An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The second outer wall can include a second end configured to support the container on a surface. The second outer wall can include a dimple, and the dimple can include a circular base and an inner portion converging to an hole extending into the second outer wall. The hole can be sealed by a resin, and the circular base can be covered by disc formed of the material. Alternatively, a cap can cover the dimple, and a weld can connect the cap to the second outer wall. The container can also include a sealed vacuum cavity forming an insulated double-wall structure between the first inner wall and the second outer wall.
