Definitions

  • the present invention relates to a packing container of the type that is manufactured from a web or a flat blank of a thermoplastic-coated carrier material by folding and hot-sealing of the packing material, the intention being to close the packing container formed after filling by means of sealing along a sealing fin which extends transversely across the packing containers.
  • a packing material which consists of a carrier layer which is coated, at least on the side which is intended to form the inside of the packing containers, with a homogeneous, heat-sealable plastic material.
  • the carrier material used most commonly is paper or cardboard and the coating material occurring most commonly is probably polyethylene, and the packing material is manufactured most fre quently in the form of a web, from which either package blanks are punched out, or from which the packing containers are made by folding the web into a tube which is then sealed along its longitudinal edges, whereupon the tube can be filled with the filling goods and be sealed up to individual packages by means of successive transverse sealings at a distance from one another.
  • packing containers are intended to be manufactured from blanks, these are punched out first, as mentioned above, from the packing material web, whereupon the said blanks are formed to packing containers by folding them along folding lines, preferably provided in advance, which facilitate the folding, and these packing containers are then closed by heat-sealing, which is made possible by virtue of the said thermoplastic coatmgs.
  • the packages of the abovementioned type which are manufactured of paper or cardboard with a thermoplastic layer of e.g. polyethylene, are relatively hard to open, however, since the carrier material layer is difficult to tear and the thermoplastic layer supplies a tough inner membrane which renders more difficult the ripping open of the packages.
  • a thermoplastic layer e.g. polyethylene
  • the carrier material layer is difficult to tear and the thermoplastic layer supplies a tough inner membrane which renders more difficult the ripping open of the packages.
  • To facilitate the opening of these known packages it is customary to arrange tearing indications in the package walls in the form of perforations partly breaking through the package walls. It has become apparent, however, that these tearing indications are not as effective as would be desired, and that it is difficult besides to arrange these tearing indications in the packing material in such a manner that an absolute guarantee exists that the packaging material will not be completely punched through.
  • the carrier material is made of polystyrene foam which is coated with one or more plastic layers of one or more thermoplastic materials which plastic layer or layers is or are given molecular orientation in a direction which coincides with the longitudinal direction of the said sealing fins.
  • the invention concerns the manner of manufacture of a packing container in accordance with the invention, which manner is characterized in that a web of polystyrene foam is coated by extrusion with one or more homogenuous layers of thermoplastic material, the coating being carried out so that the speed of the 2 web is kept higher than the speed at which the thermoplastic material issues from the extruder, which has the result that the thermoplastic layer or layers is or are subjected to a molecule-orientating stretching in connection with the coating, that the packing blanks are punched from the web, the said blanks at the punching being orientated in such a manner in relation to the web, that the parts which are intended to form the sealing fins of the packing containers are orientated in the longitudinal direction of the web.
  • FIG. 1 shows a packing material web indicating a row of packing blanks arranged one after the other
  • FIG. 2 shows a finished package and how the same is opened
  • FIG. 3 shows a method for the manufacture of'packing material for packages in accordance with the inven tion
  • FIG. 4 shows an enlarged cross-section through a packaging material web.
  • FIG. 1 shows a packing material web' 1, on which packing blanks 2 are arranged one after the other.
  • the packing blanks 2 before they are separated from the web but after the folding lines facilitating the folding have been put on the web 1.
  • the packing blanks 2 are oriented across the packing material web 1, and each packing blank 2 has four side walls 4 and a longitudinal joint section 13, which is intended to be used as a connecting section when the packing blank 2 through folding has acquired tubular shape with square or rectangular cross-section.
  • Each one of the packing blanks 2 is provided moreover with top closure sections 5,9,10, and bottom closure flaps 7,8,11.
  • the hatched areas 6 are meant to be punched away from the web and the punched away material has to be removed as unavoidable waste.
