Description

Technical area

The present invention relates to a suction nipple for milk bottles, i. Milk bottles for babies.

State of the art

Breastfeeding is the most natural and best way to feed a baby. A large number of scientific studies prove that breast milk is of great importance for the baby's development. The immune system is stronger, and the baby is stronger. Likewise, the mechanical effect of sucking on the chest has a significant effect on the development of the palate and the muscles. Unfortunately, breastfeeding is not always or only partially possible: e.g. if the mother goes back to work or is absent for breastfeeding, in case of illnesses, in case of sore nipples, or if the mother has too little milk and the baby additionally needs a substitute food.

In these situations, the milk is pumped out and given to the baby with a bottle, a spoon, a cup or with a fingerfeeding. Unfortunately, today's teat nipples have negative effects on breastfeeding. The problem is that the baby has to learn to drink at the breast. When it gets used to it and then has to drink from the bottle, it sucks for the first moment as on the chest. The baby then realizes that the nipple resp. the ratio vacuum / milk flow behaves differently. Likewise, the peristaltic tongue movement can not be performed to the same extent. With many conventional teat nipples the baby has to stop the milk flow with his tongue instead of the vacuum.

Most teat nipples are hollow inside and have holes or slits at the exit. However, the hole diameters at the outlet rarely have the optimal diameter: either the passages are too large or too small. In addition, teat nipples, which are hollow inside, do not have the correct elasticity. They are often too soft or too hard. Another weakness in today's teat cups is that there is virtually no longitudinal expansion of the mouthpiece during the suction phase.

An influencing factor during sucking is the interface Babylippe / Areola with regard to lip support. The support of the lips is not designed close to nature in conventional nipples, because the nipples are not included in the operation of the lip support and because they are hollow and have too little elasticity.

Although nipples with valves have been developed (see EP 1 416 900 B1 . US 2004/144744 . US 5 035 340 ). Furthermore, there are patents of teat cups with capillaries (see patent MXPA 05004972 or US 6588613 ), which should simulate the natural functioning in a better way. Unfortunately, these systems have several disadvantages in the application and are especially problematic in the production. Furthermore, the cleaning is difficult, resulting in disadvantages in terms of hygiene.

WO 03/013419 discloses a suction nipple for a milk bottle with an inner and outer part, both parts being designed as flexible membranes which form a chamber between them. The inner part is provided with a valve which controls the flow of milk from the bottle into the chamber. The outer part has at its top an opening through which the baby can suck the milk out of the chamber. The two parts are shaped so that when squeezed or sucked on the outer part of the valve is closed and when unloading the outer part of the valve is opened.

WO 02/22073 shows a two-piece teat for a drinking cup, in which case the inner part acts as a valve. At rest, the inner part presses spring-loaded up against the opening of the outer part, so that the teat is tight. If pressure is exerted, the inner part sinks down and releases the opening of the outer part. Now, when the outer part is compressed, it lies close to the side walls of the inner part, in the unloaded state, however, it releases through channels to the cup.

BE 381523 describes a suction bottle with a teat and an intermediate plate to be arranged between the bottle and nipple. This intermediate plate has capillaries to regulate the flow of milk.

GB 2 370 787 discloses a suction bottle with a valve arranged in the suction nipple, which is intended to regulate the flow of milk.

In today's nipples, the natural overall function is not replicated. Individual sub-functions are fulfilled by different providers, but there is no product that satisfactorily replicates all functions of breastfeeding.

Because of the many weak points a natural behavior when drinking from the milk bottle with the conventional nipples is not possible. Due to these shortcomings, the baby is irritated and accustomed to a wrong sucking, which negatively affects the natural breastfeeding. For breastfeeding consultants one speaks of "Saugverwirrung".

Presentation of the invention

It is therefore an object of the invention to provide a teat which comes as close as possible to the suction behavior of the human breast.

This object is achieved by a teat with the features of claim 1.

