Monster energy drink from Hansen Natural Corp. has been introduced to the U.S. with a reclosable top.

Monster Import comes in 550-milliliter aluminum cans, filled in Holland and shipped to the United States. The top is a resealable end supplied by Ball Corp. The flat plastic disk rotates to open or seal off the can’s aperture.

Unlike other devices for resealing metal cans, the disk, trade-named Ball Resealable End, allows cans to be stacked. Cans featuring the Ball Resealable End were introduced last year in Europe, and attracted attention from Monster execs at a Spanish trade show.
