Abstract
A package for a product includes a base plate on which the product is disposed, and a bridge disposed on the base plate in overlying relationship to a first portion of the product. A lid is disposed in overlying relationship to a second portion of the product and is secured to the base plate by a sliding connection which guides the lid for limited sliding movement parallel to the base plate to expose the second portion of the product. The sliding connection constrains the lid against dislodgment from the base plate in a direction perpendicular to the base plate. An intermediate plate is disposed between the base plate and the lid and is arranged to prevent the sliding movement of the lid. The intermediate plate is formed of a tearable material, such as cardboard, wherein tearing of the intermediate plate releases the lid for the sliding movement.
