Description

teats

The invention relates to a bottle nipple with a connecting flange having base portion, in which the bottle nipple is circular in a plane perpendicular to a longitudinal axis cross-section, in essence, a lip abutting portion and an opening into a suction tip Nippelab ^¬ section, with the bottle nipple perpendicular in the lip abutment portion ^¬ has right to its longitudinal axis a deviating from a circular cross section with a longitudinal axis and a shorter compared to the longitudinal axis transverse axis.

Bottle teat, which are substantially circular in a lower base portion, to be connected in a simple manner and substantially to a usually circular bottle mouth, which, however, subsequent to this base portion having a non-circular cross-sectional shape, so that a special orientation of the bottle sucker in the use of which is predetermined, namely an orientation in which the longitudinal axis of the bottle nipple extend substantially in the direction of longitudinal extension of the lips or of the mouth of the baby using the bottle nipple are basically known.

Thus, for example, FR 2 854 322 B discloses a bottle nipple with such a form deviating from a circular shape above a base section.

Such bottle nipple have the particular advantage that a bending of the bottle nipple to a normally concave ge ^¬ curved outer surface of the bottle nipple in Lippenanlagebe- is rich possible relatively simple, that is, the bottle nipple has for pivoting about an axis extending in the direction of the longitudinal axis axis or in Transverse thereto, ie in the direction of the transverse axis, a relatively high flexibility. Such bottle suckers are due to their cross-sectional geometry but often comparatively inflexible formed perpendicular thereto, so that a swinging in particular of the nipple portion senk ^¬ right to the transverse axis is only partially possible. Various Flaschensau ^¬ ger are already known from the prior art to be with which an increased flexibility of the bottle ^¬ teat, in particular, the nipple and / or the Lippenanlage--section, is achieved.

From DE 3241845 Al a bottle sucker is known, which has in the shaft region in the manner of a concertina several reciprocating circumferential recesses.

From WO 2013/144624 AI another bottle sucker is known, which has a circumferential recess in a subsequent to a fastening ^¬ supply flange portion of the bottle sucker on ^¬ .

Also in DE 102015118252 Al a bottle sucker is shown, which has adjacent to the Saugerflansch a circumferential retracted area 8.

Thus, a suction member with the outside ring-shaped ^¬ circumferential shoulders or ribs is known from US 2,709,434, which comprises an annular weakened areas with reduced wall thickness ^¬. However, this is to be a seen in cross section perpendicular to the longitudinal axis over the entire height Rotati ^¬ onssymmetrischen teat, so that extending the in a plane perpendicular to the longitudinal axis, the peripheral wall thickness reduction, as expected, results in a substantially rotationssymmet ^¬ innovative bending behavior of the bottle nipple.

From US 5,190,174, another is the total amount Rotati ^¬ onssymmetrisch executed known bottle nipple having perpendicular to the longitudinal axis circumferential wave-shaped recesses to form a bellows-shaped portion for increasing the flexibility in a plane.

Likewise, US Pat. No. 4,505,398 discloses a bottle nipple which is rotationally symmetrical in the lip contact area and in which a wavy cross-sectional shape under the lip contact area has been formed to form a bellows-type section in order to increase the flexibility of the bottle nipple in this area. From WO 2013 / 150460A1 a bottle nipple is further known, which has distributed over the circumference arranged material weakenings, so that the bottle nipple between a collapsed position in which the nipple portion is lowered and the bending portion is substantially convex ge ^¬ curved, and a extended position of the nipple portion, in which the bending portion is configured in sections plan, can be transferred.

Children often carry out stormy or hek ^¬ tische movements when eating, which makes it difficult for the feeding parent to keep the bottle nipple centered to the mouth. Food intake is the greatest satisfaction for the baby and should therefore work well and satisfactorily. The aim of the present invention is therefore in a bottle sucker of the type mentioned, ie in a different from a Lipanlageabschnitt of a rotationally symmetrical shape bottle nipple, increased flexibility of the nipple ^¬ section substantially in the direction of the longitudinal direction of the bottle nipple in Lipanlageabschnitt or in Längserstre- ckungsrichtung to achieve the mouth opening in a state of use. This is intended in particular to increase the comfort for the baby when eating.

