The present invention mainly improves an absorbent pad that absorbs the fluid discharged from the body of a person (mostly female) such as menstrual or urinary incontinence. The present invention relates to a leak-proof disposable absorbent pad so as to be prevented (blocked).

In more detail, the liquid permeable surface sheet and the liquid impermeable back sheet are stacked up and down, and the edges are adhered or glued (glue: hot melt), and the superabsorbent polymer is formed between the liquid permeable surface sheet and the liquid impermeable back sheet. In the absorbent pad incorporating the (core), a split type leakage barrier sheet is provided (fused and glued) or formed on both sides in the longitudinal direction (front and rear) of the upper surface of the absorbent pad so as to form an opening toward the center. By installing (welding and adhering) the integrated leakage blocking sheet with the inlet hole on the upper surface, the fluid discharged into the super absorbent polymer (core) from the absorbent pad is leaked through the liquid permeable surface sheet. Even if it occurs, the leak-blocking sheet adhered to the outer surface (top) blocks it, preventing fluid discharge from contacting the skin. Block leaking to type intended to provide a disposable absorbent pad.

As is commonly known, disposable absorbent pads are worn tightly using panties or diaper covers and the like, and are adapted to absorb and receive fluid discharges (physiological blood or urine, etc.) discharged from the wearer's body by menstrual or incontinence. .

Disposable absorbent pads are basically a liquid-permeable surface sheet (permeable body contact layer or overlap) that is in contact with the body and is permeable, and is supported by (attached) by panties or diaper covers, etc. Absorption layer (absorption) located between the sheet (impermeable protective barrier layer) and the liquid-permeable surface sheet (permeable body contact layer or overlap) and the liquid-permeable backsheet (impermeable protective barrier layer) Core) as a basic element.
