US Patent 7854325 Childproof package

A childproof package includes a package housing, two guide recesses, which are formed in an area of an inside surface of the package housing, and a sliding element for a package content. The sliding element has two projections on its top or bottom surface, which are guided in the guide recesses. Further, the childproof package has a spring element arranged between the package housing and the sliding element. The projections can be latched by the elastic force of the spring element in notches, which extend from the guide recesses and branch off from it, and can be released against the elastic force of the spring element so that the projections are returned to the guide recesses.