This object is achieved by the bottle nipple with the features of claim 1. Preferred embodiments are indicated in the dependent claims.

For the purposes of this disclosure, the location and direction information, such as "top", "bottom", etc., refer to the intended use state of the bottle sucker, if it is mounted in an upright baby bottle, ie at ei ^¬ ner vertical orientation of the longitudinal axis the bottle sucker.

According to the invention, there is provided between the base portion and the lip abutment portion an increased flexibility relative to the base and the lip abutment portion Biegeab ^{¬ section} , wherein the bending portion has a circumferential over the circumference recess in the form of a recess and / or has a smaller wall thickness than in the adjacent to the recess sections, so that the bottle sucker has an axis extending substantially in the direction of the transverse axis axis compared to an identically designed bottle suction without depression increased flexibility for pivoting the Lippenanlage- and nipple section.

Accordingly, the bottle sucker invention has a umlau ^¬ fende depression, so that in addition to the already given flexibility in a Verschwenkungsrichtung in the direction of the transverse axis also increased flexibility for pivoting the Lippenanlage- and Nippelabschnitts in the longitudinal direction of rotati ^¬ onsasymmetrisch trained lip abutment section is achieved. Thus, despite the rotationally asymmetrical configuration, a bottle nipple can be achieved, which enables a simple adaptation of the orientation of the lip system section and thus also of the nipple section in use both in the longitudinal and in the transverse direction. This improves the comfort of a baby or toddler using the bottle nipple.

To an increased flexibility of the bottle nipple in the formed under ^¬ half of the lip abutment portion bending portion to achieve, it is favorable when the recess along a cutting and / or contact line or surface ei ^¬ nes imaginary cone runs substantially with the bottle nipple, wherein a tip of the imaginary cone on the longitudinal axis in an inclusive the sow ^¬ gerspitze and adjacent portion is disposed at the suction tip, and said cutting line extends adjacent to or coincident with a tangential line of contact of the ge ^¬ covered cone and the bottle nipple. In this way, a reduction in the stability of the bottle nipple is achieved precisely in an area in which the forces causing a pivoting of the nipple tip, which initiates a baby using the bottle nipple, open.

In such an embodiment, there is thus a profile of the depression, which has a course deviating from a cross-sectional plane perpendicular to the longitudinal axis of the bottle nipple. Due to the rotationally asymmetric shape of the bottle nipple results in a along an imaginary Ke- gels extending recess a recess which is higher in the longitudinal axis in a side view, as in a running through the transverse axis cross-sectional area. Thus, in vertical cutting planes passing through the longitudinal axis, two peaks of the depression result, whereas in a vertical cutting plane passing through the transverse axis, two troughs of the circumferential depression result. Consequently, the course of the depression differs fundamentally from the course of known indentations or material weakenings in a cross-sectional area running perpendicular to the longitudinal axis, as known in the prior art from rotationally symmetrical bottle suckers.

The course of the recess is chosen such that the bottle nipple for pivoting the Lippenanlage- and nipple sections about an axis extending substantially in the direction of the transverse axis in the bending section has a higher flexibility ^¬ than an axis extending in the direction of the longitudinal axis. Advantageously, this results in a rotationally asymmetric bottle aspirator, which due to the increased flexibility in the direction of the longitudinal axis due to the recess in Biegeab ^{¬ section} easy pivoting of the nipple section made ^¬ light. In addition, however, a pivoting of the nipple portion in a vertical direction thereto, ie in the direction of the transverse axis is possible, in which direction the pivoting takes place primarily by bending the bottle nipple in the area of the lip contact section. Preferably, therefore, a bottle nipple can be achieved in which substantially the same bending forces are required for pivoting the lip contact and nipple sections about the longitudinal and transverse axes; that is, despite the Rotati ^¬ onsasymmetrischen embodiment of the bottle nipple, the bottle nipple, a substantially rotationally symmetrical

Panning behavior of Lippenanlage- and Nippelabschnitts on.

