DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Figure 1 shows a blank 10 which is foldable to form a carton for containing a secondary container 8 (see Figure 2B). A package 6 comprising the carton and secondary container 8 is shown in Figure 2A. Referring to Figure 1, the blank 10 is formed of paperboard; any suitable foldable sheet material can be used to form the blank 10.

The blank 10 is foldable into a partially-formed flat folded carton (not shown) that is provided to a converting plant where the partially-formed flat folded carton is erected into an open form; loaded with the secondary container 6 and closed to form the finished package 6 shown in Figure 2A. Further detail regarding the lay-out of blank 10 and the specific constructional steps required to assemble blank 10 into a carton are provided below. The description then focuses upon a co-operative opening mechanism and a reclosing mechanism provided by the present invention. Referring to Figure 1, the blank 10 comprises the following series of panels: a back panel 12; first bottom closure panel 20; first side panel 14; front panel 16; cover flap 35; second bottom closure panel 24; second side panel 18; glue flap 104 and closure panels 22, 26. The main panels of the blank 10 are connected along fold lines (depicted in Figure 1 by dashed lines) 4O₇ 44, 5O₇ 62, 64, 66, 72, 74/76 and 78/80. The specific arrangement of panels, size of panels and relative height of panels shown are illustrative only and in other embodiments the configuration of the carton blank will take alternative forms. Specifically it is envisaged that the bottom closure structure may take a variety of formats for example only two panels are required to form a bottom structure in one embodiment and in another embodiment a crash bottom structure as is known in the art is employed. The first and second side panels 14, 18 are in other embodiments co-extensive with the front and back panels 16, 12.

In addition to the main panels a second panel 32 is hinged to the back panel 12 along fold line 38. In this embodiment fold line 38 comprises an interrupted series of cut lines to enable the second panel 32 to be foldable in a 360° rotation. The cover flap 35 comprises: a first panel 30; engaging tab 37 and pull tab 36. The cover flap 35 is hinged by fold line 62 to front panel 16. First panel 30 is also hinged by fold line 60 to portion 34 of the cover flap. Portion 28 of the cover flap is provided with angled lines of demarcation or fold lines 56 and 54. These angled lines of demarcation 56, 54 converge at cutline 58. Cutline 58 defines the engaging tab 37 or first part of a locking mechanism 37. Cutline 58 terminates at each end in an arcuate cut 102 which curves oppositely to the main portion of cut line 58. The front panel 12 comprises a bonding region 90 defined by a half- depth cut line 88; a second part of a locking mechanism 84 is provided by an aperture 84 defined by cutline 86 and nick cuts 92 disposed at both upper edges of aperture 84.

Also shown on the blank 10 are areas of paperboard which are provided varnish free. Preferably the blank 10 is formed from a coated material and the coated side enables for the printing of graphics. The varnish-free patches 98 and 100 are prepared in this manner so that upon assembling the blank 10 into a carton, glue, adhesive or other bonding means can be applied to these areas and a secure bond will be achieved. In the illustration of blank 10 in Figure 1, the varnish free areas are depicted by cross-hatching. The blank 10 shown in figure 1 is "varnished side" or "coated side" facing out and the diagonal lines represent areas where glue is applied onto the opposite , non-coated, side of the blank 10.

Additionally, blank 10 shows areas where preferably adhesive, glue or other bonding means is applied during the construction of the blank 10 into a carton. These gluing areas 94, 96 are depicted by diagonal lines. In order that the blank 10 can be part assembled and then shipped in a flat-form, optional crease lines 42, 46, 48, 68, 70 are provided. By providing these optional crease lines 42, 46, 48, 68, 70, the blank 10 can be part-formed and then transported in an efficient manner.

To construct the blank 10 into a part formed carton, the blank 10 is reversed such that the "non-varnished side" of the blank 10 is facing outwards. First bottom closure panel 20 is folded upwardly about fold line 40 into face contacting relationship with back panel 12. Simultaneously or subsequently glue panel 106 is folded about fold line 42 into overlapping relationship with first bottom closure panel 20. Fold line 42 preferably comprises an alternating cut - crease line arrangement. Closure panels 22, 26 and second bottom closure panel 24 are also folded upwardly about respective fold lines 74/76, 78/80 and 64 into flat face contacting relationship with the respective side panel 14, 18 and back panel 16. Glue flap 104, together with half of closure panel 26 is then folded about fold lines 68/70 into overlapping relationship with the other half of closure panel 26 and a portion of back panel 16. Glue is then applied optionally in the configurations 94 and 96 as shown. The back panel 16 together with half of first side panel 14 and the folded second side panel 18 is then folded about crease line 46/48 such that cross-hatched (non-varnished) portions 100, 98 of the glue flap 104 and second bottom closure panel 24 are overlaid onto glued areas 94 and 96 respectively.

