Claim 16

The pad of claim 13, in which the bonding material is thermally sensitive and is contained in said cover material and is locally released into the margin of said wadding by local marginal compression of said layers in the presence of heat.

Claim 17

A disposable pad of generally circular planform which is locally radially cut to permit conical formation upon overlap of the cut edges, a flexible plastic sheet having on one side a tacky adhesive for self-sticking to a garment, a protective sheath partably carried by said adhesive, and a layer of high-absorbency material adhered to and substantially covering the other side of said sheet, said sheet and layer being continuously bonded essentially only along the circular and radial margins of said pad.

Claim 18

A disposable pad of generally circular planform which is locally radially cut to permit conical formation upon overlap of the cut edges, a flexible plastic sheet having on one side a tacky adhesive for self-sticking to a garment, a protective sheath partably carried by said adhesive, and a layer of high-absorbency material adhered to and substantially covering the other side of said sheet, said sheet and layer being continuously bonded essentially only along the circular and radial margins of said pad.

Claim 19

The pad of claim 15, in which a relatively thin top porous flexible layer covers said high-absorbency material and is adhered to aid high-absorbency material along said circular and radial margins.

Claim 20

The pad of claim 15, in which the margin includes a continuous edge of most-reduced thickness, and an adjacent continuous strip of less-reduced thickness which is at least no greater than substantialLy one half the thickness of the main body of the pad.

Claim 21

A flat disposable body-contact pad of generally circular planform and having a local generally radially extending cut portion, said pad being adapted to be removably carried by self-adhesion to an inner concave surface of a garment, comprising (a) a layer of high-absorbency fill material, (b) a relatively thin top cover layer of flexible porous material, said top layer and said fill layer being continuously secured to each other about the periphery of said pad, (c) an impervious thin pliable back layer adhered to the underside of said fill layer, (d) a non-toxic contact-type adhesive surface on the exposed surface of said pliable back layer, the adhesive providing sufficient tack to retain the mounted pad to the inner fabric surface of a garment, said adhesive being disposed to remain on the pliable cover as the used pad is peeled from the garment, and (e) a pull-away cover sized to cover the non-toxic adhesive surface of the back layer, the pull-away cover being disposed for ready release from the adhesive; said adhesive surface being characterized by a relatively narrow and straight course extending substantially diametrically across said planform and aligned generally along one edge of the radially cut portion, whereby upon removal of the pull-away cover, the adhesive along the cut edge serves to retain a formed generally conical shape and the remaining adhesive serves to detachably retain assembly to a garment.

Claim 22

A flat disposable body-contact pad of generally circular planform and having a local generally radially extending cut portion, said pad being adapted to be removably carried by self-adhesion to an inner concave surface of a garment, comprising (a) a layer of high-absorbency fill material, (b) a relatively thin top cover layer of flexible porous material, said top layer and said fill layer being continuously secured to each other about the periphery of said pad, (c) an impervious thin pliable back layer adhered to the underside of said fill layer, (d) a non-toxic contact-type adhesive surface on the exposed surface of said pliable back layer, the adhesive providing sufficient tack to retain the mounted pad to the inner fabric surface of a garment, said adhesive being disposed to remain on the pliable cover as the used pad is peeled from the garment, and (e) a pull-away cover sized to cover the non-toxic adhesive surface of the back layer, the pull-away cover being disposed for ready release from the adhesive; said adhesive surface being characterized by a relatively narrow and straight course extending substantially diametrically across said planform and aligned generally along one edge of the radially cut portion, whereby upon removal of the pull-away cover, the adhesive along the cut edge serves to retain a formed generally conical shape and the remaining adhesive serves to detachably retain assembly to a garment.
