Disposable container and lid matching system and methods

A method of putting a lid on a disposable container;

• the method comprising:
• (a) providing a container having a bottom and a surrounding wall extending from the bottom;
• (i) the bottom and wall defining a container volume;
• (ii) the wall having an end remote from the bottom;
• the end defining a lid-receiving rim;
• (iii) the wall having at least a first wall section and a second opposing wall section;
• (A) a first graphic arbitrary symbol defined on the first wall section;
• the first graphic arbitrary symbol having a purpose exclusively for use in a matching system and being otherwise uninformative;
• (B) a second graphic arbitrary symbol defined on the second wall section;
• the second graphic symbol being the same as the first graphic symbol;
• the second graphic arbitrary symbol having a purpose exclusively for use in a matching system and being otherwise uninformative;
• (b) viewing the container to see at least one of the first and second graphic symbols;
• (c) locating a lid sized to fit the rim of the container by looking for a lid having a third graphic arbitrary symbol on the lid;
• the third graphic symbol being the same as the first and second graphic symbols;
• the third graphic arbitrary symbol having a purpose exclusively for use in a matching system and being otherwise uninformative;
• and
• (d) operably placing the lid on the rim of the container to cover the container volume.

A disposable container and lid arrangement comprising:

• (a) a container having a bottom and a surrounding wall extending from the bottom;
• (i) the bottom and wall defining a container volume;
• (ii) the wall having an end remote from the bottom;
• the end defining a lid-receiving rim;
• (iii) the wall having at least a first wall section and a second opposing wall section;
• (A) a first graphic arbitrary symbol defined on the first wall section;
• the first graphic arbitrary symbol having a purpose exclusively for use in a matching system and being otherwise uninformative;
• (B) a second graphic arbitrary symbol defined on the second wall section;
• the second graphic symbol being the same as the first graphic symbol;
• the second graphic arbitrary symbol having a purpose exclusively for use in a matching system and being otherwise uninformative;
• (1) a straight line through the container volume between the first graphic symbol and second graphic symbol is non-perpendicular to the first wall section and the second wall section;
• and
• (b) a lid sized to releasably fit on the rim and provide a cover to the container volume;
• the lid having a body extending over the container volume when the lid is operably fit on the rim;
• (i) a third graphic arbitrary symbol defined on the body of the lid;
• the third graphic symbol being the same as the first and second graphic symbols;
• the third graphic arbitrary symbol having a purpose exclusively for use in a matching system and being otherwise uninformative;
• (ii) the body of the lid has a center, and the third graphic symbol is off-center on the body of the lid.
