Your can is made by the Aervoid Mfg. Co. in Chicago. Their web site is http://www.aervoid.com/ I bought a few replacement parts from them online last year for my 2 five gallon dispensers. You can get a new lid for yours.
Yes, I figured that was their name now. The name on the container is Vacuum Can Company. They want too much for a lid. I can make something else work.
