Definitions

  • the present invention relates to a filled and sealed package of a flexible and relatively rigid package material and more particularly to a package of the kind prepared from a tube and being sealed at least at one of its ends by flattening and sealing a marginal zone of the tube, and being thereafter exposed to such a forming operation that a package having an essentially plane top side and a straight upper side wall edge is obtained.
  • Packages of this kind which are preferably used for liquid filling material, are preferably made from packaging material coated with a thermoplastic material, e.g. polyethylene, elwax, wax or lacquer. These materials are liquid-proof in themselves and permit liquid-proof seals to be made. Such seals may be produced in a simple and inexpensive manner by pressing two surfaces of material, which are coated with a thermoplastic material, against each other while simultaneously supplying heat, whereby the coatings facing one another will fuse along the zones exposed to pressure and heat. If, for some reason, it should be considered more advantageous to unite the sealing joints by means of glue, this is also possible.
  • a thermoplastic material e.g. polyethylene, elwax, wax or lacquer.
  • An additional advantage of a package of this kind is that it can be made in a rational manner, starting from a plane web of material which is formed into a tube, said tube being then filled, divided off and sealed by successive transverse sealing operations, whereupon it is separated off and finally converted into individual package units of the intended shape.
  • Packages of this kind are known per se, and the triangular fiap corners formed at the making of the package have generally been folded in towards, and fixed against, the top side of the package in order to reduce the stacking volume required for each package. Furthermore it is known to use one of the flap corners as an emptying orifice. In these known packages the flap corner is used in such a way that the tip of the triangular flap is cut olf by means of scissors or a knife, the cut in the package material defining the length of an emptying passage which may be widened and through which filling material may be poured off.
  • the crease lines provided in the top side of the package create an emptying orifice, which is large and relatively permanent with respect to its area, due to the slot formed in the upper end wall of the package being wid ened so that it occupies a stable position of equilibrium with a rhomboidal orifice having such a size that splashing and spilling will be avoided when filling material is emptied from the container.
  • FIG. 1 shows an unopened package
  • FIG. 2 shows the package with its flap torn open and a slot formed by partly removing the sealing fin
  • FIG. 3 shows the package after the opening slot has been formed
  • FIG. 4 shows the package with its pouring spout raised
  • FIGS. 5 and 6 show methods of closing the package again.
  • the package shown in FIG. 1 consists of the side wall 1, an upper end wall 2 and a bottom portion (not shown).
  • a corner flap 4 of double-walled package material is folded about the straight side wall edge 6 and is fixed by a tearable sealing means to the side wall which is integral with the edge 6.
  • the sealing fin 3 formed when the package is shaped extends from the tip of the flap 4 and over the end panel 2 along the centre normal plane and is folded down into contact with the top sides of the end panel 2 and the flap 4.
  • the package is provided with precrease lines 5 extending from the ends of the edge 6 in over the end panel 2 to a point of intersection in the centre plane normal to the edge 6.
  • the sealing fin 3 is preferably provided with a transverse tearing notch 8 and a longitudinal tearing notch 7 disposed at the base line of the fin.
  • a tearing notch 9 is further disposed in the sealing fin proper above the fold line, and therefore no slot opening is formed when the tearing notch 9 is torn open.
  • the sealing tape holding the flap 4 close to the side wall 1 of the package is torn open and the flap is raised as shown in FIG. 2, whereupon a portion of the sealing fin is removed by tearing open the tearing notches 8 and 7, or, if there are no tearing notches, by cutting the said portion of the sealing fin by means of a pair of scissors or a knife. Due to a portion of the sealing fin being removed, e.g. by tearing open the tearing notch 7 disposed along the sealing zone, a narrow slot opening 10 is produced, as shown in FIG. 3.
  • FIG. 4 shows how the opening 10 is widened by pivoting the panels 11 located between the crease lines 6'1: and 6b and the crease lines 5 both about said crease lines and about said crease lines 6'11 and 6'b to a position where the wall portions forming the orifice 10 have no longer any tendency to return to their original positions but will snap up" into a new position of equilibrium, forming a relatively large spout 12 partly from the flap 4 and partly from the panels 11.
  • the package may be partly closed by moving the crease lines 6'61 and 6b toward one another, whereby the wall portions forming the spout 12 will snap back to their original position, whereupon the flap can be pressed fiat and the opening 10 be closed so as to form a slot.
  • the triangular flap 4 thus flattened is then folded in over the end wall 2 in accordance with FIG. 5 and is locked in the folded po sition by means of the free fin portion 13 created by the tearing notch or slot 9.
  • FIG. 6 Another way of closing the package after opening it is shown in FIG. 6, where the spout 12 is folded up by moving the edges 6a and 6'b apart while simultaneously folding them against the end Wall 2 so as to form an essentially rectangular flap which can be locked against the end wall 2 by means of the fin portion 13.
  • the prerequisite for the flap 4 being locked beneath the'fin portion 13, is, of course, that the distance between the centre of the edge 6 and the tip of the flap 4 is greater than the distance between the centre of the edge 6 and the tearing notch 8 in the sealing fin 3.
  • the renewed closing described here does not make the package liquid-proof to the extent of preventing liquid filling material from trickling out if the package is tipped over, but it prevents impurities from entering the package.
  • the package has the advantage that the spout in its raised position increases the active volume of the package, whereby the splashing space is increased and the risk of spilling on account of splashing is reduced.
  • the embodiment described and shown in the example above is particularly advantageous, as parallelepipedic packages are practical both with regard to stacking and handling.
  • other embodiments may be conceived within the scope of the inventive idea.
  • the package must not necessarily be of the type which is produced by submitting a tube to transverse sealing operations but it is possible to join separate side walls, end walls and flap portions so as to form a finished package even though such a method seems impractical.
  • the package body does not necessarily have to be of parallelepipedic shape but have any shape, provided that the side wall, whose end edge is to be contained in one plane, have a straight edge section and that at least one double-walled triangular flap having its base along the straight end edge section and a corner in the centre plane normal to this edge and integral with both the end wall and the side wall and is in communication through its interior with the cavity enclosed by the side wall.
  • a filled and sealed package of flexible and relatively rigid package material said package having a closed bottom wall, a closed substantially plane top wall, side walls and front and rear Walls, said top wall comprising side flaps extending inwardly from the upper edges of said side walls, the adjacent free edge portions of said side flaps being joined forming an outwardly extending fin, a triangular end flap comprising a layer the base of which is connected to the upper edge of said front wall and a layer formed by the folded triangular corners of said end flap, said corners being continuous with said side flaps, the adjacent free edge portions of said folded corners being joined to form a continuation of said fin formed by the edge portions of said side flaps, said end flap being folded downwardly against said front Wall and said fin being bent over parallel to said top wall and said end flap, a weakened tear line extending longitudinally of said fin from the free end of said end flap to a point on said top wall at a distance from the upper edge of said end wall slightly less than the length of said end flap, a weakened tear line extending transversely
