The present invention relates to tethered plastic stopper having a closure shell and a tamper band connected to the closure shell by bridges that connect a bottom edge of the closure shell to a top edge of the tamper band. The stopper includes a ridge forming a link that separably connects the closure shell and the tamper band by a weakness line containing a plurality of first bridges and the at least one second bridge. The at least one second bridge has a cross-sectional area greater than the cross-sectional area of the first bridges. The link is formed by a separation line made along the bottom of the link and the top remaining material of the tamper band, the link remaining attached to the tamper band by the at least one second bridge when the plurality of first bridges is broken.

The present invention relates to tethered plastic stopper having a closure shell, a tamper band, and an annular ring. The annular ring is formed between a bottom weakness line separably linked through bottom bridges to the top edge of the tamper band and to the bottom edge of the annular ring and a top weakness line separably linked through top bridges to the top edge of the annular ring and to the bottom edge of the closure shell. At least one of the bottom bridges is configured to prevent disconnection of the annular ring from the tamper band and at least one of the top bridges is configured to prevent disconnection of the annular ring from the closure shell. The remaining bottom bridge and the remaining top bridge having a section exceeding at least 30% relative to the section of the bottom bridges and top bridges, respectively.

Described is a cap (1) for a container (2), 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 (302) 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 (301) and the closing element joined; wherein the retaining ring comprises a joining portion (305) at which the retaining ring is joined to the closing element; a first connecting band (306), which extends from a first end zone of the joining portion to the retaining portion (303), and a second connecting band (307), 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 (308), interposed between the first connecting band (306) and the second connecting band (307) 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 (201). A method is also provided for making the cap in a cutting unit.

A closure cap for closing a pouring opening of a container has a cylindrical threaded part with an open rim an inner thread configured to cooperate with an outer thread of a container neck, a security ring configured to be held on a projection formed on the container neck, a plurality of security webs configured to releasably connect the security ring to the open rim, and a first retaining strip having a first end securely connected to the open rim of the threaded part and a second end securely connected to the security ring. The closure cap has a second retaining strip having a third end securely connected to the open rim of the threaded part and a fourth endue securely connected to the security ring. A circular web section is formed between the first and the second ends. A second projection is formed on an outer wall of the web section.

Described is closing cap for a container comprising a lateral wall extending about an axis, a separation line being provided on the lateral wall to define a retaining ring, which comprises a retaining portion which extends up to a free edge of the retaining ring and is configured to engage internally with a ring for locking a neck of the container in such a way as to remain anchored to the neck, and a closing element removably engageable with the neck, so as to open or close the container rotating the closing element about the axis. The separation line is circumferentially interrupted to define in the lateral wall a joining zone in which the retaining ring and the closing element are joined. The cap comprises in addition an incision line, which is also provided on the lateral wall to define, in association with the separation line at least a first connecting band and a second connecting band for connecting together the joining zone and the retaining portion. The incision line comprises a pair of lateral stretches wherein a first lateral stretch defines, with a first part of the separation line, the first connecting band and a second lateral stretch defines, with a second part of the separation line, the second connecting band. The lateral stretches differ in angular extension to define connecting bands of different lengths, the angular difference between the longest lateral stretch and the other lateral stretch being greater than or equal to 5° and less than or equal to 45°.

An apparatus and methods are provided for a closure for sealing contents within an interior of a container. The closure comprises a closure portion that is coupled to a tamper evidence band by a single anchor. The closure portion threadably engages with a finish portion of the container and seals contents in the interior of the container. The anchor is configured to keep the closure portion coupled with the tamper evidence band when the closure portion is untightened from the finish portion. A multiplicity of thin connections between the tamper evidence band and the closure portion break apart when the closure portion is untightened from the finish portion. The anchor remains unbroken and allows the closure portion to be tilted away from the finish portion. The tamper evidence band includes a split portion that separates when the closure portion is pulled from the finish portion with sufficient force.

A closure for closing an opening defined by a finish of a container. The closure includes a main body and a tamper band. The tamper band is connected to the main body by a plurality of bridges. A hinge of the closure is configured to permit the main body to pivot relative to the tamper band.

A cap for a container comprises: a retaining ring intended to remain associated with a neck of the container; a closing element movable between a closed position and an open position; at least one connecting band for keeping the closing element connected to the retaining ring even in the open position. The retaining ring comprises engaging members suitable for engaging with the neck in order to prevent the retaining ring from being pulled off the neck. The engaging members comprise first engaging elements and second engaging elements which extend towards the inside of the retaining ring. The first engaging elements have a shape different from the second engaging elements, so as to be in contact with the neck in the open position, in order to obstruct rotation of the retaining ring around the neck.

The present disclosure describes bottle closure assemblies which are made at least in part with a polyethylene composition having good processability, good organoleptic properties and good dimensional stability. The bottle closure assembly includes a cap portion, an elongated tether portion, and a retaining means portion. The retaining means portions engages a bottle neck or an upper portion of a bottle. The elongated tether portion connects at least one point on the cap portion to at least one point on the retaining means portion so as to prevent loss of the cap portion from a bottle.
