Description

WO 2010/128278 PCT/GB2010/000865 Packaging Technical Field of the Invention The present invention relates to packaging, and in particular but not 5 exclusively, to packaging for food and confectionery items including generally block shaped products. The present invention is also directed to a method of packaging, to methods of manufacturing a wrapper for a packaging and to a kit of parts from forming a packaging. Background to the Invention 10 It is known to package products in a flexible wrapper which is folded about the product and seams formed between overlapping edge regions of the wrapper so as to encase the product. This type of packaging is often used for packaging generally block-shaped food products, including chocolate bars and other snack type confectionery products. In order to protect the food product, the wrapper is typically 15 fabricated from a substantially gas and moisture impervious material, such as a metal foil, or a plastics material (including a laminate of either or both materials) so as to provide a hermetically sealed container for the product. Such known wrappers may be formed from a length of flat, foldable material having an inner surface directed to the food product and an outer surface. The outer 20 surface may be printed on or otherwise be provided with information for the consumer. The material is folded about the product and the longitudinal side edges are bonded together to form a longitudinal sealed seam extending the length of the product, sometimes referred to as a "fin seal" or "fin seam". The material extends beyond the ends of the product and opposing edge regions at either end of the wrapper 25 are bonded together to form transverse end seams. The seams may be formed using an adhesive to bond the opposing surfaces of the wrapper or by heating the material under pressure so that the opposing surfaces melt and fuse together to form a welded seam. Packaging of this nature can be produced using a flow-wrap method in which 30 a film of material is supplied in a roll to package a number of products in a substantially continuous process. The material is fed through a machine which folds it WO 2010/128278 PCT/GB2010/000865 2 about each product in turn so that opposing side edges are brought into contact and bonded together to form the longitudinal seam, which usually extends along a rear face of the product. The material is crimped at either end of the product to form the end seams and the material is cut to separate each package from the remainder of the 5 film. Alternatively, packaging of this nature may also be formed by envelope or sheet feeding and sealing effected by means of pressure and/or heat. The known packaging forms a fully sealed container for the product, which is substantially gas and moisture impervious and may be printed on to make the packaging attractive to customers. 10 Confectionary products such as chocolate bars are often given as gifts on special occasions or as a thank you present. In order to personalize a gift, the giver may wish to add a message but the wrappers currently used are not amenable for writing on or there may be no suitable blank area on which a message can be placed. To overcome this problem, a giver currently has the option of writing a message on a 15 gift card which can be attached to the wrapper or provided separately from the gift itself. This is not particularly convenient as it requires the giver to purchase a gift card and either find a means of attaching it to the existing packaging or run the risk of the card being separated from the gift. It is an object of the invention to provide an improved packaging which 20 overcomes or at least mitigates some or all of the above disadvantages. It is a further object of the invention to provide an improved method of packaging which overcomes or at least mitigates some or all of the above disadvantages. It is a still further object of the invention to provide a kit of parts for forming a. 25 packaging which overcomes or at least mitigates some or all of the disadvantages of the prior art.

The kit may comprise a see-through label for affixing to the 15 wrapper to form the pouch. Detailed Description of the Invention An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure I is a plan view of a packaging in accordance with a first embodiment 20 of the present invention; Figure 2 is a view similar to that of Figure 1 but showing a message card inserted into a pouch; Figure 3 is a longitudinal cross-sectional view through part of a front face region of the packaging of Figure 1 taken on line X-X; 25 Figure 4 is a plan view of a packaging in accordance with a second embodiment of the present invention, shown the packaging with a message card inserted in a pouch; Figure 5 is a plan view of a see-through label forming part of the packaging of Figure 4; and WO 2010/128278 PCT/GB2010/000865 9 Figure 6 is a plan view of a message card forming part of the packaging of Figure 4. The same reference numerals but increased by 100 in each case are used in relation to the various embodiments described below. 5 Referring initially to Figures 1 to 3, packaging in accordance with a first embodiment of the invention is indicated generally at 10. The packaging 10 comprises a wrapper 12 of flexible material which is folded around the product and sealed to fully enclose the product. Over lapping longitudinal edge regions of the wrapper 12 are bonded together to form a longitudinal fin seam 10 (not shown) which extends along a rear face of the packaging. Opposing end edge regions of the material are bonded together to form transverse sealed seams 14, 16 at either end of the product. The longitudinal fin seam and the transverse seams 14, 16 can be formed using an adhesive to bond the opposing surfaces of the wrapper or by heating the material 15 under pressure so that the opposing surfaces melt and fuse together to form a welded seam. Alternatively, an ultrasonic means of bonding the opposing surfaces together may be employed. The wrapper 12 can be made of any flexible, foldable material suitable for packaging the product concerned. Where the product is a food product, the material 20 may be substantially moisture and gas impervious so that when it is fully sealed, the packaging provides a hermetically sealed container for the product. Alternatively, the package may be vented so as to enable the food product to be stored for longer periods (for example, Turkish Delight products require venting so as to prevent microbial activity during storage). Examples of typical materials that can be used 25 include: paper based materials, one or more polymeric materials, and metallic foils. The wrapper may also be a lamination comprising layers of the same or different materials, which may include any of those mentioned above in any suitable combination. The general construction of the wrapper is largely conventional and so is not 30 described in detail. Figures 1 and 2 show a front face 18 of the packaging which is typically displayed to customers at the point of sale. The fin seal will typically be WO 2010/128278 PCT/GB2010/000865 10 positioned along the rear face of the product opposite front face and so is not shown in the illustrations. In accordance with the invention, the wrapper 12 has an externally accessible pouch or pocket 20 for receiving a message card 22. The pouch 20 is dimensioned to 5 receive the card 22 and to retain the card securely once it is inserted in the pouch. At least an outer face region of the pouch is see-through so that a message card 22 can be read whilst it is located in the pouch. In the present embodiment, the pouch 22 is located on the front face 18 of the packaging 10 but this is not essential and the pouch can be provided at any suitable location on the finished wrapper. 