German to English Tech/Engineering Manufacturing soft drink cans

This term appears twice in a description as to why the new can geometry is better than the old. In particular, that the new offers greater pressure stability while using thinner sheets of metal.
My problem is with the problem they've solved:

die Erfindung vermeidet das im Stand der Technik noch auftretende *Umspringen* des Zentralbodenabschnitts

Der Bodenabschnitt ist dadurch mit hoher Zuverlässigkeit gegen jede *Umspringtendenz* gesichert.

'umspringen' means to jump around, and I can't see jumping aluminium cans as a major problem. However, cans that burst due to internal pressure would seem to be a major problem.
"Sprengen" would work here, if this were just a typo, but I can't find "umsprengen" anywhere.

If 'Umspringen/Umspringtendenz' isn't a typo, then it might refer to a situation in which the base section, which has a internally-projecting dome shape, explosively reverses this projection, like an umbrella in the wind, which could indeed lead to jumping cans. Which may indeed be a serious problem.

Any ideas on either possibility?
