ABSTRACT This invention relates to a skip or loading flask which has a body defining a storage chamber and a sloping bottom. A discharge opening is defined in the body adjacent to the sloping bottom, and a door for closing the discharge opening is openable to allow material to be discharged from the chamber. The body includes at least one pair of opposed walls arranged so that the storage chamber widens downwardly within the body as a wear-reducing factor. The door may be operable by at least one door-operating mechanism such as over-centre mechanisms, arranged for normally holding the door closed. For example, over-centre mechanisms may at least partly extend alongside the opposite sides of the body and, in a skip, may be operable by movement of a follower along a cam track to open the door, more complex locking mechanisms thus being avoided. The door can be pivotable about an axis for closing the discharge opening, and the sloping bottom and the door may then have supporting surfaces meeting at a junction substantially extending along said axis to restrict passage of material between the surfaces. A loading flask of the invention can be used with a feeder chute located to guide material discharged over the door and having a feeder surface at a steeper slope than the door when the door is in its fully open position.
