Abstract:
A cap having an open position and a closed position for sealing against a scaling surface in an opening of a container, comprising:a.) a handle rotatable between a first position corresponding to the open position of the cap and a second position corresponding to the closed position of the cap;b.) an anchor disk non-rotatably connected to said handle, said anchor disk shaped to pass axially through said opening and to engage an inner edge of said opening to prevent axial passage of the anchor disk through the opening upon rotation of said handle from said first position to said second position;c.) a generally disk shaped sealing member disposed between the handle and the anchor disk and having a seal for engaging said sealing surface upon rotation of said handle from said first position to said second position, said sealing member shaped to non-rotatably sit within said opening to prevent rotation of said seal relative to said sealing surface upon rotation of said handle; andd.) a compression member for biasing the seal into engagement with the sealing surface when said handle is in said second position said compression member movable between a compressed state when said handle is in said first position and an expanded state when said handle is in said second position, said compression member being connected between said sealing member and said handle.
