Definitions

  • Containers of this kind currently in use are usually coated with wax but this kind of container is expensive to produce because it is necessary to use a high quality cardboard and the cost of the wax and the application.
  • This kind of container does however lend itself to theformation of what has become known as a gable form of closure which is an attractive kind of closure and is capable of being provided with a pouring spout.
  • a container comprising. a carton made of cardboard or similar material andhavinga body the interior of which is lined by a bag made of heat-sealable liquid-impervious organic thermoplastic material extending outwards from the top otthe.

  • An opening 24 is formed in each seam-engaging flap 15, 16 at a position betweenthe free longitudinal edge 22 and junction 23 and presents a tearing edge 25,;
  • theuppef edge of the 'ope nin g 24, is spacedfroni the tearingedge 25 at a position which is between the tearing edge ZS-and the free longitudinal edge of the Seam engaging flap.

  • the edge 25 is an edge along which, as is described below, bag material can be torn following tearing there- 5 of together with the seannforming flap along the line of weakening 21 and the edges ZS in the seam-engaging flaps 15, in are spaced by like distances from the free longitudinal edges 22 of the said flaps.

  • the bag is'madeof'heat-sealable liquidimpervious material, preferably an organic thermoplasticv material such as polyethylene, and islpreferably made froma seamless tube.
  • the bag is so located in the carton that the mouth end of .the bag extends outwards from the top of the carton body and the bag is preferably secured to the body so that it is set up simultaneously with the setting up of the carton body.
  • the mouth of the bag is closed by infolding of the end flaps 10, 11 and 13, 14.
  • This causes the formation of a mouth-closing seam formed by the juxtaposition of the'two opposite side portions 33, 34 and the gusset-folding, FIGURE 4, of the other I side portions 35, 36, the gusset folds being disposed between the juxtaposed portions 33, 34 and folded together with the flaps 17, 18 which arefolded about the medial creases 19, 20 formed therein.
  • FIGURE'3 the. sides of the bag extending between theseam and the top of the carton body and which terminate in said opposite side portions33, 34-'-are covered and engaged by the cover flaps 10,11 which slope towards each'other from the .tops of the opposite sides 1, 3 of the carton body.
  • the side portions 35, 3610f the mouth'end of the bag are engaged.
  • the mouth portion of the bag extends beyond the free longitudinal edges 22 of the seam-engaging flaps 15, 16 and is sealed by a heat-induced bead seal 37, FIGURE 3."
  • the scaling is effected by a'bead seal because of the .thickness of the seam which for most of the length thereof consistsof four thicknesses of bag material bflt'at the centre of the seam consists, for a short distance, of only two thicknesses of bag material;
  • the bead seal ensures a completely liquid-tight seal "which could not be ensured by When it is desired to obtain access to the contents of the container the portion 38 is gripped-between a finger and-thumb of one hand and, with the other hand,
  • the lines of -weakening 21 are torn from the edges 22 down to the junctionr23.'
  • the lines ot' weakening are only two thicknesse's'of bag material and this eases the tearing of the bag material and results in tearing of the in broken lines in FIGURES'l and 6.
  • edges 25 befree to stretch in order to effect tea-ring thereof and it is for this reason that the said portions of the bag material are arranged to be unsecured to the seam-engaging flaps.

  • the tearing edges 25 are formed, by slits, instead of openings, made inthe seam-engaging flaps 15,16 and pourer-forrn- 'ing'flaps 17 and the lines of weakening 26 are formed by slits which extend from edge 22 nearly, but not quite, to 'the slits formingthe tearing edges 25.
  • adhesive is indicated by hatching and it will be noted I that no adhesive is applied to the area 46 :so that the bag portions immediately above the tearing edges 25 are not adhered to the seam-engaging flaps15, 16 or to the-pourer-forming flap 17. r
  • FIGURElO' is similar to that of FIGURE 8-but carton sides 2 and 4 are provided with crease lines 47' which permit the mouth end of the carton to be closed in a manner such that the bag-mouthclosing seam consists of only two juxtaposed oppositeportions throughout the whole length thereof. This permits the heat-sealing of the bag mouth-closing seam by a sealing device.
