A tamper-evident push-in easy-opening closure in a sheet metal container member comprising an opening (1) in the container member (2), an integral closure member (3) for the opening in overlapping and underlying relationship with the free edge portion (7) defining the opening (1), the free edge portion (6) of the closure member (3) being formed with spaced latch members (8, 9; 8', 9') dimensioned to engage the free edge portion (7) around the opening (1) to increase the push-in force required to open the closure member (3) to a level which ensures that sealant (S) for sealing the closure member (3) in the opening (1) is fully broken whenever the closure member is opened, said closure member (3) being formed with a central upstanding portion (5) dimensioned to be in close proximity to said free edge portion (7) and being substantially perpendicular to a rim (6) extending from said upstanding portion (5), to thereby restrict the entry of foreign objects through said closure without visibly opening said closure. |
