About Us

Thornton Plastics Company was founded in 1948 by Wayne Thornton. The first product line consisted of Christmas bells, screwdriver handles, plastic spoons and plastic tumblers. In 1955 a new product line was launched. It consisted of clear and amber colored plastic vials with snap on caps. The vials were sold mainly to pharmacies and hobby stores.

In 1960 the company was incorporated. With a steady increase of vial sales, the other product lines were fazed out. The vial product line grew to 10 different sizes of vials, both clear and amber colored, ranging from a 3.5 dram to a 50 dram vial (.125 ounces in a dram). In 1997, the amber vials were dropped from production with focus on the clear transparent vials.

In 1997, Wayne Thornton, founder of Thornton Plastics passed away. The company was managed by his daughter, Renee Thornton, for many years. 

In 2005, Briton C. McConkie, Wayne Thornton's grandson, became the President. The company has expanded their snap-cap vial line to 14 sizes and recently expanded into hinged lid containers.
