A lid system for use with a container having an opening bounded by a rim, with at least one outwardly extending projection extending from the rim, includes a lid and a lid cover member. The lid is sized to seat on the rim of the container and includes an upper surface, at least one section with perforations extending therethrough, and a centrally disposed lid handle. The lid cover member is sized to seat adjacent the upper surface of the lid around the lid handle. The lid cover member is rotatable about the lid handle to substantially close or expose the at least one section with perforations. The lid cover member includes at least one bracket for mating with the at least one outwardly extending projection on the rim of the container to retain the lid on the container during a draining process of the container.

Steam directional condensation structure of cover body, wherein he internal side of the lid provides with a curved groove surface for generating steam vortex; along the section of the protrusion part, a protrusion part is provided at one side for conducting the condense droplet back to the cookware. Because the curvature of the curved groove surface is greater than that of the inner surface of the lid, the water in the cookware boils to produce a large amount of steam the steam will form a vortex in the curved groove surface, so that the steam can fully contact the curved groove surface to condense, and at the same time, after condensation the water flows to the protrusion part driven by the vortex, and finally drips back into the cookware along the protrusion part. The curved groove surface and the protrusion part are set to appropriate positions according to the needs of use.

A cooking and draining system includes: a vessel including a bottom and an upstanding side wall forming an interior region of the vessel and an opening opposite the bottom of the vessel, the vessel further including: a heating element located in one of the bottom and the side wall; a valve located in one of the bottom and the side wall, the valve selectively controlling outflow of fluid from the interior region of the vessel; a lid selectively sealing the opening opposite the bottom of the vessel; and a base selectively coupled to the vessel and selectively causing the heating element to heat the interior region of the vessel.

A fluid pumping device is disclosed. The fluid pumping device includes a housing having a front end and a rear end, a fluid discharge opening in the front end of the housing, a pump assembly, a crank assembly rotatably connected to the pump assembly wherein the crank assembly operates the pump assembly, and a fluid storage reservoir connected to the gear housing from which fluid is drawn into the gear housing to be pumped through the fluid discharge opening.

A container with strainer divider is appointed to filter liquid from a food product to maintain freshness. The liquid strainer divider has a main body portion with a plurality of closely arranged apertures having small diameters. The body portion terminates at a perimeter with a perimeter rim. The perimeter rim and perimeter of the main body portion of the liquid strainer divider are adapted to be received and abut against walls of a container and the plurality of straining holes or apertures of the liquid strainer divider function to separate liquid to the bottom wall of the container. The liquid strainer divider is formed having a plurality of interconnected shallow peaks and valleys, wherein the peaks are formed as a convex arched curve with sloping walls terminating to valleys that are conversely concave arched curves so as to form an interconnected waved structure.

A field water purification system filter is described. The filter includes a water tight enclosure formed between two layers of a polymeric material, an inlet and an outlet are coupled to the water tight enclosure. A filter envelope including a quantity of filter media is inside the water tight enclosure. The water filter having a minimal thickness when not filled with water. The filter envelope is formed by a first set of bonded segments of the two layers of polymeric material. The filter can also include an outer channel having a first side formed by the water tight enclosure and a second side opposite from the first side. The second side can include a second set of bonded segments of the two layers of polymeric material interspersed with a set of nonbonded segments, the nonbonded segments defining openings in an intermittent barrier between the outer channel and the filter media.

Examples are disclosed herein that relate to a cooking system. One example provides a cooking system including a body supporting a cooking surface, a grease trap receptacle positioned within the body, the grease trap receptacle including an opening to an outside of the body, a grease drain located adjacent to the cooking surface, the grease drain opening into the grease trap receptacle such that the grease drain and the grease trap receptacle define a watertight passage for water to flow from the cooking surface to the opening, and a grease trap movably positioned within the opening of the grease trap receptacle.
