Description
Packaging Material, Package and Packaging Blank Field of the Invention The present invention relates to packaging materials, packages and packaging blanks.
Background to the Invention Lenticular print and holographic techniques are well known ways of producing an image that has viewing angle dependent properties. However, to date the use of angle dependent viewing properties in the field of packaging for consumer goods has been limited. Effective ways of maximising the impact of viewing angle dependent image properties in packaging for consumer goods are needed to take advantage of the visually striking appearance that packages having viewing angle dependent image properties can produce.
It is an aim of example embodiments of the present invention to address at least one disadvantage of the prior art, whether identified herein or otherwise.
Summary of the Invention According to the present invention there are provided packaging materials, packages and packaging blanks as set forth in the appended claims. Other example features will be apparent from the dependent claims, and the description which follows.
In one example embodiment there is provided packaging material in the form of a flexible sheet carrying imaging features for producing viewing angle dependent image there-on, wherein when viewed from a first viewing angle the imaging features are generally transparent, and wherein when viewed from a second viewing angle the imaging features produce an image which is not transparent.
The imaging features may be arranged to produce a three dimensional image when viewed from the second viewing angle, for example as holographic imaging features and/or lenticular imaging features such as a one dimensional array or a two dimensional array of micro lenses or other micro-optical features.
The flexible sheet material may comprise a generally transparent sheet. In another embodiment the flexible sheet may comprise a window over which the imaging features are provided, for example as an overlay. The window may comprise a transparent portion of the flexible sheet, or an opening in the flexible sheet.

Description of Example Embodiments Figure 1 shows packaging material formed into a packaging blank 10. The packaging blank 10 is shown in Figure 2 formed around a product (not shown) to produce a package 20.
The packaging blank 10 comprises a flexible sheet carrying imaging features there-on.
The imaging features are provided in separate first and second regions 21, 22 on the packaging blank 10, with the imaging features on the packaging blank 10 in these two regions referred to as the first imaging features 11 and the second imaging features 12 respectively.
The first region 21 is shown hatched, and the second region is that between the dashed lines.
The first and second imaging features 11, 12 are each arranged to produce viewing angle dependent images when observed by the human eye.
The first imaging features 11 are arranged such that when viewed from a first viewing angle the first imaging features 11 are generally transparent, and wherein when viewed from a second viewing angle the first imaging features 11 produce an image which is not transparent.
Herein, "transparency" describes the ability to pass light from the visible spectrum there-through without diffusion or significant distortion, enabling a clear and recognisable image to be formed by light passing from one side of the packaging to the other. It should be understood that the term also includes clear, but colour-filtering transparencies. Furthermore, the non-transparent images described herein may comprise real or virtual images which at least partially obstruct, overlie, augment or otherwise alter the image which would be visible when observed from the first viewing angle or which would be visible if the imaging features were not present.
The first imaging features 11 are arranged to produce a three dimensional image when viewed from the second viewing angle, as may suitably be achieved by using a two-dimensional array of micro-optical features on the packaging blank 10. In the region of the first imaging features 11 the flexible sheet which carries the first imaging features is itself generally transparent, meaning that when viewed from the first viewing angle the product which is contained in the package 20 is visible through the packaging blank 10 when formed into the package 20, thus enabling a prospective purchaser to inspect the product an appreciate its characteristics and qualities by looking through the packaging blank 10.
However, by changing the angle from which the package 20 is viewed, the non-transparent image produced by the first imaging 11 features becomes visible. In the example embodiment shown, the first imaging features 11 are arranged when viewed from the second viewing angle to produce an image including information about the product contained in the package 20, for example a brand identifier, or a description of the product's features or characteristics.
The second imaging features 12 are arranged on the packaging blank 10 such that when the packaging blank 10 is formed around a product by wrapping to form the package 20, the second imaging features 12 are position on the front face 21 of the package 20 and run from the front face 23 around the edges of the front face 23 and onto the side and end faces 24, 25 of the package 20. In this way the second imaging features 12 are provided on non-planar portions of the package 20.
