  • a fifth aspect of the invention comprises a method of forming a tray from a blank, which method comprises the steps: -
  • collapsible tray and a blank 10 for forming a collapsible tray or carton made from one or more blanks of paperboard or similar foldable sheet material.
  • the collapsible tray is formed from a two part blank.
  • the first blank is shown in Figure 1 and shows outer blank 10 comprising a plurality of panels for forming the outer tray.
  • outer blank 10 comprising a plurality of panels for forming the outer tray.
  • There comprises first outer side wall panel 12, base panel 14, and second outer side wall panel 16 hingedly connected together in series along foldlines 18, 20 respectively.
  • There further comprises an inner side wall structure hingedly connected to side wall panels 16 and 12 respectively along fold lines 32 and 32a.
  • inner side wall structure there comprises a securing flap 27 and an inner side wall panel 26 hingedly connected together along fold line 30.
  • inner side wall panel 26 is connected to outer side wall panel, although in the illustrated embodiment, there may further comprise spacer panel 24 hingedly interconnecting outer side wall panel 16 to inner side wall panel 26 along fold lines 32 and 28 respectively.
  • the article retention structure 82a is formed from at least part of inner base panel 72 and, preferably, extends into inner end wall panel 74 being hingedly interconnected to the aforementioned panels along fold lines 84a and fold line 90a.
  • the article retention structure 82a is otherwise separated from inner base panel 72 and wall panel 74 along proposed cut lines 94 and 96 which extend between the opposed ends of fold lines 84a and 90a.
  • the article retention structure comprises a riser panel 86a and a tread panel 88a hingedly connected together along interrupted fold line 92a. In use, the article retention structure 82a forms a step.
  • the inner end wall panels 74, 76 are wider than base panel 72 such that the opposite ends edges 73, 75; 77, 79 of the end wall panels project outwardly beyond the side edges of the base panel and outer end wall panels 44, 46.
  • Such an arrangement allows the end edges to be engaged with the inner side panels 26, 26a respectively in a set up tray, to retain the inner end panels in position whilst the retention structures 82 are formed from the inner base and inner end panels 72; 74, 76.
  • the construction of the tray from the blank shown in Figure 1 is described by reference to Figures 3, 4 and 5. It is envisaged that the construction of a flat collapsed tray and final construction and loading of the tray of the present invention can be formed by a series of sequential folding and gluing operations which can be performed in one or more straight line machines, so that the tray is not required to be rotated or inverted to complete its construction.
  • the folding process is not limited to that described below and can be altered according to particular manufacturing requirements.
  • the side walls are first constructed, as illustrated in Figures 3 and 4 whereby the inner side wall structures of the outer tray are folded inwardly in direction X and Y, shown in Figure 3 along fold lines 32 and 32a respectively and are secured to the base panel 14.
  • securing panels 27 and 27a are secured to base wall panel 14 by glue or other suitable securing means known in the art.
  • the tray is in a flat collapsed form as shown in Figure 4 to be supplied to the user so it can be erected.
  • the outer side wall panels 12 and 16 are folded inwardly in directions W and W 1 respectively, which causes the inner and outer side wall panels to be separated and spaced therefrom by the spacer panels 24 and 24a, and because fold lines 20 and 30 are spaced.
  • This action causes the tabs 38, 40; 38a, 40a to become separated from the respective inner side wall panels 26 and 26a thereby to protrude inwardly with respect to the side walls, as shown in Figures 5 and 6.
  • the insert 70 is prevented from being separated from the tray T by the protruding tabs 61, 63, 65, 67 that are inserted into the corresponding adjacent slots S formed by cut lines 62, 62a, 64, 64a, shown in Figure 6.
  • the outer side walls 12, 16 continue to be pushed inwardly in directions W and W 1 ( Figure 5) until the side wall panels are placed in an erected condition.
  • the inner and outer side wall panels 16, 26; 12, 26a of the tray T are in a substantially perpendicular arrangement with respect to the base panel 14, as shown in Figure 6.
  • the ends of the tray T is constructed whereby the inner and outer end wall panels 72, 46 and 44, 76 are folded inwardly together along fold lines 94 and 50 respectively and thereafter the end securing flaps 56 are secured to the outer face of the end wall panels by glue or other suitable means known in the art.
  • the inner end panels 72, 76 are folded inwardly first, then securing flaps are folded inwardly to be secured to the outer face of the inner end panels, or as the case may be to the inner face of outer end panels 44, 46.
  • the tray is prevented from moving laterally with respect to the outer tray T because the edges of the inner end wall panels 72 and 76 extend beyond the inner side walls 26, 26a of the inner tray and to abut the end edges 73, 75, 77, 79 of the side wall panels.
  • the tray T is in a set up condition ready to receive an article, as shown in Figure 11.
  • One or more articles are placed on the inner tray and are retained by the article retaining structure.
  • a tray T for holding foodstuff or the like is provided which tray is formed from paperboard or like foldable sheet material and can be erected from a flat collapsed condition into a position of use and includes a double skinned zone around the side and end walls and the base wall to provide a void to receive excess liquid or exudates.
  • the tray can be erected from a flat collapsed condition into a position of use and further comprises an article retention structure struck from an end portion of inner base panel such that a part of the end portion along the inner side panel remain flat with the outer base panel and wherein an engaging tab is formed along the part of the end portion to engage the end slot in the inner side panel.
  • each void could be adapted to receive suitable absorbing material, for example absorbing stamp or bag, preferably during the initial set up process or by the application of absorbing polymer gel, for example polyacrylamide, during the set up or gluing steps of carton construction.
  • suitable absorbing material for example absorbing stamp or bag
  • polymer gel for example polyacrylamide
  • FIG. 7 it is formed from a unitary blank and is similar to the first embodiment, so like parts have been designated by the same reference with the prefix '1'. Therefore only the differences will be described in any greater detail with reference to Figure 7.
  • the insert is connected to inner side wall panel 126 along fold line 130.
  • the engaging tabs 165, 167 are formed on one side edge of the insert.
  • the slots are formed from recesses 179 and 181.
  • the tray is constructed in very similar manner to the first embodiment, so only the differences will be described.
  • the inner side wall panel 126a is folded inwardly in direction X 1 along fold line 132a and securing flap 127a is secured to base panel 114 as shown in Figure 8. Thereafter, the insert and inner side wall pand 126 are folded inwardly in direction Y 1 along fold line 132 as illustrated in Figure 9, so the tray is in a flat collapsed condition ready to be supplied to an end user as shown in Figure 10.
  • the side walls and end walls are constructed and secured together as described above to produce a tray shown in Figure 11 ready to be loaded with one or more articles.
  • the two ply embodiment hereinbefore described provides a structure that is strengthened to retain foodstuff.
  • the use of paperboard material provides an "environmentally friendly" alternative to trays formed from plastics material and the tray can include printed matter for marketing purposes, as the board can be recycled.
  • the arrangement of the panels for the tray in the embodiment described above allows printed matter to be placed on the internal and external side and end walls of the tray.
  • a further advantage of the arrangement described above is that the material used for the tray and insert can differ.
  • a different caliper of paper can be used, or the insert could be a food grade material, whilst the outer tray could be a material that is more suited to the application of printed matter.
  • hinged connection should not be construed as necessarily referring to a single fold line only: indeed it is envisaged that hinged connection can be formed from one or more of one of the following, a score line, a frangible line or a fold line, without departing from the scope of invention.
