Definitions

• the present invention relates to a method for making a content use monitoring package and the package itself.
• the package has a removable re-usable electronic circuit board.
• Such devices broadly comprise sensor detecting/monitoring electronic tags, sensor grids printed with conductive ink, means of connecting the two and means of inserting the device in a pharmaceutical blister package.
• the pharmaceutical market wants a medication monitoring device that is:
• the present invention addresses the limitations of prior art and meets the criteria set forth herein.
• the invention contemplates in one aspect a means of attaching a sensor monitoring electronic tag to a flexible dielectric substrate on which has been printed a conductive grid so as to ensure precise and reliable electric continuity between the two. Tags so connected can then be used to monitor either digital (one trace per opening) or analog (such as resistive ladder array) printed grids.
• Such means is also reversible to allow reuse of the tag with new printed grids in new packages thereby reducing cost.
• Thin substrates are easily attached to the blister card (usually by use of self-adhesive backing), and also contribute to easy consumer use by minimizing package thickness.
• a low or zero insertion force (ZIF) flex circuit connector is used to connect the input pads of an electronic sensor monitoring tag to the output traces of a conductive grid printed on thin Mylar, food grade plastic or similar substrate. At the time of assembly the two components of the flex circuit connector are snapped together.
• ZIF zero insertion force
• Thinner conducting traces save on the cost of conductive ink, lowering package costs and reducing the cost to the environment.
• Thinner conducting traces leave more unused space on the grid for add-ons such as push buttons to record user data, reminders, LCD, LED and OLED displays, etc.
• the blister package can be disassembled and the tag separated from the grid and reused with a new grid in a new package saving considerable cost (up to 99% if re-used 100 times).
• Printing conducting traces on separate inlays removes an intricate process from the process of manufacturing the surrounding blister card paperboard, allowing separate QA of such inlays and pre-manufacturing of complete inlay assemblies (tag connected to trace inlay).
• a method of making a content use monitoring package comprising the steps of aligning a blister card having blisters on a top side with a cover having cut-outs so the blisters of the blister card are aligned with the respective cut-outs of the cover; connecting an electronic sensor monitoring tag having reusable electronic circuitry and power source to a conductive grid printed on a thin flexible substrate so the tag and grid are in electrical continuity to form a monitoring device; aligning the conductive grid with the blisters on the blister card and optionally fixing it via self-adhesive backing to the blister; obtaining a backing having cut-outs corresponding to the blister positions of the blister card and having a die-cut pull-out corresponding to the position of the tag on the monitoring device; and sealing the backing to the cover with the blister card and monitoring device sandwiched between; wherein the tag is removable by opening the pull-out and unplugging the tag from the grid.
• a content use monitoring package comprising: a blister card having blisters on a top side and having a bottom side; a cover having cut-outs aligned with the blisters of the blister card; an electronic sensor monitoring tag having re-usable electronic circuitry and power source; a conductive grid printed on a thin flexible substrate and connected to the tag so the tag and grid are in electrical continuity to form a monitoring device; and a backing having cut-outs corresponding to the blister positions of the blister card and having a die-cut pull-out corresponding to the position of the tag on the monitoring device; wherein the backing is sealed to the cover with the blister card and monitoring device sandwiched between and the conductive grid aligned with the positions of the blisters on the bottom side of the blister card; and wherein the tag is removable by opening the pull-out and unplugging the tag from the grid.
• Figure 1 shows the content use monitoring package in a disassembled state, showing each layer therein;
• Figure 2A shows printing of the conductive grid with an additive printing process, or application using vacuum metal vapour deposition technology
• Figures 2B shows printing of the conductive grid with a subtractive printing process
• Figure 3 depicts die-cutting the printed grid to create the interface with one part of the flat flex connector
• Figure 4 shows optional printed functions that can be accommodated because of the space savings resulting from the more accurate printing of the conductive grid
• Figure 5 shows the connection of tag and grid by flat flex connector
• Figure 6A shows the finished package in an open state after heat or cold sealing
• Figure 6B shows the finished package in a closed state with the unique die-cut spine
• Figure 7 shows hard wired and wireless communication of data from the package to computers, PDAs and data storage devices.
• Figure 8 shows means of recycling the tag after the package has been used.
• One embodiment of the present invention includes a content use monitoring package such as used for monitoring the taking of blister-packaged medication doses.
• the package has a removable re-usable electronic circuit board (tag) and also contains a rupturable layer imprinted with conducting and/or sensing circuitry printed thereon by additive conductive methods such as flexographic, inkjet, offset, metal vapour deposition, gravure or screen printing methods, or by subtractive or other suitable methods.
• the circuitry is no thicker than 2 microns and typically less than 0.5 micron, available from Conductive Inkjet Technology, for example.
• the circuitry is preferably printed on a tough and resilient Mylar base material. The thickness of the Mylar substrate can be varied to optimize predictable rupturing of the printed traces.
• the re-usable sensor monitoring tag contains a power source, communication interface and/or RFID wireless interface antenna, central processor, and a flat flex connector for the printed flexible conductive monitoring grid.
