DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The advertising beverage can of the illustrated embodiment of the current invention requires several basic functions to be implemented, principally first among these is a device activation trigger used to determine when the can, generally denoted by reference numeral 10 in FIG. 2, has been opened. Although a beverage can is illustrated any kind or type of container for any type of goods with any kind of opening seal or mechanism may be employed with the illustrated embodiments of the invention. In one embodiment, the can 10 comprises a stacked assembly 12 coupled to a pull tab 16 of the can 10. The pull tab 16 is coupled to the can 10 by a tab rivet 20 which is surrounded by an extended rivet tab 22. Coupled between to the stacked assembly 12 and the extended rivet tab 22 is one-time use actuation switch 32. The actuation switch 32 is comprised of two halves, namely an assembly half 26 and a can half 28. The assembly half 26 is permanently coupled to the stacked assembly 12 while the can half 28 is permanently coupled to the extended rivet tab 22 by means of soldering or conductive epoxy. The assembly and can halves 26, 28 are temporarily coupled together via a perforated tab tearing seam 24. A conductive path 30 comprised of light weight wire couples the stacked assembly 12 to the actuation switch 3. The conductive path 30 forms a loop which travels from the stacked assembly 12 through both halves 26, 28 of the actuation switch 32 via the center of the perforated tab tearing seam 24, and then back into the stacked assembly 12 as seen in FIG. 2. The stacked assembly 12, conductive path 30, actuation switch 32, and extended rivet tab 22 together form a resistive switch as is known in the art. Briefly, resistive switches use electrical current to detect whether a continuous electrical path exists between two points. The cost of manufacturing resistive switches is negligible as it can be implemented in standard integrated circuit manufacturing processes as is known in the art. Resistive switches help comprise an active circuit meaning that power is discharged continuously in order to determine if the switch is open or closed. Since the can 10 is made of a conductive metal (aluminum), in one embodiment the structure of the can 10 itself can be used as a means to provide the switch ‘wiring’ or replace the conductive path 30.
With the conductive path 30 in tact as depicted in FIG. 2, the stacked assembly 12 supplies a low electrical current through the actuation switch 24. When the pull tab 16 is lifted from the can 10, the actuation switch 32 tears along the perforated tab tearing seam 24 causing the actuation switch 32 to break, leaving the assembly half 26 and can half 28 coupled to the stacked assembly 12 and extended rivet tab 22 respectively. The severed actuation switch 32 interrupts the flow of electrical current through the conductive path 30 causing an open circuit to be detected by the stacked assembly 12 as discussed below. This open circuit can then be used as the device activation trigger.
In an alternative embodiment, the device activation trigger may be a plurality of magnetic switches. Magnetic switches use the proximity of a magnetic field to determine if a switch is open or closed. In this embodiment, iron additives are coupled or integrated into the can lid 10 at a plurality of locations to make the material ferrous. Additionally a permanent magnet is coupled to the pull tab 16. In this embodiment, the conductive path 30 runs from the stacked assembly 12 through the permanent magnet disposed on the pull tab 16, through at least one iron additive or secondary magnet disposed within the lid of the can 10 and then back into the stacked assembly. Alternatively, the pull tab 16 itself may be comprised of the permanent magnet. When the pull tab 16 is lifted from the can 10, the permanent magnet is lifted away from the secondary magnet severing the connection between the two magnets. The loss of contact between the two magnets stops the current flowing through the conductive path 30 which signals the stacked assembly 12 that the can 10 is open.
In yet another embodiment, a mechanical switch may be used as the device activation trigger. A mechanical switch is passive and uses the physical movement of objects to make a connection between a power source and an audio playback device. This switch is ideal from the standpoint that it uses no power until the switch is closed and when a mechanical connection is made between the power source and audio playback device. For example, when the pull tab 16 is pulled away from the can 10, a mechanical switch coupled to both the pull tab 16 and slidably coupled within the stacked assembly 12 is moved accordingly. When the mechanical switch has moved far enough, a circuit is created between a power source and an audio playback device allowing an audio message to be heard. The mechanical switch is maintained in the closed position until the audio signal emitted from the audio playback device has been completely played back to the user.
