4. Audio echo canceller system according to claim 1, characterized in
an attenuator following said first adder configured to multiply first adder output with 12 to form said non-delayed mono signal.
5. Audio echo canceller system according to claim 1 or 4, characterized in that the first and second L andor R deduced signal are multiplied with a first gain Gi, respectively, before being loaded into said one or more left and one or more right loudspeaker(s).
6. Audio echo canceller system according to claim 5, characterized in that the first L andor R deduced signal is L, and the second L andor R deduced signal is R.

8. A method in an audio echo canceller system providing an echo attenuated output signal from an echo added input signal including near-end audio in addition to an echo contribution originating from a far-end audio presenter unit receiving a left (L) and a right (R) audio signal, characterized in
adding L and R to create a non-delayed mono signal,
delaying said non-delayed mono signal with a predefined time to create a delayed mono signal being loaded into a one or more main loudspeaker(s),
respectively loading a first and a second L andor R deduced signal into one or more left and one or more right loudspeaker(s).
9. A method according to claim 8, characterized in that said step of delaying is carried out in a first filter (Hm).
10. A method according to claim 8 or 9, characterized in
adding R filtered by a second filter (Hc) with L filtered by a third filter (Hd) to create said first L andor R deduced signal,
adding L filtered by said second filter (Hc) with R filtered by said third filter (Hd) to create said second L andor R deduced signal.
11. A method according to claim 8, characterized in that the step of adding L and R to create a non-delayed mono signal further includes attenuating the result with 12 to form said non-delayed mono signal.
12. A method according to claim 8 or 11, characterized in
respectively multiplying the first and second L andor R deduced signal with a first gain Gi before being loaded into said one or more left and one or more right loudspeaker(s).
13. A method according to claim 12, characterized in that the first L andor R deduced signal is L, and the second L andor R deduced signal is R.
14. A method according to claim 12, characterized in
subtracting said non-delayed mono signal multiplied with a second gain Ge from L, to create the first L andor R deduced signal,
subtracting said non-delayed mono signal multiplied with the second gain Ge from R, to create the second L andor R deduced signal.

1.-21. (canceled)
22. A container comprising:
a body having at least one wall defining at least one cavity for storing dispensable contents and a rim surrounding the cavity and defining a larger opening for filling the cavity;
a cover affixed to the rim to close the larger opening; and
a portion of the body forming a lid, the lid being connected to the body by the cover and a frangible connection, the frangible connection being formed at a transition between the lid and the at least one wall, the cover and at least a portion of the frangible connection at the at least one wall defining a smaller opening for dispensing contents from the cavity upon severance of the frangible connection.
23. A container according to claim 22 further comprising a hinge formed by at least the cover for the lid.
24. A container according to claim 23 wherein the hinge is formed by the cover and the rim.
25. A container according to claim 22 wherein the lid portion includes an exterior surface with a profile complimenting a finger.
