Abstract
A box formed by a set of walls closed by a pivoting bottom which is openable so that the object which it carries falls vertically in the ejection zone to be collected in a receptacle. The walls are extended below the bottom so that the pivoting operation may be started before the box quite reaches the ejection zone. The bottom in the closed position forms an angle with the horizontal, thus the object which it carries is automatically jolted against the rear wall during the conveying phase. The portion of the rear wall above the rest position of the bottom is given a slight forward inclination to promote the sliding of the object towards the discharge position. A comb-shaped separation scrapes the bottom (indented) so as to loosen any object adhering abnormally thereto.
