Definitions

  • the invention relates to a carton and in particular to a carton for the transportation and storage of perishable fruit such as bananas.
  • Such cartons are subject to a large amount of handling, and at some stages during their use they are subjected to very high compression forces.
  • the cycle begins with picking of unripe bananas in countries such as Guatemala or the
  • the local depot receives corrugated fibreboard blanks and assembles the cartons on-site. Because a particular banana transportation company may frequently change depots and because of the large number of depots involved, it is generally not practical to install expensive and sophisticated carton assembling plants at these locations. Accordingly, an important objective for such cartons is that they are simple to assemble on-site at the picking locations.
  • fruit cartons of this type have the conflicting requirements of being very simple to assemble and also of providing a very high resistance to compression forces.
  • a still further requirement of fruit cartons of this type is that they be suitable for use at the retail outlet in the destination country for displaying the goods. This criterion is becoming increasingly important as retailers demand simpler methods for handling the goods and more effective display.
  • a still further requirement for such fruit cartons is that they provide a large degree of ventilation through the carton. This is particularly important for ripening of bananas and avoiding "hot spots" arising in certain cartons on a loaded pallet. For example, if the temperature of bananas in a particular box rises by as little as 2°C relative to those around it during the ripening process, such a "hot spot” may cause premature ripening and loss of the bananas.
  • the relatively low commercial margins which are involved in purchase and distribution of bananas one will appreciate the importance of minimising the degree of damage caused by the physical handling of the produce and inconsistent ripening. If the fruit is bruised in handling heat is generated leading to inconsistent ripening. This in turn leads to problems at the point of sale as imperfections do not allow the full retailing potential to be realised.
  • the type of carton which has been used comprises two almost equal halves which are telescoped together to form the base and cover for a carton, both halves extending for the full height of the carton to provide a double wall thickness.
  • the outer carton is removed at the point of sale leaving the bananas displayed in the inner carton part.
  • the invention is directed towards providing an improved carton which provides the necessary compression strength, is relatively simple to assemble, provides a large degree of ventilation, and is simple for the retailer to use for effective display of the produce.
  • a carton comprising:- an inner carton part;
  • the inner carton part having reinforcing corner struts at the junction between adjacent walls of the inner carton part;
  • the inner carton part having flaps which overlap the corner struts on erection of the inner carton part.
  • the inner carton flaps comprise side flaps and end flaps which are overlapped, on assembly.
  • the flaps are adhesively bonded to one another, on assembly.
  • the inner carton part is erected from an inner carton blank which is formed from a unitary sheet of material such as corrugated fibre board.
  • the inner carton blank comprises ;-
  • corner strut-forming panels between adjacent side and end panels.
  • the comer strut-forming panels comprise three strut panels between adjacent side and end panels.
  • the inner carton blank includes corner strut-forming panel portions at the free ends of the inner carton blank, the comer strut-forming panel portions, on assembly, forming a fourth comer strut.
  • the comer struts extend diagonally between adjacent side and end panels.
  • the carton parts have ventilation holes which are in registry on assembly of the inner carton part to the outer carton part.
  • the carton parts have handle-forming cutouts which are in registry on assembly of the inner carton part to the outer carton part.
  • the inner carton part is telescopically engaged with the outer carton part, on assembly. Most preferably the inner carton part is removable from the outer carton part, for display.
  • the outer carton part has display indicia on an outer surface thereof which are visible when the inner carton part is removed from the outer carton part for display of produce such as bananas retained in the outer carton part.
  • the outer carton part is erected from an outer carton blank which is formed from a unitary sheet of material such as corrugated fibre board.
  • outer carton blank comprises:
  • the flaps comprise first closure flaps extending from the side panels and second closure flaps extending from the end panels, the first and second closure flaps being overlapped on assembly to substantially cover the comer struts.
  • the invention provides a carton blank formed from a unitary sheet of material such as corrugated fibre board, the carton blank comprising:-
  • the comer strut-forming panels may comprise three strut panels between adjacent side and end panels.
  • the carton blank includes corner strut-forming panel portions at the free ends of the blank, the corner strut-forming panel portions, on assembly forming a fourth corner strut.
  • the corner struts, on assembly extend diagonally between adjacent side and end panels.
  • the carton blank includes flaps which overlap the comer struts, on assembly.
  • the flaps comprise a side flap for each side panel and an end flap for each end panel.
  • the carton blank includes ventilation holes formed therein.
  • the carton blank includes handle- forming holes formed therein.
  • a further aspect of the invention provides a method of packaging fresh produce such as bananas comprising the steps of erecting an inner carton part, loading the produce onto a floor of the inner carton part, inserting an outer carton part over the inner carton part and the produce, and turning the packaged carton so that the floor of the inner carton part is uppermost.
  • the method includes the step of removing the inner carton part from the outer carton part for display at point of sale.
  • the method of packaging fresh produce utilises a carton or a carton blank according to the invention.

  • the flaps 40, 41, 42, 43 further ensure that the load is evenly applied when a number of cartons are stacked one upon another.
  • the inner carton portion 50 is first erected by opening up the blank 3 from the folded flatpack configuration of Fig. 3 with the flaps 40, 41, 42, 43 uppermost.

Abstract

Un carton (1) pour le transport et la présentation de bananes est constitué d'une partie intérieure (50) et d'une partie extérieure (25), les deux étant formées à partir de découpes de carton. La partie intérieure (50) comprend quatre cornières (36, 37) sur lesquelles des volets de fermeture (40, 41, 42, 43) sont repliés. Les cornières (36, 37) et les volets associés contribuent à la répartition de la charge lorsque plusieurs cartons sont empilés. Les parties extérieure et intérieure présentent des fentes de ventilation (13, 32) et des orifices de main (18, 33). Les régimes de bananes sont chargés dans la partie intérieure (50), les volets (40, 41, 42, 43) étant abaissés. La partie extérieure (25) vient de manière télescopique sur la partie intérieure (50). Le carton assemblé (1) est ensuite retourné et transporté jusqu'au point de vente. La partie intérieure (50) est enlevée de manière télescopique, la partie extérieure étant ainsi laissée ouverte et pouvant être utilisée pour la vente au détail.
