Abstract: A plastics pour spout fitment (3) has not only a pour spour (4) thereof welded to plastics-coated paperboard packaging material (2), but also has a plunger (14) welded to a disc (8) of the material (2), the disc (8) being defined by a ring of weakening (6) in the material. Following purely linearly axially inward displacement of the plunger (14) relative to the pour spout (4), preferably followed by rotation of the plunger (14) about the axis A of the fitment (3) relative to the spout (4), to detach the disc (8) from the remainder of the material (2), the plunger (14), and thus the disc (8), are removed from the pour spout (4) as a screw cap (12) is removed from the spout (4).

Abstract: A valve device comprises a vertical, tubular housing, a vertical valve member in the housing, and a coil-form compression spring encircling the member and urging it upwardly against a valve seat in the housing lower end. The member includes an upper, obturating portion and a lower, closure portion and its internal surface includes an upper annular part which diverges downwardly at a gradually increasing angle away from the location of the obturating portion in the valve closed condition. The internal surface includes a lower annular part converging downwardly at a substantial angle to the housing axis and situated directed radially outwards of the spring. Below the seat is an outlet mouth encircled by a rim, the closure part having a bottom lip at such clearance relative to the rim that, shortly before the closure part seals against the seat, the rim and the lip act shearingly upon liquid therebetween. The member includes three guiding fins in sliding contact with the internal surface.

Abstract: A dosing device for filling liquid into containers comprises a filler body and a metering device. The metering device communicates with the interior of a rotary valve through an end cover of the valve housing, the valve including a valve seat and a check valve closure member spring-biased towards the seat. The valve includes first, second and third rotary ports and first and second fixed ports. Downstream of the second fixed port is an anti-drip suction-producing device of a piston-and-cylinder form whereof the stroke of the piston is adjustable. Upstream of the first fixed port is a throttling valve lowerable into an operative position downstream of inlet holes from a liquid-containing tank.

Abstract: A spouted, gable-topped carton has its top closure fin sealed by welding employing an ultrasonic horn and an anvil giving a suitable profile of contour sealing of the fin. There is a straight continuous lengthwise seal where the fin is two-ply and a meandering continuous lengthwise seal where it is four-ply, while the sealed portions of the four-ply spout part of the fin are of lesser total extent in proportion to the area of that spout part than are the sealed portions of the other four-ply part of the fin in proportion to its area.

Abstract: A fluid-tight sealed container with a lid is manufactured from cardboard, plastic, plastic coated cardboard or the like. The side walls of the container (1) end with a narrow rim in the opening plane of the container, against which the lid (2) is in sealing contact. At least on the portion of the lid (2) being in contact with the container rim the lid is coated with a flowable polymer coating. The rim of the container opening is melted into the polymer material to a depth that ensures sealing but still permits tearing off the lid (2). In order to permit repeated use of the lid it may be provided with a vertical flange portion (4) that is provided with symmetrically arranged bosses (5) on the side facing the side wall faces of the container (1).

Abstract: A container blank particularly suitable for carrying liquids formed from a paperboard web fed in from a roll, the upper and lower edges of which are provided with short cut lines along the score lines forming the side panels. The method for obtaining such as blank consists of a set of rectilinear cut lines spaced apart from each other in correspondence of said upper and lower edges executed at the same time as said short cut lines or during a following stage, the lips defined by short cut lines and by score lines parallel to the edges being folded over and brought into contact with the corresponding panels simultaneously with the carrying out of short cut lines or later after the side seaming of the blank; in this way the container can selectively exhibit different types of top and bottom end closures.

Abstract: A one-piece, resilient nozzle on an outlet pipe of a carton filler includes two relatively rigid flaps at opposite sides of the nozzle and two relatively flexible walls at other opposite sides of the nozzle, to form with the flaps a loop encircling the nozzle interior. The flaps are biassed, by the inherent resilience of the nozzle, about an axis perpendicular to the nozzle and parallel to linear bottom edges of the flaps into a closed position wherein those edges come together along a linear zone at the base of a downwardly converging interior space bounded by the loop.

Abstract: A wagon or trolley which is especially suited for the transport and distribution of piles of cartons or parcels of various sizes which are stacked directly on top of each other, comprising a substantially rectangular bottom and four mutually connected walls. A first wall is pivotally connected with the adjacent wall and serves as a door, the first wall being adapted to swing about a vertical axis so as to offer unrestricted loading access to the loading zone of the wagon when in open position. A second wall is provided with an upper door portion which in a removed or lowered position provides an additional access opening to the contents of the wagon without increasing the outer dimensions of the wagon, the lower portion of the second wall being permanently connected to its adjacent side walls and offering necessary safety for the objects in the wagon to be kept in position when the upper door portion of the second wall is opened.

Abstract: A method and an apparatus used for sealing a plastics lid to a container of plastics-coated paper board, the lidded container at several locations in the area which the lid joins the container, being supplied with energy in the form of electromagnetic microwaves, and the energy being absorbed in the paper board to melt for welding of the lid to the container.

Abstract: Process for the production of pressed bodies from municipal refuse or waste, especially refuse having a content of wood-based materials, plaster and animal and vegetable substances, in which the refuse is subjected to a treatment for reducing particle size as well as for the separation of metals and similar hard, inorganic fractions. After collection, the refuse is divided up without the addition of fluid and is thereafter dried in a hot gas to reduce the water content. The particles of refuse material are screened in an air stream to separate heavy fractions and thereafter are pressed to pressed bodies during the addition of an adhesive and/or binding agent.
