A closing cap for a container having a lateral wall and a transversal wall positioned at one end of the lateral wall, a separating line being provided on the lateral wall to define a retaining ring that is configured to internally engage with a stop ring of a neck of the container as to remain anchored to the neck, and a closing element removably engageable with the neck, so as to open or close the container. The separating 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 additionally includes an inner thread structure positioned on the inside of the lateral wall for engaging with an outer thread structure of the neck and removably coupling the closing element to the neck of the container.

Cap for container

A cap for a container comprises a side wall extending about an axis and a transversal wall arranged at an end of the side wall. A separation line is provided on the side wall for defining: The separation line extends about the axis and is circumferentially interrupted so as to leave a joining portion between the retaining ring and the closing element. The cap further has an incision line which extends transversally to the axis between the separation line and a free edge of the retaining ring, so that between the separation line and the incision line two connecting bands are defined, the connecting bands joining the retaining ring to the joining portion. The connecting bands have a radial thickness measured in a radial direction and a height measured parallel to the axis. The ratio between the height and the radial thickness of the connecting bands is greater than, or equal to, 1.4 and is less than, or equal to, 6.5.

Cap for closing a container, a combination of a cap and a neck

A cap for a container comprises a lateral wall extending around an axis and a transversal wall arranged transversally to the axis, a separating line being provided on the lateral wall to define: The separating line extends around the axis and is circumferentially interrupted for defining a joining portion which joins the retaining ring and the closing element. The cap further has an incision line which extends in the lateral wall, transversally to the axis, so that the separating line is axially interposed between the retaining ring and the incision line. Two connecting bands are defined between the separating line and the incision line to keep the closing element connected to the retaining ring.

Cap for closing a container

A closing cap for a container includes a separating line on a lateral wall forming a retaining ring, configured to remain anchored to a neck of the container and extending up to a free edge. A closing element is engageable with the neck, to open or close the container. The separating line is circumferentially interrupted to define in the lateral wall a joining zone, extending at a first angle, in which the retaining ring and the closing element are joined. An engagement element of the retaining ring is bent when the cap is closed. First and second incision lines allow deformability of a connecting portion and a region of the engagement element extending at a second angle, so that when first opening the closing element, the region goes beyond the locking ring and deforms to rest on the locking ring in an extended configuration.

Closing cap for a container

A cap for a container comprises: The closing element comprises a projection which projects from an outer surface of the lateral wall transversally to said axis, the projection extending around said axis by an angle of at least 180°.

Cap for a container having a hinge

A cap for a container comprises: 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.

Cap for a container, and a combination of a cap and of a container neck

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&#xb0; and less than or equal to 45&#xb0;.

A cap includes 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; 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, a first connecting band, and a second connecting band; 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.

Cap for a container, combination of a cap and a neck of the container and its production method

A cap for a container is provided and a related method for making the cap. The cap comprises a side wall extending about an axis and a transversal wall arranged at an end of the side wall, a separation line being provided on the side wall for defining: a retaining ring, which is intended to remain anchored to a neck of the container and is configured to internally engage with an enlargement of the neck; and a closure element which can removably engage the neck, so as to open or close the container. The separation line extends about the axis and is circumferentially interrupted so as to leave a joining portion, between the retaining ring and the closure element, which extends circumferentially for a respective angle, the cap further having an incision line which extends transversally to the axis between the separation line and a free edge of the retaining ring, so that two connecting bands are defined between the separation line and the incision line, the two connecting bands joining the retaining ring to the joining portion. The connecting bands are deformable and the joining portion is externally provided with a projection which projects from the joining portion and is positioned between a separation plane in which the separation line lies and the incision line so that, when the closure element is in the open position and the connecting bands keep the closure element connected to the retaining ring, an edge of the joining portion which, in the closed position, faces the retaining ring, is facing, in the open position, towards a rim of the neck and the projection is resting on the neck in said open position.

Closing cap for a container and its production method

A method for making products made of plastics comprises the steps of molding a piece made of polyethylene PE, or made of polypropylene PP, and mechanically folding in a guided manner a flap portion of the aforesaid piece at a folding temperature that is greater than ambient temperature ed less than the alpha-type intermediate physical transition temperature of the material. The method reduces the spring-back of the folded portion and the yield in the folding zone.
