A hermetic package for a food product in liquid or pasty form and consisting of a single sheet folded along longitudinal and transversal lines of weakness to form a container having a triangular prismatic shape, of two triangular opposite parallel front walls, two opposite inclined rectangular lateral walls converging towards a common vertex, and a rectangular base wall from whose larger opposite edges extend the two front walls, whilst from the two smaller opposite edges extend the two lateral walls; first and second sealings create first and second sealing fins and define a cavity, and a single opening for accessing the cavity; the opening is made at the base wall, to allow filling of the cavity, the opening is in turn closed by a third sealing formed by sealing together inner faces of the two front walls in such a way as to create a third base sealing fin.

A method for packaging articles in a box includes the steps of depositing at least one article in a mandrel, and folding a blank around the mandrel in correspondence with at least one folding line of the blank. The blank is folded along the folding line abutting the folding line and an edge of the mandrel only for a first part of the folding line, while a second part of the folding line remains not abutted by the mandrel.

An apparatus for shaping a box by wrapping-around includes a shaping device with a carousel, on which shaping supports are circulated along a closed circular trajectory. A portion of the trajectory constitutes a box shaping path. The carousel rotates around a vertical axis of rotation with a continuous motion. The shaping supports are adapted to receive products to be packaged. The apparatus also includes a dispenser device of blanks intended to be wrapped around to contain the products to be packaged. The apparatus includes a transfer device of blanks, apt to sequentially pick-up the blanks and insert them, one at a time, into the shaping path. A process for shaping boxes by wrapping-around is also described.

A method for packaging articles in boxes includes composing a mandrel from separate units, depositing at least one article inside the mandrel, wrapping a blank around the mandrel to form a box that is at least partially closed around the article deposited in the mandrel, decomposing the mandrel in the plurality of separate units, and leaving the article inside the box. The disclosure also includes a packaging device configured to operate according to such a method.
