Abstract
A cap arranged to interact with a spout. The cap includes a top section, a side wall section attached to the top section and a tamper element attached to the side wall section in a tearing interface. The tearing interface may be provided with a weakening line that is arranged to break when the cap is unscrewed such that the tamper element is separated from the side wall section. The cap further includes at least one resilient cutting element arranged to the side wall. The at least one resilient cutting element is arranged to cut off a membrane of the spout when the cap is unscrewed. The cap is arranged such that the weakening line is arranged to break before the membrane of the spout is cut off when the cap is being unscrewed from the spout.
