Abstract
A closure for pharmaceutical containers and the like, provided with means to record and display the time elapsed since the closure was last removed from the container.
The closure, as an aid to memory, is provided with a pressure switch such that when the closure is removed from a container, the record of elapsed time is reset to zero elapsed time. The closure, when replaced on a container, resumes its function of recording elapsed time since the container was last opened. The time record thus provided, greatly reduces the risk of both overmedication and the inadvertent omission of required doses, being generally an aid to memory in the regulation of self-administered pharmaceuticals. Designed to replace existing closures, the closure of the invention ensures that medications will remain in the container of their dispensation, and will thereby, continue to be associated with the information provided thereon.

Description
CLOSURE WITH INTEGRAL TIME KEEPING DEVICE
The present invention relates to closures for containers, especially to closures used on pharmaceutical containers. Such closures are commonly termed caps.
Various types of caps are known to be used to close pharmaceutical containers, none are known to provide an aid to memory. For many persons taking medication over an extended period of time, dose control becomes a problem when the act of taking a medication becomes mechanical and unthinking. The probability that a 10 person will double dose or miss a dose, increases with the increasing duration of a drug therapy. The risk is greatest for persons, such as the applicant, who are on long-term drug maintenance programs.
With respect to pharmaceutical regimens, the most common aid to memory in dosage control has been a simple array of several small compartments, each provided with an independent closure. The compartments, of which there are normally seven - one for each day of the week - are often conjoined into a single linear unit. More complex square arrays are available and may contain as many as 35 compartments. The medication to be controlled is removed from its dispensing 20 container and placed in the compartments of the array. The array can be consulted occasionally and the medication in the compartment representing a specific day or time can be administered once and only once.
The primary deficiency of the arrayed compartment aid to memory is that it requires the removal of the medication from the container in which it was originally dispensed. This results in the loss of most of the information that was provided with the medication. The name of the person for whom the medication was prescribed, the name and concentration of the drug itself, the ailment being treated, the date of dispensation, the dosage instructions from the prescribing physician, and the contraindications and warnings from the dispensing pharmacist, are all lost when arrayed compartment devices are employed.
A secondary and inherent deficiency of the arrayed compartment aid to memory is the physical size of the array. The entire array is significantly larger than most 10 pharmaceutical containers. This is often an inconvenience, and can deter some patients from carrying their medications on their person.
It is desirable to have a pharmaceutical container that directly incorporates an aid to memory and that does not, therefore, result in the separation of a medication from its relevant information. The most direct and useful method of incorporating an aid to memory device in a pharmaceutical container is to place it within the closure or cap portion of the container. The record of time elapsed since the closure of the invention was last placed on a pharmaceutical container, greatly reduces the risk that a patient will inadvertently either overdose, or under dose. Furthermore, where 20 the closure of the invention is employed to replace a standard cap on a pharmaceutical container, the new combination of container and replacement closure is not appreciably larger than the original combination as dispensed. The new combination is considerably smaller than any known arrayed compartment device, and as such, it is much more likely that a patient will carry their medication on their person. More importantly, the new combination obviates the primary deficiency of the arrayed compartment aid to memory, by ensuring that medications remain physically associated with the relevant information that was dispensed therewith.
Further benefits of the closure of the invention arise in the circumstance wherein a patient becomes incapable of self-administering a medication. In a medical emergency, the closure of the invention provides two more benefits that are additional to its aid to memory function. Firstly, and insofar as the closure of the invention increases the probability that a patient will have his or her medication on 10 their person, the retention of the dispensing information with the medication, permits other persons on scene to identify a medication found in the possession of a patient, and thereby determine if the medication may be related to the patient's present condition. Secondly, it provides to other persons on scene, a reliable record regarding the time elapsed since the medication was last self-administered.
