The hybrid plug is a single component replacement for three components, the paint plug, conventional plug and capseal in a drum closure. It is formed from a single sheet of metal and has a plug portion and a capseal portion which vary in thickness. The plug portion has a collar and an externally threaded wall with a plug gasket disposed on a plug gasket seat. The capseal portion is provided with ears and scoring to enable separation from the plug portion and with a lining on the inner wall of the capseal portion to safeguard against plug gasket failure. The capseal portion may be recessed at intervals to form dimples which hold the hybrid plug in place in an automated insertion process. The hybrid plug provides a passage for air and gases during paint curing and leak testing without necessitating removal.

A two-piece dispensing closure for dispensing essential oils includes an insert received into a container opening and a closure body including a dispensing spout and a hinged cap. The cap is connected to the closure body by a living hinge to allow the user to selectively open and close the container. A tamper-evident tear strip is integrally formed with the closure body. The insert and the closure body including mating helical ramps which cooperate to insure that the insert remains installed within the container neck when the closure body is removed after purchase.

A cartridge (1) which is suitable to cooperate with the neck (3) of a container (5) in order to allow a product contained in the cartridge (1) to flow out into said container (5), said cartridge (1) including at least one reservoir (7); moveable sealing means (13) to close the opening (9) of the reservoir (7), and a socket (23) wherein the moveable sealing means (13) comprises at least one ring (19, 21) configured to cooperate with the neck (3) of the container (5) in order to allow the moveable sealing means (13) to slide along the lower wall (11) of the reservoir (7) by a pressure exerted on said ring (19, 21) by the neck (3) of the container (5) causing the opening of the one or more flaps (17) and further wherein at least one ring (19, 21) of the moveable sealing means (13) comprises holding lugs (25) configured to cooperate with an internal relief (27) of the socket (23) in order to maintain the moveable sealing means (13) in position inside the socket (23), closing the opening (9) of the reservoir (7).

A safety capsule for a container, comprising: a threaded closure cap (2) for closing the container; a cover (3) for said cap (2), said cover (3) comprising a base (30) and a lateral wall (31) that extends from said base (30); said base (30) and said lateral wall (31) overlying said cap (2); a press-fit engagement means (5) that enables transmission of motion from the cover (3) to the cap (2) for unscrewing said cap (2); means (6) preventing extraction of the cover (3) from the cap (2), said means (6) comprising:
a) a strip (60), being part of the cover (3), bent towards the inside of the cover (3);
b) a stopping abutment (61), being part of the cap (2), intended to abut said strip (60) at least whenever there is an attempt to pull out the cap (2) from the cover (3).

A 2-piece closure includes a cap having a first skirt perpendicular to, and extending downwardly from, a first circular top wall. The first skirt includes a groove and a first anti-rotation formation. A tamper band attaches to the first skirt by frangible members. A cap cover includes a second skirt extending downwardly from a second circular top wall. The second circular top wall and the second skirt define an interior having a groove engagement formation and a second anti-rotation formation. The cap cover encloses a portion of the cap, with the groove engagement formation and the groove engaged. The first and second anti-rotation formations interact to restrict rotation of the cap cover relative to the cap.

A container closure of synthetic resin is used for a container having a mouth-and-neck portion formed with an external thread on its outer periphery and an engaging jaw portion positioned below the external thread. The closure including a body and a tamper evident skirt portion is not entirely separated from the mouth-and-neck portion of the container even after unsealing the container at the mouth-and-neck portion. The container closure is improved such that the body is held sufficiently reliably at a required opening position when the body detached from the mouth-and-neck portion is pivoted to the opening position even if the container closure has a relatively short axial length. Furthermore, when the body is pivoted again to the opening position, a sound recognizable for a consumer is generated with sufficient certainty. At least in an angle region in which a protruding piece formed on the skirt wall of the body is present, an extending portion is formed at an engaging piece formed on the tamper evident skirt portion. In a state where the container closure of synthetic resin is mounted on the mouth-and-neck portion, the extending portion is positioned between the engaging jaw portion of the mouth-and-neck portion and the tamper evident skirt portion.

A container closure and methods are disclosed for providing visible evidence of removal of the closure from a container after installation by a manufacturer. The closure includes tamper evidence bridges comprising small tabs of material that extend from a bottom-most edge of the closure to a tamper evidence ledge of the container. The bridges break when the closure is rotated relative to the tamper evidence ledge, thereby providing readily visible evidence that the closure has been removed after installation by the manufacturer. In some embodiments, a tamper evidence closure engages with threads of a finish of the container. Cam locks around the perimeter of the tamper evidence closure are permanently flared by cams on the finish during loosening of the closure. Outward flaring of the cam locks provides a visual indication that the tamper evidence closure has been loosened after installation by a manufacturer.

A closure for a container includes a cap connected to a retaining ring. The cap includes a cover and a skirt. A plurality of concentric threads are disposed on an inside surface of the skirt. The plurality of threads includes at least a first thread at a first level and a second thread at a second level. The first thread is comprised of at least a first thread segment separated from a second thread segment by a first space. The second thread is comprised of at least a third thread segment separated from a fourth thread segment by a second space. A plurality of latch segments includes a first latch segment separated from a second latch segment by a third space. The first space, the second space, and the third space at least partially overlap in along a radial direction of the cap to provide a flex point.
