Abstract
Abstract A molding device having a hingedly connected base and cover. The base has an upper face with a recessed portion. An upstanding ridge completely surrounds such recess with a series of teeth along its upper edge. The cover has a lower face with a recessed portion. A closed ridge extends downwardly from the recessed portion and completely surrounds such portion. This downwardly extending ridge has a series of teeth extending completely along its lower edge. The teeth of the downwardly extending ridge and the teeth of the upstanding ridge mesh in cooperative engagement when the cover is closed over the base. When the cover is closed over the base the base and cover teeth are positioned for rolling, folding and cutting the foil of a lamination of foil, malleable material, and foil when a large enough lamination thereof is properly positioned between the teeth. Each recess contains an embossed design which is pressed into the upper and lower foil laminations when the cover is closed on the base.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
143 words
A molding device comprising a base, a cover hingedly attached to said base, said base having an upper face with a recess therein, a ridge extending upwardly from the exterior edges of said base recess, said base ridge extending above said base face and being an extension of the exterior edge of said base recess, teeth positioned along the entire upper edge of said base ridge, said cover having a lower face with a recess extending therein, a ridge extending downwardly from said cover recess, said cover ridge extending below said lower face and being an extension of the exterior edge of said cover recess, teeth positioned along the entire lower edge of said cover ridge, said base ridge teeth and said cover ridge teeth being so arranged that when said cover is closed over said base such teeth mesh in cooperative engagement.
Claim 2
Dependent Claim
143 words
A molding device comprising a base, a cover hingedly attached to said base, said base having an upper face with a recess therein, a ridge extending upwardly from the exterior edges of said base recess, said base ridge extending above said base face and being an extension of the exterior edge of said base recess, teeth positioned along the entire upper edge of said base ridge, said cover having a lower face with a recess extending therein, a ridge extending downwardly from said cover recess, said cover ridge extending below said lower face and being an extension of the exterior edge of said cover recess, teeth positioned along the entire lower edge of said cover ridge, said base ridge teeth and said cover ridge teeth being so arranged that when said cover is closed over said base such teeth mesh in cooperative engagement.
Claim 3
Dependent Claim
91 words
A molding device as called for in claim 1 wherein the raised portions of said base teeth adjacent the outside edge of said base ridge are further from the plane of said base face than the raised portions of said base teeth adjacent the inside edge of said base ridge, and the raised portions of said cover teeth adjacent the outside edge of said cover ridge are further from the plane of said cover face than the raised portions of said cover teeth adjacent the inside edge of said cover ridge.
Claim 4
Dependent Claim
55 words
A molding device as called for in claim 1 having a second ridge extending upwardly from and above the plane of said base face, said second upstanding ridge completely surrounding said base recess ridge and being positioned outwardly from said base recess ridge but being of the same general configuration as said base recess ridge.
Claim 5
Dependent Claim
50 words
A molding device as called for in claim 3 wherein the height of said second ridge above said plane is from approximately equal to one-half of the height of said base recess ridge above said plane to approximately equal to the height of said base recess ridge above said plane.
Claim 6
Dependent Claim
48 words
A molding device as called for in claim 1 wherein the width of said base teeth is equal to approximately one-half of the depth of said base recess and the width of the said cover teeth is equal to approximately one-half of the depth of said cover recess.
Claim 7
Dependent Claim
137 words
A molding device as called for in claim 1 wherein the raised portions of said base teeth adjacent the outside edge of said base ridge are further from the plane of said base face than the raised portions of said base teeth adjacent the inside edge of said base ridge, the raised portions of said cover teeth adjacent the outside edge of said cover ridge are further from the plane said cover face than the raised portions of said cover teeth adjacent the inside edge of said Cover ridge, and which has a second ridge extending upwardly from and above the plane of said base face, said second upstanding ridge completely surrounding said base recess ridge and being positioned outwardly from said base recess ridge but being of the same general configuration as said base recess ridge.
Claim 8
Dependent Claim
50 words
A molding device as called for in claim 6 wherein the height of said second ridge above said plane is from approximately equal to one-half of the height of said base recess ridge above said plane to approximately equal to the height of said base recess ridge above said plane.
Claim 9
Dependent Claim
48 words
A molding device as called for in claim 6 wherein the width of said base teeth is equal to approximately one-half of the depth of said base recess and the width of the said cover teeth is equal to approximately one-half of the depth of said cover recess.
Claim 10
Dependent Claim
89 words
A molding device as called for in claim 6 wherein the width of said base teeth is equal to approximately one-half of the depth of said base recess and the width of the said cover teeth is equal to approximately one-half of the depth of said cover recess, and the height of said second ridge above said plane is from approximately equal to one-half of the height of said base recess ridge above said plane to approximately equal to the height of said base recess ridge above said plane.
Claim 11
Dependent Claim
102 words
A molding device as called for in claim 9 wherein the surface connecting the raised portions of said base teeth adjacent the outside edge of said base ridge with their corresponding raised portions of said base teeth adjacent the inside edge of said base ridge is curved, the surface connecting the raised portions of said cover teeth adjacent the outside edge of said cover ridge with their corresponding raised portions of said cover teeth adjacent the inside edge of said cover ridge is curved, and the inside edge of said teeth are convex with respect to the outside edge of said teeth.