As mentioned above, the second imaging features 12 are arranged to produce viewing angle dependent images when observed by the human eye. Consider the packaging 20 as stationary, and viewed by an observer moving relative to the packaging 20 such as walking past the packaging 20 when displayed on a supermarket shelf. It will be appreciated that the non-planar arrangement of the second imaging features 12 means that the change in viewing angle produced as the observer moves relative to the packaging will be different across the extent of the second imaging features 12. This increases the likelihood of the observer appreciating a transition between viewing angle dependent images provided by the second imaging features 12. Furthermore, the different relative orientations of the second imaging features 12 provided across the second region 22 mean that relative to the observer's movement, different types of transition between first and second viewing angles and therefore different viewing-angle dependent images may be provided by the second imaging features 12.
The second imaging features 12 are arranged such that viewed from a first viewing angle the first imaging features 12 produce a first virtual image, and when viewed from a second viewing angle produce a second virtual image. The images produced by the second imaging features are produced by a two-dimensional array of micro-optical features provided on the on the packaging blank 10 which is formed around a product to produce the package 20. The micro-optical features may comprise micro lenses, or specular reflection features for example.
In the example embodiment shown in Figures 1 and 2, the packaging material may comprises a laminated material of a plurality of layers, with the imaging features 11, 12 provided on a surface layer, or overlaid by only transparent layers. Suitable laminations comprise one or more plastics sheet and one or more metallic foil sheets, for example bonded to one another using an adhesive, with the foil sheet for example providing a base for the plastics. An advantage of this type of lamination is that transparent plastics layers may conveniently be used, or transparent windows over which the imaging features may be provided, for example as an overlay. The laminated material may in some embodiments conveniently be provided with a cold seal adhesive base layer, enabling a re-sealable package to be formed using a flow wrap process. The cold seal adhesive base layer may for example provide a seal when pressed against itself, or against another surface of the packaging material during packaging. The packaging material may be overlaid by a layer of release lacquer, which is provided to facilitate opening of packages, for example flow-wrapped packages made using the material. The use of a release lacquer may be particularly advantageous when cold seal or other adhesive layer is provided in the packaging material.
In other embodiments the imaging features 11, 12 may be provided on a separate label, for example to be bonded to the packaging blank during the packaging process by use of adhesive. In still other embodiments the imaging features 11, 12 may be formed on a label which is in-moulded to a substrate material. In-mould labelling is a process which a label is positioned in a mould and the substrate formed into its desired shape using the mould. This results in the moulded form including the label therein, giving benefits in the manufacture of moulded plastics containers such as bottles and tubs. Figure 5 shows an example package 50 with an in-moulded label 52 in the lid 54, the label 52 carrying imaging 51 features to provide a three dimensional representation of the cheese product contained in the package 50.
As shown in Figure 2, the imaging features are provided on a non-planar portion of the package 20 as the flexible sheet material of the packaging blank bends around the edge of the front face 23 of the package 20. However, it will be appreciated that many other variations are possible, depending on the shape of the product to be packaged and the desired characteristics of the images to be produced by the imaging features. For example the imaging features may be provided on a convex portion of the package that conforms to a curved face or other feature of the shape of the packaged product. The imaging features may also be provided at a concave portion of the package, for example by vacuum forming around concave portion of the product. Even though curvature and different angles of the surface or surfaces carrying may be thought to generally distort the image that would be produced by a perfectly flat arrangement of imaging features, some example embodiments may exploit this distortion to produce eye-catching visual effects. In such embodiments the imaging features are designed to produce a pre-determined imaging effect on a flat planar surface, but in the packages of the example embodiments the imaging features are provided across the non-planar surface. In example embodiments, packaging comprising the flexible sheet material may be displayed for sale on a shelf, display stand, rack, hanger or the like, in such a way as to maintain portions of a first face and a second face visible to consumers as they move by package. Packaging in which imaging features are provided on first and second faces enable two different effective viewing angles for the imaging features provided on the two faces, which may increase the appealing effect of the images produced by the imaging features.
