Abstract: A container includes a lid and a base. The lid includes a lid rim and a skirt extending downwardly from the lid rim. The base includes a base rim and a base flange extending outwardly from the base rim. The skirt overlaps the base flange when the container is in a closed configuration, and the skirt includes a sealing ring that engages the base flange to seal the lid to the base in the closed configuration. A plurality of cut-outs are formed in the sealing ring that alleviate concentration of friction between the sealing ring and the base flange when a force is applied to separate the lid from the base.

Abstract: A container includes trays having a substantially identical profile. For each tray, the tray includes a rim that includes a proximal segment and a bead segment, the bead segment includes an upwardly-extending member and a downwardly-extending member, the upwardly-extending member defines a first cavity, and the downwardly-extending member defines a second cavity. When the trays engage to close the container, the upwardly-extending member of a first tray is received in the second cavity of a second tray, and the upwardly-extending member of the second tray is received in the second cavity of the first tray. When the first tray and the second tray are stacked, movement of the second tray relative to the first tray is limited by the upwardly-extending member of the first tray engaging the rim of the second tray, and/or by the downwardly-extending member of the second tray engaging the rim of the first tray.

Abstract: A container includes trays having a substantially identical profile. For each tray, the tray includes a rim that includes a proximal segment, a bead segment, and at least one vent channel defined in the proximal segment, the bead segment has an upwardly-extending member and a downwardly-extending member, the upwardly-extending member defines a first cavity, and the downwardly-extending member defines a second cavity. When the trays are engaged to close the container, the upwardly-extending member of the first tray is received in the second cavity of the second tray, the upwardly-extending member of the second tray is received in the second cavity of the first tray, the first and second trays define an interior volume of the container, the proximal segments of the rims of the first and second trays are in face-to-face contact to substantially seal the interior volume, and each vent channel is in communication with the interior volume.

Abstract: A food container system for a take-out main course food item includes a plastic lid adapted for sealing arrangement with a plastic base and one or more securable inner vessels adapted to hold an accessory food item. The floor of the base includes one or more first vessel-receiving mechanisms designed to locate and receive the bottom of a securable inner vessel. The lid includes one or more second vessel-receiving mechanisms, each designed to receive and engage the top rim of a securable inner vessel when such vessel is received by a first vessel-receiving mechanism and the lid and base are in the sealed arrangement. The engagement of the top rim of a vessel by a second vessel-receiving mechanism of the lid results in a leak resistant seal between the vessel and the lid.

Abstract: A new approach to radar imaging is described herein, in which radar pulses are transmitted with an uneven sampling scheme and subsequently processed with novel algorithms to produce images of equivalent resolution and quality as standard images produced using standard synthetic aperture radar (SAR) waveforms and processing techniques. The radar data collected with these waveforms can be used to create many other useful products such as moving target indication (MTI) and high resolution terrain information (HRTI). The waveform and the correction algorithms described herein allow the algorithms of these other radar products to take advantage of the quality Doppler resolution.

Abstract: 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.

Abstract: 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.
