<p>An inflatable system comprises an inflatable body (10) having an interior, and exterior, a port (1511) for transfer of air between the interior and exterior and a wall (151) separating the interior and exterior. The inflatable body (10) has a flange (152) attached to the wall proximate to the port and a throat (1521), defined by a deformable rim (1522) around the perimeter thereof, the rim having interior and exterior sides and a top, the throat being disposed within the port, and the flange being configured in the port to require all air being transferred between the interior and exterior of the body to pass through the throat. The inflatable system further includes an assembly for removably covering the throat, the assembly including: (i) a ring-shaped base disposed around the exterior of the rim, (ii) a cap hingedly attached to the base, and (iii) shape means for restricting radially inward movement of the rim at least when the cap is in a closed position, the throat is uncovered, and when the cap is in a close position, the throat is covered by the cap; and in that a valve is disposed in the cap. <IMAGE></p> |
