13. The cooktop, hob top or the like as defined in claim 1 wherein said cooktop panel peripheral edge portion, frame and peripheral securing means each have an uppermost surface, and said uppermost surfaces collectively define a substantially smooth uppermost surface of said cooktop.

14. The cooktop, hob top or the like as defined in claim 2 including means between said cooktop panel peripheral edge portion and said peripheral securing means for bondingly adhering said cooktop panel peripheral edge portion and said peripheral securing means to each other.

15. The cooktop, hob top or the like as defined in claim 2 wherein said integral injection molded attaching means includes a plurality of spaced projecting fasteners for fastening said cooktop to a support.

16. The cooktop, hob top or the like as defined in claim 2 wherein said integral injection molded attaching means includes a plurality of spaced projecting fasteners for fastening said cooktop to a horizontal support.

17. The cooktop, hob top or the like as defined in claim 2 wherein said frame includes a vertical leg having a plurality of openings therein, and said injection molded peripheral securing means is n embracing relationship to said leg and in spanning relationship through said plurality of openings.

18. The cooktop, hob top or the like as defined in claim 2 wherein said injection molded peripheral securing means includes a peripheral leg portion sandwiched between an outermost peripheral edge of said cooktop panel peripheral edge portion and an innermost peripheral edge of said frame.

19. The cooktop, hob top or the like as defined in claim 2 wherein said cooktop panel peripheral edge portion, frame and peripheral securing means each have an uppermost surface, and said uppermost surfaces collectively define a substantially smooth uppermost surface of said cooktop.

20. The cooktop, hob top or the like as defined in claim 2 wherein said integral injection molded attaching means depends substantially normal to a plane through said cooktop panel.

21. The cooktop, hob top or the like as defined in claim 20 including means between said cooktop panel peripheral edge portion and said peripheral securing means for bondingly adhering said cooktop panel peripheral edge portion and said peripheral securing means to each other.
