Various examples are provided for containers. In one embodiment, a container includes an inner void extending along an axial length of the container. The inner void includes a closed end adjacent to a first end of the container and an open end at a second end of the container. The container also includes an outer void extending along the axial length of the container. The outer void encircles at least a portion of the inner void along the axial length of the container. The outer void includes a closed end encircling the inner void adjacent to the open end of the inner void and an open end at the first end of the container. An outer wall of the outer void includes a transition to a diameter of an opening at the open end of the outer void and that is adjacent to the closed end of the inner void. |