Furthermore, interesting and appealing effects may be produced by the imaging features which extend around the packaging in the area of transition from one face to another. Even if passing around the corner or edge of the packaging causes a variation in an image effect produced by the imaging features, an area of transition between images produced by features on a first face and on a second face is likely to be eve-catching, as the transitional area will produce a range of effective viewing angles as a consumer moves by the package.
Figure 3 shows a package 30 according to another example embodiment. The package 30 contains a product 301 therein, which is shown as a chocolate bar with blocks 300 having valley-like recesses 310 between them, when viewed from the side. The package 30 carries imaging features 31 arranged to produce a three dimensional image there-on, wherein when viewed the imaging features 31 provide the appearance of the three dimensional product 301 in the package so as to give the appearance of a transparent package.
The imaging features 31 and product 301 in the package 39 are arranged with one another so that the appearance of the product 301 in the package is aligned, and so that the three dimensional representation of the portions of a product 301 that are within the package correspond to a life size representation of the product in the package, including corresponding depth of valley 310.
As shown in Figure 3, the imaging features 31 are provided over only a portion of the package, but it will be appreciated that other arrangements are possible. In the Figure 3 embodiment, and other related embodiments the imaging features 31 are arranged to give the appearance of a window through the package 39 directly to the product there-within. To generate a striking visual effect the window, or the whole package frontage may be arranged with imaging features to provide a realistic, for example colour-matched, representation of the product with sufficient definition to pass as the product or to give an accurate-to-life representation thereof.
Figure 4 shows a package 40 according to another example embodiment. The package 40 contains a product 400 which is visible through a transparent portion 42.
On the transparent portion 42 are imaging features 41 arranged to produce a three dimensional image overlaid on the product 400 contained in the package. In this example the product 400 is a chocolate bar and the image produced by the imaging features 41 is a brand identifier "Milka".
In this embodiment the overlay is arranged such that the three dimensional image appears to lie directly on the product contained in the package, for example as integrated into the product.
In other embodiments the overlay is arranged such that the three dimensional image appears to extend directly out from the volume of, or sink into the volume of the product contained in the package.
Figure 6 shows a package 60 according to another example embodiment. The package 60 has a first area 61 carrying first imaging features arranged to produce viewing angle dependent images there-on across a predetermined viewing angle range, and second area 62 distinct from the first and carrying second imaging features and arranged to produce a three dimensional image across the predetermined viewing angle range.
The first imaging features are arranged to provide no visible image over a portion of the viewing angle range, for example around 30 degrees and 50 degrees. The first imaging features are arranged to provide a first image over a first portion of the viewing angle range, a second image over a second portion of the viewing angle range and a third image over a third portion of the viewing angle range. In the embodiment of Figure 6, the first portion of the viewing angle range is around 20 degrees, the second portion of the viewing angle range is around 40 degrees and the third potion of the viewing angle range is about 60 degrees. The The three dimensional image in the second area 62 is a brand identifier "Milka". The images produced by the imaging features in the first area 61 are graphical representations associated with the product, for example, mountains, a cow and an image of the chocolate product itself. In this embodiment potential purchasers moving past the package 60 have their attention caught by the images in the first and second areas 61, 62, with the contrast between the changing image produced by substitution of three dimensional images in the first area viewing angle and the three dimensional image which remains in the second area being particularly visually interesting. The package 60 also includes a printed area 63 carrying regular two dimensional print.
Figure 7 shows a package 70 according to another example embodiment in plan view.
