PROCESS FOR CLOSING A CONTAINER IN METAL SHEET |
摘要 |
The container has a tubular body having a peripheral lateral wall provided with an upper end portion and a lower end portion defining an upper retention hook and a lower retention hook to which is double-seamed a lower end wall. An upper end wall is conformed to incorporate a peripheral upper skirt presenting an end edge defining an inverted U shaped upper closure hook to be seated onto the upper retention hook sandwiching an elastic sealing element therebetween. The upper closure hook and the upper retention hook and also a portion of the peripheral upper skirt and a confronting region of the upper end portion are deformed for seaming the upper closure hook onto the upper retention hook and to form, respectively, a retention rib and a retention groove which tightly fits the retention rib. |
