Description:
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.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawings, the invention is an alarm sensor ( 1 ) in the form of a flat strip or encapsulated in a case. The size of the device is such that it can be easily attached to the cover or lid ( 2 ) of a bottle, receptacle or container ( 3 ). The cover ( 2 ) may have the alarm system ( 1 ) either built-into the cover itself or attached to the cover through the use of any permanent or temporary adhesives or attachment systems, such as Velcro. 
     Once a user opens the lid or cover ( 2 ) the switch ( 4 ) in the alarm system ( 1 ) activates immediately, or after a predetermined period of time, resulting in the activation of the alarm system ( 6 ) and the transmission of a signal. The circuit can be powered by a battery ( 5 ). The signal source can be a light emitting diode (LED), which emits light to alert the user that the lid or cover has been removed from the aperture or opening of the container, bottle or receptacle. Other alerting systems can consist of, but are not limited to, frequency generators emitting infrared light, radio frequency, ultra sound, and sounds at 900 mega hertz ranges. 
     Furthermore, the alarm system ( 6 ) can be a wireless radio transmitter, which is activated as soon as the switch is turned on, when it closes the circuit. The alarm system then sends a signal to a wireless receiver ( 8 ). The receiver is activated when a signal from the lid/cover device ( 1 ) is received. The receiver can then transmit a sound, light or any other type of signal or alarm to alert the user to respond. 
     In FIG. 3, a contact switch ( 7 ) is attached to the bottle ( 3 ). Said switch is activated, when the lid or cover ( 2 ) containing the alarm device ( 1 ) is removed from the bottle ( 3 ). In this case the alarm device is activated by a magnetic, contact switch or any other type of switch ( 7 ), which is attached to the lid or cover ( 2 ) attached to the bottle or container ( 3 ). 
     The device ( 1 ) can have a delay switch, so that the alarm ( 6 ) is activated after a time delay. This may be necessary because a user needs some time to perform a desired action with the opened bottle. After a certain time period has passed, the user may need to be reminded to close the bottle or container ( 3 ) so that toxic or other substances contained in the bottle ( 3 ) will not be released into the environment. Once the user closes the container ( 3 ) with the lid or cover ( 2 ), the alarm system ( 6 ) will reset will go into sleep mode until the container is opened again. 
     Furthermore, other sensors ( 9 ) can be attached to the same circuit, as shown in FIG. 4, or in separate circuits with or without the alarm device ( 1 ). Such sensors ( 9 ) can be used to detect different physical and chemical properties such as temperature, concentration of gases, wetness levels and the presence of smoke. The sensors ( 9 ) can also be programmed so that they can send data to a receiver ( 8 ) from time to time. Such a receiver ( 9 ), which may be wireless, can be located at a remote location so that a user can receive signals at different locations relative to the lid or cover ( 2 ) and the bottle or container ( 3 ). 
     The switch ( 4 ) may be a tilt switch such as a mercury switch, a level sensor or any other type of switch. Furthermore a magnetic switch, a Hall effect switch or a light switch can be used to activate the alarm. The switch ( 7 ), as shown in FIG. 3, may be a contact switch, a Hall effect switch, a magnetic switch, an optical switch or any other type of switch. 
     The alarm device ( 6 ) can be, but is not limited to, an inductive coil or a frequency transponder with a switch but without a battery. The activation energy for the transponder or inductive coil can be received from a receiver or an outside source. 
     The broader usefulness of the invention may be illustrated by the following examples. 
     EXAMPLE 1 
     Use of an Alarm-emitting Device as an Attachment to the Cover of a Bottle Containing Liquid Bromine. 
     An alarm-emitting device is attached to the cover of a bottle containing liquid Bromine. The device is attached with Velcro or some other type of adhesive. When the cover is removed, the device emits an alarm, either immediately or after a predetermined period of time. This alerts the user that the hazardous bottle is open. The user can then respond by closing the lid or cover, preventing the release of Bromine vapors into the laboratory air or environment. 
     EXAMPLE 2 
     Use of an Alarm-emitting Device in the Cover or Lid of the Gasoline Tank of an Automobile 
     An auto driver needs to open the cover to the gasoline tank and remove the lid from the opening of the tank to fill gasoline into an automobile. After such an action is performed the driver may forget to screw the lid or cap to the tank back into its position. If a alarm device were built into or attached to the gasoline tank lid, such a device would emit a signal after a predetermined time period preventing the driver from forgetting to screw the lid back onto the gasoline tank. The alarming system used for this purpose could be local or wireless and consist of any type of signal such as light or sound.
