SUMMARY OF THE INVENTION 
In view of the foregoing disadvantages inherent in the known types of 
pacifier construction now present in the prior art, the present invention 
provides an infant pacifier construction wherein the same is directed to a 
pacifier employing a nipple head including an outwardly projected and 
tapered head portion for enhanced simulation of a human breast in use. As 
such, the general purpose of the present invention, which will be 
described subsequently in greater detail, is to provide a new and improved 
infant pacifier construction which has all the advantages of the prior art 
pacifier construction and none of the disadvantages. 
To attain this, the present invention provides a pacifier arranged to 
include a base disc mounting a base plug, wherein the base plug is 
directed through the base disc mounting a nipple head. The nipple head 
defines an annular groove between the nipple head and the base plug at a 
front wall of the base disc to enhance grasping of the nipple by an 
infant, wherein the nipple head includes a first inwardly tapered base 
portion extending from the annular base directed to a second outwardly 
tapered base portion, in turn directed to a third inwardly tapered base 
portion that in turn is directed into a nipple head tip, wherein the 
nipple head is canted from the annular base towards the nipple head tip 
defining an undulating outer surface for enhanced grasping by an infant in 
use. The nipple head is arranged to include a cavity to contain a fluid or 
freezable gel to enhance soothing use by the infant. A modification of the 
invention is directed to the fluid accessed to the infant and replenished 
through an access plug directed through the base plug. 
My invention resides not in any one of these features per se, but rather in 
the particular combination of all of them herein disclosed and claimed and 
it is distinguished from the prior art in this particular combination of 
all of its structures for the functions specified. 
There has thus been outlined, rather broadly, the more important features 
of the invention in order that the detailed description thereof that 
follows may be better understood, and in order that the present 
contribution to the art may be better appreciated. There are, of course, 
additional features of the invention that will be described hereinafter 
and which will form the subject matter of the claims appended hereto. 
Those skilled in the art will appreciate that the conception, upon which 
this disclosure is based, may readily be utilized as a basis for the 
designing of other structures, methods and systems for carrying out the 
several purposes of the present invention. It is important, therefore, 
that the claims be regarded as including such equivalent constructions 
insofar as they do not depart from the spirit and scope of the present 
invention. 
Further, the purpose of the foregoing abstract is to enable the U.S. Patent 
and Trademark Office and the public generally, and especially the 
scientists, engineers and practitioners in the art who are not familiar 
with patent or legal terms or phraseology, to determine quickly from a 
cursory inspection the nature and essence of the technical disclosure of 
the application. The abstract is neither intended to define the invention 
of the application, which is measured by the claims, nor is it intended to 
be limiting as to the scope of the invention in any way. 
It is therefore an object of the present invention to provide a new and 
improved infant pacifier construction which has all the advantages of the 
prior art pacifier construction and none of the disadvantages. 
It is another object of the present invention to provide a new and improved 
infant pacifier construction which may be easily and efficiently 
manufactured and marketed. 
It is a further object of the present invention to provide a new and 
improved infant pacifier construction which is of a durable and reliable 
construction. 
An even further object of the present invention is to provide a new and 
improved infant pacifier construction which is susceptible of a low cost 
of manufacture with regard to both materials and labor, and which 
accordingly is then susceptible of low prices of sale to the consuming 
public, thereby making such infant pacifier construction economically 
available to the buying public. 
Still yet another object of the present invention is to provide a new and 
improved infant pacifier construction which provides in the apparatuses 
and methods of the prior art some of the advantages thereof, while 
simultaneously overcoming some of the disadvantages normally associated 
therewith. 
These together with other objects of the invention, along with the various 
features of novelty which characterize the invention, are pointed out with 
particularity in the claims annexed to and forming a part of this 
disclosure. For a better understanding of the invention, its operating 
advantages and the specific objects attained by its uses, reference should 
be had to the accompanying drawings and descriptive matter in which there 
is illustrated preferred embodiments of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
With reference now to the drawings, and in particular to FIGS. 1 to 9 
thereof, a new and improved infant pacifier construction embodying the 
principles and concepts of the present invention and generally designated 
by the reference numerals 10 and 10a will be described. 
