Abstract
Tamper-resistance is provided in spice container closures and containers through use of tamper-evident and/or tamper-resistant elements. A tamper evident closure includes a base, a cover, and a tamper strip, with the tamper strip being joined to the base and cover by a first hinge connecting the tamper strip to the base and a second hinge connecting the tamper strip to the cover. At least one dispensing port in the base is selectively coverable by a flap of the cover. The tamper strip is adapted to be manually torn away and fully released from the cover and base. The flap is hinged to the cover by a third hinge. In addition, or alternatively, a snap lock connection is formed between a container closure and the container.
