20140027446 | SELF VENTING STEAM VALVE FOR FLEXIBLE PACKAGING BAGS AND POUCHES USED IN COOKING OF FOODS - The present document describes a cooking container for cooking foodstuff comprising: an edge having a seal separating the interior from the exterior of the cooking container; a steam valve formed in the seal, the steam valve comprising: a pressure accumulating portion; a pressure controlling portion; and a breakable seal between the pressure accumulating portion and the pressure controlling portion; whereby the breakable seal is breakable under an increase in pressure in the pressure accumulating portion during cooking thereby forming a gap/passage in the seal and permitting controlled evacuation of pressure from the interior of the cooking container through the gap/passage to the exterior, the pressure controlling portion restricting the evacuation of pressure relative to the pressure accumulating portion after the breakable seal is broken. | 01-30-2014 |
20120187122 | REPOSITIONABLE LIDDING FILM- SEAL ACTIVATED - The present document describes a package for distributing and storing produce comprising: a container for holding produce, the container comprising a peripheral edge defining an opening into the container; a film for being positioned onto the peripheral edge of the container to close the opening; and an adhesive material for providing an airtight seal between the film and the peripheral edge upon being activated once the film has been positioned to cover the opening; and wherein upon being activated, the adhesive material populates both the peripheral edge and the film, the film thereby being repositionable onto the peripheral edge to reclose the opening of the container once the airtight seal has been broken upon initial opening of the package. | 07-26-2012 |
20120031795 | GAS PERMEABLE POLYMER LABEL FOR CONTROLLED RESPIRATION - The present document describes a label for installation over an opening of a container to be loaded with produce. The label comprises: a polymer-based film; and micro-perforations through the polymer-based film, whereby upon the polymer-based film being sealingly installed over the opening of the container, the micro-perforations controllably transfer a gaseous substance (such as oxygen and/or carbon dioxide) into or out of the container, through the label, and according to a respiration rate of the produce to be loaded in the container. | 02-09-2012 |
20100170894 | MICROWAVEABLE POUCH CAPABLE OF CONTROLLED RESPIRATION FOR EXTENDED SHELF LIKE OF PRODUCE CONTAINED THEREIN - The present document describes a cooking container for foodstuff in the form of a pouch made of a microwaveable heat-sealable polyester film. The polyester film comprises micro-perforations allowing controlled respiration of the film while maintaining atmospheric pressure inside the pouch. | 07-08-2010 |
