Description

Packaging

Technical Field of the Invention

The present invention relates to packaging.

Background to the Invention

A wide variety of different types of packaging are used to package products including food products such as confectionery product pieces including chocolates, pralines, candies, toffecs. and the like, and bakery or other snack type food products including biscuits, cakes and the like. The type of packaging used may be dependent on the nature of the product but can also be dependent on the way in which the product is to he marketed. For example, packaging for products that are intended to he given as gifts will tend to be more substantial and aesthetically pleasing than packaging ol similar types products intended for everyday consumption.

One type of packaging used to package confectionery products that may be given as a gift or which are intended for sharing are cartons made from cartonboard or similar materials. The cartons arc typicafly formed by assembly of corresponding carton blanks through a series of folds to provide the required carton shape defining an interior void for the containment, of the item or items to be packaged. In one known arrangement. the product pieces are individuafly wrapped and packed together loosely within a carton. Once the carton is opened. product pieces can be removed individua'ly from the carton and the carton reclosed. Where the carton contains a range of different product pieces. for example a selection of different chocolates or candies, it is necessary to search through the container to find any particular type of product piece. In particular for higher end products. it is often desirable that each product piece is individually held and presented within a container for ease of selection. For example, it is well known to package pieces of confectionery such as chocoatcs and snack products including biscuits in a box containing at least onc tray having open topped recesses to accommodate individual or, in the case of biscuits for example, a small stack of product pieces. Whflst this known arrangement presents each product piece individually in a particular location for selection when the box is opened. the product pieces are not securely held within the tray and may become dislodged or damaged during transit, especially ii the box is not retained in an upright orientation.

There is a need therefore for an alternative packaging arrangement in which a p'urality of product pieces are held which overcomes, or at least mitigates. somc or all of the drawbacks of the prior art packaging arrangements.

A non-limiting embodiment of a packaging assembly 10 in accordance with an aspect ol the invention is illustrated in the accompanying Figures and comprises an outer sleeve 12 and an inner package 14 which is received within the outer sleeve when it is in a closed configuration.

The sleeve 12 is a hollow rectangular prism in shape in shape having a front wall 16 and a rear wall 18 interconnected by opposed side walls 20, 22. The upper end of the sleeve 12 is closed by an end closure which forms an upper wall 24. The lower end 26 of thc slccvc is open so that the inncr package 14 can be inserted into and removed from the sleeve 12 through the open lower end. Whilst the sleeve 12 is rectangular in the present embodiment with the front and rear walls 16, 18 having a greater width than the side walls 20, 22, the sleeve 12 could be any suitable shape to receive the inner package 14 in its closed configuration. The outer sleeve 12 could for example be any parallelepiped shape such as a hollow square prism or curved shapes such as a cylinder.

The outer sleeve 12 can be made from any suitable material but in an embodiment is made from a single blank 30 of foldable material such as cartonhoard, cardboard or the like. The material of the blank 30 may printed on its outer surface and the blank 30 is advantageously configured so that in the completed sleeve 12, there are a minimum. (e.g. one or none) of exposed cut or raw edges of the material showing. The blank 30 is shown in Figure 2 and comprises from right to left, a first side wall panel 32. a front wall panel 34. a second side wall panel 36, a rear wall pand 38 and a glue tab 40, the panels and tab being separated by respective longitudinal fold lines 42, 44, 46 and 48. Adhesive 50 is applied to the outer surface of the glue tab 40. A respective fold over flap 52, 54, 56, 58 is attached by means of further respective fold transverse line fold lines 60, 62, 64, 66 to the lower end of each of the front, rear and side wall panels. Adhesive 68 is applied to the inner surface of each of the fold over flaps 50, 52, 54. 56.

A closure 70 for the upper end of the sleeve 12 is defined in the blank by means of a end closure panel 72 connected to an upper edge of the front wall panel 34 by means of a fold hne 74. The end cthsure panel 72 is shaped and dimensioned so as to cover substantially the whole of the upper end of the sleeve when the blank is erected. hi the centre of the end closure panel 72 is a slit 76 through which a looped ribbon 77 for the sleeve can he inserted so as to project upwardly in the completed sleeve. The ribbon 77 has flaps that »=ue secured to the inner surface of end closure panel 72 so as to form generally a T shape. A cover panel 78 is connected with the freed edge of the end dosure panel 72 opposite from the front wail panel 34 by means of a further fold line 80. The cover panel is substantially the same size as the end closure panel 72 and may he printed on its outer surface. The cover panel 78 is adapted to be folded inwardly about fold line 80 so as to overlie the inner surface of the end closure panel 72 after the ribbon has been secured in place so as to cover the inner surface of the end closure pand 72 and hide the inner attachment of the ribbon.

