July 15, 1969 M. MUDRINICH INFANT'S PACIFIER WITH MAGNETIC NIPPLE Filed Aug. 8, 1968 FIG.5

FIG.4

INVEN'IOR. MILAN MUDRINICH ATTORNEY United States Patent 3,455,292 INFANTS PACIFIER WITH MAGNETIC NIPPLE Milan Mudrinich, 3325 92nd St., Jackson Heights, N.Y. 11372 Filed Aug. 8, 1968, Ser. No. 751,179 Int. Cl. A61h 17/00 U.S. Cl. 128-1.4 7 Claims ABSTRACT OF THE DISCLOSURE A bar magnet is contained within the hollow resilient nipple of an infants pacifier to provide a magnetic nipple for extraction of magnetizable metallic objects from the infants mouth.

Infants are prone to insert into their mouths small objects within their reach. Among such objects are dangerous things such as, for example, tacks, pins, nails and the like made of magnetizable material. It is usually difli cult for an adult to grasp and remove such an object from the infants mouth, as the infant usually resists inserting ones fingers into the month. However, many infants become acquainted early in life with pacifiers, so that upon seeing a pacifier approaching the infant immediately opens his mouth to permit insertion of the nipple. Moreover, they tend to hide things between the gums and the check, where ones fingers cannot readily reach; the nipple of the present invention can readily reach the object and extract it. The instant magnetic nipple need not, in fact, come into actual contact with the objects, for the object is drawn to the nipple even when the latter is only near to the object.

Referring briefly to the accompanying drawing, FIG. 1 is a view illustrating a step in the application of the instant pacifier.

FIG. 2 is an exploded perspective view.

FIG. 3 is a side view of the pacifier, with parts broken away and partly in section.

FIG. 4 is a fragmentary exploded side view, with parts broken away and partly in section, illustrating a preferred detail of construction.

FIG. 5 is a fragmentary view similar to FIG. 3 but showing a modified magnet construction.

Referring in detail to the drawing, the numeral designates a ring or handle which is shown pivotally attached to an enlargement or knob on one end of a stem 12 provided at the other end with a circumferential groove 13. A hollow flexible, teat-shaped resilient nipple 14, preferably made of rubber, has at its smaller or reduced end an opening into the chamber enclosed by the nipple and is provided with a flange or bead 15 which is stretched and pulled over the stem to register in the groove 13. The portion of the nipple immediately adjacent the flange 15 constitutes the neck of the nipple.

A washer-shaped disc 16 having a center hole 17 serves its usual purpose as a shield or stop as well as aiding in constraining the nipple against detachment from the stem 12. The structure so far described including the ring 10-, the stem 12 and the shield 16 which are all usually made of a more or less rigid plastic material, and the nipple 14 is well known as are also modifications of such structure.

Before passing the reduced open end of the nipple through the hole 17 and engaging the flange 15 in the groove 13, a preferably cylindrical bar magnet 18 is inserted into the nipple. Where the bar magnet is of relatively small diameter, a cap 19 of either magnetizable or non-magnetizable material but preferably made of plastic, is applied over one end of the bar 18, that is, the end which is to be positioned adjacent the disc 16. The cap ice may be frictionally held in place, or it may be glued or cemented to the bar.

The magnet including the cap 19 is first inserted into the nipple by stretching the neck 20 and flange 15 in an obvious manner, whence they both retract and reduce the open end of the nipple thus confining the magnet therewithin. Hence, if from whatever cause the nipple should become detached from the pacifier while in an infants mouth, the magnet cannot escape from the nipple so that the infant cannot swallow it.

With the capped magnet within the nipple as shown in FIG. 3, the flanged end of the nipple is pulled through the disc hole 17 and stretched about the stem 12 to register in the groove 13, thus completing the assembly of the pacifier. Preferably but not necessarily the cap 19, or the end of the magnet having the cap shown thereon, has a slightly larger diameter than that of the hole 17.

When it is suspected that the infant may have an object made of magnetizable material in its mouth, a person applies the pacifier to the infant in the usual manner, exemplified in FIG. 1. Owing to its familiarity with such a device, the infant will open its mouth as the nipple approaches, and the person can then work it about the mouth to cause the object to cling to the nipple, as illustrated, for example, by the tack shown in phantom in FIG. 3. The object is thus readily extracted.

It is apparent that the nipple with the magnet therein may also be used as a teether, for the magnet provides a resistant core to the rubber nipple while the rubber of the nipple provides a yieldable resilient cover about the core. Moreover, the tight closure of the neck 20 about the adjacent circumferential edge of the magnet provides a substantially air-tight closure of the nipple so that the air confined about the magnet further cushions the nipple when compressed.

In FIG. 5 a modified construction is shown, in that the bar magnet 18a has a diameter equal to that of the cap 19 of FIG. 3 and therefore lacks such a cap, since the retraction of the neck 20 about the adjacent end of the magnet similarly constrains the magnet from escaping out of the nipple.

Obviously the bar magnet may be of unitary solid construction, as shown, or, to reduce its weight, it may be made tubular or hollow or have portions thereof gouged out, not shown.

What is claimed and desired to be secured by Letters Patent is as follows:

1. In an infants pacifier which includes a hollow tearshaped nipple of resilient material having a reduced end and enclosing a chamber having an opening thereinto through said reduced end, a handle, and means interposed between the nipple and the handle for securing the nipple to the handle, the improvement consisting of a bar magnet mounted in said chamber and positioned substantially longitudinally with respect to the nipple, at least that end of the magnet which is adjacent said opening having a diameter larger than the diameter of the unstretched openin-g whereby the portion of the nipple adjacent said opening is deformed radially inward against said adjacent end of the magnet to prevent the magnet from escaping through said opening.

2. In an infants pacifier according to claim 1, said improvement consisting additionally of a shield provided with a center hole therethrough, said shield surrounding said portion of the nipple adjacent said opening.

3. In an infants pacifier according to claim 2, said center hole having a diameter smaller than said diameter of said adjacent end of said magnet.

4. In an infants pacifier according to claim 3, wherein said means comprises a stem having said handle at one end thereof and a circumferential groove at the other end thereof, said nipple including a flange surrounding said opening thereinto, said flange registering under tension in said groove.

5. In an infants pacifier including a handle, a stem having said handle secured thereto at one end thereof and having a circumferential groove at the other end thereof, a hollow teat-shaped nipple of resilient material having a reduced end provided with an opening into the nipple and a flange surrounding said opening, a bag magnet mounted within said nipple with that portion of the nipple immediately adjacent said flange under tension and deformed radially inward about the adjacent end of the magnet thereby preventing the magnet from escaping from the nipple, a shield having a center hole therein, said portion of the nipple extending through said hole, said flange registering under tension in said groove.

6. An infants pacifier according to claim 4, said magnet having a cap on that end thereof which is adjacent to said opening into the nipple thereby enlarging the diameter of said end of the magnet.

7. An infants pacifier according to claim 5, said center hole in said shield having a diameter smaller than the diameter of said adjacent end of the magnet.
