Definitions

  • the invention relates to a teat, particularly for babies and small children.
  • the teat can in particular be designed as a feeding teat or as a drinking aid (e.g. feeding spout or drinking spout) in accordance with European standard EN 14350-1.
  • Drinking teats are used before milk and other liquid food are administered, particularly to infants and young children. They have a hollow suction part with a passage opening for liquid food. The suction part is connected in one piece at the bottom with a circular disk-shaped suction flange, which is used to attach to the mouth of a vessel.
  • the vessel is in particular a drinking bottle (feeding bottle), drinking cup or feeding bag.
  • a fastening ring is used which has a cylindrical jacket with fastening means for fastening to fastening means of the vessel.
  • the fastening means are usually threads on the inner circumference of the jacket and on the outer circumference of the vessel.
  • the fastening ring has an inwardly protruding, circular disk-shaped annular flange which engages over the suction flange and presses against the front edge of the mouth of the vessel.
  • Feeding teats are usually made entirely of soft, elastic material.
  • Drinking aids and bills are often also made of soft, elastic material.
  • drinking aids made of hard (or hard-elastic) plastic or a combination of hard and soft materials are known.
  • drinking aids made of a hard plastic with a valve insert made of soft elastic material, which is clamped at the edge between the drinking aid and the mouth of the vessel are known.
  • teats When sucking on the suction part, a negative pressure arises in the vessel, which makes it difficult to remove the liquid and leads to the collapse of a soft, elastic one Teat can lead.
  • teats have a ventilation valve.
  • the ventilation valve opens when there is a certain negative pressure in the vessel, so that the pressure is equalized with the environment.
  • Drinking teats are known in which the passage opening is one or more circular drinking holes.
  • the drinking holes are produced, for example, by means of a correspondingly shaped injection molding or immersion tool, by punching or piercing with needles or by drilling with a steel drill, a water jet or a laser beam.
  • the production of drinking holes by means of a laser beam is in the DE 40 05 410 A1 , U.S. 6,032,810A and U.S. 4,623,069A described.
  • FR 2 302 724 A describes a teat with micro-perforations, the number and diameter of which are determined depending on the volume flow to be achieved.
  • the micro-perforations can be produced by means of laser, ultrasound or any other technique such as mechanical, chemical or other processes.
  • the micro-perforations are formed in a vertical section through the wall of the suction part by uniform or uneven branches that open into the outside of the suction part, with several branches being fed by a single channel that opens on the inside of the suction part.
  • the ramified and curved micro-perforations cannot be produced using straight laser beams.
  • Drinking holes are so small that no significant amounts of liquid can accidentally escape. Because of their small size, however, a high suction pressure has to be applied in order to remove a larger amount of liquid.
  • drinking teats are known in which the passage openings are designed as drinking slots. Such teats are for example in the EP 1 924 234 B1 and EP 2 182 910 B1 described. Both patent publications describe teats with two parallel drinking slots. Drinking teats with two intersecting drinking slots are also known. If there is no suction on the suction part, they are Edges of the drinking slits sealingly against one another. When sucking, the drinking slots open so that liquid can escape. Conventionally, the drinking slits are cut with a knife. Conventional teats with drinking slots have a good leakage security and allow a high flow of liquid food. However, the production is complex. In addition, the cut surfaces of the drinking slits tend to stick together and then require a high opening pressure. Another disadvantage is that drinking slits can tear at the ends and the teat becomes unusable as a result.
  • the invention is based on the object of creating a teat that seals reliably, enables a high flow of liquid food and has more favorable manufacturing properties.
  • the teat according to the invention especially for infants and small children, has a teat with several interconnected drinking slots and a teat flange connected to the lower end of the teat for attachment to the front edge of a mouth of a vessel, characterized in that the drinking slots are cut into the teat by means of a laser beam and a small gap are opened in the unloaded state of the teat.
  • the drinking teat according to the invention has several drinking slots which are cut into the teat part by means of a laser beam.
  • the drinking slits are also opened a small gap when the teat is not sucking, ie when the teat is not under load.
  • the gap width of the gap is kept so small that the capillary action and the surface tension of the cut surfaces achieve a sufficient tightness of the teat, which prevents unintentional leakage of liquid food.
  • the precise production of Drinking slots with a sufficiently small gap width possible.
  • the drinking slot allows large amounts of liquid food to escape by sucking on the teat.
  • the drinking slits can be produced without contact by means of a laser beam, which allows high production speeds. It is also advantageous that the production by means of a laser beam enables any contours of the drinking slots. Another advantage is that the ends of the drinking slits produced by means of a laser beam tend to tear less than when produced by means of a knife, because the ends are rounded off by the laser beam and are less prone to tearing.
  • the gap width of the drinking slits is at least 0.1 mm, preferably at least 0.2 mm and / or at most 0.4 mm, preferably at most 0.3 mm. These gap widths can be easily produced using a laser beam and prevent unintentional leakage of liquid food.
  • the radius of the rounded ends of the drinking slots is equal to or exceeds the gap width of the drinking slots. If the radius of the rounded ends corresponds to the gap width, the inadvertent leakage of liquid is counteracted particularly effectively. In principle, however, it is also possible for the radius of the rounded ends to exceed the gap width. The latter can be achieved in that the laser beam remains at the ends for a short period of time or the incision is controlled accordingly by means of the laser beam. The larger radii can better prevent tearing.
  • the drinking slits can have any shape, in particular a straight or a zigzag or a curved shape (e.g. a C-shape).
  • the teat can have several drinking slots with the same or different shapes.

  • This embodiment also favors a drinking teat with drinking slots that are only opened by a very small gap when the suction part is not being sucked, so that they have the desired tightness.
  • the drinking slots provide a sufficiently large opening for the desired flow rate to exit.
  • Drinking slots with a common interface can be combined with drinking slots with a branched course.
  • the teat has drinking slots which each extend away from the interface on both sides. These are e.g. drinking slots arranged in a cross or X-shape. According to a further embodiment, the teat has drinking slots which each extend away from the common interface on only one side. These are, for example, three drinking slots arranged in a Y-shape.
  • the teat has several arrangements of several interconnected drinking slots.
  • the gap width can be further reduced in favor of the tightness of the drinking teat and yet the desired flow rate can be ensured even when sucking on the drinking teat.
