Definitions

  • Nipples for baby feeding are used both in hospital sur­roundings and in private households, wherein in hospitals it is usually a matter of once-only use, while at home the nipp­les can be boiled. It is an object of the present invention to improve prior nipples as known from US-A-3.203.569.
  • the present invention provides a nipple comprising a sucking end that can be provided with one or more holes, a flange forming an entity therewith and extending in radial direction relative to the centre line of the nipple, in order to fix the nipple therewith onto a supply holder, wherein a dish-shaped non-return valve is arranged in this flange.
  • nipple prevents an underpressure being built up in a bottle or supply holder for baby food through the sucking of the baby, which makes sucking difficult, while it also prevents baby food being able to leak out of the supply holder in the absence of underpressure; a non-return valve is provided which gives a good sealing against a holder screw to be arranged on the supply holder in addition to a non-return valve which opens at a small underpressure.
  • the nipple is preferably injection moulded from syn­thetic, non-silicon holding rubber, also referred to as ther­moplastic rubber, which has the same properties as rubber but which requires no vulcanizing. Tensile strengths of 150-­5000 psi and a Shore A-hardness of 28-95 can be used with this material. A strong nipple is provided herewith, while because of the strength of the material the non-return valve can be embodied with a small thickness of this material. The non-return valve will therefore open easily, while the sealing edge gives good sealing against a holder screw if no under­ pressure is built up in the holder. It is moreover important that this material is absolutely safe for a baby.
  • a supply holder or bottle 1 can be screwed a holder screw or closing means 2 between which a nipple (fig. 1) can be clamped.
  • a sucking end 4 of the nipple 3 is provided with three conical holes 6.
  • a non-return valve 8 Arranged in a flange or collar 7 which is injection moulded from one piece with the sucking end 4 is a non-return valve 8 which is injection moulded together with the nipple 3. If through the sucking of a baby an underpressure results in the bottle 1 (fig. 2), air can pass between the holder screw edge and the neck of the nipple into a dish 9 since the sealing edge 11 is released through the underpressure. From the dish 9 the underpressure passes into the interior of the bottle 1, whereafter the sealing edge 11 closes and prevents the liquid content leaking out of the bottle along the neck of the nipple.
  • a nipple according to the present invention is preferably injection moulded from a thermoplastic rubber such as commer­cially available under the names Kraton R and Evoprene R .
  • This material has a high tensile strength with rubber-like proper­ties without vulcanizing having to take place. In addition the material displays good temperature characteristics.
