[1][2][3] Leo Hulseman, a former employee of the Dixie Co. in the 1930s, created the "Solo Cup", a paper cone he made at his home and sold to bottled-water companies.

On March 1, 2004, Solo acquired Sweetheart Cup Company for $917.2 million, in part with public debt.

It became the largest consumer packaging company in the world and was sold several times before being acquired by Solo Cup.

[7] In 2005, the Museum of Modern Art in New York City added a Solo Cup Traveler's Lid to its permanent collection.

His wife, Dorothy Donahoe Hulseman (1900–1988), better known by her stage name Dora Hall, was a singer whose records were given away free of charge through Solo promotions.

[17] Premore produced children's TV shows including Tony the Pony (like the later Barney & Friends) and The Cliffwood Avenue Kids (like Our Gang).

[7] Solo Cup customers include Starbucks, Dairy Queen, Così, Walmart, Whole Foods Market, Einstein Bros. Bagels, Publix, and Tim Hortons, as well as many universities.

Specifically, indentations at approximately 1, 5, and 12 ounce levels are believed to denote recommended pours for hard liquor, wine, and beer, respectively.

However, Solo refutes this claim, stating that the markings are open to interpretation and noting that many of their cup designs do not have these specific indented rings.
