Jar assembly

A method of manufacturing a two-piece lid for a jar assembly, the method comprising:

• forming a metal outer cap comprising a first sidewall and a cap top that together define a lid cavity;
• forming a metal inner cap that is substantially cylindrical, wherein the inner cap comprises a second sidewall and a threading element provided about the second sidewall;
• bonding the metal inner cap within the lid cavity of the metal outer cap, such that the threading element is adjacent to the first sidewall, and such that the metal inner cap is fixed relative to the metal outer cap to inhibit relative movement between the metal inner cap and the metal outer cap;
• and
• precoating a metal material from which the metal outer cap is formed by pre-anodizing the metal material or electroplating the metal material.

A method of manufacturing a jar assembly, the method comprising:

• forming a two-piece lid by bonding a metal inner cap to a metal outer cap while the metal inner cap is nested within a lid cavity defined by the metal outer cap, wherein the metal inner cap comprises a sidewall provided with a threading element such that the metal inner cap is fixed relative to the metal outer cap to inhibit relative movement between the metal inner cap and the metal outer cap;
• and
• forming a base that defines another cavity of the jar assembly, wherein the base comprises an outer threading element provided about an exterior surface of the base, and wherein the inner threading element is mateable with the outer threading element;
• wherein the bonding comprises adhesive bonding or welded bonding, and
• wherein the metal outer cap and the metal inner cap are formed from a metal material, and the method further comprises precoating the metal material prior to forming the metal outer cap or the metal inner cap.

• and
• removably installing an inner cup within the another cavity of the jar.
