Hershey's Kisses are chocolates first produced by the Hershey Company in 1907. The bite-sized pieces of chocolate have a distinctive conical shape, sometimes described as flat-bottomed teardrops. Hershey's Kisses chocolates are wrapped in squares of lightweight aluminum foil. A narrow strip of paper, called a plume, protrudes from the top of each Hershey's Kiss wrapper. Originally designed as a flag for the "Hershey's" brand, the printed paper plumes were added to the Kisses product wrapper in 1921 to distinguish the Hershey's Kiss from its competitors who were offering similar products.[1]
History
When first manufactured in 1907, Hershey's Kisses were wrapped by hand. In 1921, a machine was used so the Kisses would be wrapped automatically. This machinery also added the paper plume or paper strip flag to the aluminum foil wrapper to identify Hershey's Kisses, replacing the original small square of printed tissue that was inside the foil wrapper.[2]
In 1924, Milton S. Hershey received a registered design trademark (Reg. 0186828) for "foil wrapped conical configuration with plume" which included the paper plume sticking out from the top of the aluminum foil wrapper.[3]
