Abstract
Abstract A package construction which is particularly suitable for pills and tablets is formed from a flexible plastic container having a recess which holds the product and a composite lid which forms an air-tight package. The lid includes a rupturable layer, and a protective layer which is joined to the rupturable layer by a peelable adhesive. Access to the package contents is achieved by stripping the protective layer followed by pushing the product through the rupturable layer.
