Application January 29, 1942, Serial No. 428,883

2 Claims.

This invention relates to bottles and dispensing spouts and nipples for bottles, particularly to the types of bottles and nipples used for nursing.

An object ofthe invention is to provide a novel construction for nursing bottles and nipple holders as well as nursing bottle nipples which can be used without unduly clogging the passage for dispensing the contents of the bottle, and in which atmospheric pressure is admitted to the fluid level of the bottle without bubbling through or otherwise filling the fluid in the bottle with small air bubbles, and whereby the dispensing of liquid as well as emulsied vegetableor food are facilitated.

Particularly it is an object of the invention to provide a nursing bottle in which air is admitted above the level of the liquid while the bottle is held in a natural dispensing position, or in such a way that a nipple in use is filled' with the contents of the bottle under atmospheric pressure admitted into the bottle at a point other than the passage of the nipple in use. This is an important feature 'of my invention because when, as in the previous practice, air is admitted through the holes at the nipple in use, such air forms bubbles in the bottle. Frequently these bubblesv do not break. Such small bubbles when swallowed by an infant yin nursing remain mixed with the liquid in the digestive tract and are frequently the cause of colic or similar disorder.

Another object of this invention is to provide convenient, easy, and adjustable means for regulating the fiow of liqu'id from the bottle through lthe dispensing spouts or nipples of the bottles. In the present illustration this regulation is accomplished by adjustable partial obstruction across the path through which liquid from the bottle is dispensed.

A still further object of the invention is to provide an attachment for'bottles of the character described whereby a bottle of a single opening or neck can be converted into a bottle with a double neck or two spouts so arranged that air is admitted through one of the spouts while the other is in use; each of these necks or spouts being adapted to accommodate a suitable dispensing element such as the usual nursing nipple; the necks or spoutsibeing divergent at such an angle that the liquidI will not spill out of either the spout or neck when the other spout is in use, in other words the liquid level will not reach over and above the spout .used for ventlv provide a nursing nipple the connection of which with the spout or neck of a dispensing bottle is such as to allow easy regulation of coacting elements to regulate the speed of flow through said nipple, the means for such regulation being also provided with passages which are self-cleaning.

Another object of this invention is to provide a nursing bottle and nipples which are highly useful and simple in construction. Convenience of arrangement, lightness, and comparative inexpense of manufacture are further objects which have been borne in mind in the production and development of the invention.

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

With the foregoing and other objects in view, which will be made manifest in the following detailed description, reference is had to the accompanying drawings for the illustrative embodiment of the invention, wherein: c

Fig. 15 is a fragmental plan view of a substantially oval shaping of the mouthpiece of a nipple on applicants invention for locating the bottle at the correct angle.

In carrying out my invention, as shown in the illustrative embodiments I make use of a cylindrical bottle I6, the ends of which are open so as to facilitate the cleaning of the bottle I6. At

the top end I 1 of the bottle I6 a dispenser device f is provided which in the forms shown in Figs. 1 and 2 allows for the automatic maintenance of atmospheric pressure above the level of the contents of the bottle during the dispensing from the bottle I8, or the bottle 23, the bottom of such bottle is provided with a. removable .bottom cap said bottle I6. In ,the form shown in Fig. 1 a

cap I8 is removably attached to the top end I'I of the bottle I6. In this illustration the cap I8 is secured in place by threaded engagement. The cap I8 has two dispensing spouts kor necks I8 and 2| which are located diametrically opposite on the top of the cap I8'. The necks I9 and 2l diverge outwardly of the cap I8 and at such angles that when the bottle is in tilted position, the level of the liquid or emulsified food in the bottle is below the rim of the neck I9 or 2i whichever is not in use for dispensing. This is accomplished by making the necks I9 and 20 of suitable length in addition of having them at suitable angles for convenient use.

