Abstract
Abstract A POOL COVER FOR KEEPING SOOT AND OTHER PARTICLES OUT OF A POOL AND FOR PREVENTING UNWANTED USAGE OF THE POOL. The pool cover is made of a flexible, durable material and has a central cover portion adapted to rest on the surface of the pool. A border region is secured to the outer edge of the central cover portion including a plurality of separate and independent liquid containers capable of being filled with a suitable liquid, such as water. The border region of the pool cover rests on the peripheral edge of the pool and is too heavy to be removed by a child of tender years. If one of the liquid containers inadvertently ruptures, the others will not be affected and the pool cover will be maintained in place.
