A liftable hinge mechanism includes a base, a connecting component and a pin. The base has a narrow slot. The connecting component has an axle hole. The pin slidably passes through the narrow slot and rotatably inserts into the axle hole. The connecting component can be rotated and/or shifted relative to the base via the pin. A reciprocating engaging mechanism includes a shaft, a rotary plate, a first engaging component and a linkage module. The rotary plate is rotatably disposed on the shaft. The linkage module is connected between the rotary plate and the first engaging component. Rotation of the rotary plate drives the linkage module to move the first engaging component into a locking mode or an unlocking mode. The liftable hinge mechanism and the reciprocating engaging mechanism are applied to an airtight device with a housing and a cover capable of being folded and unfolded.

The present invention relates to a barrel lid, such as a wood wine barrel lid, that inhibits and withstands warping and/or deformation. In one embodiment, the anti-warping wine barrel head comprises a plurality of adjacent slats, a plurality of staves where at least one stave disposed between each pair of adjacent slats, a plurality of grooves disposed on a top and/or bottom surface of the barrel head where each groove is oriented at an angle with respect to the plurality of slats, and a plurality of rods disposed in the plurality of top and/or bottom surface grooves where at least one rod is disposed in each of the plurality of top and/or bottom surface grooves. In some embodiments, staves are double flanged or rectangular, and rods have a half-round cross-section or triangular cross-section. In other embodiments, a gasket may span the periphery of the barrel lid, for example, along a lip thereof. In some embodiments, a locking ring is utilized to secure wine barrel lid to the container or drum.