10 The pouch 20 provides a convenient means for securely affixing a message card 22 to a product which is packaged in a flexible wrapper in order to make an attractive gift. The card 22 may be printed on to provide a suitable design and may include a pre-printed message or legend such as "Happy Birthday" or "Thank You" and/or may have a space in which a user can add the name of the intended recipient 15 and/or a personalised message. A range of different message cards 22 may be produced. Message cards 22 may be supplied separately at the point of sale. However, in a particularly convenient arrangement a message card 22 is releasably mounted to the wrapper 12. As shown in Figure 1, for example, a message card can be releasably 20 mounted to the front face 18 of the packaging adjacent the pouch 20 where it can be easily seen at the point of sale so that customer can select a product with an appropriate message card 22. The user can subsequently remove the card 22 from the wrapper, write a message on the card 22 and insert it into the pouch 20 so that the message can be read as illustrated in Figure 2. The message card 22 can be made of 25 any suitable material, including but not limited to: paper, cardboard, fibreboard, cartonboard, or polymer based materials. Any suitable means can be used to form the pouch 20. In the present embodiment and as best seen in Figure 3, the wrapper 12 is formed from a laminated material having an inner layer or web 24 and an outer layer or web 26. The inner layer 30 24 may be a single layer of material or it may be itself be of laminated construction. For example, the inner layer may be a laminate of a metal foil, which may be an WO 2010/128278 PCT/GB2010/000865 11 aluminium foil, on one side and a plastics material on the other side. When the material is formed into the package, the metallic foil is positioned on the inside facing the product and the plastics material is on the outside. The outer layer 26 is bonded to the inner layer 24 by means of an adhesive 28 5 over the majority of its surface area. However, in a region 30 which defines the pouch 20, no adhesive is used so that the outer layer is not bonded to the inner layer. At least one of the inner and outer layers may be printed on or otherwise provided with information for the consumer. However, at least part of the outer layer in the un bonded region is see-through or transparent so that a message card 22 can be read 10 through the outer layer when inserted in the pouch. Conveniently, the outer layer 24 is formed from a transparent material but may be printed on whilst leaving at least part of the un-bonded region clear. The outer layer may also be a lamination comprising more than one layer of material. A slit or opening or a line of weakness 32 is formed in the outer layer 26 along 15 one edge of the un-bonded region to provide an opening region through which a card 22 can be inserted between the inner and outer layers as indicted by arrow A in Figure 1. Where a line of weakness is provided, this can be produced by means of scoring or by means of a line of perforations. In order to insert a message card 22, a user simply breaks the outer layer along the line of weakness. This may be done using an edge or 20 comer of the card 22 itself. The use of a line of weakness has the advantage that foreign matter cannot easily enter the pouch 20 before a user inserts a message card 22. The position of the slot or line of weakness can be varied as desired provided the card can be inserted into the pouch. The pouch 20 is shaped and dimensioned to receive the card 22. In the 25 embodiments shown, the card and pouch are generally rectangular in shape but this is not essential. The external pouch 20 is easily accessible to a user without opening the packaging. Where a message card 22 is releasably mounted to the package 10, any suitable means for mounting the card can be used provided the card 22 can be 30 removed from the wrapper 12 without causing significant damage to the wrapper 12 or the card. In the first embodiment, the card 22 is secured to the wrapper using one or WO 2010/128278 PCT/GB2010/000865 12 more spots 34 of adhesive, which may be a peelable adhesive. However, in alternative arrangements, the card 22 could be removably inserted in the pouch 20 or it could be mounted to a label which is itself fastened to the wrapper 12. The packaging 10 can be produced using a flow-wrap method in which a 5 continuous film of material having a number appropriately positioned pouches 20 disposed along its length is supplied in a roll to package products in a substantially continuous process. The material is fed through a machine which folds it about each product in turn so that opposing longitudinal edge regions are brought into contact and bonded together to form the longitudinal seam. The material is crimped at either 10 end of the product to form the transverse end seams 14, 16 and the material is cut to separate each package from the remainder of the film. A second embodiment of the invention is illustrated in Figures 4 to 6. The packaging 100 in accordance with the second embodiment is similar to the first embodiment and comprises a flexible wrapper 112 folded about the product and 15 sealed as described in relation to the first embodiment. The main differences between the second embodiment and the first is the method of forming the pouch and the method of releasably attaching a message card and these will be described further. In the second embodiment 100, the pouch 120 is formed by means of a label 140 which is affixed to the outer surface of the wrapper 112. An outer edge region 20 142 of the label is bonded to the wrapper so that an inner region 144 of the label is remains un-bonded to form a pouch between the label 140 and the wrapper 112. In the embodiment as shown, one edge 146 of the label is not bonded to the wrapper to form an opening by means of which a message card 22 can be inserted between the label and the wrapper. In the embodiment shown, the label 140 is generally rectangular in 25 shape and is affixed to the wrapper 112 along three edges. The fourth edge is left free to provide the opening into the pouch. At least part of the inner region 144 of the label is see-through so that a card 22 can be read when inserted in the pouch. In an alternative arrangement (not shown), the label 140 has an inner region 140 in which a slit or a line of weakness is provided to form an inlet opening through 30 which a message card can be inserted and the entire edge region of the label 140 surrounding the inner region is bonded to the wrapper.

