Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
A diaper of oblong configuration comprising an outer layer of a nonwoven fibrous material with the fibers oriented longitudinally of the diaper, a further outer layer of a material of high wet strength, and an intermediate layer sandwiched between the outer layers and forming fore and rear absorption portions separated by a border region, one of said portions being thicker than another thereof to form an absorption cushion, and said border region being constructed as a barrier for liquid tending to pass in the absorption material from one of said portions to the other, said barrier being formed by a strip of compressed absorption material extending continuously from one longitudinal edge of the diaper to the other.
Claim 2
Dependent Claim
117 words
A diaper of oblong configuration comprising an outer layer of a nonwoven fibrous material with the fibers oriented longitudinally of the diaper, a further outer layer of a material of high wet strength, and an intermediate layer sandwiched between the outer layers and forming fore and rear absorption portions separated by a border region, one of said portions being thicker than another thereof to form an absorption cushion, and said border region being constructed as a barrier for liquid tending to pass in the absorption material from one of said portions to the other, said barrier being formed by a strip of compressed absorption material extending continuously from one longitudinal edge of the diaper to the other.
Claim 3
Dependent Claim
71 words
A diaper for insertion in baby pants, comprising outer layers, and an intermediate layer, the latter layer being sandwiched between the outer layers and forming a thick fore portion of absorption material and a thin rear portion of absorption material, a barrier preventing flow of liquid from said front portion to said rear portion being formed by a hydrophobating agent inserted in the border region between said front and rear portions.
Claim 4
Dependent Claim
71 words
A diaper for insertion in baby pants, comprising outer layers, and an intermediate layer, the latter layer being sandwiched between the outer layers and forming a thick fore portion of absorption material and a thin rear portion of absorption material, a barrier preventing flow of liquid from said front portion to said rear portion being formed by a hydrophobating agent inserted in the border region between said front and rear portions.
Claim 5
Dependent Claim
79 words
A diaper for insertion in baby pants, comprising outer layers, and an intermediate layer, the latter layer being sandwiched between the other layers and forminG a thick fore portion of absorption material and a thin rear portion of absorption material, a barrier preventing flow of liquid from said front portion to said rear portion being formed by an agent capable of increasing the viscosity of the absorbed liquid inserted in the border region between said front and rear portions.
