656,240, filed Jul. 26, 1967 and now abandoned.

f p This invention relates to feeding devices especially for infants and is directed particularly to a feeder unit and combination of the unit and a container which can be used, selectively,

,feed soft or pureed foods, such as meats and vegetables, at a very early age. Inasmuch as in young infants the normal reflex is to suck food presented to the mouth, spoon-feeding is difficult and generally impracticable and inadequate. It is accordingly one object of this invention to provide a feeder unit for flowable materials having a novel air-admitting valve structure connectable at one end to a nipple, and at the other end, selectively, to a rigid or semirigid or collapsible container, either of which could be reuseablev or supplied as a commercially prepared disposable. baby food container, as desired or required.

It is another object to provide a feeder unit for acontainer which includes a novel air valve structure operative to permit the entrance of air to relieve any vacuum formed in the container during feeding.

It is still another object to provide a feeder unit and container in combination with the unit which is of the character described wherein the air valve is comprised of few and simple parts which can readily be disassembled for cleaning and sterilizing, whether by the special orterminal method, and

which parts are smooth and devoid of sharp comers or crevices in which food particles or milk solids can be entrapped, to insure easy and thorough cleaning with little effort after each use.

Yet another object is to provide a bottle feeder system of the above nature which will be inexpensive to manufacture, low in cost, foolproof in operation and durable in use.

It is also an object of this invention to provide an improved feeder unit and package for said unit. I

It is an additional object of this invention to provide an improved feeder unit and screen means to act as a sieve or strainer to insureuniform consistency of flowable materials being fed to a baby from a container.

It is an additional object of this invention to provide an improved feeder unit which provides a collapsible bellows type liner for a bottle or container. 7

Referring now in detail to FIGS. 1 through 7 of the drawings, the numeral 10 in FIGS. 1 and 7 designates a feeder unit embodying the invention in combination with a container, the combination being comprised, generally, of a bottle or container member 11, a nipple support collar and valve seat member 12, a nipple 13, a bottle cap member 14 and a nipple hood or support cover member 15.

The container member or bottle member 11 may be cylindrical in form, preferably molded of suitable nontoxic tough synthetic plastic material, the open end or mouth being provided with a threaded neck as indicated at 16, for receiving the cap member 14, as is hereinafter described.

The nipple support collar member 12, (see FIGS. 1, 2, 3, and 7), which is also preferably integrally molded of a tough synthetic plastic, is companionately shaped to mate with the other parts of the unit and container as isthe circular form shown in the drawings and formed with a peripheral flange portion of lip 17 connected to an axially-extending inner wall portion 18, which may be curvilinear in elevation as seen in FIG. 2, and defining, at its inner edge,.a central circular opening 19. I

The axially-extending inner wall portion 18 of the nipple support collar 12 is formed along its inner and upper wall surface, (as seen in FIG. 2), extending from the peripheral flange portion 17 thereof, with (a) a wall surface portion 20, which may be concavely curved defining a partial floor for a flutter chamber to be described, (b) a concentric, relatively short cylindrical wall portion 21, (c) a convergent, wall surface portion 22, shown as frustoconical in FIG. 2, and (d) a short cylindrical wall portion 22a may be provided, the outer edge of which terminates at the central circular opening or passageway 19, found in the various embodiments. The diameter of the nipple collar member 12 and the width of the peripheral flange portion 17 are such as to provide a shoulder or lower lip surface 23 at the underside of said flange portion 17 that seats against the annular upper or leading edge of the container 11 for securement thereagainst of said collar member by the bottle cap member 14, as is hereinbelow described. The flutter chamber is provided with a port leading to the interior of the container as by providing a pair of diametrically-opposed, arcuate' through openings 24 in the concave wall surface portion 20 of the nipple support collar member 12 for the passage of air, for the purpose hereinafter described.

