Description

SUCTIONER TO DRINK DESCRIPTIVE MEMORY The invention relates to a bottle nipple made of an elastic material. Bottle nipples serve for the nutrition of infants and children. The known bottle nipples have a high suction nozzle and a circumferential edge to be fixed to a bottle opening of a bottle. drinking bottle Since the mounting edge has a larger cross-section than that of the suction nozzle a hollow transition area is present between the suction nozzle and the mounting edge and usually expands from the suction nozzle to the suction nozzle. Mounting edge In its final region, the mounting nipple has a drinking hole through which the liquid can exit A vent valve with a valve groove is inside the transition area The bottle nipple is fixed to the opening flange of the bottle to drink through a threaded ring For this purpose, the bottle nipple slides through the threaded ring until that the mounting edge comes to settle under an annular flange of the threaded ring The threaded ring is screwed onto a male thread of the drinking bottle, by whose action the mounting edge is sandwiched between the opening flange and the threaded ring It is also known to configure the venting valve by placing suitable channels in the seat range of the mounting edge on the opening flange of the drinking bottle. The child may attract liquid or other fluid food with which the bottle is filled to drink, by sucking the suction nozzle. This causes the food to come out through the drinking hole and a pressure balance takes place with the environment through the vent valve. The known bottle nipples have the disadvantage that they only allow a small flow of the food to be provided. If the drinking hole is built too large the liquid can flow out without suction work performed by the child. As a result, the child is not able to take food and the food may come out to spill. Furthermore, taking the food is restricted by the ventilation valve that limits the pressure balance. From WO 2004/013001 A2 a spill-proof drinking cup is known wherein the suction nozzle has a hollow part with parallel drinking grooves. When the user bites the outer walls of the suction nozzle, the interiors thereof urge the bottom of the hollow part, which will open the drinking slots disposed at the bottom of the hollow part. This spill-proof drinking cup is not suitable for use by infants and children because they are unable to open the slots to drink by biting the suction nozzle. Even more, this drinking cup does not support the natural suckling work of the infant or child.

Accordingly, it is the object of the invention to provide a bottle nipple made of an elastic material which allows a greater flow of the food to be provided without adversely affecting the natural suction process and which still prevents any unintentional spillage of food efficiently. The object is achieved by a bottle nipple having the characteristics of claim 1. Advantages of the bottle nipple are indicated in the dependent clauses The bottle nipple of an elastic material has - a hollow suction nozzle, a mounting edge circumferential for attachment to the bottle opening of a drinking bottle, - a hollow transition zone between the mounting edge and the suction nozzle, - at least one drinking groove oriented in the longitudinal direction of the suction nozzle and extends from the outside towards the inside of the suction nozzle to a region of bulging outer end out of the suction nozzle, and - at least one vent valve with a valve groove extending from the outer wall from the transition zone to the inner wall of the transition zone In the bottle nipple of the invention, the groove to drink in the suction nozzle ensures a greater flow of the food to be provided. This is the case when an individual drinking groove of appropriate dimensions exists because it allows a greater outlet than a drinking orifice Since the drinking groove is located in an end region bulging out of the bottle nipple, the attraction of food requires suction work In contrast to the state of the art, food traction does not imply that the bottle nipple is clamped. An adequate pressure balance is also possible through an appropriately sized valve groove. According to one aspect, the suction nozzle has at least two parallel drinking grooves The two parallel drinking grooves ensure a particularly large exit of the food to be provided when the child sucks the bottle nipple According to one aspect, the at least one drinking groove is rectilinear and / or corrugated and / or serrated Rectilinear grooves are particularly easy to manufacture when cutting mechanically. the bottle nipple The wavy or serrated drinking slots favor a particularly high output of the food to be provided because they can be configured within a small space of a particularly long efficient length The invention also encompasses designs wherein the drinking slot is rectilinear or crimped or serrated only in at least one sub-region and is another of the forms mentioned above or a different form in at least one other sub-region The invention encompasses designs wherein the suction nozzle is disposed centrally with respect to the mounting edge with one aspect, the suction nozzle is arranged eccentrically with respect to the mounting edge This favors a complete attraction of food from the drinking bottle when the bottle rotates to arrange the suction nozzle at the bottom This design is particularly ergonomically beneficial According to one aspect, the suction nozzle is of transverse section ersal that tapers to the outer end This specifically facilitates manufacturing and is particularly beneficial ergonomically This also applies to another aspect of conformity with which the suction nozzle is oval cross-section This also applies to an aspect where one side of the Suction nozzle that is closer to the mounting edge has a lower inclination from the nozzle axis than the side of the section nozzle that is further away and distant from the mounting edge Particularly for reasons of simple manufacture and ergonomics, in accordance with an additional aspect, the suction nozzle has a rounded portion toward the transition zone on the distal side of the mounting edge to prevent the bottle nipple from collapsing in the area of the rounded portion, the rounded portion and, selectively, the adjacent transition zone carries a rib in the interior According to one aspect, the area of nsition is in the form of a dome. This is also beneficial for reasons of easy manufacturing and ergonomics. According to one aspect, a circumferential constriction is present between the mounting edge and the transition zone. This stabilizes the bottle nipple around the constriction and prevents its excessive deformation that may prevent the attraction of food. According to an advantageous aspect, there are at least two ventilation valves to ensure a good pressure balance. According to one aspect, the vent valve is located in a depression of the transition zone. This particularly counteracts an unintentional leakage of feed through the valve groove. Furthermore, the protected arrangement of the vent valve within the depression favors uniform operation of the vent valve. According to one aspect, the depression is present at the outer edge of the dome transition zone. According to one aspect, the vent valve is located diametrically opposite the suction nozzle at the outer edge of the transition zone. This helps to ensure that if the suction nozzle is disposed at the bottom the vent valve will not be wetted with food so that a uniform pressure equilibrium is possible.

