Abstract
A food pan cover for use with a food pan having a flange extending from the walls and substantially surrounding the periphery of the walls. A plurality of protuberances and depressions are formed on the underside of the flange; on the cover under and adjacent to the walls, and a plurality of dovetail members are formed on the periphery of the walls. An elastomeric seal is formed on the protuberances, and depressions and dovetails of a polyurethane having a usable temperature after molding of 212° fahrenheit and a hardness of 60 to 120 shore A, with a plurality of ribs, and terminates in a downwardly curved projection defining a groove around the periphery of the seal.
Claims23
A plastic food pan cover comprising:
- a cover having a top major surface;
- at least one upright wall surrounding said major surface;
- an elastomeric seal adhered to the exterior of said wall;
- a plurality of retention projections extending from said wall to mechanically enhance bonding between said wall and said seal;
- and,
- at least one rib forming a portion of said seal for sealing between said cover and a food pan.
The combination of a food pan and cover comprising:
- a food pan having side walls, a bottom, and a flange extending around the upper periphery of the walls;
- a cover having a major surface and side walls extending upwardly from said major surface;
- a plurality of protuberances and depressions formed on the outer region of said cover side walls;
- and,
- a seal molded to the edge region of said cover formed with a plurality of ribs substantially surrounding said seal wherein said seal fits into the interior of said pan to extend downwardly and flex inwardly.
A food pan cover comprising:
- a cover formed with a major upper surface with walls extending upwardly therefrom;
- a flange extending from the walls and substantially surrounding the periphery of said walls;
- a plurality of protuberances and depressions formed on the underside of said flange;
- a plurality of protuberances and depressions formed under said cover and adjacent to said walls;
- a plurality of dovetail members formed on the periphery of said walls;
- and,
- an elastomeric seal formed on said protuberances and
- depressions and dovetail members.
A food container cover and seal comprising:
- a cover formed with a major surface surrounded by an upstanding wall and terminating at its periphery with a flange;
- a plurality of protuberances extending from said wall with relieved portions therebetween;
- a seal bonded to said cover on said protuberances formed of an elastomeric material having a hardness of 60 to 120 shore A and a temperature resistance when in use after molding at or exceeding 212°;
- and,
- a plurality of ribs surrounding and formed on said seal.
