Described is an automated reagent mixing container for separately storing and automatically mixing together at least two stored reagent components.

A storage container for a cylindrical tube of viscous construction material includes a body dimensioned to receive a cylindrical tube of viscous construction material. A nozzle enclosure is attached to a top end of the body and is dimensioned to receive a nozzle of a cylindrical tube of viscous construction material. A gasket is positioned between the body and the nozzle that substantially prevents air in the body from entering into the nozzle enclosure. A base seals the cylindrical tube of viscous construction material in the body.

A cup/lid combination includes a sleeve disposed about an exterior surface of an open-top container for movement relative to the container. A first magnet is disposed adjacent to the open top for movement relative to the container. A link assembly coupled to the sleeve and to the first magnet causes the movement of the sleeve and the movement of the first magnet to be in opposing directions. A drinking lid disposed on the open top has a gravity-controlled closure element and a second magnet coupled to the closure element. The first and second magnets are positioned for magnetic interaction to thereby fix a position of the closure element when the sleeve is only subject to the force of gravity. The first and second magnets are positioned for no magnetic interaction when the movement of the sleeve opposes the force of gravity.

The invention relates to a stopper device with an external cap made from plastic and an internal insert for fixing the device around the neck of the container. The sleeve of the cap forms a head, into which the insert may be introduced and permanently fixed and a skirt extending axially from the insert. According to the invention, contamination on the neck of the container may be limited and the appearance improved. Particularly at the base of the neck, the skirt essentially forms a frustum converging towards the axis of the sleeve on extending from the head, before the installation of the device around the neck, the frustum forming, at the end opposite the head, an internal surface to come into contact against the container neck under the influence of an elastic deformation of the sleeve as a result of the installation of the device around the neck.

An electronic cigarette sealing piece for adding liquid by injection, a liquid container and an electronic cigarette are provided. The electronic cigarette sealing piece for adding liquid by injection includes a silicone substrate and a Teflon coating layer coated on a surface of the silicone substrate, the silicone substrate has a thickness of 0.8-1.5 mm, and the Teflon coating layer has a thickness of 0.05-0.2 mm. The liquid container includes a liquid container main body provided with a liquid adding opening thereon, the liquid adding opening is provided with the electronic cigarette sealing piece for adding liquid by injection, the liquid container main body seals the liquid adding opening with the electronic cigarette sealing piece for adding liquid by injection, and the Teflon coating layer of the electronic cigarette sealing piece for adding liquid by injection is provided at an inner side of the liquid adding opening. The electronic cigarette includes an electronic cigarette main body having the liquid container.

A storage box includes a box body having an opening, an upper cover and a side cover. The upper cover has an upper cover body covering removably an upper opening portion of the opening of the box body, a waterproof segment connected to a portion of a periphery of the upper cover body, and two pivot segments connected respectively to opposite ends of the waterproof segment. The side cover has a side cover body covering removably a side opening portion of the opening of the box body, and a pivot section connected pivotally to the pivot segments and having a side edge connected to a portion of a periphery of the side cover body. The pivot section is covered by and received in the waterproof segment of the upper body.

This is directed to systems and methods for cover assembly retention of a portable electronic device. In some embodiments, a cover assembly and/or housing of an electronic device can include one or more retention features such as detents, hooks, tabs, extensions, screw plates, screw holes, shuttles, latches, or any combination of the above, for retaining the cover assembly to the housing. In some embodiments, one or more retention features can be included on an internal platform of the electronic device to retain the cover assembly. In some embodiments, a hidden screw feature can be included in a SIM tray slot of the electronic device. Once a SIM tray has been inserted into the SIM tray slot, the screw feature can be hidden from sight and may become unapparent to an end user of the electronic device.

A lock catch structure and a storage box of chess pieces are provided. The lock catch structure includes a connecting buckle, a first fixing component, a lock cylinder, and a second fixing component. The connecting buckle is rotatably connected to the first fixing component, and the first fixing component is connected to a first end of a locked object. The lock cylinder is inserted into the second fixing component, and the second fixing component is connected to a second end of the locked object. The connecting buckle defines an accommodating cavity for accommodating the first fixing component and the second fixing component, the first fixing component and the second fixing component lock the first end of the locked object and the second end of the locked object.
