Abstract
Abstract A compound vessel is provided which has many decorative and functional applications. The compound vessel is formed of a transparent material and has a spheroidal main body. The main body is comprised of spheroidal inner and outer walls with an annular space defined therebetween. The annular space constitutes an outer vessel of the compound vessel and the space contained by the inner wall constitutes an inner vessel of the compound vessel. The outer and inner walls join at one extremity of the spheroidal main body of the compound vessel to close the outer vessel and form the periphery of a generally circular mouth opening into the inner vessel, the inner vessel being otherwise closed. The outer wall terminates at an opposite extremity of the spheroidal main body of the compound vessel to form the periphery of a generally circular mouth opening into the outer vessel, the outer vessel being otherwise closed.

Claim 1
Independent Claim
221 words
A compound vessel formed of a transparent clear material and having a spheroidal main body, comprising spheroidal inner and outer walls with an annular space defined therebetween, the annular space constituting an outer vessel of the compound vessel and the interior space contained by the inner wall constituting an inner vessel of the compound vessel, the outer and inner walls joining at one extremity of the spheroidal main body of the compound vessel to close the outer vessel and form the periphery of a generally circular mouth opening into the inner vessel, said inner vessel being otherwise closed, the outer wall terminating at an opposite extremity of the spheroidal main body of the compound vessel to form the periphery of a generally circular mouth opening into the interior of the outer vessel, said outer vessel being otherwise closed said outer vessel being filled with a transparent clear liquid so that the liquid fills the outer vessel to cover the inner wall when the compound vessel is positioned upon a supporting surface, whereby the inner vessel and the supporting surface completely enclose the interior space of the inner vessel to fully enclose objects contained therein, said spheroidal shape and said liquid cooperating to magnify objects placed in the interior space viewed from any position on the exterior side of the compound vessel.

A compound vessel formed of a transparent clear material and having a spheroidal main body, comprising spheroidal inner and outer walls with an annular space defined therebetween, the annular space constituting an outer vessel of the compound vessel and the interior space contained by the inner wall constituting an inner vessel of the compound vessel, the outer and inner walls joining at one extremity of the spheroidal main body of the compound vessel to close the outer vessel and form the periphery of a generally circular mouth opening into the inner vessel, said inner vessel being otherwise closed, the outer wall terminating at an opposite extremity of the spheroidal main body of the compound vessel to form the periphery of a generally circular mouth opening into the interior of the outer vessel, said outer vessel being otherwise closed said outer vessel being filled with a transparent clear liquid so that the liquid fills the outer vessel to cover the inner wall when the compound vessel is positioned upon a supporting surface, whereby the inner vessel and the supporting surface completely enclose the interior space of the inner vessel to fully enclose objects contained therein, said spheroidal shape and said liquid cooperating to magnify objects placed in the interior space viewed from any position on the exterior side of the compound vessel.
Claim 3
Dependent Claim
42 words

Claim 4
Dependent Claim
41 words
A compound vessel according to claim 2, in which the mouth of the outer vessel is spaced from the mouth of the inner vessel further than any portion of the inner wall is spaced from the mouth of the inner vessel.
Claim 5
Dependent Claim
16 words
A compound vessel according to claim 2 in which all of said mouths are substantially co-axial.
Claim 6
Dependent Claim
41 words
A compound vessel according to claim 1, in which the mouth of the outer vessel is spaced from the mouth of the inner vessel further than any portion of the inner wall is spaced from the mouth of the inner vessel.
Claim 7
Dependent Claim
16 words
A compound vessel according to claim 1, in which both of said mouths are substantially co-axial.
