Definitions

  • Artorney'-Larson, Taylor & Hinds means of a thermoplastic coating such as a microcrystalline wax.
  • the lining remains sealed over a substantial area of the board after completion of the package.
  • the package is rectangular and formed from a single unitary blank, the ends of the container being closed by flaps that have been severed from one another and, over the major portion of their area, detached from the inner lining by the heating of the thermoplastic coating which is then absorbed in the boxboard material.
  • the inner lining is sealed at each end by means'of fin seals with web-gusseted ends.
  • FIG .7' is a diagrammatic representation of FIG.7'.
  • METHOD or CARTONING This invention relates to the manufacture of packages such as carton from board material, usually in the form of thick paper or card.
  • the end of the carton is first temporarily closed by folding in the form of the laminated board as uncut scored panels including web-gussets and having a fin extension composed entirely of the laminated board, then by applying heat to the end panels the inner sheeting is heatsealed and released from the board support which is thereby unfolded whereafter the stripped portions of the board support are refolded.
  • the stripped portions of the board support are severed before being refolded to form flaps which may be adhered to each other in the conventional manner.
  • a web-gusset is formed by folding triangular-shaped flaps which are usually joined to each other.
  • the first temporary closing is done by outfolding, then by applying the heat the wax is melted on the outer folds while the inner sheeting is being heat-sealed, and then the board support which is thereby stripped from at least a portion of each of the web-gussets is opened away from the stripped and sealed inner sheeting.
  • the stripped board support is then preferably cut to form rectangular flaps which are then folded down again in the conventional manner and stuck together.
  • the heat applied to the first temporarily closed end of the carton should be insufficient to strip the inner sheeting on the undermost part of the web-gussets because this has the advantage that when the end is finally closed the inner sheeting will be better held in position.
  • FIG. 1 is a plan of a scored blank to be formed into a carton
  • FIG. 2 is a cross section through a portion of a blank such as that of FIG. 1, the section being on a slightly exaggerated scale,
  • FIGS. 3, 4, a and 5b show a series of different stages in the formation of cartons from blanks as they travel along a series of paths in a machine
  • FIGS. 6, 7, 8 and 9 are end views showing stages in the formation of a carton as it travels along the paths of FIGS. 3 and FIG. is a perspective view of a carton at a further stage in its formation.
  • the laminated board comprises an outer layer 1 of the board support having sufficient porosity to absorb a low-viscosity molten wax.
  • a layer of microcrystalline wax 2 which may be blended with the cheapest grades of paraffin.
  • Paraffin is a cheap material and is a common additive to microcrystalline wax, though its presence does not contribute to adhesiveness. In fact paraffin, when heated beyond a critical temperature, acquires an almost waterlike fluidity. Thus, for the present lamination it acts to reduce the adhesiveness of the wax, control viscosity and reduce cost. In some cases it is possible to blend a microcrystalline wax blend with a heavier viscosity additive such as Elvax (a Dupont Trade Mark).
  • a sheeting material 3 which may be a metal foil (e.g. aluminum) or a heat-sealable material such as polythene, PVDC or a polyester.
  • a coating or film 4 having thermoplastic adhesive characteristics is added.
  • the layer 4 may be a film of heat-sealable polythene, a heat-seal lacquer, or a hot melt which has been extruded onto the metal foil.
  • the thermoplastic sheeting 3 or, when the sheeting 3 is not thermoplastic, the additional layer 4, should have a higher melting temperature than the microcrystalline wax layer.
  • the layers 1, 2, 3, 4 are coextensive, that is to say they all extend over the entire area of the blank.
  • the sheeting 3 may be any suitable sheeting material resistant to the passage of fluid, fluent or migrating solids or pastes or gases.
  • the blank of FIG. 1 is one which can be folded as a webgusset either inwards or, as preferred, outwards.
  • the blank has a longitudinal sealing flap 5 for the carton side seam.
  • a back panel 6 for the carton is connected to a side panel 7 which, in turn, is connected to a face panel 8 connected to a side panel 9.
  • the single broken lines in the FIG. indicate scorings or creasings for inward folding.
  • Lines 10, 11, 12, 13 represent scores which run from opposite edges of the blank to fold lines 36, 36a.
  • the gussets are 14 and 14a.
  • the lines 10, 11, 12, 13 represent cuts that only partially penetrate the material.
  • the double broken lines represent outward folding creases.
  • the blanks are fed in series in the direction of an arrow 19 (FIG. 3) to a position A on a track 18 along which the blanks are fed continuously and uniformly by means of clips on an endless chain (not shown).
  • position B the sealing flap 5 is bent forward to break the fold at a crease 15; and a fold along a crease 16, between the side panel 7 and face panel 8, is initiated.
  • position C the fold along the crease 16 is increased and a fold on a crease 17, between the face panel 8 and side panel 9, is initiated.
  • the sealing flap 5 and the side panel 9 have been brought parallel to one another with a preliminary heating device 20 between them. Then the folded blank proceeds through positions E, F, G in which the sealing flap 5 and side panel 9 are in contact with one another while passing between two heating devices 21, 22.
  • the actual folding of the blank as it proceeds along the track 18 is effected by guide rails 23, 24, 25, 26 (FIG. 6) which are curved so as to fold the blank in the required way during its progress.
