ABSTRACT:
A device for loosening and tightening threaded caps on the neck of bottles and bottle-like containers, the device having a body with a conically widening inner cavity dimensioned to accommodate the customary bottle cap sizes. On the inner surface of the cavity there is a thread with a pitch the direction of which is opposite to the direction of the pitch of the thread of the bottle-cap. By the aid of the thread the device is pressed onto the cap and loosens it on the bottle neck when the device is screwed onto the cap in its opening direction. In the body there is at least one longitudinal opening running parallel to the longitudinal axis of the conical cavity and a blocking element is arranged movably in said opening, however fixed against falling out, and the outer surface of the blocking element is an actuating part while the surface facing the inside of the cavity is toothed and the teeth penetrate between the threads in the cavity and slide freely along the surface of the cap in the opening direction while in the closing direction, when pressed to the cap, the edges of the teeth engage the surface of the cap and tighten it on the bottle neck.
