Definitions

  • the invention relates to a suction bottle with a bottle body which is provided in the region of its bottom with a microporous air inflow device which allows outside air to flow in, but which prevents liquid bottle content from escaping.
  • suction bottles are used for the administration of liquid food, such as tea or porridge, to infants and young children, and for this purpose they have a teat in the ready-to-use state, which is clamped onto the bottle neck, for example with the aid of a screw cap.
  • liquid food such as tea or porridge
  • suction bottles there is the problem that when the contents are sucked by the suction device, a negative pressure is created in the bottle, which often significantly impairs the drinking process.
  • it is therefore necessary to ensure that the air enters the inside of the bottle which is usually done by interrupting the drinking process so that air can get into the inside of the bottle through the teat. Of course, this disrupts food intake. Accordingly, solutions have already been proposed (cf., for example, US Pat.
  • a suction bottle of the type specified is finally known, in which a screw cap is also attached to the lower end of the suction bottle to one with this screw cap
  • Microporous membrane attached to the bottom open bottle body as a base plate. With regard to its pores, this micro-pore membrane is designed in such a way that it prevents liquid from escaping but allows air to enter.
  • the membrane is in particular enclosed between two grid plates as support elements, and the air inflow device thus formed is thus relatively complicated and expensive, and there is also the disadvantage that cleaning is difficult.
  • the thread formation with the screw cap means a substantial additional structural effort, so that such a suction bottle can hardly be produced economically.
  • the suction bottle according to the invention of the type mentioned at the outset is characterized in that the micropores are provided directly in the bottle body in the region of the base and the base is formed in one piece with the rest of the bottle body.
  • the invention takes advantage of the possibilities of modern laser technology with which different materials, such as Polycarbonate, from which the bottle body is made, for example, can be drilled with holes whose dimensions are so small that they prevent the passage of liquid molecules, such as water molecules, but allow the passage of air molecules.
  • the invention also relates to a method for producing a feeding bottle as stated above, and this method is characterized according to the invention in that after the bottle body is made of plastic, for example in a blowing process, the micropores in the bottom area are burned in with the aid of a laser beam.
  • a sufficiently high-energy laser in particular a CO2 laser, is preferably used to burn in the micropores.
  • micropores in the bottle body can be attached both in the bottom and in its side wall adjacent to the bottom, so that when using the feeding bottle, when drinking, the pressure compensation air can enter the inside of the bottle at the end of the bottle remote from the teat.
  • the desired pressure equalization and for the manufacture of the feeding bottle if the micropores are only provided in the bottom of the bottle body.
  • the micropores are provided only in an inwardly curved central zone of the bottom of the bottle body.
  • the inward curvature increases the overall stability of the bottle bottom, so that none of the cross-sectional shape and thus the function of the Deformation of the bottle body in the region of the bottom which impairs micropores is possible, and on the other hand the micropores are also well protected against soiling because they are at a distance from the base when the bottle is parked.
  • the suction bottle shown in FIG. 1 in its complete configuration consists in a conventional manner of a bottle body 1, which is closed at the bottom by a one-piece bottom 2.
  • This bottle body 1 can be produced, for example, in a conventional blowing process from a plastic, such as polycarbonate.
  • a screw cap 3 On the open top of the bottle body 1, which is not visible in the drawing, a screw cap 3 is screwed on in the manner of a union nut, with which a teat 4 can be attached to the bottle body 1.
  • the bottom is to allow air to enter the inside of the bottle when drinking with such a feeding bottle 2 of the bottle body 1 are provided with micropores 5 in the form of very fine bores, which are provided, for example, in a pattern of concentric circles or radial rays in an inwardly curved central zone 6 of the base 2 of the bottle body 1.
  • micropores 5 in the form of very fine bores, which are provided, for example, in a pattern of concentric circles or radial rays in an inwardly curved central zone 6 of the base 2 of the bottle body 1.
  • the diameter of the micropores 5 is so small that water and other liquid food cannot pass through the micropores 5 due to the surface tension, i.e. there is also no capillary action, but air can enter the inside of the bottle under the vacuum created by sucking out the contents of the bottle. It should also be noted that the pore size is such that the pores are not blocked by the contents of the bottle. It is then important that the air inlet for pressure equalization takes place in the area of the bottle base 2, specifically in the base 2 itself and / or in the adjacent side wall area, as indicated in Fig. 2 at 5 ', i.e. the air entry is as far away from the teat 4 as possible to prevent the child from swallowing the incoming air while drinking.
  • the number of micropores 5 and 5 ' is dimensioned such that, in the case of a negative pressure, which can be caused by small children when drinking, a corresponding pressure equalization is made possible by the air inlet, i.e. as much volume per unit of time the infant can suck, so much volume of air per unit of time should be able to enter the bottle.
  • the total cross-sectional area of the micropores 5 and 5 ', and accordingly the number of micropores depends on this. In this connection, it should be mentioned that the arrangement of the micropores 5 is illustrated only very schematically in the representation of FIG. 3, and that, as a rule, significantly more micropores 5 than shown are to be provided in order to ensure sufficient air entry.
  • the size of the micropores 5 or 5 'can be dependent on the bottle material used and the liquid food for which the bottle is intended (either for thicker, mushy food or for tea etc.) can be determined.
  • the micropores 5 and 5 'can have a round cross section with a diameter of a few microns, up to about 50 microns or slightly above, with a bottom thickness of 1-1.5 mm (bottle body made of polycarbonate).
  • micropores 5 can be similar to a cylindrical to conical bore.
  • a micropore 5 is shown which is conical in longitudinal or axial section and which has a larger diameter on the outside 8 of the bottle, e.g. in the range of 50 ⁇ m to 100 ⁇ m than on the inside 9 where the diameter e.g. can be about 5 microns.
  • the bottle body 1 of which consisted of polycarbonate with a wall thickness of approximately 1 mm, and in which approximately 150 to 200 micropores with a conical shape according to FIG. 4, with an inside diameter of 3 ⁇ m to 7 ⁇ m and an outside diameter of 50 ⁇ m to 100 ⁇ m, were baked in the bottom area.
  • the micropores 5 'in FIG. 2 only in the side wall of the bottle body 1, approximately in 1 cm to a height of 2 cm above the floor 2 or the stand 7.
  • a sharply focused beam of a high-power laser in particular a CO2 laser, is used, with which the material of the previously e.g. bottle body 1 produced in a blowing process is melted or evaporated.
  • a laser with a power of a few 100 mJ or a few J can be used, it also being possible to burn in several micropores 5 or 5 'at the same time (for example with the aid of a beam splitter installed in the beam path).
