The present disclosure relates generally to containers and container lids. In at least one embodiment, the disclosed containers and container lids provide a liquid-tight seal with the inclusion of a separately attached ring that generally eliminates material-trapping seams. For example, in certain embodiments, a container and a container ring for attaching to the rim of the container is disclosed. In these embodiments, the container ring attaches to the rim of the container such that a liquid-tight vertical seal is formed, thereby reducing or eliminating material-trapping seams.

Disclosed are a container cover and a vacuum preservation container. The container cover comprises a cover body and an air extraction assembly, wherein a first through hole is provided in the cover body, the air extraction assembly comprises an outer cover and an inner cover, the inner cover is arranged on an upper end of the first through hole in a sealing manner, a second through hole and a third through hole are provided in the inner cover, the second through hole is in communication with the first through hole, a first one-way valve is arranged in the second through hole, and a second one-way valve is arranged in the third through hole.

A packaging comprising, a container made of plastic and comprising lateral walls, an upper opening and a bottom and, on the other hand, a lid that is made of plastic, is detachable and is configured to cover the upper opening of the container, and in which the container is provided at its upper opening with a first engagement portion bearing an outwardly directed ridge running around the periphery, said lid being provided on its peripheral part with a second engagement portion that extends folded downward and provided with an inwardly directed ridge which is able to latch underneath the outwardly directed ridge of the container, and in which the second engagement portion of the lid has a skirt with a skirt section that can be folded back and that bears a lug which is able to latch onto a second outwardly directed ridge of the container.

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 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.

It is desired to make an improved lid suitable for pails, overcoming the problem of existing complexities and leaks. The invention is achieved by a lid (300) having a lid skirt (320) provided with an inner collar (328) that engages an outer collar (222) of a sidewall (220) of a pail (200), the lid skirt (320) being provided with a fastening mechanism (330) for tightening the inner collar (328) around the sidewall (220) below the outer collar (222). Corresponding to the lid (300) a pail (200) is provided having a simplified structure that is supported mechanically by the lid (300). Furthermore, a thermally insulated compound pail is disclosed, the compound pail comprising a first inner pail (200) that is inserted into a second outer pail (200) such that a space (404) is formed between said pails (200).

A disposable waterproof paper covers for plates and cups. The disposable waterproof paper covers have a corrugated circumferential rim that is designed to wrap the rim of the plate or the cup from its underside.

A container system having a base and a lid. The base has a bottom and one or more sidewalls extending from the bottom to define an interior volume, the base having a rim at a peripheral edge of the one or more sidewalls, the rim defining a first engagement region. The system also has a lid having a peripheral outer rim defining a second engagement region, the first and second engagement regions dimensioned to releasably engage with each other. The lid has a hinged region having a first hinge about which the lid folds as a first part of the lid is lifted from the base to disengage portions of the first and second engagement regions from one another, to provide access to the interior volume of the base while a second part of the lid on an opposite side of the hinge remains secured and attached to the base.

A cover structure is disclosed. When an annular sealing portion of a cover body is engaged with a container, a sealing section of the annular sealing portion abuts against an annular inner surface of the container, and then, a folding section of the annular sealing portion is folded to a sealing state, so that part of the folding section abuts against the annular outer surface of the container to form a dual leak-proof sealing structure. The folding section of the annular sealing portion is an annular elastic and full-peripheral tightening structure. Therefore, the sealing between the container and the cover may be strengthened for a good sealing effect, and preventing liquid in the container from being splashed on surrounding articles. When the folding section is in the unsealing state, the cover can be separated from the container, which is convenient to carry and use.

A container is disclosed that has a base and a lid that is rotatable about a hinge from a closed configuration to an open configuration. The lid may be secured to the base with a latch assembly. A latch assembly may have a locked position and an unlocked position, where the latch assembly includes: a latch body pivotally connected to the lid, a latch button slidably connected with the latch body, the latch button having a latch button-locking member, a latch-locking arm pivotally connected to the latch body, and a latch-locking arm biasing member that exerts a rotational force on the latch-locking arm. When the latch assembly is moved to the locked position, the latch-locking arm may engage the base and rotate against the rotational force from the latch-locking arm causing the latch button to move against the linear force until the latch button-locking member engages the arm-locking member.
