Patent ID: 10618711

Abstract:
A tamper-evident closure (101) comprises a first portion (105, 106) and a second portion (102, 104) comprising a window (103) through which a view of the first portion (105, 106) is visible. The second portion (102, 104) is rotated relative to the first portion (105, 106) upon first opening of the tamper-evident closure (101), from a first position in which the first and second portions (105, 106; 102, 104) are in a first relative relation and a first view of the first portion (105, 106) is visible through the window (103), to a second position in which the first and second portions (105, 106; 102, 104) are in a second relative relation and a second, different view of the first portion (105, 106) is visible through the window (103). A locking mechanism irreversibly locks the first and second portions (105, 106; 102, 104) in the second relative relation.
