The present disclosure relates generally to containers and container lids. In at least one embodiment, the disclosed containers and container lids include an improved seal structure that forms a liquid-tight seal. For example, in certain embodiments, the improved seal structure is included on a built-in ring around the rim of the container. In some embodiments, the improved seal structure is included on a separate container ring for attaching to a container. In these embodiments, the contents of the container may be poured out of the container such that virtually no excess content is trapped in-between seams.

Provided is a resin container lid in which a trouble such as a crack is prevented while maintaining easiness in opening even under a refrigerating or freezing environment, the resin container lid configured to be fitted to and detached from a resin container, the resin container lid including a flange part configured to be fitted to a container, the flange part being formed at a peripheral edge of the resin container lid, and an opening tab for detachment from the container, the opening tab projecting into an outer periphery from the flange part, with the tab having a flexural strength of 50 to 80 N under an environment of −30° C.

A container having a removable drain sensor configured to monitor one or more container parameters and/or one or more external container parameters. The drain sensor being configured to communicate with a remote device to enable remote monitoring of one or more of the parameters.

A container has an upper edge, a lateral wall extending around the circumference of the container, and an opening closed by a lid. A latching rim proximate the upper edge latches with a corresponding latching rim on the lid. The latching rims of the container and the lid, respectively, extend at least partially around a circumference of the same. The container lateral wall includes a peripheral skirt having a sub-region extending radially outwardly from the lateral wall. The lid includes a lower lid rim on the outside of the container and at least one extension extending outside the lateral wall of the container. The extension extends below the lower rim of the lid and at least partially penetrates the skirt of the container. The extension and the container include corresponding fixing devices releasable independently of the latching devices formed by the latching rims of the container and the lid.

Embodiments of the disclosure include an insulated drinking vessel comprising an inner wall surrounding an interior for containing a liquid beverage and an outer wall spaced from the inner wall to form an air space which acts to insulate the vessel interior in order to maintain the temperature of the liquid beverage contents within a desired range throughout a period of time which is normally required to consume the entire beverage contents. The insulated drinking vessel also includes a removable/resealable lid comprising at least one integrated tamper-evident sealed content dispensing opening which, when breached, allows the beverage contents to be removed while the lid remains attached to the vessel.

A container is described comprising: a base comprising a mouth, a first edge obtained around the mouth and a second edge connected to the first edge by a lower wall; a cover capable of being closed again on the base, the cover comprising a base wall and an edge connected to the base wall and adapted to be assembled with interference on the first edge of the base; the lower wall further comprising a breaking line along which the separation of the second edge from the first edge and from the base is adapted to occur to allow opening the container providing evidence of the occurred opening, the first upper wall of the first edge having sizes greater than those of the opening of the edge, to assemble with interference the first edge of the base inside the edge of the cover when the cover is closed on the base.

Embodiments of the disclosure include an insulated drinking vessel comprising an inner wall surrounding an interior for containing a liquid beverage and an outer wall spaced from the inner wall to form an air space which acts to insulate the vessel interior in order to maintain the temperature of the liquid beverage contents within a desired range throughout a period of time which is normally required to consume the entire beverage contents. The insulated drinking vessel also includes a removable/resealable lid comprising at least one integrated tamper-evident sealed content dispensing opening which, when breached, allows the beverage contents to be removed while the lid remains attached to the vessel.

A paper lid that is mainly made of paper includes a top plate portion extending in a first direction, an inner fitting portion extending in a second direction and being continuous with the top plate portion, a peak portion extending in a third direction and being continuous with the inner fitting portion, an outer fitting portion extending in a fourth direction, facing the inner fitting portion at a distance, and being continuous with the peak portion, and a flange portion extending in a fifth direction, being continuous with the outer fitting portion, and including an end of the paper lid.

A method for producing a paper lid includes a first step of holding down an outer edge area of a blank that is mainly made of paper, a second step of forming an inner fitting portion in a central area of the blank, while holding down the outer edge area, and a third step of forming an outer fitting portion in the central area, where the inner fitting portion is formed, while holding down the outer edge area.

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.
