The envelope is receivable between the at least one cover portion and the main body of the shipping container and at least one of the first and second flap portions is affixable to an exterior surface of the container.

Abstract: The present invention relates to a pocket knife having a rotation type can opener for opening a can. The rotation type can opener has a crank, a shaft, a gear and a cutting blade; the upper rim of the can is put to be infixed between the cutting blade and the gear, with the top end of the can holding the cutting blade; the crank is rotated to drive the rotation of the shaft, the rotated shaft further drives the rotation of the gear, and the rotated gear engages the upper rim of the can and drives the rotation of the can; the top end of the rotated can produces a pressure against the cutting blade so that the cutting blade first penetrates and then rotationally cuts apart the top end of the can.
