Definitions

  • the present invention relates to a re-useable nursing bottle and teat assembly for feeding infants which suckle, including humans and animals. More particularly the invention relates to a nursing teat and teat and bottle assembly in which the flow of contents from the bottle is responsive to the demands of the infant and which, preferably, can be easily adjusted to any preset level to suit any infant.
  • the liquid withdrawn from the bottle by an infant sucking is not replaced by air at a rate which correlates to the rate demanded by the infant.
  • the demand will vary from infant to infant and for any one infant may also vary from one feed to the next or from time to time during a single feed.
  • Such a mis-match between the rate of outflow of liquid and inflow of air can produce a large variation in the vacuum produced in the bottle.
  • the infant will need to release the teat to allow air to enter the bottle through the exit hole or holes of the teat before the infant can withdraw more liquid.
  • liquid outflow from the bottle may occur solely due to the force of gravity, which can lead to a possible choking effect when the infant receives liquid unexpectedly when suckling is temporarily stopped.
  • bottles still suffer a number of disadvantages. If the bottle is inverted or shaken during use, the contents of the bottle can leak out through the air passages. Further, shaking the bottle can also lead to the narrow passages becoming blocked, resulting in teat collapse. In addition, the narrow range of adjustment of the aperture size of the air passages may not be sufficient to accommodate the rate of feed demanded by the infant.
  • a valve and more particularly, a flap valve
  • the flap valve which is normally closed to prevent leakage through the air passages, is formed by a resilient, annular skirt depending from the lower face of the flange.
  • the diameter of the annulus formed by the edge of the resilient skirt is less than the internal diameter of the bottle neck so as to enable it to be inserted into the neck.
  • the flap valve is opened by deforming inwardly away from the inner side wall of the bottle as the pressure in the bottle is reduced by an infant sucking the teat.
  • the positioning of the flap valve against the inner wall of the bottle requires that one or more air passages be provided between the flange of the teat and the rim of the bottle mouth.
  • the air passages are formed by ribs or grooves on the lower face of the flange or on the rim of the bottle neck.
  • a means for regulating the rate of air flowing into a bottle in which a flap valve arrangement is utilised may be by tightening or untightening the cap so as to vary the force applied and thus adjust the aperture of the air passages.
  • U.S. 2,736,446 discloses a device for feeding infants which includes a bottle, a teat, and a retainer cap which secures the teat to the bottle.
  • the teat has a flange that can be seated on the bottle neck and a skirt which can extend into the bottle to contact an inner surface of the bottle.
  • the flange on the teat is provided with an air vent passage in the form of a groove which permits a free inflow of air into the bottle interior through cooperating cap and bottle threads.
  • the skirt of the teat includes a flexible skirt edge which can contact the inner surface of the bottle.
  • the flange of the teat seated on the bottle neck is compressed which in turn causes the flexible skirt to move radially outwards to firmly contact the interior surface of the bottle and thus change the rate of air flow into the bottle via the groove.
  • GB 987907 discloses a device for feeding an infant comprising a feeding bottle, a cap closure and a teat which is secured to the rim of the bottle by the cap closure.
  • the teat includes a flange which is provided with a groove in a surface of the flange.
  • the groove leads to a flap valve which is of a circular configuration and fits inside the rim of the bottle.
  • the pressure exerted by the flap valve on the interior side wall of the bottle can be decreased by releasing the pressure exerted by the cap closure on the flange such that the flap valve is distorted and displaced away from the interior side wall of the bottle.
  • the groove on the teat provides an air inlet such that when a partial vacuum is created within the feeding bottle during use by the infant, the flap valve can be slightly displaced from the side wall of the bottle to allow the ingress of air into the feeding bottle. Once the air pressure within the bottle is equal with the exterior of the bottle the flap valve is able to again be positioned against the interior side wall of the bottle.
  • U.S. 4,613,050 discloses a teat which is securely fastened to a bottle by a screw threaded cap.
  • the teat includes an inner depending lip and an annular flange which includes radial grooves to permit the inlet of air to the bottle.
  • the downward pressure exerted on the teat causes the inner depending lip to be turned radially outwardly to engage and seal with the interior wall of the bottle. If the pressure in the bottle falls due to the infant sucking out through the teat, the lip is deformed inwardly away from the inside of the bottle neck such that air can enter the bottle through the radial grooves in the flange of the teat.
  • the flap valve seals against the bottle under an indirect force exerted by the cap on the valve.
  • an axial force is exerted by the cap on the flange of the teat so as to stretch an annular area of the flange which has a radius which is smaller than the radius of the bottle mouth, thereby resulting in a turning moment being generated in the annular skirt.
  • This causes the skirt to deform outwardly in a radial direction; that is, at right angles to the axial tightening force, and to seal against the vertical inner side wall of the bottle.
