L. D. MILES NIPPLE AND DISPENSING DEVICE Feb. 5, 1952 INVENTOR. 08%

Filed Oct. 3, 1947 Patented Feb. 5, 1952 UNITED STATES PATENT OFFICE NIPPLE AND DISPENSING DEVICE Lawrence D. Miles, Baltimore, Md.

Application October 3, 1947, Serial No. 777,635

8 Claims.

This invention relates to dispensing nipples and devices, particularly to the types of dispensers and nipples used for the feeding of infants.

In nursing units of the prior art the rate of flow is largely determined by the varying size of a small orifice through unstable rubber type material. An orifice large enough for proper feeding causes too much leakage on the clothing, and, by flowing when the infant is not sucking, chokes him. An orifice small enough to prevent these difliculties requires long hard sucking and much air is taken into the stomach.

The result is that holes, too small for proper feeding are usually used. These holes close as the rubber swells and disintegrates under successive sterilizings. They are periodically enlarged with a hot needle by unskilled users, usually resulting in over size openings which cause choking and spillage until they partially close again.

This entirely haphazard situation is eliminated in my feeding device by using an orifice large enough so that the rubber will never swell sufficiently to appreciably decrease the orifice area. All leakage and choking are prevented by the nature of operation of the device as later disclosed.

A suitable feeding device must (1) continuously provide food at the proper rate in exchange for the proper effort; (2) not leak when the device is in nursing position but not in use and (3) not allow seepage when the infant is not expending effort upon the nipple. The first property minimizes the swallowing of air which causes colic. The second property eliminates wetting of the clothing around the inf-ants face and neck. The third property prevents choking which frequently causes an infant to regurgitate its food.

The object of this invention is, by employing new and useful principles, to prevent flow of liquid food excepting when physical pressure and/or partial Vacuum are applied to the nipple.

It is a further object to provide a nursin unit which will deliver a predetermined quantity of food throughout the life of the unit in response to a given effort.

It is a further object to provide a nursing unit which will not leak when not being used even though inverted in nursing position.

It is a further object to provide a nursing unit which will not allow leakage into the mouth of the infant when he is not expending effort on the nipple.

It is a further object to provide a nursing unit,

the performance of which is not dependent upon the size of small holes which change with successive sterilization and use.

It is a further object to provide a nursing unit which is simple and straightforward to clean, sterilize, and assemble.

With the foregoing objects in view which will be made clear in the following detailed description, reference is made to the accompanying drawings for the illustrative embodiment of this invention.

I am aware that some changes may be made in the arrangements and combinations of the parts and devices as well as in the details of the construction thereof without departing from the scope of the present invention as set forth in the following claims; hence I do not limit my invention to the exact arrangements and combinations described in the said specification, nor to the exact details of the construction of the said parts as illustrated in the accompanying drawings.

Fig. 1 shows a preferred embodiment of the nursing unit as normally closed.

Fig. 2 shows the nursin aperture as opened by physical pressure on the nipple and/or partial vacuum as produced by the nursing infant.

Fig. 3 shows one embodiment of the shield element which operates in conjunction with the nipple to produce a properly opening and closing nursing orifice.

Fig. 4 shows another embodiment of the open and closed orifice principle, also an adapter on which the inner of the two contacting elements is mounted. The adapter can be so constructed as to adapt essentially any nipple to any bottle.

Fig. 5 shows the construction of Fig. 4 as the orifice is opened during use.

Figs. 6 (a) and (b) show the normal and the open views of an alternate construction in which the shield member is made fast to the nipple member and Fig. 6 (0) shows a top plan view of the construction shown in Fig. 6 (a).

Figs. 7 (a) and (1)) illustrate another embodiment of the same principle, normal, and in use and Fig. '7 (0) shows a top plan view of the embodiment shown in Fig. 7 (a).

Figs. 8 (a) and 8 (b) illustrate, in open and closed condition respectively, another embodiment in which the flow of food is throttled or metered out according to the effort expended upon the nursing unit.

Figs. 9 (a), (b) and (c) show modifications adaptable to different styles of nipple mounting in which the shield support is adapted to further meter the fiow of food.

The novelty of my invention consists of several features which will be explained.

The nursing orifice I is normally closed by direct contact between the nipple 2 and the shield 3 so that no leakage occurs in normal relation, as shown by Fig. 1. The nipple 2 and shield 3 are mounted on the top section of .a receptacle such as a nursing bottle 4 by the screw cap 5. When subjected to pressure from the gums and tongue of the infant and partial vacuum from his suctorial pads the members 2 and 3 separate as shown by Fig. 2, the orifice is then open and food flows.

The shield 3 is mounted on any suitable support. One simple and practical design, Fig. 3, mounts under the nipple as shown in Fig. l. Vent groove 6 serves the second necessity for proper operation, namely that of admitting air into the bottle. Openings 7 through the shield mounting allow fiow of food into the nipple. Fluting 8 allows passage of food even though nipple is elongated and compressed.

Similarly in Fig. 4 the orifice 8 located off the center of the nipple, normally closed, is opened when in use by the separation of nipple 2 and a shield member 9. The shield 9 is a hollow cylindrical member and engages at one end a small boss on the inner wall of the nipple when the nipple is closed. The other end of the shield member is supported from an adapter which receives the open end of a nursing bottle or other receptacle (not shown).

In Figs. 6 (a), 6 (b), and 6 (c), I have shown a modification of the construction shown in Figs. 1 and 2 in which a shield member H is supported intermediate the ends of the nipple by means of a flexible spider 12. As illustrated the upper end of the shield engages the wall of the nipple about the orifice I in the normal position of the parts and as shown in Fig. 6 (b) is adapted to be retracted from the end of the nipple by the compression of the nipple wall either by exterior pressure or a partial vacuum created within the nipple.

In Figs. 7 (a), '7 (b), and '7 (c), I have shown a further modification of the construction shown in Figs. 4 and in which the off center orifice 8 is selectively closed by a closure member or shield l3 which is joined to the side wall of the nipple body adjacent the orifice. In use the shield is moved away from the orifice by fiexure of the nipple body.

The modification of my invention shown in Figs. 8 (a) and 8 (b) is very similar to that shown in Figs. 1 and 2. In this modification the shield member [4 is tapered at its outer end and is actually received within the orifice in the closed or normal position of the nipple.

In Fig. 9 (a) I have shown a modification of my invention in which an elongated shield member l5 engages the inner wall of the nipple to close the orifice l in the normal position of the nipple and shield. The member l5 substantially fills the body of the nipple throughout a sub stantial portion of its length and is provided with a longitudinally extending groove IE to control the fiow of fiuid to the upper portion of the nipple. Figs. 9 (b) and 9 (0) show a slightly modified form of my invention in which the shield or closure member I! is provided with a flow controlling groove 18 and also a groove I9 for communication with an opening or air inlet 20 on the side of the nipple body.

What I claim as new and. desire to secure by Letters Patent is:
