Vessel for use in infant's feeding bottle, has rupture structure arranged inside compartment for successively causing rupture of portions of central walls of vessel during deformation of vessel

摘要

The vessel (21) has a fixation unit for fixing the vessel to a vial. A rupture structure arranged inside a compartment (40) successively causes rupture of portions of primary and secondary central walls (33, 38) of the vessel during deformation of the vessel. The rupture structure is formed with a striker (27) extending into the compartment. A primary strut (29) is provided at a lower end of the striker, and a secondary strut (30) is provided at an upper end of the striker, where the vessel and the vial are formed by molding of plastic materials. An independent claim is also included for a container comprising a liner whose base extends between a wall of a vessel and a wall of a cap.