The inventive suction nipple for milk bottles has a receiving head made of a dimensionally stable material and an absorbent body made of a rubber-elastic material, wherein the receiving head is formed as the core of the teat and the absorbent body is slipped over the receiving head, wherein the absorbent body a mouthpiece and an outlet channel extending therein Milk, so that when the negative pressure generated in the mouthpiece milk from the milk bottle can get into the outlet, the absorbent body in a basic position with an inner surface sealingly bears against at least a portion of an outer surface of the receiving head. This teat nipple is characterized by capillary milk channels which are present in this contact area of the absorbent body with the receiving head and which lead in the direction of the outlet channel extending in the mouthpiece, so that when generated in the mouthpiece negative pressure milk from the milk bottle through the milk channels flow into the outlet channel can, with no negative pressure of the absorbent body is moved back to its normal position and the milk flow is interrupted.

In one embodiment, an inlet channel leading to the interior of the bottle and at least one channel emerging from it to the outer surface of the receiving head are provided in the receiving head. The milk channels communicate with the at least one channel of the pickup head.

The milk channels are arranged in the inner surface of the absorbent body and / or in the outer surface of the receiving head, wherein they are each open to the other surface

The milk channels are designed as capillaries. Under capillaries narrow channels are understood in which surface forces are effective, so that no milk flows without generated vacuum.

In a further embodiment of the invention, an inlet channel leading to the interior of the bottle is provided in the receiving head. This teat is characterized by at least one channel which is provided in the receiving head and which exits from the inlet channel to the outer surface of the receiving head in the contact area of the absorbent body, so that when the negative pressure generated in the mouthpiece milk from the milk bottle can flow through the milk channels in the outlet channel, the absorbent body is moved back into its normal position and the milk flow is interrupted without negative pressure ,

The functionality is essentially the same as the typical breastfeeding on the human breast. By sucking the baby at the nipple or at its tip, a vacuum is created and milk from the bottle between the outer surface of the Receiving head and the inner wall of the absorbent carried through to the exit.

The natural sucking consists essentially of the functions or the parameters: suction strength, sucking rhythm, tongue movement, supporting the lips and pressure on the nipple, and areola. The teat according to the invention now makes possible an overall system which simulates all essential still functions or parameters. For example, if no vacuum and no pressure is produced by the baby (by means of lips or tongue), no milk is released. If the nipple is compressed without creating a vacuum, there will be no milk delivery. Only when vacuum and pressure are generated on the nipple, the milk flows. The amount of milk can thus be controlled by the vacuum level, suction rhythm and by the pressure of the tongue and lips.

The nipple feels soft and flexible. It is preferably made of a resilient solid material, which expands in the longitudinal direction under vacuum - similar to the nipple. The lip support is adaptable and elastic.

Thanks to the teat according to the invention, the vacuum / milk flow behavior is comparable to the milk flow of the human breast.

The inventive teat is also inexpensive to produce and it can be optimally cleaned.

By sucking on the mouthpiece and the peristaltic tongue movement, a vacuum is created. In vacuum construction and by the tongue movement, the mouthpiece is deformed and extended axially. In addition, the lip support deforms, so that the nipple in baby's mouth is sucked far towards the palate. As a result of this movement, the absorbent body lifts off from the receiving head in the region of the milk channel closure wall and opens the passage to the outlet channel. The milk flows from the bottle through any milk channels and through any milk chambers to the outlet channel. The milk channels are lying between the outer surface of the receiving head and the inner wall of the absorbent body. The task of the milk channels is to dispense the milk from the bottle in proportion to the sucking behavior of the baby. The capillary cross-sections and capillary lengths determine the milk flow in relation to the vacuum level. Above all, the milk chambers are used by the mother to visually monitor whether there is no air in the system to prevent the baby from swallowing air while drinking. The milk chambers are thus optional.