A pair of side closure panels 82, 84 are foldably connected to opposite side edges of the end closure panel 72 by respective fold lines 86, 88 and to the upper edges of respective ones of the side wall panels 32, 36 by means of further respective fold lines 90, 92. The side closure panels 82, 84 are substantially square in shape and each is divided into a first. triangular portion 94 and a second triangular portion 96 by means of a fold hne 98 extending substantially diagonally upwardly and outwardly from the intersection of its respective side wall panel 32, 36 and the front wall panel 34. The first portion 94 is adjacent and connected with the end closure panel 72 and the second section 96 is adjacent and foldably connected with the respective side panel 34, 36. A top end closure tab 100 is foldably connected with an upper edge of the rear wall panel 38 by means of transverse fold line 102.

Directional terms such as "upper" and "lower", top" and "bottom" are used herein to refer to the packaging assembly 10 in general. the outer sleeve 12 and the Hank 30 from which the skeve is made, in relation to the package and sleeve oriented in a generally upnght configuration as illustrated in Figure 1. It will be appreciated however that. the packaging assembly 10 can be used or held in different orientations and that in particular that blank 30 for the sleeve 12 can be assembled in any suitable orientation. It will also be appreciated that the designation "front" and "rear" in relation to the major panels of the sleeve is not intended to he limiting and that the panel designated as the front panel could be used to form the rear of the sleeve and vice versa.

In order to erect the blank 30 into the sleeve 12, the fold over flaps 52. 54, 56.

58 are folded inwardly about their respective fold lines 60, 62, 64, 66 and secured to the inner surface of their respective panel using the adhesive 68. This ensures there are no cut or exposed raw edges at the base of the sleeve.

A ribbon is inserted through the slot 76 and secured in position and the cover panel 78 folded over so as to cover the inner surface of the end closure panel 76 and the ribbon attachment. The blank is folded about longitudinal fold hnes 42, 44, 46 and 48 so that the wall panels 32, 34. 36, 38 assume the position of the front, rear, and side walls defining a rectangular tube and the glue tab 40 is secured to the inner IS surface of the first side wall pand 32.

To form the upper end closure 70, the side closure panels 82, 84 are pressed inwarWy along the diagonal fold lines 98 and the end closure panel 72 is folded downwardly about fold line 74 causing the first part 94 of each side closure panel to fold down on top of its respective second part 96. To secure the upper closure, the tab 100 is inserted between the folded side closure panels 82. 84 and the cover panel 78.

It will be noted that there are no exposed cut or raw edges on the upper closure.

The inner package 14 has a main body 108 defining a number of containers 110, 112, 114, 116, at least some of the containers are movable relative to each other between a closed configuration in which the inner package can be received in the outer sleeve 12 and an open configuration in which the product pieces can be seem and/or removed from their respective containers.

In an embodiment, the inner package has four containers 110, 112, 114, 116, each container having a front wall 120, a rear wall 122, opposed side walls 124, 126 interconnecting the front and rear walls, and end closures 128, 130 to define an interior volume. Located inside each container is a fitment 132 have a mounting arrangement including number of seats 134 for receiving individual product pieces 118. The seats 134 are spaced apart and aligned in a longitudinal row approximately centrally of the container. The front wall 120 of each container has an aperture 136 through which all the product pieces 118 hdd in the fitnient 132 can he seen and through which the product pieces may be individually removed.

Two of the containers 112, 114, which will be referred to as "innermost containers", are non-movably attached to one another side by side so that their front.

IS walls 121) are substantially ahgned in a common plane. The other containers 110, 116, refelTed to as "outermost containers", arc each pivotally connected with the outer side of a respective one of the innermost containers 112. 114 by means of a hinge 137. The outermost containers can each he moved from an open configuration in which they are aligned side-by-side with their respective innermost containers 112. 114 with their front face 120 exposed and positionable substantially in the common plane with the front faces 120 of the innermost containers, and a closed position in which they overlie their respective innermost containers front face to front face.

When the two outermost containers 110, 116 are both in the open configuration, all four containers are aligned in a side-by-side array with their front.

faces exposed as illustrated in Figures 5 and 6. In this configuration all the product pieces 118 can be seen and product pieces can be individually removed from any of the containers through their respective apertures 136. The front faces 120 of all the containers can be substantially aligned in a common plane, though the outermost containers 110. 116 may tend to naturally adopt a position slightly inclined to the inner package containers 112, 114 depending on the nature ol the pivotal connection.

