Crown caps

The invention "relates to a crown cap made of a flat or slightly curved bottom and a radially running, offset to this bottom closing edge, which has teeth or corrugations.

This crown cap is with a possible sealing washer made of metal and a sealing connection made of cork or some other natural or synthetic material. The sealing washer is applied to the inside of the floor, and the sealing connection is arranged on this sealing washer within the closing edge.

The crown cap according to the invention is intended to be bottles or similar containers close, the neck of which at least one side at the edge

J has ₀ external thread. In general, the external thread of the

φ neck helically around the neck axis.

** · - If the crown cap according to the invention closes a bottle, ^ is its bottom under the interposition of the sealing washer and the sealing connection on the edge of the bottle neck,

rend its closing edge is generally pressed by retraction onto the external thread of the neck, so that the teeth of the

Closing edge with the formation of a thread of the bottle neck corresponding thread are deformed.

The bottle closed by such a crown cap can be opened or uncorked by removing the closing edge from the thread the neck is unscrewed or the closing edge is loosened from the thread,

The bottle opened in this way can be closed again or corked by placing the closing edge on the thread of the neck unscrewed or on the thread thanks to the presence of the thread impressed in the teeth of the closing edge on the neck thread tighten again.

Unscrewing or loosening the closing edge of the crown cork requires the use of a relatively large torque, a lower torque is when re-screwing or tightening of the closing edge on the external thread of the neck is required.

Up to now this torque for screwing and unscrewing was done by hand has been exercised on the crown cap. To do this, grasp the closing edge with your fingers and apply the torque.

The present invention has for the purpose of transmitting the torque to the crown cap by hand using a To facilitate intermediate piece on which this torque is exerted and through which it is transmitted to the crown cap.