In order to achieve a particularly high flexibility, it is advantageous ^¬ way, if the wall thickness in the region of the recess by at least 30%, preferably at least 50%, is less than in a region adjacent to the recessed portion.

Furthermore, it is for the design of a defined bend line, which bending of the bottle nipple in the bending portion beneficiaries ^¬ kind, advantageous if the outer surface of the bottle nipple is concavely curved in the region of the recess, wherein the concave curvature has a circumferential crest line. About the crest line is thus defined a kind of crease line along which the bottle nipple buckles upon application of forces which seek to pivot the teat tip from a substantially coinciding with the longitudinal axis of the teat position.

If an outer surface of the bottle ^{sucker is} convexly curved in an area adjacent to the recess above and / or below, an increased stability results due to the curvature in the area adjoining the recess, so that it is reliably ensured that buckling of the flap occurs ^¬ sniffer is achieved in the recess and not undesirably in an area adjacent to the depression.

With respect to a particularly high Saugkomforts is fiction, ^¬ provides that the bottle nipple is designed Location Area rotationally asymmetric not only on Lippenan-, but that the bottle nipple having a deviating from a circular shape cross-section with a longitudinal axis and a shorter compared to the longitudinal axis transverse axis in the nipple portion. A derarti ^¬ ge configuration is particularly favorable from an ergonomic point of view for receiving the Nippelabschnitts- and lip bearing section in the mouth or the mouth of the baby.

Furthermore, it is favorable for stiffening the bottle nipple in an area adjacent to the recess, when the bottle nipple has, above the recess and adjacent to the recess, an inwardly projecting, preferably bead-like material reinforcement over the entire circumference. Thus, it is further ensured that the bottle ^spout does not buckle in an area in which this is not desired at all.

In order to achieve a more effective over the entire circumference ^{essen¬ ¬} springy storage of the bottle nipple, it is advantageous if the bottle sucker under the bent portion in a conventional manner has a Querschnittsver tion, which is followed by the connecting flange.

In this cross-sectional connec tion, an inwardly projecting collar of a mounting ring can be added in an advantageous manner, so that there is an intimate connection between bottle sucker and mounting ring in the connection to a baby bottle.

Unlike in the area of the depression, however, no buckling of the bottle nipple is provided with corresponding load during use in the area of the cross-sectional tapering. Accordingly, it is advantageous if the bottle ^{nipple has} a substantially constant wall thickness in the region of the cross-sectional tapering.

When the bottle nipple continuously has a concavely curved outer surface in a plane extending in the direction of the transverse axis cross-sectional area in the lip abutment portion at least in sections, preferably, the concave curved externa ^¬ ßere surface of the bottle nipple favored in the lip abutment portion swinging out of the nipple portion into the direction of the transverse axis, that is perpendicular to that of Direction in which an increased flexibility is achieved in particular with the recess according to the invention.

Unless having bottle nipple in a plane extending in the direction of the longitudinal axis of cross-sectional area in the lip abutment region at least in sections a planar or convexly curved outer Oberflä ^¬ surface or the outer surface composed of a Kombina ^¬ tion of a flat and convex curved surface, this results in an increased stiffening of Fla ^¬ rule sucker in a pivoting direction about the transverse axis of Fla ^¬ rule sucker. Accordingly, it is in particular in such an embodiment of the bottle nipple of advantage if the rule Fla ^¬ sucker having a recess according to the invention.

With regard to a particularly good Saugkomforts, which is based on the design of the maternal nipple, it is of Advantage, when the outer surface of the bottle sucker in the nip ^¬ pelabschnitt both in a parallel to the longitudinal axis and the transverse axis extending cross-sectional area has a convexly curved ^¬ ge section.

For a particularly reliable connection of the bottle sucker with a fastening ring, it is advantageous if the connecting flange has a preferably circumferential groove on its upper side. In providing such preferably umlau ^¬ fenden groove may or may in the mounted on a baby bottle position one or more ribs, which are added at the bottom of an inwardly projecting collar are fastening ^¬ rings provided so that it in a form-fitting connection comes between the projecting ribs or a circumferential rib and the groove at the top of the connecting flange.

