Tupperware tumblers from the My parents still have these, with the snap on "pre-sippy cup" lids. I remember taking them on car rides with a pump-Thermos of water - each family member had a "color" for the trip.
Planters mainly a peanut company, came out with cheese balls in a canister unlike most that came in a bag. These set off for more companies to produce cheese balls. Planters is still a large company today.
