Abstract: An apparatus for breaking off the head of a glass ampoule that is composed of a cylindrical body, a neck forming a predetermined breaking point and a head, comprising an incline extending in an inclined manner to the axis of the ampoule to be inserted toward the same, a first support surface is disposed on the side of the incline causing a break-off of the head in the region above the bottom of the ampoule to be inserted at a radius of the ampoule from the axis of the apparatus and a second support surface is disposed on the opposite side beneath the neck of the ampoule at a distance from the axis of the apparatus that corresponds to the radius of the ampoule, during a relative movement of the apparatus to the ampoule in the direction of the axis thereof the incline breaks off the head at the neck.

Abstract: An apparatus for breaking off the head of a glass ampoule that is composed of a cylindrical body, a neck forming a predetermined breaking point and a head, comprising an incline A extending in an inclined manner to the axis of the ampoule to be inserted toward the same, wherein a first support surface (C) is disposed on the side of the incline (A) causing a break-off of the head in the region above the bottom of the ampoule to be inserted at a radius of the ampoule from the axis of the apparatus and a second support surface (B) is disposed on the opposite side beneath the neck of the ampoule (inserted in the apparatus) at a distance from the axis of the apparatus that corresponds to the radius of the ampoule, wherein during a relative movement of the apparatus to the ampoule in the direction of the axis thereof the incline (A) breaks off the head at the neck.