The nipple member 13 is of molded rubbery material such as a suitable natural or synthetic rubber, is hollow, symmetrical in shape about its longitudinal axis, and formed with the usual protuberance and duct in the tip or nipple end 25 and a support or base portion, generally indicated at 26, of increased diameter for. hooked up engagement of the base and the inner surface of the cap 14 with the protuberance extending through the main feed flow passageway of the unit as will be described and is apparent in the drawings. The nipple support base portion 26 is configured to mate with the seat surface of the seat member and in the embodiment of FIG. 7, it is formed with an outer periphery with a central cylindrical wall portion 27, the lower end of which merges with an inwardlyinclined annular, 'beveled wall portion 28 which may terminate in a short, cylindrical wall portion 29 at the outer end. Flap means are provided, preferably in the following manner. The upper end of the central cylindrical wall portion 27 of the nipple support base 26, comprises a flap means and extends into an outwardly inclined, annular upper end portion 30 which may terminate in a rounded peripheral bead 31 extending into a slightly depressed or recessed horizontal annular upper end wall portion 32 lying in a plane substantially perpendicular to the longitudinal axis of rotation of the nipple member 13. As illustrated in FIG. 1, the size and exterior shape of the lower end of the nipple support base 26 of the nipple member 13 isv such as to fit in embracing relationship with respect to the nipple support collar member 12 with the inwardly-inclined beveled wall portion 28 of said nipple support base in seating engagement against the mating frustoconical wall surface portion 22 of said nipple support collar member. It is further to be noted that when the nipple member 13 is in such seating engagement with respect to the nipple support collar member 12, the upper end wall portion 32 of the nipple support base member 26 will lie substantially in a common plane with that of the upper or outer surface of the peripheral flange portion 17 of the nipple support collar member when the device is assemble as illustrated in FIG. 1.

The cap member 14, which also is preferably molded of a tough synthetic plastic material, is fonned with an internallythreaded skirt portion 33 threadable on the externallythreaded upper end of the container member 11, and a flat end wall portion 34 provided with a central circular opening 35 of such diameter as to snugly admit the protuberance or nipple end portion 25 of the nipple member 13 with the upper end wall portion 32 of the nipple support base portion 26 of said nipple member in seating engagement against the inner surface of the flat end wall portion when the bottle feeder is assembled as illustrated in FIG. 1 and .in sealing relation of vent opening 36. It will be noted that when so assembled the peripheral bead 31 of the nipple support base 26 will be deflected outwardly, it being of comparatively soft rubber and therefor substantially more resilient that the nipple support collar member 12 and the bottle cap member 14 between which it is normally clamped by compressive forces when the device is in the assembled relation illustrated in FIG. 1 and indicated in FIG. 17 thereby normally insuring a tight and effective seal of the flap means against the underside of the bottle cap member 14. As illustrated in FIGS. 1, 6 and 7, the flat end wall portion 34 of the'bottle cap member 14 is formed with vent means 36 composed of a pair of diametrically-opposed arcuate openings 36 spaced slightly outwardly of the central opening 35 of said end wall portion. As illustrated in FIG. 1, the arcuate openings 36 are so arranged as to lie over portions of the flat end wall portion 32 of the nipple member 13 when the device is assembled for use, as is indicated in FIG. 17 illustrating the assembly and in FIG. 18, illustrating the self-venting operation, which will be explained hereinafter.

gl-lood means are provided for protectively covering the nipple member 13 when assembled to the feeder unit prior to its use in feeding. To this end, the outer surface of the flat end wall portion 34 of the bottle cap member 14 is integrally formed with clip means of an outwardly-extending, concentric circular bead portion 37 defining in its outer periphery a shallow arcuate recess 38 adapted to receive, in releaseable interlocking engagement, the inwardly-directed lip portion 39 formed at the outer end of the cover member of the hood means. The nipple cover member 15, which is also preferably molded of a tough synthetic plastic material, may be frustoconical in shape, as illustrated, and closed at its upper end with an integrally formed end wall portion 40.

It will be helpful in considering now'the operation of the feeding unit to refer to FIG. 1 and also to FIGS. 17 and 18. First, with reference to FIG. 17, assembly of the feeder unit through a threaded container neck will be described, J

As the leading edge of the end 16- of 5 the container is' threadably advanced into the skirt portion -33'toward the inner surface of the end wall of thefda'p member, the surface of the valve seat compresses the nippl'ej'base and causes a force component which results in a normal'moment indicated by arrowed lines and urging the flap rr'iean's toward the normal position of sealing engagement over th''veiit means 36 of the cap 14. As seen in FIG. 1, a comparatively rigid container member 11 is used for the feeding of liquids, it will be'understood, on reference to FIG. 18, that when a vacuum develops within the container during feeding, as material is removed through the nipple duct, the relatively greater ambient atmospheric pressure will exert sufficient force to cause a moment M against the end wall portion 32 of the resilient nipple member 13, through the vent means of the cap, arcuate openings 36, to deflect the flutter valve which is shown extending from the nipple base in the direction of the interior of the container member and in the flutter chamber 41. Such deflection of the nipple base permits air to enter the annular flutter chamber 41 between the nipple base and the interior of the nipple support collar and valve seat 12 to pass through ports or vents in the flutter chamber as through the arcuate openings 24 and thereby relieve the vacuum in the container.

