A closure device (1) for a product dispensing container. The closure device comprises a base (2) having a body with a connector portion (2a) adapted to mount the closure device on a product container. The base comprises a product channel (5) and a rupturable seal (4) occluding the product channel and forming a lower seal of the closure device. A rotary part (20) is rotatably journalled on the base. The rotary part has a product passage (21) in communication with the product channel in the base. An upper sealing arrangement (30) is arranged on the rotary part and forms an upper seal of the closure device that is remote from the lower seal and seals the product passage of the rotary part. A lower seal rupturing member (40) is movable in a rupturing motion relative to the base to rupture the rupturable lower seal. A motion transfer (27, 42, 3b, 41) means is provided and is adapted so as to effect the rupturing motion of the lower seal rupturing member upon suitable rotary actuation of the rotary part. A protective overcap (10) is removable by the user. |