This cap I8 as well as the necks -I9 and 2| may be made of glass, plastic, or Lucite, rubber or synthetic rubber, or of other material suitable for the particular liquid orA emulsions. A nursing nipple 22 is detachably connected to one of said necks in the herein illustration to neck 2 I. During feeding the other neck I9 functions as the air vent so that the feeding through the nipple 22 is accomplished under atmospheric pressure on the liquid, which pressure is admitted at a point remote from the cavity of the nipple 22. In this manner the formation of air bubbles and the circular motion or eddying of the air within the cavity of the nipple 22 is obviated and a continuous ow of the contents of the bottle I6 through said nipple 22 facilitates the feeding through such nipples.

In the form shown inFig. 2 a nursing bottle 23 is formed with integral necks 24 and 26 which extend from the closed top 2'I of the bottle 23 to such a distance and at such diverging angles as to permit the use of one of said necks as a vent when the other neck is at dispensing angle.

This double neck arrangement on the bottle 23 may be also used in the same manner as heretofore described in the first form of the invention, although it is believed that the use of a cap attachment on a tubular bottle is more practical in view of the greater facility for cleaning and disinfecting both the bottle and the dispensing device on the bottle. l

In order to further facilitate the admission oi' air above the level of the contents of such container and to further facilitate the cleaning of 28. This cap 28 is preferably threadedly secured on the exterior of the bottom end of the bottle I6. A resiliently compressible gasket 29 is provided between the bottom cap 28 and the bottom 3I of Vthe bottle I6, so as to seal the cap 28 in place at various adjustments. The admission of air at the bottom of the bottle is regulated by turning the bottcm cap 28. In the herein illustration a groove 32 extends partly in the bottom of the cap 28 and then acrossl the threads on the side vertically to the rim of the cap 28. The resilient gasket 29 completely fills the groove 32 at the bottom of the cap 28 when the cap 28 is tightened so as to seal the bottom of the bottle. When the cap 28 is loosened the gasket 28 is gradually withdrawn from the groove 32 according to the degree of turning of the cap 28 and thus allows the passage of air through said groove 32. In this manner the air pressure admitted therethrough is regulated which in turn regulates the speed of flow through the outlet nipple at the top of the container or the bottle I6 or 23.

In connection with the various modifications of the regulating and dispensing devices and nipples shown in this application, the admission of air may be accomplished either by the use of a double neck structure as heretofore described, or by the use of an air vent regulating device at the bottom of the bottle, or by other suitable air vents at points outside of the cavity of the nipples and above the level of the contents of said bottle durving dispensing. The various modiiications of my invention are illustratedon a neck fragmentally shown, but it is to be understood that such nipples and regulating devices, per se, may be used directly on the single neck of a usual bottle as well as on either ofthe double necks of a structure heretofore described.

Feeding or nursing through such bottles must bey frequently accomplished at varying rates of speed to suit the food or the conditions of feeding. In order to provide for easy adjustment and regulation for light liquids as well as for more dense food emulsions, I provide an adjustable regulating device herein whereby the opening of the passage through the necks of the containers or bottles can be quickly and accurately changed and determined.

In the form shown in Fig. 1 this regulation is accomplished by providing a recess 35 in each neck I8 and 2|. A resiliently compressible gasket 33 is placed in this recess 35. The recess is larger than the gasket 33 to provide clearance for a comparatively large degree of compression of the gasket 33 within the recess 35. This gasket 33 is of a frictional material. Over this gasket 33 is placed an apertured disc 34 which is held against rotation relatively to the neck by the frictional Vengagement of the gasket 33 both with the recess 35 and with the disc 34. Upon this comparatively stationary disc 34 is superimposed a second relatively movable apertured disc 36, which latter in turn is held in a small cap 3l threadedly secured on each neck I9 and 2l. It is to be noted that the movable disc 36 is so located inside of the cap 31 that it turns with the cap 31. The meeting surfaces of the discs 34 and 36 are smooth so as to allow relative adjustment of the disc 36 While the discs are held against each other by the resiliently compressible gasket 33. The apertures in the discs 34 and 36 are so ofiset relatively to each other that they register to a degree determined by the relative positions of said dises. The aperture er the cap s1 is located opposite the area of the apertures of the stationary disc 34 so as to allow a clear passage through the adjusted registering apertures of the super-imposed discs 34 and 36.

