DESCRIPTION OF THE PREFERRED EMBODIMENTS The following will describe specific embodiments of the easy open end of the present invention with reference to the drawings. FIGS. 1-5 show an embodiment 10 of the easy open end of the present invention for use in drinking water cans commonly used in pull-tab cans. The easy open end 10 uses a normal aluminum pull tab can top 11 in which the pull tab 14 is raised to open the opening 13 and when the pull tab opening 13 is opened, information prepared in advance is prepared. Made on the emanating lid. In this case, the easy open end 10 is designed to emit sound on an audio device, i.e. speaker 20. For this purpose, the easy open end 10 has an insulating film 16 extending over the pull tab opening 13 and the peripheral portion 15 thereof on the surface 12 of the aluminum upper lid 11 which is exposed to the outside air, and is provided with a predetermined force. Affixed releasably, battery 18,
An electric output circuit 19, an information generating device 20, and an electric wiring 21 are attached on the insulating film 16 at a peripheral portion 15 thereof, and the battery 1 is connected to the electric wiring 21 by the electric wiring 21.
8, a wiring portion 26 for connecting the electric output circuit 19 to
Affixed on the insulating film 16 in a state where it can be cut by a predetermined force and extends from the peripheral portion 15 to the pull tab opening 13.

The insulating film 16 is punched out of a thin resin sheet into an L-shape of a predetermined size, and is extended to the surface of the pull tab opening 13 and its peripheral portion 15 on the surface 12 of the upper lid 11 which comes into contact with the outside air, and It is peelably adhered by the force of. In particular, the tip portion 17 of the insulating film 16 is placed in a turned-up shape without being attached, so that the insulating film 16 can be easily picked up and peeled off. The insulating film 16 is in a state where the pull tab 14 is not pulled, that is, in a state where the pull tab opening 13 is integrated with the upper cover 11 and the pull tab opening 13 is not opened. The electric wiring 21
Is brought into contact with the aluminum cover 11 and the electric output circuit 19 is energized to prevent the operation of the electric output circuit 19 from occurring. Of course,
This insulating film 16 is similarly used for a pull-tab can made of a conductive metal such as aluminum, for example, steel.

The battery 18 is a lithium battery. The electric energy of the lithium battery 18 is gradually attenuated due to spontaneous discharge, and can no longer function as a power supply in about one year. Using this property,
If no information, for example, sound, light emission, discoloration, or the like is generated even when the pull tab 14 is caused, it can be determined that the content has passed the expiration date. That is, such use becomes possible.

The electric output circuit 19 includes a semiconductor integrated circuit (IC) 2 in which a resistor 22, an inverter 23, and a speaker drive circuit 24 are stored in a chip.
5 and connected to the lithium battery 18 and the speaker 20 by the electric wiring 21. The electrical wiring 21 uses thin copper foil for the wiring part 26 connecting the resistor 22 to the lithium battery 18, and the wiring part 26 of the copper foil extends from the peripheral part 15 to the pull tab opening 13. And folded over the insulating film 16. As such, the wiring portion 26 is severed by the force when the pull tab 14 is raised and the pull tab opening 13 is opened, and a circuit change is automatically generated inside the IC chip 25. Designed for switches.

[0010] Since the wiring portion 26 functions as a switch of an electric circuit, the IC chip 25 has a speaker in a state where the wiring portion 26 is not cut, that is, the pull tab 14 is not raised. O
The electric circuit is designed to keep the FF and keep the speaker ON in a state where the wiring portion 26 is cut, that is, in a state where the pull tab 14 is raised.

Next, the Easy Open End 1
0 is used for the drinking water aluminum pull-tab can and describes the operation of producing a sound. When the pull tab 14 is not raised as shown in FIG. 1, that is, when the pull tab opening 13 is not opened, current flows from the lithium battery 18 as shown in FIG. The potential at the point A flowing through the resistor 22 becomes the H level on the plus side of the battery. At this time, the speaker drive circuit 24 is kept in the OFF state, and the speaker 20 is kept always in the OFF state, and does not emit sound.

When a human wants drinking water and the pull tab 14 is raised as shown in FIG. 4 and the pull tab opening 13 is opened, the electrical wiring 21 extends to the wiring portion extending into the pull tab opening 13. 26 2 places 2
At 7, 28, the current stops flowing through the resistor 22 as shown in FIG. 5, and the potential at the point A becomes the L level on the negative side of the battery. At this time, the speaker drive circuit 24 is turned ON, and a current flows from the speaker drive circuit 24 to the speaker 20, and the speaker 20 emits sound.

[0013] It is desirable that the sound generated in such a manner be prepared assuming appropriateness in advance. For example, in a juice can, the pull tab 14 is raised to open the pull tab opening 13 and at the same time emit a simple melody such as “Pampakapan”, and the child is pleased. For beer cans for adults, it is also possible to make a sound such as "It's time to drink" or "Make it cool." Further, in response to a special order from a consumer, a store, or the like, a specific message, for example, a voice such as “XX Chan. This is a gift from grandpa” can be emitted.
This makes it possible to add toy-like fun to the pull-tab can, which contributes to differentiation of the beverage in the pull-tab can. In addition, the audio can be used for commercials. For example, to advertise your company's products, "Please try our newly-released OOOO" or undertake the promotion of a product from another company and say, "XOO's refrigerator is best for cooling beer." , Etc. can also be emitted. In addition, as a public commercial, a sound such as "Let's stop throwing out empty cans" can be issued. That is,
Pull tab cans can be used as advertising media.

When the drinking water is consumed and the pull-tub can is used, the insulating film 16 is easily peeled off from the used pull-tab can by pinching the tip portion 17 thereof, and is attached to the insulating film 16. Lever battery 18, electric output circuit 1
9, the information generating device 20, and the electrical wiring 21 are also removed from the pull-tab can, and the pull-tab can is made recyclable.

The above-described easy open end 10 is used for a normal aluminum pull-tab can, but is also used for a steel pull-tab can. That is, the easy open end 10 can be used for a can made of a conductive metal. In the easy open end 10, the electric output circuit 19
Although the audio device driving circuit 24 has been described as the speaker driving circuit and the information generating device 20 has been described as the speaker as the audio device, the electric output circuit 19 has a light emitting device driving circuit instead of the speaker driving circuit 24. , A color-developing device driving circuit, or a character display device driving circuit, and when the information generating device 20 is replaced with a light-emitting device, a color-developing device, or a character display device corresponding to the driving circuit, an optical signal or Display by change, character display, and the like are also possible. In addition, if a temperature sensor for detecting the temperature inside the can is incorporated in the electric output circuit 19, it is possible to display a good drinking time. Further, since the lithium battery 18 cannot function as a power supply in about one year after the electric energy is gradually reduced due to spontaneous discharge, the pull tab 14 is caused to take advantage of the property to cause the pull tab opening 13 to be used.
If no sound, light emission, discoloration, or the like is output even when is opened, it is possible to identify the content as having passed the expiration date. Furthermore, if the electric output circuit 19 incorporates a microcomputer having the function of a clock, it is possible to measure the elapsed time of a certain period of time, store it, and retrieve it as electronic information. Or it can be output as a display.

As such, the wiring portion 26 is severed by the force when the pull tab 14 is raised and the pull tab opening 13 is opened, and the IC chip 2
5 is designed to be a switch in which a circuit change is automatically generated.

The lithium battery 18 and the electric output circuit 1
