Abstract: Hot or Cold soup made fresh from scratch, can or concentrate is prepared in a suitable container and after its preparation is kept cool, blended and re-circulated for long term shelf life until a serving is requested. This serving volume of soup is automatically pumped and heated to serving temperature (hot soup) and served in a suitable container like a cup or a bowl. The entire system where the soup resides is always kept refrigerated. The only portion of the soup that is heated after its preparation is the one dispensed. If it is a soup that is served cold the heating prior to dispensing is by-passed.

Abstract: A method and apparatus to close boxes made out of aluminum foil like the ones used in supermarkets. The boxes are made to be closed by hand, manually crimping the open aluminum foil around the base against the edge of the lid. The apparatus is hand held and operated by rolling it around the edge of the open aluminum foil base. It will form the edge of the seal against the lid, thus closing the box. The result of this invention is an aluminum foil box sealer that safely and quickly seals the lid against the base of the aluminum foil base.
