Abstract: A closure device for a carton having a gable top. The device comprises a flanged cap including a pair of inner surfaces defining a longitudinal slot. The device further includes inclined side walls extending from the flanged cap and adapted to make a snug fit with the gable top. The device further includes front and rear walls contiguous with the inclined side walls and angled side walls adjacent the inclined side walls extending from the rear wall toward the front wall. The inclined side walls and angled side walls are spaced a distance apart to define a recess. The carton comprises a pair of vertical strips have an upper and lower edge, and inclined sidewalls extending outwardly and downwardly from the lower edge of the vertical strips. The strips have inner and outer surfaces. The inner surfaces of the strips are sealed together along their longitudinal length. The outer surfaces of the strips of the carton are disposed within the longitudinal slot in a confining relationship.

The carton comprises a pair of vertical strips have an upper and lower edge, and inclined sidewalls extending outwardly and downwardly from the lower edge of the vertical strips. The strips have inner and outer surfaces. The inner surfaces of the strips are sealed together along their longitudinal length, so that when one end of the strips are pried apart, a pouring spout is formed for dispensing contents from the carton.

Abstract: A device for protecting the contents of cartons with gable tops from odor, dust, dirt or other contaminants and from spillage after the carton is opened. The device is placed upon the carton and covers a portion of the top part of the carton. A longitudinal gap in the device encloses and presses together the top strips of the carton, which were pried apart to form a spout for dispensing the contents of the carton, thereby closing the carton.The present device possesses shortened inclined walls as well as end walls having a lower arcuate convex edge to facilitate a gripping by the fingers of a user.

Abstract: A device for protecting the contents of cartons with gable tops from odor, dust, dirt or other contaminants and from spillage after the carton is opened, is disclosed. The device is placed upon the carton and covers the top part of the carton. A longitudinal gap in the device encloses and presses together the top strips of the carton, which were pried apart to form a spout for dispensing the contents of the carton, thereby closing the carton.For larger cartons, the device incorporates a section for holding the carton with a handle for tilting the carton to dispense its contents. In one embodiment, the closure section of the device snaps onto the holding section to close the carton. In a second embodiment, the closure section is connected to the holding section by a hinge.
