Abstract
An overflow prevention container or a boiling container has a bottom member configured with an underside connector plate having a first portion in contact with and a second portion of various contours extending in a thermal separation from the external surface of the bottom member. A thermal gradient is created between first and second portions, thus forming thermally distinct sides of the cooking vessel, causing liquid in the vessel cavity to circulate with a horizontal convectional flow pattern, resulting in prevention of the liquid medium from spillage from the vessel cavity. Grooves on an internal surface of the bottom member terminate in a jump board to provide directional constraint to the liquid as it is being heated.
Claims21
An overflow prevention container containing a liquid medium being heated, comprising:
- a sidewall extending in a vertical direction;
- a bottom member having an internal surface contiguous the liquid medium contained within said container and an external surface, said bottom member joined to said sidewall in one piece formation at a peripheral joint area, wherein said external surface of said bottom member includes a first portion and a second portion, said bottom member being configured with an underside connector plate,
- wherein said underside connector plate has a first area integrally fixed to said first portion of said external surface of said bottom member and a second area positioned in vertical alignment with said second portion of said external surface of said bottom member, said second area of said underside connector plate extending in a horizontal direction in spaced apart relationship with said second portion of said external surface of said bottom member forming a horizontally directed slot or thermal isolation gap therebetween, wherein said horizontally directed slot or thermal isolation gap is formed in said underside connector plate to extend throughout only said second area of said underside connector plate for forming two distinct thermal zones of said liquid medium in said container whereby said liquid medium is convectively displaced in a circular contour within said container.
A spill-proof container, comprising:
- a bottom member having an internal surface and an external surface, and a peripheral joint area outlining said internal and external surfaces of said bottom member, wherein said external surface of said bottom member has a first portion and a second portion bordering with one another, and wherein said bottom member is configured with an underside connector plate,
- wherein said underside connector plate has a first area integrally secured to said first portion of said external surface of said bottom member and a second area positioned in vertical alignment with said second portion of said external surface of said bottom member, said second area of said underside connector plate extending horizontally in a spaced apart relationship with and in a thermal separation from said second portion of said external surface of said bottom member to define a horizontally directed slot or thermal isolation gap therebetween, wherein said horizontally directed slot or thermal isolation gap is formed in said underside connector plate to extend throughout only said second area of said underside connector plate for forming two distinct thermal zones of said liquid medium in said container whereby said liquid medium is convectively displaced in a circular contour within said container;
- and
- an array of grooves fabricated on said internal surface of said bottom member, said grooves extending substantially in parallel to one another between respective portions of said peripheral joint area of said bottom member with a plurality of inter-groove channels formed between adjacent grooves to provide a directional flow of the liquid medium along said inter-groove channels within a vessel cavity defined by said internal surface of said bottom member.

A spill-proof container, comprising:
- a bottom member having an internal surface and an external surface, and a peripheral joint outlining said internal and external surfaces of said bottom member, wherein said external surface of said bottom member has a first portion and a second portion bordering with one another, and wherein said bottom member is configured with an underside connector plate,
- wherein said underside connector plate has a first area integrally secured to said first portion of said external surface of said bottom member and a second area positioned in vertical alignment with said second portion of said external surface of said bottom member, said second area of said underside connector plate extending horizontally in a spaced apart relationship with and in a thermal separation from said second portion of said external surface of said bottom member to define a horizontally directed slot or thermal isolation gap therebetween, wherein said horizontally directed slot or thermal isolation gap is formed in said underside connector plate to extend throughout only said second area of said underside connector plate for forming two distinct thermal zones of said liquid medium in said container whereby said liquid medium is convectively displaced in a circular contour within said container, and
- wherein a contour of said second portion of said external surface of said bottom member is selected from a group including a straight, angled, semi-circle, crescent, concave-convex contours, and a combination thereof.
