Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
168 words
A radiation resistant container, said container fabricated from layers of sheets laminated together to form a single laminate, one of said sheets being impervious to radiation of the x-ray type, a first plastic sheet laminated to one side of said sheet of radiation impervious material, a second plastic sheet laminated to the other side of said sheet of radiation impervious material, said single laminate having first and second spaced apart ends, a top and a bottom, said single laminate being folded so that at least an inch of the first plastic sheet at the ends of said single laminate abut each other, said abutting ends of said first plastic sheet being sealed together, the bottoms of said first plastic sheet being in a sealed abutting relationship for at least an inch, and holding means for removably holding the top folded over by at least an inch and contiguous to the rest of the laminate thereby forming a bag that can be closed to prevent radiation from entering therein.
Claim 2
Dependent Claim
168 words
A radiation resistant container, said container fabricated from layers of sheets laminated together to form a single laminate, one of said sheets being impervious to radiation of the x-ray type, a first plastic sheet laminated to one side of said sheet of radiation impervious material, a second plastic sheet laminated to the other side of said sheet of radiation impervious material, said single laminate having first and second spaced apart ends, a top and a bottom, said single laminate being folded so that at least an inch of the first plastic sheet at the ends of said single laminate abut each other, said abutting ends of said first plastic sheet being sealed together, the bottoms of said first plastic sheet being in a sealed abutting relationship for at least an inch, and holding means for removably holding the top folded over by at least an inch and contiguous to the rest of the laminate thereby forming a bag that can be closed to prevent radiation from entering therein.
Claim 3
Dependent Claim
14 words
The radiation resistant container of claim 1 wherein said holding means comprises wire tabs.
Claim 4
Dependent Claim
29 words
The radiation resistant container of claim 1 wherein said radiation impervious material consists of lead foil, and wherein the first plastic sheet is the interior lining of the bag.
Claim 5
Dependent Claim
24 words
The radiation resistant container of claim 3 wherein said first plastic sheet comprises black polyethylene, and wherein the second plastic sheet comprises white polyester.
Claim 6
Dependent Claim
30 words
The radiation resistant container of claim 4 wherein said polyethylene sheet is 1/2,000 to 1/5,000 of an inch thick and said polyester is 1/1,000 to 1/2,000 of an inch thick.
Claim 7
Dependent Claim
102 words
A radiation resistant container, said container comprising a piece of luggage, the lining of said luggage including a laminate, said laminate fabricated from three layers of sheets of material laminated together, the middle layer being a sheet of lead foil, a first layer on one side of lead foil being a sheet of black polyethylene, a second layer on the other side of said lead foil being a sheet of white polyester, said luggage container having a cover and a main body section each lined with the laminate, and said cover overlapping onto the main body section by at least an inch.
Claim 8
Dependent Claim
102 words
A radiation resistant container, said container comprising a piece of luggage, the lining of said luggage including a laminate, said laminate fabricated from three layers of sheets of material laminated together, the middle layer being a sheet of lead foil, a first layer on one side of lead foil being a sheet of black polyethylene, a second layer on the other side of said lead foil being a sheet of white polyester, said luggage container having a cover and a main body section each lined with the laminate, and said cover overlapping onto the main body section by at least an inch.
Claim 9
Independent Claim
139 words
A method of fabricating a radiation resistant container from a laminate, the method of combining the steps of laminating a black polyethylene sheet to one side of a lead foil sheet, laminating the other side with a white polyester sheet to make a laminate, said laminate being spread out with the white side down and the black side up, said laminate folded so that the black ends thereof abut each other by at least a 1 inch section, sealing together the ends at the at least 1 inch abutting section, sealing two sides of the open bottom together so that there is at least a 1 inch sealed abutting section of the polyethylene closing the open bottom, and the open top being folded over at least an inch to fabricate a container for use in protecting radiation susceptible material.
Claim 10
Independent Claim
139 words
A method of fabricating a radiation resistant container from a laminate, the method of combining the steps of laminating a black polyethylene sheet to one side of a lead foil sheet, laminating the other side with a white polyester sheet to make a laminate, said laminate being spread out with the white side down and the black side up, said laminate folded so that the black ends thereof abut each other by at least a 1 inch section, sealing together the ends at the at least 1 inch abutting section, sealing two sides of the open bottom together so that there is at least a 1 inch sealed abutting section of the polyethylene closing the open bottom, and the open top being folded over at least an inch to fabricate a container for use in protecting radiation susceptible material.
