A lid has an inverted U-shaped peripheral rim, which rim snaps over the upper edge of a container sidewall. There are three separate sealing zones between the lid and the container. First, the cover portion interior of the snap on rim has a plug fit interference relationship with the interior of the container. Second, the outer leg of the snap on rim has an interference relationship with an outwardly extending sidewall ridge near the upper edge of the container. Third, the outer leg of the snap on rim also has an inwardly facing ridge which snaps over the sidewall ridge and has an interference relationship with the outer surface of the container sidewall. A tear-off strip constitutes the lower portion of the outer leg of the snap on ridge and tears off below the inwardly facing ridge. The lower edge of this tear off strip abuts against a ledge which extends outward from the container sidewall thereby inhibiting tampering with the strip until initial opening is intended. A vertical weakening line adjacent a pull tab on the tear-off strip further inhibits tampering with the tear-off strip.
