Definitions
- the invention relates to a teat unit according to the preamble of claim 1 and a teat according to the preamble of claim 14.
- EP 1 532 957 discloses a teat with a large suction opening and a flow restrictor arranged in the mouthpiece. Also in US 5 101 991 and BE 3 81523, the flow restrictors protrude into the mouthpiece.
- EP 0 384 394 describes a teat with a first flow restrictor with a large opening and a suction opening as a second flow restrictor with a smaller cross section.
- WO 03/013419 describes a relatively small mammal opening and a larger passage opening outside the mouthpiece.
- the passage opening is provided with a check valve.
- US 5 791 503 shows a relatively complex teat unit with a check valve.
- the inventive teat unit for sucking a liquid from a liquid container has a teat and a flow restrictor with a through hole.
- the teat has a mouthpiece with a mammal opening, from which liquid emerges from the mouthpiece to the outside, and an integrally formed on the mouthpiece, extending towards the mouthpiece body.
- the flow restrictor determines a maximum flow rate from the liquid tank ter flowing through the suction port liquid. Erf ⁇ ndungsgemäss the flow restrictor is located outside the mouthpiece, and the mammal opening has a larger cross-sectional area than the passage opening of the flow restrictor.
- the mouthpiece also called nipple
- the mouthpiece 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 bendable and, in intended use, preferably does not project any parts stiffening the mouthpiece over a substantial part of its length into it. In the intended use, the mouthpiece is therefore preferably deformable.
- a milk channel is present between the suction opening and the flow restrictor, which also has at least one diameter of the same diameter as the diameter of the suction opening. If there are several milk channels, they have at least in common over their entire length a flow opening which is larger than that of the flow limiter and which preferably corresponds at least to the diameter of the mammal opening. Preferably, the inner diameter of the milk channel over its entire length is approximately the same size as the suction opening. There is no further flow restriction in the area between the flow restrictor and the suction opening, which would limit the flow more or only approximately the same as the first mentioned flow limiter.
- the mouthpiece is formed as flexible as possible.
- the total cross-sectional area of the suction opening is many times greater than the entire cross-sectional area of the passage opening of the flow restrictor. Typical diameters for the suction opening are 3 to 8 mm and for the flow restrictor 0.2 to 0.7 mm.
- the mouthpiece can have the same softness and flexibility over its entire length. In a preferred embodiment, however, it becomes harder and / or stiffer towards the main body. Depending on the embodiment, this is done continuously or stepwise. This change can be done, for example, by increasing the wall thickness.
- the mammal opening and / or the adjacent milk channel may have a round, oval or elliptical cross-section. They can be designed rotationally or mirror-symmetrically. However, they can also have an asymmetrical shape. The same applies to the outer shape of the mouthpiece. For example, it can have a round cross-section over its entire length or, in particular, it can have a tooth-like shape (called a dental mold).
- the flow restrictor may be molded in the teat itself or it may be in another separate part of the teat unit. However, 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 unit according to the invention thus separates the functions:
- a teat unit for sucking a liquid from a liquid container. It has a teat and a flow restrictor with a through hole.
- the nipple has a mouthpiece with a suction opening and a mouthpiece formed on the, to the mouthpiece erwei- turing body on.
- the flow restrictor determines a maximum flow of liquid flowing from the liquid container out of the suction opening.
- the flow restrictor is arranged outside the mouthpiece and the teat unit has a one-way valve which is arranged outside the mouthpiece, wherein the flow restrictor is arranged in the one-way valve or in an adjacent region.
- a large suction opening is also an advantage here, but not absolutely necessary.
- the mouthpiece in this case, reinforcing elements, such as ribs have. Preferably, however, it is formed single-walled and / or unreinforced.
- suction unit In this suction unit is only atmospheric pressure or negative pressure. 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.
- the Saugnippelü erf ⁇ ndungsdire takes into account the knowledge that the baby does not change between vacuum and atmospheric pressure when sucking back and forth. It rather maintains a base vacuum throughout the suction process.
- the valve now closes 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 already 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 theirs Absolute amount 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 located in, above or below the valve diaphragm. orders be.
- 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 vacuum works perfectly even 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.
- the suction opening has a larger cross-sectional area than the passage opening of the flow restrictor.
- the milk channel between flow restrictor and suction opening over its entire length on a cross-sectional area which is greater than that of the passage opening and preferably at least equal to the size of the cross-sectional area of the suction opening.
- the suction opening may also have an equal cross-sectional area as the flow restrictor. The same applies to the milk channel.

