DE4131996A1 - Teat for baby's feeding bottle - has outlet formed by slit which is self-sealing when not in use - Google Patents

Abstract

The teat for a baby's feeding bottle is made from a material which can be easily elastically deformed. The teat (1.1) has an insert (2.1) which enables it to be fastened to a bottle with a screw thread neck. The end of the teat has a transverse slit (1.2) which is self-closing when the teat is not in use but opens automatically when the teat is gripped between the baby's lips. The teat can also be fitted to a bottle which is normally sealed by a crown cap. USE/ADVANTAGE - Teat for baby's feeding bottle which is self-sealing when not in use.

Description

The invention relates to a teat with leakage protection, preferably for babies and toddlers Use on beverage bottles and water bottles with an adapter on bottles with the same thread However, slope of different diameters and vessels with crown cork closure, the is preferably intended for use in travel.

The object of the invention is a simple and safe to clean, break and shatterproof To define the baby sucker, which is provided with a leakage protection and a roll-off protection, d. H. self-closing when not in use, and rolling further if the container falls over preventive roll protection. For use on standard beverage packaging, (Beverage bottles), which is particularly suitable for use in travel.

Baby suckers are known which are provided with adapters for attachment to bottles. Disadvantages of these suction cups are
- That the usable vacuum cleaner consists of several parts that both require an increased cleaning effort, and can be easily lost.
- That when the bottle falls, the contents can leak.
- That - the bottles can roll on as they fall on the surface.
- That the fastening threads do not fit different thread diameters from different manufacturers.
- That an attachment to beverage bottles with crown cork closure is not possible.

The solution according to the invention provides for a suction device to be provided with a leakage protection which is in the Area of the suction opening arranged, prevents the bottle from leaking. The leakage protection is opened by squeezing the suction area during the suction process and allows the appropriate use.

The invention is described using several advantageous exemplary embodiments and in sketches shown.

The leakage protection is realized in that there is a valve in the front area of the suction device is formed that an inward-facing area that is slotted and in In the idle state the interior closes elastically and forms a check valve. By pressure from the  The internal force increases and closes the interior up to the deformation limit the material of the sucker.

The valve only opens when used as intended, when the vacuum cleaner is in the front area is compressed and forms an elastic opening, which immediately Pressure closes again.

Figure 1 shows a suction cup in longitudinal section. The suction cup is made of two vulcanized rubber components, a threaded ring number. 2.1 and from a material of greater Shore hardness, and a suction part, no. 1.1 made from a material of lower Shore hardness that is vulcanized together, or from similar plastic components. Instead of rubber compounds, silicone rubber can also be used for the components. The advantage of this material is the better durability and the higher chemical resistance.

The suction slit, no. 1.2 which is produced by cutting a slot after vulcanization, in an area turned inside out. The suction slot is closed in the idle state, the closing force being increased within the limits of the material with increasing internal pressure in the vessel. The suction slit only opens when the suction area is pressed properly during the drinking process and opens the opening.

Another advantage of this design is that the suction cup due to its simple geometry and closed surface is easy to clean and also due to the high deformability severe deformation is not at risk of breakage or splintering.

Figure 2 shows an adapter with adjustable thread diameter and segmented thread. The roll-off protection is implemented by the shape of a polygonal outer contour, which is attached to the cover surface by means of webs. The polygonal outer shape prevents the bottle, which is provided with the adapter, from rolling over and falling when it falls over. The thread segments Fig. 2, No. 2.3 are attached to the surface areas of the polygon Figure 2, no. 2.2 molded on the roll-off protection. Thanks to the open structure, these components are also easy to clean thoroughly. The production is preferably made of hard rubber, production of or, for example, ABS plastic.

On the inside of the polygonal surfaces of the adapter there are thread segments Fig. 2, no. 2.3 molded or installed, which are spring-loaded due to the elasticity of the material of the polygon segments, the thread segments adapt when screwing onto the vessel, the thread turns of the segments into the thread on the vessel. This makes it possible to compensate for larger diameter differences (approx. 2.5 mm in the version shown) on the vessel thread with approximately the same thread pitch.

Figure 3 shows an adapter as in Figure 2, but with a holder, Figure 3, no. 3.6 m, for attaching standard suction cups.

Figure 4 shows the suction cup with an adapter for crown cork closures. The adapter consists of the crown cork closure contour of the bottle Fig. 4, no. 4.9 overlapping, radially segmented locking lips, Figure 4, no. 4.8 . The locking lip segments, Figure 4, no. 4.8 . The locking lip segments, Figure 4, no. 4.8 , are formed as independent segments on the flat surface contour of the adapter or, like the thread segments, on the polygon contour of the adapter. For use, the adapter is simply pressed onto the closure contour of the bottle and snaps into place. The seal is provided by one or more resilient sealing lips, Figure 4, no. 4.7 causes, which are supported on the closure contour of the bottle and thereby center the adapter while sealing at the inner edge of the bottle or the outer contour. Depending on the materials used for the production, the suction cup is vulcanized with the adapter, connected by means of a joining or adhesive technique or attached to the adapter contour.
