  • Patent number: 4720374
    Abstract: A container for the dissolution of a tablet of material is characterized by a plurality of projections mounted within the container. The projections cooperate to define a tablet-receiving recess adapted to confine a tablet inwardly therewithin in a relatively high energy zone during sonication of the tablet. Gaps between the projections define recirculating liquid channels whereby hydrating liquid passing through the tablet-receiving recess may be recirculated to other regions of the compartment.
