ABSTRACT:
An anti-theft dispenser of material wound in a core-free roll is provided. The dispenser includes a substantially planar support and a shaft to support the roll which is perpendicular to the support. The shaft is fitted at its free end with a stop and a compressible anti-extraction element in the shape of a helically extending blade angled relative to the axis of the shaft and having a blade edge and which is axially rotatable on the shaft and is mounted perpendicularly to the support to prevent extraction of the roll in a direction away from the support.