In order to achieve a particularly tight connection of the bottle nipple on ei ^¬ nen upper edge of a bottle opening, it is advantageous if the connecting flange has on its underside a circumferential, preferably one edge of an upper connection opening of a container correspondingly extending groove.

Furthermore, it is favorable for sealing the bottle sucker against egg ^¬ ner opening over an edge of a bottle when the connecting flange on its underside, preferably adjacent to the groove, has a downwardly projecting sealing lip.

The invention is explained below with reference to an illustrated in the drawings the preferred embodiment to which the invention should be by no means limitative, still in De ^¬ tail.

FIG. 7 shows a sectional view according to the line VIA-VIA in FIG. 5 along the longitudinal axis in the area of the lip area; FIG. and

8 shows the detail VIII according to FIG. 7.

FIGS. 1 and 2 each show perspective views of a bottle nipple 1 which, as can also be seen in particular from FIG. 3, can be subdivided into the following sections:

First, in a lower end portion, a base portion 2 is provided, which has a connecting flange 3. At the base portion 3 then connects a bending section 4. Above the bending section 4, a lip abutting portion 5 vorgese ^¬ hen at which the upper end portion of a nipple portion 6 connects, which opens into a suction tip. 7 The suction tip 7 has a suction opening 8 for a liquid passage.

As can be seen from the perspective views according to FIGS. 1 and 2 and from a comparison of FIGS. 3 and 4 and also in FIG. 5, the bottle nipple 1 is in its lower part Base section 2 is rotationally symmetrical, ie it has in a cross section perpendicular to its longitudinal axis 9 in wesent ^¬ union a circular shape.

Above the base section 2 in the area of the lip abutment section 5 and in the nipple section 6, however, the bottle nipple has an approximately elliptical cross section deviating from a circular shape in cross section perpendicular to the longitudinal axis 9, with a greater extension in the direction of a longitudinal axis 10 and one in comparison to the longitudinal axis of shorter extension in the direction of a transverse axis 11 (see Fig. 5).

Due to this cross-sectional geometry is obtained that the Fla ^¬'s teats without bending section 4 th a relatively good Flexverhal- during pivoting of the nipple portion 6 in the direction of the transverse axis 11 has, that is, at a pivoting of the suction tip 7 12 in the direction of arrow Here buckling the nipple 1 in the nipple portion 5-use depending on the application of pressure from the baby Flaschensau ^¬ ger a substantially around a bending zone. 13

However, due to the geometric design of the bottle nipple 1, the suction nipple 7 would have to be swiveled out in the direction of the arrow 14 (FIG. 3), without the bending section 4, because the outer surface of the bottle nipple 1 is in the region of the lip abutment. Section is essentially flat or slightly convex ^{ausgestal ¬} tet, so there is a stiffening in this area.

To improve the flex behavior of the bottle teat 1 on a pivoting of the suction tip 7 and the Lippenanlagenab--section in the direction of arrow 14, ie about an axis extending in the direction of the transverse axis 11 axis to favor, has the bottles ^¬ teat 1 on the bending section. 4

In the bending section 4, a recess 15 is provided, which - as shown in Fig. 6 - substantially along a

Section line or contact line of an imaginary cone 15a with the on the outer surface of the bottle sucker 1 in Biegeab ^{¬ section} 4 runs. In this case, a cone 15a, whose tip on the longitudinal axis 9 in a suction tip 7 enclosing and the suction tip 7 adjacent portion 17 is arranged. This portion 17 comprises, in particular a length up to 5 mm above and below the teat tip, in the illustrated embodiment, preferably the conical tip 2 mm disposed above ^¬ half of the suction tip. 7

