Abstract
A child-resistant multi-step tear-access blister package having at least one product well containing a product. The product is accessed by tearing the blister package from a peripheral edge toward the product well. A step in addition to tearing is required to access the product, thereby elevating the cognitive skill necessary to access the product above those of a typical small child. In the disclosed exemplary embodiment, the additional step involves weakening a tear-resistant channel blocking a tear path from the peripheral edge of the package to the product well. More particularly, initial tearing of the package toward the product well is interfered with by the presence of the tear-resistant channel interrupting the tear path. The tear-resistant channel may be bent or snapped to permit tearing therethrough and to permit continued tearing of the blister package toward the product well to access the product.