When the two outermost containers 110, 116 are both in the closed configuration as shown in Figure 4, the front faces 120 of all the containers are hidden so that none of the product pieces can he seen or removed.

In the present embodiment, the containers 110, 112. 114. 116 are rectangular prisms and are all the same size and shape, each having a cross sectional area corresponding generally to one quarter of the internal cross sectional area of the outer IS sleeve 12. Accordingly, when the inner package 14 is in its closed configuration, it forms a rectangular block which is a snug fit inside the outer sleeve 12. lii the embodiment as shown, the inner package 14 is slightly longer than the outer sleeve 12 so that a portion 138 of the outer container projects out of the lower end of the sleeve 12. This enables the container to be easily removed from the sleeve by grasping the exposed lower end 138 and pulling the sleeve 12 off using the ribbon 77.

The main body 108 of the inner package can be formed from any suitable materials and by any suitable means. However, in an advantageous embodiment the main body 108 is formed in two identical parts 108A, l08B which are connected 1 I together. The two parts 108A, 108B are identical to one another and each includes one of the innermost containers 112, 114 and one of the outermost containers 110, 116 pivotally connected to the each other by hinge 137. Each part IOSA, IOSB is formed from a singic blank 140 of foldablc matcral as shown in Figurc 7. Thc two parts 1 USA. I OSB may he fixed together by any suitable arrangements and could he bonded togcther using an adhesive, for example. However, in an embodiment the two parts 1OSA. lUSh are fixed together using a mechanical interconnection without any adhesive.

The blank 140 is made of a cartonboard, cardboard, or a similar relatively stiff but foldable material. The blank 140 comprises two portions, a first portion 140A for producing an innermost container 112, 114 and a second portion 140B for producing the outermost container 110. 116. The two portions 140A. 140B are foldably interconnected along a fold fine 142 which forms a pivotal hinge connection 137 bctwccn thc two containcrs whcn thc blank is crcctcd.

IS The first blank portion 140A includes, from right to left as shown, a glue tab 144, a front wall panel 146 with apcrturc 136, a first sidc wall panel 148, a rcar wall panel 150 and a second side wall panel 152 separated by respective longitudinal fold lines 154, 156, 158, 160 to lorm the front, rear and side walls ol the innermost container when erected. End closures flaps 162 arc connected with the ends of the front wall panel 146 by fold lines 164. Each flap 162 has a main closure portion 162A which closes the end of the container when erected and an insert tab portion 162B separate from the main closure portion 162A by a fold line 165. A pair of end closure tabs 166 are connected with the opposed ends of the second side wall panel 152 by respective lateral fold lines 168. A locking tab 170 is connected to one end of the first side wall panel 148 by means of a lateral fold line 172.

The second blank portion 140B is substantially a minor image of the first blank portion 140A awl the conesponding parts will be designated using the same rcfcrcncc numbers but with the addition of a dash (). Thus the front wall pancl in thc second blank portion 140B will be designated 146' for example. The second blank portion 140B differs from the first in that it is not provided with a locking tab 170 hut rather has a second pair of end closure tabs 174' connected to respective ends of the second side wall panel 152' by fold lines 176'.

To erect the blank 140. it is folded along fold lines 154. 156. 158 and 160 to place the front, rear and side wall panels 146, 150, 148, 152 of the first blank portion 140A into the correct positions to form the front, rear and side walls of the innermost container portion and the glue tab 144 is adhered to an inner surface of the second side wall panel 152. The second blank portion 140B is similarly folded along longitudinal fold lines 154', 156', 158' and 160' and the glue tab 144' adhered to the inner surface of thc second side wall panel 152' to form the walls of the outermost container.

The erected blank fornis one part 108A, 108B of the body 108 of the inner package 14. A further blank 140 is erected in the same manner to form the other pail 108A, 108B of the body 108 of the inner package 14. Fitments 132 are inserted into each of the containers 110,112,114, 116 and the innermostcontainers 112, 114 of the two parts 108A 108B are mechanically connected together at both ends. The end closures for the containers arc formed in the usual manner by folding over the end closure tabs 168, 168', 174', then folding over the end closure flaps 162, 162' and inserting the tab portions 162B. 162B' in t.o the end of the container. Once the inner package 14 has been formed, products can he inserted into the seats 134 in the fitment 132 though the apertures 136 in the front face 120 of the containers. The inner package 14 is then placed in its closed configuration and can he inserted into the outer sleeve 12. The inner package 14 may be enclosed in a wrapper prior to insertion in the sleeve 12 for further protection of the product pieces.

