| 摘要 |
Partial cutting-out of a truncated ovoid 2, inside a rectangular sheet 1, which is folded down perpendicularly inside the rear of the pan, suspended from the seat by a transverse strip forming a hinge 3 and has an axial slit 4 extended by preliminary cutting-out at the two ends 5. The user operates the flush. The water under pressure is projected under the male ovoid 2, flows through the slit 4, widens it in the shape of a truncated cone and propels it forward towards the bottom of the pan. The protection is carried away. The absorbed assembly, disintegrated by the action of the preliminary cutting-out 5 is flushed away in the pan. The truncation of the base of the ovoid prevents it from hanging into the water remaining in the bowl. Product designed for all public WCs. Packaging in hand-bag packets, WC dispensers. <IMAGE>