Preferably the above described steps of construction can be performed in a straight line machine where rotation of the blank 10 during construction is not required. However, it will be understood by one skilled in the art upon reading the foregoing that the above sequence of folding and gluing operations is optional and construction of a carton from the blank 10 may be achieved in a number of ways. Where, in other embodiments, an alternative configuration of blank 10 to that depicted in Figure 1 is provided, the construction sequence may be different to the non-limiting example described.

The flat-formed partially constructed carton formed after performing the above described steps is then supplied to another packaging line where the carton is opened, optionally, by bringing together the creased portions 46 and 68 of first and second side panels 14 and 18. This results in the automatic set-up of a composite base wall 20, 24, 22, 26. As the composite base wall 20, 24, 22, 26 is formed, the front panel 12 and back panel 16 are spaced apart. The upper portion of the carton is thereby ready to receive a secondary container δ.

In the present embodiment, the secondary container 8 is a sachet or pouch, containing articles such as truffles. The secondary container 8 is shown in Figure 2B. First and second portions Sl, S2 are joined together by a seal S. Additionally; the secondary container comprises a closed base portion and sides adjoining the first and second portions Sl, S2. It will be understood that such a secondary container 8 is likely to be flexible, non rigid and the invention is intended for delicate articles that need to be well sealed within the secondary container 8. Once the articles are retained, the secondary container 8 needs to be handled carefully to avoid damaging or spoiling of the goods contained therein. In this embodiment, the secondary container 8 is formed from a foil lined sheet material. The secondary container 8 (illustrated in an opened position in Figure 10) may be formed by sealing both ends of a cylindrical shaped portion of foil lined sheet material. At least one end of the secondary container is sealed by bonding together first and second portions Sl, S2, which portions extend (upwardly) beyond the plane of the seal S. The sealed secondary container 8 or sachet may be assembled loaded and sealed in a separate process. Alternatively, the construction of the secondary container 8; its loading and sealing may be performed in the same processing machine as that which supplies the opened cartons for loading. The sealed secondary container 8 is then loaded through the top, open end of the carton, between the front and back panels 12, 16. The secondary container is then disposed within the carton and the secondary container 8 rests on the composite bottom wall 20, 22, 24, 26.

The seal S of the secondary container 8 is shown in Figure 6. The first and second portions of the secondary container 8 that extend upward beyond the seal S are denoted by Sl and S2 (see Figure 8). In this embodiment the first and second portions Sl, S2 are bonded to the first and second panels 30, 32. This bonding step preferably is performed after the secondary package has been loaded and sealed and placed within the carton. Bonding first portion Sl to first panel 30 and bonding second portion S2 to second panel 32 is optional, though preferable. By bonding the secondary package above the seal S to the carton in this way, the first and second panels 30, 32 reinforce the secondary package in a region of focussed stress when the secondary package is being manipulated to break the seal, by pulling the first and second portions Sl, S2 apart. Nevertheless, even without bonding the first and second portions Sl, S2 to the first and second panels 30, 32, the first and second panels 30, 32 provide a more resilient and less flexible grasping point and provide a reinforcement to the first and second portions Sl, S2 of the foil secondary container 8. Once the first and second portions Sl, S2 have been bonded to the first and second panels 30, 32, or simply overlaid therewith, the construction of package 6 can be completed. The construction is completed by bringing together the first and second panels 30, 32 (and thus sandwiching the first and second portions Sl, S2, there between); applying glue to bonding region 90 and then folding the cover flap 35 and second panel 32 about fold lines 62 and 38 respectively. The second panel 32 is thereby disposed in face contacting relationship with the front panel 12 and the cover flap 35 is thereby disposed in face contacting relationship with, and bonded to, the front panel 12. The completed package 6 is shown in Figure 2A.