The actual absorbent body consists in a preferred embodiment of a soft elastic silicone outer part and a harder silicone inner part, which are preferably prepared by multi-component injection molding and are permanently connected to each other. The outer soft part of the absorbent body can preferably be felt and deformed similar to the nipple and the areola. The inner harder part of the 2-component silicone absorbent body gives the absorbent the necessary stability. The inner part of the absorbent body is used in addition to the stabilization especially the protection against a possible biting through in the region of the elastic mouthpiece. The inner part is shown in the region of the mouthpiece as a cylindrical tube. As through-bite protection, other geometric shapes or materials such as e.g. a spiral or a tissue insert in question.

As already mentioned, the flow speed depends on the vacuum. With a small vacuum little milk flows, at higher vacuum accordingly more. No matter which vacuum suction curve the baby pretends, the system adapts. For example, a baby can keep the vacuum at a high level for a long time, and the milk flows constantly. As soon as the vacuum is reduced, the milk flow is reduced. If no vacuum is exerted on the nipple between the suction phases, the absorbent body rests on the milk channel closure wall and closes the outlet. Thus, the suction nipple system adapts to the suckling behavior of the baby at any stage, no matter how long the baby keeps the vacuum upright. The milk is delivered according to the suction behavior.

With the present invention, the natural breastfeeding can be further promoted because the baby is not confused by the teat and thus no longer the risk that the breastfeeding is terminated early.

Particularly advantageous embodiments of the invention are defined in the dependent claims. The features of the dependent claims can be in the same way as claim 1 on the claims 18 and 19 relate.

Ways to carry out the invention

The invention described below relates to a teat for milk bottles or a hydration system for infant feeding.

As the FIGS. 1 and 1 * show schematically, the system consists of a suction body 1 made of rubber-elastic material, such as silicone, and a form a receptacle for the absorbent body 1 forming dimensionally stable or rigid Distributor head or receiving head 2, here with an integrated threaded flange or threaded ring 203 for releasably screwing the receiving head 2 on a milk bottle 3. The receiving head 2 is preferably made of a rigid plastic by injection molding. For example, it is made of hard plastic.

The parts 1, 2, 2 'described above form the teat according to the invention. A lying between the suction nipple and bottle 3 sealing ring 202 may be integrated as a separate part in the receiving head 2 or formed separately. In particular, it can be designed as a multi-component injection molded part.

The absorbent body 1 preferably has an outer shape which corresponds to the known suction nipple and is modeled on the nipple of a human mother's breast. He has a nipple, here in the form of a tubular mouthpiece 117 with a milk outlet 123, which widens to a lip support 119 (see FIG. 4 ). The nipple may be eccentric.

The absorbent body 1 is preferably formed thick-walled, i. it is essentially not hollow except for a recess about the receiving head 2 to be inverted. The recess is dimensioned such that the absorbent body 1 in the resting state, i. without external vacuum, sealingly resting on the receiving head 2. From the mentioned recess, a milk outlet channel 106 leads to the milk outlet 123 at the outer tip of the absorbent body 1.

The absorbent body 1 may be formed in one piece, as in FIG. 1 is shown. However, it can also be multi-piece, in particular designed in two parts, as in FIG. 1 * is shown. Here, the absorbent body 1 consists of an outer part 120a and an inner part 120b. The inner part 120b and the outer part 120a are permanently connected to each other. The absorbent body 1 is preferably produced in a multi-component injection molding process. The absorbent body 1 can also be made of more than two materials or only one material.

The absorbent body outer part 120a is made of a soft material. In particular, the mouthpiece 117 and the lip support 119 should as possible the shape and hardness a nipple correspond. Preferably, the outer part 120 a of the absorbent body 1 in the transition region of the lip support 119 to the mouthpiece 117 has a greater wall thickness than the mouthpiece 117, so that this sensitive and fracture-prone area is reinforced.

The FIGS. 2 and 2 The head 2 serves for receiving and positioning of the absorbent body 1 and the milk transfer into the absorbent body 1. it has substantially the shape of a cap for a bottle with a threaded sleeve 203 with internal thread 201 and one at the Cap integrally molded distributor head or head 205 on. The cap has a threaded ring or the threaded sleeve 203 final cover or support surface 204. From this support surface 204 rises a neck or a cylindrical portion 206 and the above-mentioned head portion 205, which is configured here substantially conical. Its outer wall or outer surface is identified by the reference numeral 211. It serves as a milk channel closure wall in this example. The transition from the neck 206 to the head portion 205 forms a sealing surface 210. The neck itself can also form a cylinder seal with its cylinder wall.

