cup comprising: a cup body, which is made of a coated paper of which the inner surface is coated with a cup body coating layer, forms a cylindrical shape when unfolded, and forms a flat surface when both sides thereof are folded at folding lines; bending lines forming oval press parts that unfold bisymmetrically around each folding line when the folding line height center portion of the cup body is pressed, and dividing the oval press parts, spaced from the upper and lower ends of the cup body, therefrom; a bottom sheet which is a coated paper having a bottom sheet coating layer formed on the surface thereof so as to be fused with the cup body coating layer at the inner side of the lower end of the cup body, of which both ends are primarily fused therewith while the bottom sheet is folded along a transverse center folding line that is upwardly convex, and which is fused with the bottom edge of the folded cup body to form a bottom fused band; and fusion columns at which the front and rear surfaces, having the folding line at the center thereof, and the bottom sheet, having the end portion fitted therebetween, form a column shape higher than the fusion height of the bottom fused band and lower than the lower end of the bending line, thereby fusing, at a portion at which the bottom fused band and the folding line meet, the end portion of the bottom sheet through the three sides altogether.

A can, and device and method for producing same, includes two circular end elements forming a base and lid. The can further includes a sleeve which has fold lines forming edges, the can sleeve having a circular cross-sectional area at both ends and a polygonal-sectional area in its central region. The polygonal cross-sectional area in the central region is at most decagonal.

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.