The closure of the invention is designed to replace existing caps used to seal standard sized pharmaceutical containers and the like. The closure, as an aid to memory, provides the user with an exact and continuous record of the time elapsed since the conlai, ler was last opened. The closure of the invention consists of a time 20 keeping device, a battery, a pressure switch, and a display device. The pressure switch is so arranged that when the closure is removed from the container, the time keeping device is deactivated and reset to zero elapsed time. The closure, when next replaced on the container, resumes its function of recording the elapsed time since the container was last opened.
No closure with an integral time keeping device that is specifically designed to replace the standard caps now used for pharmaceutical dispensing containers, has been described or produced.
The invention, as exemplified by a preferred embodiment, is described with reference to the drawings in which:
Figure 1 is a top view of the preferred embodiment of the closure.
Figure 2 is a sectional view of the closure shown in Figure 1.
Referring to Figure 1, the embodiment of the invention shown, a closure with integral time keeping device, comprises a body portion with a knurled outer circumference 10, a liquid crystal display 12 on the upper surface of the body 10, and embossed lettering 14 on the upper surface of the body, serving to identifying the correct orientation for reading the liquid crystal display 12.
Referring to Figure 2, the embodiment of the invention shown, a closure with integral time keeping device, comprises a body portion 10, where, interior to the body portion 10, are disposed a multiplicity of protuberances 20, arranged along the 20 lower inner surface of the body 10, which when engaged by the opposite members of a pharmaceutical container, force the closure down onto the container. A pliable gasket element 22, then contacts the upper rim of the container and is thereby deformed. As the gasket element 22 is compressed, a rigid non-conductive annular element 24, is forced upward, in turn forcing a resiliently flexible disk-shaped conductive metal membrane 26, to impinge upon one pole of an electric storage battery 28. This contact, completes an electric circuit, sending power to the electronic time keeping device 30. Both the battery and the time keeping device are immovably mounted on a rigid, disk-shaped conductive metal mounting element 32.
The activated electronic time keeping device 30, commences to record elapsed time, said record being continuously transmitted to a digital liquid crystal display device 12, by means of a multi-conductor element 34.
In operation, the closure of the invention, in its preferred embodiment, provides 10 an aid to memory in the form of an elapsed time record. The closure of the invention is a self-contained mechanism, inclusive of a power source in the form of a battery, a time keeping device, preferably in the form of an electronic time keeping device, a display device, preferably in the form of a digital liquid crystal display, and a pressure switch that regulates the supply of electrical power to the time keeping device, depending on the state of the closure being affixed to a container or otherwise.
When the closure of the invention is affixed to a container, the pressure switch is compressed, thereby completing an electric circuit, thereby permitting power to flow from the battery to the electronic time keeping device, initiating said device to 20 continuously record the time elapsed since the electric circuit was established. The electronic time keeping device continuously sends a record of elapsed time to a digital liquid crystal display device. By these means, the number of hours and minutes elapsed since the closure was last removed, is continuously displayed.
When the closure is removed from a container, the electric circuit is interrupted, thereby erasing the record of elapsed time, and essentially resetting the device to zero.
In the preferred embodiment of the closure of the invention, the time keeping device and the display device are capable of recording and indicating elapsed times of up to ninety nine hours (99 hr) and fifty nine minutes (59 min). For a patient on a once per day drug regimen, an indicated elapsed time provided by the closure of the invention of greater than 20 hours as an example, would remind the patient that he or she had yet to take their medication for that time interval. Conversely, if the same 10 patient were to find an indicated elapsed time provided by the closure of the invention of less than 3 hours as an example, it would inform the patient that it is likely that he or she had already taken the medication for that time interval. For the patient on a medication regimen of three doses per day, an indicated elapsed time provided by the closure of the invention of approximately eight hours would indicate that another dose was due presently.
The aid to memory provided by the closure of the invention, does not require the separation of a medication from its original container. The prior art of arrayed compartments requires such a separation. Furthermore, the closure of the invention 20 is smaller and more convenient to carry on one's person than are arrayed compartments.
