Abstract: A gable top package for pourable food products comprising a gabled top portion including a front sloping top wall and a back sloping top wall joined together at a top transversal seal, wherein the gabled top portion includes a pair of lateral flaps adjacent to respective end portions of the top transversal seal and folded out of the package top volume available for the food product and delimited by the front and back sloping top walls.

Abstract: There is described a packaging machine (1) for producing sealed aseptic packages (2) of a pourable food product from a tube (3) of packaging material fed along a vertical path (A) and filled continuously with the food product. The machine (1) has gripping means (13, 14) for gripping the tube (3) at equally spaced cross sections (15); and sealing means (23, 24; 34, 35) for sealing the packaging material of the tube (3) along the cross sections (15), and in turn having a first and a second sealing device (23, 24; 34, 35) forming part of respective distinct, successive units (10, 20) of the machine (1). The first sealing device (23, 24) interacts with the cross sections (15) of the tube (3) for a time (T1) shorter than the time (T) required to achieve complete sealing of the cross sections (15), but sufficient to form respective temporary aseptic transverse sealing bands (25); and the second sealing device (34, 35) interacts with said temporary sealing bands (25) to seal them completely.

Abstract: Packaging containers for liquid contents, for example milk, are normally manufactured from laminated packaging material including a carrier or core layer of fibre material which is coated on each side with plastic layers. In order to facilitate folding of the material, this is normally provided with a pattern of weakening crease lines which facilitate the reforming into the desired packaging container configuration. A method of retroforming or calibrating a packaging container for realising more accurate final configuration, sharper fold lines and thereby for imparting to the packaging container improved steadiness and stability comprises the steps of surrounding the packaging container with a forming device adapted to the final configuration of the packaging container, and of displacing parts of the forming device towards one another so that the free space for the packaging container is briefly reduced.

Abstract: The opening device (1) for packages of pourable food products has a frame (3) connectable to a package, and a sleeve-like portion (10) defined by the frame (3) and having a circular aperture (12) provided therein. A cap (2) releasably engages the sleeve-like portion in a liquid-tight relationship therewith. A cylindrical portion (7) defined by the cap (2) is rotatably accommodatable inside the circular aperture (12), and cutting teeth (17) are connected to the cylindrical portion (7) for cutting packaging material located beneath the circular aperture (12), whereby to open a package. Cam-followers (23a-23c) connected to an inner annular wall (13) of the sleeve-like portion (10) slidebly engage cam-defining contoured slots (22a-22c) formed on the cylindrical portion, for converting unidirectional rotation of the cap (2) with respect to said frame (3), into bi-directional axial movement of the cylindrical portion with respect to the sleeve-like portion.

Abstract: Packaging containers for beverages, for example milk or juice, as well as blanks for producing the packaging containers, are often manufactured from paper-plastic laminate which, by fold forming and sealing, is given the desired container configuration, normally parallelepipedic. With the aid of a specifically designed pattern of fold or crease lines which divide the material into, for example, six side panels (1) and associated primary end panels (7) and secondary end panels (8), respectively, prismatic, preferably hexagonal containers may instead be produced using substantially known methods.

Abstract: A packing container for pressurized contents, e.g. beer or carbonated refreshing beverages, can be manufactured from different material combinations which together provide the packing container with the necessary strength as well as the required tightness for gas as well as liquid.In accordance with the invention a packing container is formed having an outer casing which has several material layers and which provides the packing container with its strength and gas-tightness, and a liquid-tight inner container of flexible plastic material. In the manufacture and filling of the packing container, the capacity of the contents is used to give off gas so as to expand the inner container until it lies closely against the outer shell and at the same time force the air out of the casing so that the packing container is rendered completely free of air.

Abstract: A package for a pressurized liquid includes an inner container for the liquid having a generally cushion-like shape made from a tubular material which is sealed transversely at its opposite ends. The tubular material is a laminate of thin plastic and metallic foil impervious to the liquid. The inner container is enclosed within an outer reinforcing casing, open at both ends, which extends for the full length of the inner container. The casing is made from a relatively stiff material and consists of paper board the outside of which is coated with a liquid-tight layer.

Abstract: In a packing container of the type comprising two sealing joints crossing each other whereby a sealing joint forms a sealing fin in which the packaging material is joined inside to outside, a ripping strip or thread is provided adjacent the inside of the sealing fin and with a portion thereof accessible from the exterior of the container.