- the upper portion of the receiving head 3 is preferably made of a softer material than the lower one. It can be arbitrarily shaped in the peripheral area. Preferably, it has peripheral support bodies or structures, in this case support cushions 341, which interact with the absorbent body or teat 4 described below. These support structures may also be formed of a hard material.
- the receiving head 3 has a protruding circumferential fastening edge 31 with a peripherally encircling outer sealing surface 310. It is planar and extends approximately perpendicular to the longitudinal center axis of the recording head. 3
- a self-contained valve membrane 37 is formed on the recording head 3. It covers the outflow opening 24 of the base part 2. In its peripheral region, which no longer covers the outflow opening 24, the valve membrane 37 has a small opening, the through-opening 32. This passage opening 32 is located above the inner surface 241 of the base ring 2.
- the valve diaphragm 37 is preferably integrally formed on the receiving head 3. Either she herself is made of a soft material and the remaining head 3 is made of a hard material. However, it may, for example, also be formed in one piece together with soft support structures 341 and glued to the hard part of the receiving head 3, welded to it or sprayed onto it.
- valve membrane 37 is surrounded by an upstanding and circumferential collar 39, which may also be formed of hard or soft material integral with the rest of the receiving head 3.
- This collar 39 preferably has circumferential outer ribs, which are not shown here.

- the mouthpiece 42 is preferably hollow cylinder-shaped or formed as a truncated cone in a known manner. It preferably forms a thin-walled hollow body with an inlet opening and a suction opening 43. It is bendable and / or flexibly deformable. Preferably, it is formed single-walled. Although it is double-walled, it should be flexible and flexible as possible, for example by having thin walls.
- the mouthpiece 42 can also be provided with internal structures, such as radial or axial ribs, knobs and dents.
- the suction opening 43 is present in the mouthpiece 42, preferably in the uppermost tip.
- This suction opening 43 is connected in the mounted state via the passage opening 32 and the flow opening 24 with the container interior, so that the baby through this opening his drink, such as tea, water or milk can drink.
- the suction opening 43 is preferably surrounded by a circumferential, inwardly directed flange 430. This gives the free end of the mouthpiece 42 stability. Moreover, the outermost edge of the material, being bent inward, see impacts better protected.
- a skirt 46 projecting towards the receiving head 3 is present.
- an inwardly projecting flange 460 is preferably formed.
- the base body 40 is bent with its lower edge inwards, so that a radially inwardly directed flange 41 is formed.
- the teat 4 can be with its base 40 over the receiving head 3.
- the skirt 46 is slipped over the collar 39 so that the flange 460 of the skirt 46 engages behind the rib of the collar and sealingly abuts.
- the flange 41 of the base body 40 engages behind the projecting edge between the upper and lower regions of the receiving head 3 and lies flat and sealingly against the outer sealing surface 310 thereof.
- the suction nipple 4 can thus be attached to the receiving head 3 or partially put over him. Subsequently, the recording head 3 can be inserted into the base part 2. The receiving head 3 can be stuck in the base part 2, if this is free, but also if it is already on the container neck 1. Since the base part 2 can still be moved slightly in the axial direction with respect to the receiving head 2, the teat 4 can optionally be slipped over the former only when the receiving head 3 and the base part 2 are plugged together.
- the valve diaphragm 37 forms a check valve, which is connected via a ring joint or - hinge 370 with the remaining receiving head.
- the outside of this ring joint 370 arranged through hole 32 forms a flow restrictor.