The package 70 comprises packaging material in the form of a flexible sheet carrying a first set of imaging features 71. The first set of imaging features 71 is shown in the first part of Figure 7. The first set of imaging features 71 is arranged to produce, when viewed through a corresponding optical modifier 73 including a second set of imaging features 72, a three dimensional image. The optical modifier 73 and its effect on the appearance of the package 70 are illustrated in the second part of Figure 7.
The package 70 is provided with the optical modifier 73 packaged therein with the product, so as to be available once the packaging 70 has been opened. The three dimensional image may correspond to the appearance of the product contained in the package, or may in other embodiments correspond to a product description, or a brand or other product identifier, either in graphical or written form, or to a promotional code or similar to be made available to the purchaser of the product without being generally visible outside the package 70 unless the viewer has the optical modifier 73. In example embodiments the first set of imaging features 71 is configured such that no meaningful image information is appreciable without use of the second set of imaging features 72 from the optical modifier 73.
In one example of this type, the first set of imaging features 71 is imperceptible to the naked eye, so blending into the background of any substrate or printing which is present on the packaging material. In this example the optical modifier 73 may be passed over the packaging by a consumer in order to hunt for and/or reveal the secret image produced by the first set of imaging features 71 when viewed in combination with the second set of imaging features 72 of the optical modifier 73. In another example embodiment the first set of imaging features 71 is provided in an area that is distinctive from the remainder of the packaging, for example an area comprising a substrate or printing that has a random, pseudo random or otherwise meaningless appearance when viewed without the second set of imaging features 72 of the optical modifier 73. In this example the optical modifier 73 may be used directly to reveal a three dimensional image.
It can be seen that packages in accordance with example embodiments of the invention provide simple and cost effective ways of taking advantage of the visually striking appearance that images having viewing angle dependent image properties can produce.
Imaging features as described enable example embodiments to provide more information relating to the product within the package on the same packaged area. This enables such product packages to be more interesting and more informative to the consumer, using viewing-angle dependent images. The viewing-angle dependent images may be layered with one another to convey information in a portion of the surface area of the package. Alternatively, or in addition, the visually striking appearance of packages according to example embodiments can cause such packages to stand out from the background of other products on the shelf in a supermarket environment, with passing consumers drawing to the visual effects produced as they move past the packages, changing the effective viewing angle, and causing different angle-dependent images to bring the packaging to life.
It will be appreciated that the different types of imaging features operate to produce angle dependent images in different ways, and over different ranges of inclination and azimuth angle. The example of reflective holographic elements and micro lens arrays are envisaged as suitable for the imaging features, but others are possible.
The packaging materials, packaging blanks and packages described above can be applied to the packaging of any suitable products but are particularly suitable for use with consumable products, including confectionery products such as chocolate.
Although example embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made without departing from the scope of the invention as defined in the claims.

Description of Example Embodiments Figure 1 shows packaging material formed into a packaging blank 10. The packaging blank 10 is shown in Figure 2 formed around a product (not shown) to produce a package 20.
The packaging blank 10 comprises a flexible sheet carrying imaging features there-on.
The imaging features are provided in separate first and second regions 21, 22 on the packaging blank 10, with the imaging features on the packaging blank 10 in these two regions referred to as the first imaging features 11 and the second imaging features 12 respectively.
The first region 21 is shown hatched, and the second region is that between the dashed lines.
The first and second imaging features 11, 12 are each arranged to produce viewing angle dependent images when observed by the human eye.
The first imaging features 11 are arranged such that when viewed from a first viewing angle the first imaging features 11 are generally transparent, and wherein when viewed from a second viewing angle the first imaging features 11 produce an image which is not transparent.
Herein, "transparency" describes the ability to pass light from the visible spectrum there-through without diffusion or significant distortion, enabling a clear and recognisable image to be formed by light passing from one side of the packaging to the other. It should be understood that the term also includes clear, but colour-filtering transparencies. Furthermore, the non-transparent images described herein may comprise real or virtual images which at least partially obstruct, overlie, augment or otherwise alter the image which would be visible when observed from the first viewing angle or which would be visible if the imaging features were not present.