In the form shown in Fig. 1, the same regulation is provided both on the neck 2| used for dispensing as well as on the neck I9 which is shown in use as an air vent. By adjusting the discs under the nipple 22` the rate of flow into the nipple can be regulated. By adjusting the other set of discs on the other neck I9 the rate ofnair inflow is regulated so as to control accurately the rate of feeding through the nipple 22.

In the form illustrated in Fig. 2 the regulation is shown as accomplished solely by the adjustment of the air intake. In this form the nipple is attached to the neck 26 which is provided with a wide unobstructed passage into the nipple. On the other hand the other neck 24 of this form has on it the regulating device heretofore described whereby the air intake can be regulated for controlling the flow into the nipple.

In the above forms the necks are interchangeable in use, In the form in Fig. 1 the interchanging can be accomplished by simply transferring the nipple 22 from the neck 2| to the neck I9 or vice versa. In some instances a nipple may be placed on both of the necks and the nipples could be used interchangeably. In the illustration shown in Fig. 2 the regulating device and its cap are transferred to the neck 26 and the nipple is placed on the neck 24 and vice versa for interchange of function. .The feature of interchanging these openings especially the interchanging of the use of the regulating devices has the advantage of dislodging'of any particles that might stop up the opening through said discs. For instance, if the device on the neck 2| is clogged up by some small solid or coagulated particles, then, upon the interchanging of the use of the necks I3 and 2|, the suction inwardly through the neckl 2| when it is used as an air vent will dislodge such particles from the disc openings.

The apertures 38 in the discs 34 and 36 maybe either of the types shown in the Figuresv, '1, 8, and 9. It is to be noted that these discs may be either used as a lower or as an upper disc. Each of these discs has an ear 39 of irregular, such as trapezoidal outline, which Ais engaged by a suitable slot 4| in the side of the neck or in the side of the cap in the manner illustrated in Fig. 13, so as to properly locate the respective discs. The lower disc 34 is thus held against movement relatively to the neck I9 or 2| by this engagement of its ear 39 with the corresponding slot 4|' in said neck. 'I'he upper disc 36 is similarly held in operative connection with the cap or with the nipple by its ear 39 connected to corresponding slot 4| in said cap or nipple. The apertures 38 on the two discs are arranged circumferentially on the same radius so that the registering of the respective apertures is regulated by turning the top disc 36 relatively to the lower disc 34. For instance in the form shown in Fig. 6 the discs 34 and 36 have elongated arcuate slots 38 on the same radius. 'I'hese arcuated slots 38' are in registry with each other according to the rotative or angular adjustment of the top disc 36 relatively to the bottom disc 34. The aperture in the form shown in Fig. 7 is in the form of a pair of larger spaced but also arcuate holes 38". The openings of the top disc then align with both of these openings in accordance with the relative angular adjustment. In the form shown in Fig.

4 and Fig. 8 the lower disc is providedwith a series of arcuately arranged spaced holes 42 of progressively increasing size. As shown in Fig. 4 the top disc in this case has only one single opening 43 which aligns with a smaller or a larger hole 42 according to the angular adjustment of the top disc relatively to the bottom disc. In this form the flow is regulated according to the size of the hole 42 which is aligned with and uncovered by the controlling upper aperture 43. This form also shows the tapering of the holes 42 inwardly of the bottle so as to facilitate the dislodging ci' coagulated or other clogging particles from said holes. Another form, as shown in Fig. 9, has a group of smaller holes 44 on one side and one large hole 46 diametrically opposite therewith, which are aligned and opened and closed by a single control aperture in a top disc such as the type of holes 43 of Fig. 4 and by the angular adjustment hereinbefore described. Other suitable aperture arrangements may be provided to accommodate the type, the density or consistency of the substance, or food or liquid to be dispensed through said regulating device. In connection with nursing bottles the regulation of such apertures allow y variable control for the various types of formulas for feeding infants, and each such formula can be fed at a suitable rate of speed.. These discs may be made of transparent or any plastic or similar suitable material.

