A closure for a spout of a thin-walled flexible package has a cap and a tamper evident seal having a tamper evident ring suitable for being applied to the spout, a tamper evident portion integral with the cap, and at least one breakable bridge which, when the tamper evident seal is unbroken, joins the tamper evident ring to the tamper evident portion. The tamper evident ring has an upper face that delimits the tamper evident ring at the top, the upper face consisting of a wavy surface having circumferentially successive ridges and valleys, each valley having a bottom surface. The tamper evident portion has at least one tamper evident tooth having a top face that is contained in a respective valley. The at least one breakable bridge joins the bottom surface and the top face and is contained in the valley.

Closure for a spout in a thin-walled package

A closure for a spout of a flexible thin-walled packaging is provided. The closure has a base body having an irreversibly yielding guarantee wall, a cap assembly having a cap and a guarantee tab, at least one breakable bridge, and a flexible hinge that joins the base body to the cap assembly. The at least one breakable bridge, in an intact closed configuration, is integral and joins the guarantee tab to the guarantee wall.

Closure for a thin-walled packaging provided with a spout

A closure for a spout of a thin-walled flexible package is provided. The closure has a cap having a cap wall having a cap axis extending between a cap lower end and a cap upper end, a tamper-evident seal, and a grip surface having an undulated grip surface edge having a succession of low sections and high sections, such that bulges and windows are formed on the grip surface. The windows are sufficiently wide circumferentially to contain the cap and the tamper-evident seal in width. The low section of the undulated grip surface edge is tangent inferiorly to an imaginary plane orthogonal to the cap axis, which axially delimits inferiorly at least one of the bulges. The imaginary plane is arranged axially below the cap lower end.

Closure for a straw of thin-walled flexible packaging

A cap for a spout of a flexible thin-walled packaging is provided. The cap has a closure body having an annular closure wall extending along a main axis between a lower end and an upper end. An extension ending with a base is placed at a predefined height below the lower end of the annular closure wall. A scraper element is arranged along the extension to remove any residue of product in the spout.

Closure for containers

A closure for a spout has a closure body having an annular body wall extending along a main axis between a closure base and an annular body wall edge. The closure is screwable to a spout having a connecting portion, suitable for welding to thin walls of a package, and a tube protruding from the connecting portion along a spout axis and ending with a mouth. The tube has a gripping section having a guide ring. Connection means connect the closure to the spout even when the closure is unscrewed. The connection means have a collar inserted on the gripping section of the spout and axially bound thereto by the guide ring, and an at least partially flexible tie that joins the collar to the closure.
