An insert construction or formation is attachable to a basic lid construction for outfitting a hot beverage or liquid container assembly for enabling a user to enhance heat transfer from a relatively hot assembly-contained beverage or liquid prior to consumption. The insert construction or formation provides a damming structure located in adjacency to the primary liquid outlet of the basic lid construction for selectively transferring liquid intermediate a liquid-containing compartment and at least one beverage-cooling channel made part of the damming structure. Each beverage-cooling channel or formation directs liquid therethrough and transfers heat therefrom before the liquid exits the primary liquid outlet. The primary dam structure or insert construction thereby enables the user to redirect liquid movement via the basic lid construction for delaying liquid delivery via the primary beverage outlet and transferring heat therefrom prior to liquid consumption. Certain packaging methodology of the complex lid construction is further contemplated.

Stackable lids for a container each include a top surface facing generally in a first direction and a bottom surface opposite the top surface and facing generally in a second direction. Pivotable wing portions extend from each side edge of the lid and each pivotable wing portion is joined to its respective side edge by a hinge. The wing portions are moveable between engaged and disengaged positions, and an inner surface of each wing includes a tab member configured for detent engagement with a rim of the container. The lid also includes corner portions extending between the side edges. Each corner portion includes a skirt portion extending generally in the second direction. Each corner portion also defines a recessed shoulder configured to receive the skirt portion of another when the lids are stacked.

A foil of a tagger ring foil (TRF) closure system for a container, such as a can, is provided. The foil comprises a composite of two or more layers made from different materials instead of aluminum only.

A storage and transportation device, which relates to the technical field of storage and transportation apparatuses are disclosed. The storage and transportation device comprises a cover, a supporting plate and a sealant. The supporting plate covers an opening of the cover to form a space for accommodating an item to be transported. The storage and transportation device further comprises a first sealant groove and a second sealant groove arranged at a sealed junction between the cover and the supporting plate, the sealant is contained in each of the first sealant groove and the second sealant groove, and the two parts of the sealant are connected.