- the cross-sectional area of the suction opening 43 is more than 10 times, in particular more than 50 times and preferably more than 100 times larger than that of the passage opening 32.
- the entire area of the suction channel 48 extending in the mouthpiece 42 has one around the above factors larger cross-sectional area.
- Typical diameters of the suction opening 43 are 7 mm and the passage opening is 0.25 to 0.7 mm.
- the suction opening 43 and the suction channel 48 has a round cross-section in the upper region, as can be seen in FIG. Since the mouthpiece 42 is formed relatively soft, it is deformed in the intended use and the suction port 43 and the suction channel 48 in the adjacent area, for example, assume an oval shape, as shown in Figure 6.
- the mouthpiece 42 may be arbitrarily shaped as long as it remains flexible and pliable. As can be seen in particular in FIG. 3, the wall of the mouthpiece 42 can increase in thickness relative to the head part 3. This is done here gradually. Typical wall thicknesses are: tl about 0.5 mm, t2 about 1.5 mm, t3 and t4 about 2.0 mm. Other masses are possible.
- a taper 420 in the inner diameter is present in the mouthpiece 42, so that a deforming cavity 421 is formed in the region of the suction opening 43. As can be seen in FIGS. 3 to 6, the cross-section of this cavity 421 deforms as intended, the deformation depending on the baby and the suction process. In particular, the cavity 421 may become longer but narrower and change from a round cross-section to an oval cross-section. The shape of the teat may change during the suction process.
- both the flow restrictor and the check valve are present.
- no check valve is present, but only the flow restrictor forming passage opening 32.
- This may be centrally or centrally located in the head part 3.

- the liquid container may be provided with the Aus Wegöffhung 24, which is sealed by the membrane.
- the outflow opening 24 may be selected to be so small that it itself forms the passage opening and thus the flow restrictor.
- the teat 4 may be attached in other ways.
- the skirt 46 may be inserted into the collar 39.
- the nipple may have direct contact with the liquid container.
- the teaching according to the invention can also be applied to the initially mentioned teat nipples, for example according to EP 1 532 957.

- Curve 6 is the volume flow in ml / s as a function of time in seconds.
- the reference numeral 7 shows the physiological vacuum curve of the baby, the vacuum in mmHg and the time is also given in seconds.
- 8 designates the release threshold of the valve, which is preferably 20 to 30 mmHg. As can be seen in FIG. 8, no milk flows in the phases in which the absolute value of the vacuum generated by the baby is below this triggering threshold. These phases are designated by A in the figure. If the applied vacuum is sufficient to open the valve, milk flows. These are the phases B.

- Figure 7 shows the behavior of a Saugnippelü according to the prior art. Same curves are provided with the same reference numerals.
- the milk flow is not interrupted and a continuous milk flow is generated.
- the baby can not recover in between, but must constantly swallow milk, even if it maintains only the base vacuum. This does not correspond to the situation at the mother's breast.
- the radially inwardly directed flange of the body can be aligned with the ⁇ ffhungsebene of the body or it can also be directed at an angle down from the opening of the body out.
- a differently shaped inner connecting means may also be present.
- a suction channel having a radially outwardly projecting flange, which engages behind a correspondingly shaped receptacle of the receiving unit, in particular of the receiving head.
- the free end of the milk or suction channel does not necessarily have to protrude into the main body. It is also possible that the suction channel ends with the end of the mouthpiece directed towards the main body.
- This free end of the suction channel is shaped so that it allows a sealing, preferably pluggable connection with the Aufhah- me unit, for example by provid- ing suitable sealant on or in the suction channel.
- this end region of the suction channel may be formed as a cone, which receives the receiving unit under bias.
- the mouthpiece and / or the suction channel can also be provided with internal structures, for example radial or axial grooves, ribs, dents or nubs.
- the suction channel can also be provided on the outside with such internal structures.
