A two-piece tamper-evident band assembly for use with a container and closure combination, where the container has a peripheral collar and the closure has a skirt, is shown. The tamper-evident band assembly includes a breakaway band frangibly connected to a staying ring. The staying ring has decreased flexibility where it connects to the container and closure combination, which prevents the assembly from deforming in a manner that will cause the assembly to fail to indicate that the container has been opened. The tamper-evident band assembly also indicates whether the container has been compromised without requiring modification of the container or the closure and can be applied to existing container and closure combinations that lack a tamper-evident system, allowing the assembly to be used with a variety of container and closure combinations.

An overmolded valve is provided for use in a container having a throat. The valve is inserted into the throat of the container and prevents liquid from flowing from the container during shipment or storage. When the container is inverted for use with a dosing and/or dispensing apparatus, the valve remains closed until it is opened by an upward force to permit liquid to flow from the container, by gravity, to the dosing and/or dispensing apparatus. The valve closes when the upward force is removed. A pair of plastic semi-helical springs urge the valve to the closed position.

The invention relates to a container closure (10) comprising a base portion (16) which extends about a reference axis (100) of the container closure (10), a cap portion (18) which in a closed positioned covers a drinking hole (30) in the container closure (10) and in an open position leaves said drinking hole in the container closure (10) uncovered, and a tamper-evident ring (14) which is separate from the cap portion (18) and the base portion (16) and is interlockingly connected to the cap portion (18) and connected to the base portion (14) in a hooked manner. The tamper-evident ring (18) has an annular bead (56) that is not radially covered by the base portion (16) and extends in an annular groove (54) of an outer wall (34) of the cap portion (18), which wall faces radially outward.