According to one aspect, the mounting edge has a mounting flange, this favors a sealing application of the mounting edge between the threaded ring and the opening flange of the bottle. According to a further aspect, the mounting flange has a circumferential projection on the inner edge The circumferential projection, in conjunction with a suitable threaded ring, prevents the bottle nipple from being inadvertently pulled out of the threaded ring Possible aspects of the bottle nipple with a protrusion or other thickened region and a Combined threaded ring are described in DE 197 39 911 C5 the description of which is incorporated in the present application to a certain degree According to a further aspect, the mounting edge is annularly circular Finally, according to one aspect, the teat bottle is made from natural rubber or silicone It is preferred that the bottle nipple be manufactured from one of the above materials However, designs are also incorporated herein which are made of various materials connected to each other. The bottle nipple is preferably made of natural rubber, for example in an immersion process with aluminum molds and a post-treatment and curing The slots for drinking and valves are preferably introduced by mechanical cutting. The invention will be described in more detail below with reference to the accompanying drawings. In the drawings: Figure 1 shows the bottle nipple in a vertical section; Figure 2 shows the same bottle nipple in a vertical section displaced by 90 °; Figure 3 shows the same bottle nipple in a plan view. The bottle nipple 1 has a hollow suction nozzle 2 which, by means of a hollow transition area 3, joins a mounting edge 4 for fixing the opening area of a bottle. The suction nozzle 2 is of an oval cross section tapering towards its external region 5 (see Figure 3). The side 6 of the suction nozzle 2 is closer to the mounting edge 4 has a smaller inclination from the nozzle axis having the opposite side 7 of the suction nozzle 2 which is more distant from the mounting edge 4. The side 7 of the suction nozzle 2 extends to end in a concave rounded portion 8 towards the transition area 3. The outer end region 5 of the suction nozzle 2 is bulged outward, i.e. it is domed. The outer end region 5 has there arranged two parallel grooves 9, 10 which are oriented perpendicularly to the sides 6, 7 of the suction nozzle 2. The grooves 9, 10 extend from the outer wall 1 1 to the inner wall 12 of the suction nozzle 2.

The suction nozzle 2 gradually passes over the transition area 3 Within the transition area 3 the nipple of the bottle 1 gradually expands to the largest diameter of the mounting edge 4 The transition area 3 has a circumferential outer edge 13 A circumferential constriction 14 is present between the edge 13 and the mounting edge 4 Within the area of the circumferential outer edge 13, a depression 15 emerges diametrically opposite the suction nozzle 2 disposed eccentrically with respect to the mounting edge 4 The depression 15 houses a ventilation valve 16 The vent valve 16 has a valve groove 17 The valve groove 17 extends from the outer wall 18 to the inner wall 19 of the transition area 3 The interior of the rounded region 8 has a rib 20 extending in parallel with the drinking slots 9, 10 The mounting edge 4 comprises a mounting flange 21 having a circular projection nferential 22 at its lower edge The interior of the bottle nipple 1 houses a cavity 22 extending from the opening 24 bordered by the mounting flange 4 through the transition area 3 and the suction nozzle 2 to the drinking grooves 9For use, the bottle nipple 1 is fixed, by means of a threaded ring that is not shown to a drinking bottle that is not shown and that is filled with liquid food. The fixing device is formed, for example, in the manner shown in Figure 4 of DE 197 39 91 1 C5 and the description of which is incorporated in the present application is explained in the relevant description of the figures. During the lure of food, the drinking bottle is held to cause the suction nozzle 2 to be oriented obliquely downward with the suction nozzle 2 located at the lower edge of the drinking bottle. The two drinking slots 9, 10 allow a particularly high flow velocity when the smaller one sucks the suction nozzle. The configuration and dimensions of the ventilation valve 16 also favor a pressure balance and, therefore, a high flow velocity.
