Abstract
Abstract An ornamental fish bowl closed on all sides and including a water pump with an aspirator for circulating the water and adding small air bubbles to it. The water is directed through an aspirator and a filter for removing suspended solids, then through a first screen to an annular space where the fish are confined. A second screen permits water to be drawn from the annular space and directed to the entrance pipe of the water pump.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
An enclosed water container for use as a fish bowl and including water circulating means comprising: a liquid retaining base for supporting all the container components; an annular compartment filled with water and supported by the base for accommodating fish; a cylindrical central enclosure connected to the annular comparTment for housing parts of the circulating means; a water pump powered by an electric motor in said enclosure; a first aspirator connected to the pump for reducing the pressure in the annular compartment; a second aspirator connected to the first for adding bubbles of air from the atmosphere to the water; a water filter coupled to said aspirators for removing solids from the circulating water; and conduit connecting means between the components in said central enclosure for directing the circulating water through said components and the annular compartment.

Claim 3
Dependent Claim
21 words
A container according to claim 1 wherein said annular compartment includes a cover plate which is made of transparent plastic material.
Claim 4
Dependent Claim
27 words
A container according to claim 2 wherein said cover plate is generally flat and is secured to the annular compartment by means of resilient water tight seals.
Claim 5
Dependent Claim
40 words
A container according to claim 1 wherein the first aspirator comprises a nozzle positioned adjacent to a constricted conduit, the annular space surrounding said nozzle being connected to the top portion of the annular compartment for reducing the pressure therein.
Claim 6
Dependent Claim
58 words
A container according to claim 1 wherein the second aspirator is mounted above the first and in axial alignment therewith, the second aspirator comprising a nozzle positioned adjacent to a constricted conduit, the annular space surrounding said nozzle being connected to the outside air for drawing air into the second aspirator and mixing air bubbles with the water.
Claim 7
Dependent Claim
22 words
A container according to claim 5 wherein said second aspirator is connected by a conduit to an opening in the cover plate.
Claim 8
Dependent Claim
31 words
A container according to claim 1 wherein said water filter includes a removable receptacle positioned around a casing connected to said second aspirator, said receptacle including a quantity of small particles.
Claim 9
Dependent Claim
48 words
A container according to claim 1 wherein a hollow cylindrical support is positioned around the central enclosure, thereby forming a cylindrical space in axial alignment with said first and second nozzles for forming conduits therebetween to direct the flow of water into and out of the annular compartment.
Claim 10
Dependent Claim
38 words