  • the present invention therefore seeks to overcome or reduce some or all of the disadvantages outlined above by providing an improved flap valve arrangement in a teat and bottle assembly, or a teat for use in the assembly.
  • One object of the present invention is to provide a nursing bottle and teat assembly utilizing a flap valve which seals reliably in the absence of an infant sucking on the teat.
  • Another object of the invention is to provide a nursing bottle and teat assembly utilizing a flap valve wherein the minimum vacuum pressure at which the flap valve opens can be varied so as to accord with the demands of any infant.
  • an assembly comprising a nursing bottle, a teat, said teat having a flange with a sealing surface, and a retaining cap for releasably retaining the teat to the bottle; characterised in that the retaining cap moves in a direction to act on the flange to press the sealing surface or edge of an annular skirt, depending from the lower surface of the flange into sealing engagement with a wall of the nursing bottle in a direction substantially parallel to the direction of movement of the retaining cap, to form a flap valve.
  • the flange of the teat has a resilient skirt dependent therefrom which provides the sealing surface of the flap valve.
  • the sealing surface of the flap valve can be progressively and directly forced against the wall or mouth of the nursing bottle. This advantageously provides a degree of control or regulation over the vacuum pressure required to open the flap valve. This ability to regulate the vacuum required to open the flap valve allows infants of differing physical developments to feed in comfort.
  • the flange of the teat being integral with and of the same material as the teat, is able to flex under force to enable a variable force to be applied between the sealing surface of the flap valve and the sealing surface of the wall or mouth of the bottle.
  • the flange of the teat has a resilient skirt dependent therefrom which provides the sealing surface of the flap valve.
  • the stiffness of the flap valve is predetermined in accordance with the physical development of an infant so as to determine the vacuum pressure required to open the flap valve.
  • the present invention also provides, in another preferred form, a teat and bottle combination, said teat and bottle combination including a cap for retaining the teat on the bottle, said teat having a flange forming a flap valve with a wall or mouth of the bottle wherein the sealing surface of the flap valve is directly pressed against the wall or mouth of the nursing bottle by direct force applied by the retaining cap.
  • the present invention further provides a nursing teat adapted for attachment to a nursing bottle, said bottle having a mouth with a rim and having a shoulder which is inclined relative to the wall of the bottle, said attachment of said teat to said bottle being by means of an annular cap, said teat including an annular flange and a flap valve which comprises an annular skirt depending from the lower face of the flange in which:
  • the present invention therefore additionally provides a nursing bottle and teat combination including (i) a bottle, (ii) a teat with an annular flange, (iii) an annular cap which is connected to the bottle to fasten the teat in position by holding the flange between the rim of the bottle mouth and the cap, (iv) a flap valve comprising an annular skirt depending from the lower face of the flange with an annular flat surface thereon, and (v) a shoulder on the bottle which is inclined relative to the side wall of the bottle, and wherein (a) the flap valve normally forms a seal against the shoulder or mouth of the bottle by the direct, adjustable axial force applied to the skirt by the cap; (b) reduced pressure in the bottle as a result of suckling of the nursing infant causes the flap valve to open by resiliently deforming the skirt away from the shoulder or mouth; and (c) the axial force applied to the skirt by the cap is adjustable thus varying the pressure at which the flap valve opens.
  • the shoulder on the bottle is a surface which is external or internal to the bottle.
  • the shoulder may be perpendicular to the sides of the bottle but is preferably inclined at an angle to the side wall of the bottle.
  • the skirt on the annular flange is shaped to suit contact with the shoulder or mouth when the valve is closed.
  • the skirt is adapted to provide a large contact area with the sealing surface of the wall or mouth of the bottle thereby improving the sealing characteristics and regulation of the vacuum pressure required to open the valve.
  • the retaining cap used to hold the teat in place on the bottle has a perforated annular end to go over the teat, and a generally cylindrical skirt dependent from the lower face of the end.
  • any suitable means may be used to couple the cap to the bottle, including a bayonet or screw threaded coupling.
  • the bayonet coupling is particularly preferred if the means of adjusting the required vacuum pressure to open the flap valve is to be by varying the axial force applied to the skirt.
  • the bayonet coupling has a number of fastening pins, each of which slides in a groove having an upper wall which inclines towards the bottom of the bottle so as to increase the force on the teat skirt as the cap is tightened.
  • the fastening pins may be located on the inside surface of the skirt of the cap and the corresponding groove or grooves located on the outer surface of the side wall of the bottle, or vice versa.
  • a "tamper-proof" feature of the bayonet coupling may be provided, in the form of a stopper at the upper end of each groove, so that at the end of the travel of the cap as it is unscrewed the cap requires an extra downwards (i.e. towards the bottle) force to enable it to be removed for cleaning or filling. This prevents accidental removal of the cap, with resultant spillage.
