Description

FIELD OF THE INVENTION

The present invention relates to smart packaging, in particular to integrated smart packaging for beverage, especially suitable for carbonated beverage, in particular beer-integrated smart packaging.

BACKGROUND OF THE INVENTION

In general, smart packaging incorporates features that indicate or communicate product status or changes, environmental status or changes, or other information. It is a dynamic and preferably active extension of the static and passive communication function of traditional packaging, and communicates information to the consumer based on its ability to sense, detect, or record external or internal changes in the product's environment.
State of the art smart packaging systems provide health and safety of the product for the consumer and also monitor the condition of packed beverages to give information about shelf life and regarding the quality of the beverage during transport and storage. In this technique indicators and sensors are used instead of time consuming, expensive quality measurements for improving the shelf life and providing beverage safety. In smart packaging system indicators give information about product quality by surrounding conditions and head space gases of packagings, also indicators can be attached to the packaging surface or integrate to packagings which are improved for determining metabolite residue formed during storage. Temperature, microbial spoilage, packaging integrity, physical shock, freshness of the packed product can be controlled.
An example thereof is US2015307245 directed to a wine capsule that is configured to be attached to a beverage container and to provide a user with information relating to the temperature history of the beverage. The data logger includes at least one energy storage component (e.g., one or more capacitors), an energy harvester, a temperature sensor, at least one processor, at least one first memory, and at least one wireless communicator. The energy harvester harvests ambient electromagnetic energy. The wireless communicator is configured to transmit the stored information to a personal computer, a smartphone or tablet, or a dedicated reader device which is configured to communicate with and receive information from the wireless communicator.
A obvious drawback of the system of US2015307245 is clearly that such wine capsule is not suitable for being combined with other types of beverage packaging than bottles. In addition, as soon as the wine capsule is removed from the bottle, the bottle itself becomes a normal "stupid" bottle.
A more important general drawback however is that, although the above system covers the basic needs of beverage containment and quality control, it does not address the clear consumers' demand for packaging that is more advanced with respect to consumer interaction and creativity.
Thanks to the coming of inexpensive electronics and printing technology it recently became possible to create smart packaging that permit amongst others tracking of purchases, inventory control, automatic re-ordering, and assessment of tampering, packaging breeching etc. In addition, smart packaging containing lights, sound production, different types of sensors and corresponding sensory inputs, smart electronics, and interaction between humans, smart devices, vending machines, coupled with wireless communication, results in enhanced and personalized experience for the consumer. Also point of purchase personalized advertising, inducements, prizes, and a game-like environment can integrate at various psychological levels to positively reinforce brand loyalty and promote purchases.
In the above context, the smart packaging described in WO2015147995 contains electronics that can enable a user / purchaser to interact with the packaging and cause actions to happen either on the packaging itself or on a smart device like a smart phone or computer or a vending machine, or communicate or cause communication with a website where a data base might reside. For instance, a soda bottle or can or bag of chips can have the capability of being touched to a smart phone, having a code read, and the smart phone can take one or more actions based on the type of product within its proximity.
The smart packaging includes at least one battery and/or energy storage element and/or energy receiving element; an element configured to store information; an element configured to sense being touched; an element configured to display information and/or an element configured to generate light; an element configured to receive and/or transmit information; and circuitry electrically one or more elements of the packaging to one another.
An aspect that has been neglected in smart packaging as described in WO2015147995 , is to integrate smart packaging technology within the existing reality of today including today's industrial packaging processing and their application, i.e. the aspect of integrating intelligent technologies up to the level of industrial processing of for example a beverage can, and the product specifications, and raw materials involved has been neglected. Smart packaging has always been described without efficient implementation of its manufacturing in industrial processing been taken in account.
In addition, WO2015147995 does not address the functionalities specifically associated and required with the content of said packaging, i.e. carbonated beverages, in particular beer. As an example, an underlying objective is to provide for a smart packaging which can communicate time and temperature history of the carbonated beverage such as beer to ensure optimum maturation, proper aging, and to avoid misuse or mishandling. Another example of an underlying objective is to provide for a smart packaging which communicates the state of beverages within the packaging, either visually, either by illumination, either by sound, or haptic experiences, i.e. in case of carbonated beverages, such as beer, reaching ideal consumption temperature vs beverage type is communicated.
Further, smart packaging is a compelling proposition made increasingly relevant by the relentless and fast pace at which digital technologies integrate consumers' lives, and the proliferation of the Internet of Things (loT). An extensive list of applications in this sense, enabled by the smart packaging in accordance with the present invention will be provided in below description.
Another very important objective of smart packaging according to the present invention is to reduce the production cost, even to the point where it will be cost-effective to put intelligent features and communication means on an inexpensive product, and in particular on disposable products.

