Door
First Claim
1. A molded door comprising a single unitary piece of hot molded integral thermosetting polymeric material forming a generally polygonal frame member defined by a front wall of a substantially polygonal configuration disposed substantially transverse to a peripheral wall substantially bordering said front wall, said thermosetting polymeric material being one of sheet molding compound (SMC) and bulk molding compound (BMC), a piece of tempered glass substantially closing an opening defined by an innermost heat and pressure extruded edge portion of said front wall, said glass piece having a peripheral edge, said glass piece peripheral edge being encapsulated by and in sandwiched relationship between opposite side portions of said front wall innermost heat and pressure extruded edge portion, and said front wall having an integrally molded handle located between said piece of glass and said peripheral wall.

Abstract
A peripherally encapsulated product, such as an oven door outer shell, is molded in accordance with this invention by placing a piece of glass between mold clamping portions of relatively movable closed bodies when the latter are in an open position. Preferably both bodies are heated and thermosetting polymeric material (SMC or BMC) is placed upon selected areas of one of the mold bodies within and about an area corresponding to an annular mold cavity and outboard of a peripheral edge of a piece of glass. The glass is clamped between mold clamping portions of the mold bodies which are then progressively closed creating compression forces which extrude the thermosetting polymeric material into the annular cavity and into complete encapsulation of the continuous peripheral edge of the piece of glass. The handle can be integrally molded during the molding process.

- 8. A door comprising a door frame, said door frame including a frame member defined by a polymeric/copolymeric synthetic plastic molded material front wall having an inner peripheral edge portion, a piece of tempered glass substantially closing an opening defined by said inner peripheral edge portion of said front wall, said glass piece having a peripheral edge, said glass piece peripheral edge and said inner peripheral edge portion being in substantially bordering relationship to each other, a handle formed in situ in said front wall outboard of said inner peripheral edge portion during the molding of said frame member, said handle including a finger-receiving opening opening through a handle forming wall portion of said front wall, and said finger-receiving opening being defined by an in situ molded edge of said in situ molded front wall handle forming wall portion.
