Abstract: To provide a tetrahedral shape packaging container or a tetrahedral shape packaging container method in which it prevents stored food from crushing, it maintains the freshness of the stored food or by tear-apart unsealing it can select to use as dish and it can select to reserve left-over food as it is. A tetrahedral shape bag assembly is formed by providing a left side face seam, a right side face seam opposed to the left side face seam, a fastener provided on an upper side and on an inner face of the bag assembly, and an opened lower side face of the bag assembly opposed to the fastener. The opened lower side face of the bag assembly is sealed and a wide width side face seam is formed on the bag assembly in a substantially orthogonal direction to the fastener, thereby it can obtain the tetrahedral shape packaging container having a tetrahedral shape bag assembly. The left side face seam and the right side face seam are tear apart by finger.

Abstract: The disposable cup has a bottom insert, and a substantially truncated conical body having an integral lid and a cup opening. The lid is movable between a raised position and a closed position, possibly via a semi-closed position. The lid has a free edge, with a liquid passage opening allowing liquid passage when the lid is in said closed position. The lid is foldably joined to the body along an arcuate first score line. The lid further has second score lines arranged at respective ends of the free edge, the second score lines connecting the free edge and the first score line so that, when the lid is pushed towards the cup opening, the lid flips into a position inside the cup opening, the movement of the lid being substantially aided by the folding of the lid along the second score lines.

Abstract: A process is provided for closing and hermetically sealing a bottom of a container. A cylindrical container body is provided which has an inside heat-sealable surface and an open bottom end. A flange is formed on and around the bottom end of the cylindrical container body which extends outwardly from the container body at a sharp radius of approximately 90 degrees to an outside surface of the container body and which defines a flat circular heat-sealable surface on an outer side of the flange. A generally circular membrane patch having an inside heat-sealable surface is positioned on the flat circular heat-sealable surface of the container body flange covering the open bottom end of the container body. The heat-sealable surfaces of the container body flange and the membrane patch are heat-sealed to each other for hermetically sealing the container bottom end.

Abstract: In the manufacture of paper containers, a paper jacket is wound upon a first support mandrel. The wound jacket is transferred to a second support mandrel by a transfer device. A positioning device in the form of a circular ring is situated in front of the second support mandrel. The jacket is pushed through the ring en route to the second mandrel and thus becomes aligned with said second mandrel while simultaneously being shaped in accordance with the circular cross-section of the ring to conform to the circular cross-section of the second mandrel.
