Abstract: A tamper-evident label suitable for placement onto a container and cap assembly. The label may be characterized as a planar sheet having a tear strip that divides upper and lower panels. The lower panel of the label attaches to the container, while the upper panel, defined by at least one tab, and preferably two tabs, is attached to the cap. To open the container and cap assembly, the tear strip is pulled across the label to separate the two panels of the label. Thereafter, the cap may be removed from the container to reveal the contents of the container.
