The present invention relates to a machine for automatic packaging of food products in cup-shaped containers grouped in a row in a cardboard support. This machine comprises essentially a device for marking the support and its associated containers, as well as a device for bending down the sides of the support to a position substantially parallel with the axis of the containers. This latter device comprises essentially a vertically movable unit including two horizontal bars vertically movable with respect to the unit and capable of passing in the intervals between two successive plates supporting the containers so as to turn down the edges of the support.
A beverage can with a protective cover, a blank for it, as well as a method and device for application of a protective cover to the lid area of a beverage can, wherein the protective cover is made of embossed aluminum foil. An essentially flat blank of the embossed aluminum foil, while covering at least the can lid, is brought into contact with the beverage can and, while being shaped in a ductile manner, is molded to at least the can lid. The cans, while in an upright position, are conveyed with a conveyor apparatus beneath a placement apparatus for blanks made of embossed aluminum foil, which placement apparatus places the blanks onto the top area of the cans while pressing them, at least partially, against the lid area and/or the can edge.
