NURSING BOTTLE AND NIPPLE THEREFOR Filed Nov. 10, 1958 IIII lllll llllllllll INvEN-roR HENRY W. WITZ.

Patented Aug. 15, 1961 ware Filed Nov. '10, 1958, Set. Nb. 773,086

, 1 Claim. (Cl. 2'15-1'1) This invention relates to improvements in nipples for baby bottles and refers particularly to a flexible, resilient nipple so constructed as to provide a vent for the bottle when the bottle is in use to feed the baby, the vented portion of the nipple being protected from injury, when the nipple is inverted in the mouth of the bottle, for storage of the bottle.

The objects and advantages of the invention will be apparent from the accompanying drawing and following detailed description.

In the drawing,

FIG. 1 is a top plan view of my improved nipple positioned for use upon a nursing bottle.

FIG. 2 is a side elevational view of the device shown in FIG. 1.

FIG. 3 is an enlarged sectional view taken on line 3-3 of FIG. 1.

FIG. 4 is an enlarged sectional view, similar to FIG. 3, showing the nipple inverted and a cap applied, for storage of the nipple-bottle assembly.

FIG. '5 is a perspective view of the improved nipple.

FIG. 6 is a fragmentary detailed enlarged sectional view taken on line 66 of FIG. 3.

Referring particularly to the drawing, 1 indicates the upper portion of a conventional nursing bottle, having a neck portion 2 which terminates in a mouth 3, the outer surface of the neck portion carrying screw threads 4. A retaining ring is adapted to seat upon the upper edge of the neck 2, the ring having an annular flange 6, the inner surface of which carries threads 7 which engage with the threads 4 to secure the ring in seated position upon the bottle neck. The ring 5 also comprises a top 8 which is provided with a central aperture 9, the portion of the top adjacent the aperture being offset upwardly to provide an inwardly extending flange 10. The ring 5 may be constructed of hard rubber, a plastic resinous material or the like.

The ring 5 is adapted to secure a flexible, resilient nipple 11 upon the bottle mouth, the nipple embodying the concepts of the present invention. The nipple 11 comprises a body portion 12, a bulbous head portion 13 integrally joined with the body, and an outwardly extending flange portion 14 which is also integral with the body portion and extends radially outwardly from the bottom of the body portion, when the nipple is in its operative position.

When the nipple is assembled with ring 5 and bottle 1, the body portion 12 of the nipple extends loosely through aperture 9 in the top 8 of the ring and the flange 14 underlies the top 8 and rests upon the upper edge of the bottle neck. An annular, triangularly sectioned rib 15 is carried upon the under surface of the top 8 and when the ring 5 is screwed downwardly on the bottle neck, the flange 14 of the nipple is tightly squeezed between the rib 15 and the upper edge of the bottle neck, thereby securely seating the nipple 11 upon the bottle mouth 3.

The dome portion of the bulbous head 13 is provided with apertures 16 whereby the liquid baby food may be extracted by the infant from the bottle. The inner portion of the body portion 12 of the nipple is hollow, and an inwardly extending annular flange 17 is carried by the inner wall of said body portion. The hollow portion of the body, partially defined by the flange 17, is adapted to receive a conventional nipple valve 18, which does not comprise, in itself, a portion of the present invention. There are many types of nipple valves known, and for purposes of the present invention any suitable one may be used. Generally, the nipple valve 18, or any other type of nipple valve which may be used, is a check valve which permits the outflow of liquid baby food from the bottle when the pressure within the bottle momentarily exceeds the pressure within the bulbous portion 13 of the nipple, and closes when the reverse pressure conditions exist.

As has been hereinbefore described, the body portion of the nipple extends loosely within the aperture 9 provided in the ring 5 thereby providing an annular vent space 19. An annular shoulder 20 is carried upon the outer surface of the body portion 12 of the nipple and said shoulder bears upon the flange 10 of the ring top 8. The shoulder 20, however, is provided with a plurality of angularly spaced grooves 21 whereby communication exists from the atmosphere to the annular space 19.

When the ring 5 is screwed down upon the nipple flange 14, by virtue of the oifset'flange 10 upon the top of the ring, an annular space 22 is defined above the nipple flange. The space 19 thus permits communication between space 22 and the atmosphere.

