Abstract
Abstract A contoured bed sheet made from a single, substantially rectangular expanse of flexible material by folding over flaps adjacent opposite edges to form a rectangular article having double-ply edge margins. An outer corner portion of an edge margin thus formed is folded over against remainder portions of such edge margin, along a line extending diagonally of the fold line for the flap in such edge margin. The corner is adhesively secured to the underlying remainder portions. When the flaps are lifted from the central expanse of the sheet, they form side panels, and the end of the expanse which has the folded over corner portions forms an end panel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
107 words
A contoured bed sheet comprising a substantially rectangular expanse of flexible material having elongated narrow flaps adjacent opposite terminal edges of the expanse folded over a common face of the expanse along fold lines extending substantially parallel to said terminal edges producing a pair of opposed double-ply edge margins, at least one corner of the bed sheet being formed by folding an outer corner portion of one of said edge margins over against remainder portions of said edge margin along a line extending diagonally of the fold line in said edge margin, said corner portion being adhesively bonded to the underlying remainder portions of said edge margin.
Claim 2
Dependent Claim
107 words
A contoured bed sheet comprising a substantially rectangular expanse of flexible material having elongated narrow flaps adjacent opposite terminal edges of the expanse folded over a common face of the expanse along fold lines extending substantially parallel to said terminal edges producing a pair of opposed double-ply edge margins, at least one corner of the bed sheet being formed by folding an outer corner portion of one of said edge margins over against remainder portions of said edge margin along a line extending diagonally of the fold line in said edge margin, said corner portion being adhesively bonded to the underlying remainder portions of said edge margin.
Claim 3
Dependent Claim
27 words
The sheet of claim 1, wherein the diagonal line along which said corner portion is folded extends at substantially a 45* angle relative to said fold line.
Claim 4
Dependent Claim
39 words
The sheet of claim 1, wherein an edge in said folded over corner portion extends substantially parallel to said fold line and is spaced toward said fold line from the terminal edge of the flap in said edge margin.
Claim 5
Dependent Claim
43 words
The sheet of claim 1, wherein an edge in said fold-ed over corner portion extends substantially normal to said fold line, and an adhesive deposit extending substantially parallel to said edge bonds the corner portion to underlying remainder portions of the edge margin.
Claim 6
Dependent Claim
127 words
A contoured bed sheet formed from a single substantially rectangular sheet of flexible material comprising, in operative position, a substantially rectangular central expanse, side panels depending from opposite sides of said central expanse, and at least one end panel depending from an end of said central expanse; at least one of said side panels having an end tab underlying said end panel and joined to the side panel through a crease which is normal to said centRal expanse; another tab lying between the end panel and the first-mentioned tab which is joined to the end panel through a crease parallel and adjacent the first-mentioned crease; said tabs being integrally joined along a line inclining relative to said central expanse; and means adhesively securing the two tabs together.
Claim 7
Dependent Claim
127 words
A contoured bed sheet formed from a single substantially rectangular sheet of flexible material comprising, in operative position, a substantially rectangular central expanse, side panels depending from opposite sides of said central expanse, and at least one end panel depending from an end of said central expanse; at least one of said side panels having an end tab underlying said end panel and joined to the side panel through a crease which is normal to said centRal expanse; another tab lying between the end panel and the first-mentioned tab which is joined to the end panel through a crease parallel and adjacent the first-mentioned crease; said tabs being integrally joined along a line inclining relative to said central expanse; and means adhesively securing the two tabs together.
Claim 8
Dependent Claim
17 words
The sheet of claim 5, wherein a side panel has a greater width than said end panel.
Claim 9
Dependent Claim
25 words
The sheet of claim 5, wherein said second-mentioned tab is joined to said first-mentioned tab by an adhesive line extending adjacent and paralleling said creases.
