System for producing drinks from a packaging comprising a product to be infused, the system comprising: two half-chambers (22, 42) together forming an infusion chamber inside which the packaging is intended to be infused when it reaches an infusion position; a first and a second part having a relative mobility and partially defining at least one receiving unit (611, 46) intended to receive the packaging before the positioning thereof in an infusion position inside the infusion chamber, wherein, the first part comprises at least one support zone (612, 613) configured to, when the first and second parts are in a first relative position, stop the movement, preferably by gravity of the packaging and enter into contact with the packaging so as to support the packaging in a retaining position preventing the packaging from reaching the infusion position; in the first relative position thereof, the first and second parts thus defining a portion of space intended to receive the packaging in the retaining position; wherein when the first and second parts are in a second relative position, the at least one support zone (612, 613) releases the passage of the packaging making it possible for the latter to reach the infusion position; characterised in that the system comprises a detection member integral with the first part is shaped to: - enter into said portion of space intended to receive the packaging in the retaining position thereof during the relative movement of the first and second parts and before the first and second parts reach the second relative position thereof; - be absent from said portion of space intended to receive the packaging in the retaining position thereof when the first and second parts are in the first relative position thereof. two half-chambers (22, 42) together forming an infusion chamber inside which the packaging is intended to be infused when it reaches an infusion position; a first and a second part having a relative mobility and partially defining at least one receiving unit (611, 46) intended to receive the packaging before the positioning thereof in an infusion position inside the infusion chamber, wherein, the first part comprises at least one support zone (612, 613) configured to, when the first and second parts are in a first relative position, stop the movement, preferably by gravity of the packaging and enter into contact with the packaging so as to support the packaging in a retaining position preventing the packaging from reaching the infusion position; in the first relative position thereof, the first and second parts thus defining a portion of space intended to receive the packaging in the retaining position; wherein when the first and second parts are in a second relative position, the at least one support zone (612, 613) releases the passage of the packaging making it possible for the latter to reach the infusion position; characterised in that the system comprises a detection member integral with the first part is shaped to: - enter into said portion of space intended to receive the packaging in the retaining position thereof during the relative movement of the first and second parts and before the first and second parts reach the second relative position thereof; - be absent from said portion of space intended to receive the packaging in the retaining position thereof when the first and second parts are in the first relative position thereof. - enter into said portion of space intended to receive the packaging in the retaining position thereof during the relative movement of the first and second parts and before the first and second parts reach the second relative position thereof; - be absent from said portion of space intended to receive the packaging in the retaining position thereof when the first and second parts are in the first relative position thereof.
