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.

A pour spout and carton construction including a paperboard carton adapted to contain powdered or granular material, said carton having at least one flat wall portion, said flat portion having a dispensing opening therein, a unitary plastic pour spout fitment, said fitment including a generally U-shaped flat wall attached to said carton flat wall portion, a pour spout having a bottom wall and two parallel, curved side walls both extending in the same direction from and perpendicular to said bottom spout wall and toward the carton interior, said bottom wall integrally hinged at one end thereof to the middle portion of said U-shaped flat wall and whose side edges are frangibly secured to the legs of said U-shaped wall by frangible connections, whereby the pour spout bottom wall is normally parallel to said carton flat portion and coplanar with the legs of said U-shaped fitment, whereby the pour spout is openable to permit dispensing by breaking the bottom wall thereof from its frangible connections to the legs of the U-shaped wall, and whereby such breaking is evidence of opening of the pour spout, and means for providing an interference, snap-fit at the edges of the pour spout bottom wall, said means comprising stretched portions of the plastic of the frangible connections upon breaking the frangible connections to thereby enable the spout to be reclosed to substantially its initial position.
