Definitions

  • the invention relates to a teat according to the preamble of patent claim 1 and a teat unit according to the preamble of claim 12 or 13.
  • Teat nipples should be easy to attach and easy to clean. Furthermore, they should allow the infant to a possibly nature-inspired sucking, so that he can switch back and forth between the mother's breast and feeding bottle without Sauggefirrung.
  • US 7 320 678 discloses, for example, a teat with a radially outwardly projecting flange and extending in the mouthpiece, projecting into the body of the teat cylindrical suction tube, through which the milk is sucked from the bottle to the suction port of the mouthpiece.
  • This suction tube must be inserted into a corresponding receiving tube of the receiving unit. This is relatively difficult to do. Furthermore, this teat can be poorly cleaned.
  • US 1 904 710 discloses a teat which folds down at a first location.
  • US 5,897,007 describes a teat with an inner tube with a suction channel, which is formed in the region of the upper end of the mouthpiece.
  • the inventive suction nipple for connection to a receiving unit of a beverage container has a main body and an adjoining the main body, tapered relative to the main body mouthpiece with at least one suction port through which the liquid exits the teat to the outside, and a free end.
  • the teat has a first connecting element for connection to the receiving unit and a second connecting element for connection to the receiving unit and a suction channel.
  • the suction channel runs in the mouthpiece. It opens with a first end in the suction opening and is directed with a second end to the base body. This second end forms the first connection element for sealing connection with the receiving unit.
  • the main body is designed to be foldable towards the free end of the mouthpiece, and the teat is further designed to be foldable at at least one second location.
  • the teat has a stable ground state, a first stable folded state and at least a second stable folded state, wherein the at least second stable state differs in the external appearance from the first stable state and the ground state.
  • the mouthpiece has two sections, wherein the mouthpiece is designed such that it can be folded over in the transition area between these two sections.
  • the mouthpiece in a region between its free end and its transition to the main body designed umklappbar.
  • the suction channel extends at least partially in a tube which extends at least partially inside the mouthpiece and spaced from an inside of the mouthpiece.
  • the tube has a first tube end connected to the mouthpiece.
  • a second free tube end forms the second end of the suction channel.
  • the first end of the tube ends at a distance from the free end of the mouthpiece inside the mouthpiece.
  • the suction opening is in the free end of the mouthpiece, i. in its foremost tip and consists of a single hole.
  • the suction opening can also be arranged not laterally in the tip, but laterally in the front region of the mouthpiece. It can also be formed in both variants by several holes.
  • the first connecting means seals the connection of the suction channel with the receiving unit and thus with the interior of the beverage container against the remaining teat and thus against the outside.
  • the teat itself is but mainly by the second connecting means, preferably a circumferential flange of the body, connected to the receiving unit. This connection is subject to standards that must be met. The nipple should not come off the beverage container during suckling when the baby is sucking or pulling on it.
  • the first connecting element Since the main body is folded down or everted in the first appearance, the first connecting element is more accessible. It is easier to connect to the recording unit.
  • the tube can relatively easily be pushed back into the mouthpiece from the second everted state and thus restore the normal position of use.
  • This can be achieved, for example, by designing the mouthpiece to be conical at least over the area penetrated by the tube and / or to make the tube hollow-cylindrical in this area.
  • Another advantage is that the simple and in particular the double-folded teat can be better cleaned because any complex structures in the interior of the body, such as the first connecting element, are exposed and are more accessible for the purpose of cleaning.
  • the suction nipple can be produced in one piece, for example, even in a simple and in particular in a doubly folded state. This facilitates on the one hand the production and lowers the production costs. Furthermore, the inner region of the teat, in particular the space between the tube and mouthpiece, can be provided more easily with radial or axial ribs, dents, nubs or other internal structures.
  • the mouthpiece in a top, the suction opening adjacent region is single-walled and executed in a lower, the base body adjacent region double-walled.
  • the teat In the folded state of the body surfaces are exposed to the touch, which are not in contact with a liquid flowing through the teat under normal use of the teat, wherein the teat is connected by holding these surfaces with the receiving unit as intended.
  • the teat is connectable without additional tools or tools with the receiving unit or mounted on this.
  • the folded body can be touched on its inside and the mouthpiece must not be touched at any time. Since inside the main body of the tubular suction channel is present, and the inside of the body does not come into contact with the liquid to be drunk.
  • the suction channel extends between the first tube end and the suction opening in a chamber in the interior of the mouthpiece.
  • This chamber changes its shape during suction and adapts to the baby's sucking process and mouth similar to the natural nipple of the mother's breast.
  • the mouthpiece and the tube are bendable at least in the region of the chamber, in order to adapt to the suction optimally and as lifelike as possible.
  • This nipple allows a lifelike replica, so that Saugverwirrung can be avoided when changing from teat to the natural mother's breast.
  • spacers may be arranged in the form of radial or axial ribs, nubs, dimples or other surface structures which prevent the walls of the tube and mouthpiece from sticking or sticking together during the suction process.
