A carton particularly constructed for receiving a container having a spout wherein the top closure flaps of the carton have openings means for permitting the projection of the spout for the purpose of filling the container or dispensing the contents thereof. The opening means includes deflectable flaps in inner flaps aligned with a through opening in the outer flaps with the deflectable flaps serving to protect a dust cover carried by the closure against direct engagement by the container spout. The deflectable flaps are bendable through the through opening in the outer flaps and serve to define a lock to hold the spout in its extended or projected position. The deflectable flaps have intermediate fold lines facilitating the folding thereof to release the spout.
In a carton for a container having a spout, a closure flap arrangement, said closure flap arrangement comprising first and second inner flaps and first and second outer flaps, said outer flaps being bonded to said inner flaps, said inner flaps having free edges positionable in opposed adjacent relation, opening defining means formed in said inner flaps and opening through said free edges for alignment with each other when said free edges are in said opposed relation to define a single opening, said opening defining means being offset to one side of centers of said free edges, one of said outer flaps having a through opening formed therethrough remote from edges thereof and alignable with said single opening, each of said opening defining means including a deflectable flap formed from the respective inner flap and permanently hingedly connected to said respective inner flap along a hinge line generally parallel to and remote from said respective inner flap free edge.
