A closure for a flexible thin-walled packaging is provided. The closure has a rigid overcap, applicable directly or indirectly to a spout of the flexible thin-walled packaging, made of a first plastic material, a collar suitable for being inserted on a grip portion of the spout, and a flexible lace connecting the collar to the rigid overcap. The flexible lace is made by bi-injection, together with the overcap and the collar, of a second plastic material, different from the first plastic material.

A cap for a container includes an annular tamper evident band with a generally rigid cylindrical frame having an upper ring and a plurality of ribs extending axially from the ring and spaced circumferentially apart about the ring. A plurality of retainer elements are supported by the frame, each retainer element connected at circumferentially opposed ends by resiliently flexible webs to adjacent ones of the ribs. The retainer elements are biased to a radially contracted position, in which the retainer elements protrude inwardly to engage an underside surface of a neck flange of the container. The retainer elements are movable to a radially expanded position in which the retainer elements can be advanced axially past the neck flange when installing the cap onto the container for the first time.

A container preform for forming a plastic container includes a neck with a finish portion including an opening and one or more threads disposed on the finish portion for rotatably engaging with a closure to seal contents within an interior of a container formed from the preform. At least one of the one or more threads includes a main thread body, and a thread start configured to guide a thread of the closure into engagement with the main thread body. The thread start being biased towards the opening.

A container assembly includes a plastic container and a tethered closure. In embodiments, a tethered closure includes a cap, a tamper evident band, a plurality of breakaway connectors, and a connecting portion. The plurality of breakaway connectors connect the tamper evident band to the cap. In embodiments, the connecting portion connects the tamper evident band to the cap, and maintains the connection of the cap to the tamper evident band after the separation of the breakaway connectors from the cap.

A closing cap for closing a container comprises a cylindrical threaded part having an open edge and an internal screw thread, which can interact with an external screw thread of the container neck. A tamper-proof strip is configured to be retained on an annular protrusion formed on the container neck. A retaining strip has a first and a second end and a first and a second edge. The first end is fixedly connected to the open edge of the threaded part, and the second end is fixedly connected to the tamper-proof strip. The first edge is detachably connected to the open edge of the threaded part by a predetermined breaking element, and the second edge is detachably connected to the tamper-proof strip by a second predetermined breaking element. The first predetermined breaking element and the second predetermined breaking element have different tensile strengths or tear strengths.

A compact cap with an opening block, after opening, for a container having a mouthpiece, includes a base ring preventing separation from the mouthpiece, a protective cap or cover for opening and closing the mouthpiece, a hinge arrangement that makes the base ring and the cover integral, and frangible bridges, which connect a lower edge of the cover with an upper edge of the base ring when the cover is closing on the ring base and the mouthpiece. The hinge arrangement includes a plurality of spaced strips or bridges, which connect the cover and the base ring, and an extension enlarged outwardly, which forms an integral part of an annular collar and is obtained at the lower end of the cover, and which becomes engaged with the mouthpiece when the cover is rotated from a closed position to an open position to provide a stable open position of the cover.

A canister includes a closure configured to mount on a container to close an open mouth into a product storage region formed in the container. The closure includes a lid and a lid retainer coupled to the lid. The lid retainer is configured to mate with an external thread on the container to retain the closure in a mounted position on the container.

The invention relates to a closure consisting of a screw cap (10) with a tamperproof strip (3). The screw cap has at least one cylindrical cap casing (2) with an inner thread and a circumferential tamperproof strip at the lower open end of the cap casing, said tamperproof strip being connected to the lower edge of the cap casing along easily tearable weakness lines (13, 14), wherein the tamperproof strip remains captively connected to the cap casing after a tearing process along the weakness lines by means of holding strips (15, 16). The aim of the invention is to design a captive screw cap with a tamperproof strip in such a manner that after the screw cap has been unscrewed and released from the bottleneck opening, the screw cap is folded away or tilted into a position in which the screw cap does not interfere with the additional use of the bottle or with pouring or drinking out of the bottle and can remain there without additional measures. According to the invention, this is achieved in that the holding strips are formed by two weakness lines, each of which is interrupted at least once in the circumferential direction and which partly overlap in the circumferential direction and run at an axial distance to each other at least in the overlap region. The separating web (11, 12) of each of the two weakness lines is bridged by the respective other weakness line preferably at an axial distance.

A closure for a container includes a top panel, a skirt depending from the top panel and extending circumferentially about a central axis, a tamper-evident band attached to the skirt, and at least one thread extending from an interior surface of the skirt. The skirt extends from a first end attached to the top panel to a second end opposite the first end. The skirt is tapered radially outward from the first end to the second end such that a diameter of the skirt at the second end is greater than the diameter of the skirt at the first end.

Described is a cap for a container, a combination of a closing cap for a container and a neck of the container and a relative method for making the cap for the container.

The cap comprises a lateral wall extending about an axis and a transversal wall positioned at one end of the lateral wall, a separation line being provided on the lateral wall to define a retaining ring, which is configured to remain anchored to a neck of the container and which extends up to a free edge; a closing element removably engageable with the neck, so as to open or close the container; the separation line extends about an axis and being circumferentially interrupted to leave the retaining ring and the closing element joined; wherein the retaining ring comprises a joining portion at which the retaining ring is joined to the closing element; a first connecting band, which extends from a first end zone of the joining portion to the retaining portion, and a second connecting band, which extends from a second end zone of the joining portion, the second end zone being positioned circumferentially on the opposite side to the first end zone; a tab, interposed between the first connecting band and the second connecting band and being protruding, or aligned with respect to it, so that, when the closing element is in an open condition and the connecting bands keep the closing element connected to the retaining ring, the tab can rest on the neck. A method is also provided for making the cap in a cutting unit.
