• the product pieces 118 could be inserted into the fitments 132 before they are placed in the containers.
• the fitments 132 could be inserted into the containers before the end closures are formed at the first end of the containers.
• a first embodiment of a fitment 132 for use in the inner package containers is illustrated in Figure 12.
• the fitment 132 is made from a single blank of foldable material such as cartonboard or cardboard. The material is selected so that it has an inherent resilience or shape memory when folded about a fold line, at least where the fold line is not formed with a very sharp crease.
• the fitment 132 is elongate having a length approximately the same as the internal length of the containers and has a central, product retention region in the form of an inverted U shaped upstand or channel portion 196 extending in a longitudinal direction.
• the channel portion 196 includes an outer (upper as shown) end wall 198 and a pair of opposed side walls 200 depending inwardly (downwardly as shown) from the end wall.
• a number of seats 134 for receiving and holding individual product pieces 118 are spaced along the length of the channel portion 196 so that the product pieces are held in a row.
• a first side flap is connected along one edge to an inner (lower) end of one of the side walls 200 of the channel portion by a first fold line 206 which is formed into a valley fold when the fitment is viewed from in plan from above.
• the second side flap 204 is attached to the other edge of the first side flap 202 by a further fold line 208 which produces a mountain fold when the erected fitment is viewed in plan from above.
• the two resilient side flaps 202, 204 form an inverted V shape on either side of the central channel portion and due to the resilience of the material will tend to open out.
• the second side flaps 204 are resiliently biased into engagement with the side walls of the container by the first side flaps 202 and the arrangement positions the central channel portion 196 substantially centrally of the container and prevents the fitment 132 from moving about within the container.
• Each seat 134 in the central channel portion is defined by a pair of opposed rectangular recesses 210 formed in outer (upper) regions of the side walls 200 proximal to the end wall 198.
• the opposed recesses 210 merge into an "hourglass" shaped opening 212 in the end wall 198 which defines a pair of opposed flaps 214 having a semi-circular outer edge 214A on the lateral edges of the end wall 198 either side of the opening 210.
• the flaps 214 are bent inwardly about a fold line 216 from the plane of the end wall 198.
• the fitment is configured so that the flaps 214 are resiliently biased to an initial rest position at which they are inclined inwardly (downwardly) at a first angle a to the plane of the end wall.
• the product pieces 118 have a length which is greater than the width of the channel portion 196 and the seats 134 are configured so that when a product piece 118 is inserted into a seat 134, the flaps 214 are deflected inwardly (downwardly) beyond their initial rest position to allow the product piece 118 to be fully inserted until a lower surface 118A of the product piece 118 engages with and is supported by the outer ends 218 of the side walls 200 at the bottom of the recesses 210.
• the resilience of material biases the flaps 214 back towards the initial rest position so that they resiliently engage with the oppositely directed side faces 118B, 118C of the product piece 118.
• the product piece is held firmly in place between the flaps 214 and the edges 218 of the side walls at the bottom of the recesses 210 regardless of the orientation of the package assembly 10. This is particularly important as when the inner package 14 is in a closed configuration, the outermost containers 110, 116 and their products will be inverted relative to the innermost containers 112, 114 and during transit when the package assembly may be held in any orientation.
• the product pieces are spaced apart by the remaining sections of the end wall 198 between the openings 212.
• the oppositely directed side faces 118B, 118C of the product pieces that are engaged by the flaps 214 are angled towards each other in a direction from the bottom to the top of the product piece 118 as illustrated in Figure 14.
• each flap 214 is bent so as to be concave relative to the product piece 118. This produces additional room between end wall 198 and the product piece on either side in which a user can insert their fingers to grasp a product piece 118 piece.
• the flaps 214 thus have a generally ovoid shape in plan.
• the product pieces 118 may be unwrapped or they may be individually wrapped as illustrated. In an embodiment, each product piece 118 individually wrapped in a flow wrapped wrapper having transverse end seals 219 at each end which locate on either side of the central channel portion 196.
• the product pieces 118 may be chocolates such as chocolate pralines for example.
• the packaging assembly can be adapted to package a range of products, especially food products.
• a blank 220 for forming the fitment 132 is illustrated in Figure 15. The blank has first and second side flap panels 222, 224 on either side of a central channel portion panel 226.
• the fold lines 206 between the first side flap panel 222 and the central channel portion panel 226 and 208 between the first and second side flaps in this embodiment are perforated fold lines with a series of spaced cuts 227 extending partially through the material.
• a plurality of apertures 228 are spaced along the length of the central channel portion panel to define the seats 134 and the flaps 214.
• the apertures 228 form the rectangular recesses 210 in the side walls 200 and the opening 212 in the end wall when the blank is erected.
• Longitudinal fold lines 230, 232 divided the central channel portion panel into an end wall panel 234 and a pair of side wall panels 236.
• a second embodiment of a fitment 132' for use in the containers of the package assembly 10 is illustrated in Figures 16 to 18.
