Device for packaging balls for reaction vessels for an analysis appliance

A device for packaging balls for reaction vessels for an analysis appliance, comprising:

• a body configured to house the balls, an end surface of the body comprising an opening;
• a closing member mounted at the end surface of the body and configured to move pivotably relative to the body about an axis of rotation (B) between a closed position, in which a surface of the closing member closes the opening of the body, and an open position, in which the opening of the body aligns with a surface opening through the surface of the closing member so as to allow the balls to be dispensed from an interior of the body,
• wherein the end surface of the body has a first indentation located on the axis of rotation (B) and configured to permit passage of a coupling member therethrough, and the closing member has a second indentation located adjacent to and coaxial with the first indentation on the axis of rotation (B) and configured to cooperate with the coupling member, the first and second indentations aligned with the axis of rotation (B) so that the coupling member can remain engaged into the first and second indentations when the closing member rotates relative to the body,
• wherein, in the closed position, a shape of the second indentation aligns with a corresponding shape of the first indentation so that, in the closed position, the coupling member passes through both the first indentation and the second indentation so as to be received into a space formed by the second indentation by virtue of a shape cooperation between the coupling member and the second indentation, and
• wherein, in the open position, the second indentation is angularly spaced from the first indentation so that the shape of the first indentation is non-aligned with the shape of the second indentation and the first indentation prevents removal of the coupling member from the space formed by the second indentation through the first indentation.
