Device for exchanging a bottle closure

A device for extracting a bottle stopper of a bottle having fluid contained therein, comprising:

• an airtight container detachably mountable on a head of the bottle via a mounting mouth;
• a corkscrew contained in said airtight container together with a substitute stopper;
• and
• an operation body capable of applying a rotational motion to said corkscrew with one hand of a user from outside of the airtight container while holding the bottle with the other hand of the user, said rotational motion being used to detach the bottle stopper from the head of the bottle,
• wherein at least a part of said airtight container is made of a deformable member, the deformable member comprising a deformable bag attached to the mounting mouth, and wherein the substitute stopper is able to be mounted on the head of the bottle in place of the bottle stopper detached;
• and wherein applying said rotational motion and manipulating said substitute stopper are carried out from an outside of said airtight container by employing a flexibility of the deformable member.

• an airtight container detachably mountable on a head of the bottle via a mounting mouth;
• and
• a bottle opening member contained in said airtight container together with a substitute stopper;
• wherein at least a part of said airtight container is made of a deformable member, the deformable member comprising a deformable bag attached to the mounting mouth;
• and
• wherein the deformable member is flexible to allow a user from an outside of said airtight container i) to operate said bottle opening member:
• ii) to engage the bottle opening member with the bottle stopper, iii) to remove the bottle stopper from engagement with the bottle;
• and iv) to mount the substitute stopper on the head of the bottle;
• while maintaining the airtight seal between the airtight container and the bottle.