  • the inventive teat can be used in a teat unit for sucking a liquid from a liquid container.
  • This Saugnippeltechnik has the teat and a flow restrictor with a through hole.
  • the teat has a mouthpiece and an integrally formed on the mouthpiece, extending towards the mouthpiece body, wherein in the mouthpiece a suction opening is present.
  • the flow restrictor determines a maximum flow of liquid flowing from the liquid container through the suction opening.
  • the flow restrictor is arranged outside the mouthpiece.
  • the suction opening has a larger cross-sectional area than the passage opening of the flow restrictor.
  • This teat unit allows a lifelike sucking. Thanks to the large opening, the mouthpiece, also called nipple, can be deformed well during the suction process, and it optimally adapts to the movements of the baby's mouth and tongue. The infant gets a similar sensation in the mouth as if it were sucking on a natural nipple of a mother's breast.
  • the mouthpiece is designed to be bendable, and in intended use, preferably no parts which stiffen the mouthpiece over a substantial part of its length project into it. In the intended use, the mouthpiece is therefore preferably deformable.
  • Typical diameters for a round suction opening are 3 to 8 mm and for a round flow limiter 0.2 to 0.7 mm.
  • the flow restrictor is located outside the mouthpiece, i. outside of that part which is put into the mouth by the infant in the intended use. As a result, the infant can not influence the flow restrictor by mechanical pressure or tension caused by his lip and mouth movements.
  • the teat according to the invention can also be used in a teat unit for sucking a liquid from a liquid container which has the teat and a flow restrictor with a passage opening.
  • the teat has a mouthpiece and an integrally formed on the mouthpiece, extending towards the mouthpiece body, wherein in the mouthpiece a suction opening is present.
  • the flow restrictor determines a maximum flow of liquid flowing from the liquid container through the suction opening.
  • the flow restrictor is arranged outside the mouthpiece and the teat unit is arranged has a one-way valve which is located outside the mouthpiece, and wherein the flow restrictor is disposed in the one-way valve or in an adjacent region thereto.
  • This Saugnippelü allows lifelike as possible, since in the suction unit only atmospheric pressure or negative pressure is present. There is no overpressure. The milk thus does not splash into the baby's mouth, but flows into the mouth according to the vacuum applied by the baby. The milk flow is approximately proportional to the vacuum applied by the infant.
  • This Saugnippelü allows a suction, which is purely vacuum-controlled and largely independent of the rest, in particular the peristaltic movement of the tongue. If the posterior region of the tongue moves towards the upper palate, no milk should flow. If this rear area moves away from the upper palate, the milk flows.
  • This teat unit takes into account the fact that the baby does not switch back and forth between vacuum and atmospheric pressure when sucking. It rather maintains a base vacuum throughout the suction process. In contrast to the arrangements according to the prior art now closes the valve upon reaching this base vacuum. If the absolute value of the applied vacuum rises above this basic vacuum, the valve opens and the milk or liquid can flow. The baby is thus able to take a break despite being able to maintain the basic vacuum, to take a breath or to recover, and to gather new strength, as happens with the mother's breast.
  • the device according to the invention opens even at a low negative pressure of 1 to 90 mmHg, preferably 20 to 70 mmHg. Even more preferred values are between 20 to 30 mmHg and 5 to 30 mmHg. These values are in their absolute value just above a typical base vacuum of a baby.
  • valve has no further influence on the milk flow during the suction process.
  • the degree of opening and operation of the valve does not affect the flow of milk through the suction port.
  • the check valve covers the passage opening of the flow restrictor. In a preferred embodiment, however, the check valve does not cover the relatively small passage opening of the flow restrictor but a larger opening.
  • This opening is preferably arranged in the flow direction of the liquid in front of the flow restrictor, i. So directed to the liquid container. However, it can also be arranged downstream of the flow restrictor in the direction of flow.
  • the opening of the flow restrictor is in the rigidly formed valve seat, i. here in the base part.
  • this opening can be covered and closed by the valve membrane.
  • it can also be arranged adjacent and lead into the dead volume.
  • the opening of the flow restrictor can be arranged in the valve membrane and closed by sealing support of the membrane on the valve seat.
  • the outflow opening is arranged adjacent to the valve seat and is not closed by the membrane, but leads into the dead volume.
  • the outflow opening can be made the same size or larger than the opening of the flow restrictor.
  • the flow restrictor can thus be arranged in, above or below the valve membrane.
  • valve and the flow restrictor or the outlet opening and the valve are arranged adjacent to each other, the dead volume, in which also a vacuum must be generated, minimized.
  • the valve or the sucker works too flawless at low flow rates.
  • the valve is easy to disassemble and therefore easy to clean the teat unit. If a membrane is used, it can be held by clamping between individual parts.
  • an umbrella valve instead of a clamped membrane with or without a well-defined opening cross-section, an umbrella valve, a beak valve or a slotted membrane can also be used.
