In the upper, nipple-like area 5 , a drinking hole 7 is arranged through which a drinking liquid or nutrient liquid can escape from the interior of the bottle body 3 .

The drinking teat 4 is in the embodiment shown in FIG. 1 via a screw ring designed as a fastening ring 8 with a bottle neck 3 A of the fla body 3 connected. The ring nut 8 has a substantially cylindrical portion 9 with an internal thread 10 which cooperates with an external thread 11 on the bottle neck 3 A. The ring flange 8 also has a central through hole 12 for the nipple 5 and the spout 6 of the drinking teat 4 and an inwardly projecting ring flange 13 , which serves to create an outwardly curved teat flange 14 of the drinking teat 4 . The teat 4 and the screw ring 8 are namely pre-assembled in a known manner such that the nipple 5 and the nozzle 6 are pushed through the through hole 12 of the screw ring 8 until the teat 4 with its sow gerflansch 14 on the underside of the ring flange 13 of the Screw ring 8 is present. In this preassembled state, the screw ring 8 is then screwed onto the external thread 11 of the bottle 2 with the teat 4 inserted.

The leakage protection 1 has a cap 15 as a shut-off means, which is attached from the outside in the area of the drinking teat 4 and prevents the flow through the drinking hole 7 by means of a pressing action on the drinking teat 4 . For this purpose, the cap 15 has a cap part 16 shaped in such a way that, when placed on the bottle 2 , it presses at least the upper, nipple-like area 5 of the drinking teat 4 in the longitudinal direction of the bottle 2 . The surface of the inner cap part 16 facing the teat 4 comes to rest against the nipple-like part 5 of the teat 4 in such a way that the drinking hole 7 is sealed off from the external environment.

According to a particularly advantageous embodiment of the leakage protection 1 with the cap 15 , the cap part 16 can be designed such that it has an opening 17 with a cavity 18 for receiving the drinking teat 4 in an end facing the contact area with the bottle 2 , the cavity 18 is delimited by an at least approximately cylindrical lateral surface 19 and a base part 20 which has a bulge 21 projecting into the cavity 18 .

According to the illustration shown in FIG. 1, the bulge 21 projects into the cavity 18 in such a way that, in a state placed on the bottle, the upper, nipple-like part 5 is displaced by the bulge 21 into the lower, spout-like area 6 of the drinking teat 4 is. The overall height of the cap can be smaller than the height of the drinking sucker in a state without a cap in order to save installation space. It goes without saying that the dimensioning of the cavity 18 and the Vorse hen and the shape of the bulge 21 , ie the United shift of the nipple 5 , are matched by the skilled person on the drinking teat 4 to be sealed so that damage to the drinking teat 4 can be excluded ,

In the embodiment shown in FIG. 1, the cap inner part 16 is surrounded by a cap outer part 22 which, in the state placed on the bottle 2 , encompasses a contact area of the bottle, here the mounting ring or screw ring 8 placed on the bottle neck 3 A, encompassing the circumference. The inner circumference of the Kappenau outer part 22 is so matched to the outer circumference of the screw ring 8 that these components form a plug connection with one another. The inner circumference of the outer cap part 22 can have any shape which also has the outer wall of the screw ring 8 , such as. B. circular or part circular.

In order to achieve a defined fit of the cap pe 15 on the bottle 2 or the screw ring 8 , the cap inner part 16 is arranged in the cap outer part 22 in such a way that it is placed on the face of the bottle 2 or the screw ring 8 on the end face on the surface of the screw ring 8 is applied.

In addition or alternatively, it can of course also be provided that the cap 15 with the screw ring 8 has a snap connection z. B. forms over grooves, or that the cap 15 via a screw connection with the contact area of the bottle 2 , here the screw ring 8 , is connected.

The inner cap part 15 and the outer cap part 22 are designed here as separate, pre-assembled components. In another embodiment, however, it can of course also be provided that the inner cap part and the outer cap part are made in one piece.

As can be seen from FIG. 2 and FIG. 3, the outer contour of the cap 15 can be shaped in a very different manner.

In the simplest embodiment, the cap 15 can have a cup-like outer contour, as shown in FIG. 2, optionally with a flattening on one side, or be modeled as in FIG. 3, all types of shaping, for. B. also in the manner of a character to offer. In a cup-like design as in FIG. 1, a recessed grip can also be provided on the outside of the base part 20 , which can serve, for example, to rest a thumb during a shaking process. In the same way, 15 gripping surfaces, e.g. B. corrugations can be provided, which facilitate the removal of the cap.

The execution shown in Fig. 1 to Fig. 3 form the leakage protection according to the invention provides a very simple is to use solution, since the cap 15 is inverted only in the type of an already previously ling bottles at Säug known lid via the drinking teat. 4 Then the bottle can be shaken who the z. B. for mixing ingredients in the bottle 2 . For administration to an infant, the cap 15 only has to be pulled off the bottle 2 or the screw ring 8 . The measures in Figs. 1 to FIG. 3 presented solution offers itself as a very advantageous transport protection, since to maintain the off-running protection no operation by an operator is required.

