Abstract
Abstract This invention relates to edible pies that are baked in plates and then cut into segmental portions and removed from the plate as individual servings, provision being made for gaining access to and to loosen each portion of pie in order to avoid mutilation thereto, and involving lines of weakening extending radially of the plate so as to define segments and specifically through the side and rim of the plate, whereby segmental sections of the side and rim are hinged and depressable for exposing cut portions of pie and for having a lever action that lifts and loosens the pie, thereby facilitating extraction of pie portions from the plate without mutilation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
127 words
A round pie plate facilitating the removal of cut portions of edible pie and including: a flat disc-shaped bottom and an upstanding outwardly flared side joined rigidly to the perimeter of the bottom and for the containment of the whole pie, and at least one pair of spaced lines of weakening emanating from the point of joinder between the bottom and side and extending upwardly and coextensively of the side, the pie plate being made of a bendable material and subject to deliberate separation along said lines of weakening upon manual depression of the side section therebetween and revolvement thereof on a hinge line extending between the said lines of weakening at said points of joinder, whereby the depressed side section exposes a portion of the pie.
Claim 2
Dependent Claim
127 words
A round pie plate facilitating the removal of cut portions of edible pie and including: a flat disc-shaped bottom and an upstanding outwardly flared side joined rigidly to the perimeter of the bottom and for the containment of the whole pie, and at least one pair of spaced lines of weakening emanating from the point of joinder between the bottom and side and extending upwardly and coextensively of the side, the pie plate being made of a bendable material and subject to deliberate separation along said lines of weakening upon manual depression of the side section therebetween and revolvement thereof on a hinge line extending between the said lines of weakening at said points of joinder, whereby the depressed side section exposes a portion of the pie.
Claim 3
Dependent Claim
44 words
The pie plate with a depressible side section as set forth in claim 1 and wherein the side has a rolled edge that is notched at each line of weakening to start separation of the side section from the remaining parts of the plate.
Claim 4
Dependent Claim
152 words
A round pie plate for loosening and facilitating the removal of cut portions of edible pie and including; a flat disc-shaped bottom and an upstanding side joined rigidly to the periphery of the bottom and for containment of the whole pie, and at least one pair of circumferentially spaced lines of weakening emanating from the point of joinder between the bottom and side and extending upwardly and coextensively of the side, the pie plate being made of a bendable material subject to deliberate separation along said lines of weakening upon manual depression of the side therebetween, there being a hinge extending on a chord line between the said lines of weakening at said points of joinder, whereby the depressed side section revolves and bends the chord area from the plane of the bottom and downwardly to act as a lever lifting up the area of the bottom radially inward of the same.
Claim 5
Dependent Claim
152 words
A round pie plate for loosening and facilitating the removal of cut portions of edible pie and including; a flat disc-shaped bottom and an upstanding side joined rigidly to the periphery of the bottom and for containment of the whole pie, and at least one pair of circumferentially spaced lines of weakening emanating from the point of joinder between the bottom and side and extending upwardly and coextensively of the side, the pie plate being made of a bendable material subject to deliberate separation along said lines of weakening upon manual depression of the side therebetween, there being a hinge extending on a chord line between the said lines of weakening at said points of joinder, whereby the depressed side section revolves and bends the chord area from the plane of the bottom and downwardly to act as a lever lifting up the area of the bottom radially inward of the same.
Claim 6
Dependent Claim
46 words
The pie plate with a depressible and revolvable side section as set forth in claim 3 and wherein the side has a rolled edge that is notched at each line of weakening to start separation of the side section from the remaining parts of the plate.
