Abstract:
1. An improved portable drink dispensing device for collective use comprising: a drink receptacle having a plurality of liquid emptying orifices formed in an inner bottom surface thereof that are each obturated with a valve; a support base to demountably secure the drink receptacle; a plurality of pouring mechanisms that serve to open the valves of the drink receptacle; and a removable cooling element capable of cooling fluid within the drink receptacle, wherein the inner bottom surface of the drink receptacle includes a convex central portion surrounded by a flat outer portion, wherein the liquid emptying orifices are positioned in the flat outer portion and angularly equidistant from one another, an outer bottom surface of the drink receptacle having a concave central area and a perimeter area that includes a plurality of cylindrical housings that are aligned with the liquid emptying orifices and configured to engage the valves; the support base includes an upper portion shaped to receive a lower portion of the drink receptacle, the lower portion of the drink receptacle including a perimeter flange and a support edge that are received within the upper portion of the support base, the support base additionally has a plurality of support legs that extend from the upper portion; the plurality of pouring mechanisms are mounted angularly equidistant on the support base, each one of the plurality of pouring mechanisms having a pouring lever that can move upward and downward relative to the upper portion of the support base and a nozzle for liquid exit mounted in a housing on an inner surface of the upper portion of the support base, the nozzle being mechanically coupled to the pouring lever so that downward movement of the pouring lever results in upward movement of the nozzle into a valve opening to release liquid from the drink receptacle; each of the plurality of pouring mechanisms is provided with a lever support wherein a spin axis for the pouring lever is mounted, a helicoidal spring and a sliding part are mounted through an opening provided in the upper portion of the support base and a pair of guides extends along opposed sides of each opening to allow for the sliding part and the lever support to be operationally coupled to the nozzle, so that downward movement of the pouring lever relative to the support base causes the lever support to pivot around the spin axis and move the sliding part upward which drags the nozzle upward to press against the respective valve opening and the helicoidal spring serves to return the nozzle, the sliding part, and the pouring lever to an initial position; the cooling element is demountably fixed within the upper portion of the support base and has a generally cylindrical shape with a convex upper surface that rests against the concave central area of the outer bottom surface of the drink receptacle, a flat lower surface that rests on a bottom surface of the upper portion of the support base, and an outer side wall with a plurality of semi-circular recesses formed therein to complement the interior shape of the upper portion of the support base and, in combination with the perimeter flange of the drink receptacle, surround each nozzle of the plurality of pouring mechanisms; the upper portion of the support base includes a blocking-unblocking device which, in a blocked position, prevents the removal of the drink receptacle from the support base and, in an unblocked position, releases the drink receptacle to allow removal from the support base; and wherein the blocking-unblocking device includes a plurality of blocking pieces configured to couple to crenelated projections formed on an inside surface of the perimeter flange of the lower portion of the drink receptacle and an unblocking part configured to be actuated from outside the support base to act on the plurality of blocking pieces.
