[Problem] To provide a composite preform that can ensure that worsening of the appearance of a surface of a plastic member caused by near-infrared heating prior to blow molding is effectively prevented and that an inner preform is efficiently heated. [Solution] The composite preform of the present invention includes a preform and a heat-contractive plastic member, the preform including a mouth part; a trunk part linked to the mouth part; and a bottom part linked to the trunk part, and the heat-contractive plastic member being disposed so as to surround the outside of the preform and including at least a colored layer that contains a resin material and a colorant, wherein the heat-contractive plastic member has a near-infrared transmittance of 50% or higher.

The invention refers to a capping device intended to be fixed on a neck (2) of a container including an orifice (3), including the capping device: a cap (1) which has a helical thread (7) intended to cooperate with a helical thread (6) formed in the neck (2); a lower ring (9) fixed axially to the neck (2); a hinge device that connects the cap (1) to the lower ring (9),
including the capping device in addition a cap locking device (1) configured to lock the cap (1) in an open tilted position, including such a locking device a bead (22) which is formed, between the two blades (11, 12), and which is configured to rest against the neck (2) of the container when the cap (1) is in the open tilted position, the heel (22) has an internal face where at least one of the ribs of the helical thread series (7) is formed.

A screw cap (14, 502) configured to be removably attachable to a bottle (12) includes a base (40) and an annular skirt (42, 508) extending downwardly therefrom. One or more threads (32) extend radially inwardly from an interior surface of the skirt (42, 508). A retention feature (509) extends radially inwardly from the interior surface of the skirt (42, 508). The retention feature (509) is configured to produce at least one of an audible response or a tactile response when the cap (14, 502) is rotated with respect to a bottle (12).

A tamper-evident closure comprising a cap and a retaining ring, the retaining ring is connected to the sidewall by a plurality of bridges, at least one of the bridges is frangible and at least one of the bridges is non-frangible whereby to form a link between the ring and the sidewall.

An apparatus and a method are provided for a container cap comprising a plurality of tamper evidence bridges configured to provide evidence that the container cap has been removed from a container by other than a manufacturer of the container. The tamper evidence bridges comprise a small tab of material that extends from a bottom-most edge of the container cap to a neck ring of the container. The tamper evidence bridges are configured to break, or snap, when the container cap is rotated relative to the neck ring. Broken tamper evidence bridges provide readily visible evidence to an end-user of the container that the container cap has been removed by other than the manufacturer of the container. The high visibility of the tamper evidence bridges serves to discourage vendors from attempting to refill and resale of the used containers.

A closure includes first and second closure portions. The first closure portion includes a polymeric top wall portion and an annular skirt portion. The skirt portion includes exterior and interior surfaces. The interior surface includes an internal thread formation for mating engagement with an external thread formation of a container and at least one rotation-inhibiting projection. The rotation-inhibiting projection is located to contact the external thread formation. The rotation-inhibiting projection is in the general shape of the letter “C” prior to engagement with the external thread formation of the container. The second closure portion includes a polymeric tamper-evident band.

Cap for drink bottle or similar recipient that comprises a base element comprising a drinking nozzle and a substantially tubular portion adapted to be secured to a neck of the bottle or recipient, a covering element comprising a flip top adapted to hermetically seal the drinking nozzle of the base element, and anti-tamper means of the top adapted to provide a visual indication of whether the top has already been removed for a first time from the drinking nozzle; the covering element comprises a tubular portion adapted to be secured to the outside of the substantially tubular portion of the base element, and the anti-tamper means of the top comprise an interlocking element extended from a lower edge of the top; wherein, the interlocking element is adapted to latch through the inside a front window of the tubular portion.

A closure device for firing an additive into a carbonated beverage bottle with a neck comprises a cap member and a housing. The cap member includes a pressurised tank containing the additive and a propellant and has a bottom aperture. The housing engages with the neck and includes a plug member which engages with the bottom aperture. The cap member can be lifted relative to the housing from a first armed or closed position in which the plug member closes the bottom aperture to a second firing position in which the plug member provides a communication path from the tank through a nozzle in the plug member.

A tamper-evident closure (10) for a container mouth, comprising a cap and a retaining ring arranged under the cap for retaining the closure on the container, the cap is separable from the ring, the cap and ring are joined by a pair of arms (37, 39), the arms are non-frangibly connected to a common root (40) at one end, the other end (36) one of the arms is non-frangibly connected at a circumferentially clockwise location from the root and the other end (38) of the other arm is non-frangibly connected to a circumferentially anticlockwise location from the root, whereby the arms permit axial separation of the cap from the ring and assume a generally V-form configuration when doing so and whereby the cap remains tethered to the ring.

A tool for manufacturing a cap for a container comprises a blade set that includes a plurality of knives. The knives are configured to make incisions in a cap having a main body having a top plate and a circular sidewall. The top plate has a top surface, wherein two opposite sides of the circular sidewall circularly connect to each other, one periphery of the circular sidewall connects to one surface of the top plate forming a closed end, and the other periphery of the circular sidewall at the opposite side of the closed end forms an opened end and a ring member, which is located at the opened end of the main body. There is a first tab on the ring member and a second tab on the sidewall.
