<p>PCT No. PCT/NO90/00019 Sec. 371 Date Aug. 22, 1991 Sec. 102(e) Date Aug. 22, 1991 PCT Filed Jan. 26, 1990 PCT Pub. No. WO90/08698 PCT Pub. Date Aug. 9, 1990.A compressible body comprising a container and a flexible annular wall member, and the container, in turn, includes a cylindrical side wall and a prestressed locking member. The side wall of the container forms an upper edge and defines a cylindrical space having a given circumference, and the locking member of the container is mounted on the upper edge of the side wall and is inherently biased radially inwardly toward a position inward of that given circumference. The wall member of the bottle is mounted inside the container of the bottle, and that wall member has extended and compressed positions. In the extended position, the wall member extends upward from the container; and in the compressed position, the wall member is at least substantially contained within the container and the upper portion of the wall member is below the locking member of the container. Moreover, when the wall member is compressed into its compressed position, the locking member moves radially inwardly, due to is inherent resiliency, to a locking position in which the locking member extends directly over the upper portion of the wall member and locks that wall member inside the container.</p> |
