Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
245 words
A pacifier for infants which emits a whistle sound, the pacifier comprising: a shield having a top section and a bottom section wherein the top and bottom sections are spaced apart from each other except at the periphery of the sections which are joined together; an opening through about the center of the shield top section; a nipple extending vertically away from the shield and secured at its base in the top section opening; an opening through about the center of the shield bottom section; a flexible hollow bulb having an opening at one end for entry and egress of air, the open end of the bulb being secured in the bottom section opening and providing for communication between the interior of the bulb and the interior of the shield; a whistle assembly extending through the bottom section opening into the hollow bulb, the whistle assembly including means for securing the open end of the bulb in place in the bottom section opening; and at least one orifice, in addition to the center openings, in at least one of the shield sections, such an opening to permit the venting or air out from the space between the top and bottom shield sections as the flexible bulb is squeezed forcing air from the bulb through the whistle assembly and into the shield, and to permit air to flow back into the shield, back through the whistle assembly and into the bulb when the bulb is released.
Claim 2
Dependent Claim
245 words
A pacifier for infants which emits a whistle sound, the pacifier comprising: a shield having a top section and a bottom section wherein the top and bottom sections are spaced apart from each other except at the periphery of the sections which are joined together; an opening through about the center of the shield top section; a nipple extending vertically away from the shield and secured at its base in the top section opening; an opening through about the center of the shield bottom section; a flexible hollow bulb having an opening at one end for entry and egress of air, the open end of the bulb being secured in the bottom section opening and providing for communication between the interior of the bulb and the interior of the shield; a whistle assembly extending through the bottom section opening into the hollow bulb, the whistle assembly including means for securing the open end of the bulb in place in the bottom section opening; and at least one orifice, in addition to the center openings, in at least one of the shield sections, such an opening to permit the venting or air out from the space between the top and bottom shield sections as the flexible bulb is squeezed forcing air from the bulb through the whistle assembly and into the shield, and to permit air to flow back into the shield, back through the whistle assembly and into the bulb when the bulb is released.
Claim 3
Dependent Claim
76 words
A pacifier as is claimed in claim 1 wherein the means for securing the open end of the bulb in place in the bottom section opening includes a generally horizontal groove extending around the outer surface of the whistle assembly so that when the pacifier is assembled, the material of the open end of the bulb is held firmly in place in the groove by the flange defining the perimeter of the shield bottom segment opening.
Claim 4
Dependent Claim
16 words
A pacifier as is claimed in claim 1 wherein the shield is circular in horizontal cross-section.
Claim 5
Dependent Claim
53 words
A pacifier as is claimed in claim 1 wherein the nipple is secured in the top section opening by means of a plug which extends through the opening inside the nipple, the plug having an opening through its center which communicates between the lines of the nipple and the inside of the shield.
Claim 6
Dependent Claim
211 words
A pacifier for infants which emits a whistle sound, the pacifier comprising: a hollow shield having a first opening through the center of its top and a second opening through the center of its bottom; a nipple secured at its base in the first opening and extending away from the shield; a flexible hollow bulb having an open end in communication with the second opening to provide for passage of air between the interior of the bulb and the interior of the shield; a whistle assembly extending through the second shield opening into the bulb through the bulb open end, the whistle assembly and the periphery of the second opening trapping the material of the open end of the hollow bulb between them to thereby form a press fit which holds the bulb, the whistle assembly and the shield together; and at least one orifice in the shield in addition to the top and bottom center openings to permit venting of air out from the shield as the flexible bulb is squeezed and air is forced from the bulb through the whistle assembly and into the shield, and to permit air to flow back into the shield, back through the whistle assembly and into the bulb when the bulb is released.
