Blocking device for use with cup receptacles

Blocking means for use with a receptacle for cups pilable in each other and having an external collar, bead or the like, said blocking means being positioned at the discharge opening of the receptacle and including a blocking body having two spaced apart blocking surfaces, one of said surfaces being arranged for holding in a normal position all cups in the receptacle and forming a slide surface for the collar of the outermost cup in said receptacle when said outermost cup is being discharged from said receptacle through said discharge opening, said slide surface being, during the discharge of each of the cups, displaced outwardly laterally of the discharge direction, and the second blocking surface upon the displacement of the slide surface being arranged to be displaced inwardly inside of the collar of the next adjacent cup before this next cup reaches said second blocking surface, said blocking body being provided with spring means, against the action of which the blocking surfaces are displaced and which returns the blocking body to said normal position after a cup being discharged has left the slide surface, said blocking body being mounted for rotation about an axis extending substantially parallel to the discharge direction, and said slide surface from the abutment thereof against the collar in the normal position extending at an acute angle to the discharge direction and successively changing in direction to an orientation which is more and more parallel to the discharge direction.