In a further embodiment, the device activation trigger is an inductive switch which detects the proximity of a device in a similar fashion to a traditional metal detector device. An inductive switch determines the presence of a metallic objects by generating an electromagnetic field and sensing changes in the field. This type of device requires continuous power dissipation in order to generate the electromagnetic field. In this embodiment, the pull tab 16 comprises a primary inductive element and the lid of the can comprises a secondary inductive element disposed directly beneath that of the primary element when the seal 18 of the can 10 is closed. The stacked assembly 12 is coupled to both the primary and secondary inductive elements independently. When the pull tab 16 is pulled away from the can 10, the primary inductive element is pulled away from the secondary inductive element causing a change in the magnetic field disposed there between. This change in magnetic field creates a corresponding change in electrical current flowing through the conductive path 30 which signals the stacked assembly 12 that the seal 18 of the can 10 is now open.
Turning now to FIG. 3, the plurality of components comprising the stacked assembly 12 may be seen. The stacked assembly 12 preferably comprises a piezoelectric speaker or resonator 14, a substrate 34, a battery 36, and a chip-on-board (COB) assembly or audio tone generator electronics 38. The components of the stacked assembly 12 are laminated together into a single unit which is sufficiently rigid and robust enough to be used as a functional part of the pull tab 16. In other words, the stacked assembly 12 may be pulled away from the can 10 in addition to the pull tab 16 in order to open up the seal 18. All of the components of the stacked assembly 12 comprise a reduced height to provide a slim, easy to open replacement for the pull tab 16.
The speaker 14 of the stacked assembly 12 is preferably a piezoelectric speaker or a piezoelectric resonator which uses an electric field to cause a thin insulating substance such as quartz to vibrate and generate acoustic sounds. These devices are extremely thin and low cost due to their simple construction. Alternatively, a wire wound speaker may be used. A wire wound speaker is well known in the art and is used in a majority of speaker applications. Briefly, a wire wound speaker uses a small magnet and coiled wire to move a membrane which produces sound. The cost of a wire wound speaker is driven by the need for both a magnet and a significant amount of copper wire to drive the speaker membrane. The thickness of the speaker 14 may be adjusted by changing the amount of coiled wire employed.
The speaker 14 of the stacked assembly 12 is disposed on top of the substrate 34 which is comprised of plastic, metal, fiberglass, or a combination thereof. The substrate 34 comprises a cavity or a hollow void in the center to allow the audio signal that is emitted from the speaker 14 to resonate for effective audio playback.
The battery 36 stores the electrical charge necessary needed to drive the speaker 14 during audio playback. The battery 36 preferably only comprises enough storage to drive the speaker 14 once so as to reduce the cost of manufacturing of the battery 36 and to reduce its overall physical profile within the stacked assembly 12. In one embodiment, the battery 36 is a chemical battery. Chemical batteries are the most widely used charge storage device. They are available in many different compositions including lithium, alkaline, nickel hydride, and others. The most preferred composition for the battery 36 is alkaline, which provides approximately 1.5V. The stacked assembly 12 may therefore comprise a plurality of at least two alkaline batteries coupled together in series within the same layer of the stacked assembly 12. The battery 36 may also comprise a voltage doubling circuit as is known in the art so as to maintain a slim profile. Newer compositions of batteries such as nickel-zinc or other non-toxic compositions now known or later devised may also be used without departing from the original spirit and scope of the invention. In another embodiment, the battery 36 may be a capacitor capable of maintaining a large energy density when fully charged.
The COB assembly or audio tone generator and electronics 38 is an integrated circuit as seen in FIG. 1 within the stacked assembly 12 that is responsible for generating an electrical audio signal which converted into audible sound waves by the speaker or resonator 14. The COB assembly 38 comprises a microcontroller and a ROM chip containing a pre-recorded or pre-programmed audio file. The audio file may be any sort of audio file desired including but not limited to advertisements, music, or the like.
The battery 36 and COB assembly 38 work in conjunction to provide constant, low electrical current running through the conductive path 30 when the seal 18 of the can 10 is closed. The conductive path 30 is shown in FIG. 1 as part of activation trigger 39, which includes any kind of mechanism or circuit element which can be used to trigger COB assembly 38 to detect an activation event, whether it be a container opening, closing or other manipulation of the container. When the pull tab 16 is lifted from the can 10, the seal 18 is opened and the conductive path 30 is severed by one of the device activation triggers discussed above. With the conductive path 30 severed, the microcontroller on the COB assembly 38 executes a pre-programmed routine that renders the pre-programmed audio file stored on the ROM chip into an electrical signal. This signal is then transmitted to the speaker 14 for conversion into an audible tone. After the audio file has been initiated by the microcontroller, it continually plays through the speaker 14 until the battery 36 expends the last of its stored charge and the COB assembly 38 powers down, thus ceasing any further audio playback through the speaker 14.