In an advantageous method of assembly. blanks 140 for forming the inner package 14 are partly erected so that the glue tabs 144, 144' are bonded to their respective second side wall panels 152, 152' and are then flattened for transport in a flattened condition for packaging. When required for packaging, two of the blanks are taken and manipulated or popped into shape so that the front, rear and side walls of the containers adopt their desired positions. The two semi-erected parts 108A, lOB are then positioned next to each other with the containers arranged in the closed configuration with the two innermost containers positioned side by side and the assembly is inserted into a rectangular jig 180 which holds the containers vertically upright as illustrated in figures 8 to 9. The jig 180 comprises a rectangular sleeve which is open at either end and can be stably supported on a surface in the upright position. As previously noted, one of the parts lOSA, 1OSB is inverted relative to the other so that there is a locking tab 170 at either end.

Whilst held in the jig, a fitment 132 is inserted into each container and the exposed upper ends of the innermost containers are mech2mically linked together using a locking insert 182 into which the tab 170 is inserted as shown in Figures 9 and 10. The end closures for the innermost containers 112, 114 at the exposed end are formed by folding over the tabs 168 and then folding the end closure flaps 162 and inserting the tab portion 162B. The closure flap 162 covers the locking insert 182 and the locking tab 170 to secure them in position. The end closures for the outermost containcrs 110, 116 at thc exposed upper cnd are similarly formed by folding over the tabs 168', 174'. then folding over the end closure flaps 162' and inserting the tab portions 162B'.

The jig 180 is then inverted so that the other ends of the containers 110, 112, 114, 116 are exposed. The steps of locking together the innermost containers 112, 114 using the locking insert 182 and forming the end closures as described above is then repeated at the second end. The inner package 14 is removed from the jig 180 and opened out so that the product pieces 118 can he inserted into the seats 134 in the fitments 132. The inner package is then placed in its closed configuration for insertion into the outer sleeve 12 and may he wrapped. If desired, the fitments 132 can be insert into the compartments after the first cnd closures have been formed and the jig has been inverted.

The locking insert 182 is a channel or U-shaped componcnt having a planar end face 184 and a pair of inwardly directed edge walls 186. The width X end face 184 is substantially the same as the depth ol the innermost containers 112, 114 and the edge walls 183 have a recess 188 at their centre into which the adjacent side walls 124 of the two innermost containers 112, 114 can locate so that the edge walls 186 can be inserted into the open ends of the adjacent innermost containers to lock them together.

The end face has a lateral slot 190 at is centre through which the locking tab 170 on one of the innermost containers is inserted. In use as illustrated in Figures 9 and 10, the locking tab 170 is inserted through the lateral slot 190 and the edge walls inserted between the front and rear faces of the innermost containers with the adjacent side walls 124 of the innermost containers locate in the recesses 188 and the tab 170 is folded over to one side. This locks the two innermost containers together. The locking insert extcnds over approximately half the width of each of the innermost containers and is held in place by the end closure flaps 162, when the end closures for the innermost containers are formed.

The locking insert 182 can be formed form any suitable material hut is advantageously formed from a blank 192 of a relatively stiff but foldable material such as cartonboard or cardboard of the like.

Whilst in the present embodiment the parts 108A. 108B of the inner package body each only have one locking tab 170 at one end of the first side wall panel 148.

Locking tabs 170 could he provided at both ends of the first side wall panel 148 so that the parts can be used either way up. In this case, the two locking tabs 170 at each end will both be inserted through the slot 190 in the locking insert and folded in IS opposite directions.

It will be appreciated that not all of the various steps in assembling and loading the inner package 14 need he carried out in the precise order described above.

For example, the product pieces 118 could be inserted into the fitments 132 before they are placed in the containers. Similarly, the fitments 132 could he inserted into the containers before the end closures arc formed at the first end of the containers.

A Iirst 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.

On either side of the channel portion 196 are a pair of resilient side flaps 202, 204. 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. When the fitment 132 is inserted into a container 110. 112. 114, 116. 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. The inner ends of the side walls 200 of the channel portion 196 where they are connected with the first flap 202 at fold line 206 and the free ends of the second flaps 204 engage with the rear wall 122 of the container in use, as can be seen in Figure 8.

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 21 4A 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 arc 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 ll8A 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 (shape memory) biases the flaps 214 back towards the initial rest position so that they resiliently engage with the opposing side faces 118W uSC 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 arid 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.