The first imaging features 11 are arranged to produce a three dimensional image when viewed from the second viewing angle, as may suitably be achieved by using a two-dimensional array of micro-optical features on the packaging blank 10. In the region of the first imaging features 11 the flexible sheet which carries the first imaging features is itself generally transparent, meaning that when viewed from the first viewing angle the product which is contained in the package 20 is visible through the packaging blank 10 when formed into the package 20, thus enabling a prospective purchaser to inspect the product an appreciate its characteristics and qualities by looking through the packaging blank 10.
However, by changing the angle from which the package 20 is viewed, the non-transparent image produced by the first imaging 11 features becomes visible. In the example embodiment shown, the first imaging features 11 are arranged when viewed from the second viewing angle to produce an image including information about the product contained in the package 20, for example a brand identifier, or a description of the product's features or characteristics.
The second imaging features 12 are arranged on the packaging blank 10 such that when the packaging blank 10 is formed around a product by wrapping to form the package 20, the second imaging features 12 are position on the front face 21 of the package 20 and run from the front face 23 around the edges of the front face 23 and onto the side and end faces 24, 25 of the package 20. In this way the second imaging features 12 are provided on non-planar portions of the package 20.
As mentioned above, the second imaging features 12 are arranged to produce viewing angle dependent images when observed by the human eye. Consider the packaging 20 as stationary, and viewed by an observer moving relative to the packaging 20 such as walking past the packaging 20 when displayed on a supermarket shelf. It will be appreciated that the non-planar arrangement of the second imaging features 12 means that the change in viewing angle produced as the observer moves relative to the packaging will be different across the extent of the second imaging features 12. This increases the likelihood of the observer appreciating a transition between viewing angle dependent images provided by the second imaging features 12. Furthermore, the different relative orientations of the second imaging features 12 provided across the second region 22 mean that relative to the observer's movement, different types of transition between first and second viewing angles and therefore different viewing-angle dependent images may be provided by the second imaging features 12.
The second imaging features 12 are arranged such that viewed from a first viewing angle the first imaging features 12 produce a first virtual image, and when viewed from a second viewing angle produce a second virtual image. The images produced by the second imaging features are produced by a two-dimensional array of micro-optical features provided on the on the packaging blank 10 which is formed around a product to produce the package 20. The micro-optical features may comprise micro lenses, or specular reflection features for example.
In the example embodiment shown in Figures 1 and 2, the packaging material may comprises a laminated material of a plurality of layers, with the imaging features 11, 12 provided on a surface layer, or overlaid by only transparent layers. Suitable laminations comprise one or more plastics sheet and one or more metallic foil sheets, for example bonded to one another using an adhesive, with the foil sheet for example providing a base for the plastics. An advantage of this type of lamination is that transparent plastics layers may conveniently be used, or transparent windows over which the imaging features may be provided, for example as an overlay. The laminated material may in some embodiments conveniently be provided with a cold seal adhesive base layer, enabling a re-sealable package to be formed using a flow wrap process. The cold seal adhesive base layer may for example provide a seal when pressed against itself, or against another surface of the packaging material during packaging. The packaging material may be overlaid by a layer of release lacquer, which is provided to facilitate opening of packages, for example flow-wrapped packages made using the material. The use of a release lacquer may be particularly advantageous when cold seal or other adhesive layer is provided in the packaging material.
In other embodiments the imaging features 11, 12 may be provided on a separate label, for example to be bonded to the packaging blank during the packaging process by use of adhesive. In still other embodiments the imaging features 11, 12 may be formed on a label which is in-moulded to a substrate material. In-mould labelling is a process which a label is positioned in a mould and the substrate formed into its desired shape using the mould. This results in the moulded form including the label therein, giving benefits in the manufacture of moulded plastics containers such as bottles and tubs. Figure 5 shows an example package 50 with an in-moulded label 52 in the lid 54, the label 52 carrying imaging 51 features to provide a three dimensional representation of the cheese product contained in the package 50.
