Abstract: The invention relates to a closure cap for a substantially cylindrical vessel, with a lateral surface, a closed end and an open end, and with a tear-open strip having a grip tab for opening the closure cap. In order to produce closure caps which are designed such that they can be applied by machine to substantially cylindrical vessels, it is proposed within the context of the invention that the lateral surface is substantially cylindrical, at least in the area of the open end, and that the closure cap is of stackable design and has means for stacking at least two closure caps with defined spacing. The invention is based on the finding that, for cost reasons, it is useful if also closure caps for substantially cylindrical vessels can be stacked, i.e. pushed onto one another, during transport as they then take up less space.

Abstract: The present invention relates to a capsule for a substantially cylindrical vessel with a shell surface, an upper open end, and a lower closed end, wherein the shell surface, at least in the area of the open end, is of substantially cylindrical design. In order to protect substantially cylindrical vessels against breakage in cost-effective manner, it is suggested in the scope of the invention that the shell surface above the closed end comprises at least one means for forming a free space, which is a crimp, directed at least partially inwards on the shell surface. Here, the capsule is configured in such a way, that it can be fitted onto the bottom-side end of the substantially cylindrical vessel. The tolerance limits of the substantially cylindrical vessel are thereby compensated.
