  • Patent number: 5085882
    Abstract: A method for the cooling of a heated, e.g. heat-sterilized, flow containing particles of foodstuff character is disclosed. The flow is separated into a high particle flow, and a low particle flow which is cooled separately from the high particle flow and is used later as a cooling medium for the cooling of the high particle flow. The method can be used in aseptic packaging wherein a heat-treated, cooled foodstuff product, e.g. fruit soup, vegetable soup, meat broth, etc., is packed in sterilized packing containers, or in packing containers manufactured from sterilized packing material, under aseptic packing conditions.

  • Patent number: 4838428
    Abstract: A readily openable and reclosable opening arrangement for use on a packing container comprises a pouring pipe attached to the outside of the packing container, wherein a slide is maneuverable within the pouring pipe by means of a projecting gripping element. When the slide is pushed to the open position the packing container wall is penetrated by ploughlike elements joined to the slide, so that the contents may be emptied out via the pouring pipe. The opening arrangement also may be used on packing containers which consist of several part containers whose contents may be emptied out through a joint pouring pipe.

  • Patent number: 4811849
    Abstract: A packing container of the ridge roof type of the kind which is adapted to be opened by folding out again a bellows fold (B) formed at the top closure of the container in order to form an emptying opening (16) in the shape of a pouring spout. With the object of making the container liquid-tight and at the same time easy to open perforation (15) is arranged above the said bellows fold (B) below which the sealing fin (10) delaminates when the container is opened. The seal between the material layers forming the sealing fin (10) below this perforation is considerably weaker or almost negligible compared with the seal between material layers above the tearing perforation.

  • Patent number: 4796760
    Abstract: A packing container (1) is provided with an opening arrangement comprising a pair of spaced lines of tearing perforations (8a, 8b) arranged in a wall portion of the container, the braking up of which causes the wall material between the perforations to be displaced so as to form a corresponding emptying opening when the container is opened. A hole (9) is provided extending through at least a portion of the thickness of the wall, e.g. through a central paper layer between two plastics layers, and connecting the spaced lines. An adjacent area of the wall bordering the hole is formed as a tongue (10), and a cover strip (11) being provided sealing over the hole.
