Receiving device for receiving a bottle on a carbonation machine; carbonation machine, and method for using a carbonation machine

A carbonation machine comprising:

• a receiving device for receiving a bottle, the receiving device has a fastening device for fastening the bottle, the fastening device comprises an iris device, the iris device has an opening, the opening of the iris device is configured to have a variable size,
• wherein the receiving device is transferable from a bottle-receiving state, which is configured for receiving the bottle, into an attachment state, in which the bottle is attached to the receiving device,
• wherein as the receiving device is transferred from the bottle-receiving state into the attachment state, a size of the opening of the iris device decreases,
• wherein in the bottle-receiving state, the bottle is arranged in a non-vertical receiving position on the receiving device;
• and in the attachment state, the bottle is arranged in a preparation position, and as the receiving device is transferred from the bottle-receiving state into the attachment state, the bottle is tilted from the non-vertical receiving position into the preparation position,
• wherein the iris element has a guide means, the fastening device has an intermediate element, the intermediate element has a counterpart guide means which complements the guide means of the iris element,
• wherein as the receiving device is transferred from the bottle-receiving state into the attachment state, the iris element is guided from a radially outer position into a radially inner position by the guide means and the counterpart guide means.

• wherein in the attachment state, the safety element is arranged in front of the bottle such that, by means of the safety element, the bottle is arranged within the carbonation machine,
• wherein the carbonation machine comprises an actuation element for initiation of a carbonating operation by a user, the actuation element being coupled to the safety element such that the carbonating operation can be started only when the safety element has been arranged in front of the bottle such that, by means of the safety element, the bottle is within the carbonation machine.

A method for using a carbonation machine comprising a receiving device for receiving a bottle, the receiving device has a fastening device for fastening the bottle, the fastening device comprises an iris device, the iris device has an opening, the opening is configured to have a variable size, wherein the receiving device is transferable from a bottle-receiving state, which is configured for receiving the bottle, into an attachment state, in which the bottle is attached to the receiving device, wherein as the receiving device is transferred from the bottle-receiving state into the attachment state, a size of the opening of the iris device decreases, wherein in the bottle-receiving state, the bottle is arranged in a non-vertical receiving position on the receiving device;

• and in the attachment state, the bottle is arranged in a preparation position, and as the receiving device is transferred from the bottle-receiving state into the attachment state, the bottle is tilted from the non-vertical receiving position into the preparation position,
• wherein the method comprises:
• a first step, with the receiving device in the bottle-receiving state, the bottle is arranged on the receiving device of the carbonation machine, wherein the bottle has a liquid,
• a second step, the receiving device transferred from the bottle-receiving state into the attachment state, wherein, during the transfer from the bottle-receiving state into the attachment state, the bottle is fastened by the iris device to the receiving device, and
• a third step, the liquid in the bottle is carbonated;
• wherein in or during the second step, as the receiving device is transferred from the bottle-receiving state into the attachment state, an iris element of the iris device is guided by a guide means in a direction of a bottle neck of the bottle such that the bottle is fastened by means of the iris element to the receiving device.
