The present invention relates to a removable device for preserving and releasing a product contained in a reservoir (2) having a rupturable wall. Said device is in the form of a stopper (1) intended to be fitted on a container (5) and comprises: - a cap (3) which is able to engage with the neck (50) of the container (5) and through which passes a hollow dispensing tube (12) which leads into said container (5); - and an insert (4) able to be positioned on or in the neck (50) of the container. The cap (3) and the insert (4) delimit a rigid chamber (10) of variable volume, containing at least one reservoir (2) containing said product and at least one opening (11) for releasing the product in the container (5). Means enable the cap (3) and the insert (4) to be moved closer together, reducing the volume of the chamber (10) and rupturing the reservoirs (2). These means consist of a screw thread (30) present on the cap (3) and engaging with the screw thread (51) on the neck (50).

La présente invention concerne un dispositif amovible pour la conservation et la libération d'un produit contenu dans un réservoir (2) comprenant une paroi rupturable. Ledit dispositif se présente sous la forme d'un bouchon (1) destiné à être monté sur un récipient (5), et comprend : - un capuchon (3) apte à coopérer avec le goulot (50) du récipient (5) et traversé par une cheminée (12) de distribution débouchant dans ledit récipient (5) - un insert (4) apte à être positionné sur ou dans le goulot (50) du récipient. Le capuchon (3) et l'insert (4) délimitent une chambre (10) rigide à volume variable contenant au moins un réservoir (2) contenant ledit produit, et au moins une ouverture (11) pour la libération du produit dans le récipient (5). Des moyens permettent le rapprochement du capuchon (3) de l'insert (4), entraînant une diminution du volume de chambre (10) et la rupture des réservoirs (2). Ces moyens consistent en un pas de vis (30) présent au niveau du capuchon (3) et coopérant avec le pas de vis (51) du goulot (50).
