Abstract
A device having a base part (1) and a removable member (3) that is mounted in removable manner on the base part (1), the base part (1) and the removable member (3) including a magnetic means (15, 35) that generates axial magnetic attraction between them that is at its maximum in an assembled rest position. The device further includes a mover means (4), distinct from the removable member (3), for moving the removable member (3) axially away from the base part (1), starting from the assembled rest position, by turning an actuator member (7) that forms part of the mover means (4), so as to reduce the magnetic attraction between the base part (1) and the removable member (3), and thus facilitate the removal of the removable member (3).
Claims13
A device comprising a base part (1) and a removable member (3) that is mounted in removable manner on the base part (1), the base part (1) and the removable member (3) including magnetic means (15, 35) for generating axial magnetic attraction between the base part and the removable member that is at a maximum in an assembled rest position;
- the device further comprises mover means (4), distinct from the removable member (3), for moving the removable member (3) axially away from the base part (1), starting from the assembled rest position, by turning an actuator member (7) that forms part of the mover means (4), so as to reduce the magnetic attraction between the base part (1) and the removable member (3), and thus facilitate the removal of the removable member (3);
- and
- wherein the device is configured such that rotation of the actuator member (7) causes removable member (3) to lift axially without rotating and thereby move axially away from the base part.
A fluid dispensing device comprising:
- a reservoir;
- a base part secured to the reservoir and having an opening to an inside of the reservoir;
- a closure mounted in removable manner on the base part, each of the base part and the closure including a respective magnet arranged so that the base part and the closure are held together by an axial magnetic attraction between the respective magnets when closure is mounted on the base part;
- and
- a moving mechanism, distinct from the closure, that moves the closure axially away from the base part, the moving mechanism comprising an axial guide bushing mounted in stationary manner on the base part, an axial thrust cylinder guided axially by the axial guide bushing, an actuator member rotatably mounted on the axial guide bushing (5), a cam between the actuator member and the axial thrust cylinder oriented to urge the axial thrust cylinder in axial movement guided by the axial guide bushing while the actuator member is being turned, such that turning the actuator member reduces the axial magnetic attraction between the base part and closure and thereby facilitates complete separation of the closure from the base part.
