Systems, methods, and apparatuses for sealing bottles with a Roll-on Pilfer Proof (ROPP) closure and a childproof overcap are provided. More specifically, the present disclosure relates to an overcap that can be placed onto or formed onto the ROPP closure. The overcap has a retainer that secures the overcap to the ROPP closure and allows the overcap to move relative to the ROPP closure in a longitudinal axis. The overcap moves between a first position or mode of operation where the overcap can rotate about the ROPP closure and a second position or mode of operation where the overcap engages the ROPP closure to transmit a twisting or torque force to the ROPP closure and open the bottle.

A metal cap in which a linear to be held to a cap body and separable from the cap body can be formed by a series of operations for forming the cap body and press molding the liner. The liner of the metal cap has a double-layer structure including a barrier layer on a top panel wall side and a sealing layer on the inner side of the cap body, and the barrier layer is temporarily bonded to the top panel wall with a weak adhesive at the time of molding the barrier layer and separated from the top panel wall by the natural cooling of the barrier layer after molding.

An elongate wine bottle with an internal space for holding wine therein includes a hollow and cylindrical body with a closed bottom and a cylindrical neck extending to an open outer end of the wine bottle remote from the bottom. A thickness of a material from which the wine bottle is manufactured is the same over at least substantially the whole length of the wine bottle. The neck is provided along its outer surface with an external screw thread and only a single annular edge situated below the screw thread relative to the open outer end. A diameter of the circular cross-section of the body is at least substantially equal to a diameter of the circular cross-section of the neck such that the wine bottle has at least substantially one and the same bottle diameter along its whole length.

Disclosed is a metallic cover cap for sealing a metallic bottle, comprising a gasket provided with a flat central zone and an annular zone which includes an outer rim and an inner rim that are separated by a notch, such that the outer rim extends axially, continues circumferentially, and includes: a first surface; a second surface with a flat portion and a concave portion radially opposite the notch; and a third flat surface that extends between the first and second surfaces, and the inner rim extends axially, continues circumferentially and spaced radially inwards of the first rim, and includes: a first flat surface opposite and perpendicular to the flat zone; a second concave surface radially opposite the notch; and a third flat surface between the first and second surfaces that is inclined toward the notch.

Disclosed is a metal container including a neck, wherein a screw thread and a ring collar are provided. The screw thread: includes a top radius between 0.85 and 1.2 mm and a bottom radius between 0.5 and 0.7 mm; the lower flank of the ring collar, which diverges from the top flank in the direction of the longitudinal axis, defines an angle of between 20 and 30 relative to a plane perpendicular to the longitudinal axis; the outer rim of the bottom flank of the ring collar has a radius between 0.7 and 0.9 mm, andthe inner rim of the lower flank of the ring collar is provided at a distance of between 13 and 15 mm relative to the free rim of the neck.

A bottle-shaped can in which a cap can be mounted on a neck portion without damaging slits and bridges. An annular bead comprises a diametrically largest portion, an upper inclined surface, and a lower inclined surface. An angle of inclination of the upper inclined surface is narrower than that of the lower inclined surface. A thread ridge comprises an incomplete thread portion in which a groove depth is shallower than an average groove depth of the thread ridge, and the incomplete thread portion is formed at one end of the thread ridge on the upper inclined surface at least partially. An angle of inclination of a lower wall of the thread ridge w is greater than that of the upper inclined surface so that a protruding corner is formed. The slits and the bridges are situated at a level lower than the protruding corner.

A closure (10) is provided. The closure (10) comprises a body portion (20) having engagement means (45) for engagement with a container(15), and a shell for engagement with the body portion (20), wherein the shell comprises securing means (80) arranged in use to secure the engagement means (45) onto the container(15). The container (15) may be a bottle. The body portion (20) may be a pourer fitment. The engagement means (45) may comprise at least one clip. The securing means (80) may comprise a bead.

An assembly includes a container with a neck and a tamper-evident closure coupled to the container. The neck has a projection with a groove and a ramp. The tamper-evident closure includes a skirt with two portions engaged with the groove and the ramp. The skirt may be rotated relative to the neck to enlarge a diameter of the skirt and disengage the skirt from the neck.

A method for securing a tamper evident closure to a container includes providing a pre-threaded closure that is defined by a top portion and a skirt portion that extends from the top portion. The skirt portion defines an inner closure thread surface and an opposed outer closure thread surface of at least one closure thread. The skirt portion also includes a tamper evident band. The pre-threaded closure is rotated to engage the at least one closure thread with at least one container thread of a container. The inner closure thread surface contacts a surface of the at least one container thread. The tamper evident band of the pre-threaded closure is rolled to secure the tamper evident band to the container.

A seal and method of forming a seal for a resealable container includes a removable cap that is selectively received over a pour opening formed in a can body. A seal is adhered to the end wall of the cap and includes a continuous, first axial region extending outwardly from the inner surface of the cap. The seal first region is dimensioned for engagement with the opening in the container and sealing the container along an inner diameter thereof. Reduced on-torque/off-torque are required since the seal is formed on the inner diameter, and a down force is substantially reduced to assemble the cap to the container.
