A near field magnetically coupled contactless device includes a foldable substrate in the form of a tape; two metal surfaces located facing each other on opposite sides of the substrate in a region of interest of the substrate, configured such that a piercing of the region of interest causes a permanent short circuit between the two metal surfaces; and a circuit configured to detect a short circuit between the two metal surfaces.

An NFC tag includes a foldable substrate in the form of a tape; an antenna located at a first end of the tape; a capacitor connected to the antenna, located at the first end of the tape; an impedance, in particular a capacitor, located at a second end of the tape; and conductive tracks running along the tape to connect the impedance to the antenna.

A near field magnetically coupled anti-counterfeiting tag comprises a control microcircuit configured to implement a basic function and a cryptographic function; a sacrificial conductive track located across a sacrificial area of the tag; and a circuit for detecting continuity of the sacrificial track, cooperating with the microcircuit to implement the basic function without implementing the cryptographic function when the sacrificial track is broken.

A near field magnetically coupled contactless device, comprises a foldable substrate in the form of a tape; an antenna circuit tuned to a nominal frequency, including an antenna and a capacitor connected to the antenna; a sacrificial impedance connected to the antenna circuit to contribute to the tuning of the antenna circuit to the nominal frequency; and a sacrificial structure comprising a conductive track connecting the sacrificial impedance to the antenna circuit, configured in meanders occupying a region of interest of the substrate such that a piercing of the region of interest severs the conductive track.

A method of preparing a closure for a product retaining container is disclosed along with the closure that is obtainable by the method. The present disclosure also relates to a use, in the manufacture of a closure, of a knife blade comprising a cutting edge region having a discontinuous cutting edge.

A liquid-containing container is the liquid-containing container containing a liquid and includes a container body with an opening portion and a stopper that closes the opening portion and has oxygen permeability. The stopper includes a stopper body portion and a barrier layer provided on at least part of a surface of the stopper body portion. The barrier layer constitutes at least a surface of a portion of the stopper to be inserted into the container body and a surface of the stopper defining a storage space for the liquid and includes at least one selected from the group consisting of a p-xylylene layer, a diamond-like carbon layer, and a fluoropolymer layer.

A closure for a product retaining container constructed for being inserted and securely retained in a portal forming neck of the container has a substantially cylindrical shape and substantially flat terminating surfaces forming the opposed ends of said closure, wherein at least one of said terminating surfaces is at least partially covered by a decorative layer. Indicia may be applied on at least one of the two substantially flat terminating surfaces forming the opposed ends of a closure by means of hot stamping.