DETAILED DESCRIPTION OF THE INVENTION

As the world is moving increasingly into internet-of-things, smart packaging in accordance with the present invention offers an extensive range of intelligent functionalities in packaging for beverages, integrated up to the level of industrial processing, which can be used for consumer engagement and brand enhancement. It can amongst others also be used for proof of product authenticity and origin, tamper evidence and even further to source and delivery tracking and supply chain optimization.
In addition, smart packaging according to the present invention may drive down the cost of smart packaging to produce a smart and connected product to the point where it will be cost-effective to put intelligent features and communication means on an inexpensive product. Therefore, in a first embodiment, the present invention provides a smart metal, glass, paper-based, wood-based, or plastic packaging according to claim 1.
The smart packaging may be primary of secondary.
A structural component of a smart primary packaging for beverage is understood as a material component which is necessary to the packaging for functioning as a beverage container, i.e. for enabling the packaging to contain a beverage or to be transported, more specifically for functioning as a carbonated beverage container, and in particular for functioning as a beer container.
A structural component of a smart secondary packaging for beverage is understood as a material component which is necessary to the packaging for holding primary packaging for beverage.
A structural component of a smart secondary packaging for beverage is understood as being a component or material layer offering a contribution to enable the primary packaging to be transported. A component or material layer which does not offer any contribution to enable the packaging to contain a beverage or to be transported, and for example merely serves as a decorative layer or decorative layer system, such as ink or varnish, is not understood as a structural component.
Contradictory to a packaging with a printed display wherein the packaging is just a substrate for printing on and wherein the outer surface of the packaging as is with regards to constituting the display is only required to be suitable for printing the necessary layers upon, in the present invention a structural component of the packaging is an essential component of the actual sensory perceptible output and it must have the necessary material characteristics required for proper functioning of the sensory perceptible output. A component or material layer which does not offer any contribution to the proper functioning of the output, and for example merely serves as a substrate for fixing or printing the output on, is not understood as an essential component of the output. Another example is US2012/0160725 disclosing a packaging and a method according to the preambles of claims 1 and 7, respectively, where testing material changing color upon detecting contamination in the beverage is the inner surface of the beverage container's base and/or rim and/or sidewall, and wherein the base and/or rim and/or sidewall merely serves as a substrate for the testing material.
In other words, the structural component is a component which is essential for the proper functioning of the sensory perceptible output and which is inherently already present in the packaging as is before the output is fully constituted thereon. Consequently, it would not be possible to integrate at least partially the process of constituting the sensory perceptible output in the manufacturing of a packaging which misses that specific component (specific material layer) because it is necessary for the functioning of the sensory perceptible output. Both the smart packaging and the sensory perceptible output have a structural component in common, i.e. at least one necessary material layer included in the structure of the packaging, or in the structure of a part of the packaging, and not serving merely is a decorative layer serves as a necessary component of the sensory perceptible output.
Consequently, the manufacturing of the sensory perceptible output may be at least partially integrated in the manufacturing of the smart packaging, resulting in reduced material cost, reduced production time, and in general reduced production cost, even to the point where it will be cost-effective to put intelligent features and communication means on an inexpensive product, and in particular on disposable products.
In general, the present invention enables intelligent technologies to be integrated up to the level of and into industrial mass production of beverage containers.
In the context of the present invention, a sensory perceptible output may be constituted essentially by an active layer which must be at least partially activated in order to generate a sensory perceptible output. Depending on the type of active layer, it may be activated and controlled by several types of activation triggers, such as a voltage difference over the active layer, or by voltage differences over parts of the active layer, by an electromagnetic field, or by a magnetic field. Further also (locally applied) temperature changes, (locally applied) pressure variation or (locally applied) strain variation may trigger activation.
In order to generate a voltage difference over the active layer, it may be covered by at least one adjacent electrically conductive layer (e.g. an electrode, or it may be positioned in between adjacent electrically conductive layers, namely an electrically conductive bottom layer (also called the bottom electrode) and an electrically conductive top layer (also called the top electrode).
