PRESSURE-RESISTANT CONTAINER
The invention relates to a can containing a liquid and/or a gaseous medium which has positive pressure or develops such during transport or storage, wherein the cylindrical can shell of the can consists mainly of paper or cardboard material and is closed at the bottom with a bottom element and at the top with a cover element, wherein the can withstands an internal pressure of at least 5 bar, wherein the innermost layer of the can shell consists of a straight-wound barrier layer having a longitudinally extending folded seam, wherein the barrier layer is a prefabricated laminate made of an inner diffusion-tight barrier film or an inner diffusion-tight barrier laminate and an outer kraft paper layer.
Inner mold tool
An inner mould tool forming part of a mould to be used during injection moulding of plastic articles, such as plastic tops for liquid food packages, is provided. The inner mould tool comprises an outer surface defining the interior surface of the plastic article to be produced, wherein the longitudinal end of the inner mould tool is provided with a bushing having a planar surface defining the longitudinal end of the inner mould tool and being configured to be in contact with mating outer mould tools during injection moulding. The bushing is provided with side walls extending from the planar surface, said side walls forming part of the outer surface of the inner mould tool.
PACKAGING MACHINE AND METHOD FOR PRODUCING PACKAGES FROM A SHEET OF PACKAGING MATERIAL
A packaging machine for producing packages (2) from a sheet of packaging material (3), said packaging material (3) comprising a plurality of marks (20) associated with corresponding portions (21) of said packaging material (3), said packaging machine comprising a working unit (30) having a track arrangement (31) and a plurality of transporting elements (32), each transporting element (32) supporting a tool (40) arranged for carrying out a working operation on said packaging material (3), said transporting elements (32) being movable on said track arrangement (31) (independently from each other, each of said transporting elements (32) comprising a sensor device (33) arranged for detecting a corresponding mark (20) and generating a signal indicating the position of said mark (20) with respect to said transporting element (32), said packaging machine further comprising a control unit arranged to control the position of said transporting element (32) along said track arrangement (31) on the basis of said signal; a method for producing packages (2) from a sheet of packaging material (3) is also disclosed.
Pressure-resistant container
A can to contain a liquid and/or a gas is closed with a bottom element and a cover element. The innermost layer is a straight-wound barrier layer having a folded seam extending in a longitudinal direction. The barrier layer includes an inner diffusion-tight layer and an outer kraft paper layer. At least two further straight-wound layers made of paper or cardboard are around the barrier layer of the can shell. Adjoining cardboard or paper surfaces of the barrier layer and a next wound layer are adhered directly to each other. Each of the two further wound layers is longitudinally wound and include in the longitudinal direction an overlapping region with itself. The overlapping region of the next wound layer adjoining the barrier layer is offset relative to the folded seam of the barrier layer and the overlapping regions of the two further wound layers are located at different peripheral regions.
Forming device, machine, packaging laminate web, forming method and process in producing packages
A forming device and method for use in a packaging machine of the type where packages are produced from a tube. The forming device comprises two opposing sealing elements between which the tube is arranged to be flat-laid and squeezed to heat the thermoplastic and obtain a first transverse seal of the tube. It further comprises two volume control elements. The forming device is characterized in that it is arranged to displace the first transverse seal off-center in relation a longitudinal axis of the first portion of the tube in a displacement direction essentially perpendicular to the first transverse seal to enable later shaping of a corresponding final package with a wall arranged with a predetermined angle of inclination in relation to the displacement direction. The invention also relates to a machine, a process and a packaging laminate.
OPENING DEVICE, METHOD FOR MANUFACTURING SUCH OPENING DEVICE AND PACKAGING MATERIAL FOR USE IN SAID METHOD
The present invention relates to an opening device comprising a first portion on one side of a fibre based packaging laminate and a second portion on an opposite side of the fibre based packaging laminate, the first and second portion being formed in one and the same piece and joined by at least one material bridge extending through the packaging laminate. The present invention also relates to a method for manufacturing the opening device and to a packaging material to be used is such a method.
Method for the manufacture of post-deformable high-pressure composite and product obtained therefrom
The present invention falls within the scope of thermo-laminated and compact high-pressure composites, namely it relates to a method for the manufacture of a post-deformable high-pressure composite, which can be used in the automotive, aircraft, railway and naval industries, as well as in the architecture and design sector, both in indoor and outdoor environments, comprising the steps of formation of a composite (1) by the arrangement of at least two layers of material, including a layer of Kraft paper sheets (3) coated with thermoplastic resin and a layer of decorative coating; the composite formed in a flat shape, when subjected to a certain temperature and pressure in a mould (4), changes in its geometry according to the shape of that mould (4). It is also an object of this invention the product obtained with the aforementioned manufacturing method.
