To provide a push removing cap made of a plastic which can be opened by one hand.

A guaranty strip (2) is formed in one piece, via a break-off web (6), on the push removing cap (1) on which a push piece (5) is arranged on a rim skirt (4) including a covering face (3) and the rim skirt (4). The guaranty strip (2) is designed as a closing ring without a tab. The diameter of the break-off web (6) can be changed so that the push removing cap (1) can be opened by one hand. In particular, a break-off web in the region of the push piece (5) is designed thinner than a break-off web arranged following it. An extremely thin break-off web is protected with a supporting cam arranged in the middle space between the lower edge of the the rim skirt (4) and the upper edge of the annular guaranty strip (2) in order to prevent damage occurred at being arranged on the cap, to provide a very narrow gap (8).