  • the bottle assembly may include indicating means, such as co-operating projections and indentations on the inside surface of cap skirt and outer surface of bottle, to facilitate adjustment of the pressure at which the flap valve opens to suit the particular infant's needs.
  • an annular slip ring is located between the lower face of the cap and the upper face of the flange on the teat to prevent the flange and/or skirt from buckling as the cap is tightened or untightened and thereby reducing the effectiveness of the flap valve.
  • the slip ring may be made from, or coated with, any low friction material.
  • a low friction plastics such as teflon, is used.
  • the bottle and teat assembly preferably includes a cover to protect the teat when not in use and to avoid the necessity of inverting the teat from a carrying or non-use position with the teat projecting into the bottle to an in-use position where the teat projects ready for use.
  • the teat is preferably always carried in the in-use position and is protected by a cover which helps to keep the teat clean and helps to prevent leakage from the teat and bottle assembly during transport when containing liquid.
  • the cover preferably fits snugly over the teat and includes in its upper end a dimple or projection which, when fitted, presses against the top of the teat and seal the teat holes to prevent or reduce leakage of liquid.
  • the teat cover also preferably includes a flange which, when the cover is fitted, presses on a secondary flange of the teat, securely holding it between the cover and the cap, thereby forming a secondary seal to contain any liquid that may have leaked through the teat holes.
  • the teat cover is preferably coupled to the bottle by a "tamper-proof" and tight-fit coupling.
  • a novel design of closure system is provided wherein the teat cover and the teat retaining cap or bottle are adapted to be fitted together with a snap fit action and to be separated by a turn and pull action.
  • the teat cover may be coupled to the bottle by a conventional snap fit arrangement or by a screw or bayonet coupling.
  • the nursing bottle assemblies shown in Figures 1 to 6 generally comprise bottle 10, teat 12, slip ring 13, retaining cap 14 and teat cover 15.
  • the upper end 11 of the bottle 10 (part shown) has an annular shoulder 16 which is inclined relative to the cylindrical wall of the bottle 10.
  • the teat 12 has a lower annular flange 18.
  • An annular skirt 19 depends from the lower face of the flange 18. The lower end of the skirt tapers to form a flat annular face 20.
  • the skirt 19 abuts the shoulder 16 near the mouth 22 of the bottle 10 and the edge 21 of the skirt 19 engages the shoulder 16 on the bottle 10 forming a flap valve seal which is broken when an infant sucks on the teat 12 of the bottle 10 and causes the edge 21 of the skirt 19 to deform away from the shoulder permitting air to enter the bottle 10 and in consequence, permit liquid (not shown) to be drawn from the bottle 10 by an infant.
  • the cap 14 is generally cylindrical, has a central hole 23 in its upper end 24 which enables the cap to pass over the teat 12 and to hold the teat in place.
  • the top 24 of the cap 14 forces the skirt 19 of the flange 18 against the shoulder 16 of the bottle 10.
  • Opposed projections 25 are located on the inner surface of the wall of the cap 14 configured to slide in grooves 17 on the outer surface of the wall of the bottle to couple the cap to the bottle.
  • the upper wall of each groove inclines towards the bottom of the bottle and as the cap is tightened the projections follow the slope of the groove, increasing the pressure on the face 20 of the skirt and increasing the surface area of the face 20 in contact with the shoulder 16, with the result that the flap valve requires an increased pressure to be exerted on the teat by the infant to open.
  • a series of cap projections 27 are formed on the inside wall of the cap and co-operate with a series of wall projections 26 around the circumference of the outside of the wall of the bottle.
  • the opposed or interfering cap projections and wall projections are resiliently deformable, enabling the projections on the cap to push or "click" past the wall projections as the cap is tightened or untightened.
  • the number of projections traversed as the cap is tightened provides a visual, tactile and/or audible indication of the degree of force exerted on the flap valve.
  • the nursing bottle and teat assembly can be quickly adjusted to the correct force by re-aligning the projections to the position determined as appropriate to the age or physical development or the demand (at any time) of the infant.
  • the bayonet fitting of the cap allows for a "tamper proof" fitting of the cap to the bottle.
  • the adjustment of the cap to permit variation in the flow of the liquid from the bottle does not result in accidental removal of the cap (with resultant spillage).
  • the cap requires extra downwards force (i.e. towards the bottle) to enable the cap to be removed for cleaning or filling.
  • the slip ring has a central hole which passes over the teat.
  • the slip ring is of a similar diameter to the flange on the teat and provides a low friction upper surface which slides against the cap as the cap is fastened or unfastened so that the teat is not twisted by the rotary motion of the cap. It should be noted that, if the materials of the cap 14 and the teat 12 are such that there is very little friction between the cap and the teat when they are in direct contact, with the consequence that the teat is not twisted by the rotary motion of the cap without using the slip ring, then the slip ring is not required.
