ABSTRACT:
The present invention refers to a constructive arrangement applied to an opening device for packages of the carton type, containing a dry product, either powdered or granulated, such as powdered soap or the like. The constructive arrangement includes a transversely semiarticulated tongue which has perforated lines. The tongue is defined by a semicircular area disposed in one of the side faces of the package and by a rectangular area disposed in the upper face thereof. An articulated rectangular flap is positioned on the portion which is disposed in the upper face and also has perforated lines. To open the package, these perforated lines are broken and the semiarticulated tongue and the rectangular flap are moved so as to be juxtaposed in the vertical position in the upper face of the package. In operation, the semiarticulated tongue is folded so that its semicircular and rectangular parts will be joined together in the vertical position.
