发明名称 Mechanical lottery
摘要 It consists of a hollow, transparent prismatic-rectangular body open at one of its bases at which a cover is positioned, having a plurality of internal partitions forming compartments in which respective dice are housed, which cover can in no way be uncoupled from the mouth of the body without destroying the game, so that the dice cannot be manipulated directly by hand, but only by shaking the cover-body assembly. Nevertheless, the cover is displaceable towards the bottom of the body to a full locking position for the dice, in order to maintain a determined combination thereof, subject to a prize, stable, this locking position being secured with the help of means which locks the cover in opposition to springs which tend to house it in the body mouth.
