| 20110068105 | CONTAINER WITH SELF-VENTING FEATURES - A container includes a lid adapted to seal with a base. The lid and base rims each have vertical segments that mate upon sealing the container. The mating segments form a vertical seal zone. The vertical seal zone has a width extending across the rim surfaces. One or more vent channels are disposed on either or both rims. Each vent channel extends partially into the vertical seal zone. When pressure inside the container reaches a critical level, the lid rises and reduces the width of the seal zone, creating a vent point. Pressurized vapors traveling through the vent channel overcome rim-engaging forces at the vent point and pass through the engaged rims. Once pressure is purged, the lid descends and resumes its sealed arrangement with the base. The rims may respectively include horizontally oriented segments that engage each other to from a horizontal seal zone. | 03-24-2011 |
| 20100320210 | FOOD CONTAINER HAVING IMPROVED VENTILATION - A plastic food container for crisp or crunchy foods includes a lid adapted for sealing arrangement with a base. Exhaust vents are selectively disposed on the top surface of the container, such that when the container is closed, rising vapors in the container easily flow out of the container. The convection movement of rising hot vapors causes the induction of ambient air into the container through a first air intake port and a counterpart air intake port disposed between the two engaged rims. The first intake port and its counterpart allow inducted air to enter directly and horizontally into the container. One or more channels are formed in the floor of the base and are aligned with a line defined by the first intake port and its counterpart to allow for the cross flow of drier inducted air underneath the container's food contents. | 12-23-2010 |
| 20100181323 | FOOD CONTAINER HAVING IMPROVED TAMPER EVIDENT FEATURES - A plastic food container includes a lid adapted for sealing arrangement with a base. The rim of the base has an undercut formation adapted to receive the perimeter flange and flange tab of the lid when the lid and base are in the sealed arrangement. The flange tab includes an undercut release mechanism that allows a user to grasp a portion of the flange tab and initially open a sealed container via the extraction of the flange tab from the undercut formation by application of pulling force to the undercut release mechanism. The flange tab includes tamper evident means that provides visible indication that the undercut release mechanism has been utilized to initially open the sealed container. | 07-22-2010 |
