         16 . A cap reservoir device for a food bottle comprising a container with a neck on which the cap reservoir device is intended to be assembled to hermetically close the interior of the container, the cap reservoir device comprising:
 a cap comprising a base part adapted to be fixed to the neck of the bottle,   a capsule disposed in the cap forming a chamber partially closed by a bottom wall, the chamber being filled with a gas hermetically closed by the capsule and the cap, and   a removable actuator comprising a perforator configured to perforate, cut or break the bottom wall, characterized in that the cap reservoir device further comprises:   soluble nuggets comprising an active component surrounded by an envelope or a matrix of a soluble food substance protecting the active component against chemical alteration.   
     
     
         17 . The device according to  claim 16 , characterized in that the soluble envelope or matrix is composed of an amylaceous starch, for example tapioca. 
     
     
         18 . The device according to  claim 16 , characterized in that the active components comprise one or more plant extracts. 
     
     
         19 . The device according to  claim 16 , characterized in that the base part of the cap comprises a crown with an internal thread configured to be screwed onto an external thread of a neck of a bottle. 
     
     
         20 . The device according to  claim 16 , characterized in that the cap comprises a cover part integrally formed with the base part and adapted to sealingly cover the opening formed at the end of the neck of the bottle. 
     
     
         21 . The device according to  claim 16 , characterized in that the part of the cover comprises a removable flexible central part making it possible to push a pusher of the actuator in order to move the perforator to perforate the bottom wall of the capsule. 
     
     
         22 . The device according to  claim 16 , characterized in that the cap comprises a top part forming a leaf relative to the base part, removable from a closed position covering the part of the cover of the cap so not to be able to actuate the pusher of the actuator, at an open or removed position allowing the actuation of the pusher of the actuator. 
     
     
         23 . The device according to  claim 16 , characterized in that the bottom wall is a thin polymeric film such as a flexible PET film. 
     
     
         24 . The device according to  claim 16 , characterized in that the capsule comprises a fixing part in the form of a flange fixed to the base part of the cap. 
     
     
         25 . The device according to  claim 16 , characterized in that the capsule comprises a side wall sealingly connected to the bottom wall before actuation, the side wall being fixed to the base part of the cap and intended to be inserted inside the neck of the container. 
     
     
         26 . The device according to  claim 16 , characterized in that the actuator comprises a pusher comprising a rod extending in a cover part of the cap and the perforator disposed adjacent to the bottom wall. 
     
     
         27 . The device according to  claim 26 , characterized in that the rod comprises a hook engaging a fixing part of the capsule to retain the actuator in a lower position ensuring the opening of the bottom wall after actuation. 
     
     
         28 . The device according to  claim 16 , characterized in that the device comprises a plurality of soluble nuggets, at least one nugget having active components different from at least one other nugget. 
     
     
         29 . The device according to  claim 16 , characterized in that the cap, the capsule and the actuator are composed of one or more molded polymers, such as injected PET, the cap being disposable. 
     
     
         30 . A food bottle comprising a container and a neck forming the opening of the container, the neck comprising an external thread and an internal surface, and a cap reservoir device according to  claim 16 , screwed onto the neck hermetically closing the interior of the container.
