Definitions

  • the invention relates to a blank for forming a container as defined in the preamble portion of claim 1.
  • Blanks of these type are usually used for forming packaging containers containing beverages such as milk or juice, these containers being usally brick shaped or gable-topped con­tainers.
  • Packaging containers of these types are manufac­tured from a web having paper or cardboard support layers and external liquid-tight plastic layers, in some times in­cluding a layer of further material such as a aluminium foil.
  • the blanks are usu­ally cut from a continuous web which is printed and lami­nated.
  • the blank is folded along the longitudinal folding lines to form polygonal tube, usually a tube of rectan­gular or square cross section, the sealing panel is sealed or heat-welded onto a sealing area of one of the side panels, and then the bottom wall portions are folded inwardly and sealed together to form a bottom of the con­tainer. After the contents are filled into the container, to the top wall portions are folded and sealed to form a flat or gable top part of the container.
  • the following problem araises:
  • longitudinal folding lines formed by creasing, embossing etc. have already been pre-formed in these parts, and at these longitudinal folding lines the sealing panel may not lie sufficiently flat and tight against the corresponding sealing area of the side panel. Faulty or inperfect sealing may occur along these folding lines.
  • bottom- or top wall portions are folded inwardly along these longitudinal folding lines, the wall material of the overlapping sealing panel and wall panel may be folded away from each other and thereby lose their contact, where­by a leakage along said folding lines may occur.
  • gaps are provided in the lon­gitudinal folding lines at positions inside the sealing panel and the corresponding sealing area of the side wall panel,preferably along the free edge of the sealing panel, whereby the overlapping panels will come flatly and closely into contact with each other, will be perfectly sealed or heat-welded to each other even in the area of said gaps, and will maintain the tight sealing condition in said gaps even when the overlapping panels are folded along said folding lines.
  • any leakage which might occur along said longitudinal folding lines will be stopped or interrupted by virtue of the present of the aforementioned gaps.
  • a blank for a packaging container is formed out of a lenghty web 1 (usually rolled to form a roll), which is formed of paperboard both sides of which are coated with thermoplastic coating material, which web has two opposite side margin lines 11 and 12 shaped with a repeated pattern over the whole width of each piece of blank, each blank being separated by two straight parallel left and right end margin lines 9 and 10.
  • Each blank is formed such that is has four side wall panels P1, P2, P3, and P4 separated by parallel longitudinal folding lines 2, 2 and 2 ... and a longitudinal sealing panel P5 with a narrower width between the end margin line 10 and the longitudinal folding line 2 on the outside of the side wall panel P4 on the one side (right side).
  • Panels 3, 3a and 3b for forming a top lid part of packaging container are separated from the upper side of four side wall panels P1, P2, P3 and P4 by upper transverse folding lines 5, and panels 4, 4a and 4b for forming a bottom part of the packaging container are provided on the lower side by way of lower transverse folding line 6 respectively. Additionally, sealing panels 16, 16a, ... for forming a sealing fin part of the top are provided on the outside of the top lid forming panels by way of top transverse folding line 7.
  • the blank is first folded to form a square tube, so that the longitudinal folding line 2 de­fining the longitudinal sealing panel P5 is made to co­incide with the end margin line 9 of the side wall panel P1 on the side opposite to said sealing panel P5.
  • the left inner margin area of side wall panel P1 in fig. 2 is a sealing area which is inwardly overlapped by said sealing panel P5.
  • the container bottom part is then formed by folding small triangle panels 4b against the inside of respective oppo­site main bottom panels 4 provided at the lower part of the blank, said main bottom panels 4 being folded to overlap the outside of opposite large triangle panels 4a and 4a being inwardly folded, using lower transverse folding line 6 has hinges.
  • the lower side margin 12 of the blank is so formed that the boundary line 15 on the outside of main bottom panels 4 is protruding with a convex shape over the boundary line 15 ⁇ of the triangle parts 4b, whereby the bottom central parts 17 and 17 ⁇ are formed on the main bottom panels 4 between the boundary lines 15 and 15 ⁇ .
  • the central part 17 ⁇ on the one side is insertable between the opposite main bottom panel 4 and its adjoining triangle panel parts 4a and 4b.
  • This construction enables the bottom having a steady and complete sealing property to be obtained after being sealed.
  • a top lid part is sealed and formed such that small triangle panels 3b are arranged to be folded into the inside of opposite main top panels 3 at the top of tubular open packaging container (refer to fig. 2), whereby said main top panels 3 and 3 after folding are located outwardly, and opposite large triangle panels 3a are folded inwardly, respectively, by using the upper transverse folding line 5 as hinge means.
  • opposite sealing panels 16 are overlapped, welded and sealed to form a top sealed fin part with small sealing panels 16a being inter­posed therebetween (see fig. 3).
  • All the aforementioned folding lines 2, 5, 6, 7, are formed in the usual manner by creasing, embossing etc. as known in the art.
  • a packaging container (fig. 3) is formed from a tubular container material (fig. 2) in this way, the overlapped and welded part of longitudinal sealing panel P5 and the side marginal part of sealing area of opposite side wall panel P1 have to be folded at the respective positions of the three transverse folding lines 5, 6 and 7.
  • gaps or interruptions 8 of the respective folding lines 5, 6 and 7 are provided adjacent the end margin of edge so of the sea­ling panel P5 and at corresponding positions in side wall panel P1. These gaps overlie each other and enable the inside and outside panels P5, P1 along the side margin 10 of the overlapped and welded are a to be folded in a state of being flatly and closely in contact, and thus a state of close con­tact and sealing is satisfactorily maintained during fold­ding without destroying the good sealing property over the entire length of the sealing panel P5.