  • the heating device 22 is a high capacity device and the device 21 has a much lower capacity because the heat required on the front side, i.e. on the side panel 9, may be as much as 200 F. lower than that on the other side.
  • the purpose of this heating is two-fold. Firstly, to seal together the thermoplastic faces of the barrier sheeting 3, where these are in contact close to the lower edges of the sealing flap 5 and side panel 9.
  • the sealing of the flap 5 to the panel 9 includes the sealing of small gusset elements 14a, 37a and fin elements 40a (FIG. 1) to corresponding portions of gussets 14, 37 and fins 40 at the opposite edge of the blank.
  • the folded blank is next transferred from position l-I through position I (FIG. 4) to another straight line continuousconveyor that carries the folded blank through a series of positions J to O.
  • position J In passing through position J the opening out of the folded blank has been initiated, the lower part of the side panel 9 being separated from the barrier sheeting 3.
  • position K this movement has proceeded to such an extent that the said part of the panel 9 now projects horizontally beyond the back panel 6 as shown in FIG. 7.
  • This opening out of the folded blank is effected by guide rails 27, 28, 29, 30, 31 and a guide rail 32.
  • the mechanical action required to strip the loosened sheeting 3 from the board support is produced by the pivoting action of the rail 28.
  • sheeting 3 cause the delaminated portion of this sheeting to extend from the back panel 6 to the side panel 9 somewhat as shown at 33 in FIG. 7.
  • the projecting portion of the side panel 9 is presented to a conventional adhesive applicator 34.
  • the stripped board has now been permeated with wax, the preferred adhesive to be dispensed by the applicator 34 is hot melt.
  • An alternative method of bringing the sealing panel into contact with the side panel 9 when the blank has reached the stage of FIG. 7, consists in folding the panel 5 inwardly along the crease line so that contact between the panels 5 and 9 is automatically efi'ected when the blank assumes its correct tubular form of rectangular section, as at position 0.
  • FIG. 9 shows an end view corresponding to positioned 0.
  • This initial folding consists in turning end-panels 34 inwards about creases 35 (FIG. 1), the gussets l4 outwards about creases 36, gussets 37 inwards about creases 38 and fins 39, 40 outwards about creases 41, 42.
  • the gusset outfolding is then completed at one end which is to be the bottom end of the carton as it appears at position Q (FIG. 5A).
  • the corresponding fins 40 are folded in half at creases 43 with the two halves sealed together and the fins 39 are sealed together so as to provide a single straight fin seal running between the tips of the folded gussets. This arrangement can be seen clearly at the top end in positions V, W, X.
  • the heating for effecting the sealing of the fins and the gussets results in the microcrystalline wax in the fins and gussets 37 being absorbed by the board support so that these parts are delaminated.
  • the gussets 14 are sufficiently protected from the heat by the gussets 37 for these not to be delaminated.
  • FIG. 10 The next state which is not indicated in FIG. 5A, 5B but which occurs between positions X and Y is shown in FIG. 10. It consists in opening the board support part of the carton at its ends once more, while leaving the contents sealed in the bag constituted by the sheet material 3. This is efiected by forcing the gussets 14, at each end, back into alignment with the side panels 7, 9. The result is that each gusset becomes substantially coplanar with its two associated gussets 37 once more, as shown in FIG. 10.
  • the ends of the sealed sheeting layer are well spaced away from the comers between the end panels 34 and gussets 37. This enables a suitable knife mechanism to be used to cut these corners down as far as the creases 35, 36, so as to provide four separate flaps 44, 45, 46, 47 at each end, as shown at positions Y, and Z.
  • thermoplastic film having little or no shrink characteristics is preferred.
  • the films orientation should preferably be longitudinal, and it should have been manufactured with minimum stretching.
  • the wax layer should be such that when it is melted by heating it should have a sufficiently low viscosity to enable it to penetrate the board easily. If any is left on the surface it should be nonblocking.
  • the board support may be typical boxboard, though boards having a higher degree of bulk or increased porosity are preferred because they have greater wax-absorbing properties.
  • the method of forming a package composed of a substantially rigid material such as boxboard to the whole of one face of which a moisture-resistant flexible sheeting material has been adhered by means of a thermoplastic coating such as microcrystalline wax which comprises the steps of forming the rigid material into rectangular tubular form with the sheeting material inside, closing each end of the tubular form filling before completing the closing of the second end, each closing procedure comprising forming webgussets on each side and a fin-extension extending between and overlying the web-gussets, so that the package has a complete inner lining of the flexible sheeting material contained wholly within the whole of the rigid material, and then stripping, at each web-gusseted end, the major part of the flexible sheeting material from the rigid material, heat sealing the fin extension of the lining, folding the rigid material in the form of flaps wholly outside the lining, and adhering the respective end flaps to one another.
  • a method of forming a package composed of a substantially rigid material such as boxboard to the whole of one face of which a moisture-resistant flexible sheeting material has been adhered by means of a thermoplastic coating such as microcrystalline wax which comprises forming the rigid material into a rectangular tubular form with the sheeting material inside and with a side seam by the steps of bringing the sheeting on a sealing flap into contact face-to-face with the sheet-lining on a side panel, heating the contracting layers of sheet-lining so as to join them along areas adjacent the free area of the sealing flap and side panel and to enable the sheeting to be stripped from the board support of the side panel,