In case of activation by a magnetic field, the active layer may be activated by one or more adjacent electrically conductive layers (in some cases separated from the active layer by insulators). On top of an electrically conductive top layer, an encapsulation layer may be applied to protect the underlying layers. Further, additional components (i.e. layers) may be present such as a polarizer, a mirror, a polarized light emitter, etc. for example in case of a liquid crystal display.
A temperature change may be applied using resistive conducting tracks acting as heating elements.
Besides an electric field, a magnetic, field, an electromagnetic field, a temperature variation, pressure variation, or strain variation being generated by means internal to the smart packaging, each type of activation trigger may also be generated by means partially, or completely external to the smart packaging, for example generation means provided at the point-of-sale such as an electromagnetic field generator in the shelf of a store or in the cash register.
The active layer may be also externally activated by another packaging. The latter may be of any type of (smart) primary or secondary packaging having appropriate means to activate an active layer of a sensory perceptible output constituted in or on another primary or secondary packaging. As an example, an electromagnetic field generated by a secondary packaging may activate an output on a corresponding primary packaging, or vice versa.
In the context of the present invention, a sensory perceptible output may be any type of device integrated in the packaging enabling a user or consumer to sense any sensory perceptible status change of the packaging or the beverage. Such output may be visual output, an audio output, a haptic output, or any other output sensible by touch, taste, or smell.
More specifically, a visual output may be any device integrated in the packaging enabling an area of the container to emit light, or to change its absorption or transmission of specific wavelengths of light (e.g. colour change), under electrical, electromagnetic, or magnetic control, or triggered by pressure, strain, or temperature variation. Emitting, absorbing, or transmitting light may include showing any kind of colour signal, or presenting a graphic, a text, a logo, a video, including a brand, a label, an interactive label etc., or projecting a graphic, text, logo, etc. onto an object present in the environment.
A visual output may be for example any type of display such as amongst others Liquid Crystal Displays (LCD), Electronic Paper Displays (EPD), rigid or flexible organic light-emitting diode (OLED) displays, electrochromic displays, electroluminescent displays, electrophoretic dispays, OLED light sources, LED light sources, or any combination thereof, or any type of projector or beamer with suitable size.
A haptic output may be any device integrated in the packaging enabling at least part of the packaging to apply forces, vibrations, or motions, under electrical control, in a way that is felt by a user holding or touching the container, or in a way that the forces, vibration or motions may be transferred to other objects, for example to other bottles in the packaging or on the shelf. Such device may use for example piezoelectric materials.
An audio output may by any device integrated in the packaging enabling an area of the packaging to vibrate for transmitting an audio signal into the air, or for transducing an audio signal to other objects surrounding the packaging and allowing transmitting the audio signal in to the air. The frequency range of vibrations may include that of human hearing, as well as ultrasonic and sub-sonic frequencies. An example of an audio output may be electrostatic speakers or thin-film flexible speakers.
Other sensory perceptible outputs may be any type of devices integrated in the packaging enabling a user or consumer to sense any change of surface state of the packaging (e.g. change of roughness, static electricity), to sense a smell which is released upon activation, to sense a taste which is released upon activation, etc.
In an embodiment in accordance with the present invention, in order to generate a voltage difference, an electromagnetic field, or a magnetic field, or a temperature, pressure, or strain variation over the active layer, the smart packaging may comprise a power supply supplying power obtained from a source present on or in the smart packaging, or from a source external to the smart packaging via an energy harvesting element on or in the smart packaging. Types of power sources may be for example batteries, (super)capacitors. Types of energy harvesting elements may be antennas, kinetic or thermoelectric generators, photovoltaics (e.g. organic photovoltaics (OPV), etc.
In some embodiments, the active layer may be activated by activation triggers generated external to the smart packaging in which case the packaging does not require to have a power supply for powering the at least one sensory perceptible output.
In an embodiment in accordance with the present invention, a smart packaging may additionally comprise any type of supporting electronic systems, which may include digital logic, processing units, memory, gate arrays including programmable gate arrays, passive components, such as resistors, capacitors, inductors, analogue instrumentation, power control circuits, display driver circuits, or any combination thereof. These supporting electronic systems may be built from discrete components attached to the smart packaging substrate, connected by conductive tracks on the substrate, and/or components printed upon the substrate.
More specifically, a smart packaging in accordance with the present invention may comprise a sensory perceptible output, wherein a structural component, or a plurality of structural compounds of the packaging forms a component or a plurality of components of the at least one sensory perceptible output, and additionally a combination of a variable number of components of the following functional areas:

