A patent issued today to a team of French inventors for a Champagne gift box that expands into an ice bucket.
The patent (8,127,927) explains that the combined box and bucket is folded from a single sheet of cardboard and lined with plastic. After the box top (10,11) is pulled off, the sides (5) of the box fold outward to form a bucket shape, and ice can be added to chill of the bottle.
Sharing the likely fate of the patented champagne box, the patent itself has been re-gifted several times within the same family. It belonged first to Veuve Clicquot, then to Champagne Krug, and finally to Moët Hennessy Champagne et Services (MHCS), all members of the LVMH family of luxury brands. (I think I know what Louis Vuitton is getting for Christmas!)
