- the opening tab or beverage can closure member 10 has an upwardly curved surface and a centrally located downwardly curved surface 128 (this surface may also be located off center); the opening tab or the beverage can closure element is therefore wavy.
- the lock in this embodiment is also that the opening tab or beverage can closure element is pressed down, but it works here so that the waveform when turned down, turns over, ie, the upwardly curved surface curves downwardly and the downwardly centered surface 128 disposed in the middle curves upward, as seen in FIG.
- the reopening can be achieved here by pressing on the upwardly curved surface 128 (FIG. 57).
- FIGS. 58 to 59 show a variant with respect to the embodiment of FIGS. 54 to 57, wherein one or more gripping noses or a completely or only partially circumferential edge surround the edge of the removal opening when pushed in.
- the one or more gripping lugs or the edge which extends completely or only partially and encompasses the circumference is designated by the reference numeral 163.
- This locking is a kind of snapping, whereby possibly also a clamping action can occur.
- Figures 60 and 61, and 62 and 63 show locking similar to Figures 58 and 59.
- Figures 60 and 61 show an upwardly curved surface which completely turns over upon locking.
- Figures 62 and 63 show that the upwardly curved surface partially includes a horizontal surface 1210 (the horizontal surface may be arbitrarily large or small), whereby in the locked position, the opening tab or beverage can closure member extends less far down.
- FIG. 64 shows further variants with different nose shapes compared to the nose shapes shown in FIGS. 33 to 53.
- FIGS. 65 to 71 show that different shapes of discharge openings can be combined with different shapes of the curved surface of the opening tab or of the beverage can closure element.
