A handle may be provided with a neck supporting part that mates with the neck of the bottle, a bottom supporting part that receives the bottom of a bottle and supports the bottom of the bottle, and a gripping part that connects the bottom supporting part and the neck supporting part. The neck supporting part may have a first engagement part and a second engagement part with which the neck may engage and disengage. The gripping part extends in a substantially vertical direction along the body of the bottle when the neck is engaged with the first engagement part and extends in a substantially slanted direction relative to the substantially vertical direction so as to draw apart from the bottle when the neck is engaged with the second engagement part.
