The data width corrector of the invention adjusts the data width appropriately even for data in which cross points have already deviated at the time of input. The crosslinked beta-cyclodextrin is prepared by crosslinking beta-cyclodextrin in the presence of a crosslinking agent. In one embodiment, the swellable elastomeric material comprises a base elastomer and at least one additive selected to modify the surface energy. The loop heat pipe has a small amount of operation fluid inside, the inside of the loop heat pipe being under vacuum. The outlet valve portion includes a resilient outlet flange that is positioned within the outlet channel for selectively permitting a first flow therethrough and out of the drink container.