As shown in Figure 2, the imaging features are provided on a non-planar portion of the package 20 as the flexible sheet material of the packaging blank bends around the edge of the front face 23 of the package 20. However, it will be appreciated that many other variations are possible, depending on the shape of the product to be packaged and the desired characteristics of the images to be produced by the imaging features. For example the imaging features may be provided on a convex portion of the package that conforms to a curved face or other feature of the shape of the packaged product. The imaging features may also be provided at a concave portion of the package, for example by vacuum forming around concave portion of the product. Even though curvature and different angles of the surface or surfaces carrying may be thought to generally distort the image that would be produced by a perfectly flat arrangement of imaging features, some example embodiments may exploit this distortion to produce eye-catching visual effects. In such embodiments the imaging features are designed to produce a pre-determined imaging effect on a flat planar surface, but in the packages of the example embodiments the imaging features are provided across the non-planar surface. In example embodiments, packaging comprising the flexible sheet material may be displayed for sale on a shelf, display stand, rack, hanger or the like, in such a way as to maintain portions of a first face and a second face visible to consumers as they move by package. Packaging in which imaging features are provided on first and second faces enable two different effective viewing angles for the imaging features provided on the two faces, which may increase the appealing effect of the images produced by the imaging features.
Furthermore, interesting and appealing effects may be produced by the imaging features which extend around the packaging in the area of transition from one face to another. Even if passing around the corner or edge of the packaging causes a variation in an image effect produced by the imaging features, an area of transition between images produced by features on a first face and on a second face is likely to be eve-catching, as the transitional area will produce a range of effective viewing angles as a consumer moves by the package.
Figure 3 shows a package 30 according to another example embodiment. The package 30 contains a product 301 therein, which is shown as a chocolate bar with blocks 300 having valley-like recesses 310 between them, when viewed from the side. The package 30 carries imaging features 31 arranged to produce a three dimensional image there-on, wherein when viewed the imaging features 31 provide the appearance of the three dimensional product 301 in the package so as to give the appearance of a transparent package.
The imaging features 31 and product 301 in the package 39 are arranged with one another so that the appearance of the product 301 in the package is aligned, and so that the three dimensional representation of the portions of a product 301 that are within the package correspond to a life size representation of the product in the package, including corresponding depth of valley 310.
As shown in Figure 3, the imaging features 31 are provided over only a portion of the package, but it will be appreciated that other arrangements are possible. In the Figure 3 embodiment, and other related embodiments the imaging features 31 are arranged to give the appearance of a window through the package 39 directly to the product there-within. To generate a striking visual effect the window, or the whole package frontage may be arranged with imaging features to provide a realistic, for example colour-matched, representation of the product with sufficient definition to pass as the product or to give an accurate-to-life representation thereof.
Figure 4 shows a package 40 according to another example embodiment. The package 40 contains a product 400 which is visible through a transparent portion 42.
On the transparent portion 42 are imaging features 41 arranged to produce a three dimensional image overlaid on the product 400 contained in the package. In this example the product 400 is a chocolate bar and the image produced by the imaging features 41 is a brand identifier "Milka".
In this embodiment the overlay is arranged such that the three dimensional image appears to lie directly on the product contained in the package, for example as integrated into the product.
In other embodiments the overlay is arranged such that the three dimensional image appears to extend directly out from the volume of, or sink into the volume of the product contained in the package.
Figure 6 shows a package 60 according to another example embodiment. The package 60 has a first area 61 carrying first imaging features arranged to produce viewing angle dependent images there-on across a predetermined viewing angle range, and second area 62 distinct from the first and carrying second imaging features and arranged to produce a three dimensional image across the predetermined viewing angle range.
