Tamper-evident lid that cannot be removed

摘要

A tamper resistant lid (10) for a container (1). The lid (10) exhibits a centre axis (X) and comprises an outer and an inner member (20, 40). The outer and inner members (20, 40) each comprise an outer and inner surface (26, 27, 46, 47) wherein at least a part of the outer surface (46) of the inner member (40) is substantially adjacent at least a part of the inner surface (27) of the outer member (20). The inner member (40) comprises connection means (48) enabling a connection to the container (1) by means of rotating the outer member (20) in a first direction. The lid (10) comprises at least one stop member (51, 52, 53, 60) preventing the inner member (40) from rotation with respect to the outer member (20). The at least one stop member (51, 52, 53, 60) is adapted to be controllably disabled with a designated force after the inner member (40) has been connected to the container (1), so that the outer member (20) can be freely rotated with respect to the inner member (40) to thereby prevent removal of the lid from the container (1).
