The present invention generally relates to container caps, and, more particularly, to enclosure caps with integrated timers to determine when the medication was last taken for vials, bottles, containers, and the like for pharmaceutical, drug, over-the-counter medications, nutraceutical, pet medications, or similar “smart” packaging applications. The timer has a centralized activation switch.
A container cap is typically used to selectively and removeably cover the open upper end of a container, such as used for pills or medication. One problem that arises with medication, both prescription and nonprescription, is that patients sometimes do not remember to take the medication at the designated times (e.g., every four hours). Alternately, sometimes patients do not remember when the last time that medication was taken. In an attempt to address these problems, various timing systems and timers have been developed.
Modern pharmaceutical practice relies on patients to consistently take their medication at one or more specific intervals during the day. Typically, the patient's doctor will create a medication schedule for the patient and instruct the patient to follow the schedule. However, this can become an issue: (1) since in our multi-tasking and multi-media based living and working environments, which competes for our attention spans, can impact the patient's ability to reliably remember when the last time they took their medication; (2) the patient's memory capacity can be impacted if they are elderly and/or dealing with the pain and stresses of illness; or (3) when the patient has multiple medications that may be taken at different times, the schedule can quickly become complex and unwieldy.
In an effort to simplify medication schedules and keep better track of when a particular medication was last taken, various products and methods have been developed. U.S. Pat. No. (“USPN”) 6,707,763, issued to Osberg, and hereby incorporated by reference as though set forth below in its entirety, discloses a pharmaceutical bottle timer cap that informs the user how long it has been since the medication in the bottle was taken. The Osberg timer cap automatically starts the timer when the cap is replaced on the bottle after the medication has been taken. But, the Osberg timer cap discloses and claims an activation switch that is biased on an outer edge. In this manner the timer is activated by the side pin being displaced directly by the lip of the bottle opening. Unfortunately, the side activation switch of Osberg requires the use of a relatively complex mechanism to translate the mechanical pin displacement to a resetting of the integrated electronic timer. As such, the Osberg side-pin activation switch requires a significant number of components that limits the reduction of the manufacturing costs of the timer cap and the improvements in the reliability of the switch properly working over repeated cycles of use. Also, the Osberg side-pin activation switch requires a different timer module design for each timer cap design that needs to be manufactured for each of the various sizes of pharmaceutical bottles and vials, this adds significant timer cap manufacturing and inventory costs. Cost and repeated-use reliability are key drivers for the high-volume consumer target markets of retail pharmacy, drug manufacturers, and managed health-care providers. Also, a timer cap with a side-pin activation switch has an inherent disadvantage compared to a timer cap with a center-pin activation switch as it does not leverage the benefits of mechanical symmetry, which help improve performance sensitivity and reliability. A timer cap with center-pin activation would enable a standard timer module design to be used for all sizes and styles of timer caps, which significantly reduces timer cap manufacturing an inventory costs.
Another example of a cap with a timer is U.S. Pat. No. 5,751,661, issued to Walters describes a closure cap having an integrated timer. The timer is activated and deactivated by a moveable disk that engages and disengages a battery beneath the timer. The timer cap, and more specifically, the moveable disk, described in the Walters patent, however, may be somewhat awkward and unreliable. The disk may stick in position if it is not properly aligned. Accordingly, the timer cap described in the Walters patent may be difficult to manipulate and may not provide an accurate indication of time. Also, the complexity of the design and the number of components required, make the manufacturing cost prohibitively high for the high-volume consumer markets.
Similarly, U.S. Pat. No. 6,324,123, issued to Durso, describes a programmable medication timer on a closure cap that indicates the appropriate time for the user to take medication. The timer described in the Durso patent, however, is very complicated and requires specific programming to remind the user to take medication.
U.S. Pat. No. 7,408,843, issued to Brandon, discloses a cap with a timer wherein the timer includes an interior activation post. However, the Brandon interior activation post is attached to a flexible diaphragm, wherein the diaphragm is separate from the sealing disk. Accordingly, the Brandon cap is very complicated, unreliable, and would be very expensive to manufacture.
Thus, there remains a long felt need in the art for an intelligent and easy-to-use timer cap that has a streamlined and cost-effective design that is achieved through the use of a centralized activation switch.
To minimize the limitations in the prior art, and to minimize other limitations that will become apparent upon reading and understanding the present specification, the present invention is a container cap with a timer. The timer has a centralized activation mechanism that activates the timer when the cap is secured to a container. The timer is used to determine how much time has passed since the cap was secured to the container.

