FOOD PACKAGE

摘要

Food package comprising two packaging elements joined, e.g. by hot welding, along a tearable joining seam (1) extending substantially along the periphery of the two packaging elements so as to delimit in an airtight manner an internal volume (2) for receiving the packaged food product. The package is primarly intended for cooking or heating the food product in the package by placing the latter in hot or boiling water. In order to avoid bursting at the excess pressure of vapours and/or gases in the package produced in connection with the heating, the package is provided with means for liberating vapours and gases from the internal volume of the package to the surroundings, as well as means for avoiding liquid from the surroundings penetrating into the internal volume of the package via the means for liberating vapours. The means for liberating vapours and gases comprise a valve aperture (3) that is opened when a first part (3) of the joining seam is torn open. The means for avoiding liquid from the surroundings penetrating into the package comprise a buoyancy member (4) situated adjacent the valve aperture (3).
