Abstract
Abstract A plurality of disposable bibs formed consecutively on sheet material and having a perforated tear line forming each bib, and also forming a pair of ties which are formed between the perforations of the bib and the perforated tear line to be placed around the neck of a wearer and tied behind. Each of the perforated tear lines extends outwardly from a centrally located nadir toward the outer edges at an angle less than 40* between the outer edges and the end of the perforated tear line. The distance between adjacent nadirs is 1.5-3 times the depth of the perforated tear line, and the width of the bib is 1-3 times the depth of the same perforated tear line.

Total Claims: 5
Claim 1
Independent Claim
189 words
A plurality of disposable bibs comprising a roll of disposable sheet material, a plurality of sections successively formed in said sheet material each said section being defined by parallel sIdes constituting the outer edges of said sheet material, the top and bottom of each section each being defined by mutually identically-shaped convex curved perforated tear lines, each perforated tear line having its nadir centrally located between said outer edges, each said perforated tear line extending outwardly toward said outer edges and intersecting said outer edges at an angle less than 40*, the distance between adjacent nadirs being 1.5 to 3 times the depth of said perforated tear line, and the width of said bibs being 1 to 3 times the depth of said perforated line, tie means formed on said sheet material between each said outer edge and said perforated tear line and being shaped to conform to be tied around the neck of the wearer, bib means formed on said sheet material within and partially bounded at the bottom by said perforated tear line, whereby individual disposable bibs are removable from said roll by tearing said perforated line.