` In the formshown in Fig. 4 the upper disc isv formed by the top of the cap 41 in other respects the device operates as heretofore described. Fig. 5 illustrates the use lci? a cap 48 on the neck .4 of a tubular bottle i6 so as to provide a smaller or lreducing neck 49 for a smaller nipple 5|. In the neck 49 of this cap 48 the same flow control is used as heretofore described. This cap 48 is shown to illustrate also another feature which can be used in connection with all the arrangements herein described. This feature is the exterior indication of the flow adjustment. A mark 52 is provided on the neck of the bottle i 6 or The open end of this dome-like cap 59 is interiorly on the neck adjacent to a disc carrying cap 48. On the flange of the cap 48 are provided a series of markings 53 which are graduated in accordance with the relative position of the opening of the upper disc on the lower disc in the regulating device heretofore described. For instance, the marking and graduation 1 indicates alignment for the smallest opening, and the subsequent markings indicate alignments for correspondingly larger openings. By such exterior markings the passage can be regulated byturning the cap or the nipple so that the desired indicia on the flange are brought into alignment with the fixed markking 52 on the neck and thus the flow can be controlled without the necessity of taking the device apart or in'some instances even without removing the nipple.

In Fig. 10 I show a modified form wherein the superimposed discs are formed as the closed ends of substantially conical or dome-like members extended inside the nipple. In this form the inner cone 54 is open at the bottom and has its flange 36 resting on the usual resiliently compressible gasket 33 as heretofore described. The closed end 51 of this cone 64 is fiat so as to form a disc with apertures 58 therethrough. A dome-like cap 59 nts inside a so-called breast nipple 6I so as to reenforce the same and prevent its collapsing.

threaded at 62 so that it can be screwed on the top of a neck of ka bottle 'or on any neck for the nipple. The apex of this dome-like cap 59 is ilat so as to form a control disc 63 which is provided with an opening 64 for regulating the ow through the openings 58 of the lower disc 51 in the manner heretofore described. In this form an adjustment of the ow can be accomplished by turning the nipple and its dome-like lining cap 59 relatively to the inner stationary cone 54.

In the form shown in Fig. ll the control arrangement is 'extended to the inside of the mouthpieceof the nipple. It is advisable in this structure to have the discs slightly compressible or flexible. The upper disc 66 is held in a suitable annular slot B1 in the passage of the mouthpiece 68 of the nipple so that it turns with the nipple. A stationary disc 69 is held against the lower side of the upper disc 68 by means of a bar 1|, which latter in turn extends from a perforated disc 12 resting on a suitable resiliently compressible gasket 13. In this form, in order to hold the base of the lower disc 89, I provide a cap 14 which, when screwed on the bottle neck, forces the perforated disc 12 on the gasket 13 and holds it and the disc 469 therewith in place. The nipple in this case is attached over the cap 14 and thecontrol is accomplished and regulated by the turning of the nipple or the cap under it.

- The nipple is tted over the cap in such a manner that the upper disc 66 is firmly held by the tension of the resilient nipple en thelower disc 69 as the nipple and cap are turned to change the relative position of discs 66 and 89. As in other forms shown, the cap may be turned for adjustment without danger of leakage, since the resiliently compressible gasket permits considerable up or down movement of the screw cap without losing sealing contact and without losing the necessary pressure against the discs. If desired the nipple may be used Without the control disc 69 and its supporting base. In that case the screw cap is screwed down until it contacts, the gasket, and a disc with suitable hole or holes is inserted in place of the disc 68. A single disc control would make it possible to have a doctor prescribe certain discs for proper feeding which could be inserted. This would leave the control in the hands of the doctor. Such single discs can also be used with all other controls herein shown. Discs being of non-swelling material would permit finerholes, which would not change because of swelling or deterioration.

