Definitions

  • This invention relates to infants, feeding bottles of the kind comprising a container for liquid, a teat securable onto the container, a detachable teat cover arranged to enclose the teat and a closure which, before use separates the interior of the teat from the interior of the container.
  • an infants feeding bottle as claimed in claim 1 of the Complete Specification of British Pat. application No. 10529/70, Cognate No. 44739/70 is modified in that the outlet opening of the container has an internal projection and the closure means has two axially spaced protrusions which, when the closure member has been displaced from the sealing position, are located at either side of said projection, to limit movement of the closure means within the container, the closure means being shaped such that, when in such displaced position, it permits substantially unrestricted flow of liquid, at least from the container to the teat.
  • FIG. 1 is an enlarged cross sectional view of a feeding bottle in the closed and sealed condition
  • FIG. 2 is another view of the bottle indicating an intermediate stage in preparation of the bottle for use
  • FIG. 3 is a cross-sectional view of the bottle in condition for use, but with an alternative form of closure means and FIGS. 4 and 5 are cross-sectional views on the line c--c in FIG. 3 of two alternative constructions.
  • the infants feeding bottle illustrated is primarily a disposable one, being intended to be used only once, and is therefore made from inexpensive materials such as plastics.
  • The'bottle comprises a container for liquid such as milk or a mixture of milk and other substances.
  • the container has an outlet opening 11, at one end which is surrounded by an external frusto conical surface 12.
  • an annular surface presented to the interior of the container meets the surface 14 to provide an acute angled annular edge 16, for the projection 13.
  • the external frusto conical surface 12, of the container is engaged by a complimentarily shaped flange 17 of a resilient teat 18.
  • the teat l8, moreover, has a bulbous end which is apertured at 19 to provide an outlet.
  • a securing ring 20 surrounds the teat flange l7 and is secured to the container 10 in any convenient manner, thus retaining the teat in sealing engagement with the surface 12, to prevent leakage between the teat and the container.
  • the securing ring 20 has at its narrower end, an annular recess of generally part-circular cross-sectional shape and there is in the teat 18, a further recess 22, which is of similar shape in cross section.
  • This recess 22 is at the junction of the flange 17 with the remainder of the teat l8.
  • Engaging in the recesses 21, and 22 is a head 23 formed integrally on the open end of a cup shaped teat cap 24.
  • the bead 23, is of generally circular crosssectional shape and engages in the two recesses 21 and 22 which thus substantially surround it.
  • the teat cap 24 is made from a rigid material, such as aluminium and protects the teat, not only against damage but also against contamination.
  • the teat 18, is
  • closure means 26 which is engaged within the teat 18.
  • This closure means 26 is in the form of a flanged hollow plug, the interior of which is open to the interior of the bottle 10.
  • a similar plug is used, though the interior is open to the interior of the teat.
  • the plug has generally cylindrical form with three axially spaced flanges 27, 28, and 29.
  • the flange 27 is a shallow cylindrical annulus and when the plug is in the position in FIG. 1, this flange engages the teat 18 in a region adjacent the recess 22 formed in the teat.
  • the teat is effectively trapped between the flange 27 and the bead, 23 of the teat cap 24. This, in itself, provides a seal against the flow of liquid from the interior of the container 10, to the interior of the teat 18.
  • the end of the plug is engaged within the teat in the region 25 at which the cap engages the teat.
  • the interengaging portions of the teat and plug are identified at 30.
  • the flange 28, of the plug 26 is in the form of a flexible skirt of non-circular configuration.
  • FIGS. 4 and 5 indicate two alternative forms of this flange 28. In FIG. 4 it has four equally spaced flats 31, and in FIG. 5, it has four equally spaced rectangular cut outs 32.
  • the third flange 29, of the plug 26, engages the lip 16 of the outlet opening 11 of the container 10.
  • FIG. 2 illustrates the manner in which the teat cap 24, is manipulated to dislodge the closure means plug 26 into the interior of the container 10.
  • the first stage in such dislodgement comprises depressing the cap 24, towards the interior of the container.
  • the flexibility of the teat allows it to be deformed, as shown in FIG. 2, to a position in which the closure meansplug 26, is moved so that its circular flange 28 passes the lip 16 of the projection 13 and because of the flared shape of this flange 28, will not pass back again past the lip 16.
  • the resilience of the teat will now allow the cap and teat together to return to the original position, though the plug will be drawn out of the interior of the teat.
  • the securing ring 20 is made from a resilient material which allows the cap to be forced out of its narrower end without undue damage either to the teat or to the securing ring itself.
  • the feeding bottle is not intended to be used again and for this reason, it is not possible readily to reengage the closure means within the teat nor to reassemble the cap over the teat.
  • the means for attaching the securing ring to the container 10 is not of the kind capable of being re-engaged once it has been removed.
  • the feeding bottle is preferably sterilised after assembly by a heating process and it remains substantially sterile until it is made ready for use.
  • An infants feeding bottle comprising a container for liquid, having an outlet opening surrounded by a seating, an internal projection on the container extending into said outlet opening, a resilient teat with an outlet orifice, the teat having a flange portion engaging the seating, means for securing the flange portion on the container seating to create a seal to contain the liquid in the container, a removable teat cap enclosing the teat, the cap having an internal annular portion engaging a further portion of the teat to create a further seal for the enclosure for the teat, and closure means sealing against communication between the interior of the container and the interior of the teat, said closure means being frictionally engaged in the interior of the teat and being displaceable by manipulation of the teat cap to remove the closure means from its sealing position, such manipulation being carried out with the teat cap covering the teat, and the closure means having two axially spaced protrusions which, when the closure member has been displaced from the sealing position, are located at either side respectively of said projection, to limit movement of the closure means
