(57) There is disclosed a covered container comprising a container body (14) and a lid
(12). The container body (14) has a bottom (16) and four sidewalls (18,20, 22,24),
the upper portion of each sidewall (18,20,22, 24) terminating in a sealing rim (28)
having an outer sealing corner (32), an inner sealing corner (30) and a shelf (26)
below the inner sealing corner (30). The container has a flexible lid (12) having
a circumferential sealing ridge (40) comprising a downwardly sloping outer ridge (44)
and a downwardly sloping inner ridge wall (46) and a circumferential trough (48) adjacent
the sealing ridge (40). When the container is closed, a primary container seal is
formed between one sealing corner of each wall and its corresponding ridge wall in
the lid. The circumferential trough (48) and shelf (26) forms a secondary seal within
the container located below the primary seal and is particularly effective in inhibiting
moisture that condenses on the lid from migrating to the primary seal.
