Definitions

  • the invention relates to the manufacture of workpieces for the production of packaging for mainly liquid, fatty and frozen foodstuffs or products containing or discharging fat and moisture.
  • the most known types of packaging in which the invention may be applied are paper cups, various containers with round or other bases, packages of various shapes for dairy products, juices and other products in which the main forming/frame element is mainly pulp and paper material or any other material requiring protection of the end-face from contact with the contents of the container.
  • a similar problem can also occur on the outer surface of the container at the seam with overlapping material. In the case of damp or aggressive environments, it may be necessary to protect the end-face of the material on the outer surface of the container.
  • One of the options for sealing the seam end-face is to lengthen the protective layer beyond the frame material and then solder it to the protective layer of the mating surface during the formation of the finished package so that the protected end-face of the frame material remains isolated from contact with the contents of the package. Lengthening of the protective layer beyond the frame material does not cause thickening of the material at the place of heat sealing with the mating surfaces, as in the case with the imposition of additional polymeric tapes or changes in technical and mechanical properties, as in the case of trimming, bending or turning under of the material.
  • the disadvantage of the above methods is the increased consumption of material, as it is required to cut windows from the frame material.
  • This invention solves the problem of creating a method of obtaining a shape-forming material with an elongated protective layer with the elimination of the above mentioned drawback.
  • the technical result is the expansion of the arsenal of technical means and the creation of a method of obtaining a shape-forming material with an elongated protective layer.
  • the technical result is achieved due to the fact that in the method of obtaining an elongated protective layer of the shape-forming material of a workpiece, in which to obtain the shape-forming material a protective layer is applied to the frame roll or sheet material, a protective layer is applied outside the frame roll or sheet material on one side or both sides to form a loose edge, not attached to the frame material, carry out the die-cutting or cutting of multilayer material on the contour of the workpiece, in the places where the elongated protective layer is obtained, die-cutting or cutting is carried out directly along the freely lying edge, taking into account the allowance for elongation of the protective layer of the workpiece.
  • the packaging is produced with the correct positioning of the contour geometry on the frame material so that an elongated protective layer is always placed outside on the edge of the frame material, a loose protective layer, not glued to the frame material, can be obtained by attaching a protective layer outside the frame material.
  • the workpieces are cut down along the required contour with an allowance for the elongation of the protective layer in the places of the future interface of the packaging surfaces during its assembly.
  • the cut is made in the places of allowance on the freely lying protective layer, not attached to the frame material.
  • the method described does not require any additional end-face protective operations, such as the application of additional materials in the form of polymeric tapes, or additional trimming, bending or turning under of the material.
  • This method is perfectly suited for the production of cups and containers with a round base. Without a thickening at the point of heat sealing, the described method is perfectly suited for further rolling of the outer edge of the cups and formation of the packaging at the point where a large number of surfaces, e.g. the bottom and the seam of the side wall of the cup, meet.
  • the method for applying the protective layer 1 envisages that the applying is carried out outside the edges of the frame material 2, which comes in the form of web fed or sheet material, to form a loose (freely lying) edge 5, not attached to the frame material 2. Then the die cutting of the workpiece contour 4 of the frame material 2 is performed. In places of formation of the elongated protective layer 3, die-cutting is made directly on the loose edge 5 taking into account the allowance on prolongation of the protective layer 3.
  • a limiting feature of the production of workpieces when using the method of applying a protective layer outside the edges of the web fed or sheet material is the need for a special arrangement of the contour of the workpieces with the orientation of their allowance only to the outer edge of the source material due to the possibility to form a loose edge of the protective layer only outside the source material.
  • the location and overlap of the workpiece material should be taken into account during future welding in order to ensure the correct formation of the container (packaging) and to protect the end-face of the frame material on the correct side of the packaging (note: as a rule, the inside of the future container).
  • this invention does not limit the protection of the end-face of the frame material in the formation of containers (packaging) only from the inner surface of the container (packaging), but can also be used to protect the end-face of the frame material from the outer side of the container (packaging).
  • a protective layer can be applied to one side of the frame material, and, if necessary, to protect the end-face of the frame material on both sides of the container, on both sides, forming in the place of formation of a loose protective layer at its soldering (gluing) among themselves self-sufficient protection of the end-frame of frame material on both sides of the container.
