Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
92 words
A collapsible container made of metal comprising: collapsible stepped walls which are formed by alternating substantially horizontal surfaces and substantially vertical surfaces, the width of said substantially horizontal surfaces of the stepped walls being smaller than that of said substantially vertical surfaces; connecting portions between said substantially horizontal and said substantially vertical surfaces being alternately angled and curved; whereby when the container is collapsed after being used with portions between said angled connecting portions and said curved connecting portions being bent, said curved connecting portions are moved successively into said vertical surfaces.
Claim 2
Dependent Claim
92 words
A collapsible container made of metal comprising: collapsible stepped walls which are formed by alternating substantially horizontal surfaces and substantially vertical surfaces, the width of said substantially horizontal surfaces of the stepped walls being smaller than that of said substantially vertical surfaces; connecting portions between said substantially horizontal and said substantially vertical surfaces being alternately angled and curved; whereby when the container is collapsed after being used with portions between said angled connecting portions and said curved connecting portions being bent, said curved connecting portions are moved successively into said vertical surfaces.
Claim 3
Dependent Claim
10 words
The collapsible container of claim 1, having a cone shape.
Claim 4
Dependent Claim
10 words
The collapsible container of claim 1, having a pyramid shape.
Claim 5
Dependent Claim
10 words
The collapsible container of claim 1, having a frusto-conical shape.
Claim 6
Dependent Claim
14 words
The collapsible container of claim 1, wherein the metal is aluminum or stainless steel.
Claim 7
Dependent Claim
134 words
A collapsible metal container comprising: collapsible stepped walls of substantially the same thickness which are formed by alternating substantially horizontal surfaces and substantially vertical surfaces, the width of said substantially horizontal surfaces of the stepped walls being smaller than that of said substantially vertical surfaces; connecting portions between said substantially horizontal and said substantially vertical surfaces being alternately angled and curved; said container including a top and a spaced bottom, said top being adapted to mate with a cover for the container and said bottom being stepped inwardly from said top; whereby when the container is collapsed after being used with portions between said angled connecting portions and said curved connecting portions being bent, said curved connecting portions are moved successively into said vertical surfaces to assume a V-shape in the fully collapsed position.
Claim 8
Dependent Claim
134 words
A collapsible metal container comprising: collapsible stepped walls of substantially the same thickness which are formed by alternating substantially horizontal surfaces and substantially vertical surfaces, the width of said substantially horizontal surfaces of the stepped walls being smaller than that of said substantially vertical surfaces; connecting portions between said substantially horizontal and said substantially vertical surfaces being alternately angled and curved; said container including a top and a spaced bottom, said top being adapted to mate with a cover for the container and said bottom being stepped inwardly from said top; whereby when the container is collapsed after being used with portions between said angled connecting portions and said curved connecting portions being bent, said curved connecting portions are moved successively into said vertical surfaces to assume a V-shape in the fully collapsed position.
Claim 9
Dependent Claim
113 words
A collapsible container made of metal comprising: collapsible stepped walls which are formed by alternating substantially horizontal surfaces and substantially vertical surfaces, the width of said substantially horizontal surfaces of the stepped walls being smaller than that of said substantially vertical surfaces; connecting portions between said substantially horizontal and said substantially vertical surfaces being alternately angled and curved, said width of the substantially horizontal surface being extremely small and said substantially horizontal surface forming only a part of the curved connecting portion; whereby when the container is collapsed with portions between said angled connecting portions and said curved connecting portions are bent, said curved connecting portions being moved successively into said vertical surfaces.
Claim 10
Dependent Claim
113 words
A collapsible container made of metal comprising: collapsible stepped walls which are formed by alternating substantially horizontal surfaces and substantially vertical surfaces, the width of said substantially horizontal surfaces of the stepped walls being smaller than that of said substantially vertical surfaces; connecting portions between said substantially horizontal and said substantially vertical surfaces being alternately angled and curved, said width of the substantially horizontal surface being extremely small and said substantially horizontal surface forming only a part of the curved connecting portion; whereby when the container is collapsed with portions between said angled connecting portions and said curved connecting portions are bent, said curved connecting portions being moved successively into said vertical surfaces.