An aperture 23 is provided in the thickness of the nipple flange 14 and the material of the nipple at one end of the aperture is drawn to a tip 24. It will be noted, particularly in FIG. 6, that the thickness of thematerial defining the tip is relatively thin compared to the thickness of the flange and the tip extends outwardly from the base or bottom surface of the flange. The tip 24 is provided with a diametral slit 25' which affords communication, under predetermined conditions, between the interior of the bottle and the aperture 23. Thus, under predetermined conditions the interior of the bottle is vented through the slit 25, the aperture 23, the spaces 22 and 19 and grooves 21 to the atmosphere.

Under normal conditions, that is, when the pressure within the bottle and the pressure within aperture 33 is the same, the resiliency of the material of the nipple will keep the slit 25 closed. If the pressure within the bottle exceeds the pressure within the aperture, as when the bottle is tilted to the infants feeding position, the lips of the tip 24 defining the slit will close the slit tightly. However, when the pressure within the aperture 23 exceeds the pressure within the bottle, that is, after a quantity of liquid baby food has been withdrawn from the bottle by the infant and a partial vacuum is established therein, the slit 25 will open and thus vent the bottle to atmosphere.

When the nipple is not in use for the feeding of the baby, that is, for instance, when it is stored in the refrigerator after sterilizing, the nipple 11 may be inverted on the mouth of the bottle. An imperforate cap 26, comprising a dome-shaped closure 27 having an annular flange 28, may be inserted in the opening 9 of the ring 5-. The flange 28 may be disposed over the nipple flange 14 which is now disposed in inverted position with the tip 24 extending upwardly. It can readily be seen, by reference to FIG. 4, that when the parts are in this position and the ring 5 is screwed downwardly, the lower face of the cap flange 28 will bear directly upon the tip 24, thereby distorting the tip. Such distortion occurring over a period of time will tend to permanently set the tip and it will be destroyed, being incapable of performing its intended function when the nipple is in use.

As a feature of the present invention a bead 29 is formed integral with the nipple flange 14, said head extending away from the surface of the flange in the same direction as the tip 24. The height of the bead from the flange surface is slightly in excess of the height of the screwed downwardly to move the cap flange 28 into contip from said surface and, hence, when the ring 5 is tact with the nipple flange, as shown in FIG. 4, the lower face of the cap flange will contact the bead 29 and thus distort the flange 14 downwardly, thecap flange pressure which would otherwise be sustained by the tip 24, now being sustained by the bead. Hence, the bottle 1 may be completely sealed and the tip 24 remains uninjured.

As can readily be seen from FIG. 5, the bead traverses a large angle of the circumference of the nipple flange 14; the ends of the bead being disposed relatively closely on each side of the tip 24. Hence, the cap flange 28 will bear substantially uniformly on the bead throughout substantially the entire circumference of the nipple flange.

Many modifications of the present invention may be made by anyone skilled in the art, without departing from the spirit of the invention. For instance, the bead 29, instead of being continuous between its ends adjacent tip 24, may be discontinuous, that is, may comprise a plurality of angularly spaced arcuate segments. This and other obvious modifications may be made and are broadly contemplated in the present invention. Hence, it is not intended that the invention be limited to the exact details shown and described except as necessitated by the appended claim.

I claim as my invention:

A nursing bottle assembly comprising a nursing bottle and a nipple wherein the nipple may be stored within the confines of the nursing bottle, said assembly comprising a nursing bottle having a threaded neck defining a mouth, a nipple comprising a hollow body portion, a hollow bulbous portion at one end of the body portion,

an annular shoulder carried on the outer surface of the body portion, a plurality of angularly spaced grooves provided in the shoulder, and a flange at the opposite end of the body portion, said nipple being disposed with the flange portion overlying the mouth of the bottle with the bulbous portion extending into the bottle, said flange portion being provided with an aperture which extends through the thickness of the flange portion, an apertured bulbous tip forming a closure for the aperture in said flange, said bulbous tip extending away from the face of the flange opposite to the body portion of the nipple, a single arcuate bead carried by said face of the nipple flange and substantially in the center thereof, said bead traversing a circumferential line which substantially includes said tip, the ends of the bead terminating a spaced distance short of the tip, the distance of the crest of the head from said face of the nipple flange being at least equal to the distance of the crest of the tip from said nipple flange face, a cap having an annular flange disposed over said face of the nipple flange, and a ring threadedly mounted upon said bottle neck and bearing upon said cap flange to cause said cap flange to bear upon said bead and upon the portion of the nipple flange overlying the mouth of the bottle.
