Abstract

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.
