Definitions

  • the present invention relates to a filled and sealed package of flexible, relatively rigid packaging material and more particularly to a package of the kind which is prepared from a tube through which filling material is fed and which is divided off through successive transverse sealing operations along narrow zones located at a distance from each other along the tube axis, and is thereupon given the desired shape and divided ofi so as to form individual packaging units by means of cuts through the said sealing zones, comprising a packaging body containing at least one essentially plane side wall panel defined by straight lines formed by folding, over which panel the package is meant to be grasped.
  • Packages of the present kind which are preferably used for liquid filling material, are preferably made from packaging material coated with some thermoplastic material, e.g. polyethylene, Elwax, wax or lacquer, which is liquid proof in itself and permits liquid-proof seals to be made in a simple and inexpensive way by pressing two material surfaces coated with thermoplastic material against each other, while heat is simultaneously supplied, whereby the coatings facing each other will fuse along the zones exposed to pressure and heat. Should it for any reason he considered more preferable to unite the sealing joints by means of glue, this is also possible.
  • some thermoplastic material e.g. polyethylene, Elwax, wax or lacquer
  • a package of the present kind can be manufactured in a practical way, starting from a plane web of material which is shaped into a tube, which is filled, divided off and sealed by successive transverse sealing operations, thereupon separated off and finally converted into individual packaging units of the desired shape.
  • Patented Oct. 18, 1966 "ice The present invention, which aims at removing the drawbacks of a package having weak walls, is characterized in that a panel of relatively rigid material, wholly or partly covering one plane side wall of the package is fixed to the plane side wall panel in order to make it rigid and thus prevent the above-mentioned rolling cracks from forming.
  • the packaging body 1 which is made from material that is relatively rigid but still flexible to such a degree that it can be formed in accordance with the method described above, is provided at the top portion of one of the narrower side walls 5 with a panel 2 of rigid material.
  • the panel 2 extends beyond the full width of the side wall 5 defined by the edge lines 6 and that it is fixed to the said side wall along a substantial portion of its surface.
  • the panel 2 As the purpose of the panel 2 is to reinforce the side wall 5 within the areas, i.e. between the edge lines 6, where a hand will grasp when the package is to be emptied of filling material, it is, of course, advisable to dispose the emptying outlet 4 of the package at the side surface of the packaging body 1 which is opposite to the side wall 5.
  • the panel 2 should be applied on the flap 3 which is folded in towards the side surface and partly concealed in the figure, so that the said flap 3, which is not very pleasing from an aesthetical viewpoint, will be concealed.
  • the side wall 5 and the flap 3 it is advisable to coat both the panel 2 and the outside of the packaging body with a thermoplastic material. This connection can be brought about by supplying heat while the said parts are being pressed against each other.
  • the panel 2 may be provided with a suitable decor or informative or advertising text.
  • This embodiment of the invention has turned out to be particularly suitable since at the manufacture of the package of the kind described in the embodiment it has previously been queried whether it is possible to use a flexible material of such a kind that it can be shaped starting from a tube, and use a material which is so rigid that rolling cracks will not appear at the side walls of the finished package when the package is grasped by the hand.
  • the reinforcing panel applied to the packaging body according to the invention it is consequently possible to use a packaging material which permits the use of a more practical and more inexpensive method of making packages by submitting a tube to transverse sealing operations, at the same time as the finished package will obtain, by the application of the reinforcing panel, an acceptable resistance to cracking within the areas where the hand will grasp the package, for instance when filling material is to be emptied from the package.
  • the reinforcing panel may have U-shape and may comprise part of the sides which are adjacent to the reinforced side wall, or the reinforcing panel may be allowed to project somewhat from the edge lines of the side wall.
  • a filled and sealed package of the kind which is prepared from a tube through which filling material is fed and which is divided oflf throughtransverse sealing operations along narrow zones located at a distance from each other along the tube axis, and is then separated so as to form individual packaging units by means of cuts through the said sealing zones, and given a parallelepipedic form, said package comprising four plane side wall panels and plane top and bottom wall panels of relatively flexible material, a first and a second of two opposite side wall panels being connected to said top wall panel by two triangular double-walled flaps, one of said triangular flaps connecting one edge of said top wall panel and the upper edge of said first side wall panel being arranged to constitute a pouring outlet for the contents of said package and .the other said two triangular flap located at the opposite edge of said top wall panel being folded downwardly against said second side wall panel, and a further reinforcing panel of relatively rigid material overlying and secured against atleast a substantial part of said second side wall panel only and covering said other triangular flap thereby to