WO 2010/128278 PCT/GB2010/000865 13 As shown in Figure 4, a slit 148 may be formed in the label extending inwardly from the centre of the free edge to make it easier for a message card to be inserted and removed from the pouch. Alternatively, a small cut-out or recess could be provided in the label adjacent the free edge to make it easier to insert a card 122 5 and to enable the card to be gripped for removal from the pocket. The cut-out could be semi-circular in shape as indicated by the dashed lines 149 in Figure 4. Where the label is bonded to the wrapper along all its edges, the slit 148 or cut-out 149 would be provided adjacent the inlet opening slit. Where the inlet opening is defined by means of a line of weakness, the slit 148 or cut-out 149 could also be defined by means of 10 the line of weakness. Similar arrangements can be provided in first embodiment 10 described above with the slit 148 or cut-out 149 being formed in the un-bonded region of the outer layer 26 adjacent the opening slit or line of weakness 32. The message card 122 in the second embodiment has a mounting portion 150 and a message portion 152. The mounting portion 150 and the message portion are 15 separated by means of a line of weakness 154 or by any other suitable means so that the message portion can be detached from the mounting portion by a user. The mounting portion 150 is permanently secured to the wrapper 112 or to a part of the label 140 by means of an adhesive. The message portion 152 may be releasably secured to the wrapper by means of one or more spots 156 of adhesive to prevent it 20 becoming bent or damaged prior to removal by a user. A user detaches the message portion 152 of the card from the mounting portion 150 by tearing along the line of weakness. The user can then write on the message portion 152 before inserting it into the pouch. In the embodiment shown, the mounting portion 150 is attached along one of 25 the side edges of the label which is affixed to and can be considered to be part of the wrapper in the finished packaging. This advantageous as the mounting portion stub 150 left behind when the message portion is removed is neatly located on the edge of the label. However, the mounting portion can be attached to the wrapper 112 at any suitable location. Rather than being attached to the wrapper, the mounting portion 30 could be attached to a product label which is itself attached to the wrapper. The two part message card 122 and its method of attachment can be used with a wrapper 12 as described above in relation to the first embodiment 10. Similarly, any WO 2010/128278 PCT/GB2010/000865 14 of the methods of releasably mounting a message card discussed above in relation to the first embodiment 10 can be adopted for use with the wrapper 112 and label 140 arrangement of the second embodiment 100. Packaging 100 in accordance with the second embodiment can be formed 5 using flow-wrap methods in which wrapper 112 are provided as part of a continuous film of material in a roll in the manner described above in relation to the first embodiment. Labels 140 to form the pouches 120 may be pre-applied to the material before it is formed into a roll separately from the wrapping process. Alternatively, labels 140 could be applied to the wrapper material as part of the wrapping process. In 10 one such method, labels 140 are affixed to the wrapper material in a process step before the material is folded about the products. Alternatively, a label 140 can be affixed to outer surface of each completed wrapper after it has been folded about the product. The packaging 10, 100 in accordance with the invention is particularly suited 15 for packaging generally block shaped food products such as chocolate bars or other similar confectionery products. However, the packaging 10, 100 can be adapted for packaging other products and in particular other generally block shaped products. The packaging 10, 100 can also be used to package products provided in two or more generally block shaped portions. For example, the packaging 10, 100 could be used to 20 package multiple chocolate or other confectionery bars arranged in-line or side-by side. The invention is not limited to packaging comprising a longitudinal seam or which is formed using a flow-wrap method and apparatus but can be adapted for use with any packing comprising a flexible wrapper which encases the product. For 25 example, in one alternative embodiment the packaging is formed from two sheets of flexible material positioned on opposite sides of the produced that are connected together along opposing edge portions surrounding the product. The foregoing embodiments are not intended to limit the scope of protection afforded by the claims, but rather to describe an example as to how the invention may 30 be put into practice.
