Infant feeding bottle - bulges on closure are each side of projection of bottle opening after release

摘要

Bottle is as in DT 2109743. The bulges limit the movement of the closure, which seals the interior of the bottle relative to the interior of the teat and is held within the teat by friction, but which can be displaced from the sealing position by actuation of the teat cap, and in this position enables a free flow of liquid from the bottle into the teat. Preferably the internal projection of the bottle has an annular edge behind which can be brought one of the bulges of the closure in one direction, in the displaced position of the closure, but which prevents return in the opposite direction.
