Abstract

The invention relates to a teat for feeding bottles, consisting of a receiving head (2), produced from a dimensionally stable material, and a rubber-elastic suction element (1), produced from a rubber-elastic material. An entry channel (207) leading to the interior of the bottle and channels (208, 209) leading from there to the outer surface of the receiving head (2) are configured in the receiving head (2). The suction element (1), in an initial position, elastically and sealingly rests on at least one section of an outer surface (211) of the receiving head (2). Milk ducts (114) are located in the contact area between the suction element (1) and the receiving head (2) and communicate on the one end with the channels (208, 209) of the receiving head (2) which lead towards the outlet channel (116) in the mouthpiece (117) so that, when a vacuum is produced in the mouthpiece (117), milk can flow from the feeding bottle through the milk ducts (114) to the outlet channel (116), the suction element being returnable to its initial position and the flow of milk being interrupted when there is no vacuum. The teat according to the invention thus imitates the natural flow of breast milk.

Description

Suction nipple for milk bottles

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

BestätigungsKppIt 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 Bl, 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-part suction nipple 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 suction nipple and an intermediate plate to be arranged between bottle and nipple. This intermediate plate has capillaries to regulate the flow of milk.

GB 2 370 787 discloses a feeding 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 respectively 18 and 19. The erfmdungsgemässe teat for milk bottles has a Aufhahmekopf of a dimensionally stable material and an absorbent body of a rubber-elastic material. The receiving head is formed as the core of the teat and the absorbent body can be folded over the receiving head. In the receiving head leading to the bottle interior inlet channel and at least one emerging from this to the outer surface of the receiving head channel are provided. The absorbent body has a mouthpiece and an outlet channel for milk extending therein, so that milk can flow from the milk bottle into the outlet channel when negative pressure is generated in the mouthpiece. The absorbent body lies with an inner side in a basic position elastically sealingly against at least a portion of an outer surface of the receiving head. In this contact region of the absorbent body with the receiving head there are milk channels which communicate with the at least one channel of the receiving head and which lead in the direction of the outlet channel running in the mouthpiece, so that milk produced from the milk bottle through the milk channels in at hu mouthpiece the outlet channel can flow, which can be moved back to its normal position without negative pressure of the absorbent body and the milk flow is interrupted.

Preferably, 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

Preferably, the milk channels are formed 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, the suction nipple for milk bottles on a Aufhahmekopf 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 and a mouthpiece a running in it Having outlet for 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 against at least a portion of an outer surface of the Aufhahmekopfes. 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 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 a further embodiment of the invention, the teat for milk bottles on a receiving head of a dimensionally stable material and an absorbent body 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 and a mouthpiece having a milk outlet passage therein, so that milk can pass from the milk bottle into the outlet channel when the negative pressure generated in the mouthpiece, wherein the absorbent body in a basic position with an inner surface elastically abuts against at least a portion of an outer surface of the Aufhahmekopfes, and wherein in the receiving head is provided for the bottle interior leading inlet channel. This nipple is characterized by at least one channel, which is provided in the receiving head and which exits the inlet channel to the outer surface of the receiving head in the contact area of the absorbent body, so that when generated in the mouthpiece negative pressure milk from the milk bottle can flow through the milk channels into the outlet channel, without Low pressure of the absorbent body is moved back into its normal position and the milk flow is interrupted.

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 Aufhahmekopfes 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 suction nipple 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 erfmdungsgemässe 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 figures 1 and 1 show schematically *, the system consists of a suction body 1 made of rubber-elastic material, for example made of silicone, and a form of a receptacle for the absorbent body 1 forming dimensionally stable or rigid Verteilerkopf- or receiving head 2, here with an integrated threaded flange or threaded ring 203 for releasably ^' screwing the recording 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 above-described parts I ₅ 2, 2 '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 nipples and is modeled on the nipple of a human mother's breast. It 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 shown in FIG. However, it can also be made in several pieces, in particular in two parts, as shown in FIG. 1 *. 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 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 larger wall thickness than the mouthpiece 117, so that this sensitive and fracture-prone area is reinforced.

Figures 2 and 2 * show the distribution or recording head 2. The head 2 serves to receive and position 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 an integrally formed on the cap header or head 205 on. The cap has a threaded ring or the threaded sleeve 203 final cover or support surface 204. From this bearing surface 204 rises a neck or a cylindrical portion 206 and the above-mentioned head portion 205, which is designed here substantially spherical. 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 FIGS. 3 a to 3d show, the receiving head part 205 preferably has the shape of a body of revolution, in particular the shape of a sphere, a flattened sphere, 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 connection channels 208 preferably open into at least one

Verteüerauslass or distribution channel 209, which preferably as an annular channel on the

Outer surface of the receiving head portion 205 is formed. 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 bottle interior with the ventilation valve 102, which is shown in Figure 4. 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 part 205. In the state thus mounted, the absorbent body 1, as shown in FIGS. 1 and 1 *, abuts against the support surface 204, the cylindrical part 206 and the outer surface or wall 211 of the receiving head part 205. The seal of the absorbent body 1 or its inner wall defines a sealing surface 115, which is shown in particular in FIG. 4. This substantially spherical or the shape of Aufhahmekopfteils 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 suction nipple communicate with the distribution channel 209. As will be shown below, the milk channels 114 that are open inwardly and any milk chambers 109 that are present are separated from the outside wall or the bottom Outside surface 211 of the Aufhahmekopfteils 205 closed. These milk channels 114 and milk cartoons 109 will be described in more detail in connection with FIGS. 4 and 5. In the exemplary 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. Aufhahmekopf 2 and / or absorbent body 1 may also be formed without milk channels 114 or capillaries and be used only as a pure valve function in connection with vacuum.

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 domed recess or inner side 115 from a lower region, which in the assembled 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 FIGS. 5, 5a, 5b and 6a to 6d. They can run individually or be connected to each other via further channels. Likewise, the channels 114 may be partially or completely integrated instead of in the absorbent body 1 in the receiving head 2, in particular in the Aufhahmekopfteil 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 on one side, ie they are only depressions or grooves in the absorbent body 1 and form no counterpart, ie without the receiving 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 can be seen in Figures 9 and 10, the nipple tip is sucked into the mouth and pressed together 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 when there is no vacuum and thus no milk flows. FIG. 10 shows the open milk passage or the opened valve during the suction phase.

As can be seen in FIG. 7, the ventilation of the interior of the bottle takes place through the ventilation sealing lip 102 "which, in the case of underpressure in the bottle 3, introduces external air. The air flows via the air inlet opening 104 to the ventilation sealing lip 102

Ventilation sealing lip 102 allows the air to flow in one direction only. An opening between the venting sealing lip 102 and the ventilation opening 212 connects the

Bottle interior with the nipple, with a negative pressure in the bottle to allow air to flow 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.

Figure 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 a preferred embodiment, as shown in Figure 11, 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.
