Embodiment Construction

[0019] Referring first to Figure 1, a teat 10 for use with a feeding bottle includes a teat portion 12, a base portion 14 and an areola portion 16 therebetween. A flange 18 extends from the base of the base portion to enable attachment to a feeding bottle (not shown) in any suitable known manner. The base portion may also include any suitable type of one-way inlet valve such as an integrally molded duck-bill valve (not shown). The teat is circularly symmetrical about an axis A passing through the center of the teat.

[0020] The areola portion 16 includes a flexion region 20 comprising three grooves or flexion grooves 22 extending around the inner surface of the areola portion which effectively form mutually parallel / concentric circles about the axis A. Thinned area and thus around the teat part. The flex region 20 is generally disposed between a transition region 24 separating the base portion 14 from the areola portion 16 and a transition region 26 separating the areola po...

Abstract

According to a first embodiment, a nipple for a feeding bottle or a soother comprises a base portion, a teat portion, an areola portion and a flex region allowing flexing of the teat portion towards and away from the areola portion. According to a second embodiment, a nipple for a feeding bottle or soother is provided with a helical flow formation on the inner face of the teat, which allows continuous flow of liquid even when the teat collapsed via the helical flow path which allowing extension at the teat, in particular rotational or torsional extension.

Description

technical field [0001] The present invention relates to a teat, in particular to a teat or nipple for a feeding bottle or a soother. Background technique [0002] A variety of teats are known which are designed to mimic a human breast when manipulated. A known teat comprising a stem and a base is described in US 6645228 . The base has a bulbous region and an aerola region from which the stem protrudes. The bulbous area has an upper area with a tapering wall which acts as a spring element so that when the baby sucks on the teat, the areola area and stem move back and forth relative to the bulbous area. [0003] This structure has various problems. The movement of the areola region and stem relative to the bulbous region does not realistically simulate the movement of a human breast during sucking. Furthermore, since the tapered wall region provides flexibility, the amount of flex and where the flex occurs is ambiguous and unpredictable. [0004] A second known teat, desc...
