Abstract: A method of heat-treatment of a product in a sealed container of a packaging material is described. The method includes placing the container in a treatment environment having a pressure (P) and a temperature (T), the pressure and the temperature having a ratio (P/T), and adjusting the temperature and/or pressure in the treatment environment to decrease the ratio over a duration in a time period. The time period starts at a time of cooking onset of the product and extends over a time of cooling onset at which time a temperature decrease is started, the time of cooking onset being preceded by a first time period of temperature ramping during which the temperature is increased. An apparatus for controlling heat-treatment of a product in a sealed container of a packaging material is also described.

Abstract: A method of assembling irregular tetrahedral packages having a first orientation and a mirrored second orientation, the packages each having two panels that are isosceles right triangles, and two elongated panels that are right triangles. The method involves providing an L-shaped blank having a rectangular central wall, rectangular right and left walls attached on neighboring edges of the central wall via weakening lines, arranging one package with a first orientation and one package with a second orientation on each of the right wall, left wall and central wall, wherein all packages are placed such that a panel with isosceles right triangle shape faces the cardboard blank, and where the hypotenuse of the panel is directed towards a central corner, between the right wall and the left wall, and such that the top downward angled edges of all packages also are directed towards the central corner.
