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.

Abstract: A blank for producing a packaging container for holding liquids includes several side panels connected to bottom folding panels by way of crease lines. The bottom panels include two main bottom panels, two fold-in panels and four generally triangular refold panels. The refold panels are disposed between the main panels and the fold-in panels. The blank also includes incision lines that extend between the free edges of the refold panels and sides of the fold-in panels. The incision lines are formed in pairs so as to define a tongue therebetween. During folding of the bottom panels for forming the container, the tongues are located inside the container bottom.

A first hinge arrangement is provided for hingedly connecting the first side wall to the bottom and a second hinge arrangement is provided for hingedly connecting the second side wall to the bottom. The hinge arrangements permit the first and second side walls to be folded inwardly toward the bottom when packages are not located in the crate. The hinge axis of the first and second hinge arrangements are positioned at elevationally different positions to that the first and second side walls can be folded inwardly toward the bottom and positioned substantially parallel to one another.

Abstract: The invention describes a liquids package comprising a tube with side walls at the ends of which there are fitted a flat bottom (3) and a top which incorporates a pourer orifice, the tube consisting of paper and the bottom (3) being so welded to the tube along part of an edge by means of a plastics rim (21) that the flat main area (14) of the bottom (3) is disposed at a distance from the outer cut edge of the tube. So that the package can also be constructed for aseptic purposes and in order to render production simple and economical, it is envisaged that the bottom (3) comprise, separate from the tube, a main area (14) of paper coated with synthetic plastics material, being provided with a metal interlining, like the tube.

Abstract: An apparatus for forming packaging material into a tubular form includes angularly disposed forming rollers for causing the longitudinal edges of the packaging material to overlap one another so that they can be sealed together. To prevent the packaging material tube from being trapped between adjacent rollers, each of the forming rollers can be provided with one straight roller edge and one chamfered roller edge. The rollers are positioned such that the chamfered roller edge of one forming roller cooperates with the straight roller edge of the adjacent roller, thereby defining a nip directed generally tangentially to an adjacent portion of the packaging material tube. Alternatively, to achieve the same objective, two different types of forming rollers can be employed, one type in which both roller edges are straight and another type in which both roller edges are chamfered. In this latter case, the two types of rollers are alternated with one another.

The double strip (5) includes two overlapping strip portions (5a and 5b) covering in an openable manner an emptying opening (4) incorporated beforehand in the container. A reclosing of the container after opening is made possible in that the bottom strip portion (5b) comprises one or more protruding parts (14) which to this end can engage detachably in one or more corresponding seats (15) formed in the upper strip portion (5a).
