Abstract
Abstract An apparatus is set forth including an outer, cylindrical shell formed with a tapered upper end defining an upper opening therethrough for receiving a nursing bottle of predetermined length equal to the axial length of the shell. A plurality of diametrically opposed conduits are intergrally affixed to opposed interior side walls of the shell aligned with fluid indicia formed on an exterior surface of the shell. A chemi-luminescent fluid is contained within a base pouch, the base pouch includes a plurality of spaced arms for reception within the diametrically opposed conduits with a threaded cap secured to a lowermost end of the shell. Remaining nursing fluid within a nursing bottle displaces the chemi-luminescent fluid within the pouch and directs said fluid upwardly for indication of remaining nursing fluid within the nursing bottle based on weight displacement of the nursing bottle on the chemi-luminescent fluid.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
An infant nursing bottle and luminescent fluid indicator apparatus comprising, a transparent outer shell defined by an internal configuration, and a nursing bottle defined by an external configuration substantially complementary to that defined by the internal configuration, and a displacement vessel with at least one conduit member positioned between the nursing bottle and the outer shell, and a chemi-luminescent fluid captured within the displacement vessel, and a cap member including means for securement to a lowermost end of the outer shell to capture the nursing bottle within the outer shell and to capture the displacement vessel between the cap member and the nursing bottle.
Claim 2
Dependent Claim
104 words
An infant nursing bottle and luminescent fluid indicator apparatus comprising, a transparent outer shell defined by an internal configuration, and a nursing bottle defined by an external configuration substantially complementary to that defined by the internal configuration, and a displacement vessel with at least one conduit member positioned between the nursing bottle and the outer shell, and a chemi-luminescent fluid captured within the displacement vessel, and a cap member including means for securement to a lowermost end of the outer shell to capture the nursing bottle within the outer shell and to capture the displacement vessel between the cap member and the nursing bottle.
Claim 3
Dependent Claim
78 words
An infant nursing bottle and luminescent fluid indicator as set forth in claim 1 wherein the outer shell includes diametrically opposed series of fluid indicator indicia portions, and further includes first and second cylindrical chambers positioned interiorly and integrally mounted to interior surfaces of the outer shell diametrically opposed to one another and aligned with the indicator indicia portions, and the first and second cylindrical chambers including lower openings aligned with the lowermost edge of the outer shell.
Claim 4
Dependent Claim
114 words
An infant nursing bottle and luminescent fluid indicator apparatus as set forth in claim 2 wherein the displacement vessel includes a flexible, elliptical base pouch containing the chemi-luminescent fluid wherein the chemi-luminescent fluid is defined by a volume substantially equal to a predetermined volume defined by the base pouch in a first non-stressed configuration, and the at least one conduit member defines a first and second conduit member which are diametrically opposed and in fluid communication with the base pouch, the conduit members defined by a conduit configuration equal to an internal configuration defined by the first and second cylindrical chambers so as to be received by the first and second cylindrical chambers, respectively.
Claim 5
Dependent Claim
31 words
An infant nursing bottle and luminescent fluid indicator apparatus as set forth in claim 3 wherein the outer shell includes a tapered upper end to capture the nursing bottle internally thereof.
Claim 6
Dependent Claim
52 words
An infant nursing bottle and luminescent fluid indicator apparatus as set forth in claim 4 wherein the securement means shell includes a threaded lowermost exterior surface on the outer shell for receiving the cap member and internal threads on the cap member securable to the threaded lower end of the outer shell.
