    Abstract: A milk container has a support and pouring handle adapted to detachably connect the container to adjacent and similar milk containers. The container is a conventional gable top container and includes a handle assembly attached to the top portion of the gable top such that one end of the handle assembly extends outwardly beyond the side walls and gable top of the container. The handle portion can be integrally formed as part of the container blank or can be separately formed and attached to the top portion of a conventional gable top container by adhesive and/or staples. The handle is positioned on the container at the end of the gable top opposite from the end of the gable top which includes the pouring spout for the container. One face of the handle is covered with adhesive such that when adjacent similar containers are positioned so that these adhesive covered faces come into contact with one another, the two handles will become attached.
