Application March 23, 1949, Serial No. 82,992

Claims. (CI: 215-113 My invention relates to nursingbottles and provides one that a baby may learn to drink from.

My nursing bottle is illustrated in the accompanying drawings in which Fig. l is a vertical section thru the' bottle, nipple, and nut; Fig. 2 is a plan View of the bottle: Fig. 3 is a plan view of a modification of the bottle; Fig. 4 is a vertical section on the line 4--4 of Fig. 3; Fig. 5 is a vertical section on the 111185-5 of Fig. 3; Fig. 6 is a Vertical section thru a plain edge fiared portion of a bottle; Fig. 7 is a vertical section showing a nipple constructed to slip over the fiared portion of a bottle; and Fig. 8 is a Vertical section showing another version of a nipple and fiared top bottle.

Thruout the drawings and the specication similar numerals refer to similar parts.

The numeral l indicates a glass bottle of slightly tapered cross-section drawn in at the neck 2 to form an annular shoulder 3. The annular neck 2 is enlarged at ZA above the shoulder 3 to provide space for the rubber nipple 4 and the annular plastic nut 5 which is provided with an interior quarter thread S adapted to engage the exterior quarter thread 'l formed on the interior of the enlarged neck portion 2A of the neck 2. The nut 5 is counterbored to form an interier shoulder 8 adapted to come into contact with the outer annular shoulder 9 formed on the exterior surface IOA of the nipple 4 so that the bottom I& of the nipple 4 may be brought into contact with the top surface of the shoulder 3 of the bottle I to form a leakproof joint as the nut 5 is tightened. This tight joint should be made before the bottom of the nut 5 comes into contact with said shoulder 3. Above the enlarged neck portion 2A the neck is again fiared out to approximately the diameter of the base Il of the bottle l. The annular fiared portion z may terminate as shown in Fig. 6, or it may terminate in a lip or bead as shown in Figs. 1 to 5. The bead !3 helps direct milk to the deepest portion of the annular fiared portion l2 as the bottle l is tilted to drinking position and breaks the flow-over as the bottle is lowered from drinking position. Figs. 3, 4, and 5 show the top surface !ZA of the fiared portion 12 concavely fol-med and slightly fiuted, six fiutes [4 being shown with the numeral 15 indicating the ridge l5 of a flute. The fiutes |4 provide additional help toward directing the milk to the mouth of the drinker. Fig. 5 is a section thru the ridge [5. It is to be noted that these ridges 15 strengthen the overhanging fiared por- 2, tion I2. The annular fiaredportion [2 naturally forms an undercut' portion I S which provides the necessary space for' the' baby's lower` lip regardless of what side of the bottle he or she is drinking from.

Fig. ?indicates that a nipple 4 may be designed to hook over a wide mouth bottle as well as over a small mouth bottle. In other words, a nipple 4 may be designed to hook over the undercut portion IS of the fiared annular portion z..

Fig. 8 shows another modification of a nipple adapted for use With a wide mouth bottle. In this instance, the interior'surface' IT of the milk'- holding portion l8 of the bottle converges only slightly to form the restricted neck portion 2' and then fiares outwardly to form the enlarged or intermediate neck portion ZA' and incidently the annular shoulder 3'. The annular fiared portion !2 may terminate as previously described and shown or it may have other configuration without departing from the basic idea. The lower end |9 of the rubber nipple 4 is made cylindrical in form and of a diameter slightly larger than the diameter of the restricted neck 2' so that when it is shoved down into position,

as a cork, it will be compressed at the neck 2' and expanded below and above said neck 2', thereby holding the nipple securely and tightly in place. The nipple 4 is fiared above its lower cylindrical portion [9 to the contour of the top surface |2A of the fiared portion l2 and terminates in an annular fiange 20 which rests upon the top of the bottle l when the nipple is in place and extends beyond the fiared portion l2 about so that the perimeter of the fiared portion 12 is kept from coming into contact with a table for instance when the bottle I is resting on its side. When it is desired to put the nipple 4 on the bottle l the flange 20 is held between the thumb and foreflnger and set on the bottle the cylindrical portion 19 being guided and centered by the converging annular portion !2. Pressure is then applied to the top surface 20A of the annular fiange 20 and the nipple pressed into place where it is held by the shoulder 2' which indents the soft cylindrical portion !9. To remove the nipple opposite sides of the annular fiange 20 are pressed together and incidently the cylindrical portion l9 whereupon the nipple may be lifted from the bottle.

What I claim a-s new over the prior art in nursing battles is set forth in the appended claims.

I claim:

1. A nursing bottle comprising a bottle ormed with an interior shoulder, an interior thread, and an annular fiared neck portion, a nipple having an exterior annular shoulder, and a nut formed with an interior annular shoulder adapted to engage the nipple shoulder and a thread adapted to engage the bottle thread to bring the bottom of the nipple tight against the bottle shoulder.

2. In a nursing bottle in combination with a nipple and a nut provided with a thread and adapted to clamp the nipple to the bottle, a bottle formed with an intermediate neck portion to receive the nipple and nut within and provided with a thread to engage the nut thread, a smaller lower neck portion positioned to form an interior annular shoulder between said neck portions for the nipple to be clamped against and a larger upper neck portion flared outwardly.

3. In a nursing bottle in combination with a nipple and a nut provided with a thread and adapted to clamp the nipple to the bottle, a bottle formed with an intermediate neck portion to receive the nipple and nut within and provided with a thread to engage the nut thread, a smaller lower neck portion positioned to form an interior annular shoulder between said neck portions for the nipple to be clamped against and a larger upper neck portion concavely flared outwardly.

4. In a nursing bottle in combination with a nipple and a nut provided with a thread and adapted to clamp the nipple to the bottle, a bottle formed with an intermediate neck portion to receive the nipple and nut within and provided with a thread to engage the nut thread, a smaller lower neck portion positioned to form an interior annular shoulder between said neck portions for the nipple to be clamped against and a larger upper neck portion eonoavely flared outwardly and having its top surface fluted.

5. In a nursing bottle in combination with a nipple and a nut provided with a thread and adapted to clamp the nipple to the bottle, a bottle iormed with an intermediate neck portion to receive the nipple and nut within and provided with a thread to engage the nut thread, a smaller lower neck portion positioned to form an interier annular shoulder between said neck portions for the nipple to be clamped against and a larger upper neck portion fiared outwardly and terminating in a beaded edge.
