»schraubverschlüsse

I used Google to help me understand the "öffner fur schraubverschlüsse" that I picked up today from the not-quite-a-store, not-quite-an-art-gallery Kiosk. I know that the device, a Monopol Hermetus, can open a beer bottle with a patent top; and, with its rubber gasket, can keep an open bottle, patent or cork-topped, sealed. The schraubverschlüsse opener works on screw tops, which may sometimes act recalcitrant.