FIG. 4 is a perspective diagram of the assembly 12 of FIG. 3 mounted on or in a lid or cap 42 of a pharmaceutical, food, health and beauty, household or industrial container 40. It is to be expressly understood that the teachings of the illustrated embodiments applied to and can be extended to all types of containers or packaging now known or later devised. Thus it is to be expressly understood that the illustrated embodiments of the invention include not just a metal pull tabs, but a plastic pull tabs, metal/plastic twist offs, metal/plastic pop top, screw top caps and lids and other release or opening devices. Cap 42 includes a tearing seam 44 integrated into cap 42. Separable, tearable or rupturable seams 44 are conventional and well known to those of ordinary skill in the packaging arts. A conductive path 46 is coupled from assembly 12 through cap 42 through or across seam 44, so that when cap 42 is opened and seam 44 torn, separated or ruptured, path 46 is broken or becomes electrically discontinuous. The discontinuity is detected by assembly 12, which is then activated.
FIG. 5 is a diagram of another embodiment of the invention in which assembly 12 is disposed on or in a resealable closure 48 of a container 50 through which closure 48 a interruptible circuit path 56 is defined. There are virtually an unlimited number of ways in which circuit path 56 could be devised. One embodiment includes a conductive lead 64 from assembly 12 on the inside threading or interior compression sealing surface of cap 48. A corresponding conductive lead 62 is provided on the exterior threading or exterior compression surface of the connection portion of container 50 which mates with cap 48. These two leads 62 and 64 overlap 58 when cap 48 is disposed on container 50 and arranged in the closed configuration. The overlap 58 defines a pair of electrical contacts to establish electrical continuity. When cap 48 is opened by unscrewing or snapping off container 50, the overlap 58 is lost and electrically continuity is interrupted. This interruption is detected by assembly 12 and can be exploited in a multiplicity of ways for plurality of objects.
For example, assembly 12 comprises a clock (not shown) which may either be synchronized with the chronological time or may be a timer recording the time which has past since the last loss of continuity on container 50. The sound recording stored in assembly 12 may then audible announce the time elapsed since the last time container 50 was opened. This information is a material utility in the case that container 50 is a pharmaceutical container and drug dosage management is being performed. The user is thus reminded that he or she probably took a dosage of the drug at the time announced by assembly 12. This prevents accidental overdoses, which may have deleterious and even possibly fatal results.
Further, assembly 12 in some embodiments further comprises an RF communication module, like RFID chips, which wirelessly communicates information pertaining to container 50 and its opening or closure to other ones of a plurality of similar assemblies 12 forming a peer-to-peer network or to a local network through router 54 to computer 52. The information includes not only the event and time of opening or closure of container 50, but the expected contents of or identity of container 50 as well. Thus, among a plurality of containers 50 so equipped, drug interactions can be checked according to stored programs in memories and microprocessors included in assemblies 12 or via stored programs in memories in computer 52. Computer 52 may be communicated to the internet 60 by conventional means and thus be connected with an external network, which may include the user's physician, pharmacy or wellness provider. The user's drug compliance can then be monitored and recorded directly by an external monitoring expert system. Failure of compliance or misuse can be detected and automatic messages via computer 52 or the telephone can be initiated to remind the user to take or refrain from taking a particular course of action with respect to drug usage as determined by actual openings of the pharmaceutical containers. A message may then be communicated to assembly 12 through computer 52 or from the onboard memory of the appropriate container 50 among a plurality of containers to provide a customized message concerning the usage of the drug in the container 50. Further, all messages announced by assemblies 12 can be selectively programmed to provide the messages in a language which is native to the user on a case-by-case basis. Such monitoring is particularly useful for senior patients, whose cognitive ability to maintain reliable drug compliance usages may be impaired by age. In other words, assemblies 12 may be provided with isolated onboard or intercommunicated intelligence from other sources to interact with the user according to usage of the containers 50 as detected by assemblies 12.
It is also contemplated within the scope of the invention that containers 50 may be arranged and configured not only to allow detection of opening or closure of container 50, but also to be structured as dispensers. In other words, instead of simply a bottle with a cap, container 50 may dispense the medicaments by dosage units like a candy dispenser in which case assemblies 12 detect the dispensing of a dosage unit directly rather than by presumption. The various mechanisms whereby tablets or other dosages units of a drug or item may be effected is again virtually limitless and are well known to those with ordinary skill in the packaging arts. Regardless of the specific dispensing mechanism, the dispensing of a dosage unit occurs through the actuation of some kind of a mechanical element, which actuation can be electrically detected by assembly 12 and exploited as disclosed above.
