Definitions

  • the cartons are usually rectangular; they have a body tray with a base and a peripheral side wall upstanding from the base, and a lid which is sealed closed to the top of the side wall by an outturned flange around at least part of the side wall periphery.
  • the lid may be formed integrally with the tray and attached along one panel of the side wall, or it may be separate from the tray and sealed to a flange provided around the whole of the side wall periphery.
  • the carton is made of an ovenable paperboard material having on one or both of its faces a plastics coating enabling it to be erected and closed by respective heat-sealing operations.
  • a blank 8 for a carton is cut from a suitable paperboard material having a heat-sealable plastics coating on the face shown, which is the face destined to form the interior of the carton.
  • the blank is generally rectangular, having a base portion 10 adapted to form a product-receiving and tray-like body for the carton, and a lid portion 12 adapted to form a lid by which the tray may be closed after product filling with a food product.
  • the base and lid portions are integrally attached along a fold line 14.
  • the base portion 10 is internally subdivided by further crease lines to form it with a rectangular base panel 16 adapted to form the base of the carton, two longer rectangular side wall panels 18 and two shorter rectangular side wall panels 19 hinged along the edges of the base panel, internally articulated gusset-folding panels 20 joining the adjacent ends of the side wall panels, and narrow flange-forming panels 22 carried by the two shorter side wall panels 19 and by the longer side wall panels 18 remote from the lid portion 12.
  • the lid portion 12 is in the form of a single rectangular panel which is attached by the fold line 14 to the second longer side wall panel 18.
  • the lid panel is internally provided with a removable or tear-away central portion 24 by offset score lines 26 and 28 which are formed in the opposite faces of the blank and shaped to provide a tear tab 29.
  • FIG. 2 shows the form of the blank 8 on entry to the apparatus which is to be described below with reference to Figs. 3 to 6.
  • the blank has been erected by conventional means (not shown) to form an open-topped tray in which the side wall panels 18 stand vertically upwards from the base panel 16 to form a continuous tubular side wall of which the flange-forming panels 22 form coplanar upward extensions; the lid 12 also extends vertically upwards at this time.
  • the gusset-folding panels 20 are folded onto themselves and located within the tray interior against the shorter side wall panels 19, to which they are attached by a heat-sealing operation; the panels 20 accordingly act in known manner to hold the side wall panels in their required wall-forming relation.
  • Fig.3 shows the general arrangement of the apparatus as a series of the erected cartons (Fig.2) passes along it.
  • the cartons which have been charged with metered quantities of the food product to be packed, arrive on a pair of continuously operating belt conveyors 30 on which they are held end-to-end, until required, by a pair of opposed stop rollers 32 engaging the lid of the foremost carton.
  • the stop rollers 32 operate intermittently to release the cartons at regular intervals so that they can be collected individually by the flights 34 of a continuously operating chain conveyor (not specifically shown for clarity), which engage behind their trailing ends.
  • a third continuously operating conveyor again mounted beneath the carton path and again not specifically shown for clarity, has alternate trailing flights 36 and forward flights 38 between which the cartons become securely held on leaving the second conveyor. The third conveyor is continued through the remaining length of the apparatus, and provides motive power and location for the cartons during the closing operations which follow.
  • a plough bar 40 by which it is progressively bent to a backwardly inclined position.
  • a restraint plate 42 which is mounted to extend along the carton path so that its undersurface can be engaged, if necessary, by the free edge of the flange-forming panel 22 which lies opposite the lid 12.
  • the forward bending of the front panel 22 is achieved by a sheet metal plate 50 supported along one edge by a shaft 52.
  • the shaft extends horizontally across and above the carton path and is driven by a motor 54 to rotate in the direction of the arrow B (Figs.5,6) through one revolution for each carton to pass, its movement being appropriately synchronised with the movement of the second and third conveyors and the stop rollers 32.
  • the hold-down member is formed as a comb, having its upstream edge 44 formed by spaced teeth 56; the plate 50 is likewise formed along its free end with teeth 58 which correspond laterally to the spaces between the teeth 56 and which are bent backwardly (in relation to the rotation of the shaft 52) at a radius 60 at which to engage the front flange-forming panel 22.
  • a further occurrence at this stage of the closing operation is the ploughing down of the third flange-forming panel 22 of the carton, that is to say, that panel 22 which extends along the side of the carton path.
  • This is achieved by a sheet metal member 62 (shown only in Figs. 5 and 6 for clarity) which is mounted beneath the hold-down plate 46 and has a cam surface 64 positioned to bend the flange-forming panel progressively downwards below the horizontal as the carton passes beneath the hold-down member.
  • the plough bar 40 is arranged to prevent the lid 12 from impeding the entry of the carton under the hold-down member 46.
  • a further plough bar 70 located further down the carton path, subsequently engages the back of the lid and is shaped so as progressively to plough the lid closed as the carton emerges from beneath the hold-down member.
  • the carton may thereafter, and as illustrated, be rotated through 90° (arrow C) and continue along the same path as before through further hot air nozzles 84A and associated compression rollers 86A, so as to bond the lid to the panels 22 along the shorter sides of the carton and thereby complete the closing operation.
  • hot air nozzles and compression rollers associated with a further conveyor (not shown) disposed at right angles to the carton path and onto which the cartons pass from the third conveyor.
  • the invention may be applied to the closing of cartons having separate lids which are to be attached by flanges around the whole of the body tray periphery.
  • separate lids are placed on erected carton body trays as the latter emerge from beneath the hold-down member 46, suitable means being provided for subsequently holding the lids down and in proper location on the flange-forming panels of the trays while pairs of opposed hot air nozzles and associated compression rollers operate to bond the flange-forming panels and lid margins together generally in the manner described with reference to the drawings.
  • the invention is not limited in application to cartons having vertical side walls as particularly described, but may be applied to cartons of which the side walls are inclined over at least part of their periphery.