The metal structural component forming an electrically conductive layer may also be a component of a paper-based, wood-based or plastic-based smart packaging. A plastic bottle may comprise for example a metal ring structure in the body or the neck, or a corrugated board tray may comprise a rigidity enhancing metal layer, or a carton packaging may have an integrated metallic (cfr. Tetrapak).
The metal structural component forming an electrically conductive layer may be the metal layer of a closure of a beverage bottle, such as for example the tin plate of a glass bottle crown or the metal of the crown itself, or the aluminum layer of a Roll On Pilfer Proof cap (ROPP).

The smart packaging may flash and light up when the same brand's advertisement is being broadcast, or an ultrasonic code may trigger the display.
The smart packaging generates a visual, audio, or haptic output when something happens in an event I'm interested in, for example a goal scored of my favorite team.
Any type of sensory perceptible output may communicate "cold" in a perceived way when the liquid inside reached the appropriate drinking temperature.
A visual, audio, or haptic output may communicate an incoming message on your phone (.cfr a smart watch)
Any type of sensory perceptible output may communicate a profile match in a dating event.
At least one sensory perceptible output may communicate your taxi has arrived.
The smart packaging may have a visual output triggered to emit light making the ice in an ice bucket appear to glow, or to emit UV-light making fluorescent objects in the environment to emit light.
Via vibrations the smart packaging may create optical effects in the beer, which may be emphasized by the application of light. In particular, effects created might include the following: creating ripples on the surface of the liquid, stimulating bubbles in the beer in specific areas and/or at specific times, creating or recreating foam on the beer etc. The effect may be adapted as the level of beer in the bottle changes.

Example 1 (illustrated bv Fig 1)

A display is constituted on a metal beverage (1) can wherein the aluminum body of a beverage can forms the 'bottom' electrode, which is connected to GND on the driver circuit. The segments illustrated are individual long thin segments running from top to bottom of the can. However, they could in principle be any arbitrary shape. The segments comprise an active layer, top electrode conductive layer, insulating layers as required, and a top encapsulation layer.
Therefore:

Insulating layer areas (not shown) may be printed onto the aluminum (11), to create custom electrode shapes, or may be provided by the spray coat epoxy applied in the process immediately after fabrication of the can.
An active layer (12) is printed depending on what type of sensory perceptible output to implement. Different areas of the can may have different active layers, in order to put multiple functions on one can.
Distinct, electrically separate top conductive layer segments (13) are then printed. In the case of a display, this layer will be transparent. This could be either Indium Tin Oxide (ITO), a transparent organic conducting material, or other transparent conductor.
Both the active layer and top level conductive layer may be printed on using additional rollers on the offset printing process, which already exists to apply paint to the outside of the can.
in addition, electronic components may be attached, with electrical connections to one or more conducting layer(s) present. One of these conducting layers is the aluminum can body itself, which acts as a circuit ground or power plane.
A protective encapsulation layer (14) is then printed as the top conductive layer. This may be the same paint or lacquer as is already used to paint and/or protect the can, as already produced. Where light is required to be emitted, the top layer should be a transparent lacquer. Paint may be used to create shadow mask, as an additional optical effect.
Baking and curing of all the layers is performed in the existing baking and curing process provided to manufacture the can.

In the case of a reflective display, the metal used as ground plane may also form the mirror of the reflective display.

