A container, consisting of an at least partially filled container body, and of at least one cap part (10), which has at least one sealing part (16) which, for removal of the container contents, can be penetrated by a hollow-spike-like insertion part (22) from the outside, with a predeterminable actuating force, in an introduction direction, it being possible for said insertion part to be removed from the container again, with a predeterminable pull-out force, in an oppositely directed pull-out direction, is characterized by the presence of a device (16, 18) which makes it difficult for the insertion part (22) to be removed and by means of which the pull-out force is increased such that unintentional removal of the insertion part (22) is at least made difficult.
