NIPPLE FOR NURSING-BOTTLES.

' Specification of Letters Patent Patented May 5, 1914.

Application filed April 18, 1911. Serial IlTo. 621,879.

. Bottles, of which the following is a specification.

This device consists of a teat telescoping upon itself and having its free endprojeoting outwardly to form a nipple, the teat being usually formed with an air inlet arranged to open into the space between the opposing walls of the telescoping portions, and one of said opposing walls having an annular flangewhich projects toward and engages the other of said opposing walls and acts as means for preventing outflow through the opening.

This invention relates to improvements in teats or nipples for nursing bottles and has for its object to provide a nipple so constructed that it will admit air into a bottle as liquid is being withdrawn therefrom.

(Vith the above and other objects in view,

I I have invented the nipple illustrated in the accompanying drawings, in which,

Figure 1 is. a longitudinal sectional view of a bottle and my improved nipple, Fig. 2

is a vertical sectional view of a nipple removed from the bottle and shown collapsed, Fig. 3 is a vertical sectional view of a modifled form of the nipple, Fig. 4 is a top plan view of Figs. 1 and 2, Fig. 5 is an elevational view of the nipple straightened out, Fig. 6 is a longitudinal sectional view through a modified form of the invention,

Fig. 7 is an elevational view of Fig. 6, the nipple end being removed, and Fig. 8 shows a verticalsectional view of the modified form attached to a bottle.

Referring to the accompanying drawings 1 indicates a flexible nipple provided with an opening 2 in its end 3. Extending upward from the lowermost portion 4 of the nipple is a collar 5 which is provided with an overlapping portion 6 which is adapted to slip over the rim 7 and upper portion 8 of the crucible shaped bottle 9 thereby holding the nipple securely onto the bottle.

On the portion 5 is a circumferential flange 10 extending toward the nipple proper, its outer edge 11 normally contacting same entirely therearound, the flange remaining always in a fixed position as indicated in Figs. 1 and 2. The nipple and the flange are so formed that a space 12 is left therebetween and apertures 13 and 14 are provided in the lower portion 4 connecting with the space 12 whereby air may enter said bottle at the moment the nipple is collapsed in sucking milk from the bottle. The nipple being pressed away from the edge 11 of the flange as shown in Fig. 2 permits the air to enter the space 12. When the hold on the nipple is released it again engages the flange and closes the opening 14 into the space 12.

In Fig. 3 I show a. modified form of the invention in which two nipple engaging flanges 15 and 16 are provided whereby an extra precaution is taken to prevent any liquid from passing from the inside of the bottle through the apertures 13 and 14 to the outside of the nipple. By using a nipple of this construction an infant is saved from wind colic as it is prevented from sucking wind into its stomach in its effort to suck milk from a collapsed nipple as this nipple will never remain collapsed when pressure thereagainst is removed the air entering the bottle through the apertures 13 and 14 being sufficient to compensate for the milk withdrawn from the bottle, thus no vacuum is formed in the bottle to hold the nipple collapsed.

In Figs. 6, 7 and 8 I show another modified form of the invention in which the mem ber 17 has an opening 18 in its upper part and is provided with a rim 19 around said opening whereby an ordinary nipple may be secured thereto; otherwise the device is the same as that above described.

This improved nipple is very sanitary as it may be straightened out for cleansing as shown in Figs. 5, 6, and 7, and being flexible may be readily turned inside out for washng.

- I claim and desire to secure by Letters Patent,

1. A teat for nursing bottles, the teat comprising a collapsible nipple having an outlet opening at its free end, the teat also being formed with an inlet for air, and

' means operated by the collapsing action of 1 the nipple for permitting air to pass through the inlet, substantially as and for the purpose described.

2. A teat for nursing bottles, the teat tcomprising a collapsible nipple having an outlet opening, an air inlet opening, and external means for controlling the flow of air through the latter opening, said means normally engaging the periphery of the nipple, and portions of the nipple being movable out of engagement with said means during the collapsing of the nipple and thereby permitting the inflow of the air, Eubstantially as and for the purpose speci 3. A teat for nursing bottles, the teat comprising a collapsible nipple having an outlet opening, an air inlet opening, and an exterior annular flange normally engaging the periphery of the nipple above the air inlet opening and thus preventing the air from entering through such inlet opening, portions of the nipple moving out of engagement with the annular flange during the collapsing of the nipple and thereby permitting the air to enter the inlet opening and fill the partial vacuum within the nipple, substantially as and for the purpose set forth.

4. A teat for nursing bottles comprising a collapsible nipple having an outlet opening, the teat also having an air inlet opening and means coacting with the nipple for normallv closing the air inlet opening, portions of the nipple being movable out of engagement with said means during the collapsing of the nipple, and thereby opening the air inlet opening, substantially as and for the purpose described.

5. A teat for nursing bottles comprising a collapsible nipple having an outlet opening, at its free end, the teat also having an air inlet opening near the inner end of the nipple, the teat being also formed with a flange normally engaging .the periphery of the nipple above the air inlet opening, portions of the nipple being movable out of engagementwith the flange during the collapsing of the nipple and thereby permitting the air to enter the air inlet opening, and fill the collapsing nipple, substantially as and for the purpose specified.

6. A teat for nursing bottles, the teat being telescopic upon itself, and the inner portion thereof constituting a nipple, and having an outlet opening at its free end, and the teat being formed'with an inlet for air, opening into the space between outer and inner portions thereof when the teat is telescoped upon itself, and one of said portions being provided with means projecting across such space and engaging the other portion to control the passage of air in said inlet, substantially as and for the purpose set forth.
