A NURSING BOTTLE ASSEMBLY AND A REUSABLE LINER THEREFOR

摘要

A nursing bottle assembly (1) comprises a rigid outer casing (3), a flexible inner liner(2) and a teat arrangement (5, 6). The teat arrangement (5, 6) attaches to the outer casing (2) and secures the inner liner (2) in position within the outer casing (3). The flexible inner liner (2) comprises a container in the form of a bellows such that it expands and collapses in a predictable linear manner along its longitudinal axis. Preferably, the inner liner (2) is moulded from a food- grade silicone or thermoplastic elastomer and comprises a substantially cylindrical container formed with at least one projecting rib (9, 14, 16) or groove (18) about which the liner (2) folds to enable it to expand and collapse in a predictable linear manner along its longitudinal axis.
