Abstract

Abstract A dispensing device formed of a cradle for receiving a brick pack. The cradle includes a pair of apertures located near the bottom and top of the cradle. The dispensing member has a pair of spikes at each end thereof which pass through the pair of apertures in the cradle and pierce the brick pack contained by the cradle. The spikes each have openings therein which communicate with the hollow interior of the dispenser to permit the flow of fluid therein. At the top end of the dispenser is a vent opening having a filter therein for permitting the ingress of air. At the bottom of the dispenser is an opening for permitting the egress of fluid from the brick pack and the dispenser. Preferably the dispenser has a graduated scale to indicate the level of fluid in the brick pack.
