Abstract
A base-cup for supporting a bottle in an upright position is disclosed for use with a bottle having a semi-hemispherical bottom and having a radial indentation in the lower portion of its otherwise generally cylindrical body. The base-cup includes a sole plate and a cylindrical side wall having an open top edge with an annular bead on the inside thereof, and a bottom edge smoothly merging into the sole plate. The base-cup also includes limit means projecting upward from the sole plate into the interior of the base-cup for preventing the over-insertion of the bottle into the base-cup. Preferred embodiments of the limit means are illustrated which include circumferentially equally spaced and radially extending fillet webs joining the side wall to the sole plate, and upwardly projecting rings situated approximately midway between the center of the sole plate and the point at which the side wall smoothly merges into the sole plate.
