Abstract: In a ball and socket closure for opening and closing an intake port for a hollow fluid container including bicycle mounted bottles such as water or other kind of fluids which refreshes the user or provides nourishment, The ball and socket closure may be used on water bottles or adaptors for sports water bottles used in place of the original bottle cap, Such original bottle caps have no quick fill capability or a selectively open and closed ball and socket intake cap as is in the present invention, which permits introduction of water through the cavity within a spherical ball valve, received by a cylindrical socket for supporting the ball in an intake port of the fluid container. A tab on the edge of the hole in the ball permits manipulation of the ball between an open and a closed position as required by the user.

Abstract: In a quick fill fluid container an adaptor for receiving a hollow container having a cavity or a reservoir for receiving fluids, preferable water but may be any other kind of fluids which refreshes the user or provides nourishment, reasonably necessary to refresh the user. The adaptor has a generally streamlined shape which mounts on to the container, which is typically supported in generally available cages or other mounting devices attached to a bicycle frame or other structure. A hollow extraction tube is provided for the adaptor which extends through the adaptor and into the container for withdrawal of the fluid by the user and preferably includes a mouth piece with a normally closed bite valve which is operated by the user to open the valve to extract water from the container.