The embodiments of the invention are further illustrated in the context of a pharmaceutical container or pill cap 66. The pill cap 66 has many feature variations. In one embodiment, a visual electronic display 68 is included or coupled to the pill cap 66 for the purpose of indicating to the patient when a medication dose is next scheduled as shown diagrammatically in FIG. 6. Display 68 may be comprised of one or more light emitting diodes (LED). The LED's may be of multiple colors to indicate status information to the patient, namely whether the pill cap 66 has been opened and a dosage dispensed, showing for example a black color, is to be dispensed at a future date, showing for example a green color, and time or is overdue for dispensing, showing for example a red color. The display may show a different color, sound an audible alarm or enter a flashing mode, for example, if opened for dispensing a dosage, which would be duplicate dosage if taken. Display 68 could also comprises an embedded liquid crystal display (LCD) capable of displaying text or graphical information to the patient. The LCD display 68 may also contain an LED backlight light source (not shown) to make viewing in low light conditions easier. The display 68 may be viewed from the top and/or in a side profile of the pill container 66 simultaneously as shown in FIG. 6 to allow the pill cap 66 to be effectively utilized in either a horizontal or vertical stacking arrangement. The display 68 may be modified to contain specific images, such as universal man/woman gender symbols or patient selected identifiers.
The illustrated embodiments also include a universal mechanism for indicating when a pill cap 66 has been removed. The mechanism is comprised of an elastomeric membrane switch 72 inset on the inside of the pill cap as depicted in FIG. 7. When the pill cap 66 is attached or coupled to the pill container body 70, the membrane switch 72 is compressed between the cap 66 and top of the pill bottle 70, forcing the membrane switch 72 to be in the closed position. When the pill bottle cap 66 is removed, the membrane switch 72 is no longer compressed between the cap 66 and pill container body 70, thus it is in the open position. An additional time delay is added in programmable circuitry (not shown) coupled to switch 72 between the opening and closing to prevent false detection of a cap removal due to cap misalignment.
In addition to the elastomeric switch 72 to provide the pill cap status, a set of pill cap adapter rings 74 is included. The adapter rings 74 are sets of keyed threads designed to mate with the various pill container bodies 70 including those with safety cap features. It is known that the safety features of different off-the-shelf pill container bodies 70 vary by manufacturer. The pill cap 66 with the combination of universal membrane switch 72 and threaded adapter rings 74 provide a method to attach to a wide variety of pill bottles 70 with a single cap design and maintain the ability to detect cap installation and removal events across the entire set of pill bottle varieties.
In one embodiment the pill cap 66 may contain a cabled programming port 76 (via USB or any other standardized or proprietary wired interface) as depicted in FIG. 8. A programming cable 78 is connected between the pill cap 66 and a personal computer or some other electronic device such as a smart phone 80 . The purpose of the connection allows the following actions to be performed: data stored on the pill cap 66 may be uploaded to a personal computer or iphone 80. This data may contain information related to the pill cap's usage patterns and battery status. Information regarding the number of times the pill cap 66 was removed and how long it was removed from the pill bottle 70 can be used to derive the frequency of use. Data may be downloaded from the personal computer or iphone 80 to the pill cap 66. The data may contain changes to the dose information including frequency of use or clock update information to circuitry (not shown) included in pill cap 66. This could be used to adjust prescription dosing mid-course. For instance, the patient's doctor can determine that based on at home vital signs or symptoms, that the dosage frequency needs modification. Power may be provided from the programming port 76 to recharge the pill cap battery (not shown). This allows a permanent battery to be installed without the requirement for patient to periodically replace the primary battery. The visual display elements (LED or LCD) may be used to display the charge level of the primary battery to warn the patient of low battery status.
In another embodiment, a wireless communications device 82 is included in pill cap 66. The communications device 82 includes a passive, near field communications device using backscatter techniques such as that provided by conventional RFID tags. In this embodiment the patient places the pill bottles 70 on or near a tag reader device 84, which detect which medications are present by interrogating the pill cap 66 through methods such as that conventionally provided by RFID readers.
Wireless battery charging of pill cap 66 using an inductive charging process can be employed. The patient sets the pill bottles 70 on a tray or mat 84 that serves as a charging station. The pill caps 66 need not be removed from the pill bottle 70 for charging to occur. Using off the shelf technology for inductive charging is possible with the integration of a spiral PCB antenna (not shown) incorporated in the cap 66. The antenna would be coupled to a battery charging circuit included in cap 66.
