Disclosed is an airtight container having a deformable cover unit or a deformable container unit, which ensures easy maintenance of the cover unit and allows the cover unit to be easily used with a large-capacity fixed container unit, or which includes an expandable accommodating space or an expandable inlet to accommodate various sizes of storage items therein in an airtight manner. The airtight container includes a deformable cover unit for useable with a fixed container unit. Alternatively, the airtight container includes first and second frames pivotably connected to each other so as to be selectively coupled to or come into contact with each other in order to seal a contact or coupling portion therebetween, and a deformable container unit disposed over the frames and configured to provide an accommodating space for a storage item therein. The first and second frames are disposed along the inlet rim of the container unit.

A food storage assembly is provided. The food storage assembly includes a container including a base and an opening defining a rim, wherein a side wall is circumferentially disposed between the base and the rim. The food storage assembly further includes an insert having a base, wherein the insert includes two or more side portions connected to the base and extending radially therefrom, wherein the two or more side portions are flexible and are folded to form a side wall conforming to a shape of the side wall of the container when the insert is positioned inside the container.

A coaster is structured to be coupled to a conventional cup, such as an iced beverage cup, using a conventional cup sleeve. The coaster includes a generally disk shaped base having an outer perimeter. Two or more elongate tethers extend outwardly from the outer perimeter of the base. The coaster assumes a combination-ready configuration with the two or more elongate tethers extending generally upright and outwardly to a same side of the base, in such a way that the coaster fits snugly within a conventional cup sleeve. In a final combination configuration with a cup sleeve, the coaster combines with the cup sleeve to create an insulating and water absorptive coaster and sleeve, frictionally and snugly coupled to the cup in a robust manner to make the coaster highly portable together with the cup and cup sleeve, and configured to collect condensation formed on the exterior surface of the cup.

An enclosure for covering an outer surface of an object includes a flexible panel moveable between a first position and a second position. The flexible panel is adapted to be flat in the first position and to at least partially enclose the object in the second position. The flexible panel includes a first panel edge, a second panel edge, and a closure system. The first panel edge is spaced apart from the second panel edge. The closure system includes a plurality of tabs extending from each of the first and the second panel edges. At least one of the plurality of tabs is adapted to simultaneously engage with two other adjacent tabs. In the second position, the closure system interconnects the first and second panel edges.