• the fitment 132' is similar to the fitment of the first embodiment 132 and the same reference numerals but with the addition of a dash (') will be used to indicate the same features or features which perform the same functions.
• the fitment 132' may be made from the same materials as the first fitment 132 but differs from the first embodiment in that the product retention region takes a different form and in that it has panels at either end which provide for addition structural integrity.
• the product retention region takes the form of a plurality of spaced inverted U or channel shaped supports 196'. Each support 196' has an outer (upper) end wall 198' and a pair of opposed side walls 200' depending inwardly (downwardly) from the end wall.
• a product retention seat 134' is defined in the cavity between each adjacent pair of the supports 196' and the end walls 198' are shaped so as to define a pair of flaps 214' projecting inwardly on opposing sides of each cavity so as to contact opposed walls of a product piece when inserted in a seat 134'.
• the fitment 132' is configured so that the flaps 214' are resiliently biased to an initial rest position at which they are inclined at a first angle a to the plane of the end wall about a fold line 216'.
• the fitment 132' is configured so that when a product piece 118 is inserted into a seat 134', the flaps 214' are deflected inwardly (downwardly) beyond their initial rest position to allow the product piece 118 to be fully inserted.
• the resilience of material biases the flaps 214' back towards the initial rest position so that they resiliently engage with the oppositely directed side faces 118B, 118C of the product piece 118.
• the flaps 214' have a semicircular shaped outer edge 214A' which engages with the product and they are bent about a curved fold line 216' which is advantageously curved so as to be concave relative to the product piece 118. This produces additional room between the supports 196' and the product pieces 118.
• the flaps 214' are generally ovoid in shape.
• the product supports 196' are wider and shorter than the channel member 196 in the first embodiment so that the product piece 118 itself is able to sit in the seat 134' with its lower surface 118A passing through the gap between the inner edges 202A of the first side flaps 202'.
• the seams 219' project on either side of the product supports 196' and sit on the upper surfaces of the first flaps 202' but the product is otherwise mainly supported by the flaps 214'.
• the oppositely directed side faces 118B, 118C of the product pieces that are engaged by the flaps 214' are angled towards each other in a direction from the bottom to the top of the product piece 118 (that is in a direction from inside to outside of the fitment) in a similar manner to that as discussed in relation to the first embodiment and illustrated in Figure 14.
• the ends 214A' of the flaps 214' are biased into contact with the angled side faces when the product is fully inserted into a seat 134'. Since a portion of the product below the edges of the flaps 214 A' is wider than the gap between the end edges 214 A, the product piece is firmly held in the seat 134'.
• first flaps 202' are shorter than in the first embodiment and the second flaps 204' and the inner edges 202A' of the first flaps 202' where they meet the inner ends of the side walls 200' at the fold line 206' do not contact the rear wall 122 of the container in use.
• an end support panel 240 is pivotally connected to an outer transverse edge of the end wall 198' of each of the supports 196' at either longitudinal end along a fold line 242.
• the end support panels 240 are bent down about the fold line 242 and engage with the back wall of the container to provide additional structural integrity for the product retention region.
• the end support panel 240 is suitably shaped for inclusion in the container
• the fitment 132' can be made from a blank 244 of foldable material such as cartonboard, cardboard or the like as illustrated in Figure 18.

• the apertures 228' separate the product supports 196' from each other when the blank is erected.
• Longitudinal fold lines 230', 232' divide the central product support region panel into an end wall panel 234' and a pair of side wall panels 236' for each product support 196'.
• a third embodiment of a fitment 132" for use in the package assembly 10 is illustrated in Figures 19 to 22.
• the fitment 132" is similar to the fitment of the first and second embodiments 132, 132' and the same reference numerals but with the addition of a double dash (") will be used to indicate the same features or features which perform the same functions.

• the pairs of opposed recess 266 are spaced along the length of the central product retention region.
• the recesses 266 are generally rectangular in shape when viewed from the side and are dimensioned so that a product piece 118 can be inserted in the recess so that its lower surface 118A rests on and is supported by the product support panel 258.
• the side edges 268 of the recesses are shaped and configured to snugly engage with oppositely directed side faces 118B, 118C of the product piece 118 to firmly retain the product piece in position whilst still enabling easy removal. Because the angled walls 252 and the side walls 260 are spaced apart slightly towards the bottom of the recess and the edges of both walls are profiled, there is additional support for the product piece.
• the oppositely directed side faces 118B, 118C of the product pieces that are engaged by side edges 268 are angled towards each other in a direction from the bottom to the top of the product piece 118 (that is to say in a direction from the product support panel 258 to the outer edges 256 of the angled walls 252) and the edges 268 of the recesses in the side walls and the angled walls 252 which define the sides of the recesses 266 are profiled to engage with the inclined faces 118B, 118C.
• the side edges 268 curve outwardly in a convex fashion toward the product and are configured to engaged with the side walls at a position between its bottom surface and top so that there is a portion of the product piece below the point of contact with the side edges 266 that is wider than the spacing between the side edges 266 at the point of contact. This ensures that the product pieces 118 are firmly retained in the seats 134".
