Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
167 words
A prefolded diaper formed from an elongate flat rectangular pad of absorbent material, said pad comprising narrow unfolded end portions at each end and a major folded mid portion between said end portions, the end portions of said pad defining a bodyencircling waist band and the mid portion of said pad comprising a multiplicity of adjoining triangular sections folded to provide a main pocket depending from the approximate center point of said mid portion and two secondary pockets laterally disposed on each side of said main pocket, said main pocket being formed at the juncture of six centrally disposed triangular sections, and each of said secondary pockets being formed at the juncture of four triangular sections disposed at each side of said pad, said centrally disposed main pocket being substantially deeper than each of said side pockets, and a portion of the outer faces of the two adjoining triangular sections on each side of the pad which form the outer edge of the diaper being adhesively joined.
Claim 2
Dependent Claim
167 words
A prefolded diaper formed from an elongate flat rectangular pad of absorbent material, said pad comprising narrow unfolded end portions at each end and a major folded mid portion between said end portions, the end portions of said pad defining a bodyencircling waist band and the mid portion of said pad comprising a multiplicity of adjoining triangular sections folded to provide a main pocket depending from the approximate center point of said mid portion and two secondary pockets laterally disposed on each side of said main pocket, said main pocket being formed at the juncture of six centrally disposed triangular sections, and each of said secondary pockets being formed at the juncture of four triangular sections disposed at each side of said pad, said centrally disposed main pocket being substantially deeper than each of said side pockets, and a portion of the outer faces of the two adjoining triangular sections on each side of the pad which form the outer edge of the diaper being adhesively joined.
Claim 3
Dependent Claim
37 words
The diaper of claim 1 wherein an inside portion of the centrally disposed main pocket is adhesively joined to each of the adjoining faces of the inner two triangular sections disposed at each side of said pad.
Claim 4
Dependent Claim
456 words
A folded diaper construction formed from an elongate flat rectangle of absorbent material comprised of narrow transverse waist-band portions disposed at both ends and a substantially square central portion; said central portion being divided into four adjoining triangular segments comprising isosceles triangles with two of the triangle bases horizontally disposed and the other two bases vertically disposed; the apices of all four of said isosceles triangles meeting at the approximate geometric center of said square central portion; each of the two triangles with the vertically disposed bases being further divided into two equal right-angled triangles by a horizontal line which passes through the meeting point of said apices and intercepts the vertically disposed bases; each of said right-angled triangles being further segmented into three adjoining triangles by lines which start at each of the peaks of said right-angled triangles adjacent the diaper edges and intercept said horizontal line; said segmenting lines dividing each of said right-angled triangles into a narrower right-angled triangle bordering on said vertically disposed base, a first obtuse-angled triangle adjoining said narrower right-angled triangle, and a second more obtuse-angled triangle adjoining said first obtuse-angled triangle; said horizontal line on each side of the diaper being a common base to two of said narrower right-angled triangles of equal dimension, two of said first obtuse-angled triangles of equal dimension, and two of said second obtuse-angled triangles of equal dimension; said horizontal line and the longest dimension line of each triangle into which said right-angled triangle is divided comPrising fold lines on which said diaper is folded to form said folded diaper construction; said folds comprising a first inward fold on each of the longest dimension lines of said second obtuse-angled triangles and a cooperating outward fold on the line forming the base of said second obtuse-angled triangles, an outward fold on each of the longest dimension lines of said first obtuse-angled triangles and a cooperating inward fold on the line forming the base of said first obtuse-angled triangles, and a second inward fold on each of the longest dimension lines of said narrower right-angled triangles and an outward fold on the line forming the base of said narrower right-angled triangles; the folds in said diaper defining a central main pocket bottoming at the fold juncture located at the apices of said isosceles triangle segments, and supplementary side pockets laterally disposed on either side of said central pocket; the bottom of said side pockets being disposed at the fold where the long dimension lines of each of the two adjoining narrower right-angled triangles meet at said horizontal line, the contracting faces of said narrower right-angled triangular segments being adhered together in an area close to the outward fold forming the base of said narrower, right-angled triangles.
Claim 5
Dependent Claim
456 words
A folded diaper construction formed from an elongate flat rectangle of absorbent material comprised of narrow transverse waist-band portions disposed at both ends and a substantially square central portion; said central portion being divided into four adjoining triangular segments comprising isosceles triangles with two of the triangle bases horizontally disposed and the other two bases vertically disposed; the apices of all four of said isosceles triangles meeting at the approximate geometric center of said square central portion; each of the two triangles with the vertically disposed bases being further divided into two equal right-angled triangles by a horizontal line which passes through the meeting point of said apices and intercepts the vertically disposed bases; each of said right-angled triangles being further segmented into three adjoining triangles by lines which start at each of the peaks of said right-angled triangles adjacent the diaper edges and intercept said horizontal line; said segmenting lines dividing each of said right-angled triangles into a narrower right-angled triangle bordering on said vertically disposed base, a first obtuse-angled triangle adjoining said narrower right-angled triangle, and a second more obtuse-angled triangle adjoining said first obtuse-angled triangle; said horizontal line on each side of the diaper being a common base to two of said narrower right-angled triangles of equal dimension, two of said first obtuse-angled triangles of equal dimension, and two of said second obtuse-angled triangles of equal dimension; said horizontal line and the longest dimension line of each triangle into which said right-angled triangle is divided comPrising fold lines on which said diaper is folded to form said folded diaper construction; said folds comprising a first inward fold on each of the longest dimension lines of said second obtuse-angled triangles and a cooperating outward fold on the line forming the base of said second obtuse-angled triangles, an outward fold on each of the longest dimension lines of said first obtuse-angled triangles and a cooperating inward fold on the line forming the base of said first obtuse-angled triangles, and a second inward fold on each of the longest dimension lines of said narrower right-angled triangles and an outward fold on the line forming the base of said narrower right-angled triangles; the folds in said diaper defining a central main pocket bottoming at the fold juncture located at the apices of said isosceles triangle segments, and supplementary side pockets laterally disposed on either side of said central pocket; the bottom of said side pockets being disposed at the fold where the long dimension lines of each of the two adjoining narrower right-angled triangles meet at said horizontal line, the contracting faces of said narrower right-angled triangular segments being adhered together in an area close to the outward fold forming the base of said narrower, right-angled triangles.
Claim 6
Dependent Claim
36 words
The diaper of claim 3 in which a portion of the face of each of said narrower right-angled triangular segments is adhered to a portion of the face of its respective adjoining second obtuse-angled triangular segment.
