Aspects of the subject disclosure may include, for example, a container bolt seal, comprising: a rod portion having first and second ends; a head located at the first end of the rod portion, wherein at least one outer cross-sectional dimension of the head is greater than a largest outer cross-sectional dimension of the rod portion; a locking member, wherein at least one outer cross-sectional dimension of the locking member is greater than the largest outer cross-sectional dimension of the rod portion, wherein the locking member is configured for placement on the second end of the rod portion, and wherein the locking member becomes non-removably attached to the rod portion after placement on the second end of the rod portion; and an electronic processor that facilitates wireless communications comprising a first message indicative of a time and location of a bolt-sealing event and a second message indicative of a time and location of a status event. Other embodiments are disclosed.

An audio signal analysis method is provided for detecting the opening and closing of a medicine bottle cap in a robust manner using a micro speaker and a microphone along with associated mixed signal electronics. It is also used for robust tamper detection and for monitoring liquid medication consumption accurately. In a preferred embodiment an un-modulated OFDM signal is used that covers the entire operating audio spectrum. In another embodiment, Complimentary code based phase encoding of the subcarrier phases is used to reduce the peak to average power of the OFDM signal, thereby enabling higher transmit power of the audio signal to mitigate against interference. A suitable wireless device can be co-located with the mixed signal electronics for sending the bottle usage, medication reminder alarm, and tamper status to the medication compliance monitoring system or to the user's cell phone. In some embodiments of the patent, electrical capacitance sensing is used to determine if the bottle is opened or closed.

A wireless (e.g., near field or RF) communication device, and methods of manufacturing and using the same are disclosed. The wireless communication device includes a receiver and/or transmitter, a substrate with an antenna thereon, an integrated circuit, and one or more protection lines. The antenna receives and/or transmits or broadcasts a wireless signal. The integrated circuit processes the wireless signal and/or information therefrom, and/or generates the wireless signal and/or information therefor. The integrated circuit has a first set of terminals electrically connected to the antenna. The protection line(s) are on a common or different substrate as the antenna. The protection line(s) sense or determine a continuity state of a package or container on which the communication device is placed or to which the communication device is fixed or adhered, and are electrically connected to a second set of terminals of the integrated circuit different from the first set of terminals.

A dispensing closure (40) with non-frangible tamper evidence features includes a body (54) having a locking pin (68) with an initial configuration and a locking configuration moved relative to the initial configuration when engaged by a portion of a container (44) or a spout (60). The closure (40) includes a lid (56) connected to the body (54) and is movable between an initially closed position, an open position, and a subsequently closed position returned from the open position. The lid (56) has an aperture (94) and a tamper evidence tab (96), wherein, in the initially closed position of the lid (56), the locking pin (68) is located in the locking configuration and the tamper evidence tab (94) is retained beneath the locking pin (68). In the subsequently closed position of the lid (56), the tamper evidence tab (94) is rotated laterally outwardly into the aperture (94) to indicate evidence of tampering to a user.

Closure devices and kits allow closure of an open-ended container and provide a visible indication of closure torque. The closure device will include an outer cap defining a torque indicator window, an inner cap nested within the outer cap and a torque indicator disc positionally fixed to an upper surface of the inner cap and having at least two different indicia regions angularly adjacent to one another. The outer and inner caps are in mechanical interference fit with one another such that turning movement applied to the closure device allows the outer and inner caps to be turned as a unit and threadably coupled onto a threaded container until the inner cap is frictionally engaged with an edge of the container. Thereafter, continued turning movement of the outer cap relative to the inner cap causes angular displacement of the indicator window relative to the torque indicator to thereby provide a visible indication through the indicator window of an indicia region indicative of sufficient closure torque.

Aspects of the disclosure relate to sealing devices, methods, and systems. A sealing device may be configured to seal a container. The sealing device may send or trigger a message indicating the current geographic location of the sealing device based on the sealing device being removed from the container.
