ABSTRACT:
A paperboard carton for dry, flowable products such as laundry soap, powdered milk and the like is characterized by a pour spout positioned within an opening in the side of the carton which spout is capable of containing a predetermined amount of material, sealing the opening in the carton after the spout container is filled, sealing the opening in the carton when not in use, and allowing a free flow of material when in a certain position. The spout is also composed of paperboard or similar material and is inexpensively assembled and shipped with the main carton. A special wiping and sealing mechanism ensures absence of leakage in the area of the spout. The spout is provided with an automatic locking arrangement which enables it to be shipped within the filled carton in a flat condition so as to create no voids within the carton and then be set up into a permanent pour spout by the user in one simple operation.
