Abstract: A teat unit has a teat, a securing device for securing the teat on a liquid container, and an air valve, the securing device having a first securing part and a second securing part. The air valve has a first valve part, which is arranged in the first securing part, and a second valve part, which is arranged in the first or in the second securing part. The air valve opens and closes with respect to the second securing part. The valve is preferably a diaphragm valve, and the first valve part is a valve diaphragm. This teat unit functions very reliably even at very small pressure differences between the bottle and the environment. Moreover, the range of function of the various teat units of the same type is relatively narrow, such that different teat units function very similarly and the air valves are actuated at similar pressure differences.

Abstract: A modular feeding system assembled as an upright, hands-free feeding bottle or a traditional nurser bottle (which requires holding the bottle during feeding). The pressure equalization features of such an assembled device may have health benefits to the user or care giver. The other complementary, modular parts can be used to convert the bottle (or other suitable container) into a sippy cup or a sports bottle. The parts offer versatility in bottle feeding to the user, whether it is an infant, toddler, adult, elderly person or animal.

Further, the vent insert has a major and minor seal that prevents leaks out of the collar and onto an infant.

Abstract: Feeding bottle (10) comprising a neck to which a teat (14) is attached, characterized in that it comprises at least two visual marks (20, 22) located on one and the same circumference near the neck or near the teat and separated from one another about the axis of the feeding bottle, one of these marks (20) defining one angular position of the feeding bottle (10) about its axis for which the other mark (22) indicates a point through which the free surface (24) of the liquid contained in the feeding bottle needs to pass in order for the hydrostatic pressure of the liquid at an outlet orifice (16) of the teat (14) to be substantially zero.

Abstract: Colic can be a particular problem for babies feeding on liquid feed from a feeder bottle. The colic can be formed by air from various sources in the liquid feed. Typically, there is less air in the liquid feed towards the bottom of the liquid feed container in the feeding position than towards the top of the liquid feed. The present invention provides apparatus for drawing milk from the bottom of the feeding apparatus chamber when the feeder is held in the operating position. This is achieved by positioning a flow restrictor for allowing the passage of liquid feed from a main chamber into a flexible feeding teat at a suitable location. The present invention also provides a resiliently-biased cartridge to assist in priming and/or draining of the flexible feeding teat. The present invention also provides a construction in which the flow restrictor is always provided in the correct position regardless of the relative angular orientation of the elements of the feeder.
