Abstract (en)
[origin: WO2007091951A1] A valve system for a container (4, 5), especially for food containers whose contents are intended to be heated, comprises an adhesive layer (3) arranged over an opening portion (6) in the container (4). The adhesive layer (3) is arranged to at least partly release the container (4) adjacent an opening portion (1) in the adhesive layer in case of overpressure and thus form an opening to allow a flow out of the container (4, 5) and, in this flowing- out, emit an acoustic signal by means of said opening portion (1) in the adhesive layer (3) which is made to oscillate by the flow. The valve system comprises at least a second opening portion (2) arranged, in heating of the contents of the container (4, 5), to open before the above-mentioned opening portion (1) in the adhesive layer (3).
