ABSTRACT:

FIELD OF THE INVENTION
The invention described and claimed herein comprises a lid or cover closing the top of a container or receptacle, where said cover contains a built-in device that alerts the user when the container is opened and will emit an alarm so that the user can respond and perform a subsequent action such as closing the container or receptacle.
SUMMARY OF THE INVENTION
Bottles, containers and other receptacles containing hazardous or volatile materials, or materials which react with air, are used for different purposes in locations such as chemical and biochemical laboratories, industries and hospitals. At times, a user, such as a scientist, may fail to recap a bottle or container after use, resulting in the escape of hazardous materials such as gases or vapors into the atmosphere resulting in harm to the user and the environment. Often such gases can reach toxic levels when permitted to flow out of a container for an extended time period. Therefore, a device, which can alarm the user when a bottle or container is opened, can prevent the release of toxic substances into the environment and work settings such as a laboratory. Currently, there is no such device, which can warn a user, through an alarm system, that a bottle is open so that the user can perform an action to respond to the situation.
The invention described herein, is a low cost and simple warning device. The device may have following properties:
It contains an alerting system based on emitting a light or sound alarm.
It is easy to use and low cost.
It comprises a universal system that can be used with any lid or cover for any bottle, container or receptacle.
It can send a signal to a remote location through a wireless system, such that a user situated at a distance from the lid or cover can receive and respond to an emitted alarm signal.
The various features of novelty, which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its advantages and objects, reference is made to the accompanying drawings and descriptive matter in which a preferred embodiment of the invention is illustrated.
