Abstract

The present invention concerns a single-use valve (1) for mounting on a package (2), particularly food packages the contents of which are to be heated in a microwave oven (3). 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.