1 Further, the leakage protection according to FIG. To FIG. 3 is a highly cost-effective solution. Since it is also conceivable that the outlet protection 1 is retrofitted to an existing cap for a suction bottle by the cap inner part 16 in an already existing cap body is used.

FIGS. 4 through Fig. 6 show another exporting tion of the outlet cover 1 for a suction bottle 2, wherein a cap 23 is provided from ela stischem, rubber-like material here as a shut-off means which faces also in a contact region with the bottle 2 End has an opening with a cavity 24 for receiving the drinking teat 4 .

The cavity 24 is delimited here by a lateral surface 25 , which can be compressed in order to disconnect the drinking nipple 4 in a radial direction to a longitudinal axis of the drinking nipple 4 . In isolation, the cavity 24 of the cap 23 has no at least approximately elliptical cross-section without external force, as is indicated in a highly schematic manner in FIG. 5. When external force is applied, the cavity 24 is deformable in such a way that it has an at least approximately circular cross section, as can be seen in FIG. 6.

In order to implement a leak protection for the bottle 2 , the cavity 24 is dimensioned such that the upper, nipple-like area 5 of the drinking teat 4 can be inserted into the cavity 24 when it assumes its at least approximately circular cross-section under the action of force from outside. In this state, the cap 23 is placed on the ring suction device 4 . When the cap 23 is subsequently released, the cavity 24 deforms again against its elliptical cross-section and presses it in the radial direction to a longitudinal axis of the drinking teat 4 such that the flow through the drinking hole 7 is unconnected.

Thus, an operator compresses the cap 23 to the form suitable for deformation of the cavity 24 towards its kreisför-shaped cross-section 24 points on the outer contour of the cap 23 are at the outside of the cap 23 in the embodiment shown in Fig. 4 exporting tion oppositely disposed finger grips hen hen, which are designed as recessed grips 25 .

Also shown in FIG. 4 to FIG. 6 shown exporting approximately variant offers a cost-effective and reli permeable leakage protection both in a shaking of the bottle as well as a transport.

As can be seen from FIG. 7, the cap 23 can have any external contour, such as, for. B. the egg ner game figure, the opposite Griffstel len can be provided for example in the form of legs or arms of such a game figure.

Fig. 8 shows a simplified embodiment of the leakage protection 1 with a cap 26 made of elastic, rubber-like material, the outer surface of the cap 26 having a recess or a slot 27 extending in the longitudinal direction of the cap 26 is ausgebil det.

In this embodiment, the cap 26 is placed over the teat 4 to be clamped, the flow through the drinking hole 7 by means of a radially inward pressing force of an operator being suppressed.

FIGS. 9 and FIG. 10 show a further variant of the exporting approximately leakage protection 1 according to the invention, wherein in the region of the neck 3 Fla rule attachable A hinged lid 28 is provided here as a shut-off a. This hinged lid 28 has a lid part 29 , by means of which the upper, nipple-like part 5 of the drinking nipple 4 can be pressed in the longitudinal direction of the bottle 2 such that the drinking hole 7 seals against the surroundings abuts the lid part 29 . For attachment to the bottle 2 , the hinged lid 28 has a fastening device 30 , which has a clamping ring 31 , which is positioned between the fastening ring or screw ring 8 for the drinking teat 4 and the bottle body 3 , and a pivotable, tab-like holder 32 , which the Cover part 29 binds with the clamping ring 31 , includes.

The lid part 29 is formed like a disk as shown in Fig. 9 and Fig. 10 shown embodiment. Of course this may, however, also have a different outer contour, and optionally on its side facing the teat 4 facing surface a central Auswöl bung in the direction of the sealed teat 4 in ways.

Fig. 11 shows a further Substituted staltungsmöglichkeit of the discharge protection 1 according to the invention, said device here as a shut-off means a clamp 33 is used. This clip device 33 be made of elastic material and has a slot-like recess 34 , which is dimensioned such that with a corresponding expansion of the slot-like recess 34 by an operator at least the nipple 5 of the teat 4 in the slot 34 can be performed. If the force is interrupted from the outside, the leg-like regions 35 , 36 on both sides of the slot 34 move towards each other again, pressing them together in the radial direction to the longitudinal axis of the drinking teat 4 such that a flow through the drinking hole 7 is prevented , In order to simplify operation, corresponding gripping surfaces 37 , 38 are provided on the legs 35 and 36 of the clamp device 33 in the embodiment shown.

In order to avoid too much compression of the drinking teat 4 and possible damage to it, the slot-like recess 34 has a widening in the region provided for the clamping of the drinking teat 4, an expansion 39 which is adapted to the shape of the drinking teat 4 ,

This very cost-effective variant of the leakage protection 1 is also suitable both for shaking the bottle 2 and as a transport protection.
