<p>A one-push openable cap mechanism, in which a cap and a plug can be easily opened in one-push action by fingers. Specifically, a cap mechanism provided with a hinge (4) and used with a container (15), comprising hook mechanisms (8, 9) formed on the sides of a cap body (1) and a cover respectively (2) and wedge-shaped in their directions and turning, a spout (10) formed on the cap body (1), a plug (11) formed on the cover, the spout and the plug being inclined at the same angle in the direction of turning, two slits (6, 6) provided to extend from the cap body (1) to the cover (2) across the hinge (4), bends (7), respectively, provided on the ends of the two slits (6, 6) on the cover (2), and a pressure releasing portion (5) comprising a portion surrounded by the portions of the two slits (6, 6) on the cap body (1) and positions thereof reaching the cover (2). In the opening action, a user holds the container (15) in one hand and performs one-push manipulation on the pressure releasing portion (5) in the direction of turning with fingers of the same hand to release fastened hooks (8, 9) on the turning side to separate the plug (11) and the cover (2) formed at the same inclination angle up to a necessary angle in one action from the spout (10), which is also inclined in the direction of turning. To attain integral formation of the cap, along with an assured hooking function and closability and reliable opening operability and appropriate pouring of the contents, directionality is set which is common to the formation of the cap and the opening action of the cap.</p> |
