Abstract
A container with a reusable cap, including a glass receptacle (10) with a receptacle opening (11) surrounded by an annular mouth (12) and by a cylindrical neck (13) including a retention configuration; a cap (20) including a closing portion (30) completely covering the receptacle opening (11) and an engagement portion (40) made of a metal sheet; a releasable closure mechanism connecting the engagement portion (40) with the retention configurations and a sealing ring (50), the engagement portion including radial protrusions (41), directed inwards and determining a local narrowing, the sealing ring (50) being not adhered to the cap and being retained within the cap (20).
Claims20
A container with a reusable cap, including:
- a glass receptacle provided with a receptacle opening surrounded by a cylindrical neck including retention configurations on a cylindrical outer surface thereof, said cylindrical neck including an annular mouth surrounding the receptacle opening;
- a cap including a closing portion completely covering the receptacle opening and an engagement portion made of metal sheet and including a cylindrical segment with an inner diameter;
- a releasable closure mechanism integrated in or connected to the engagement portion of the cap and configured to connect the engagement portion with the retention configurations of the glass receptacle to provide engagement between the cap and the glass receptacle producing a compression force on the closing portion of the cap towards the annular mouth when the cap is in an attached position;
- and
- a sealing ring with an outer diameter equal to or smaller than the inner diameter of the cylindrical segment and compressed between the annular mouth and the closure portion providing a tight seal;
- the cylindrical segment includes one or multiple radial protrusions, directed inwards, defined by local deformations of the metal sheet and placed at a distance from the closing portion, said radial protrusions determining a local narrowing of the inner diameter of the cylindrical segment to a diameter smaller than an outer diameter of the sealing ring, the radial protrusions being separated from the closing portion a gap distance in an axial direction, said gap distance containing the entire thickness of the sealing ring interposed between the radial protrusions and the closing portion, the radial protrusions being in contact with the sealing ring in the axial direction when the cap is in a detached position from the glass receptacle, thereby retaining the sealing ring between the radial protrusions and the closing portion;
- the sealing ring is not adhered to the cap;
- the engagement portion, or a portion of the engagement portion excluding the cylindrical segment, is independent from the closing portion and further comprises a ring mouth segment overlapped to a perimeter area of the closing portion, retaining said closing portion between the ring mouth segment and the sealing ring.
