A container for storing phase-change ink includes a housing that is comprised primarily of a thermally insulating material and an inductive heater element positioned within the housing. A cam is actuated by the handle that allows the handle to be moved into a locked position for hands-free operation. The patterned second gate structure includes at least one of a first section extending in the first direction over the first section of the patterned first gate structure or a second section extending in the second direction over the second section of the patterned first gate structure. In other embodiments, a vial comprises a bag for regulating pressure within the vial as liquid is removed therefrom. A layer of wax or photo-sensitive organic material is then applied, and can be used as the temporary glue.
