  • Publication number: 20110315751
    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.

  • Patent number: 7322918
    Abstract: The flexible container relating to the present invention comprises a cylindrical member (10) made from flexible film, a bottom plate member (12) which is harder than the flexible film, fitted into the inner side of a first end section of the cylindrical member (10) and fused-bonding airtightly; and a ring member (11) which is harder than the flexible film, fitted into the inner side of a second end section of said cylindrical member (10) and fused-bonding airtightly. According to this flexible container (2), it is possible greatly to reduce the volume of the container after discharging the highly viscous material from the flexible container, and it is possible to achieve small and inexpensive moulds having excellent productivity as moulding equipment for forming the bottom plate member (12) and the ring member (11), thereby achieving benefits in that the price of the equipment can be reduced significantly.

  • Patent number: 6852071
    Abstract: Systems and methods for making a paperboard container include a sidewall blank heater assembly having upper and lower sidewall blank heaters for simultaneously heating upper and lower edge strips of the sidewall blank adjacent lateral edges thereof, and a bottom sidewall seam heater for heating a generally curved strip adjacent an arcuate bottom edge of the sidewall blank simultaneously with the upper and lower edge strips. The sidewall blank is thereafter curved about a forming mandrel at a container-forming station so as to overlap the heated upper and lower edge strips of the sidewall blank to form a longitudinal container side seam, while the bottom edge of the sidewall blank is brought into contact with a paperboard bottom wall blank to form an annular container bottom seam. A bottom seam heater assembly is most preferably provided for circumferentially heating the container bottom seam simultaneously while the sidewall blank is curved about the forming mandrel at the container-forming station.

  • Patent number: 6592504
    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.

  • Patent number: 6165115
    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.