FIG. 8 illustrates an alternative food container 42 for feeding soft, strained or pureed foods, which preferably is integrally molded of a tough, nontoxic, synthetic plastic material to provide a substantially tubular body portion 43 having at one end a relatively rigid tubular neck portion 44, screwthreaded at the outside to receive the feeder unit comprised of the cap member and its associated valve and nipple structure as described above in connection with the embodiment of FIG. 1. The body portion 43 of the container portion 42 is of thin enough wall section to be easily compressed for moving foods of heavierconsistency, paste or puree, foods for example, in the direction of the nipple form time to time, as may be necessary to overcome sticking to the inside container walls and consequent waste of food. Vacuum relief, when required, is effected as described above in connection with the description of operation in the embodiment illustrated in FIG. 1. The food container 42 may be suspended within a rigid bottle as a liner, which,,as-indicated in FIG. 15, may, alternatively, comprise a collapsible bellows of thin walled tubular construction or a Sylphon.

Referring now to the alternative embodiments of this application, like reference characters and nomenclature will be used to designate like or corresponding parts and where suitable to facilitate a ready understanding, prime designations shall be employed.

As seen in FIG. 9, stop means 50 may be provided on the bottle end 16 of the container to limit axial movement of the skirt portion relative to the end wall of the cap 14. The surface of the cap may also be provided with grip surfaces or knurling as at 55 to aid in tightening or loosening the cap from a container. The partial floor of the flutter chamber 41 defined by the surface 20' of the nipple support member or valve seat 12 is generally transversely arranged while the ports for venting 24' are parallel to the axial centerline of the unit and located in the floor of the flutter chamber. A slight draft angle not shown is to be found in the preferred embodiment to facilitate inexpensive manufacture of the valve seat by molding. The cylindrical wall portion 29 of the nipple base portion 26 is omitted in this embodiment as is the corresponding cylindrical wall portion 22a. In this embodiment the cylindrical wall portion 21 is of a diameter slightly less than the corresponding mating surface 27 of the nipple base 26 to provide means to maintain the unit composed of the cap 14, nipple 13 and seat member 12 in an assembly as a unit. Alternatively, clip means composed of interengaging male and female portions or projections on the confronting surfaces or faces of the cap and valve seat member may be provided as at 57. Also, the surface 32 of the nipple may be flat as at 32 i.e.', without the recessed face 32 as seen in FIG. 4 in relation of FIG. 11. Additionally, sieve means or a screen element 59 may be secured across the passageway of the unit, as in the spanning relation of the opening 19 shown in FIG. 12. This elementmay be of integral construction, see FIG. 12, or be provided for optional use in a carrier 61 with a screen element 63, see FIG. '13, the carrier and end 22 of the member 12 having interengaging ears 65 to hook up in the bite of a yieldable bead 67 about the screen carrier.

In a preferred embodiment the container is provided with a bellows-type liner 71 or Sylphon of thin walled construction lightweight, inexpensive preferably plastic material having a lip 72 from which the liner body 73 depends within the container. The liner isadapted to be suspended with the interior of the container and the cap 14 tightened over the end of the container as described above.

It will be seen that the bellows-type liner is adapted to be compressed when not in use and readily stored in a sterile package, either alone or together with the packaged unit as seen in FIG. 16, which will now be described.

Referring to H6. 16,- the feeder unit is packaged in a hood of flexible plastic material 74 secured to a backing board 75 bya suitable adhesive or by heat sealing so as to prevent the entrance of germs within the receptacle 76 thus fonned, the bellows-type liner described above may be'included as a part of the feeder unit whereby the entire package is adapted to be dropped into a bottle or container with a minimum amount of handling, the bead 77 in the Sylphon being received over a mating annular bead 78 which maybe provided in the outer wall of the flutter chamber 41 see FIG. 9.

It will be noted that the feeder unit of the nipple support collar member, the nipple member and the cap member comprising the vacuum relief mechanism are simple in construction and devoid of sharp edges, crevices or small openings that are likely to trap food particles and thereby become a source of contamination;
