Container with insulating features

A sidewall construct for forming a fluid container for containing a cold fluid, the sidewall construct comprising:

• an inner sidewall extending at least partially around an interior of the container;
• an outer sleeve attached to the inner sidewall;
• a cavity defined between the inner sidewall and the outer sleeve;
• and
• insulating features comprising the cavity and a plurality of annular bands, each annular band of the plurality of annular bands comprises a spacer that extends in the cavity from the inner sidewall to the outer sleeve, the spacer comprises at least a first layer of material and a second layer of material, and
• adjacent bands define a respective pocket of a plurality of pockets in the cavity for maintaining a desired temperature of the cold fluid.

A method of forming a container for containing a cold fluid, comprising;

• obtaining an inner sidewall and an outer sleeve;
• attaching the outer sleeve to the inner sidewall to form a sidewall construct with a cavity defined between the inner sidewall and the outer sleeve, the attaching comprises forming insulating features in the sidewall construct, the insulating features comprise the cavity and a plurality of annular bands, each annular band of the plurality of annular bands comprises a spacer that extends in the cavity from the inner sidewall to the outer sleeve, the spacer comprises at least a first layer of material and a second layer of material, adjacent bands define a respective pocket of a plurality of pockets in the cavity for maintaining a desired temperature of the cold fluid;
• forming an interior of the container by positioning the sidewall construct so that the inner sidewall extends at least partially around the interior;
• and
• positioning a closed bottom relative to the sidewall construct.
