Abstract: A dispenser for powdered, granular, pellet, briquette or tablet-like material is provided. The dispenser includes a dispenser head through which the material dissolved in water can be dispensed. A spray device is provided at the head to spray water onto the material provided in the dispenser head. A suspension device is provided to suspend a bag containing the material above the dispenser head. The bag in its suspended orientation has a fastener along the bottom end which closes the bottom end of the bag. The fastener is not, however, releasable until after the bag is mounted in the dispenser. Then the fastener is releasable to allow the contents thereof to fall by gravity onto the dispenser head. The dispenser provides a system, which normally avoids contact of the toxic contents of the bag with the user. At the same time, the only waste is in the form of a bag which may be made of recyclable plastic, hence minimizing waste associated with the system.

Abstract: A close for allowing the emptying of the contents of a container comprises: a hollow closure member (1) for a container, the closure member having an outlet (2) for the contents; a rotatable plug (3) mounted within the closure member, the plug having a first through-passage (4) for the contents with an inlet (32) and an outlet (34), the plug being rotatable between a first closed position in which the inlet (32) of the through-passage is out of register with the closure member outlet (2) and a second position in which the inlet is in register with the closure member outlet to permit the contents to pass into the passageway; a connector (5) for transfer of the contents out of the container, the connector having means (7) to engage the exposed portion of the plug, and the connector (5) when engaged with the plug (3) can be turned to rotate the plug to the open position, or to the closed position.
