Abstract
Abstract A protector against incontinence comprises an oblong absorbent body which is fixed to a bottom liquid-tight layer extending outside the absorbent body. The lateral edge portions of the layer are folded in over the absorbent body and form side flaps, the distance between the edges thereof being less than the width of the absorbent body at its mid section. The side flaps are fixed at their ends to the bottom layer. An elastic line, arranged at the edge of each side flap, tends to contract itself and thereby the edges of the side flaps. When the protector is put on, the edges of the side flaps come into elastic sealing contact in the thigh creases of the crotch.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
Protector against incontinence or diaper which when extended has an essentially rectangular shape and which comprises a bottom, liquid-tight layer such as a plastic sheet, which carries an oblong absorbent body fixed to the bottom layer, the bottom layer being provided with longitudinal elastic lines such as elastic threads, bands or lines of elastic coating arranged along at least a portion of the length of the protector to gather together the protector in the free state by elastic contraction of the elastic portions and to effect elastic and sealing contact with adjacent bodily parts in the position for use, characterized in that the bottom layer is extended to the sides with side flaps which are folded in over the bottom layer, that said side flaps are fastened at their end portions to the bottom layer, and that the elastic lines are arranged at the free edges of the side flaps.
Claim 2
Dependent Claim
150 words
Protector against incontinence or diaper which when extended has an essentially rectangular shape and which comprises a bottom, liquid-tight layer such as a plastic sheet, which carries an oblong absorbent body fixed to the bottom layer, the bottom layer being provided with longitudinal elastic lines such as elastic threads, bands or lines of elastic coating arranged along at least a portion of the length of the protector to gather together the protector in the free state by elastic contraction of the elastic portions and to effect elastic and sealing contact with adjacent bodily parts in the position for use, characterized in that the bottom layer is extended to the sides with side flaps which are folded in over the bottom layer, that said side flaps are fastened at their end portions to the bottom layer, and that the elastic lines are arranged at the free edges of the side flaps.
Claim 3
Dependent Claim
34 words
Protector as claimed in claim 1, characterized in that the width of the absorbent body in its mid section between the ends of the protector is substantially less than the width of the protector.
Claim 4
Dependent Claim
35 words
Protector as claimed in claim 1, characterized in that a top layer, known per se, of liquid-permeable material such as woven or non-woven textile, is fixed onto the top sides of the folded-in side flaps.
Claim 5
Dependent Claim
42 words
Protector as claimed in claim 1, characterized in that the edges of the side flaps are each made with a tunnel in which there is an elastic thread or an elastic band which is fixed at its end portions to the tunnel.
Claim 6
Dependent Claim
42 words
Protector as claimed in claim 1, characterized in that the width of the side flaps lies in the range of one-tenth to one-half of the width of the protector when extended, preferably in the range of one-third to one-fourth of said width.
Claim 7
Dependent Claim
21 words
Protector as claimed in claim 1, characterized in that the absorbent body has essentially the same width along its entire length.
Claim 8
Dependent Claim
23 words
Protector as claimed in claim 1, characterized in that the absorbent body has a narrow mid section and has substantially wider end portions.
Claim 9
Dependent Claim
29 words
Protector as claimed in claim 3, characterized in that the top layer is folded forth and back at its middle portion between the free edges of the side flaps.
Claim 10
Dependent Claim
57 words
Protector as claimed in claim 3, characterized in that the top layer such as non-woven is sealed along two parallel spaced lines to the edge portion of the respective side flap to provide a tunnel in which the respective elastic thread, band or the like is guided and fixed at its ends to the respective side flap.