  • the teat has a mouthpiece 28 with a perforated end surface.
  • the inside end face 29 of teat cover 15 is flattened or convex or includes a projection so that when the teat cover 15 is in place the mouthpiece of the teat is sealed against the inside end face of the teat cover.
  • the teat cover 15 is held on the cap by means of a snap fit connection between one or more projections 30 on the inside surface of teat cover 15 and one or more cooperating indentations 31 on the outside surface of the cap.
  • the teat has an additional or secondary flange 33 which forms a secondary liquid seal with the seal bead 32 on the inside of the teat cover at a position overlying the secondary flange when the cover is snap fitted onto the cap of the teat and bottle assembly.
  • the secondary flange prevents the teat from being pulled towards the bottle 10 by the vacuum developed in the bottle during feeding.
  • the flap valve is shown in a substantially completely closed and inoperative position, as a result of the cap being turned until the opposed projections 25 on the cap engage the end of their respective grooves 17 on the outer surface of the bottle wall. In this position there is maximum surface area of contact and maximum contact force between the flap valve and the shoulder, thus preventing any possibility of leakage of the bottle contents through the flap valve when the bottle is transported.
  • annular skirt 19 depending from the lower face of the flange 18 tapers at its lower end to form a thin annular edge 21 which, when the assembly is assembled, abuts the outer surface of the shoulder 16 near the mouth 22 of the bottle 10 forming the flap valve seal.
  • the secondary flange 33 on the teat fits snugly in a groove 36 in the upper end 24 of the cap when the assembly is assembled.
  • the nursing bottle and teat assembly depicted in Figure 4 comprises generally similar arrangement to the bottle assembly depicted in Figure 3. However, in this embodiment the edge 21 of the skirt 19 forms a flap valve against an inner shoulder 44 on the bottle 10.
  • Figures 5 and 6 illustrate further embodiments of the present invention in which the cap 14 is fastened to the bottle 10 by means of opposed threads 45, 46 on the bottle and cap respectively.
  • the flange 18 is supported on a perforated neck 48, which has perforations 47 in numbers and/or sizes sufficient to ensure that the flow of air through the neck is not impeded.
  • the teat must be replaced by another teat of similar construction but having a different stiffness in the skirt.
  • a series of teats with different skirt stiffness can be made available to be used in the bottle assembly, and the consumer needs to buy only the teat that suits the infant at any particular stage of the infant's development.
  • the outer surface 51 of the cylindrical wall of the teat retaining cap 14 is provided with guide means in the form of a pair of projections 53a, 53b which are spaced so as to define a gap 58 therebetween.
  • the projections 53a, 53b are located proximate the upper end 24 of retaining cap. As is best illustrated in Figure 8, a series of pairs of projections 53a, 53b are located around the outer circumference of the cylindrical wall of the retaining cap.
  • the teat cover 15 is provided with a corresponding guide means on its inner surface 54.
  • the guide means comprises a projection 55 located in the upper portion of the inside of the teat cover away from the open end 56 of the cover.
  • the projection 55 extends in an axial direction down from the inside surface of the upper wall 57 of the cover.
  • a series of projections 55 are located around the inner circumference of the cover 15.
  • the projection 55 on the inner surface of the teat cover passes neatly through the gap 58 defined by the projections 53a, 53b on the outer wall of the retaining cap.
  • Cooperating locking means in the form of projections or lugs 60, 61 are provided on the outer surface of the retaining cap and the inner surface of the teat cover, respectively.
  • the locking lug 61 is provided on the inside surface of the teat cover at a location proximate the open end 56 of the teat cover.
  • the locking lug 60 is provided on the outside surface of the retaining cap at a location which will result in the two locking lugs 60, 61 cooperating to restrain the cap when the cap is fully fitted.
  • the projection 55 on the inside surface of the teat cover 15 is brought into alignment with the gap 58 between the two projections 53a, 53b on the outer surface of the retaining cap 14.
  • the locking lug 61 on the teat cover and locking lug 60 on the retaining cap are also in proximity to each other. In this position the locking lugs 60, 61 are not in direct alignment but are slightly offset as illustrated in Figure 10a.
  • the fastening arrangement for the teat cover on the retaining cap may comprise a plurality of such locking mechanisms spaced around the circumference of the opening of the retaining cap.
  • the relative location of the guide means and the locking means on both the teat cover and the retaining cap are inverted. That is, the locking means is located at the upper end of both the teat cover and the retaining cap, whilst the guide means are located at the lower (open) end of the teat cover and at a corresponding position on the retaining cap.
