The present invention is designed to reliably prevent unintentional operation of a depress-and-rotate-type content release operating part and to stabilize and improve sliding operation of said operating part to select a locked mode or an unlocked mode and depressing operation for releasing the contents. A guide member (2a) is provided with guides (2k, 2n) for guiding the sliding operation of the operating part (1). The operating part (1) is provided with guided parts (1g, 1j), which are respectively guided and held by the guides, and a content passage (3)-driving part (1f). In the locked mode in which the operating part (1) is in a forward position, the guided parts (1g, 1j) are respectively held by the guides (2k, 2n) and content-releasing operation of the operating part is inhibited. In the unlocked mode shown in which the operating part (1) is moved backward, said held sate is cancelled. As a result of a depressing operation of the operating part (1), the operating part rotates centered on the guided part (1g), the driving part (1f) presses a driven part (3d) downward, and the content passage (3) and the stem (4) assume a content-releasing configuration. |