More specifically, the infant pacifier construction 10 of the instant 
invention, as indicated in the FIGS. 1-4, indicates the use of a resilient 
base disc 11, having a front wall 12 spaced from a rear wall 13 in a 
parallel coextensive relationship. A base plug 14 is directed orthogonally 
and through the base disc projecting from the rear wall 13 through the 
front wall 12 mounting a nipple head 17 in a spaced relationship relative 
to the front wall 12. A support loop 15 is provided pivotally mounted to 
the rear wall 13 about anchor lugs 16 that are positioned on diametrically 
opposed sides of the rear wall 13, as indicated in the FIGS. 1 and 4 for 
example. The nipple head 17 includes an annular base 18, wherein an 
annular groove 19 is defined between the annular base 18 and the front 
wall 12 to enhance grasping of the nipple, in a manner as indicated in 
FIG. 1, by an infant. The annular base 18 tapers in an undulating manner 
towards a nipple head tip 25. It is understood that the pacifier 10 is 
symmetrically oriented about a central axis 21 relative to the various 
components thereof as described. A first inwardly tapering head portion 22 
extends from the annular base 18 towards the tip, wherein a second 
outwardly tapering head portion 23 tapers outwardly relative to the 
central axis 21 of the first head portion 22, wherein a third inwardly 
tapering head portion 24 extends from the second outwardly tapering head 
portion 23 towards the nipple head tip 25. In this manner, simulation of 
human anatomy, as well as enhanced grasping of the pacifier structure in 
use is effected. 
Reference to FIG. 3 indicates the use of a head fluid cavity 26 positioned 
within the head extending from the plug 14 to the tip 25 containing a 
fluid 27 or a freezable gel therewithin. 
Reference to the FIGS. 5-9 indicates a modified infant pacifier 
construction 10a, wherein in addition to the structure as noted above, an 
externally threaded access plug 28 is threadedly received within a base 
plug internally threaded bore 32 coaxially directed through a modified 
base plug 14a. The access plug 28 includes a slot 30 directed into the 
access plug for ease of disassembling the access plug relative to the 
threaded bore 32 by use of a screwdriver and the like. A vent conduit 31 
coincident with the central axis 21 is directed from the slot 30 into an 
interior port 34, that in turn is in communication with the base plug 
internally threaded bore 32, that in turn is in communication with the 
head fluid cavity 26. The vent conduit 31 (see FIG. 8) includes a 
resilient check valve plate 33 hingedly mounted within the interior port 
34, whereupon suction directed through the vent conduit 31 displaces the 
resilient check valve plate 33 from the vent conduit 31 within the 
interior port 34, whereupon absence of suction by an infant through the 
head fluid cavity 26 releases the check valve plate 33 to again effect 
closure of the vent conduit 31 relative to the interior port 34. 
An annular array of suction conduits 35 are directed through the nipple 
head 17 at the third inwardly tapered head portion 24. Each of the suction 
conduits 35 in communication with the head fluid cavity 26 permits the 
drawing of suction through the fluid cavity 26, wherein preventing 
undesired weepage of fluid through the suction conduits 35, each of the 
suction conduits 35 is formed with resiliently biased conduit wall 36 that 
is closed upon the absence of suction but is displaced in a second position 
from the first closed position upon directing of suction through the 
suction conduits 35 by an infant. In this manner, fluid 27 contained 
within the cavity 26 is accessed through the suction conduits 35 by an 
infant in use and vented through the vent conduit 31. 
As to the manner of usage and operation of the instant invention, the same 
should be apparent from the above disclosure, and accordingly no further 
discussion relative to the manner of usage and operation of the instant 
invention shall be provided. 
With respect to the above description then, it is to be realized that the 
optimum dimensional relationships for the parts of the invention, to 
include variations in size, materials, shape, form, function and manner of 
operation, assembly and use, are deemed readily apparent and obvious to one 
skilled in the art, and all equivalent relationships to those illustrated 
in the drawings and described in the specification are intended to be 
encompassed by the present invention. 
Therefore, the foregoing is considered as illustrative only of the 
principles of the invention. Further, since numerous modifications and 
changes will readily occur to those skilled in the art, it is not desired 
to limit the invention to the exact construction and operation shown and 
described, and accordingly, all suitable modifications and equivalents may 
be resorted to, falling within the scope of the invention.
