Abstract
A dispensing closure for dispensing fluid product from a squeeze container consists of an outer cap element (3) and an inner element or valve disc (4) fitting inside the cap element. Each is moulded from thermoplastics; no elastomer is used. The cap element includes an outwardly-deflectable diaphragm wall (35) around a central outlet opening (361). The inner element (4) has a peripheral mounting ring (41), a central blocking portion (48) and a set of support spokes (46) providing flow clearance between them. In a closed position the blocking portion closes the outlet opening. In an outflow condition the diaphragm wall (35) deflects outwardly to allow flow. In a recovery mode the blocking portion (48) deflects inwardly for compensation air or residual liquid product to enter the container.
