Abstract
A child-resistant package includes a nonrupturable layer, a rupturable layer attached to the nonrupturable layer, and a blister sheet attached to the rupturable layer. The blister sheet includes at least one article-receiving pocket which is covered by a portion of the rupturable layer. A portion of the nonrupturable layer is not attached to the rupturable layer to form a pull tab which extends in a first direction which does not extend toward the pocket. An article in the pocket can be accessed only by pulling the tab in the first direction and then pulling the tab in a second direction which extends toward the pocket to expose the portion of the rupturable layer which covers the pocket. The article can then be pushed through the rupturable layer.
