An audible signaling device mounted on a product container is actuated by the opening of the container. The signaling device comprises a power source, a memory for storing data corresponding to audible tones, an electronic sound generator for accessing the memory and generating audible tones, and a switch for connecting the electronic sound generator to the power source. The switch is responsive to the opening of the container whereupon audible tones are produced.

An audible tone generator externally mounted on a product container, the container comprising a compartment having an opening and a sealing member for sealing the compartment opening; said tone generator actuated by displacement of said sealing member relative to said compartment; the tone generator comprising: a power source; memory means for storing data corresponding to audible tones; an electronic sound generator for accessing the memory means and generating audible tones; and switch means having a first portion located on said compartment and a second portion located on said sealing member; said switch means being responsive to the separation of said first portion from said second portion upon the displacement of said sealing member relative to said compartment; whereby said switch means connects said electronic sound generator to said power source to produce the audible tones. A signal generator externally mounted on a pressurized beverage container, the container having a lid which includes a tab assembly and a pre-cut tab which is substantially detached from the lid to open the container, the signal generator comprising: a power source comprising a battery; an electronic storage means comprising a read-only memory (ROM) for storing data corresponding to audible tones; an electronic sound generator connected to said electronic storage means for accessing said storage means and generating audible tones; and a switch means for connecting said electronic sound generator to said power source; said switch means comprising an electronic circuit which monitors the electrical continuity of a circuit having a first portion located on said pre-cut tab and a second portion located on said lid; wherein said switch means changes state in response to an electrical discontinuity caused by the separation of said first and second portions upon the substantial detachment of said pre-cut tab. A method for providing a container having a compartment for receiving a product and an operative portal for accessing the product, comprising: providing a signal generator which includes: a power source; memory means for storing data corresponding to audible tones; an electronic sound generator for accessing the memory means and generating audible tones; and switch means responsive to the opening of said portal for connecting said electronic sound generator to said power source, whereupon the audible tones are produced, said switch means including a circuit having a first portion located on said compartment and a second portion located on said portal; and mounting said signal generator on said container external to said compartment; whereby opening the portal to access the product detaches said first circuit portion from said second circuit portion to activate the signal generator. An audible tone generator externally mounted on a pressurized product container, the container comprising a compartment having an opening and a sealing member for sealing the compartment opening; the sealing member having two configurations, a first configuration being substantially curved when the container is pressurized, and a second configuration being substantially flat when the container is depressurized; the tone generator comprising: a power source; memory means for storing data corresponding to audible tones; an electronic sound generator for accessing the memory means and generating audible tones; and switch means being responsive to the change in the configuration of said sealing member to connect said electronic sound generator to said power source to produce the audible tones when said container is depressurized.