Cabled programming and wireless communication disclosed above may be combined into a single capability that provides both data communications and power transfer. In this embodiment, the tray or mat 84 previously used for charging also contains a wireless communications device using RF tag technology. When the patient places the pill bottle 70 on the mat 84, the data synchronization with the patient's personal computer or smart device 80 begins. Simultaneously the battery charging function begins using the inductive charging technique disclosed above.
Integration of a real time clock into the pill cap 66 is contemplated as a feature in various ones of the illustrated embodiments. The clock maintains the current local time and compares local to a downloaded pill-dispensing schedule. The real time clock is synchronized when connected via the programming port or is set with wireless programming.
An acoustic resonator 86 is included in or coupled to cap 66 for generation of audio tones. The sounds may be simple tones or speech playback. The audio tones will be generated from data stored in memory circuitry (not shown) included in the pill cap 66. This data is updated through either the wired programming port or through the wireless data transfer. When the pill cap 66 is removed, a “debouncing period” begins to prevent false detection of a removal. After a fixed period of time if the lid of pill cap 66 remains detached from bottle 70, the audio tone generation begins. The tone samples can be selected based upon patient information such as time of day, required dosage, and/or the next dose schedule.
The modularized pill cap design provides the ability to create custom decorative or marked overlays or skins 88 for pill cap 66 as depicted in FIG. 12. Since the cap 66 utilizes keyed adapter rings 74 in order to fit to multiple types of pill bottles, the basic pill cap outline is the same for all pill bottles 70 fitted with the adapter rings 74. Using the fixed outline of the pill cap 66, the decorative or marked overlays 88 may be fabricated to a single design specification. The overlays 88 allow the patient to install custom visual identifiers onto the pill cap 66 to quickly locate medication based on familiar or customized queues selected by the patient.
In another embodiment the pill bottle 70 may contain an access security device for PRN Class 2 medications. One method for access security is through the wireless communications feature disclosed above. The patient is issued a paired communications device 90 similar to a key fob. In order for the pill bottle 70 to be opened or opened without an unlawful entry being stored in the pill cap memory, the fob device 90 needs to be in proximity to the pill cap 66. When the fob device 90 and pill bottle were within communications range the pill cap LED 68 changes colors to indicate the bottle 70 is authorized to be open. A another security embodiment includes the integration of a biometric sensor 92 such as a fingerprint scanner as is conventionally used in consumer electronics devices, such as laptops. The fingerprint scanner 92 needs to be accessed by the patient's contact of an index finger, whose finger print pattern has been pre-scanned and downloaded into cap 66, in order to change the pill cap LED color and to allow authorized entry.
Many alterations and modifications may be made by those having ordinary skill in the art without departing from the spirit and scope of the invention. Therefore, it must be understood that the illustrated embodiment has been set forth only for the purposes of example and that it should not be taken as limiting the invention as defined by the following invention and its various embodiments.
Therefore, it must be understood that the illustrated embodiment has been set forth only for the purposes of example and that it should not be taken as limiting the invention as defined by the following claims. For example, notwithstanding the fact that the elements of a claim are set forth below in a certain combination, it must be expressly understood that the invention includes other combinations of fewer, more or different elements, which are disclosed in above even when not initially claimed in such combinations. A teaching that two elements are combined in a claimed combination is further to be understood as also allowing for a claimed combination in which the two elements are not combined with each other, but may be used alone or combined in other combinations. The excision of any disclosed element of the invention is explicitly contemplated as within the scope of the invention.
The words used in this specification to describe the invention and its various embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification structure, material or acts beyond the scope of the commonly defined meanings. Thus if an element can be understood in the context of this specification as including more than one meaning, then its use in a claim must be understood as being generic to all possible meanings supported by the specification and by the word itself.
The definitions of the words or elements of the following claims are, therefore, defined in this specification to include not only the combination of elements which are literally set forth, but all equivalent structure, material or acts for performing substantially the same function in substantially the same way to obtain substantially the same result. In this sense it is therefore contemplated that an equivalent substitution of two or more elements may be made for any one of the elements in the claims below or that a single element may be substituted for two or more elements in a claim. Although elements may be described above as acting in certain combinations and even initially claimed as such, it is to be expressly understood that one or more elements from a claimed combination can in some cases be excised from the combination and that the claimed combination may be directed to a subcombination or variation of a subcombination.
Insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalently within the scope of the claims. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements.
The claims are thus to be understood to include what is specifically illustrated and described above, what is conceptionally equivalent, what can be obviously substituted and also what essentially incorporates the essential idea of the invention.
