A materials containment canister comprising a lower cap with an upper thread, a body with multiple interior chambers and an upper cap with a lid, optional handle and orifice. The upper cap is capable of rotating to allow for the orifice to access individual chambers which can store materials.

Disclosed is a packaging box including a box body and a box lid, the box lid including a lid body and a first bent portion, the box body having a box opening, the box lid being provided at the box opening, where the box opening is provided with a second bent portion; when the box body and the box lid are closed and looking up the packaging box, a bottom end face of an outer side wall of the first bent portion is invisible; the box lid is provided with a first locked portion, the box body is provided with a second locked portion corresponding to a lower side of the first locked portion; and the lid body is provided with an inspection window. The packaging box solve the problem that the articles in the box would be missing and facilitate the personnel to inspect the articles within the box.

A storage box for property storage having an open box side surrounded by an upper edge and closed by a lid engaged to the box edges to prevent the box from disengaging from the lid. The lid surroundingly engaging the upper edge of the box along a horizontal box flange around the perimeter of the open box side. A vertical box flange on three sides of the horizontal box flange surrounding the upper edge. A lid on the storage box. The lid having a box edge rail engagement for surroundingly and removably engaging the vertical box flange of the storage box.

Disclosed is a test barrel, to prevent a test liquid in the barrel from sputtering into a connection gap due to shaking of the barrel to hence cause contamination, improve the measurement accuracy in case of multiple tests, and meanwhile improve the operability of screwing on and screwing off the entire device during use of the device. The above technical objective of this utility model is implemented by employing the following technical solution: a test barrel, comprising barrel lid and a barrel body; wherein the threaded rings are arranged on an inner wall of a side face of the barrel lid and an outer wall of an opening of the barrel body, a rotary force applying portion is arranged on an outer wall of the side face of the barrel lid, and during engagement, a liquid blocking washer is arranged between the barrel lid and the barrel body, wherein a radial width of the liquid blocking washer is greater than a thickness of the opening of the barrel body.

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 storage delivery box is provided. The storage delivery box includes a housing having a base, sidewalls, a lid, and an interior volume. The lid is hingedly attached to the housing for selectively providing access to the interior volume. The lid includes a locking mechanism configured to automatically secure the lid when in a closed position. A door lock disposed on the lid includes an input for unlocking the lid when in the closed position. An alarm system disposed on the housing is configured to detect intruders, activate a home alarm system and a recording device, and wirelessly communicate any attempted intrusions to an electronic device. An auxiliary net removably attachable to the interior volume is configured to receive items that are too large to fit within the interior volume and secure them exteriorly to the storage box.

A child-resistant molded-fiber container includes a base, a lid, and a hinge. The base includes an upper surface and a lower surface. The upper surface defines a cavity and the lower surface defines a channel surrounding the cavity. The channel is disposed between an inner sidewall and an outer sidewall of the base. The outer sidewall includes a locking member. The lid includes a sidewall having an opening. The hinge rotatably connects the base and the lid, and allows rotation of the lid between an open configuration and a closed configuration relative to the base. In the closed configuration, the sidewall of the lid is disposed around the outer sidewall of the base and conceals the upper surface of the base. In the closed configuration, the locking member of the base extends through the opening of the lid to inhibit movement of the lid to the open configuration.

A drinking vessel having a container with a hollow interior and a lid. The lid is connectable to the container and having an upper lid portion and a lower lid portion. The upper lid portion has a top surface and a drinking aperture located at the top surface. The lower lid portion includes a twist ring rotatable with respect to the upper lid portion. The lid also includes a sealing mechanism mechanically coupled to the twist ring so as to move between a closed position in which the sealing mechanism seals the drinking aperture and an open position in which the sealing mechanism unseals the drinking aperture. Further, the lid includes a spring mechanism mechanically coupled to the twist ring. When the twist ring is in its initial position, the sealing mechanism is positioned in the closed position sealing the drinking aperture, and when the twist ring is rotated into a first open position, the sealing mechanism is positioned in its open position and the spring mechanism is biased to return the twist ring into its initial position.

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.