Example 2 (illustrated bv Fig 2)

A pixelated, light emitting display is integrated onto the outside of a glass bottle (2). This is realised by the deposition of row and column electrodes, either side of an active layer that is also deposited onto the bottle..
Therefore:

The glass (21) is embossed, patterned or shaped in such a way as to guide the light in a specific designed pattern, from a light source or multiple light sources. For example, in the conventional glass bottle manufacturing process, the molten glass is formed into a bottle by blowing it into a mould. To this mould additional patterns may be added in order to:
1. (i) Create geometries for active and conducting coating layers to be deposited by printing
  processes. e.g. 'ridges' and 'peaks' may pick up ink/paint/coating, whereas troughs won't.
2. (ii) Create features in the bottle which effect light guiding effects around the bottle
3. (iii) Create features in the bottle that enhance mechanical resonant effects, or amplify sound from a speaker element.
Laser etch/decoration may be applied when hot or indeed cold, to add additional embossed features to achieve features above.
Following forming, a 'hot end coating' is normally applied to a bottle using spray coating and/or chemical vapour deposition. The nature of the coating applied may be varied, such that the coating is conducting to form the bottom electrode layer (22). It may also be semi conducting and, by applying multiple iterations of this process, used to form part of a set of thin film transistors in the context of being an active matrix display.
The active optical layer (23), comprising any of the technologies described above is then printed.
A transparent top conducting layer (24) is then printed. This could be either Indium Tin Oxide (ITO), a transparent organic conducting material, or other transparent conductor.
The active layer and top level conductive layer may be printed on using additional rollers on the offset printing process, which already exists to apply paint to the outside of the can.
A protective encapsulation layer is then printed as the top layer. This may be the same paint or lacquer as is already used to paint and/or protect the can, as already produced. Where light is required to be emitted, the top layer should be a transparent lacquer. Paint may be used to create shadow mask, as an additional optical effect.
Baking and curing of all the layers is performed in the existing baking and curing process provided to manufacture the can.
The light sources are added to the packaging, either as printed electroluminescent or OLED light sources, or as discrete components such as conventional LEDs.

Example 3 (illustrated by Fig 3)

This example comprises a piezo-electric vibration element (31) attached to the top section of an aluminum beverage can (3).
The aluminum of the can forms the bottom electrode (32) for the piezo device. It also forms a mechanically resonant structure to amplify and distribute the sound or vibration from the piezo device to the user. The piezo layer, other electrode, and encapsulation are formed by printing or otherwise depositing the layers onto the can lid.
The following existing manufacturing process steps may be used:

The lid is stamped/punched to form in the normal manufacturing process. Features may be put into the stamp to control and implement specific resonant functions of the metal. They may also be used to create patterns into which the device layers may be deposited.
Insulating layer (not shown) between aluminum can and active layer is provided by the spray coat epoxy applied in the process immediately after fabrication of the can.
The active layer (31) and top level conductive layer (33) are printed on using additional rollers on the offset printing process, which already exists to apply paint to the outside of the can.
The top conductive layer may be added by the anodizing plating process already present to plate a metallic layer onto the lid.
The encapsulation layer (not shown) is formed by the varnish already provided in the manufacturing process.
Baking and curing of all the layers is performed in the existing baking and curing process provided to manufacture the can.

Example 4 (illustrated by Fig 4)

This example is based upon a secondary packaging made from fibre board coated with a metallised film and laminated polymer layer.
In existing packaging applications, such secondary packaging typically comprises a stack up from inside to outside as follows:

Fibre board layer as a sheet.
Metallised layer, either deposited by metallised paint or by a sheet of foil laminate
Transparent polymer layer, as a sheet, laminated upon the metallised layer
Printed paint layer
Varnish

This type of packaging material is already widely used to make packaging with a high quality visual appearance whereby the fibre board adds mechanical structure and durability, the metallised layer is used not only to create a shiny visual appearance but also for enhancing water resistance and rigidity, and the laminated polymer layer gives a smooth finish and water resistance.
Constituting a display on this packaging may be done as follows:

Fibre board layer is unchanged.
The metallized layer (41) is a conducting layer and is used as the bottom electrode for the display (45), and also as a mirror layer for a reflective display.
The transparent polymer layer (42) is functionalized by the addition of material to the polymer when it is molten, before it is formed into the sheet which is laminated into the package. The functionalization makes the sheet electro-optically active, such that it emits light (e.g. electroluminescent) or modulates existing light when appropriate field is applied.
The top level conductive layer (43) may be printed on using additional rollers or print stages on the offset printing process, which already exists to apply paint to the outside of the can. A transparent conducting material shall be used in the case of a display.
The encapsulation layer (44) is formed by the varnish already provided in the manufacturing process.
Baking and curing of all the layers is performed in the existing baking and curing process provided already for the coatings on the package.
