Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
94 words
A battery container fabricated from a thermally deformable material, said battery comprising an outside wall having an interior and exterior surface and including a port, a terminal extending through said port to provide electrical conduction between the interior and exterior of said container, said terminal having a unitary body formed by casting from molten metal directly in place within said port, said unitary body including an integral inside flared end portion which extends in surrounding relation to said port and in fluid tight sealing relation directly with the interior surface of said outside wall.
Claim 2
Dependent Claim
94 words
A battery container fabricated from a thermally deformable material, said battery comprising an outside wall having an interior and exterior surface and including a port, a terminal extending through said port to provide electrical conduction between the interior and exterior of said container, said terminal having a unitary body formed by casting from molten metal directly in place within said port, said unitary body including an integral inside flared end portion which extends in surrounding relation to said port and in fluid tight sealing relation directly with the interior surface of said outside wall.
Claim 3
Dependent Claim
39 words
The battery container of claim 1 wherein said terminal includes an integral outside flared end portion which extends in surrounding relation to said port and in fluid tight sealing relation directly with the exterior surface of said outside wall.
Claim 4
Dependent Claim
21 words
The battery container of claim 1 wherein the cast terminal is substantially free of entrapped air to provide desirable electrical properties.
Claim 5
Dependent Claim
42 words
The battery container of claim 1 wherein said outside wall comprises an integral boss structure which includes a circular ring portion extending outwardly from the wall and defining said port within and through which the terminal is cast directly from molten metal.
Claim 6
Dependent Claim
49 words
The battery container of claim 4 wherein the circular ring portion of the boss structure comprises a plurality of ring projections defining hollow concentric spaces therebetween which contains conforming projecting portions of the cast terminal to anchor the solid terminal in a locked position within and through the wall.
Claim 7
Dependent Claim
46 words
The battery container of claim 4 wherein the port is provided with a plurality of lugs disposed about the internal periphery of the port which extends radially inwardly into the solid cast terminal to anchor the terminal in a locked position within and through the wall.
Claim 8
Dependent Claim
30 words
The battery container of claim 1 wherein an internally threaded metal insert is cast within the terminal to provide threadable means for making an external mechanical connection to the terminal.
Claim 9
Dependent Claim
29 words
The battery container of claim 7 wherein the terminal metal contains lead and the metal insert is composed of a metal having greater wear resistance than the terminal metal.
Claim 10
Dependent Claim
54 words
The battery container of claim 1 wherein said body of said cast terminal is of L-shaped cross-sectional configuration having one leg extending horizontally through said outside wall and the integral inside flared end portion forming the other leg extending vertically upwardly and having an exposed surface for making electrical contact interior to the container.
Claim 11
Dependent Claim
14 words
The battery container of claim 1 wherein the thermally deformable material is a polyolefin.
Claim 12
Dependent Claim
11 words
The battery container of claim 10 wherein the polyolefin is polypropylene.
Claim 13
Dependent Claim
75 words
A metal terminal of a battery container for providing electrical conduction through a port formed in the side wall of the battery container, said terminal comprising a unitary body formed by casting from molten metal directly in place within said port, said unitary body including an integral inside flared end portion adapted to extend in surrounding relation to said port and in fluid tight sealing relation directly with the interior surface of the side wall.
Claim 14
Dependent Claim
75 words
A metal terminal of a battery container for providing electrical conduction through a port formed in the side wall of the battery container, said terminal comprising a unitary body formed by casting from molten metal directly in place within said port, said unitary body including an integral inside flared end portion adapted to extend in surrounding relation to said port and in fluid tight sealing relation directly with the interior surface of the side wall.
Claim 15
Dependent Claim
42 words
The terminal of claim 12 wherein said terminal also includes an integral outside flared end portion which is adapted to extend in surrounding relation to said port and in fluid tight sealing relation directly with the exterior surface of the side wall.
Claim 16
Dependent Claim
58 words
The terminal of claim 13 wherein said unitary body is of L-shaped cross-sectional configuration having one leg extending horizontally through the side wall and the integral inside flared end portion adjacent the interior surface of the side wall forming the other leg extending vertically upwardly and having an exposed surface for making an electrical contact interior the container.
Claim 17
Dependent Claim
58 words
The terminal of claim 13 wherein the integral outside flared end portion adjacent the exterior surface of the side wall has a plurality of inwardly projecting portions which mate and conform with a corresponding irregular contour of the exterior surface of the container side wall to lock the cast terminal in place within and through the side wall.
Claim 18
Dependent Claim
20 words
The terminal of claim 12 wherein the cast terminal is substantially free of entrapped air to provide desirable electrical properties.
Claim 19
Dependent Claim
29 words
The terminal of claim 1 wherein an internally threaded metal insert is cast within the terminal to provide threadable means for making an external mechanical connection to the terminal.
Claim 20
Dependent Claim
28 words
The terminal of claim 17 wherein the terminal metal contains lead and the metal insert is composed of a metal having greater wear resistance then the terminal metal.
