Abstract
Abstract The invention provides the combination of a dispenser and a series of incontinent or catamenial pads that are connected by easily severably areas. These pads may be rolled without harmful effects to the pad. The rolled pads that are connected by severably means are suitable for combination with a dispensing container that allows them to be withdrawn a single pad at a time. In a particularly preferred embodiment an incontinent pad having elasticized edges and double baffle is connected in series by severably portions at the ends. The pad is placed into a generally cubical box and withdrawn either from the center of the roll at the top of the box or from the end of the roll at the side of the box. The container is provided with a removable section at either the top or side for the withdrawal of pads.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
93 words
A method of forming a combination of a dispensing aid and a series of elasticized pads comprising forming a connected series of absorbent pads having edges that contain a heat-shrinkable elastic material, rolling said pads onto a core, said core having a length of about the width of the absorbent forming a part of said pad, placing said pads in a container and heating said container containing the roll of said pads to shrink said heat-shrinkable elastic material, so that said elasticized pad will assume a bowed condition when dispensed from said container.
Claim 2
Independent Claim
93 words
A method of forming a combination of a dispensing aid and a series of elasticized pads comprising forming a connected series of absorbent pads having edges that contain a heat-shrinkable elastic material, rolling said pads onto a core, said core having a length of about the width of the absorbent forming a part of said pad, placing said pads in a container and heating said container containing the roll of said pads to shrink said heat-shrinkable elastic material, so that said elasticized pad will assume a bowed condition when dispensed from said container.
Claim 3
Dependent Claim
94 words
The method of claim 1 wherein said absorbent pad comprises an impervious backing sheet, an inner generally rectangular absorbent layer and a body-side permeable web wherein said impervious backing extends beyond the long side of said rectangular absorbent layer and is folded back on each side and adhered to said permeable web and absorbent layer, and wherein heat-shrinkable elastic members are adhered within the folds of said impervious sheet and wherein said impervious sheet is adhered to itself in the areas of the folds between said elastic members and the edge of said absorbent.
Claim 4
Dependent Claim
18 words
The method of claim 1 wherein said container is provided with a suitable opening for dispensing of pads.
Claim 5
Dependent Claim
16 words
The method of claim 1 wherein said elastic material shrinks around the end of said core.
Claim 6
Dependent Claim
26 words
The method of claim 1 wherein said heating to shrink is controlled by the user in order to obtain a better fitting pad for the user.
