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.

The shell part is constituted of a cylinder of molecular-oriented plastic material, and its front end closure of a curved shrunk portion of the extension of the shell part. The rear closure of the shell part is constituted of a transversely sealed portion of the shell part.
Abstract:
A method for the production of books or bound documents from a material web (4) which comprises folding lines (6,7) or perforation lines arranged at a distance from one another and whose one side possesses a thin coating of an adhesive capable of being activated, includes printing the web (4) with the desired text and subsequently folding the web together in a folding pattern. After folding together of the web (4) the adhesive is activated so that layers with adhesive facing one another are joined together to form book-pages which can be bound together in a cover (15).
Abstract:
A material (1) in the form of sheets or a web is provided with a watermarklike pattern (12) in form of a text, figure or similar identification mark visible or displayable in transmitted light by means of relieflike mechanical working off of material, for example grinding, milling etc., corresponding to the desired pattern (12).
Abstract:
The invention relates to a packing container which is intended for liquid contents and is of the type which comprises a container body with at least one straight side wall (1) and an upper end wall (2) which is joined to the side wall (1) along a folding line (5) so as to form a relatively sharp transition between the package side (1) and the end wall (2). The upper end wall (2) is provided with a hole (4) penetrating the package wall which preferably is of triangular shape and which with one of its points reaches up to the lateral edge (5) between the upper end wall (2) of the package and its side wall (1). The hole (4) is covered from the inside by a thin plastic film, and from the hole (4) emanate two diverging perforation lines (6) which extend up to a common crease line (7) arranged in the upper end wall (2). Over the hole (4) and parts of the perforation lines (6) a further cover strip (8) with a thermoplastic coating is provided. The cover strip (8) is sealed to the inner plastic film exposed in the hole (4) and, at least in the region between the crease lines (6), to the upper end wall (2).
Abstract:
A method and apparatus for manufacturing paper sheets having an appearance of being hand-made, the method comprising the steps of forming watermarks on a continuous web along longitudinal and transverse zones spaced according to the width and length of the paper sheets, drying the continuous web, crushing longitudinal and transverse regions of the dried continuous web within the watermarked longitudinal and transverse zones, respectively, tearing and separating the dried continuous web along the longitudinal and transverse crushed regions, respectively.
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 pack for liquids is made at least partially from cardboard or the like, which is impervious to liquid at least on its one surface, by virtue of a plastics coating. The pack has side walls (1-3), a bottom and a top wall (1), which are connected together at least partially by fold (9) and/or sealing seams (4), a tear-open pouring opening (6) which is disposed in the top wall (1) adjacent the edge line (9) and which is preferably covered over by a tear-off cover strip (7) and a pouring edge (8) which is disposed in one plane with the top wall (1). A separate plastics strip (10) is sealed in position in the region of the pouring opening (6), covering over same, and extends beyond the edge line (9) of the top wall (1) with an unsealed end (11), forming a pouring edge (8), and the surface of the plastics strip (10), which covers over the pouring opening (6), is stamped out, exposing the opening (6), and is laid over around the edge (12) of the opening and is sealed in position from the underside.
Abstract:
A pack for flowable material, includes a tube (1) having at least one longitudinal seam, with a base and a lid (2) mounted at its ends. The lid (2) is made of thermoplastics material without any base material, is welded to the tube (1) and has a pouring device (8). The tube (1) is made of base material such as cardboard, coated with thermoplastics material on at least one side. The lid (2) is a separate, prefabricated part fitted by means of a flange (5) engaging round the top edge (6) of the tube (1) and welded to the edge (6). This lid (2) has a part (21) of its surface at a lower level than its outer surface, with part of the lower level surface (21) extending near to the edge (6) of the tube, in such a way that the lid (2) engages round the edge (6) of the tube substantially in a U shape in the region of said part (21 ) of the lower level surface.
Abstract:
Described is a liquid pack made at least partially of cardboard, having a longitudinal weld seam (1) and two transverse weld seams (3) which are disposed in a doubled cardboard strip (2) at the top and underside of the pack, wherein disposed in the upper transverse weld seam (3) is an opening means (6) in the form of a double-ply opening strip (7) which is liquid-tight on one side and whose outward sides are connected to the inward sides of the doubled cardboard strip (2). The opening strip (7) is made of a laminated plastics material in which one layer (21) is oriented in one direction (22).In order to permit such a pack to be produced from a tubular portion, and yet have a tearing-open action which the final consumer can readily understand, in an economical fashion and with good hygenic properties, the opening strip (7) is of a U-shaped cross-section and is so arranged that the free ends of the limb portions (10, 10') of the U-shape are directed towards the interior of the pack, the limb portions of the U-shape are welded together only at the beginning and the end to provide a beginning sealing region (12) and an end sealing region (13), the beginning sealing region (12) provides a gripping tongue portion behind which it is sealed in the longitudinal sealing seam in the doubled cardboard strip, and the end sealing region (13) is also sealed in the cardboard strip in the pouring-out region of the opening means.
