Abstract
A paperboard carton and plastic pour spout fitment construction for cartons adapted to carry powdered or granular material, particularly foodstuffs. A side wall of the carton is provided with a precut opening to receive the separate fitment. The periphery of the sides of the pour spout bottom wall must be broken from the surrounding fitment by the consumer upon initial use, to permit the spout to pivot for dispensing. The spout is thus held against accidental opening during shipping and handling prior to use, and further, such breaking is automatically tamper evident. The fitment is attached to a side wall of the carton by use of an adhesive or by a plurality of rivet stakes integral with the spout. The rivet stakes are received in complementary punctures bordering the precut opening. The use of plastic for the pour spout fitment insures against metal particles contaminating the contents of the carton.
