A pitcher for holding flexible bags filled with milk or other liquids. The pitcher comprises a substantially rigid housing having a bottom, sides and a generally open top forming a generally hollow interior capable of receiving therein a flexible bag filled with liquid. The housing is dimensioned so that at least a portion of the bag extends upwardly through the open top when the bag is received within the hollow interior. At least one bag clamping member is attached to the housing and is movable between an engaged position and a disengaged position. When it is in its disengaged position the clamping member is generally adjacent to the sides of the housing. When it is in its engaged position the clamping member extends upwardly from the open top of the housing and is releasably securable to a portion of a bag received within the hollow interior of the housing to assist in maintaining the bag in an upright configuration.
