Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
364 words
An underpad holder for use in combination with a disposable underpad and bedding mattress, said holder comprising, in combination, a plastic base sheet having a length longer than the width of a bed and mattress to which said base sheet is adapted to be applied tightly and with the opposite ends of said plastic base sheet folded around the side edges of the mattress and extending laterally inwardly below said mattress and between said mattress and support means provided on said bed to support said mattress, said plastic base sheet having a width extending lengthwise of said bed and mattress sufficient to cover a portion of the length of said bed likely to be soiled by an occupant of said bed, and a disposable underpad on said plastic base sheet, a single layer, continuous, thin, closed frame having a width extending transverse to the perimeter of said frame, said width defining an outer edge portion larger than said disposable underpad and an inner edge portion smaller than said disposable underpad, said outer edge portion having a pair of opposite outer side edges substantially coextensive with opposite outer side edges of a portion of said plastic base sheet disposed centrally of the lateral dimension of said bed and mattress and also having a pair of outer end edges extending transversely of said opposite outer side edges parallel to the opposite sides of said bed and mattress, means to bond said outer edge portion of said continuous frame to the upper surface of said plastic base sheet while keeping said inner edge portion of said continuous frame free of attachment or bonding to said plastic base sheet and to define a peripherally extending inwardly facing groove free of any interruption between the inner edge portion of said continuous frame and said plastic base sheet adapted to receive the entire perimeter portion of said disposable underpad including all corners of said perimeter portion in flat unwrinkled tucked relation within said peripherally extending groove and to remain in said tucked relation without requiring pinning between said underpad and said holder until such time as a conscious positive force is applied to remove said underpad from said tucked relation.

An underpad holder for use in combination with a disposable underpad and bedding mattress, said holder comprising, in combination, a plastic base sheet having a length longer than the width of a bed and mattress to which said base sheet is adapted to be applied tightly and with the opposite ends of said plastic base sheet folded around the side edges of the mattress and extending laterally inwardly below said mattress and between said mattress and support means provided on said bed to support said mattress, said plastic base sheet having a width extending lengthwise of said bed and mattress sufficient to cover a portion of the length of said bed likely to be soiled by an occupant of said bed, and a disposable underpad on said plastic base sheet, a single layer, continuous, thin, closed frame having a width extending transverse to the perimeter of said frame, said width defining an outer edge portion larger than said disposable underpad and an inner edge portion smaller than said disposable underpad, said outer edge portion having a pair of opposite outer side edges substantially coextensive with opposite outer side edges of a portion of said plastic base sheet disposed centrally of the lateral dimension of said bed and mattress and also having a pair of outer end edges extending transversely of said opposite outer side edges parallel to the opposite sides of said bed and mattress, means to bond said outer edge portion of said continuous frame to the upper surface of said plastic base sheet while keeping said inner edge portion of said continuous frame free of attachment or bonding to said plastic base sheet and to define a peripherally extending inwardly facing groove free of any interruption between the inner edge portion of said continuous frame and said plastic base sheet adapted to receive the entire perimeter portion of said disposable underpad including all corners of said perimeter portion in flat unwrinkled tucked relation within said peripherally extending groove and to remain in said tucked relation without requiring pinning between said underpad and said holder until such time as a conscious positive force is applied to remove said underpad from said tucked relation.
Claim 3
