Definitions

  • the present invention relates to a membrane for bottom ventilation of a baby bottle containing liquid to be sucked, which has an improved air inlet cut.
  • valves are provided to compensate for the negative pressure generated inside the baby bottle as the baby sucks the liquid, mainly milk, by creating a passage for air between the interior of the baby bottle and the outside environment.
  • a very common type of valve having the above mentioned purpose consists of a calibrated cut formed on a flexible area of a silicone membrane device inserted in the bottom cover of the baby bottle, which can be removed using conventional threads.
  • the cut is formed in a central flexible region of the membrane using a sharp blade of a suitably defined size, without causing material removal.
  • the object of the present invention is to solve the problem of progressive healing of the cut formed on the membrane element of a ventilation device to equalize the pressure inside a baby bottle during suction.
  • numeral 1 designates the baby bottle containing the liquid to be sucked, namely milk.
  • a cover 4 is removably connected to the lower end 2, e.g. using a thread 3, to close the opening 2a of the lower end 2.
  • the cover 4 conventionally accommodates a device for venting the bottle 1, generally referenced 5, which is intended to balance the pressure inside the bottle 1, as the liquid is being sucked by the baby through the nipple, generally referenced 6 in Figure 1 .
  • the latter is conventionally attached to the upper end 7 of the bottle 1, by means of a nut 8 with the interposition of the threads 9 and 10 and with edge 11 of the nut 8 fitting in the annular groove 12 of the nipple 6.
  • the ventilation device 5 is supported, in the cover 4, by a dome-shaped element 16 which has one or more holes 18 arranged around a cusp element 19 near its end 17 distal from the bottom of the cover 4.
  • the ventilation device 5 comprises a membrane element 20 made of silicone material having a flexible central portion 21 formed therein, which rests on the cusp element 19 and above the holes 18.
  • One or more cuts 22 are centrally formed in said flexible portion 21 of the membrane 20. Each cut opens as its facing edges move apart from each other, thereby allowing the ingress of outside air into the baby bottle 1 through the holes 18 once the flexible portion 21 of the cusp element 19 has been lifted.
  • At least one of the opposed mutually facing surfaces 23, 23a of the cuts 22, as schematically shown in Figure 4 is formed with roughness.
  • the surfaces 23, 23a are both formed with roughness, for example, with a plurality of alternating recesses and protrusions.
  • the recesses and protrusions that form such roughness have values ranging from 10 to 200 microns and can be formed on the surfaces of the cut by using a suitable file blade.
