ABSTRACT:
A closure includes a capping part (1), which is attachable to a container, in which a form-stable floor wall (9) has a sealing apparatus (11) with a sealing cone (13) is held to the rest of the capping part by means of a flexible wall area so that the sealing cone can be brought into and out of a sealing engagement relationship with a mouth opening (5) of the container. Measures are provided, for example in the form of inversions of a flexible wall area (12), to hold the sealing apparatus in end positions corresponding to open and closed positions of the sealing apparatus. In the end positions the sealing apparatus (11) can be moved by hand via an integral hand-manipulation portion (15). A pour spout (16) can be formed on the flexible wall area (12) so that it experiences a swinging upon movement of the sealing apparatus (11) between the closing and opening position corresponding to the respective positions of the flexible wall area.
