ABSTRACT:
The invention relates to a closing arrangements on cans and similar containers of the type which has at least one plane end wall of sheet metal with a hole punched out in the end wall. The cut surface of the said punched-out hole may be sealed effectively by a closing arrangement which is designed as a tubular plastic body with flanges projecting from the plastic body. The flanges embrace the edge zone of the hole when the closing arrangement is pressed into the hole, at the same time as the said cut edge of the end wall is pressed so as to form a seal against, or "is embedded in," the outside of the tubular plastic body.
