<p>An infant feeding vessel 1 such as a bottle has a body portion 5 between a base 7 and an outlet 17 which is convoluted, undulating or castellated so as to define four protrusions in the form of castellations or fins which extend longitudinally from the body portion base towards the body portion outlet, enabling a reduced body wall thickness at mid height and providing efficient thermal change to be transferred through a contained liquid whilst allowing efficient manufacture by such as blow moulding and efficient use of material in its production.</p> |
