A lid is provided for covering or sealing a cup by engaging a rim flange of the cup. The lid includes a top portion and an annular side plate which extends downwardly from periphery of the top portion. The plate is formed with a hole. An engagement plate is disposed on the side plate. A bottom edge of the engagement plate is connected to the plate. A top edge of the engagement plate stretches upwardly along the hole, so that the engagement plate is located in the hole. The plates are flexible. As such, the engagement plate can be pressed and bent inwardly when the lid covers a cup. The engagement plate would then engage with the rim flange of the cup so as to enhance engagement of the lid and the cup.

A lid for a tote may include a main body including a plurality of raised surface features and a plurality of channels. The plurality of raised surface features may include a first raised surface feature and a second raised surface feature. The first raised surface feature may be separated from the second raised surface feature by at least one channel. A lip may circumscribe the main body and may include an opening having a boss extending downwardly from the opening. A plurality of connecting bridges may be coupled to the first raised surface feature and the second raised surface feature. A plurality of risers may extend from the lip to the main body of the lid.

A gas sampler device has a top plate with a concaved outer wall. The concaved outer wall allows users easily to lift the top plate off of the bottom plate without disturbing the bottom plate because the curved surface permits more positive contact between the outer wall and users' fingers. Moreover, the weight of the top plate is reduced by approximately twenty percent compared to conventional top plates, a feature that also makes it easier for users to lift the top plate off of the bottom plate.

A painting supplies storage device that prevents drying and settling of paint includes a container, which has an open top for addition of an open can of paint. A lid is selectively attachable to the container to sealably close the open top. A hole is axially positioned in the lid. A first rod is positioned through the hole and is rotationally and sealably attached to the lid. A lower end of the first rod is positioned proximate to a bottom of the container and its upper end protrudes from the lid. A plurality of paddles is attached to and extends from the first rod. A rotator assembly is attached to the upper end of the first rod to selectively rotate the first rod, whereby the paddles mix the paint. A shell, an upper facet of which is open, is attached to the container for stowage of one or more painting tools.

A food tray has a lower tray containing a first food product and an upper tray nested stably at least partly inside the lower tray, with the upper tray containing a second food product. An air permeable interface is provided between the upper tray and lower tray to allow venting of steam from the lower tray during cooking. A cover is provided for the food tray. Each of the lower tray and the upper tray are formed of a material that is suitable for use in a microwave or conventional oven. Various constructions may be used to create the air permeable interface, such as lugs, ledges and lips. The upper tray may sit above the lower tray. The trays are nested loosely for ease of removal of the upper tray from the lower tray. Various configurations of cover may be used such as a sleeve, carton or lid. The upper tray may contain the higher value food product.
