DUAL TAMPER EVIDENT CLOSURE

摘要

A dual tamper evident closure (1) for sealing the neck portion of a container (3). The closure (1) which is preferably made of one single piece of plastic material, has a body (15) with a skirt (17) sized and shaped to fit onto and be screwed or otherwise detachably fixed to the neck portion (5). The body (15) also has a top surface (25) with an opening (27) in registry with the outlet of the neck portion. The closure also has a cap (29) that is connected to the closure body (15) by a hinge (35) and is sized and shaped to cover the opening (27) of the body (15) and thus to close the outlet of the neck portion when folded down in a closed position. A tamper evident band (37) in the form of a ring is connected by frangible bridges (39) to the lower edge of the skirt (17) of the body (15). This band (37) is provided with hooks (41) designed to cooperate with an annular bead projecting from the neck portion in order to rigidly retain the body onto the neck portion. A tear tab (43) integrally projects from the peripheral edge of the closure cap in a position that is opposite to the hinge (35). This tear tab (43) has an upper end that is connected by a frangible bridge (45) to the peripheral edge of the closure cap (29), and a lower end (47) that is rigidly connected to the tamper evident band (37). In use, the tear tab (43) as long as it remains connected to the closure cap (29), warrants that the closure cap (29) has not been lifted up and thus the container (3) has not been opened.
