Abstract
A bag is provided with a collapsible spout for directing the flow of the contents of the bag during pouring. The collapsible spout can include folds so that the collapsible spout can transition from a substantially flat undeployed configuration to a deployed spout-shaped configuration. The collapsible spout can also include a fastening mechanism so that an opening in the bag can be closed or resealed. A bag can also include a resealable opening for directing the flow of the contents of the bag during pouring. The resealable opening can include a panel with a fastening mechanism so that an opening in the bag can be closed or resealed.