The package 6 is opened by breaking the bond between cover flap 35 and bonding region 90. To facilitate this, pull tab 36, defined by arcuate crease line 52 is optionally provided. The pull tab 36 can be grasped and used to lift the cover flap 35 away from the front panel 12. Additionally, the bonding region 90 by being defined by a half-depth cut 88 is weakened and the when the cover flap 35 is lifted, the fibre bond of the paperboard in the bonding region fails before the adhesive bond between the cover flap and bonding region does. The half-depth cut 88 enables the fibre bond of the paperboard to break and the cover flap 35 is then foldable about fold line 62 to open the package 6. By providing the optionally weakened arrangement 88, the fibre-bond is encouraged to break without the cover flap 35 tearing, breaking or being damaged in any other way which would prevent it being used for re-closing the carton. The opened package is shown in Figures 3 and 4. It can be seen that where the fibre bond of the paperboard has broken in the bonding region 90, paperboard has been removed from the bonding region 90 and can be seen attached to the cover flap 35. (The bonding region 90 defined by half-depth cut line 88 is optional and alternatively in other embodiments a weaker adhesive bond may be used which will break before the fibre bond of the paperboard). Other securing means for attaching the cover flap 35 to the front panel 12 which can then be broken without reducing the usefulness of the cover flap 35 for re-closing the carton can be used.

Once the package 6 has been opened, the cut-out defined by arcuate cut 82 (see Figure 4) can be used to separate the second panel 32 and first panel 30. Referring now to figures 5 - 8 the method of opening the secondary container using the carton is illustrated. A consumer grips first panel 30 and first portion Sl with a first hand Hl and simultaneously grips second panel 32 and second portion S2 using a second hand H2. Fold lines 38 and 62 are substantially parallel or aligned with the seal S. By pulling apart the first and second panels 30, 32, the seal S can be cleanly broken and the secondary package 8 opened, as shown in Figures 8 - 10. The opening O created by breaking the seal S is shown in Figure 9.

The first and second panels 30, 32 together with the body of the carton, provide reinforcement and a guide to encourage the seal S to break cleanly. Ripping or tearing of the secondary package 8 in an undesirable manner, that could result in the spilling of articles, for example truffles from the secondary package, is avoided or at least mitigated by the carton controlling the distribution of the pulling forces applied to the secondary container 8. Additionally the crease lines 38 and 62 by being substantially parallel to the seal S serve to prevent the forces applied to break the seal S from being dissipated past the seal S and serve to concentrate the applied pulling forces onto the seal S itself.

A second aspect of the invention provides a reclosing mechanism that may provide a sufficiently tight re-seal to minimise perishing of the contents. Firstly, the first and second portions Sl, S2 of the secondary container are sandwiched between the first and second panels 30, 32 (see Figure 11) and then the cover flap and second panel 32 folded into face contacting relationship with the front panel 16. The angled lines of demarcation 56, 54 can then be deployed to manipulate the first part of a locking mechanism, in this embodiment, the locking tab 37, (defined by cutline 58) into engagement with the second part of the locking mechanism, ( in this embodiment the aperture 84 and nick cuts 92) thereby engaging and locking together the cover panel 35 with the front panel 12. The re-closed package 6 is shown in Figure 12

It can be appreciated that various changes may be made within the scope of the present invention, for example, the size and shape of the panels may be adjusted to accommodate secondary containers of differing size or shape. It is envisaged that invention is applicable to types of secondary container other than that shown, for example a semi-rigid container with a weak or flexible upper portion. In other embodiments of the invention it is envisaged that the complementary locking mechanism may take different formats and the number and arrangement of panels to which the secondary container is bonded may also differ, for example; in another embodiment, the carton comprises three panels and the secondary container has three portions which are bonded to the three panels. In yet a further embodiment it is envisaged that four panels in a substantially square arrangement are provided and two opposed panels are creased to be disposed between the first and second panels. Additionally, four portions of the secondary container are provided for cooperation with the four panels. It will be recognised that as used herein, directional references such as "top", "bottom", "front", "back", "upward" "end", "side", "inner", "outer", "upper" and "lower" do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another. Any reference to hinged connection should not be construed, unless otherwise stated, as necessarily referring to a single fold line only; indeed it is envisaged that hinged connection can be formed from one or more of the following, a short slit, a frangible line and/or a fold line without departing from the scope of the invention.
