Abstract
Abstract A doll includes a hollow head and torso and generally replicates a human infant in appearance. The head portion defines an orifice for the introduction of a liquid such as water through simulated nursing. The water is initially received within the doll interior in a first reservoir which is effectively isolated from a second reservoir within the doll torso by a siphon tube coupling. The siphon tube coupling serves to delay the transfer of liquid from the first reservoir to the second reservoir until a predetermined amount of liquid has been introduced. The second reservoir includes a flexible wall portion which bulges outwardly when filled with water to trigger a switch which enables an internally supported sound generating system to produce crying action. In an alternate embodiment, the first and second reservoirs are combined within a common water tank and interconnected by a siphon passage. In the alternate embodiment, the sound generator is enabled by a pair of electrical contacts positioned within the siphon passage.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
147 words
A doll simulating wetting and crying actions for transferring a liquid in a realistic flow rate, said doll comprising: a doll body having an interior cavity, a mouth opening, and a lower body opening; sound means for producing crying sounds; a first liquid receiving and retaining reservoir coupled to said mouth opening; a second liquid receiving and retaining reservoir having discharge means coupled to said lower body opening for producing a flow of liquid from said second reservoir which is independent of the flow between reservoirs; siphon means coupling said first and second reservoirs, said siphon means being inoperative until the liquid within said first reservoir exceeds a predetermined level said siphon means acting to effectively empty said first reservoir to said second reservoir upon actuation; and switch means responsive to the transfer of liquid from said first reservoir to said second reservoir enabling said sound means.
Claim 2
Dependent Claim
147 words
A doll simulating wetting and crying actions for transferring a liquid in a realistic flow rate, said doll comprising: a doll body having an interior cavity, a mouth opening, and a lower body opening; sound means for producing crying sounds; a first liquid receiving and retaining reservoir coupled to said mouth opening; a second liquid receiving and retaining reservoir having discharge means coupled to said lower body opening for producing a flow of liquid from said second reservoir which is independent of the flow between reservoirs; siphon means coupling said first and second reservoirs, said siphon means being inoperative until the liquid within said first reservoir exceeds a predetermined level said siphon means acting to effectively empty said first reservoir to said second reservoir upon actuation; and switch means responsive to the transfer of liquid from said first reservoir to said second reservoir enabling said sound means.
Claim 3
Dependent Claim
16 words
A doll as set forth in claim 1 wherein said first and second reservoirs are vented.
Claim 4
Dependent Claim
22 words
A doll as set forth in claim 1 wherein said doll body defines head and torso cavities connected by a neck passage.
Claim 5
Dependent Claim
28 words
A doll as set forth in claim 3 wherein said first reservoir is supported within said head cavity and said second reservoir is supported within said torso cavity.
Claim 6
Dependent Claim
34 words
A doll as set forth in claim 4 wherein said siphon means are supported within said first reservoir and wherein said doll includes a hollow tube coupling said siphon means to said second reservoir.
Claim 7
Dependent Claim
40 words
A doll as set forth in claim 5 wherein said second reservoir includes an expandable portion which expands when said second reservoir receives liquid and wherein said switch means include a switch having an actuator moved by said expandable portion.
Claim 8
Dependent Claim
20 words
A doll as set forth in claim 6 wherein said expandable portion of said second reservoir includes a flexible wall.
Claim 9
Dependent Claim
146 words
A doll simulating wetting and crying actions for transferring a liquid in a realistic flow rate, said doll comprising; a doll body having an interior cavity, a mouth opening, and a lower body opening; sound means for producing crying sounds; a water tank supported within said interior cavity and wherein first and second reservoirs are enclosed with said first reservoir coupled to said mouth; said second reservoir having a discharge means coupled to said lower body opening for producing a flow of liquid from said reservoir which is independent of flow between reservoirs; siphon means coupled to said second reservoir being inoperative until liquid within said second reservoir exceed a predetermined level whereupon said siphon means acts to effectively empty said second reservoir to said lower body opening; and switch means responsive to the transfer of liquid through said siphon means thereby enabling said sound means.
Claim 10
Dependent Claim
146 words
A doll simulating wetting and crying actions for transferring a liquid in a realistic flow rate, said doll comprising; a doll body having an interior cavity, a mouth opening, and a lower body opening; sound means for producing crying sounds; a water tank supported within said interior cavity and wherein first and second reservoirs are enclosed with said first reservoir coupled to said mouth; said second reservoir having a discharge means coupled to said lower body opening for producing a flow of liquid from said reservoir which is independent of flow between reservoirs; siphon means coupled to said second reservoir being inoperative until liquid within said second reservoir exceed a predetermined level whereupon said siphon means acts to effectively empty said second reservoir to said lower body opening; and switch means responsive to the transfer of liquid through said siphon means thereby enabling said sound means.
Claim 11
Dependent Claim
29 words
A doll as set forth in claim 8 wherein said water tank defines a first interior wall and first and second reservoirs are separated by said first interior wall.
Claim 12
Dependent Claim
32 words
A doll as set forth in claim 9 wherein said siphon means includes a second interior wall forming a generally U-shaped member about said first interior wall forming a siphon passage therebetween.
Claim 13
Dependent Claim
23 words
A doll as set forth in claim 10 wherein said switch means include a pair of electrical contacts disposed within said siphon passage.
Claim 14
Dependent Claim
19 words
A doll as set forth in claim 11 wherein said electrical contacts include electrodes supported in a spaced-apart arrangement.
