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.

A system and method for reducing manufacturing costs of patterned constructible utensils and improving their constructability. One constructible utensil includes a set of scores (e.g., a quad of scores including an outer pair and an inner pair, a single such pair, or other number of scores) that are shaped to converge when moving from a bowl-region towards the handle portion. The scores do not intersect but stop and produce various alterations in the converging score pattern. These alterations in the converging pattern help with propagation of a bowl-forming fold responsive to a constructing manipulation of the handle portion (e.g., folding, bending, and other operation on the handle portion and one or more scores on the handle portion).

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 container for packaging prepared foods, wine bottles, plants, and flowers suitable for use in greenhouses, floriculture, hydroponic farms, fast-food outlets, gift, and promotional packaging. The container includes but is not limited to a top, bottom, and middle section. The container is made using standard paperboard, standard die cutting equipment and standard cup forming manufacturing machinery. The container has no top rolled rim like a standard paperboard cup. The collapsible middle section is defined by cutouts that ensure that the ribs between cutouts remain separate during collapsing, facilitating radial collapsing of the middle section. Rounded top and bottom ends of the cutouts simplifying paperboard removal of paperboard from the cutouts. Fold lines are provided on the ribs to facilitate folding of the ribs during use. The container can retain water or be used without water.

The invention relates to a container for receiving contents, in particular liquid foods, having a tubular main body and having at least one molded fiber part connected to the main body, and to a method for producing such a container. For the container to be suitable for being aseptically filled with liquid or paste-like foods, the inner face of the at least one molded fiber part is coated to be gas and liquid tight. The container is produced as follows: pressing at least one molded fiber part from pulp, coating the inner face(s) of the molded fiber part or parts, providing the tubular main body, connecting the main body to the (first) molded fiber part for generating a container that is open on one side, filling the container through the open side, and closing the container by folding or by joining to the (further) molded fiber part.
