Abstract
Sanitary pads can be made flushable by means of perforation and stress concentrations in the layers to aid ripping before they a flushed into the sewer system, allowing absorbent materials to disperse instead expanding inside the pad and causing sewer blockage.
Claims6
A sanitary pad comprising an impermeable layer, an absorbent layer, a permeable layer, and a sealed region around the absorbent layer, wherein the sealed region is formed by bonding of the impermeable layer and the permeable layer, and where there is a weakening of at least one layer by a cut.
A method comprising causing a sanitary pad to be destroyed after flushing the sanitary pad into a sewer system, wherein causing the sanitary pad to be destroyed comprises disrupting outer layers of the pad, thereby allowing internal absorbent materials within the pad to disperse in the sewer system after flushing.