• the height of the device (tag attached to the grid) including any associated components should not exceed 2.5 mm to enable complete and seamless integration of the device into the consumer package.
• the package also contains an optional means of easy access to and removal of the tag after the package content has been consumed, such as a pull-tab or other mechanism to tear open the package and allow removal of the tag for re-use.
• the battery can be replaced as required, increasing the number of reuses of the tag.
• Figure 1 of the present invention shows the various layers of the package.
• the cover 10 or top layer is preferably made of Easy Seal® paperboard or similar material commonly used in the food and pharmaceutical packaging industry. This is followed by a medication blister card 12 underneath with each blister aligned with a cut-out 20 in the cover 10.
• the third layer comprises a reusable electronic sensor monitoring tag 14 connected to a conductive grid 16 printed on thin Mylar, plastic or similar substrate by a flat flex connector 26 which connection is reversible by unplugging.
• the grid 16 is rupturable and is aligned with the associated blisters and may or may not contain a self adhesive layer with removable liner.
• the fourth and bottom layer is a backing made of Easy Seal® or other paperboard die cut to form a pull-out tab 18 to tear open the used package and allow the tag 14 to be removed from the package by unplugging the connector 26.
• the tag 14 can then be reused in conjunction with a new printed grid and its battery replaced as required.
• the backing has cut-outs 21 associated with the cutouts 20 in the cover 10.
• the conductive grid can be optionally adhered to the blister card with any form of suitable self-adhesive means.
• Figure 2A shows one manner of printing the conductive grid by an additive printing process using conductive inks containing zinc, silver, aluminium, carbon or other conductive material. This can be accomplished using standard flexographic, screenprint, inkjet, offset, etc printing methods. Also shown in Figure 2B is the subtractive printing process in which the dielectric Mylar or similar substrate has been coated with a conductive substance that is subsequently removed by die-cutting or chemical etching to leave behind the conductive traces of the grid. It is also possible to produce a subtractive process by die-cutting thin flexible foils and applying them onto a dielectric surface.
• Figure 3 shows how the grid contacts for the flat flex connector are die-cut from the printed grid for precise alignment with the contacts of the flat flex connector. Precise alignment is important if numerous conductive traces are to be connected to the tag as in digital grid designs having many individual circuits.
• the flat cable wires 30 for the flat flex connector are die-cut from the grid inlay as shown in the expanded view.
• the grid inlay is also die-cut to create flat connector wires along with the blister opening pattern and to ensure a fit with the paperboard.
• FIG 4 a number of optional printed functions are shown that are made possible by the increased empty space on the grid substrate due to the decreased area required for the more accurately printed die-cut conductive traces.
• areas can be allotted to an organic LED (OLED) display 40, a printed input button 42 for users to input data to the tag (such as a self-adhesive metal dome button 43), a printed battery 44, printed humidity sensors 46, printed or applied temperature sensors 48, and a variety of communication modes 50 including Capacitive Coupled, RFID, HF, UHF, Bluetooth, GSM and NFC.
• Use of a battery printed on the grid allows for a smaller tag, further contributing to cost savings and ease of inserting the monitoring device into existing assembly processes.
• Some printed batteries can take on organic shapes, fitting themselves into available open space, rather than requiring a particular geometric area. If an OLED display 40 is provided, the cover 10 will have a window 24 to view the display ( Figure 1).
• Figure 5 shows the means of connecting the sensor monitoring tag 14 to the printed grid 16 using a two-part reversible flat flex connector 26.
• the tag 14 has a microchip 52 and protective foam 54. Other optional components include an on-board temperature sensor 56, onboard humidity sensor 58 or indicator LEDs 60.
• the tag 14 can also optionally include wired communication 62 such as a micro-B USB plug.
• Figure 6A the completed medication compliance package 68 is shown in an open state with the monitoring device (tag connected to grid) and the medication blister card hot 64 or cold 66 sealed between two layers of paperboard.
• Figure 6B shows two instances of the medication package 68 in a closed state and the location of the pull-out 70 for tag removal.
• the spine 72 is rounded by die-cutting so the printed conductive traces 74 bend smoothly across the spine 72 and are less likely to be damaged by opening and closing cycles.
• Figure 7 shows both hard wired and wireless means by which the data from the tag 14 can be transmitted to computers, PDAs, data servers or the cloud conferring great flexibility of use on the device.
• the wired communication port 62 can be used to connect for example by USB 76 to computer.
• Wireless communication means include Capacitive Coupled, RFID, HF, UHF, Bluetooth and NFC.
• Figure 8 shows removal of the tag 14 from the used package by opening the pull-tab and unplugging the flat flex connector. The tag is then recycled, refurbished if required by adding a new power source, reprogrammed if required and attached to a new conductive grid to be inserted in a new package. The grid and paperboard are disposable. Figure 8 also shows in expanded view how an event is triggered when the conductive trace is broken and the medication is pushed through the blister.
