A wet sheet storage container. A plurality of male thread parts for screwing a lid body in the circumferential direction are formed on the outer circumferential surface of an upper end part of a container body, and a plurality of female thread parts for threadedly engaging with the male thread parts are formed on the inner circumferential surface of the lid body. The male thread parts are each provided with a base end part formed on the upstream side in the rotation direction of the lid body during installation of the lid body, and a tip end part formed on the downstream side in the rotation direction of the lid body, and the male thread parts are formed such that the height of the tip end part is greater than the height of the base end part.

A reusable vessel comprises a first compartment to store therein a substance and a second compartment separated from the first compartment by a boundary element comprising a wall or membrane having one or more apertures therein. A valve is movable between a closed position, in which the valve seals the one or more apertures, and an open position allowing the substance to be released from the first compartment into the second compartment, or a substance in the second compartment to mix with the substance in the first compartment. A triggering mechanism is coupled to the valve to move the valve between the open and closed positions. The triggering mechanism comprises one or more external elements coupled to one or more internal cam elements to control the valve, which, when triggered causes the one or more external elements to exhibit a visible change to indicate the open and closed positions of the valve.

A container lid is provided herein having structurally reinforcing ribs therein. The ribs increase the strength of the lid across a central region thereof. Specifically, the lid can have an outer perimeter and the ribs can be spaced inwardly from the outer perimeter. The inwardly spaced ribs can provide a distinct look for consumer differentiation. Additionally, the ribs can be arcuate so that they generally follow a curvature of the outer perimeter of the lid. As such, a label region within the lid central region is preserved, while the lid is still strengthened by the ribs.

A moisture tight container (100, 300) includes a container body (101, 301) and a lid (101, 120, 320) preferably linked to the body (101, 301) by a hinge (140, 340). The body (101, 301) and lid (101, 120, 320) include at least a first seal (462) and a second seal (464) in series to provide a moisture tight seal (460) between the body (101, 301) and the lid (101, 120, 320). The first seal (462) includes mating of thermoplastic-to-thermoplastic sealing surfaces of the body (101, 301) and lid (101, 120, 320) respectively. The second seal (464) includes mating of thermoplastic-to-elastomeric sealing surfaces of the body (101, 301) and lid (101, 120, 320), respectively, or of the lid (101, 120, 320) and body (101, 301), respectively.

The present invention relates to a recognition system for recognizing containers to be filled with a given type of product, wherein the containers are equipped with a device for closing and opening the mouth through which the product to be introduced into the container is designed to pass. The closing and opening device is equipped with NFC electronic identification means. A corresponding reading and writing device for reading and writing said NFC electronic identification means is provided in the station for filling of the container and, in view of accommodating the container and the device for closing and opening its mouth, such station is conformed with at least the area configured to receive the device for closing and opening the mouth having a three-dimensional shape that mates the three-dimensional shape that the closing and opening device assumes when it is open to allow the container to be filled and/or emptied through the mouth.

Disclosed is a sealed food can with time setting device, which comprises a can body and a sealing cover sealingly connected with the can body through a plurality of locks on the periphery of the cover. A time setting device comprises a sliding rail and an indicating slider being slidable along the sliding rail. Several date marks are arranged at equal intervals beside the sliding rail. The indicating slider has an indicating tip on the side corresponding to the date marks. The indicating slider moves along the sliding rail so that the indicator tip corresponds to one of the date marks. The time setting device of the present invention can set the time when the food is stored or the expiration time, which is convenient for consumer to accurately manage the food storage time, and is simple in structure, intuitive in display and convenient in use.

A container includes a base, a cover and an intermediate part. The base includes a first room and a first lip extends from the open top of the base. The cover includes a second room and a second lip extends from the open bottom of the cover. The intermediate part includes a third room and a third lip extends from the open top of the third room. The cover is mounted to the base with the intermediate part located between the cover and the base. The cover seals the base and the intermediate part by one-time pressing action. The base includes at least one plate which is engaged with a recess formed to the outside of the second lip of the cover to secure the cover to the base.

A bowl and lid set includes a lid member that has a top lid wall and a first surrounding wall extending downwardly from the top lid wall, and a bowl member that includes a bottom wall and a side wall extending upwardly from a periphery of the bottom wall. The side wall has an upper engaging portion that is made of an elastic material and that is deformable from a non-deformed state, where the bowl member is disengaged from the lid member and where a minimum inner diameter of the upper engaging portion is smaller than a maximum outer diameter of the first surrounding wall of the lid member, to a deformed state, where the upper engaging portion is resiliently stretched for tightly encircling the first surrounding wall.
