1. A method of forming a container for containing a cold fluid, comprising;
obtaining a base container having an inner sidewall and a bottom secured to the inner sidewall, the inner sidewall extending at least partially around an interior that defines an interior volume of the container;
forming a plurality of annular bands on the inner sidewall of the base container; the forming the plurality of annular bands comprises applying a first layer of material to the inner sidewall and a second layer of material to the first layer of material;
obtaining an outer sleeve;
attaching the outer sleeve to the inner sidewall to form a sidewall construct of the container with insulating features defined between the inner sidewall and the outer sleeve, the attaching the outer sleeve comprises pressing the outer sleeve against the plurality of annular bands to adhesively secure the outer sleeve to the inner sidewall, the insulating features comprise a cavity between the inner sidewall and the outer sleeve, the plurality of annular bands, and a plurality of pockets in the cavity formed between adjacent annular bands, the insulating features are for maintaining a desired temperature of the cold fluid in the interior volume of the container.