In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings that form a part hereof, and in which is shown, by way of illustration, a specific embodiment in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.
In the following detailed description of various embodiments of the invention, numerous specific details are set forth in order to provide a thorough understanding of various aspects of one or more embodiments of the invention. However, one or more embodiments of the invention may be practiced without these specific details. In other instances, well-known methods, procedures, and/or components have not been described in detail so as not to unnecessarily obscure aspects of embodiments of the invention.
The term “container cap” refers to a lid, cap, top, topper, bung, stopper, cover, tap, seal, or closure of a container or bottle. The cap and container are preferably a pharmaceutical prescription safety cap and a pharmaceutical prescription bottle or vial, but they may be any cap or container without deviating from the scope of the invention, including those used for the packaging of over-the-counter medications, nutraceuticals, and pet medications.
The container cap is typically made of plastic or some other synthetic material, but any natural or man-made material may be used.
The timer incorporated into the container cap of the present invention is preferably a digital timer with a display that is automatically activated and deactivated when the cap is affixed to, or removed from, the container, however, the timer may be analog without deviating from the scope of the invention.
Although the drawings show the portions of the container cap being distinct or integrated, it should be understood the container cap may be made out of fewer or more parts without deviating from the scope of the invention.
The parts, portions, and/or pieces of the container cap of the present invention may be assembled through any device or means, including, but not limited to a snap-fit assembly, glue, epoxy, ultrasonic welding, clips, fasteners, and/or friction, without deviating from the scope of the invention.

The protective cover 5 shown in the drawings is preferably made from scratch resistant or self-healing polymer or gel and helps protect the timer 15 and any graphics on the container cap 10, or within the protective cover 5. The self-healing polymer may include, but is not limited to: epoxy resins, polymer gels, polyurethanes, latex, silicone, and butyl rubber, and/or polycarbonate sheets, which might include a hard-coat outer layer that uses a cold-flow mechanism to heal scratches to the hard-coat. The self-healing polymer usually has one or more layers.
Preferably, the timer 15 shows on display 17 the duration of time, in hours and minutes, since the timer 15 was activated. In this manner, the user knows when he or she last took the medication within the container 200. When the activation switch 105 is disengaged, the timer 15 stops, and the display 17, which is preferably digital, stops counting and ceases to display any numbers. The timer 15 is reset and re-started after the container cap 10 is re-engaged with container 200. Accordingly, it is very important that the activation switch 105 stay engaged until the container cap 10 is removed by the user, so that the user is not given a false duration of time since he or she last took the medicine. The present invention is streamlined and designed specifically for reliability, despite repeated engagement and disengagement of container cap 10 to container 200.
The timer locking tabs 519 and housing locking tabs 606 significantly improve the manufacturability of the container cap 10. Thus, the manufacturing costs are reduced by reducing the manufacturing assembly time and enabling replacement of faulty timer units in the container cap during the manufacturing functional test steps, thus reducing the overall manufacturing scrap rate. Furthermore, because the container caps 10 may be a disposable consumer product, the timer locking tabs 519 and housing locking tabs 606 also promote recycling and reclamation initiatives as the electronic components can be readily separated from the plastic components for appropriate recycling.

The removable child-proof safety ring 980 allows the closure cap to be used with any type of container that uses a child-proof or child-resistant opening. The removable child-proof safety ring 980 illustratively includes an upper portion 986 engaging adjacent outer surface portions of the upper housing portion 900 and a lower portion 987 connected to the upper portion 986 and being in radially spaced apart relation from adjacent surface portions of the lower portions of the housing 900. Therefore, the housing 900 can be readily inserted into the removable child-proof safety ring 980 so that the closure cap can be secured to a child-proof pill container as well as to a pill container having a threaded opening. This enables the closure cap on the same pill container to perform in either “child-proof” mode or be converted, by removal of child-proof safety ring, into “easy off” mode using the internal threads of the container opening.
The protective covers shown in the drawings is preferably made from scratch resistant or self-healing polymer or gel and helps protect the timer and any graphics on the container cap or within the protective cover. The self-healing polymer may include, but is not limited to: epoxy resins, polymer gels, polyurethanes, latex, silicone, and butyl rubber, and/or polycarbonate sheets, which might include a hard-coat outer layer that uses a cold-flow mechanism to heal scratches to the hard-coat. The self-healing polymer usually has one or more layers.
The said coil spring 1100 is preferably connected to the activation switch engagement portion 913 such that a lower portion of said coil spring 1100 matingly surrounds the activation switch engagement portion 913 and an upper portion of coil spring 1100 extends beyond the distal length of the activation switch engagement portion 913. The coil spring 1100 helps to push the activation mechanism 910 away from the timer 915 and ensures that the activation switch engagement portion 913 ceases to activate the activation switch 921 of the timer 915 when the container cap 899 is disengaged with the container 990.
