Abstract

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.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 155 words
A container having a hydration compartment adapted to receive therein a hydrating liquid and a material to be dissolved or dispersed thereinto, the compartment having sidewalls and endwalls and a floor from which an array of finger-like members project vertically upwardly into the compartment, the fingers being spaced from the sidewalls and endwalls with the tips of predetermined ones of the finger-like members being above the tips of others of the members within the compartment, the members being arranged with respect to each other to define a material receiving recess and being relatively spaced apart to define recirculating gaps therebetween such that, in use, the material to be dissolved by the application of ultrasonic energy from a source introduced into the compartment is confined within a relatively high energy zone defined by the recess and hydrating fluid is recirculated through and out of the relatively high energy zone through the gaps between the finger-like members.
Claim 2
Dependent Claim 155 words
A container having a hydration compartment adapted to receive therein a hydrating liquid and a material to be dissolved or dispersed thereinto, the compartment having sidewalls and endwalls and a floor from which an array of finger-like members project vertically upwardly into the compartment, the fingers being spaced from the sidewalls and endwalls with the tips of predetermined ones of the finger-like members being above the tips of others of the members within the compartment, the members being arranged with respect to each other to define a material receiving recess and being relatively spaced apart to define recirculating gaps therebetween such that, in use, the material to be dissolved by the application of ultrasonic energy from a source introduced into the compartment is confined within a relatively high energy zone defined by the recess and hydrating fluid is recirculated through and out of the relatively high energy zone through the gaps between the finger-like members.
Claim 3
Dependent Claim 29 words
The container of claim 1 further comprising planar members having side surfaces extending substantially perpendicularly of the floor, the planar members being oriented substantially on diagonals of the compartment.
