Hulseman spent nearly 60 years with the foodservice packaging company started in 1936 by his father, Leo.
The company was based in Lake Forest, Illinois, and made disposable food and drink containers from paper, plastic and recycled materials.
The red plastic Solo Cup was introduced in the 1970s and has become a fixture at family gatherings and picnics.
Dart Container Corp. of Mason, Michigan, bought Solo Cup in 2012.
