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.

Disclosed is a cover body structure and a bottle thereof. The cover body structure includes: a rotary cover, a dust-proof cap, a driving assembly, and a toggle member. The rotary cover is provided with a straw and the dust-proof cap is rotatably connected to the rotary cover, to enable the dust-proof cap and the rotary cover to have a buckled state and a flip state. By connecting one end of the driving assembly to the dust-proof cap, rotatably disposing the toggle member on the rotary cover, and rotatably connecting the other end of the driving assembly to the toggle member, the toggle member can be driven to enable the toggle member to rotate to a liquid path blocked state in which the straw is bent in the buckled state and rotate to a liquid path conducted state in which the straw is rebounded and restored in the flip state.

A secure beverage container may include a body having a first end, a second end opposing the first end, a first longitudinal side extending between the first end and the second end, and a second longitudinal side opposing the first longitudinal side and extending between the first end and the second end, the first end being closed, the second end being open. The body may define a cavity to receive a beverage fluid. The secure beverage container may include a lid to be received by the second end to seal the cavity in the body, and a powered locking device. The secure beverage container may include an access control device coupled to the powered locking device and configured to cause the powered locking device to switch between the locked state and the unlocked state based upon a security token.

Provided is a portable insulated lunch box, including: a box body (1) and a cover body (2) adapted to the box body (1); the cover body (2) defines a mounting cavity (4) passing vertically through the cover body (2), an upper opening of the mounting cavity (4) is arranged with a pressing member (5), and multiple locking members (6), that are transversely, elastically, and movably connected, are arranged in the mounting cavity (4); an outer end of each locking member (6) passes through a cavity wall of the mounting cavity (4), and an inner end of each locking member (6) is arranged with an internal push bevel (7) matched with a lower edge of the pressing member (5); an inner side wall of the box body (1) is arranged with multiple clamping grooves (8) each matched with the outer end of a corresponding locking member (6).

A secure beverage container includes a body having a first end, and a second end opposing the first end. The secure beverage container includes a lid assembly to be received by the second end. The lid assembly includes a lid housing, a sipper carried by the lid housing, a latch carried by the lid housing and configured to selectively latch to adjacent portions of the body, and a mechanical assembly carried by the lid housing and coupled to the sipper and the latch. The mechanical assembly is configured to operate in one of a locked state, and an unlocked state. The lid assembly also includes an access control device carried by the lid housing and coupled to the mechanical assembly, the access control device configured to cause the mechanical assembly to switch between the locked state and the unlocked state based upon a security token.

The present disclosure provides a container and a cap assembly. The container includes a component having an opening, and the cap assembly. The cap assembly includes a cap and an elastic arm. The elastic arm is disposed on the cap and extends obliquely with respect to a radial direction of the cap. At least a portion of the elastic arm is capable of being received in a recess and abuts against a second protrusion to prevent the cap assembly from rotating in a first direction relative to the component having the opening, such that the cap assembly is locked with the component having the opening; and the at least a portion of the elastic arm is capable of being released from the recess to unlock the component having the opening. The cap assembly of the present disclosure is capable of engaging with the component having the opening, such that the cap assembly cannot be unlocked without a specific tool (e.g., an operating tool).

Provided is a portable insulated lunch box, including: a box body (1) and a cover body (2) adapted to the box body (1); the cover body (2) defines a mounting cavity (4) passing vertically through the cover body (2), an upper opening of the mounting cavity (4) is arranged with a pressing member (5), and multiple locking members (6), that are transversely, elastically, and movably connected, are arranged in the mounting cavity (4); an outer end of each locking member (6) passes through a cavity wall of the mounting cavity (4), and an inner end of each locking member (6) is arranged with an internal push bevel (7) matched with a lower edge of the pressing member (5); an inner side wall of the box body (1) is arranged with multiple clamping grooves (8) each matched with the outer end of a corresponding locking member (6).

A liquid chemical applicator used for scalp care is provided. The liquid chemical applicator includes a container accommodating liquid chemical, an inner cap coupled to the container, and an outer cap rotatably and movably coupled to the inner cap. The inner cap includes a bush portion coupled to an outlet hole of the container along a central axis of the outlet hole. The outer cap includes a plug portion blocking and opening the bush portion, and further discharges the liquid chemical introduced through the bush portion. The outer cap blocks or opens the bush portion by rotation in first and second rotation directions centered on the central axis and by movement in first and second movement directions along the central axis.
