Dispensing closure for a fluid container

Dispensing closure (100) for a container (10) with a spout (20) for dispensing a fluid, said dispensing closure comprising

• a peripheral wall (200) adapted to at least partly fit within the spout and to seal against the spout, when the closure (100) is in its closed position,
• a transverse wall (300) extending inside of the peripheral wall (200), and
• a toggle member (400) extending from the transverse wall (300) to be manipulated by a user,
• wherein said peripheral wall (200) and said transverse wall (300) are made of an elastic material, and
• wherein said closure (100) is arranged and adapted such that
• a) the closure (100) is in its closed position when no force is exerted by a user onto said toggle member (400), and
• b) at least part of the transverse wall (300) and at least part of the peripheral wall (200) are distorted when a force is exerted onto said toggle member (400) by a user such that the seal between the peripheral wall (200) and the spout of the container (10) is at least partly opened to bring the closure (100) in its opened position and to permit dispensing of the fluid out of the container (10),
• wherein said dispensing closure (100) further comprises a valve element (500), said valve element (500) being provided in said transverse wall (300) and being arranged such that it is closed when said closure (100) is in its closed position and such that it is at least partly open when said closure (100) is in its opened position to permit flow of air into said container (100).
