Definitions

  • the subject of the invention is a single piece teat-ring, referred to as a "multiflow" teat-ring, for baby bottles intended for feeding infants, as well as a baby bottle comprising such a teat-ring and a protective cap.
  • Baby bottles of the prior art which are most generally made up of a baby bottle body to which a teat, a ring and a cap are attached, have all evolved in such a way as to provide the best solution to the above problems.
  • the latter In terms of the actual teat itself, the latter is generally held on the neck of the baby bottle by means of a ring which fits, screws or “clips” onto said neck, compressing the base of the teat so as to ensure this arrangement remains fluidtight.
  • the ring is generally made of a rigid polymer material whereas the teat itself is more generally made of a polymer material that exhibits elastic properties, notably that is deformable and compressible.
  • the interface or zone of contact between teat and ring is then no longer capable of ensuring the required fluidtightness.
  • drops of milk escape during handling and during actual suckling itself and, on the other hand, air can enter the baby bottle while the infant is suckling, and do so in an uncontrolled way, with the risk of causing the liquid thus administered to be regurgitated unwantedly.
  • the impairment of the polymer materials of which the teat as well as the ring are made also has a negative impact on the ability to maintain cleanliness if not to say sterility or even asepsis that needs to be ensured when feeding the infant.
  • US 2012/0248056 is an illustration of this increasing complexity. That document describes a disposable single-use baby bottle made up of a teat unit resting via its base on a support body or surrounding said support body, itself secured to a fixing part intended to connect said teat unit to the container containing the liquid intended for the infant.
  • said support body and the fixing part are connected in such a way that they cannot be detached from one another without destruction.
  • This type of baby bottle is intended for single use and therefore qualified as "disposable”.
  • Another teat-ring is known from FR 3 035 321 A1 .
  • the invention offers the relevant individuals a baby bottle in which the configuration of the teat is as similar as possible to that of the mother's breast, allowing the stream of nutritional liquid to flow similarly to that of the mother's breast, and substantially limiting any risk of colic.
  • the invention represents a novel and particularly effective solution aimed at eliminating the drawbacks or disadvantages listed above.
  • the subject of the invention is a one-piece teat-ring (1) for a baby bottle (2) intended for feeding infants, having the features of claim 1.
  • Another subject of the invention is a baby bottle (2) intended for feeding infants, made up of a teat-ring (1) as described hereinabove, of a feeding-bottle body (14) and of an ergonomic protective cap (15).
  • the teat-ring according to the invention (see notably fig. 1 ) comprises a flexible top part (3) known as the teat, configured in such a way as to allow the infant to feed, extended by a flexible lower part (4) known as the skirt, dimensioned in such a way as to fit the neck (5) of the baby bottle and a rigid ring (6) chemically secured to the base (7) of said skirt (4).
  • the teat-ring according to the invention is said to be "multi-flow", given the presence of orifices such as (3a, 3b, 3c, etc.) formed in its upper part and acting as milk ducts during suckling - see also Fig. 6 .
  • the ring (6) adheres to the entirety of the external face (9a) of the base (7) of the skirt, ensuring maximum adhesion and securing between said ring and the skirt (4), more specifically the base (7) thereof (see fig. 3 for example).
  • the lower portion of the ring (6) adheres continuously to the circumference of the base (7) of the skirt (4) whereas the upper portion of said ring (6) adheres thereto discontinuously as illustrated in fig. 6 . It has been found that this type of configuration provides the securing of the assembly in a way that is satisfactory while at the same time offering the opportunity to create an original design.
  • One of the preferred embodiments of the invention foresees no point of mechanical catching at the interface between the ring (6) and the base (7) of the skirt (4). This then encourages the best possible adherence between these two components. However, depending on the circumstances, provided that having them does not represent a significant technical obstacle, such mechanical catching points may nevertheless be envisioned.
  • the flexible parts (3) and (4) of the teat-ring (1) form a continuum within which the Shore hardness of the material used varies from a maximum value at the base of said skirt (7) to reach its minimum value at the teat (3).
  • Values of the order of 30 to 40 degrees of Shore hardness are characteristic of the flexibility best suited to the region of the teat (3), so that it is similar to that of the mother's breast.
  • Values of the order of 40 to 50 degrees of Shore hardness are, on the other hand, characteristic of the flexibility given to the skirt (4) of the teat-ring, more particularly in the region of the connection between the base of said skirt (7) and the rigid ring (6).
  • the injection-molding techniques and the polymer materials currently available allow such a continuum to be achieved.
  • the flexibility of the teat (3) can be achieved or accentuated by altering the thickness of the material used for the whole, with a constant degree of Shore hardness, this hardness then being lower, or even substantially lower, than that of the skirt (4).
  • the teat (3) comprises at its base, a region referred to as the junction region formed, for example, of two concave depressions (17a, 17b) of oval, elliptical or similar overall shape, arranged symmetrically with respect to its axis of rotation - see, by way of example, Figs 2a and 2b .
  • the depression or the concavity of the regions (17a, 17b) consists in a reduction of at most 40% of the initial thickness of the region of the skirt concerned, as measured at the center thereof - see Fig. 2a .