The imaginary cone 15a is then placed in the bending section 4 below the lip abutment section 5 at a shallow angle on the outer surface of the bottle nipple 1, preferably substantially centrally over the extension of the bending section 1, so that a circumferential cutting line 15a results. The section line runs - unlike rotationally symmetrical bottle teat - with a depression for the purpose of increasing flexibility not along a perpendicular to the longitudinal axis 9 durau ^¬ fenden cross-sectional plane, but has - due to the asymmetric ^¬ embodiment of the nipple 1 in the bending section 4 - seen over the circumference rising and falling course. Due to the geometric configuration of the bottle teat 1 arising in the region of a vertical, down through the longitudinal axis 10-sectional area has two maxima 18a in the course of the Ver ^¬ deepening and in the direction of the transverse axis 10 two minima 18b, as shown particularly in the in FIGS. 6 and 6A shown sectional plane along the transverse axis can be seen.

About the circumferential recess 15 is thus due to the Geo ^¬ geometry of the bottle teat 1 is essentially a buckling of the bottle teat 1 when a force toward the direction of the arrow 14, ie about an axis extending at a pivotal movement of the nipple portion 6 and the lip engaging portion 5 in the direction of the transverse axis 11 Axis achieved, thereby a significantly improved bending behavior of the nipple 1 is achieved.

In order to simplify the buckling of the bottle sucker 1 in the region of the Biegeab ^{¬ section} 4 at pressure application in the nipple portion 6 and / or Lippenanlageabschnitt 5, the sucker in Lipanlageabschnitt 5 said recess 15, which is shown in Fig. 8 in detail. It can be seen that the bottle nipple 1 in the embodiment shown in the region of the recess 15 has a reduced wall thickness of about 0.6 mm to 1 mm, preferably of about 0.8 mm, where- gen the wall thickness in the lip abutment portion 5 is usually about 1.2 mm to 2 mm. In addition, the course of the wall la of the bottle nipple 1 on a recess 19, ie the course of the wall la of the bottle nipple 1 has in this Be ^¬ rich on a concave profile, which has a vertex 19a, which essentially serves as a bending line.

In order to prevent collapse of the bottle nipple 1 in a region adjacent to the Vertie ^¬ Fung portion 15 reliably, a bead-like, inwardly projecting reinforcing material 20 is provided in particular above the recess 15 °. In this area, the wall la of the bottle nipple 1 has an approximately 2 to 4 times greater wall thickness than in the region of the depression 15, so that the bottle nipple 1 does not yield at a pressure application in this area, but the desired buckling in the subsequent area the recess 15 is achieved.

Of course, the depression 15 can also be realized only via the geometric configuration, i. a concave recess 19, or by a groove-like material recess, i. Wandstärkenver üngung, be achieved on the outer surface of the bottle sucker 1.

In particular, in Fig. 6B is still apparent that in Basisab ^¬ section 2 a Querschnittsver tion 21 is provided, which on the one hand forms a resilient base for the entire angeord ^¬ Neten soother section and also for receiving ei ^¬ nes inwardly projecting collar 22 of a fastening ring 23 is used.

The fastening ring 23 can advantageously also have downwardly projecting webs 22a or a circular circumferential web 22a, which cooperates in the position connected to the bottle mouth 24 in a circumferential groove 25 arranged on the connecting flange on the upper side. Due to the positive reception of the web or webs 22a in the groove 25 thus a positive connection between the connecting flange 3 and mounting ring 23 is achieved.

Furthermore, the connecting flange 3 on its underside a circumferential groove or recess 26, in which an upper edge 24a of a bottle mouth 24, to which the bottle nipple 1 is attached, is received. This also results in a reliable, sometimes form-fitting connection of the Fla ^¬'s teat 1 on the bottle mouth 24th

With regard to a good seal of the connection between the fastening ring 23 and the bottle mouth 24, it is further advantageous if the connecting flange 3 of the bottle nipple 1 has a sealing lip 27 which circumferentially connects inside the lower circumferential groove 26 for receiving the edge 24a of the bottle mouth 24. Thus, a reliable connection of the bottle nipple into the bottle mouth 24 can be achieved in particular even with a snap connection between the fastening ring 23 and bottle mouth 24.
