ABSTRACT:
A cover for a pool is retained in position by a plurality of water-filled enclosures, each including a container and a lid formed of a substantially rigid, plastic material having a specific gravity of less than one. The elongated, watertight container has a continuous flange about its upper, open end with openings at spaced intervals to receive locking pins integral with the lid. The lid has a pyramidal-shape to prevent water and debris from collecting thereon. The lid outer perimeter has lip engaging the marginal edge of the container flange to retain its shape without bowing due to the expansion of freezing water. The containers and lids are nestable and stackable when not in use. The container flange openings extend downwardly along an tipper portion of the side walls to prevents overfilling. The lid may be hingedly connected to the container, while retaining the nestable, stackable capability. The sloping top of the lid may be provided with small openings or a screen-like arrangement, to prevent debris from entering into the enclosure. The locking pins are easily released from their associated locking openings to empty, clean and store the enclosure. The plastic material withstands extreme outdoor conditions. Yieldable cone-shaped projections are provided along the container interior to support the lid and allow for ice expansion without bowing or cracking. A releasing agent facilitates movement of the ice. A liquid or plastic vapor barrier is provided to substantially prevent water evaporation.