  • the periphery of the regions (17a, 17b) may also be shaped in such a way as to break the symmetry of the ellipse and better resemble the impression that the lips of the infant would leave at the junction region - see Figs 2b & 2c.
  • This type of configuration ensures better positioning of the lips of the infant during suckling, thus avoiding or limiting any unwanted ingress of air into the mouth of the infant. This then comes as close as possible to the characteristic configuration of the mother's breast.
  • the terminal part of the teat (3) is preferably rounded, if not perfectly hemispherical (see, for example, Fig. 1 ) and thereby as close as possible to the natural shape of the human teat. It is further provided with several through-holes or orifices or flow ducts (3a, 3b, 3c, etc.) acting as milk ducts during suckling. There are generally 2 to 5 of these, most usually 4, positioned equidistantly on the rounded tip of the teat. In this way the flow of the streams of breastmilk during suckling are mimicked as closely as possible.
  • Fig. 6 is an illustration of this, given solely by way of example.
  • the teat-ring (6) may further comprise one or more mechanical, tactile, audible or visible respectively open or closed position indicators (which are not illustrated).
  • the respectively mechanical or audible position indicator is made up of screw thread portions (10), in other words, of short threads, positioned equidistant from one another on the periphery (8) of the neck (5) of the baby bottle.
  • screw thread portions (10) in other words, of short threads, positioned equidistant from one another on the periphery (8) of the neck (5) of the baby bottle.
  • Such an arrangement means that opening or, respectively, closing, the baby bottle requires only a twist through 90 degrees or less, most generally through between 70 and 90 degrees, whereas the current baby bottles need to be twisted through at least 180 degrees, or even 360 degrees or more in order to obtain the same effect.
  • Figs 7 and 8 give a partial illustration of this.
  • the teat-ring according to the invention comprises at least two devices (13a, 13b) known as "anti-colic” devices, in this instance at least two one-way valves (13a, 13b) or, equally, any other device allowing air to be drawn into the baby bottle, given the depression resulting from suckling.
  • These devices are arranged on the skirt (4) in the spaces (6a, 6b) formed by the ring (6), preferably on the base (7) of said skirt, as illustrated in Figs 4 and 5 .
  • the depression created by suckling deforms the lips of one or the other or both devices (13a, 13b), the deformation allowing air to pass.
  • the lips then start to vibrate and the passage of the air re-equalizes the pressures.
  • the teat-ring according to the invention may of course comprise as many "anti-colic" valves as are required in order to perform the desired function, namely that of equalizing the respective internal and external pressures to prevent the teat from collapsing.
  • the particular feature of the invention stems from the presence of at least two devices (13a) and (13b), located symmetrically with respect to one another about the axis of rotation of the teat-ring (1). This arrangement ensures in all instances that one of the one-way valves (13a) or (13b) is triggered in the event of the other one being obstructed or malfunctioning.
  • the teat (3) and the skirt (4) are made of a flexible nontoxic nonallergenic polymer material chosen from silicone, rubber, latex or any other polymer material having similar physico-chemical properties.
  • the ring (6) itself is made of a rigid nontoxic, nonallergenic polymer material chosen from polypropylene (PP), polybutylene terephthalate (PBT), polyethylene terephthalate (PET), a bioplastic such as polyethylene furanoate (PEF), a copolymer such as Tritan ® , polyphenylsulfone (PPSU), a polycarbonate or any other thermoplastic copolymer or polymer having similar physicochemical properties, particularly a similar high melting point.
  • the teat-ring (1) may advantageously be manufactured by overmolding; overmolding involves injecting a material in liquid form onto a solid insert made of a material of the rigid polymer type. The material injected in liquid form is then solidified through a thermochemical reaction.
  • the materials considered here are of the polypropylene (PP) or polybutylene terephthalate (PBT) type for the ring and liquid silicone (LSR) type for the teat.
  • LSR is a material that exhibits excellent tensile strength and resistance to tearing, is hydrophobic, flexible, antibacterial, anti UV and biocompatible. Its relatively high molding temperature of 177°C is high enough to soften certain initially rigid supports, notably polyacrylonitrile-butadiene-styrene (ABS) or polyethylene (PE), but remains largely compatible with polybutylene terephthalate (PBT) for example.
  • ABS polyacrylonitrile-butadiene-styrene
  • PE polyethylene
  • the adhesion between the overmolding materials is obtained by virtue of a chemical bond made between the overmolded materials. It is of course very important to take account of the compatibility of the materials in order to obtain the required secureness of bonding.
  • the incorporation of a suitable mechanical-connection process that further strengthens the adhesion between the components involved at their interface is an essential aspect of the invention.
  • An undercut represents a good example of mechanical adhesion.
  • This technology allows two components to be paired definitively and irreversibly. It thus avoids complex assemblies, simplifies the design of the products and makes it possible to improve the physico-chemical properties of numerous injection-molded components.
  • Said body of the baby bottle is most generally made of a rigid or semirigid polymer material such as polypropylene (PP) or polyethylene terephthalate (PET) or Tritan ® for example; it may also be made of glass.
