The valve ( 1 ) is arranged to open in response to an excess pressure generated inside the package ( 2 ) upon heating of said package ( 2 ). The valve comprises an opening ( 4 ) formed in the package ( 2 ), on top of which opening ( 4 ) an adhesive layer ( 5 ) is applied. The valve ( 1 ) is also arranged to emit a sound signal when subjected to said pressure load.
