Abstract
Abstract A one piece bib having slits for providing a head opening and having a pocket for catching spilled food and the like is made from a single sheet. The lower longitudinal edges of a generally oblong sheet are cut away on the bias; the sheet is folded on the longitudinal center line and the lower edges are sealed together. When the sheet is unfolded, a V-shaped pocket has been formed to stand open to receive any food that has been spilled by the wearer. In the method of making the bib slits may be cut in an elongated sheet adjacent its upper edge to define a head opening. In the same operation, longitudinal edge portions or corners at the lower end are cut off on a bias, and folds are formed at the longitudinal center line and from the longitudinal center line to opposite edges of the bib at the upper severing points where the material is cut away. The sheet is then folded along the center line and the lower edges are sealed. When the bib is unfolded a V-shaped pocket has been formed.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
71 words
In a one piece disposable bib, a sheet having a lateral edge at an upper end of the bib and two longitudinal edges extending downwardly therefrom, a neck opening adjacently spaced from said lateral edge and between said longitudinal edges, the improvement comprising: a pocket at a lower end of the sheet opposite said upper end, said pocket being open toward said upper end and being V-shaped widthwise along its bottom.
Claim 2
Dependent Claim
71 words
In a one piece disposable bib, a sheet having a lateral edge at an upper end of the bib and two longitudinal edges extending downwardly therefrom, a neck opening adjacently spaced from said lateral edge and between said longitudinal edges, the improvement comprising: a pocket at a lower end of the sheet opposite said upper end, said pocket being open toward said upper end and being V-shaped widthwise along its bottom.
Claim 3
Dependent Claim
19 words
The invention according to claim 1 in which: said V-shaped pocket bottom defines said lower end of said sheet.
Claim 4
Dependent Claim
43 words
The invention according to claim 2 in which: said pocket has a front face formed of two triangles having a common side, said triangles each having a lower side formed by a leg of the V defining the lower end of the sheet.
Claim 5
Dependent Claim
90 words
The invention according to claim 3 in which: said common side of said triangle is defined by two joined sealed edges of said sheet, said sealed edges having been two portions of a lower lateral edge of said sheet, respective area portions of said sheet bounded by each lower lateral edge portion and respective adjacent longitudinal edges having been folded upwardly in the direction from said lower lateral edge and inwardly in the direction from the respective adjacent longitudinal edge to position said sealed edges to form said common side.
Claim 6
Dependent Claim
23 words
The invention according to claim 4 in which: the upper sides of said triangles each form an obtuse angle with said common side.
Claim 7
Dependent Claim
23 words
The invention according to claim 5 in which: before folding each of said lower edge portions comprised half of said lower lateral edge.
Claim 8
Dependent Claim
19 words
The invention according to claim 2 in which: upper edges of said pocket at said opening form a V.
Claim 9
Dependent Claim
49 words
The invention according to claim 1 in which: said head opening is defined by two spaced arced slits and a straight line slit extending therebetween, said straight line slit being in approximate alignment with the centers of said arced slits, said straight line slit extending in the lateral direction.
Claim 10
Dependent Claim
21 words
The invention according to claim 8 in which: said arced slits have a plurality of relatively short slits at their ends.
Claim 11
Dependent Claim
23 words
The invention according to claim 8 in which: a line of perforations extends from said straight line slit to the upper lateral edge.
Claim 12
Dependent Claim
26 words
The invention according to claim 1 in which: said head opening is defined by a semicircular slit having its concave edge generally facing said lower end.
Claim 13
Independent Claim
98 words
A method of making a one piece disposable bib comprising: cutting slits in a generally elongated sheet adjacent an upper lateral end to define a head opening, cutting longitudinal edge portions from the sheet to remove lower end corners, forming a longitudinally extending central fold line in the sheet, forming fold lines extending from the central fold line at the lower end to the longitudinal edges at the upper severing points of the cutaway longitudinal edge portions, folding said sheet along said center fold line to enclose the front of the sheet, and sealing the lower edges together.
Claim 14
Independent Claim
98 words
A method of making a one piece disposable bib comprising: cutting slits in a generally elongated sheet adjacent an upper lateral end to define a head opening, cutting longitudinal edge portions from the sheet to remove lower end corners, forming a longitudinally extending central fold line in the sheet, forming fold lines extending from the central fold line at the lower end to the longitudinal edges at the upper severing points of the cutaway longitudinal edge portions, folding said sheet along said center fold line to enclose the front of the sheet, and sealing the lower edges together.
Claim 15
Dependent Claim
25 words
A method according to claim 12 including: cutting said sheets from a roll of sheet material at the same time said other cuts are made.
Claim 16
Dependent Claim
27 words
A method according to claim 12 including: perforating sheet material coming off a roll to define individual elongated sheets at the same time said cuts are made.
Claim 17
Dependent Claim
32 words
A method according to claim 12 in which: said longitudinal edge portions are right triangles having relatively long right angle legs in the longitudinal direction and short bases in the lateral direction.