As the FIGS. 3a to 3d show, the receiving head portion 205 is preferably in the form of a body of revolution, in particular the shape of a ball, a flattened ball, a cone, a drop, a cylinder or a combination of these forms. Other shapes are possible.

In the receiving head 2 is a leading to the bottle interior connection or inlet channel 207, which leads via at least one distribution or connection channel 208 to the outer surface of the receiving head 2, wherein at least one opening or channel is present.

There may be provided a plurality of connection channels 208 and thus outlets. The connecting channels 208 preferably open into at least one distributor outlet or distribution channel 209, which is preferably designed as an annular channel on the outer surface of the receiving head part 205. The distribution channel 209 runs preferably at a constant height about the head portion 205. However, it can also be arranged one above the other several channels.

A ventilation opening 212 connects the interior of the bottle with the ventilation valve 102, which in FIG. 4 is shown. This can be done for example via an inlet channel 207 of the recording head 2 or directly.

The absorbent body 1, in FIG. 1 * The rubber-elastic inner part 120b, is slipped over the receiving head portion 205. In the state mounted so now is the absorbent body 1, as in the FIGS. 1 and 1 * is shown against the support surface 204, the cylindrical portion 206 and the outer surface or wall 211 of the receiving head portion 205 at. The seal and fixation of the absorbent body 1 takes place on these surfaces. The recess of the absorbent body 1 or its inner wall defines a sealing surface 115, which is particularly suitable for use in the art FIG. 4 is shown. This substantially spherical or the shape of the receiving head portion 205 adapted sealing surface 115 tapers down to the bottleneck. It proceeds in a holding surface 106 extending approximately perpendicular to the longitudinal axis of the absorbent body 1 in the form of a parapet, followed by a constriction in the form of a cylindrical neck which forms a cylinder seal 105. Subsequently, the recess widens again and extends in cross-section obliquely outwards. In this area, said ventilation valve 102 is arranged in the form of a circumferential lip.

The underside of the absorbent body 1 is preferably formed flattened and forms a support 101. The support and positioning relative to the receiving head 2 and the Saugnippelaufnahme carried by this edition 101, the cylinder seal 105 and by the support surface 106th

The capillary milk channels 114 of the teat communicate with the distribution channel 209 as will be shown below Outside surface 211 of the receiving head portion 205 closed.

These milk channels 114 and milk chambers 109 are associated with FIG. 4 and 5 described in more detail. In the embodiment described here, they are in the inner wall, respectively. integrated in the sealing surface 115 of the absorbent body. However, they could also be arranged wholly or partly in the outer wall of the receiving head 2, in particular of the head part 205.

The milk channels 114 and milk chambers 109 are preferably distributed uniformly over the circumference of the recess of the absorbent body 1. They preferably extend along the dome-shaped recess or inner side 115 from a lower region, which in the mounted state preferably extends approximately or completely to the annular channel 209 of the receiving head 2, toward a milk collection or milk outlet channel 116, in which they preferably open or in whose area they end. Preferably, the milk channels 115 terminate above the annular channel 209 and below the outlet channel 116.

The milk chambers 109 may be located at the beginning, at the end or anywhere in a milk channel 114. Each milk channel 114, only a part thereof or none may be provided with one or more milk chambers 109.

The channels 114 and milk chambers 109 may have different shapes. The chambers 109 preferably form pockets. The channels 114 and the chambers 109 may for example be rectilinear, curved or thread-like, as shown in the Figures 5 . 5a, 5b and 6a to 6d is shown. They can run individually or be connected to each other via further channels. Likewise, the channels 114 may be integrated partially or completely instead of in the absorbent body 1 in the receiving head 2, in particular in the receiving head part 205. The total cross-sectional area of all milk channels 114 is different depending on the use for infants of different ages.

