An overwrap container includes a base container having a first side seam on a side wall that extends along a longitudinal axis to define an internal volume, and a bottom connected to the side wall. An overwrap is positioned over the side wall of the base container and has a second side seam aligned longitudinally with the first side seam. Connecting elements are positioned between the side wall of the base container and the overwrap, and join the side wall of the base container and the overwrap together except in an area along the aligned first and second seams to define an uniform spacing extending continuously between the side wall and the overwrap forming an air gap there between.

A method and an apparatus for realizing cartons for packing includes feeding a cardboard band (2) for packing along an advancement direction (A) which is parallel to the development direction of the cardboard band (2) and making a first score line (II) and a second score line (12) on the cardboard band (2), so as: to identify a central sector; a first lateral sector (4), and a second lateral sector (5). The method further includes identifying regions of band (8) on the carton (2), making on each region of band (8) at least a first cut (21), a second cut (22), a third cut (23) and a fourth cut (24) oriented transversally so that a first closing wing (49), a first reinforcing wing (51) a second reinforcing wing (52), a second closing wing (50), a third reinforcing wing (53) and a fourth reinforcing wing (54) are defined. The band of carton (2) is cut transversally so as to separate the regions of band (8) from one another, thus obtaining cartons (I) for packing.

A device for manufacturing a double-walled paper cup by combining an inner cup and an outer cup using hot-melt comprising: an outer cup forming part which includes: a turret provided with outer cup mandrels; and an enclosing means forming an outer cup; an outer cup transporting part which includes: a rotational transporting means which has circular slits; an outer cup inserting means which inserts the outer cup into the circular slit; a shaft that moves up and down; a first pusher that firmly restrains the outer cup into the circular slit; and a second pusher for separating the outer cup from the circular slit; and an outer cup combining part which includes: a rotating table provided with rotatable inner cup mandrels; a rotating pocket which rotates the inner cup mandrel; and a first hot-melt spraying nozzle that applies the hot-melt to an outer surface of the inner cup.

A method for producing a bowl formed by a tray closed by a sealing film involves preparing a blank where a first and a second couples of crease lines delimit a bottom panel, two first and two second side walls, each first side wall provided of an internal flap and an external flap delimited by respective third and fourth crease lines, each second side wall provided of an internal flap and an external flap delimited by respective fifth and sixth crease lines, erecting the blank into a tray, folding the internal and external flaps of each first side wall about the respective third crease line and the internal and external flaps of each second side wall about the respective fifth crease line, applying adhesive on the internal and/or external flaps of each first and second side walls, folding the external flap of each first side wall about the respective fourth crease line and the external flap of each second side wall about the respective sixth crease line, forming a rim, applying adhesive on gaps between abutting ends of rims of adjacent first and second side walls, and attaching the sealing film on the rims.
