Definitions

  • the present invention relates to improvements in lidded packs and components thereof, and to the use of inwardly turned flaps of a base component of a lidded pack so as to ensure better bonding during a lidding process.
  • Figures 1A, B and 1C show respectively (i) a base blank, (ii) a base erected using adhesive (eg. hot melt adhesive) from the blank to define a base component able to be lidded, and a (iii) lid provided by a lidding blank, the lid having flanges to be hot melt or otherwise adhesively affixed to the exterior of each wall of component B.
  • adhesive eg. hot melt adhesive
  • a difficulty sometimes encountered with such a prior art arrangement is the bowing (particularly inward) that might occur at or adjacent the top of one or more of the walls when a lid as shown is being adhesively or hot melt glue attached over the filled base component.
  • the invention broadly consists in a lidded pack
  • a lidded pack comprising:
  • a base component of a square or rectangular plan periphery erected from one or more blank(s) to define a base panel two side walls and two end walls,
  • a lid component provided by a blank to define a lidding panel and four peripheral lidding flaps;
  • the flap extensions increasing the resistance of the side walls to deformation under a pressure used to adhesively engage the lidding flaps to the exterior of the side walls.
  • said base component is rectangular and the side walls are the longer opposed pair of walls and includes said flap extensions.
  • each of the side walls and the ends walls includes a said flap extension.
  • each said flap extension turns inwards along a fold line at or toward the top of a respective wall from which the flap extension is provided.
  • extension flaps are substantially horizontal after the lidded pack has been adhesively closed.
  • said walls are perforated intermittently along said foldline, such than when said extension flap is folded inwardly, a transition between said wall and said flap is, alternating along the foldline between: i) a hinged region,
  • a transverse cut edge of said wall projects upwardly through the thickness of the wall and presents an upper surface substantially flush with an upper surface of said extension flap.
  • flap extensions are each (optionally) mitre ended.
  • lid component flaps are each (optionally) mitre ended.
  • the side walls are of single panel form yet have end flaps, each of which is positioned (and preferably adhered) inwardly of the end wall panels thereby to define twin end flap reinforced end walls.
  • end flaps do not overlap in the end wall constructions.
  • said lid component is adhesively fixed to said base component, by adhesive between interior surfaces of said lidding flaps and exterior surfaces of respective base component walls.
  • said base component and said lid component are of a corrugated paperboard.
  • said corrugated paperboard on at least one of said base or said lid is of a double cushion corrugated paperboard.
  • the invention broadly consists in a method of lidding a container comprising:
  • said adhesive is a hot melt adhesive.
  • said adhesive is applied to the interior surfaces of said lidding flaps.
  • said step of providing the lidded pack with the extension flaps folded at least partially inwardly comprises folding the extension flaps to be substantially horizontal.
  • the present invention is a base component, or blank therefore, of, or suitable for, a lidded pack as claimed in any one of the previous claims.
  • the invention is base component substantially as herein described and with reference to Figure 3.
  • the invention is a blank substantially herein described and with reference to Figure 2.
  • the invention is a method of lidding a container substantially as herein described and with reference to any one or more of Figures 2-8.
  • the term "blank” refers to any sheet material appropriate for one or other of the components.
  • the blank is a corrugated board (eg. with paper liner on the outside of a single layer or multiple layer flute medium cushion).
  • a liner can be provided on one side or the other, or both, that enhances waterproofness and/ or insulation characteristics (whether that be a coating of a wax, a plastics film, metallised film or other).
  • Figure 1A to 1C are as previously defined and relate to prior art forms of containers.
  • Figure 2 is a preferred blank of the base component.
  • Figure 3 is a base component erected using adhesive from the blank of Figure 2.
  • Figure 4 is a preferred blank of the lid component.
  • Figure 5 shows a similar lid component as shown in Figure C but which is better able to be bonded by any adhesive (hot glue or otherwise) interposed (usually by application to the lidding flaps) between a lidding flap and the exterior panel of the walls of the component of Figure 3.
  • any adhesive hot glue or otherwise

  • Figure 7 is a perspective view of the lidded pack with lid adhesively fixed to the base component.
  • Figure 8 is a close-up view of the base component showing the foldline perforation detail.
  • Figure 9 is a view of an alternative pack and blank.
  • the blank for the base component of the present invention preferably of a suitable corrugated paper board but not necessarily so.
  • a suitable corrugated paper board Preferably there is a rectangular base panel 1, opposed end wall panels 2, opposed side wall panels 3, and side wall extension flaps 4.
  • Each of the side wall panels 3 has a flap extension 5 at its top. These flap extensions are shown as 5 and preferably are each mitre ended. In this embodiment, only the longer side walls include flap extensions 5. However, it will be appreciated that an alternative form is possible as shown in Figure 9. In this alternative embodiment, the end wall panels 2 also include flap extensions 6 at their tops.
  • the container has a flute run direction as indicated by arrow 20. This provides improved vertical load bearing capability in the side walls 3.
  • arrow 20 This provides improved vertical load bearing capability in the side walls 3.
  • the flute run direction may be perpendicular to that indicated as preferred.
  • the base component When erected, the base component is as shown with each of the extension flaps 5 (and/ or 6) turned upwardly.
  • the inturned flap In the case of the side walls 3, the inturned flap is from a single panel providing the wall.
  • the flap 6 In the case of the end walls, the flap 6 is from that panel 2 that is reinforced inwardly by a pair of side wall flap extensions 4.
  • the lid comprises a panel 7 that is sized and shaped to compliment the base of the container 1.
  • On each peripheral wall of the lid panel 7 are lidding flaps 9 and 10.
  • the ends of the lidding flaps 9 and 10 are mitred.
  • Figure 6 shows a lid being positioned over a base component ready for adhesively securing.
  • the lid is placed over top the open topped container (a container having the flap extensions turned inwardly).
  • the lidding flaps 9, 10 are adhesively secured to the outer surfaces of the end walls and side walls 2, 3 respectively.
  • the adhesive is of a hot melt type and is preferably applied to the inner surface of the lidding flaps 9, 10, immediately before fixing.
  • FIG. 7 shows the completed and, sealed container of the present invention.
  • a base component as depicted in Figure 3, and any suitable variation of it is better able (when a lid is glued on) to resist any tendency for the walls (3, or 2) to bow inwardly owing to an externally applied sealing pressure onto the flaps 9 and 0.
  • This resistance arises from a flap 5 (or 6), during the lidding process being inturned almost horizontally to support its foldline against bowing.
  • This better enables the flap 9 and 0 respectively to be adhered by a suitable interposed hot melt glue (usually applied on the lid flaps) against the outside of a wall panel 3 and a wall panel 2.
  • These minor box flaps provide resistance as the lid flaps are pressed against the box sides, allowing the hot-melt adhesive between the two to be pressed flat and thin, and hence cool, solidify and form a bond.
  • the fold transition at the top of the respective walls between the flap extension and wall preferably comprises an intermittent perforation arrangement.
  • the fold transition preferably alternates between hinged regions 12 and perforated regions 3.
  • the perforations 3 are preferably shaped with a substantially straight line central portion and have two short (approximately
  • the perforation is of a flat bottomed and short sided "U" shape.
  • the length of the short side is preferably approximately the thickness of the corrugated medium from which the container base is formed.
  • Preferred use of the containers is with for example chilled meat.
  • other produce can fill such a base component and be lidded (eg. fish).