The first imaging features are arranged to provide no visible image over a portion of the viewing angle range, for example around 30 degrees and 50 degrees. The first imaging features are arranged to provide a first image over a first portion of the viewing angle range, a second image over a second portion of the viewing angle range and a third image over a third portion of the viewing angle range. In the embodiment of Figure 6, the first portion of the viewing angle range is around 20 degrees, the second portion of the viewing angle range is around 40 degrees and the third potion of the viewing angle range is about 60 degrees. The The three dimensional image in the second area 62 is a brand identifier "Milka". The images produced by the imaging features in the first area 61 are graphical representations associated with the product, for example, mountains, a cow and an image of the chocolate product itself. In this embodiment potential purchasers moving past the package 60 have their attention caught by the images in the first and second areas 61, 62, with the contrast between the changing image produced by substitution of three dimensional images in the first area viewing angle and the three dimensional image which remains in the second area being particularly visually interesting. The package 60 also includes a printed area 63 carrying regular two dimensional print.
Figure 7 shows a package 70 according to another example embodiment in plan view.
The package 70 comprises packaging material in the form of a flexible sheet carrying a first set of imaging features 71. The first set of imaging features 71 is shown in the first part of Figure 7. The first set of imaging features 71 is arranged to produce, when viewed through a corresponding optical modifier 73 including a second set of imaging features 72, a three dimensional image. The optical modifier 73 and its effect on the appearance of the package 70 are illustrated in the second part of Figure 7.
The package 70 is provided with the optical modifier 73 packaged therein with the product, so as to be available once the packaging 70 has been opened. The three dimensional image may correspond to the appearance of the product contained in the package, or may in other embodiments correspond to a product description, or a brand or other product identifier, either in graphical or written form, or to a promotional code or similar to be made available to the purchaser of the product without being generally visible outside the package 70 unless the viewer has the optical modifier 73. In example embodiments the first set of imaging features 71 is configured such that no meaningful image information is appreciable without use of the second set of imaging features 72 from the optical modifier 73.
In one example of this type, the first set of imaging features 71 is imperceptible to the naked eye, so blending into the background of any substrate or printing which is present on the packaging material. In this example the optical modifier 73 may be passed over the packaging by a consumer in order to hunt for and/or reveal the secret image produced by the first set of imaging features 71 when viewed in combination with the second set of imaging features 72 of the optical modifier 73. In another example embodiment the first set of imaging features 71 is provided in an area that is distinctive from the remainder of the packaging, for example an area comprising a substrate or printing that has a random, pseudo random or otherwise meaningless appearance when viewed without the second set of imaging features 72 of the optical modifier 73. In this example the optical modifier 73 may be used directly to reveal a three dimensional image.
It can be seen that packages in accordance with example embodiments of the invention provide simple and cost effective ways of taking advantage of the visually striking appearance that images having viewing angle dependent image properties can produce.
Imaging features as described enable example embodiments to provide more information relating to the product within the package on the same packaged area. This enables such product packages to be more interesting and more informative to the consumer, using viewing-angle dependent images. The viewing-angle dependent images may be layered with one another to convey information in a portion of the surface area of the package. Alternatively, or in addition, the visually striking appearance of packages according to example embodiments can cause such packages to stand out from the background of other products on the shelf in a supermarket environment, with passing consumers drawing to the visual effects produced as they move past the packages, changing the effective viewing angle, and causing different angle-dependent images to bring the packaging to life.
It will be appreciated that the different types of imaging features operate to produce angle dependent images in different ways, and over different ranges of inclination and azimuth angle. The example of reflective holographic elements and micro lens arrays are envisaged as suitable for the imaging features, but others are possible.
The packaging materials, packaging blanks and packages described above can be applied to the packaging of any suitable products but are particularly suitable for use with consumable products, including confectionery products such as chocolate.
Although example embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made without departing from the scope of the invention as defined in the claims.