  • the top closure sections of the packing blank 2 comprise two rectangular sections 5 and two triangular sections 9, the sections 5 and 9 being joined to one another by means of triangular backfolding sections 10.
  • the rectangular sections 5 as well as the backfolding sections 10 are joined moreover to the sealing section 3.
  • the triangular sections 9 are folded in towards one another over the opening of the packing container, the backfolding sections 10 coming to be located between the rectangular sections 5 and the triangular sections 9.
  • the closure sections 3 will be placed together to form a flattened sealing fin 16.
  • the bottom of the package is formed in a similar manner as the top of the package, but with the difference that the bottom-forming flaps 7,8,11,12 are not connected to any sealing section, but the sealing of the bottom is done in that the longer of the rectangular bottom sections 8 with its outer part has to overlap the shorter rectangular flap 7 and that all the bottom-forming sections are folded together in a flat bottom which is pressed together between heated surfaces so that the thermoplastic coatings are made to melt and retain the bottom-forming sections in the position where they are inserted in each other.
  • FIG. 2a a finished package in which the folded together closure sections 3 form a sealing fin 16.
  • the sealing sections 3 are sealed to each other along a sealing region 17, which in the case shown here does not extend over the whole height of the sealing fin 16.
  • the packing material instead of cardboard is made of foamed plastic, e.g. an extruded polystyrene foam which is coated with a layer of homogeneous plastic oriented in longitudinal direction of the web the opening work will become considerably easier, owing to the fact that an extruded film of polystyrene foam will be readily tearable without any weakening being provided beforehand in the packing material.
  • This homogeneous foamed plastic layer can in fact be readily torn in orientation direction, whilst it is very difficult to rip it in other directions.
  • the packing material can very easily be torn in the direction of orientation of the homogeneous plastic layer whilst it can be torn only with difficulty in other directions.
  • the packaging blanks are punched out of a web in the manner as shown in FIG. 1, where the carrier packing material layer consists of extruded polystyrene foam and the homogeneous plastic layer consists of polystyrene film which is molecule-oriented in longitudinal direction of the web.
  • the homogeneous plastic layer in the embodiment shown here has its direction of orientation in the same direction as the length of the sealing fin 16, it becomes simple to rip off the sealing fin 16 along the area 18 below the sealing region 17, but for further facilitation of the tearing it is of course possible to provide a light perforation or slotsalong the tearing area 18.
  • the invention also relates to the manner of manufacture of a packing material of the kind which is used in packages in accordance with the invention, that is to say a packing material which consists of a web of polystyrene foam with a coat of homogeneous, moleculeoriented plastic material, which is molecule-oriented in the direction of the web.
  • the homogeneous plastic material may preferably consist of homogeneous polystyrene film and the polystyrene foam web can likewise preferably be extruded.
  • Flg. 3 is shown how a previously manufactured, extruded polystyrene foam web 30 is rolled off a cylinder and is passed over guide rolls 26,27 and subsequently underneath an extruder 31.
  • FIG. 4 is shown an enlarged cross-section through a manufactured packing material web, the polystyrene foam layer being marked 30 and the extruded and oriented homogeneous polystyrene layer marked 32.
  • polystyrene foam material is not moisture-absorbing in the same manner as paper or cardboard however, and an outside coating of plastic material is therefore not essential as a protection of the packages against atmospheric moisture.
  • a packaging container formed from a flat blank of a polystyrene foam packaging material having at least one layer of at least one homogeneous thermoplastic material thereon, the container having, at the top thereof, a sealing fin extending upwardly from the top of the package and transversely thereacross, said fin being formed by heat sealing together two sections of the blank, the improvement wherein the at least one layer of at least one homogeneous thermoplastic material on the sections forming the fin are molecularly oriented only in the longitudinal direction of the sealing fin across the top of the container, to facilitate tearing said fin to open the container.
  • thermoplastic material is selected from the group consisting of polystyrene, polyethylene and polypropylene.
  • thermoplastic material is polystyrene
