It is known as the standard longneck bottle or industry standard bottle (ISB). The ISB longnecks have a uniform capacity, height, weight and diameter and can be reused on average 16 times. The long neck offers a long cushion of air to absorb the pressure of carbonation to reduce the risk of exploding. The longneck also provides a handle for drinking directly from the bottle without transferring body heat to the beer from one's hand.

A longneck is a type of beer bottle with a long neck.
