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).
Claims27
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 defining 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 connecting the engagement portion with the retention configurations to provide engagement between the cap and the glass receptacle producing a compression force on the closing portion 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, the sealing ring being retained within the cap when the cap is in a detached position from the glass receptacle by having an outer diameter bigger than the local narrowing;
- 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.
(canceled)
The container according to claim [1] wherein the closing portion is made of a metal sheet or is made of a metal sheet and includes a bumped central area collapsible under a vacuum existent in the interior of the container as a tamper evidence.
The container according to claim [1] wherein the closing portion has an outer diameter equal or smaller than the local narrowing of the inner diameter of the cylindrical segment.
(canceled)
The container according to claim [1] wherein the retention configurations of the cylindrical neck are defined by a thread surrounding said cylindrical neck and wherein the releasable closure mechanism is defined by engagement configurations defined by local deformations or folds of the metal sheet constitutive of the cylindrical segment, the engagement configurations being complementary to the thread.
(canceled)
The container according to claim [1] wherein said one or more radial protrusions is one continuous protrusion surrounding the cylindrical segment of the engagement portion.
The container according to claim [1] wherein the one or multiple radial protrusions of the cylindrical segment are one or multiple tapered surfaces determining an inner diameter of the cap cylindrical segment that increases as the distance from the closing portion decreases, retaining the sealing ring therein.
The container according to claim [1] wherein the closing portion includes an inner annular protrusion or and inner annular protrusion and an outer annular protrusion, the inner annular protrusion is concentric with the cylindrical segment and protrudes towards the receptacle opening, and the outer annular protrusion is concentric with the cylindrical segment, surrounds the inner annular protrusion and protrudes towards the receptacle opening, the sealing ring being compressed between the annular mouth and the inner annular protrusion or between the annular mouth and the inner and outer annular protrusions and being retained in a centered position between said inner annular protrusion and the inner diameter of the cylindrical segment.
(canceled)
(canceled)
The container according to claim [1] wherein the portions of the cap made of a metal sheet are made of unpainted and unvarnished sheet of stainless steel.
The container according to claim [1] wherein the cylindrical segment includes a slit passage between the closing portion and the radial protrusions, facing a side edge of the sealing ring.
