Problems solved by technology

[0008]The disadvantage of the above solution is that the reliance on lip seals makes it susceptible to particles in the liquid that get wedged between these lips, causing undesirable risk of leakage

Embodiment Construction

[0024] The teat 10 shown in the drawing has a generally conventional teat 12 and only the teat portion which involves the vent valve shown in the drawing. Typically, a flange 14 surrounds the base of the teat 10 . The flange 14 acts as a sealing ring and, in use, is sandwiched between the top of the feeding bottle and an annular ring screwed on the mouth of the feeding bottle. The feeding bottle and annular ring are conventional so are not shown in the drawings.

[0025] The flexible material from which the teat and vent are made can also be conventional, typically silicone or elastomeric, which can withstand chewing and sterilization without breaking or perforating.

[0026] The one-way ventilation valve, generally indicated by 16 in the drawings, has a tent-like structure consisting of two rectangular or trapezoidal side walls 16a, 16b and two triangular end walls 16c. At the ridge of the tent-like structure, the side walls 16a, 16b meet along a slit which opens to allow a...

Abstract

A teat for a feeding bottle has a one-way valve 16 located remotely from the nipple of the teat to allow air to enter the feeding bottle to replace liquid sucked out of the bottle through the nipple while preventing liquid from leaking from the bottle. The one-way valve 16 comprises an inwardly-oriented depression having opposed mutually inclined sidewalls lea and 16b meeting along a ridge having a slit. In the invention, when undeflected, the side walls lea and 16b make line contact with one another at the ridge and the thickness of the side walls is less than 0.4 mm so that, when acted upon by an increased pressure in the feeding bottle, the side walls collapse against one another and make sealing contact along a surface that extends from the ridge in the direction away from it.

Description

technical field [0001] The present invention relates to teats for feeding bottles. Background technique [0002] The baby is able to suck continuously from its mother's breast without needing ventilation. So when babies try to suck from a feeding bottle nipple, they don't know they need ventilation. If the baby does not stop sucking to allow air to enter the feeding bottle, the pressure drop in the bottle and the resulting reverse suction makes it more difficult for the baby to suck liquid from the bottle. In addition to preventing the baby from trying to suck, there are two serious consequences. First, because of the need to apply an incremental suction, the baby's lips become unable to form an effective seal around the teat, and the baby ends up swallowing air and the liquid, the trapped air causing the baby to colic. Second, the dome of the teat collapses inward, making it difficult for the baby's lips to maintain a grip on the teat. [0003] Various attempts have bee...