The milk channels 114 and milk chambers 109 are open in the longitudinal direction of the suction nipple to one side, i. they are merely depressions or grooves in the absorbent body 1 and form no counterpart, i. without the pickup head 2, no closed channels. These openings are produced by manufacture and are closed with the outer surface 211 of the receiving head part 205, which acts as a milk duct closure wall.

The milk channels 114 form capillaries through which milk flows under vacuum. The geometric shape, width and depth paired with the right Shore hardness of the rubber allow a natural and "breast-close" suction and milk flow behavior.

The milk chambers 109 are used primarily for the visual monitoring of the desired air-free milk flow.

The sealing surface 115 of the absorbent body 1 serves on one side for separating and sealing the milk channels 114 and milk chambers 109 with each other and on the other side as a closure between the inlet channel 207 and the milk supply and the outlet channel 116. The outlet channel 116 collects the milk from the Milk channels 114 and forwards them to the milk outlet 123 on. The outlet channel 116 consists of at least one channel.

As in FIGS. 9 and 10 can be seen, the nipple tip is sucked into the mouth and squeezed by the suction function. The mouthpiece lengthens and, by the deformation of the lip support 119, the mouthpiece reaches far into the baby's mouth. By the axial movement of the mouthpiece 117, the sealing surface 115 of the absorbent body 1 lifts from the milk channel closure wall 211, ie the outer surface of the receiving head 2 and thus exerts a vacuum on the milk channels 114. The higher the vacuum generated, the more the milk flow is favored. As soon as the baby reduces the vacuum, the teat moves back to its normal position and interrupts the flow of milk. FIG. 9 shows the closed milk passage or the closed valve, if there is no vacuum and thus no milk flows. FIG. 10 shows the open milk passage or the open valve during the suction phase.

As in FIG. 7 can be seen, the ventilation of the bottle interior is carried out by the venting sealing lip 102, which in a Unterduck in the bottle 3 takes in outside air. The air flows via the air inlet opening 104 to the ventilation sealing lip 102. The ventilation sealing lip 102 allows the air to flow in only one direction. An opening between the vent seal lip 102 and the vent opening 212 connects the interior of the bottle with the nipple, with a negative pressure in the bottle flowing air into the bottle.

With a possible overpressure in the bottle 3, the ventilation sealing lip 102 is pressed against the support surface 204 and prevents leakage of air or liquid.

FIG. 8 shows a variant of the recording head 2. Here, the receiving head portion 205 and the threaded ring 203 is formed in two parts. The threaded ring 203 corresponds approximately to the known threaded rings for suction bottles. The absorbent body 1 is guided by this threaded ring 203 and is held by him on the bottle. The receiving head part 205 is pushed into the recess of the absorbent body 1 and held in a form-fitting manner therein.

In an exemplary embodiment, as in FIG. 11 is shown, a safety device is additionally provided, which forms an important functional unit. It is about preventing a possible defect that could harm the baby. It is a defined vulnerability built in, which should tear after a certain aging respectively after a certain use, so that the defect is perceived by the mother, before a part of the nipple detaches and the baby can swallow this detached part or stuck in the neck remains.

The safety device consists in this example of a predetermined breaking point 118, which is arranged in the absorbent body 1 in the transition region from the mouthpiece 117 to the lip support 119. This area is the most moving zone on the teat.

At this predetermined breaking point 118 is located on one side of the absorbent body 1 a defined reduction in wall thickness, so that after a certain aging not the whole nipple ruptures, but only on one side of a leak. Combined with it can be done by eccentric or staggered arrangement of the outlet channel 116, a one-sided weakening of the nipple. Thus, the target break point 118 is additionally supported. Thus it can be prevented that any part of the nipple peels off and can be swallowed. The teat rather tears at a certain point, respectively is leaking.

This predetermined breaking point 118 can also be used with other teat nipples, in particular the conventional hollow teat nipples.

The inventive suction nipple allows the most natural possible suction.