In the form shown in Fig. l2 the nipple 11 has a tubular comparatively stiff base 18 which is threadedly or .otherwise attached in the usual gasket 33 in the neck of a bottle I6 in the manner heretofore described. In' this form the nipple 81 is provided with a flexible thicker b ase portion 88. The tubular portion of the nipple 81 extends through a hole 89 of a cap 9| which latter is threadedly secured to the outside of the neck of the bottle I6. .The top 92 of the cap 9| is conical and is so shaped that it presses the thickened base portion 88 of the nipple 81 inwardly when the cap 9| is tightened or screwed upon the neck of the bottle I6, and allows said base portion 88 of the nipple 81 to expand when the cap 9| is unscrewed from the bottle. The apertures 93 in the disc 88 are arranged in radially spaced circumferential series toward the periphery of the disc 88 so that as the nipple base/8l is partly collapsed onto the disc 86 by the cap top 92 it covers these apertures 93 in accordance with the relative positions of the cap top 92. In this form the flow to the nipple is controlled, therefore, by positioning the cap so as to exert greater or lighter pressure by the cap top 92 upon the lower portion 88 of the nipple 81, and thereby to hold said nipple compressed to a desired degree.

In all the forms herein described and especially in connection with the double neck structure irst described, it is advisable that the nursing bottle be held in a predetermined position for feeding so as to prevent. spilling of iiuid out through the vent neck. Both the-efficiency of the feeding as well as the proper holding of the nursing bottle is facilitated by shaping the mouthpiece of the nipple in an oval or elongated form as shown in 94 in Fig. 15. The shape of this nipple is such that the corners of it fit the corners of the mouth of the infant and regulate the sucking in of the air by the infant. This also facilitates the holding of the nursing bottle at that desired angie. The nipple is placed upon one of the necks of such double neck or upon the neckof the bottle so that the elongation of this nipple 94 is on an axis substantially at right anbles to the portion of the nursing bottle which is to be at the top during the feeding.

It is to be further noted that nipples may be perforated in the mouth piece to provide additional suction holes, as shown in Fig. 3. Such suction holes serve to prevent collapsing by equalizing the suction force exerted by the infant on the inside of the nipple with the suction force inside of the infants mouth. Thus very soft nipple tips may be used as long as the portion of the nipple on which the lips rest and seal themselves is firm enough to withstand suction without collapsing. In connection with the devices herein described more or larger openings and slots can be provided on the mouth piece of the nipples, than in previous nipples, because the control of the flow is accomplished by regulation independent of the cavity or openings of the nipple. Such larger openings on the mouth piece of the nipple will obviate a common disadvantage of previous nipples namely the closing of the nipples on account of swelling or the like action of the material of the nipple. In nursing with applicants device the rate of speed of feeding is substantially independent of the size of the opening in 'the mouth piece of the nipple and may be controlled accurately by holes in the discs which are not subject to change by swelling.

In operation the adaptor cap or nipple and the regulator device can be easily and quickly removed and cleaned. The device allows greater facility .in sterilization and cleaning than devices heretofore used. When the bottle is filled with the desired formula or liquid than either the adaptor cap or the regulator, as the case may be, is put in place as heretofore described and the vent holes are adjusted to the desired degref` of air intake. If a regulator is used also in the nipple then the same is also adjusted to the desired degree of passage and the bottle is ready for use. Thereis no air bubbling though the liquid because the air pressure is provided above the liquid level in the bottle when in feeding position. In case of clogging of the nipple or of the passages when the double neck structure is used, the same can be cleared promptly by interchanging the feeding to the-other neck which theretofore was used as a vent. I'he use of the hrst clogged nipple as a vent accomplishes the self-cleaning of the clogged apertures therein. The device can'be made in the form of an attachnient to standard nursing bottles or containers, although it is preferable to use'a tubular bottle open at. both ends to further 'facilitate cleaning and sterilization. The arrangement and size of the holes is such that they are self-cleaning, and this is so especially in the typer shown in Fig. 4. The manipulation of the regulator is very simple. It does not require any special tools or ttings; it is of unitary character; it can be easily assembled, handled, and adjusted and used by the average layman.

The device can be completely closed so as to or one or the other neck oi the double neck type arrangement may be closed when required, thus aording greater ilexibility of the regulation as to the mode and rate of feeding.
